Assessment of cardiovascular risk by use of multiple-risk-factor assessment equations: a statement for healthcare professionals from the American Heart Association and the American College of Cardiology

What People Want: Exercise and Personalized Intervention as Preferred Strategies to Improve Well-Being and Prevent Chronic Diseases

Background/Objectives: The workplace represents an ideal context for applying policies to foster a healthy lifestyle, guaranteeing advantages both to the individual and the company. Nevertheless, motivation to change one's lifestyle remains an issue. This study aimed to determine subjects' most valued intentions toward lifestyle changes and the target actions to improve lifestyles that they would be willing to invest in economically, information which might help design effective intervention programs. Methods: Classification trees were applied to 2762 employees/ex-employees (55.09 ± 13.80 years; 1107 females and 1655 males) of several Italian companies who voluntarily filled out an anonymous questionnaire on lifestyles (inquiring about, e.g., exercise, nutrition, smoking, and stress) to unveil specific subject typologies that are more likely associated with, e.g., manifesting a specific intention toward lifestyle changes and choosing the two most popular target actions resulting from the survey. Results: The main lifestyle aspect that respondents desired to improve was to become more physically active, and the most preferred tools chosen to improve their lifestyle were the possibility of having a medical specialist consultant to prescribe a tailored lifestyle program and buying a gym/swimming pool membership. Conclusions: This observational study might help tailor worksite health promotion and insurance services offered to employees, initiatives that may play an important role in fostering health/well-being and preventing chronic diseases in the more general population, especially in healthy or young subjects who are more prone to change their behavior if immediate benefits are seen instead of only advantages in the future.

Leveraging technology and standardized institutional practices to mitigate disparities in breast cancer radiation therapy

OBJECTIVES

Disparities in various dimensions, including racial, in breast cancer treatment and outcomes are well established. A recent multi-institutional study reported a higher mean heart dose (MHD) in Black and minority women compared to White women who underwent left-sided breast/chest wall irradiation which translated into excess cardiac events and mortality. We evaluated the MHD of women treated in our institution and investigated whether institution-wide measures including the use of readily available but inconsistently adopted technologies can mitigate this disparity.

METHODS

We identified 509 female patients treated with left-sided breast/chest wall irradiation with/without regional nodal irradiation (RNI). Details regarding cardiac dosimetry, deep-inspiratory breath-hold (DIBH) such as active breathing coordinator (ABC) use, breast size, internal mammary nodal (IMN) irradiation, and whether the treatment plan met boarding pass requirements and was peer reviewed were noted. MHD differences across racial groups were analyzed using Kruskal-Wallis test, while UVA and MVA linear regression analyses assessed influence of various factors on MHD.

RESULTS

MHD(Gy) was similar across racial groups; 1.38, 1.35, and 1.39 (p = 0.6) in Black, White, and other racial groups, respectively. Utilization of hypofractionation, cavity boosts, RNI, IMN irradiation, meeting boarding pass requirements, and peer review were similar. ABC usage (%) was 83/75/62 (p = 0.005), while median breast size(cc) was 1504/1904/1331 (p = 0.001) in White/Black/other women, respectively. On UVA and MVA, MHD differed with IMN treatment, boost and ABC use but not racial groups and varying breast sizes.

CONCLUSION

Despite anatomical differences such as breast size, achieving similar cardiac dose is feasible across racial groups by uniformly utilizing appropriate technology such as ABC, with standardized boarding pass constraints, and peer review of all cases. Further studies to identify factors that may cause varied cardiac morbidity rates despite similar cardiac dosimetry among racial groups are warranted.

Association of vitamin D and bisphenol A levels with cardiovascular risk in an elderly Italian population: results from the InCHIANTI study

Few studies have evaluated the association between circulating levels of 25-hydroxyvitamin D (25(OH)D), 1,25-dihydroxyvitamin D (1,25(OH)2D), and the endocrine disruptor bisphenol A (BPA), with risk of cardiovascular (CV) disease in elderly individuals. This was a cross-sectional study in a subgroup of elderly people from the InCHIANTI Biobank in Italy. We examined the association between circulating serum vitamin D metabolites, 1,25(OH)2D, 25(OH)D, and the endocrine disrupting agent BPA, with an arbitrary CV risk score and the European Society of Cardiology-based 10-year CV risk (SCORE2/SCORE2-OP) using univariate and multiple regression. In 299 individuals, blood samples were tested for serum values of 25(OH)D, 1,25(OH)2D and urinary BPA levels. One hundred eighty individuals (60.2%) were deficient (< 20 ng/ml) in 25(OH)D. Levels of 25(OH)D and 1,25(OH)2D were negatively correlated with CV risk score (p < 0.0001 for both) as well as SCORE2/SCORE2-OP (p < 0.0001 for both) while BPA levels were positively correlated with both CV risk scores (p < 0.0001 for both). In a logistic regression model, male gender (odds ratio; OR: 2.1, 95% CI:1.1-3.8, p = 0.022), obesity (OR:2.8, 95% CI:1.2-6.5, p = 0.016) and BPA levels ≥ 110 ng/dl (OR:20.9, 95% CI:9.4-46.8, p < 0.0001) were associated with deficient levels of 25(OH)D. 1,25(OH)2D levels < 41 ng/dl and 25(OH)D levels < 20 ng/ml were associated with CV risk score ≥ 3 (OR: 4.16, 95% CI: 2.32-7.4, p < 0.0001 and OR: 1.86, 95% CI: 1.02-3.39, p = 0.044) respectively and 1,25(OH)2D levels < 41 ng/dl were associated with SCORE2/SCORE2-OP of ≥ 20% (OR:2.98, 95% CI: 1.7-5.2, p = 0.0001). In this cross-sectional analysis, BPA exposure was associated with significantly reduced levels of vitamin D that in turn were significantly associated with increased CV risk.

The MARVIN Hypothesis: Linking Unhealthy Lifestyles to Intracranial Aneurysm Rupture Risk and Clinical Prognosis

Background and Objectives: The rising incidence of modifiable lifestyle risk factors and cardiovascular diseases, driven by poor diet, inactivity, excessive alcohol use, and smoking, may influence the development and rupture of intracranial aneurysms (IA). This study aimed to examine the impact of lifestyle-related and cardiovascular risk factors on IA rupture and patient outcomes. Materials and Methods: We developed the "MARVIN" (Metabolic and Adverse Risk Factors and Vices Influencing Intracranial Aneurysms) model and conducted a retrospective analysis of 303 patients with 517 IAs, treated between 2007 and 2020. Of these, 225 patients were analyzed for rupture status and 221 for clinical outcomes. The analysis focused on hypertension, diabetes, hypercholesterolemia, vascular diseases, nicotine and alcohol abuse, obesity, aneurysm rupture status, and clinical outcomes. Logistic regression was used to evaluate the impact of these risk factors. Results: Among those with risk factors, 24.9% (56/225) and 25.3% (56/221) had one, 32.0% (72/225) and 30.8% (68/221) had two, 20.0% (45/225) and 20.4% (45/221) had three, 12.0% (27/225) and 12.2% (27/221) had four, 4.0% (9/225) and 4.1% (9/221) had five, 0.9% (2/225) had six in both groups, and 0.4% (1/225) and 0.5% (1/221) had seven risk factors, respectively. Strong relationships were found between lifestyle-related vascular risk factors, indicating multiple comorbidities in patients with unhealthy habits. Smokers with ruptured aneurysms had higher WFNS (World Federation of Neurosurgical Societies) scores, but nicotine abuse did not affect long-term outcomes. The most significant predictors for poor outcomes were WFNS score and age, while age and a history of vascular diseases were protective against rupture. Despite the high prevalence of modifiable risk factors, they did not significantly influence rupture risk. Conclusions: The findings suggest a need for multifactorial risk assessment strategies in managing IA patients. Future studies with larger cohorts are required to confirm these results and better understand IA progression.

Waist-to-hip ratio as a contributor associated with higher atherosclerotic cardiovascular disease risk assessment in patients with diabetes: a cross-sectional study

INTRODUCTION

This study aimed to identify the factors most strongly associated with an increased atherosclerotic cardiovascular disease (ASCVD) risk score in patients with type 2 diabetes (T2D).

METHODS

This cross-sectional study included 4698 patients with T2D over an 11-year period (2010-2021). Patients were categorized into four groups based on their 10-year ASCVD risk score (< 5%, 5-7.5%, 7.5-20%, and > 20%). Multinominal regression analysis was used to evaluate the association between various modifiable and non-modifiable risk factors and the ASCVD risk score.

RESULTS

Of the patients, 35.9% had a 10-year ASCVD risk score below 5%, 12.6% had a score between 5% and 7.5%, 30.8% had a score between 7.5% and 20%, and 19.7% had a score above 20%. Higher ASCVD risk scores were significantly associated with elevated waist-to-hip ratio (WHR > 0.93), pulse pressure, uric acid, triglycerides, and decreased glomerular filtration rate (all p-values < 0.05). WHR demonstrated the strongest association with higher ASCVD risk scores (OR: 4.55, 95% CI: 2.94-7.03, p < 0.001) when comparing patients with ASCVD scores > 5% to those with scores < 5%.

CONCLUSION

WHR was independently associated with higher ASCVD risk scores in patients with T2D. Incorporating WHR, along with traditional risk factors, could improve ASCVD risk assessments in this population.

Comparison of the performance of cardiovascular risk prediction tools in rural India: the Rishi Valley Prospective Cohort Study

AIMS

We compared the performance of cardiovascular risk prediction tools in rural India.

