Rationale and design of VICAD-RISK study: Visualization of coronary artery disease for modification of risk factors

BACKGROUND

With the increasing use of coronary computed tomography angiography (CTA), the prevalence of patients with nonobstructive atherosclerotic coronary artery disease (NOCAD) is growing. Presence of NOCAD is associated with an increased risk of an unfavorable clinical outcome. Therefore, guideline-directed preventive strategies such as lipid-lowering therapy with statins are important. This study aims to assess whether visualization of personal CTA images to patients with a new diagnosis of NOCAD facilitates reduction of low-density lipoprotein (LDL) cholesterol (primary endpoint), improves statin adherence, influences the perception of statin-associated side effects, and modifies the coronary atherosclerotic phenotype.

METHODS

The VICAD-RISK study is a Danish multicenter randomized trial including statin naïve patients suspected of chronic coronary syndrome with a new diagnosis of NOCAD determined by first-line coronary CTA. A total of 273 patients will be randomized 1:1:1 into; (1) usual care; representing current clinical practice of general practitioner follow-up; (2) low-intensity intervention; specialized nurse consultation, or (3) high-intensity intervention; similar to group 2 and presentation of the personal CTA-images. All participants, including the intervention groups, will be followed at the discretion of their general practitioner. Research follow-up including biochemistry measurements, and coronary CTA investigation will be repeated for all participants after 12 months.

CONCLUSION

The VICAD-RISK study evaluates whether personal CTA image visualization in patients with a new diagnosis of NOCAD improves reduction of LDL cholesterol.

BATF alleviates ox-LDL-induced HCAEC injury by regulating SIRT1 expression in coronary heart disease

BACKGROUND

Coronary heart disease (CHD) represents a significant global health concern, arising from an intricate interplay between genetic predisposition and environmental influences, with a pivotal involvement of oxidized low-density lipoprotein (ox-LDL) in the pathophysiology of it. We aimed to elucidate the synergistic dynamics of B cell activating transcription factor (BATF) and Sirtuin 1 (SIRT1) in cell injury caused by ox-LDL, reveal potential therapeutic strategies for CHD.

METHODS

The GSE42148 dataset was used to analyze Differentially expressed genes (DEGs) to construct a gene co-expression network. Then bioinformatics analysis was performed on key modules to select the BATF gene. In vitro experiments were conducted to investigate the protective impact of BATF against human coronary artery endothelial cells (HCAEC) injury induced by ox-LDL. Further investigations probed the synergistic impact of BATF and SIRT1 modulation on cellular apoptosis and damage in the presence of ox-LDL.

RESULTS

BATF was significantly down-regulated in the CHD sample of the GSE42148 dataset. In vitro assays have proven that BATF alleviates ox-LDL-induced HCAEC injury. Notably, BATF emerged as a pivotal regulator of SIRT1 expression post ox-LDL exposure. Subsequent experiments underscored the interplay between BATF and SIRT1 in mitigating ox-LDL-induced apoptosis and Lactate Dehydrogenase (LDH) activity elevation, highlighting their collaborative role in cellular protection.

CONCLUSION

The research findings suggested a prospective protective function of BATF in HCAEC injury induced by ox-LDL, likely through the mediation of SIRT1 regulation. These results could offer fresh perspectives on the etiology of CHD and possible treatment avenues.

A Global Perspective on Cardiovascular Risk Factors by Educational Level in CHD Patients: SURF CHD II

BACKGROUND

Clinical guidelines recommend lifestyle modifications and medication use to control cardiovascular risk factors in coronary heart disease (CHD) patients. However, risk factor control remains challenging especially in patients with lower educational level.

OBJECTIVE

To assess inequalities by educational level in the secondary prevention of CHD in the Survey of Risk Factors in Coronary Heart Disease (SURF CHD II).

METHODS

SURF CHD II is a cross-sectional clinical audit on secondary prevention of CHD, conducted during routine clinical visits in 29 countries. The easy-to-perform design of the survey facilitates its implementation in settings with limited resources. We reported risk factor recording, attainment of guideline-defined risk factor targets, and treatment in CHD patients. Differences by educational level in target attainment and treatment were assessed with logistic regression stratified for high- (HIC), upper middle- (UMIC), and lower middle-income (LMIC) countries.

RESULTS

SURF CHD II included 13,884 patients from 2019 to 2022, of which 25.0% were female and 18.6% had achieved only primary school level. Risk factor recording ranged from 22.2% for waist circumference to 95.6% for smoking status, and target attainment from 15.9% for waist circumference to 78.7% for smoking. Most patients used cardioprotective medications and 50.5% attended cardiac rehabilitation.Patients with secondary or tertiary education were more likely to meet targets for smoking, LDL cholesterol and physical activity in HICs and LMICs; for physical activity and triglycerides in UMICs; but less likely to meet targets for blood pressure in HICs and LDL <1.4mmol/L in UMICs. Higher education was positively associated with medication use and cardiac rehabilitation participation.

