Clinical and psychological factors in coronary heart disease patients with statin associated muscle side-effects

Background

To compare clinical and psychological factors among patients with self-perceived statin-associated muscle symptoms (SAMS), confirmed SAMS, and refuted SAMS in coronary heart disease patients (CHD).

Methods

Data were obtained from a cross-sectional study of 1100 CHD outpatients and a study of 71 CHD outpatients attending a randomized, double-blinded, placebo-controlled, crossover study to test effects of atorvastatin 40 mg/day on muscle symptom intensity. Clinical and psychosocial factors were compared between patients with and without SAMS in the cross-sectional study, and between patients with confirmed SAMS and refuted SAMS in the randomized study.

Results

Bilateral, symmetric muscle symptoms in the lower extremities during statin treatment were more prevalent in patients with confirmed SAMS compared to patients with refuted SAMS (75% vs. 41%, p = 0.01) in the randomized study. No significant differences in psychological factors (anxiety, depression, worry, insomnia, type D personality characteristics) were detected between patients with and without self-perceived SAMS in the cross-sectional study, or between patients with confirmed SAMS and refuted SAMS, in the randomized study.

Conclusions

Patients with confirmed SAMS more often present with bilateral lower muscle symptoms compared to those with refuted SAMS. Psychological factors were not associated with self-perceived SAMS or confirmed SAMS. A careful pain history and a search for alternative causes of muscle symptoms are likely to promote communication in patients with SAMS, and may reduce the risk for statin discontinuation.

Effect of atorvastatin on muscle symptoms in coronary heart disease patients with self-perceived statin muscle side effects: a randomized, double-blinded crossover trial

AIMS

To estimate the effect of atorvastatin on muscle symptom intensity in coronary heart disease (CHD) patients with self-perceived statin-associated muscle symptoms (SAMS) and to determine the relationship to blood levels of atorvastatin and/or metabolites.

METHODS AND RESULTS

A randomized multi-centre trial consecutively identified 982 patients with previous or ongoing atorvastatin treatment after a CHD event. Of these, 97 (9.9%) reported SAMS and 77 were randomized to 7-week double-blinded treatment with atorvastatin 40 mg/day and placebo in a crossover design. The primary outcome was the individual mean difference in muscle symptom intensity between the treatment periods, measured by visual-analogue scale (VAS) scores. Atorvastatin did not affect the intensity of muscle symptoms among 71 patients who completed the trial. Mean VAS difference (statin-placebo) was 0.31 (95% CI: -0.24 to 0.86). The proportion with more muscle symptoms during placebo than atorvastatin was 17% (n = 12), 55% (n = 39) had the same muscle symptom intensity during both treatment periods whereas 28% (n = 20) had more symptoms during atorvastatin than placebo (confirmed SAMS). There were no differences in clinical or pharmacogenetic characteristics between these groups. The levels of atorvastatin and/or metabolites did not correlate to muscle symptom intensity among patients with confirmed SAMS (Spearman's rho ≤0.40, for all variables).

CONCLUSION

Re-challenge with high-intensity atorvastatin did not affect the intensity of muscle symptoms in CHD patients with self-perceived SAMS during previous atorvastatin therapy. There was no relationship between muscle symptoms and the systemic exposure to atorvastatin and/or its metabolites. The findings encourage an informed discussion to elucidate other causes of muscle complaints and continued statin use.

The relationship between directly measured statin adherence, self-reported adherence measures and cholesterol levels in patients with coronary heart disease

BACKGROUND AND AIMS

We aimed to determine the relationship between statin adherence measured directly, and by self-report measures and serum cholesterol levels.

METHODS

Patients prescribed atorvastatin (N = 373) participated in a cross-sectional study 2-36 months after a coronary event. Self-reported adherence included statin adherence the past week, the 8-item Morisky medication adherence scale (MMAS-8), and the Gehi et al. adherence question. Atorvastatin was measured directly in spot blood plasma by a novel liquid chromatography tandem mass-spectrometry method discriminating adherence (0-1 doses omitted) and reduced adherence (≥2 doses omitted). Participants were unaware of the atorvastatin analyses at study participation.