METHODS AND RESULTS

We applied the World Health Organization Risk Score (WHO-RS) tools, Australian Risk Score (ARS), and Global risk (Globorisk) prediction tools to participants aged 40-74 years, without prior cardiovascular disease, in the Rishi Valley Prospective Cohort Study, Andhra Pradesh, India. Cardiovascular events during the 5-year follow-up period were identified by verbal autopsy (fatal events) or self-report (non-fatal events). The predictive performance of each tool was assessed by discrimination and calibration. Sensitivity and specificity of each tool for identifying high-risk individuals were assessed using a risk score cut-off of 10% alone or this 10% cut-off plus clinical risk criteria of diabetes in those aged >60 years, high blood pressure, or high cholesterol. Among 2333 participants (10 731 person-years of follow-up), 102 participants developed a cardiovascular event. The 5-year observed risk was 4.4% (95% confidence interval: 3.6-5.3). The WHO-RS tools underestimated cardiovascular risk but the ARS overestimated risk, particularly in men. Both the laboratory-based (C-statistic: 0.68 and χ2: 26.5, P = 0.003) and non-laboratory-based (C-statistic: 0.69 and χ2: 20.29, P = 0.003) Globorisk tools showed relatively good discrimination and agreement. Addition of clinical criteria to a 10% risk score cut-off improved the diagnostic accuracy of all tools.

CONCLUSION

Cardiovascular risk prediction tools performed disparately in a setting of disadvantage in rural India, with the Globorisk performing best. Addition of clinical criteria to a 10% risk score cut-off aids assessment of risk of a cardiovascular event in rural India.

LAY SUMMARY

In a cohort of people without prior cardiovascular disease, tools used to predict the risk of cardiovascular events varied widely in their ability to accurately predict who would develop a cardiovascular event.The Globorisk, and to a lesser extent the ARS, tools could be appropriate for this setting in rural India.Adding clinical criteria, such as sustained high blood pressure, to a cut-off of 10% risk of a cardiovascular event within 5 years could improve identification of individuals who should be monitored closely and provided with appropriate preventive medications.

Aerobic, resistance, or combined exercise training and cardiovascular risk profile in overweight or obese adults: the CardioRACE trial

BACKGROUND AND AIMS

To determine the comparative efficacy of resistance, aerobic, and combined resistance plus aerobic exercise on cardiovascular disease (CVD) risk profile.

METHODS

This randomized controlled trial enrolled 406 adults aged 35-70 years with overweight or obesity and elevated blood pressure. Participants were randomly assigned to resistance (n = 102), aerobic (n = 101), combined resistance plus aerobic exercise (n = 101), or no-exercise control (n = 102). All exercise participants were prescribed 1 h of time-matched supervised exercise (the combination group with 30 min of each resistance and aerobic exercise) three times per week for 1 year. The primary outcome was the change from baseline to 1 year in the standardized composite Z-score of four well-established CVD risk factors: systolic blood pressure, low-density lipoprotein (LDL) cholesterol, fasting glucose, and per cent body fat.

RESULTS

Among 406 participants (53% women), 381 (94%) completed 1-year follow-up. Compared with the control group, the composite Z-score decreased at 1 year, which indicates improved CVD risk profile, in the aerobic {mean difference, -0.15 [95% confidence interval (CI): -0.27 to -0.04]; P = .01} and combination [mean difference, -0.16 (95% CI: -0.27 to -0.04); P = .009] groups, but not in the resistance [mean difference, -0.02 (95% CI: -0.14 to 0.09); P = .69] group. Both aerobic and combination groups had greater reductions in the composite Z-score compared with the resistance group (both P = .03), and there was no difference between the aerobic and combination groups (P = .96). Regarding the four individual CVD risk factors, only per cent body fat decreased in all three exercise groups at 1 year, but systolic blood pressure, LDL cholesterol, and fasting glucose did not decrease in any exercise groups, compared with the control group.

CONCLUSIONS

In adults with overweight or obesity, aerobic exercise alone or combined resistance plus aerobic exercise, but not resistance exercise alone, improved composite CVD risk profile compared with the control.

Impact of body mass index in patients with tricuspid regurgitation after transcatheter edge-to-edge repair

BACKGROUND

Obesity and underweight represent classical risk factors for outcome in patients treated for cardiovascular disease. This study describes the impact of different body mass index (BMI) categories on 1-year clinical outcome in patients with tricuspid regurgitation (TR) undergoing transcatheter-edge-to-edge repair (TEER).

METHODS

We analyzed 211 consecutive patients (age 78.3 ± 7.2 years, 55.5% female, median EuroSCORE II 9.6 ± 6.7) with tricuspid regurgitation undergoing TEER from June 2015 until May 2021. Patients were prospectively enrolled in our single center registry and were retrospectively analyzed. Patients were stratified according to body mass index (BMI) into 4 groups: BMI < 20 kg/m2 (underweight), BMI 20.0 to < 25.0 kg/m2 (normal weight), BMI 25.0 to > 30.0 kg/m2 (overweight) and BMI ≥ 30 kg/m2 (obese).

RESULTS

Kaplan-Meier survival curves demonstrated inferior survival for underweight and obese patients, but comparable outcomes for normal and overweight patients (global log rank test, p < 0.01). Cardiovascular death was significantly higher in underweight patients compared to the other groups (24.1% vs. 7.0% vs. 6.3% vs. 6.4%; p < 0.01). Over all, there were comparable rates of bleeding, stroke and myocardial infarction. Multivariable Cox regression analysis (adjusted for age, gender, coronary artery disease, chronic obstructive pulmonary disease, tricuspid annular plane systolic excursion, left-ventricular ejection fraction) confirmed underweight (HR 3.88; 95% CI 1.64-7.66; p < 0.01) and obesity (HR 3.24; 95% CI 1.37-9.16; p < 0.01) as independent risk factors for 1-year all-cause mortality.

CONCLUSIONS

Compared to normal weight and overweight patients, obesity and underweight patients undergoing TEER display significant higher 1-year all-cause mortality.

Increasing Activity After Stroke: A Randomized Controlled Trial of High-Intensity Walking and Step Activity Intervention

BACKGROUND

Physical inactivity in people with chronic stroke profoundly affects daily function and increases recurrent stroke risk and mortality, making physical activity improvements an important target of intervention. We compared the effects of a high-intensity walking intervention (FAST), a step activity monitoring behavioral intervention (SAM), or a combined intervention (FAST+SAM) on physical activity (ie, steps/day). We hypothesized the combined intervention would yield the greatest increase in steps/day.

METHODS

This assessor-blinded multisite randomized controlled trial was conducted at 4 university/hospital-based laboratories. Participants were 21 to 85 years old, walking without physical assistance following a single, unilateral noncerebellar stroke of ≥6 months duration, and randomly assigned to FAST, SAM, or FAST+SAM for 12 weeks (2-3 sessions/week). FAST training consisted of walking-related activities at 70% to 80% heart rate reserve, while SAM received daily feedback and goal setting of walking activity (steps/day). Assessors and study statistician were masked to group assignment. The a priori-determined primary outcome and end point was a comparison of the change in steps/day between the 3 intervention groups from pre- to post-intervention. Adverse events were tracked after randomization. All randomized participants were included in the intent-to-treat analysis.

RESULTS

Participants were enrolled from July 18, 2016, to November 16, 2021. Of 2385 participants initially screened, 250 participants were randomized (mean [SE] age, 63 [0.80] years; 116 females/134 males), with 89 assigned to FAST, 81 to SAM, and 80 to FAST+SAM. Steps/day significantly increased in both the SAM (mean [SE], 1542 [267; 95% CI, 1014-2069] P<0.001) and FAST+SAM group (1307 [280; 95% CI, 752-1861] P<0.001) but not in the FAST group (406 [238; 95% CI, -63 to 876] P=0.09). There were no deaths or serious study-related adverse events.

CONCLUSIONS

Only individuals with chronic stroke who completed a step activity monitoring behavioral intervention with skilled coaching and goal progression demonstrated improvements in physical activity (steps/day).

Arterial Age and Early Vascular Aging, But Not Chronological Age, Are Associated With Faster Thoracic Aortic Aneurysm Growth

Background Aneurysm size is an imperfect risk assessment tool for those with thoracic aortic aneurysm (TAA). Assessing arterial age may help TAA risk stratification, as it better reflects aortic health. We sought to evaluate arterial age as a predictor of faster TAA growth, independently of chronological age. Methods and Results We examined 137 patients with TAA. Arterial age was estimated according to validated equations, using patients' blood pressure and carotid-femoral pulse wave velocity. Aneurysm growth was determined prospectively from available imaging studies. Multivariable linear regression assessed the association of chronological age and arterial age with TAA growth, and multivariable logistic regression assessed associations of chronological and arterial age with the presence of accelerated aneurysm growth (defined as growth>median in the sample). Mean±SD chronological and arterial ages were 62.2±11.3 and 54.2±24.5 years, respectively. Mean baseline TAA size and follow-up time were 45.9±4.0 mm and 4.5±1.9 years, respectively. Median (interquartile range) TAA growth was 0.31 (0.14-0.52) mm/year. Older arterial age (ß±SE for 1 year: 0.004±0.001, P<0.0001) was independently associated with faster TAA growth, while chronological age was not (P=0.083). In logistic regression, each 5-year increase in arterial age was associated with a 23% increase in the odds of accelerated TAA growth (95% CI, 1.085-1.394; P=0.001). Conclusions Arterial age is independently associated with accelerated aneurysm expansion, while chronological age is not. Our results highlight that a noninvasive and inexpensive assessment of arterial age can potentially be useful for TAA risk stratification and disease monitoring as compared with the current clinical standard (chronological age).

Increasing activity after stroke: a randomized controlled trial of highintensity walking and step activity intervention

Background

Physical inactivity in people with chronic stroke profoundly affects daily function and increases recurrent stroke risk and mortality, making physical activity improvements an important target of intervention. We compared the effects of a highintensity walking intervention (FAST), a step activity monitoring behavioral intervention (SAM), or a combined intervention (FAST+SAM) on physical activity (i.e., steps per day). We hypothesized the combined intervention would yield the greatest increase in steps per day.

Methods

This assessor-blinded multi-site randomized controlled trial was conducted at four university/hospital-based laboratories. Participants were 21-85 years old, walking without physical assistance following a single, unilateral non-cerebellar stroke of ≥6 months duration, and randomly assigned to FAST, SAM, or FAST+SAM for 12 weeks (2-3 sessions/week). FAST training consisted of walking-related activities for 40 minutes/session at 70-80% heart rate reserve, while SAM received daily feedback and goal-setting of walking activity (steps per day). Assessors and study statistician were masked to group assignment.The a priori-determined primary outcome and primary endpoint was change in steps per day from pre- to post-intervention. Adverse events (AEs) were tracked after randomization. All randomized participants were included in the intent-to-treat analysis.This study is registered at ClinicalTrials.gov, NCT02835313.