CONCLUSION

CHD patients generally have poor attainment of risk factor targets, but patients with a higher educational level are generally more likely to participate in cardiac rehabilitation, use medication, and meet targets.

MAIN MESSAGES

Target attainment and participation in cardiac rehabilitation are poor in CHD patients globally.Patients with higher education are more likely to meet risk factor targets, showing health inequities in secondary prevention of CHD.The association between education and risk factor target attainment and treatment varies with country income level.

Changes in lipid lowering medication and lipid levels over time in patients with stable coronary artery disease

BACKGROUND/AIM

To provide longitudinal data on the evolution of lipid levels and the intake of lipid-lowering therapies in patients with stable coronary artery disease.

METHODS

Single-centre retrospective study with inclusion of 350 patients with a first coronary artery event in 2014 or earlier and outpatient cardiac clinic follow-up in 2015 and 2019. Lipid levels were collected within a time frame of 3 months of their visits.This retrospective study protocol (2020.086) was approved by the ethical committee and by the Data Privacy Officer of AZ Maria Middelares Ghent. For this type of study, formal consent is not required, following local law and regulations.

RESULTS

Average LDL levels were 82 (±26) mg/dl in 2015 and 70 (±24) mg/dl in 2019 (p < 0.001). Most patients included were already on statin treatment before inclusion in the trial (94%), with a significant increase in high-intensity statin use (45% vs. 58%) after a 5-year follow-up. At the same time, we observed a significant increase in ezetimibe use (in combination with statin therapy or in monotherapy) (8% vs. 22%) during follow-up. LDL ≤70 mg/dl was 34% in 2015 and 53% in 2019. LDL ≤55 mg/dl was 13% in 2015 and 28% in 2019.

CONCLUSION

This study shows significant intensification of lipid-lowering therapy use during follow-up, and a significant lipid level lowering after 5-year follow-up, in an outpatient cardiac clinic follow-up. Further improvement in lipid control is still desirable, especially after the European Society of Cardiology recommend stricter lipid levels in the 2021 Prevention Guidelines.

Prevalence of Cardioprotective Medication Use in Coronary Heart Disease Patients in South America: Systematic review and Meta-Analysis

Background

Coronary heart disease (CHD) is the most common cause of death globally, and clinical guidelines recommend cardioprotective medications for patients with established CHD. Suboptimal use of these medications has been reported, but information from South America is scarce.

Methods

We conducted a systematic review on prevalence of secondary prevention medication in South America. We pooled prevalence estimates, analysed time-trends and guideline compliance, and identified factors associated with medication use with meta-regression models.

Results

73 publications were included. Medication prevalence varied by class: beta-blockers 73.4%(95%CI 66.8%-79.1%), ACEI/ARBs 55.8%(95%CI 49.7%-61.8), antiplatelets 84.6%(95%CI 79.6%-88.5%), aspirin 85.1%(95%CI 79.7%-89.3%) and statins 78.9%(95%CI 71.2%-84.9%). The use of beta-blockers, ACEI/ARBs and statins increased since 1993. Ten publications reported low medication use and nine reported adequate use. Medication use was lower in community, public and rehabilitation settings compared to tertiary centres.

Conclusion

Cardioprotective medication use has increased, but could be further improved particularly in community settings.

European Society of Cardiology Quality Indicators for Cardiovascular Disease Prevention: developed by the Working Group for Cardiovascular Disease Prevention Quality Indicators in collaboration with the European Association for Preventive Cardiology of the European Society of Cardiology

AIMS

To develop a set of quality indicators (QIs) for the evaluation of the care and outcomes for atherosclerotic cardiovascular disease (ASCVD) prevention.

METHODS AND RESULTS

The Quality Indicator Committee of the European Society of Cardiology (ESC) formed the Working Group for Cardiovascular Disease Prevention Quality Indicators in collaboration with Task Force members of the 2021 ESC Guidelines on Cardiovascular Disease Prevention in Clinical Practice and the European Association of Preventive Cardiology (EAPC). We followed the ESC methodology for QI development, which involved (i) the identification of the key domains of care for ASCVD prevention by constructing a conceptual framework of care, (ii) the development of candidate QIs by conducting a systematic review of the literature, (iii) the selection of the final set of QIs using a modified Delphi method, and (iv) the evaluation of the feasibility of the developed QIs. In total, 17 main and 14 secondary QIs were selected across six domains of care for ASCVD prevention: (i) structural framework, (ii) risk assessment, (iii) care for people at risk for ASCVD, (iv) care for patients with established ASCVD, (v) patient education and experience, and (vi) outcomes.