RESULTS

Mean age was 63 (SD 9) years and 8% had reduced atorvastatin adherence according to the direct method. In patients classified with reduced adherence by the direct method, 40% reported reduced statin adherence, 32% reported reduced adherence with the MMAS-8 and 22% with the Gehi question. In those adherent by the direct method, 96% also reported high statin adherence, 95% reported high adherence on the MMAS-8 whereas 94% reported high adherence on the Gehi question. Cohen's kappa agreement score with the direct method was 0.4 for self-reported statin adherence, 0.3 for the Gehi question and 0.2 for the MMAS-8. Adherence determined by the direct method, self-reported statin adherence last week, and the Gehi question was inversely related to LDL-cholesterol levels with a p-value of <0.001, 0.001 and 0.004, respectively.

CONCLUSIONS

Plasma-statin measurements reveal reduced adherence with higher sensitivity than self-report measures, relate to cholesterol levels, and may prove to be a useful tool to improve lipid management.

Background

Statin discontinuation due to self-perceived muscle side-effects is a major challenge in clinical practice. Strategies are needed to improve lipid control in these patients.

Purpose

We studied if information about the results of a blinded statin challenge experiment, followed by tailored lipid lowering treatment, had long-term effects on lipid control in coronary patients with self-perceived muscle side-effects.

Methods

A post-trial intervention study of patients classified with statin dependent (N = 20) and independent (N = 50) muscle complaints in the MUscle Side-Effects of atorvastatin (MUSE), a randomized, double-blinded, crossover trial. All participants were informed of the MUSE trial results in an individual consultation and provided tailored lipid-lowering treatment according to protocol with 1-2 follow-up calls. Lipids were controlled at the end of follow-up.

Results

Mean age was 64 (SD 9.5) years and 33% (N = 23) were females. During an average follow-up of 13 months (SD 3.3), mean LDL-cholesterol was reduced by 0.3 (SD 0.6) mmol/L (p = 0.005) in patients with statins and by 1.7 (SD 1.0) mmol/L (p = 0.005) in patients without statins at inclusion in the MUSE trial (Table). We found no changes in the overall use of high-intensity statins, but ezetimibe was used by 11 additional patients and 4 patients were prescribed a PCSK9-inhibitor. Participants in the subgroup without statins at inclusion used; atorvastatin (N = 2), rosuvastatin (N = 3) or a PCSK9-inhibitor (N = 2) at follow-up. 90% found their own trial results useful in making decisions about future statin use.

Conclusions

Information about the results of a statin challenge experiment combined with tailored and systematical prescription of lipid-lowering agents had favourable long-term effects on lipid control in coronary patients with self-perceived muscle side-effects.

Cardiac rehabilitation uptake in ESC member countries: heterogeneity and obstacles

Funding Acknowledgements

Type of funding sources: None.

Introduction

Cardiac Rehabilitation (CR) is a multidisciplinary intervention with proved results in patients with cardiovascular (CV) disease. CR penetration status and implementation strategies differ among ESC various members, with different uptake performance according to the results from the latest Overview of CR in ESC member countries (OCRE) report.

Purpose

To analyse possible implementation factors influencing differential CR phase II uptake after myocardial infarction across OCRE countries. 

Methods

An online survey was sent to all National CV Prevention Coordinators of 51 ESC member countries (champion physicians with deep understanding of their national CR state and easy access to all CR centres for information), to cover important CR demographic, structural and quality control topics. Chi-Square test of independence was performed to find possible statistical associations among surveyed topics with reported average post-MI uptake rate per country.

Results

Forty-two ESC-affiliated countries answered the survey (82% participation rate): 57% were from the South (n = 24); 62% high income countries, 24% upper middle, 14% lower middle, as defined by the ESC Atlas; 65% (n = 28) followed ESC related guidelines. CR uptake was reported at 0-25% (n = 17), 25-50% (n = 14), 50-75% (n = 7), 75-100% (n = 4).