Findings

Participants were enrolled from July 18, 2016-November 16, 2021. Of 250 randomized participants (mean[SE] age 63[0.80], 116F/134M), 89 were assigned to FAST, 81 to SAM, and 80 to FAST+SAM. Steps per day significantly increased in both the SAM (mean[SE] 1542[267], 95%CI:1014-2069, p<0.001) and FAST+SAM groups (1307[280], 752-1861, p<0.001), but not in the FAST group (406[238], 63-876, p=0.09). There were no deaths or serious study-related AEs and all other minor AEs were similar between groups.

Interpretation

Only individuals with chronic stroke who completed a step activity monitoring behavioral intervention with skilled coaching and goal progression demonstrated improvements in physical activity (steps per day).

Absolute cardiovascular risk assessment by Australian early-career general practitioners: a cross-sectional study

OBJECTIVE

To determine the prevalence and associations of general practice registrars' performing absolute cardio-vascular risk (ACVR) assessment (ACVRa).

DESIGN

A cross-sectional study employing data (2017-2018) from the Registrar Clinical Encounters in Training project, an ongoing inception cohort study of Australian GP registrars. The outcome measure was whether an ACVRa was performed. Analyses employed univariable and multivariable regression. Analysis was conducted for all patient problems/diagnoses, then for an 'at-risk' population (specific problems/diagnoses for which ACVRa is indicated).

SETTING

Three GP regional training organisations (RTOs) across three Australian states.

PARTICIPANTS

GP registrars training within participating RTOs.

RESULTS

1003 registrars (response rate 96.8%) recorded details of 69 105 problems either with Aboriginal and/or Torres Strait patients aged 35 years and older or with non-Indigenous patients aged 45 years and older. Of these problems/diagnoses, 1721 (2.5% (95% CI 2.4% to 2.6%)) involved an ACVRa. An ACVRa was 'plausibly indicated' in 10 384 problems/diagnoses. Of these, 1228 (11.8% (95% CI 11.2% to 12.4%)) involved ACVRa. For 'all problems/diagnoses', on multivariable analysis female gender was associated with reduced odds of ACVRa (OR 0.61 (95% CI 0.54 to 0.68)). There was some evidence for Aboriginal and/or Torres Strait Islander people being more likely to receive ACVRa (OR 1.40 (95% CI 0.94 to 2.08), p=0.10). There were associations with variables related to continuity of care, with reduced odds of ACVRa: if the patient was new to the registrar (OR 0.65 (95% CI 0.57 to 0.75)), new to the practice (OR 0.24 (95% CI 0.15 to 0.38)) or the problem was new (OR 0.68 (95% CI 0.59 to 0.78)); and increased odds if personal follow-up was organised (OR 1.43 (95% CI 1.24 to 1.66)). For 'ACVRa indicated' problems/diagnoses, findings were similar to those for 'all problems/diagnoses'. Association with Aboriginal and/or Torres Strait Islander status, however, was significant at p<0.05 (OR 1.60 (95% CI 1.04 to 2.46)) and association with female gender was attenuated (OR 0.88 (95% CI 0.77 to 1.01)).

CONCLUSION

Continuity of care is associated with registrars assessing ACVR, reinforcing the importance of care continuity in general practice. Registrars' assessment of an individual patient's ACVR is targeted to patients with individual risk factors, but this may entail ACVRa underutilisation in female patients and younger age groups.

Possible molecular mechanisms underlying the development of atherosclerosis in cancer survivors

Cancer survivors undergone treatment face an increased risk of developing atherosclerotic cardiovascular disease (CVD), yet the underlying mechanisms remain elusive. Recent studies have revealed that chemotherapy can drive senescent cancer cells to acquire a proliferative phenotype known as senescence-associated stemness (SAS). These SAS cells exhibit enhanced growth and resistance to cancer treatment, thereby contributing to disease progression. Endothelial cell (EC) senescence has been implicated in atherosclerosis and cancer, including among cancer survivors. Treatment modalities for cancer can induce EC senescence, leading to the development of SAS phenotype and subsequent atherosclerosis in cancer survivors. Consequently, targeting senescent ECs displaying the SAS phenotype hold promise as a therapeutic approach for managing atherosclerotic CVD in this population. This review aims to provide a mechanistic understanding of SAS induction in ECs and its contribution to atherosclerosis among cancer survivors. We delve into the mechanisms underlying EC senescence in response to disturbed flow and ionizing radiation, which play pivotal role in atherosclerosis and cancer. Key pathways, including p90RSK/TERF2IP, TGFβR1/SMAD, and BH4 signaling are explored as potential targets for cancer treatment. By comprehending the similarities and distinctions between different types of senescence and the associated pathways, we can pave the way for targeted interventions aim at enhancing the cardiovascular health of this vulnerable population. The insights gained from this review may facilitate the development of novel therapeutic strategies for managing atherosclerotic CVD in cancer survivors.

The hypertension and hyperlipidemia status among type 2 diabetic patients in the community and influencing factors analysis of glycemic control

OBJECTIVE

To understand the prevalence of hypertension and hyperlipidaemia as well as the current status of glycaemic control and its influencing factors among type 2 diabetes mellitus patients in the community in South China, and to provide recommendations for the prevention and control of diabetes.

METHODS

Questionnaires, physical examinations and laboratory tests were conducted on patients with type 2 diabetes mellitus who participated in the National Basic Public Health Service Programme in Guangzhou in 2020. The chi-square test, t-test and multi-factor unconditional logistic regression analysis were performed using R 4.1.2 software.

RESULT

Among 127,423 type 2 diabetic patients in Guangzhou, 57,695 achieved glycemic control standards, with a glycemic control rate of 45.28%.In this study, the proportion of T2DM patients with hypertension and hyperlipidaemia together was 27.79%, The percentage of T2DM patients with hypertension alone and hyperlipidaemia alone was 28.34% and 20.53% respectively, and the rate of no complications was 23.34%. There was a statistically significant difference in the rate of glycaemic control between the different disease combination states (P < 0.05). The glycaemic control rate was 47.67% in diabetic patients without hypertension and hyperlipidaemia, 52.54% and 37.24% in those with combined hypertension alone and hyperlipidaemia alone respectively, compared to 41.80% in diabetic patients with hypertension and hyperlipidaemia. After adjusting for all covariates, multivariate analysis showed that combined hypertension alone was associated with good glycaemic control (OR 0.817, 95% CI 0.791, 0.843, P < 0.001),when using comorbid T2DM as a control group, combined hyperlipidaemia alone, combined hypertension and hyperlipidaemia were associated with poor glycaemic control (OR 1.521, 95% CI 1.470,1.574, P < 0.001 and OR 1.250, 95% CI 1.211,1.291, P < 0.001), Subgroup analyses as well as multifactorial unconditional logistic regression analyses showed that patients with type 2 diabetes who were overweight and obese, smoked, drank alcohol, had a diagnosis of diabetes for ≥ 6 years, had fair or poor adherence and had a family history of diabetes had lower rates of glycaemic control.

CONCLUSION

The results of this study showed that the co-morbidity of hypertension and hyperlipidaemia was high and prevalent among diabetic patients in Guangzhou. Moreover, glycaemic control of T2DM patients with hyperlipidaemia was lower than other diabetic patients. Obesity and overweight, poor lifestyle and dietary habits are also major factors affecting the treatment and control of T2D patients in this region. Therefore, comprehensive measures should be actively taken to control blood glucose levels in type 2 diabetic patients by also incorporating lipid management into the community and strictly controlling lipid levels.

Risk Factors Control After an Acute Coronary Syndrome and Association with Major Adverse Cardiovascular Events: A Single Center Experience in Latin-America

INTRODUCTION

An important challenge in the secondary prevention of cardiovascular diseases is the optimization of risk factors (RFs) after hospital discharge. These have been shown to be insufficiently controlled in clinical practice.

AIM

To evaluate whether secondary prevention goals were met at our institution at 12 months after an acute coronary syndrome (ACS) index event, as well as analyzing if achieving these goals was associated with a lower incidence of major adverse cardiovascular events (MACE).

METHODS

Retrospective cohort of patients with a former diagnosis of ACS over a period of 4 years. To evaluate the proportion of patients who met RF control goals at 12 months after the index event, we used two sets of preestablished goals: stringent and lenient. During follow-up we evaluated the occurrence of MACE, defined by the following: ACS, coronary revascularization, stroke, hospitalization because of acute heart failure and cardiovascular death.

RESULTS

We included 468 patients during the study period. The mean age of the patients was 60 ± 10.76 years, 20.5% were women, and mean follow-up was 41.8 ± 22.0 months. The proportion of patients that met all secondary prevention stringent and lenient goals accounted for 5.5% and 17.2%, respectively, and 8% did not achieve any target. Overall, 9.6% presented the composite of MACE during follow-up. The number of RFs in control at 12 months was associated with a lower rate of MACE, both with stringent and lenient goals.

CONCLUSION

Achieving established goals for modifiable RFs can lower the incidence of MACE during long-term follow-up.

Individual and combined contributions of non-high-density lipoprotein cholesterol and brachial-ankle pulse wave velocity to cardiovascular disease risk: Results of a prospective study using the Kailuan cohort

OBJECTIVE

We aimed to characterize the relationship of a combination of circulating non-high-density lipoprotein-cholesterol (non-HDL-C) concentration and brachial-ankle pulse wave velocity (baPWV) with cardiovascular disease (CVD).

METHODS

We performed a prospective cohort study of the residents of the Kailuan community, with data from a total of 45,051 participants being included in the final analysis. The participants were allocated to four groups according to their non-HDL-C and baPWV status, each of which was categorized as high or normal. Cox proportional hazards models were used to explore the relationships of non-HDL-C and baPWV, individually and in combination, with the incidence of CVD.