CONCLUSION

We present the 2021 ESC QIs for Cardiovascular Disease Prevention, which have been co-constructed with EAPC using the ESC methodology for QI development. These indicators are supported by evidence from the literature, underpinned by expert consensus and aligned with the 2021 ESC Guidelines on Cardiovascular Disease Prevention in Clinical Practice to offer a mechanism for the evaluation of ASCVD prevention care and outcomes.

Gaps in antihypertensive and statin treatments and benefits of optimisation: a modelling study in a 1 million ethnically diverse urban population in UK

OBJECTIVES

To characterise gaps in antihypertensive treatment in people with hypertension and statin treatment in people with cardiovascular diseases (CVD) in a large urban population and quantify the health and economic impacts of their optimisation.

DESIGN

A cross-sectional population study and a long-term CVD decision model.

SETTING

Primary care, UK.

PARTICIPANTS

All adults with diagnosed hypertension or CVD in a population of about 1 million people, served by 123 primary care practices in London, UK in 2019.

INTERVENTIONS

Following UK clinical guidelines, all adults with diagnosed hypertension were categorised into optimal, suboptimal and untreated groups with respect to their antihypertensive treatment, and all adults with diagnosed CVD were categorised in the same manner with respect to their statin treatment.

OUTCOMES

Proportion of patients suboptimally treated or untreated. Projected cardiovascular events avoided, years and quality-adjusted life years (QALYs) gained and healthcare costs saved with optimised treatments.

RESULTS

21 954 of the 91 828 adults with hypertension (24%; mean age 59 years; 49% women) and 9062 of the 23 723 adults with CVD (38%; mean age 69 years; 43% women) were not optimally treated with antihypertensive or statin treatment, respectively. Per 1000 additional patients optimised over 5 years, hypertension treatment is projected to prevent 25 (95% CI 16 to 32) major vascular events (MVEs) and 7 (3 to 10) vascular deaths, statin treatment, 28 (22 to 33) MVEs and 6 (4 to 7) vascular deaths. Over their lifespan, a patient with uncontrolled hypertension aged 60-69 years is projected to gain 0.64 (95% CI 0.36 to 0.87) QALYs with optimised hypertension treatment, and a similarly aged patient with previous CVD not optimally treated with statin is projected to gain 0.3 (0.24 to 0.37) QALYs with optimised statin treatment. In both cases, the hospital cost savings minus extra medication costs were about £1100 per person over remaining lifespan.

CONCLUSIONS

Optimising cardiovascular treatments can cost-effectively reduce cardiovascular risk and improve life expectancy.

Medical Treatment in Coronary Patients: Is there Still a Gender Gap? Results from European Society of Cardiology EUROASPIRE V Registry

PURPOSE

This study is aimed at investigating gender differences in the medical management of patients with coronary heart disease (CHD).

METHODS

Analyses were based on the ESC EORP EUROASPIRE V (European Survey Of Cardiovascular Disease Prevention And Diabetes) survey. Consecutive patients between 18 and 80 years, hospitalized for a coronary event, were included in the study. Information on cardiovascular medication intake at hospital discharge and at follow-up (≥ 6 months to < 2 years after hospitalization) was collected.

RESULTS

Data was available for 8261 patients (25.8% women). Overall, no gender differences were observed in the prescription and use of cardioprotective medication like aspirin, beta-blockers, and ACE-I/ARBs (P > 0.01) at discharge and follow-up respectively. However, a statistically significant difference was found in the use of statins at follow-up, in disfavor of women (82.8% vs. 77.7%; P < 0.001). In contrast, at follow-up, women were more likely to use diuretics (31.5% vs. 39.5%; P < 0.001) and calcium channel blockers (21.2% vs. 28.8%; P < 0.001), whereas men were more likely to use anticoagulants (8.8% vs. 7.0%; P < 0.001). Overall, no gender differences were found in total daily dose intake (P > 0.01). Furthermore, women were less likely than men to have received a CABG (20.4% vs. 13.2%; P < 0.001) or PCI (82.1% vs. 74.9%; P < 0.001) at follow-up. No gender differences were observed in prescribed (P = 0.10) and attended (P = 0.63) cardiac rehabilitation programs.

CONCLUSION

The EUROASPIRE V results show only limited gender differences in the medical management of CHD patients. Current findings suggest growing awareness about risk in female CHD patients.