There was a significant correlation between geographic localization and CR patient enrolment, with Northern countries having a higher rate of uptake [X2 (3, n = 42) p = 0,012]. Country wealth did not correlate with CR uptake, but patient low socio-economic status per se, reported as an obstacle by 50% of all countries, showed a positive correlation trend with lower CR enrolment [X2 (3, N = 42), p = 0,07]. A positive association trend between CR predominantly funded by public means and uptake rate was also noted [X2 (3, N = 42), p = 0,08]. Other factors, such as in or outpatient CR delivery predominance or coordination of the program by a cardiologist did not influence the uptake rate. Forty-one percent of the countries reported lack of preventive culture as an obstacle at healthcare level and 16% of them stated cultural issues at patient-level, although no distinct correlation with CR uptake was shown.

Conclusions

Our analysis shows regional differences between Northern and Southern countries in terms of CR uptake following myocardial infarction. The positive exploratory correlation trends may suggest that social/cultural/financial aspects may play a role in the uptake asymmetries. Specifically powered studies and interaction analysis should be sought in the future concerning those variables in particular.

High but not low self-reported statin adherence was confirmed by a novel method based on plasma-statin measurements in coronary outpatients

Funding Acknowledgements

Type of funding sources: Public hospital(s). Main funding source(s): Helse Sør-Øst

Background

To what extent self-reported adherence measures correspond with directly measured statin adherence is unknown.

Purpose

 To determine the relationship between, self-reported adherence measures, low density lipoprotein-cholesterol (LDL-C) and directly measured statin adherence in coronary outpatients.

Methods

Patients on atorvastatin (N = 373) participated in a cross-sectional study median 16 months after a coronary event. Adherence to statins the past 7 days, general medication adherence assessed by the 8-item Morisky medication adherence scale (MMAS-8), and the Gehi adherence question was obtained by a self-report questionnaire. Atorvastatin was determined in spot blood plasma samples by a novel liquid-chromatography tandem mass-spectrometry method discriminating between adherence (0-1 doses omitted) and reduced (≥2 doses omitted) adherence. Participants were unaware of the atorvastatin analyses at study participation. 

Results

Mean age was 63 (SD 9) years and 19% were females. Mean atorvastatin dose was 64 (SD 21) mg. The number with reduced adherence by the different measurement methods, Cohens kappa agreement score between the self-reported and direct adherence measures, and LDL-C are shown in the Table. Statin adherence was confirmed by the direct method among 96% reporting high statin adherence the past 7 days, among 95% reporting high adherence on the MMAS-8 and among 94% reporting high adherence on the Gehi adherence question. In contrast, among patients classified with reduced statin adherence by the direct method, only 40% reported reduced statin adherence the past week, 32% reported reduced adherence with the MMAS-8 and 22% with the Gehi adherence question.

Conclusions

The direct method confirmed high, but not low, self-reported statin adherence in this selected sample of coronary outpatients. In patients with elevated LDL-cholesterol, plasma-statin measurements emerges as a potential improvement for clinical statin management.

Challenges in coronary heart disease prevention - experiences from a long-term follow-up study in Norway

Objective. To determine longitudinal changes in lifestyle behaviour and lipid management in a chronic coronary heart disease (CHD) population. Design. A multi-centre cohort study consecutively included 1127 patients at baseline in 2014-2015, on average 16 months after a CHD event. Data were collected from hospital records, a questionnaire and clinical examination. Seven hundred and seven of 1021 eligible patients participated in a questionnaire-based follow-up in 2019. Data were analysed with univariate statistics. Results. After a mean follow-up of 4.7 years (SD 0.4) from baseline, the percentage of current smokers (15% versus 16%), obesity (23% versus 25%) and clinically significant symptoms of anxiety (21% versus 17%) and depression (13% versus 14%) remained unchanged, whereas the proportion with low physical activity increased from 53% to 58% (p < .001). The proportions with reduced physical activity level were similar in patients over and under 70 years of age. Most patients were still taking statins (94% versus 92%) and more patients used high-intensity statin (49% versus 54%, p < .001) and ezetimibe (5% versus 15%, p < .001) at follow-up. 73% reported ≥1 primary-care consultation(s) for CHD during the last year while 27% reported no such follow-up. There were more smokers among participants not attending primary-care consultations compared to those attending (19% versus 14%, p = .026). No differences were found for other risk factors. Conclusions. We found persistent suboptimal risk factor control in coronary outpatients during long-term follow-up. Closer follow-up and intensified risk management including lifestyle and psychological health are needed to improved secondary prevention and outcome of CHD.