RESULTS

During the 5.04-year follow-up period, 830 participants developed CVD. Compared with the Normal non-HDL-C group independently, the multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for CVD in the High non-HDL-C was 1.25 (1.08-1.46). Compared with the Normal baPWV group independently, the HRs and 95% CIs for CVD in the High baPWV was 1.51 (1.29-1.76). In addition, compared with the Normal both non-HDL-C and baPWV group, the HRs and 95% CIs for CVD in the High non-HDL-C and normal baPWV, Normal non-HDL-C and high baPWV, and High both non-HDL-C and baPWV groups were 1.40 (1.07-1.82), 1.56 (1.30-1.88), and 1.89 (1.53-2.35), respectively.

CONCLUSION

High non-HDL-C concentration and high baPWV are independently associated with a higher risk of CVD, and individuals with high both non-HDL-C and baPWV are at a still higher risk of CVD.

Hazard-based risk grouping effectively stratifying breast cancer patients in post-irradiation long-term heart diseases: a population-based cohort study

Background

Even though advanced radiotherapy techniques provide a better protective effect on surrounding normal tissues, the late sequelae from radiation exposure to the heart are still considerable in breast cancer patients. The present population-based study explored the role of cox-regression-based hazard risk grouping and intended to stratify patients with post-irradiation long-term heart diseases.

Materials and methods

The present study investigated the Taiwan National Health Insurance (TNHI) database. From 2000 to 2017, we identified 158,798 breast cancer patients. Using a propensity score match of 1:1, we included 21,123 patients in each left and right breast irradiation cohort. Heart diseases, including heart failure (HF), ischemic heart disease (IHD), and other heart diseases (OHD), and anticancer agents, including epirubicin, doxorubicin, and trastuzumab, were included for analysis.

Results

Patients received left breast irradiation demonstrated increased risks on IHD (aHR, 1.16; 95% CI, 1.06-1.26; p < 0.01) and OHD (aHR, 1.08; 95% CI, 1.01-1.15; p < 0.05), but not HF (aHR, 1.11; 95% CI, 0.96-1.28; p = 0.14), when compared with patients received right breast irradiation. In patients who received left breast irradiation dose of >6,040 cGy, subsequent epirubicin might have a trend to increase the risk of heart failure (aHR, 1.53; 95% CI, 0.98-2.39; p = 0.058), while doxorubicin (aHR, 0.59; 95% CI, 0.26-1.32; p = 0.19) and trastuzumab (aHR, 0.93; 95% CI, 0.33-2.62; p = 0.89) did not. Older age was the highest independent risk factor for post-irradiation long-term heart diseases.

Conclusion

Generally, systemic anticancer agents are safe in conjunction with radiotherapy for managing post-operative breast cancer patients. Hazard-based risk grouping may help stratify breast cancer patients associated with post-irradiation long-term heart diseases. Notably, radiotherapy should be performed cautiously for elderly left breast cancer patients who received epirubicin. Limited irradiation dose to the heart should be critically considered. Regular monitoring of potential signs of heart failure may be conducted.

Development of a prediction model to estimate the 5-year risk of cardiovascular events and all-cause mortality in haemodialysis patients: a retrospective study

Background

Cardiovascular disease (CVD) is a major cause of mortality in patients on haemodialysis. The development of a prediction model for CVD risk is necessary to help make clinical decisions for haemodialysis patients. This retrospective study aimed to develop a prediction model for the 5-year risk of CV events and all-cause mortality in haemodialysis patients in China.

Methods

We retrospectively enrolled 398 haemodialysis patients who underwent dialysis at the dialysis facility of the General Hospital of Northern Theater Command in June 2016 and were followed up for 5 years. The composite outcome was defined as CV events and/or all-cause death. Multivariable logistic regression with backwards stepwise selection was used to develop our new prediction model.

Results

Seven predictors were included in the final model: age, male sex, diabetes, history of CV events, no arteriovenous fistula at dialysis initiation, a monocyte/lymphocyte ratio greater than 0.43 and a serum uric acid level less than 436 mmol/L. Discrimination and calibration were satisfactory, with a C-statistic above 0.80. The predictors lay nearly on the 45-degree line for agreement with the outcome in the calibration plot. A simple clinical score was constructed to provide the probability of 5-year CV events or all-cause mortality. Bootstrapping validation showed that the new model also has similar discrimination and calibration. Compared with the Framingham risk score (FRS) and a similar model, our model showed better performance.

Conclusion

This prognostic model can be used to predict the long-term risk of CV events and all-cause mortality in haemodialysis patients. An MLR greater than 0.43 is an important prognostic factor.

Disparities in Surgical Timing and Guideline-Adherent Staging Work-Up for Colon Cancer

BACKGROUND

Expedited or delayed surgery for colon cancer without appropriate work-up increases mortality risk. We sought to identify what patient, social, and hospital factors were associated with timely, guideline-adherent work-up for colon cancer.

METHODS

Retrospective analysis of 19,046 patients in the Surveillance, Epidemiology, and End Results (SEER) database linked with Medicare administrative claims who underwent elective surgery for colon cancer between 2010 and 2015 was performed. Primary outcome was receipt of complete preoperative work-up (colonoscopy, imaging, tumor marker evaluation) and timely surgery within 60 days of diagnosis. Patients were stratified into four groups: (1) adherent; (2) early surgery (< 30 days) with incomplete work-up; (3) surgery between 30 and 60 days with incomplete work-up; and (4) late surgery (> 60 days) with/without work-up. Characteristics were compared and multinomial logistic regression was performed.

RESULTS

Overall, 46.2% of patients received adherent care, 33.1% had early surgery and inadequate work-up, 10.3% had appropriately timed surgery but incomplete work-up, and 10.4% underwent late surgery. Multivariable analysis demonstrated that older, female, Black, and unmarried patients as well as patients living in areas with higher rates of poverty were more likely to receive non-adherent care. A greater proportion of patients at teaching hospitals received complete work-up (57.6% vs. 49.5%) but also underwent late surgery (12.4% vs. 8.6%) compared with non-teaching hospitals.

CONCLUSIONS

Patient, societal, and hospital factors impact whether patients receive guideline-adherent colon cancer care. Interventions are needed to improve access to timely and guideline-adherent cancer care as a possible mechanism to combat surgical disparities.

Acrylamide exposure increases cardiovascular risk of general adult population probably by inducing oxidative stress, inflammation, and TGF-β1: A prospective cohort study

Acrylamide (ACR) exposure and consequent health hazards are alarming public health issues that attract worldwide concern. The World Health Organization urges more researches into health hazards from ACR exposure. However, whether and how ACR exposure increases cardiovascular risk remain unclear, and we sought to address these issues in this prospective cohort study conducted on 3024 general adults with 3-year follow-up (N = 871 at follow-up). Individual urinary ACR metabolites (N-Acetyl-S-(2-carbamoylethyl)-L-cysteine [AAMA] and N-Acetyl-S-(2-carbamoyl-2-hydroxyethyl)-L-cysteine [GAMA]) as credible biomarkers of ACR exposure were detected to assess their cross-sectional and longitudinal relationships with 10-year cardiovascular disease (CVD) risk, a well measure of overall cardiovascular risk. Besides, biomarkers of oxidative stress (urinary 8-hydroxy-deoxyguanosine [8-OHdG] and 8-iso-prostaglandin-F2α [8-iso-PGF2α]) and inflammation (circulating mean platelet volume [MPV] and plasma C-reactive protein [CRP]) as well as plasma transforming growth factor-β1 (TGF-β1) were measured to assess their mediating/mechanistic roles in the relationships of ACR metabolites with 10-year CVD risk. We found AAMA, GAMA, and ΣUAAM (AAMA + GAMA) were cross-sectionally and longitudinally related to increased 10-year CVD risk with odds ratios (95% confidence intervals [CIs]) of 1.32 (1.04, 1.70), 1.81 (1.36, 2.40), and 1.40 (1.07, 1.82), respectively, and risk ratios (95% CIs) of 1.99 (1.10, 3.60), 2.48 (1.27, 4.86), and 2.13 (1.15, 3.94), respectively. Furthermore, 8-OHdG, 8-iso-PGF2α, MPV, CRP, and TGF-β1 were found to significantly mediate 8.06-48.92% of the ACR metabolites-associated 10-year CVD risk increment. In summary, daily ACR exposure of general adults was cross-sectionally and longitudinally associated with increased cardiovascular risk, which was partly mediated by oxidative stress, inflammation, and TGF-β1, suggesting for the first time that ACR exposure may well increase cardiovascular risk of general adult population partly by mechanisms of inducing oxidative stress, inflammation, and TGF-β1. Our findings have important public health implications that provide potent epidemiological evidence and vital mechanistic insight into cardiovascular risk increment from ACR exposure.

Cardiovascular diseases among diffuse large B-cell lymphoma long-term survivors in Asia: a multistate model study

BACKGROUND

We modeled the clinical course of a cohort of diffuse large B-cell lymphoma (DLBCL) patients with no prior cardiovascular diseases (CVDs) using a multistate modeling framework.

PATIENTS AND METHODS

Data on 2600 patients with DLBCL diagnosed between 2000 and 2018 and had received chemotherapy with or without radiotherapy were obtained from a population-wide electronic health database of Hong Kong. We used the Markov illness-death model to quantify the impact of doxorubicin and various risk factors (therapeutic exposure, demographic, comorbidities, cardiovascular risk factors, and lifestyle factors which included smoking) on the clinical course of DLBCL (transitions into incident CVD, lymphoma death, and other causes of death).

RESULTS

A total of 613 (23.6%) and 230 (8.8%) of 2600 subjects died of lymphoma and developed incident CVD, respectively. Median follow-up was 7.0 years (interquartile range 3.8-10.8 years). Older ages [hazard ratio (HR) for >75 versus ≤60 years 1.88; 95% confidence interval (CI) 1.25-2.82 and HR for 61-75 versus ≤60 years 1.60; 95% CI 1.12-2.30], hypertension (HR 4.92; 95% CI 2.61-9.26), diabetes (HR 1.43; 95% CI 1.09-1.87), and baseline use of aspirin (HR 5.30; 95% CI 3.93-7.16) were associated with an increased risk of incident CVD. In a subgroup of anticipated higher-risk patients (aged 61-75 years, smoked, had diabetes, and received doxorubicin), we found that they remained on average 7.9 (95% CI 7.2-8.8) years in the DLBCL state and 0.1 (95% CI 0.0-0.4) years in the CVD state, if they could be followed up for 10 years. The brief time in the CVD state is consistent with the high chance of death in patients who developed CVD. Other causes of death have overtaken DLBCL-related death after about 5 years.

CONCLUSIONS

In this Asian population-based cohort, we found that incident CVDs can occur soon after DLBCL treatment and continued to occur throughout survivorship. Clinicians are advised to balance the risks and benefits of treatment choices to minimize the risk of CVD.

Roles of Nutraceuticals and Functional Food in Prevention of Cardiovascular Disease

The chapter provides an overview of cardiovascular disease, a major cause of mortality worldwide. It relates economic and social impacts to the disease, especially in developing countries. One of the approaches to addressing this challenge is increasing awareness within society, through implementation of education programs. It is important for society to understand the types and roles of the risk factors leading to cardiovascular disease. Emphasis is on the role of functional food and nutraceuticals as dietary sources that could prevent development of cardiovascular disease. The chapter highlights roles of nutraceuticals and functional food sources from medical plants, seeds, berries, and tropical fruits in lowering risk factors. Key findings from trials conducted in Asia, China, Europe, and America provide supporting evidence for the importance of functional food to health, and its potential for modifying the level of risk factors related to cardiovascular diseases.

Prevention paradox between stroke and multiple potential risk factors using data from a population-based cohort study

Previous studies have found the prevention paradox in the association between stroke events and a single specific risk factor, indicating that a population-based strategy may be more effective than a high-risk-based strategy for prevention. We tested the hypothesis that the prevention paradox does not apply when focusing on multiple potential risk factors simultaneously. The study cohort included 9051 individuals from Japan aged 40-89 years. The time-dependent Cox proportional-hazards models were used to identify the primary risk factor associated with stroke onset. We classified participants based on risk factors in two distinct ways: 1) classifying the high-risk group participants according to a single specific risk factor that had a large association with stroke in both sexes and all ages and 2) classifying the high-risk group participants according to 1-3 risk factor(s) including hypertension, hyperglycemia, and/or dyslipidemia. Then, we compared the proportions of the total number of participants who developed stroke in both groups to assess the prevention paradox. We found that hypertension was a primary risk factor for stroke incidence, regardless of sex and age. The percentage of patients with a single specific risk of and developed stroke was 46%-63%, while the percentage of patients with 1-3 risk factor(s) was 71-83%. This finding leads to the conclusion that the prevention paradox does not hold when multiple stroke risk factors were associated, suggesting that a high-risk-based strategy that focuses on patients with multiple risk factors may be more effective in preventing strokes.

Management of Ischemic Heart Disease in Pregnancy

PURPOSE OF REVIEW

Cardiovascular disease is an escalating cause of maternal morbidity and mortality. Women are at risk for acute myocardial infarction (MI), and more are living with risk factors for ischemic heart disease (IHD). The purpose of this review is to describe the evaluation and management of women at risk for and diagnosed with IHD in pregnancy.

RECENT FINDINGS

Pregnancy can provoke MI which has been estimated as occurring in 1.5-10/100, 000 deliveries or 1/12,400 hospitalizations, with a high inpatient mortality rate of approximately 5-7%. An invasive strategy may or may not be preferred, but fetal radiation exposure is less of a concern in comparison to maternal mortality. Common medications used to treat IHD may be continued successfully during pregnancy and lactation, including aspirin, which has an emerging role in pregnancy to prevent preeclampsia, preterm labor, and maternal mortality. Hemodynamics can be modulated during pregnancy, labor, and postpartum to mitigate risk for acute decompensation in women with IHD. Cardiologists can successfully manage IHD in pregnancy with obstetric partners and should engage women in a lifetime of cardiovascular care.

Building a Cardiovascular Disease Prediction Model for Smartwatch Users Using Machine Learning: Based on the Korea National Health and Nutrition Examination Survey

Smartwatches have the potential to support health care in everyday life by supporting self-monitoring of health conditions and personal activities. This paper aims to develop a model that predicts the prevalence of cardiovascular disease using health-related data that can be easily measured by smartwatch users. To this end, the data corresponding to the health-related data variables provided by the smartwatch are selected from the Korea National Health and Nutrition Examination Survey. To classify the prevalence of cardiovascular disease with these selected variables, we apply logistic regression, artificial neural network, and support vector machine among machine learning classification techniques, and compare the appropriateness of the algorithm through classification performance indicators. The prediction model using support vector machine showed the highest accuracy. Next, we analyze which structures or parameters of the support vector machine contribute to increasing accuracy and derive the importance of input variables. Since it is very important to diagnose cardiovascular disease early correctly, we expect that this model will be very useful if there is a tool to predict whether cardiovascular disease develops or not.

Design and rationale of the randomized trial of comprehensive lifestyle modification, optimal pharmacological treatment and utilizing PET imaging for quantifying and managing stable coronary artery disease (the CENTURY study)

BACKGROUND

The literature reports no randomized trial in chronic coronary artery disease (CAD) of a comprehensive management strategy integrating intense lifestyle management, maximal medical treatment to specific goals and high precision quantitative cardiac positron emission tomography (PET) for identifying high mortality risk patients needing essential invasive procedures. We hypothesize that this comprehensive strategy achieves greater risk factor reduction, lower major adverse cardiovascular events and fewer invasive procedures than standard practice.

METHODS

The CENTURY Study (NCT00756379) is a randomized-controlled-trial study in patients with stable or at high risk for CAD. Patients are randomized to standard of care (Standard group) or intense comprehensive lifestyle-medical treatment to targets and PET guided interventions (Comprehensive group). Comprehensive Group patients are regularly consulted by the CENTURY team implementing diet/lifestyle/exercise program and medical treatment to target risk modification. Cardiac PET at baseline, 24-, and 60-months quantify the physiologic severity of CAD and guide interventions in the Comprehensive group while patients and referring physicians of the Standard group are blinded to PET results. The primary end-point is the CENTURY risk score reduction during 5 years follow-up. The secondary endpoint is a composite of death, non-fatal myocardial infarction, stroke, and coronary revascularization.

CONCLUSIONS

The CENTURY Study is the first study in stable CAD to test the incremental benefit of a comprehensive strategy integrating intense lifestyle modification, medical treatment to specific goals, and high-precision quantitative myocardial perfusion imaging to guide revascularization. A total of 1028 patients have been randomized, and the 5 years follow-up will conclude in 2022.

Low-Density Lipoprotein Cholesterol 4: The Notable Risk Factor of Coronary Artery Disease Development

Background: Coronary artery disease (CAD) is the leading cause of death worldwide, which has a long asymptomatic period of atherosclerosis. Thus, it is crucial to develop efficient strategies or biomarkers to assess the risk of CAD in asymptomatic individuals.

Methods: A total of 356 consecutive CAD patients and 164 non-CAD controls diagnosed using coronary angiography were recruited. Blood lipids, other baseline characteristics, and clinical information were investigated in this study. In addition, low-density lipoprotein cholesterol (LDL-C) subfractions were classified and quantified using the Lipoprint system. Based on these data, we performed comprehensive analyses to investigate the risk factors for CAD development and to predict CAD risk.

Results: Triglyceride, LDLC-3, LDLC-4, LDLC-5, LDLC-6, and total small and dense LDL-C were significantly higher in the CAD patients than those in the controls, whereas LDLC-1 and high-density lipoprotein cholesterol (HDL-C) had significantly lower levels in the CAD patients. Logistic regression analysis identified male [odds ratio (OR) = 2.875, P < 0.001], older age (OR = 1.018, P = 0.025), BMI (OR = 1.157, P < 0.001), smoking (OR = 4.554, P < 0.001), drinking (OR = 2.128, P < 0.016), hypertension (OR = 4.453, P < 0.001), and diabetes mellitus (OR = 8.776, P < 0.001) as clinical risk factors for CAD development. Among blood lipids, LDLC-3 (OR = 1.565, P < 0.001), LDLC-4 (OR = 3.566, P < 0.001), and LDLC-5 (OR = 6.866, P < 0.001) were identified as risk factors. To predict CAD risk, six machine learning models were constructed. The XGboost model showed the highest AUC score (0.945121), which could distinguish CAD patients from the controls with a high accuracy. LDLC-4 played the most important role in model construction.

Conclusions: The established models showed good performance for CAD risk prediction, which can help screen high-risk CAD patients in asymptomatic population, so that further examination and prevention treatment might be taken before any sudden or serious event.

Total cholesterol/HDL-C ratio versus non-HDL-C as predictors for ischemic heart disease: a 17-year follow-up study of women in southern Sweden

BACKGROUND

A distorted blood lipid profile is an important risk factor for ischemic heart disease (IHD) but the predictive ability of the different lipid measures has rarely been studied. Our aim was to examine and compare, in a large sample of women, the predictive ability of total cholesterol/HDL cholesterol ratio (TC/HDL-C) and non-HDL-C in relation to IHD, adjusted for age, exercise, smoking, waist-hip ratio, blood pressure, and diabetes mellitus.

METHODS

Between 1995 and 2000, a total of 6537 women aged 50-59 years from the Women's Health in Lund area (WHILA) study in southern Sweden were included and underwent a baseline examination. The women were followed through national registers for incidence of IHD during a mean follow-up of 17 years. The prediction accuracy was estimated through Harrell's C and Akaike Information Criterion (AIC).

RESULTS

Increasing TC/HDL-C as well as non-HDL-C showed strong associations with IHD, with the highest risk in the 5th quintile, where the HR was 2.30 (95% CI: 1.70-3.11) for TC/HDL-C and 1.67 (95% CI: 1.25-2.24) for non-HDL-C, after adjustments. Comparisons using Harrell's C and AIC indicated that TC/HDL-C has a slightly higher predictive ability than that of non-HDL-C (Harrell's C 0.62 and 0.59 respectively, p = 0.003 for difference, age-adjusted model; AIC for TC/HDL-C < AIC for non-HDL-C).

CONCLUSIONS

TC/HDL-C ratio and non-HDL-C are both clinical predictors for IHD in middle-aged women. The results indicate that the predictive ability of TC/HDL-C was higher than that of non-HDL-C; however, non-HDL-C was linearly related to IHD (p = 0.58) and may be easier to calculate and interpret in clinical practice, for early identification of future IHD in women.

Prevalence of obesity and associated cardiovascular risk factors in the Spanish population: the ENPE study

INTRODUCTION AND OBJECTIVES

Obesity is a significant public health problem associated with an increased risk of cardiovascular risk factors (CVRF). The aim of this study was to determine the prevalence of overweight and abdominal obesity (AO) in the Spanish population aged ≥ 3 years and to analyze the influence of sociodemographic and lifestyle factors and their association with CVRF.

METHODS

The sample was drawn from the ENPE study (n=6800). The study protocol included individual anthropometric measurements, sociodemographic factors, food intake (food frequency questionnaire), physical activity, lifestyles, and health problems.

RESULTS

The estimated overall prevalence of obesity (22.0%; 95%CI, 21.0-23.0) and AO (64.7%; 95%CI, 63.5-65.8) was higher in men, in persons aged ≥ 65 years, and in those with a lower socioeconomic level or from southern regions. Lifestyle pattern was significantly associated with obesity and AO (P=.011), which were less likely in people with an active lifestyle pattern (P <.0001). Obesity (OR, 1.85; 95%CI, 1.24-2.78) and AO (OR, 2.16; 95%CI, 1.1-4.24) were positively associated with CVRF. Clustering of CVRF with obesity and/or AO was higher in women (12.6%; 95%CI, 11.4-13.9) and in persons aged ≥ 65 years (32.7%; 95%CI, 30.0-35.4).

CONCLUSIONS

The prevalence of obesity and AO in the Spanish population is high; it is higher in men, increases with age, and is inversely related to socioeconomic status. A lifestyle pattern combining a higher level of physical activity, moderate sedentariness and a Mediterranean dietary pattern is associated with a lower probability of obesity, AO, and CVRF.

A systematic review of the effect of dietary interventions on cardiovascular disease risk in adults with spinal cord injury

CONTEXT

Cardiovascular disease is one of the leading causes of mortality in individuals with spinal cord injury (SCI), highlighting the need for targeted risk minimization interventions.

OBJECTIVE

To determine the effect of dietary interventions on CVD risk in adults with SCI.

METHODS

A systematic literature review of studies investigating the impact of dietary intervention on CVD risk in SCI individuals was conducted according to the PRISMA statement. CASP checklists were used for critical appraisal, Academy of Nutrition and Dietetics Quality criteria checklist (QCC) for determining risk of bias and the GRADE approach to ascertain the quality of evidence of the outcomes. The results were reported descriptively.

RESULTS

A total of eight studies were included from the identified 862 articles. Dietary intervention strategies varied across all studies, as did the outcome measures. Adult learning theories were not considered. The lack of controlled trials (two only) meant that while some interventions proved useful, risk of bias was high. Outcome measures were assessed as low to very low quality again identifying that this area is highly under-researched.

CONCLUSION

Despite documented evidence of the benefits of diet on CVD risk reduction, this review has identified a dearth of research in SCI. Nonetheless, the review emphasizes the potential of diet in conjunction with exercise in minimizing CVD risk in SCI. Further good quality research backed by robust data collection, simple, actionable strategies and knowledge translation techniques are essential to ascertain the effects of dietary intervention in lowering CVD risk in SCI.

Early Elective Surgery After Colon Cancer Diagnosis has Higher Risk of Readmission and Death

OBJECTIVE

We hypothesized colon resection within 30 days of diagnosis of cancer would have higher rates of readmission and cancer specific mortality, unless there was demonstrated evidence of preoperative workup.

SUMMARY BACKGROUND DATA

Few studies have examined if negative consequences exist with expedited elective surgery after diagnosis of colon cancer. Surgery in a shorter time frame may result in a lack of appropriate preoperative care.

METHODS

Retrospective analysis of 25,407 patients in the Surveillance Epidemiology and End Results registry who underwent elective surgical resection for colon cancer from 2010 to 2015. Cohort stratified by age (66-75 vs >75 years). Primary outcomes of interest were 30-day readmission and 5-year colon cancer specific mortality. Relationships between timing of surgery and outcomes were assessed.

RESULTS

On unadjusted analysis, surgery before 20 days of diagnosis was associated with higher risk of 30-day readmission and colon cancer specific mortality in both age groups. Among those age 66 to 75 years old, adjusting for patient factors and preoperative workup eliminated the risk of 30-day readmission (risk ratio 1.5-0.9 for 0-10 days, risk ratio 1.3-0.9 for 11-20 days). However, the risk for colon cancer specific mortality, although reduced, persisted (hazard ratio 2.2-1.3 for 0-10 days, hazard ratio 2.0-1.2 for 11-20 days). In the cohort older than 75 years, adjusting for patient level factors and preoperative workup eliminated risk of surgery 20 days postop or sooner.

CONCLUSIONS

The risk associated with short time to surgery (within 30 days) may be mitigated if full oncologic workups are provided.

Exercise capacity, cardiovascular and metabolic risk of the sample of German police officers in a descriptive international comparison

Background: The police force has the mandate to protect citizens and enforce the law for public safety. Employment in the police force is recognized as a dangerous occupation and characterized by job-related physical hazards. Therefore, good health and adequate physical condition are necessary. This study aimed to determine cardiovascular, cardiorespiratory, and metabolic risk parameters of German police officers (POs) in comparison to POs from other nations. Methods: 55 male police officers from Germany participated in the survey. We examined anthropometric measurements, cardiovascular/metabolic risk factors and blood parameters. Additionally, we calculated 10-year cardiovascular risk using the Framingham Risk Score. The diagnosis of metabolic syndrome bases on the criteria of the International Diabetes Federation. We assessed cardiorespiratory status by exercise spirometry. Results: The analyzed group of POs demonstrated a high prevalence of pre obesity (BMI: 28.0±3.2 kg/m², waist circumference: 97.8±12.4 cm). 61.8 % of POs showed an increased waist circumference. POs showed high prevalence of abnormal values of triglyceride (n: 24, 43,6%), and systolic (n: 29, 52,7%) and diastolic (n: 27, 49%) blood pressure. The average 10-year cardiovascular risk (by Framingham) was classified as moderate (9.6 ± 7.4 %). 32 % (n: 18) of POs in our study group were diagnosed with metabolic syndrome. Maximal relative oxygen uptake of POs was 34.1 ± 8.0 ·ml/kg^-1 ·min^-1. Conclusions: To our knowledge, this study was one of the first to assess data on cardiovascular health, metabolic syndrome and cardiorespiratory status of police officers in Germany. The results of our study demonstrated an increased cardiovascular and metabolic risk and decreased cardiorespiratory fitness in German police officers. The present study results underline the need to implement health-promoting interventions and concepts like corporate sports activities or nutrition courses to counteract cardiovascular and metabolic risk factors. We have to reduce the subsequent development of cardiovascular and metabolic disease in this occupational group.

Risk factors for coronary heart disease and family medicine: What can be done?

Background / Aim: More people die each year due to cardiovascular diseases (CVDs) than from any other cause. The most common cause of ischaemic heart diseases (IHD) is atherosclerosis of the coronary arteries. Risk factors for the development of coronary heart disease (CHD) can be preventable and non-preventable. The aim of the study was to determine the frequency of individual risk factors in patients with CHD. Methods: Retrospective analysis included patients with diagnoses of stable angina pectoris (AP), unstable angina pectoris and myocardial infarction - acute coronary syndrome (ACS) and ischaemic cardiomyopathy (iCMP). The prevalence of the following risk factors for IHD was analysed: hypertension, diabetes, obesity, cholesterol, smoking, family history, age and sex. Data were taken from the Register of Patients with Chronic Diseases and Risk Factors and electronic patient records. Results: Of the total number of respondents older than 18, 4.95 % had CHD. Of the 178 patients with IHD, 70 (39.3 %) patients had AP, 60 (33.7 %) patients had ACS and 48 (27.0 %) patients had iCMP. Positive family history had 63.5 % of patients, 72 % were older than 66, 24.1 % were smokers and 74.2 % of patients had elevated blood cholesterol levels. Diabetes mellitus affected 29.2 % of patients, hypertension 88.8 %, and BMI ≥ 25 kg/m2 had 70.8 % of patients. Of the total number of patients with ACS, 68.3 % were men, while higher percentage of women suffered from AP (62.9 %) (p = 0.002). In the age below 65, CHD was more common in men (p = 0.007). Cholesterol was elevated more often in patients with AP than iCMP (p = 0.001). Patients with ACS were more likely to have diabetes mellitus compared to patients with AP and iCMP (p = 0.010). Conclusion: The prevalence of preventable risk factors is alarmingly high. Of particular importance is the timely detection and treatment of risk factors by family physicians and strengthening the personal responsibility of each individual in choosing their lifestyle and active involvement in the therapeutic process.

Assessment of Age-Induced Changes in Body Fat Percentage and BMI Aided by Bayesian Modelling: A Cross-Sectional Cohort Study in Middle-Aged and Older Adults

Background

Loss of fat-free mass (FFM) and gain in body fat (BF) are the key disability risk factors, also instrumental in perpetuating already existing functional disorders. Obesity construed in terms of body mass index (BMI) values, in view of undesirable gain in BF, is a risk factor for cardio-metabolic disorders. Both detrimental processes clearly evidence a scope of involutionary changes characteristic of an aging population, also standing for one of its greatest burdens.

Purpose

The present study aimed to assess the changes in body composition (BC), in conjunction with the relationship between BF% and BMI, for defining overweight and obesity status in middle-aged and older adults, against the select indicator variables under study.

Materials and Methods

The study involved 4799 individuals (33.7% men), PONS Project participants, aged 43-64 years. BF% was measured with the aid of bioelectrical impedance analysis (BIA) method. Age-induced changes in BC were determined against BF%, fat mass (FM), FFM, BMI, fat mass index (FMI), and fat-free mass index (FFMI). The relationship between BF% and BMI was established with the aid of Bayesian regression models, adjusted for gender and age.

Results

In both genders, BF% increased with age at a similar annual rate. The reduction of FFM was noted mainly in men, which in conjunction with BF% gain ensured BMI stability. The increase in BF% in women with stable FFM affected an increase in BMI. Regardless of the BMI threshold, the anticipated (predicted) BF% increased with age in both genders.

Conclusion

Monitoring of BC is of particular importance in older adults, in view of appreciably better characteristics of both the short- and long-term health predictors, as well as overall potential for developing specifically targeted, effective health interventions.

Impact of the COVID-19 pandemic in patients with a previous history of premature myocardial infarction

Objectives

The coronavirus-disease-2019 (COVID-19) pandemic has led to the restructuring of health-services to prioritize the treatment of COVID-19. The severe restrictions on daily life affected the management of chronic diseases. Patients with a previous history of premature myocardial infarction (MI) are a vulnerable group requiring frequent and continued medical attention both in the pandemic and non-pandemic era. The present study was conducted to provide insight into the impact of COVID-19 outbreak on heart-healthy lifestyle and management of patients with a history of premature MI.

Methods

This cross-sectional study included 170 consecutive patients with a history of premature MI who were already in regular follow-up in a tertiary out-patient prevention clinic before the pandemic. Inclusion criteria included age ≥18 years and being on regular follow up with the diagnosis of premature MI (documented MI before the age of 55 years) at least for one year. All patients were contacted by phone-call and replied to a 23-item questionnaire measuring the impact of the pandemic on the management, healthy lifestyle habits, and anxiety level.

Results

One patient died due to COVID-19 infection; therefore the analyses were conducted in 169 patients (age: 47.67 ​± ​11.84 years, 21.3% women). The median age at first MI was 39 (IQR 10) years and the median time elapsed since the first MI was 7 years (IQR 10). The study population was highly compliant with the follow-up visits (78.1%) and pharmacological therapy (97%) before the pandemic according to the medical files. The majority (82.2%) of the patients were aware that having a history of premature MI would increase the risk and harm of COVID-19. Anxiety level increased in 62.7% of the study patients. Overall, 65.7% of the patient group reported a disruption at least in ≥1 component(s) of healthy life-behaviors (non-compliance with the heart-healthy diet, an increase in alcohol intake, an increase in smoking, and/or reduced physical activity) since the emergence of the outbreak. The anxiety level (p ​= ​0.001) and the prevalence of appetite change (p ​< ​0.0001) and weight gain (p ​< ​0.0001) was lower in the lifestyle compliant group than the non-compliant group. Avoidance of seeking medical care was reported in 33.7% of the patients. Statin use was 99.4% before the pandemic and decreased to 89.9% (p ​< ​0.0001) ​despite the fact that medications were reimbursed and widely available.

Conclusions

The COVID-19 pandemic significantly affected the heart-healthy lifestyle and anxiety levels of patients with a history of premature MI who were already in regular follow-up in a tertiary prevention clinic and led to significant avoidance of medical care. More rigorous follow-up, education, and reassurance of these patients with telemedicine are necessary for the prevention of further increase in their risk.

An Overview of the Role of Adipokines in Cardiometabolic Diseases

Obesity as an independent risk factor for cardiovascular diseases (CVDs) leads to an increase in morbidity, mortality, and a shortening of life span. The changes in heart structure and function as well as metabolic profile are caused by obese people, including those free of metabolic disorders. Obesity alters heart function structure and affects lipid and glucose metabolism, blood pressure, and increase inflammatory cytokines. Adipokines, specific cytokines of adipocytes, are involved in the progression of obesity and the associated co-morbidities. In the current study, we review the scientific evidence on the effects of obesity on CVDs, focusing on the changes in adipokines. Several adipokines have anti-inflammatory and cardioprotective effects comprising omentin, apelin, adiponectin, and secreted frizzled-related protein (Sfrp-5). Other adipokines have pro-inflammatory impacts on the cardiovascular system and obesity including leptin, tumor necrosis factor (TNF), retinol-binding protein4 (RBP-4), visfatin, resistin, and osteopontin. We found that obesity is associated with multiple CVDs, but can only occur in unhealthy metabolic patients. However, more studies should be designed to clarify the association between obesity, adipokine changes, and the occurrence of CVDs.

Doxorubicin and subsequent risk of cardiovascular diseases among survivors of diffuse large B-cell lymphoma in Hong Kong

Evidence regarding the dose-related impact of doxorubicin on subsequent cardiovascular diseases (CVDs) in Asian patients with diffuse large B-cell lymphoma (DLBCL) without preexisting CVDs is lacking. From a territory-wide electronic database in Hong Kong, we identified adults who were diagnosed with DLBCL and treated with chemotherapy between 2000 and 2018. We evaluated the patients for incident CVDs (including ischemic heart disease, heart failure, and cardiomyopathy). We evaluated the cause-specific cumulative incidence (csCI) of CVD with levels of doxorubicin exposure by using flexible parametric competing risk analysis and adjusting for demographics, comorbidities, therapeutic exposure, cardiovascular risk factors, and lifestyle factors. Controls were age- and sex-matched to DLBCL patients. We analyzed 2600 patients and 13 000 controls. The adjusted cause-specific hazard ratio (HR) for CVD in patients treated with >500 mg doxorubicin compared with non-doxorubicin regimens was 2.65 (95% confidence interval [CI], 1.23-5.74; P = .013). The 5-, 10-, and 15-year csCIs were 8.2%, 11.3%, and 12.8% in patients vs 3.1%, 4.4%, and 5.2% in controls, respectively. Hypertension (HR, 6.20; 95% CI, 0.79-48.44; P = .082) and use of aspirin/angiotensin-converting enzyme inhibitor/beta-blocker at baseline (HR, 2.13-4.63; P < .001 to .002) might confer a higher risk of subsequent CVDs. In this Hong Kong population-based study, doxorubicin exposure (absolute dose >500 mg), together with hypertension or baseline use of medication for cardiovascular risk factors, was found to be associated with an increase in csCIs of CVDs. Tailoring therapeutic strategies to underlying CVD risk factors and risk-adapted monitoring and follow-up of susceptible DLBCL patients are advisable.

Blood Pressure during Blood Collection and the Implication for Absolute Cardiovascular Risk Assessment

Background

Blood collection and blood pressure (BP) measurements are routinely performed during the same consultation to assess absolute cardiovascular disease (CVD) risk. This study aimed to determine the effect of blood collection on BP and subsequent calculation of the absolute CVD risk.

Methods

Forty-five participants aged 58 ± 9 years (53% male) had systolic BP (SBP) measured using clinical guideline methods (clinic SBP). Then, on a separate visit, BP was measured immediately before, during, and after blood collection. Absolute CVD risk scores were calculated (Framingham equation) using SBP from each measurement condition and compared.

Results

The prevalence of low (<10%), moderate (10-15%), and high (≥15%) absolute CVD risks among the participants was 67%, 22%, and 11%, respectively, using clinic SBP. SBP values before and during blood collection were significantly higher compared to values after blood collection (130 ± 18 and 132 ± 19 vs. 126 ± 18 mm Hg; p = 0.010 and p = 0.003, respectively). However, there were no significant differences between clinic SBP (128 ± 18 mm Hg) and blood collection SBP (p = 0.99) or the absolute CVD risk scores (7.3 ± 6.5; 7.6 ± 5.9; 7.7 ± 6.1; and 7.1 ± 5.7%, respectively; p = 0.995 for all). The mean intraclass correlation (95% CI) indicated good agreement between absolute CVD risk scores calculated with clinic SBP and each blood collection SBP (0.86 [95% CI 0.74-0.92], 0.85 [95% CI 0.71-0.91], and 0.87 [95% CI 0.76-0.93], respectively; p < 0.001, for all).

Conclusion

Absolute CVD risk calculation is not affected by use of SBP measurements recorded at the time of blood collection. Therefore, it is acceptable to collect blood and measure BP during the same consultation for absolute CVD risk assessment.

Cardiovascular disease risk stratification by the Framigham score is markedly improved by ambulatory compared with office blood pressure

INTRODUCTION AND OBJECTIVES

Ambulatory blood pressure (BP) better predicts cardiovascular disease (CVD) outcomes than office BP measurements (OBPM). Nonetheless, current CVD risk stratification models continue to rely on exclusively daytime OBPM along with traditional factors, eg, age, sex, smoking, dyslipidemia, and/or diabetes.

METHODS

Data from 19 949 participants of the primary care-based Hygia Project assessed by 48-hour ambulatory BP monitoring (ABPM) and without prior CVD events were used to compare the diagnostic accuracy, discrimination, and performance of the original Framingham risk score (RS_OFG) and its adjusted version to the Hygia Project study population (RS_AFG) with that of a novel CVD risk stratification model constructed by replacing OBPM with ABPM-derived prognostic parameters (RS_ABPM).

RESULTS

During the follow-up, lasting up to 12.7 years, 1854 participants experienced a primary CVD outcome of CVD death, myocardial infarction, coronary revascularization, heart failure, stroke, transient ischemic attack, angina pectoris, or peripheral artery disease. Asleep systolic BP (SBP) mean and sleep-time relative SBP decline were the only joint significant ABPM-derived predictive factors of CVD risk and were therefore used to substitute for in-clinic SBP in the RS_ABPM model. The RS_ABPM model, in comparison with the RS_OFG and RS_AFG models, showed significantly improved calibration, diagnostic accuracy, discrimination, and performance (always P<.001). The RS_AFG-derived event-probabilities of 57.3% of the participants were outside the 95% confidence limits of the event probability determined by the RS_ABPM model.

CONCLUSIONS

These collective findings reveal important limitations of CVD risk stratification when based upon OBPM, as in the Framingham score, and corroborate the clinical value of around-the-clock ABPM to properly diagnose true hypertension and reliably stratify CVD vulnerability.

Presence and severity of coronary artery disease in patients who achieved intensive blood pressure reduction at the time of coronary computed tomography angiography

Blood pressure (BP)-lowering treatment should be aimed at achieving intensive BP control. Coronary computed tomography angiography (CCTA) has become more widely available and enables the accurate noninvasive assessment of coronary artery stenosis for screening. The presence and severity of coronary artery disease (CAD) in patients who achieved intensive BP control at the time of CCTA were compared to those in patients without hypertension (HTN). Nine hundred eighty-five consecutive subjects who were clinically suspected of having CAD or who had at least one cardiac risk factor underwent CCTA. The patients were divided into four groups: patients without HTN (non-HTN group), hypertensive patients who underwent intensive BP lowering (intensive group, <130/80 mmHg), patients who underwent standard BP lowering (standard group, 130-139/80-89 mmHg) and patients with uncontrolled BP (uncontrolled group, >140/90 mmHg). Interestingly, %CAD in the Intensive group was significantly higher than that in patients without HTN. The Intensive group was older and had a higher body mass index, more significantly stenosed coronary vessels, lower levels of high-density lipoprotein cholesterol in the blood, and higher rates of dyslipidemia, diabetes, and anti-dyslipidemia and anti-diabetic medication use than the non-HTN group. The presence of CAD in the Intensive group was independently associated with age, male and smoking, whereas the presence of CAD in the non-HTN group was associated with age, male and family history. Finally, predictors of the number of VDs in the non-HTN and intensive BP-lowering groups were age, male, DL, and intensive BP lowering. In conclusion, these results suggest that hypertensive patients need more rigorous management of other coronary risk factors, despite receiving intensive BP-lowering treatment.

Traditional Cardiovascular Risk Factors Strongly Underestimate the 5-Year Occurrence of Cardiovascular Morbidity and Mortality in Spinal Cord Injured Individuals

OBJECTIVES

To explore whether traditional models of cardiovascular disease (CVD) risk prediction correctly predict CVD events across a median 5.7-year follow-up period in individuals with spinal cord injury (SCI) and whether adding SCI-related characteristics (ie, lesion level) to the prediction model can improve the prognostic value.

DESIGN

Retrospective analysis of patient records.

SETTING

Observation at the start of active rehabilitation of participants in a multicenter cohort study, "Restoration of (Wheelchair) Mobility in SCI Rehabilitation," in the Netherlands.

PARTICIPANTS

Patients with SCI (N=200) The patients were 74% men, aged 40±14 years, and with an American Spinal Injury Association (ASIA) impairment score of A through D. Forty percent had tetraplegia, and 69% were motor complete.

INTERVENTIONS

Risk profiling/not applicable.

MAIN OUTCOME MEASURES

Survival status and cardiovascular morbidity and mortality qwere obtained from medical records. Five-year Framingham Risk Scores (FRS) and the FRS ability to predict events assessed using receiver operating characteristic (ROC) curves with corresponding areas under the curve (AUC) and 95% confidence intervals (CI). Kaplan-Meier curves and the log-rank test were used to assess the difference in clinical outcome between participants with an FRS score lower or higher than the median FRS score for the cohort. SCI-related factors associated with CVD events, ASIA impairment, motor completeness, level of injury, and sports participation before injury were explored using univariate and multivariate Cox proportional hazard regression.

RESULTS

The median 5-year FRS was 1.36%. Across a median follow-up period of 5.7 years, 39 developed a CVD event, including 10 fatalities. Although the FRS markedly underestimated the true occurrence of CVD events, the Kaplan-Meier curves and the log-rank test showed that the risk ratio for individuals with an FRS score less than the median FRS (eg, low risk) versus a score greater than the median FRS (high risk) was 3.2 (95% CI, 1.6-6.5; P=.001). Moreover, ROC with corresponding AUCs suggests acceptable accuracy of the FRS to identify individuals with increased risk for future CVD events (ROC AUC of 0.71; 95% CI, 0.62-0.82). Adding ASIA impairment (0.74; 95% CI, 0.66-0.82), motor impairment (0.74; 95% CI, 0.66-0.83), level of injury (0.72; 95% CI, 0.63-0.81), or active engagement in sport before injury (0.72; 95% CI, 0.63-0.88) to the FRS did not improve the level of discrimination.

CONCLUSIONS

Our 5.7-year retrospective study reveals that cardiovascular risk factors and risk models markedly underestimate the true risk for CVD events in individuals with SCI. Nonetheless, these markers successfully distinguish between SCI individuals at high versus low risk for future CVD events. Our data may have future clinical implications, both related to (cutoff values of) CVD risk factors, but also for (earlier) prescription of (non)pharmacologic strategies against CVD in SCI individuals.

Risk management in Halal supply chain: an integrated fuzzy Delphi and DEMATEL approach

Purpose

In a globalised environment, market volatility makes risk management an essential component of the supply chain. Similar to conventional supply chains, a Halal supply chain (HSC) is also affected by several factors making it vulnerable to risks. Therefore, the purpose of this study is to identify and analyse the elements of Halal supply chain management (HSCM) and their significant risk dimensions.

Design/methodology/approach

In total, 72 risk elements of HSCM are identified through a review of contemporary scientific literature along with news items and official websites related to risk management of conventional supply chain management, HSC and sustainable supply chain. Further, 42 risk elements are finalised using fuzzy Delphi and then these risk elements are categorised into 7 dimensions. The interrelationships among the risk dimensions as well as risk elements are developed using fuzzy DEMATEL.

Findings

Results suggest that production, planning, logistic & outsourcing and information technology-related risk are prominent risk dimensions. The causal relationships among the significant risk dimensions and elements related to the HSCM may help managers and policy planners.

Research limitations/implications

This study faces a challenge due to inadequate availability of the literature related to risk management in the area of HSCM. Further, this study has used inputs from experts, which can be biased.

Originality/value

To the best of the author's knowledge, it is the first comprehensive study towards investigating the interrelationships among the risks in the context of the HSCM.

Development and Evaluation of an Educational Program for Community Pharmacists on Cardiovascular Risk Assessment

Purpose

Cardiovascular disease (CVD) risk assessment is an important strategy for the prevention of CVD. Pharmacists play an important role in CVD risk assessment and management (CVDRAM). Our previous study identified gaps in knowledge among community pharmacists for the provision of CVDRAM services as assessed through patient simulation. Therefore, our objectives were: a) to develop and evaluate an educational program on CVD risk assessment for community pharmacists, b) to assess the knowledge and skills of participating pharmacists in assessing and managing CVD risk before and after enrolling in the educational program and c) to explore pharmacists’ satisfaction and perceived effectiveness of the educational program.

Methods

Using a blended learning instructional approach, the educational program for a subset of 25 community pharmacists recruited from our previous study consisted of two face-to-face workshops, and an online 5-module course on CVD risk factors such as hyperlipidemia, hypertension, diabetes, obesity, and smoking cessation based on principles of adult learning. A repeated measures study design was utilized by measuring participants’ knowledge on pre- and post-questionnaires and an objective structured clinical examination (OSCE) at the conclusion of the educational program was also used to assess its impact on the knowledge and skills of community pharmacists in the provision of CVD risk assessment and management (CVDRAM) services. The knowledge questionnaire was completed by 23 pharmacists while the OSCE was completed by 8 pharmacists. In addition, a survey assessed the pharmacists’ level of satisfaction with the educational program.

Results

At the conclusion of the educational program, the participating pharmacists achieved knowledge and skills for the provision of CVDRAM services. Knowledge scores in relation to CVDRAM significantly improved after the educational program [out of a maximum of 20 points, the median (interquartile range) = 9 (7–9) at pre- vs 12 (12–13) at post-educational program], p<0.001. On the OSCE, the median (interquartile range) scores for Stations 1 and 2 were 66 (63–71) and 71 (67–76), respectively. Out of the 21 pharmacists that completed the satisfaction survey, 71% were very satisfied and 29% were satisfied with the educational program.

Conclusion

The educational program improved pharmacists’ knowledge and skills for the provision of CVDRAM services.

Low-density lipoprotein receptor-related protein 1 deficiency in cardiomyocytes reduces susceptibility to insulin resistance and obesity

BACKGROUND

Low-density lipoprotein receptor-related protein 1 (LRP1) plays a key role in fatty acid metabolism and glucose homeostasis. In the context of dyslipemia, LRP1 is upregulated in the heart. Our aim was to evaluate the impact of cardiomyocyte LRP1 deficiency on high fat diet (HFD)-induced cardiac and metabolic alterations, and to explore the potential mechanisms involved.

METHODS

We used TnT-iCre transgenic mice with thoroughly tested suitability to delete genes exclusively in cardiomyocytes to generate an experimental mouse model with conditional Lrp1 deficiency in cardiomyocytes (TNT-iCre⁺-LRP1^flox/flox).

FINDINGS

Mice with Lrp1-deficient cardiomyocytes (cm-Lrp1^-/-) have a normal cardiac function combined with a favorable metabolic phenotype against HFD-induced glucose intolerance and obesity. Glucose intolerance protection was linked to higher hepatic fatty acid oxidation (FAO), lower liver steatosis and increased whole-body energy expenditure. Proteomic studies of the heart revealed decreased levels of cardiac pro-atrial natriuretic peptide (pro-ANP), which was parallel to higher ANP circulating levels. cm-Lrp1^-/- mice showed ANP signaling activation that was linked to increased fatty acid (FA) uptake and increased AMPK/ ACC phosphorylation in the liver. Natriuretic peptide receptor A (NPR-A) antagonist completely abolished ANP signaling and metabolic protection in cm-Lrp1^-/- mice.

CONCLUSIONS

These results indicate that an ANP-dependent axis controlled by cardiac LRP1 levels modulates AMPK activity in the liver, energy homeostasis and whole-body metabolism.