Optimising implementation of European guidelines on cardiovascular disease prevention in clinical practice: what is needed?

Cardiovascular disease is a model example of a preventable condition for which practice guidelines are particularly important. In 2016, the joint task force created by the European Society of Cardiology (ESC) together with 10 other societies released the new version of the European guidelines on cardiovascular disease prevention. To facilitate the implementation of the ESC guidelines, a dedicated prevention implementation committee has been established within the European Association of Preventive Cardiology. The paper will first explore potential barriers to the guidelines’ implementation. It then develops a discussion that seeks to inform the future development of the committee’s work, including a new definition of the guidelines’ stakeholders (health policy-makers, healthcare professionals and health educators, patient organisations, entrepreneurs and the general public), future activities within four specific areas: strengthening awareness of the guidelines among stakeholders; supporting organisational changes to facilitate the guidelines’ implementation; motivating stakeholders to utilise the guidelines; and present ideas on new implementation strategies. Providing multifaceted cooperation between healthcare professionals, healthcare management executives and health policy-makers, the novel approach proposed in this paper should contribute to a wider use of the 2016 ESC guidelines and produce desired effects of less cardiovascular disease morbidity and mortality. Furthermore, the solutions presented within the paper may constitute a benchmark for the implementation of practice guidelines in other medical disciplines.

Preventable clinical and psychosocial factors predicted two out of three recurrent cardiovascular events in a coronary population

BACKGROUND

The relative importance of lifestyle, medical and psychosocial factors on the risk of recurrent major cardiovascular (CV) events (MACE) in coronary patients' needs to be identified. The main objective of this study is to estimate the association between potentially preventable factors on MACE in an outpatient coronary population from routine clinical practice.

METHODS

This prospective follow-up study of recurrent MACE, determine the predictive impact of risk factors and a wide range of relevant co-factors recorded at baseline. The baseline study included 1127 consecutive patients 2-36 months after myocardial infarction (MI) and/or revascularization procedure. The primary composite endpoint of recurrent MACE defined as CV death, hospitalization due to MI, revascularization, stroke/transitory ischemic attacks or heart failure was obtained from hospital records. Data were analysed using cox proportional hazard regression, stratified by prior coronary events before the index event.

RESULTS

During a mean follow-up of 4.2 years from study inclusion (mean time from index event to end of study 5.7 years), 364 MACE occurred in 240 patients (21, 95% confidence interval: 19 to 24%), of which 39 were CV deaths. In multi-adjusted analyses, the strongest predictor of MACE was not taking statins (Relative risk [RR] 2.13), succeeded by physical inactivity (RR 1.73), peripheral artery disease (RR 1.73), chronic kidney failure (RR 1.52), former smoking (RR 1.46) and higher Hospital Anxiety and Depression Scale-Depression subscale score (RR 1.04 per unit increase). Preventable and potentially modifiable factors addressed accounted for 66% (95% confidence interval: 49 to 77%) of the risk for recurrent events. The major contributions were smoking, low physical activity, not taking statins, not participating in cardiac rehabilitation and diabetes.

CONCLUSIONS

Coronary patients were at high risk of recurrent MACE. Potentially preventable clinical and psychosocial factors predicted two out of three MACE, which is why these factors should be targeted in coronary populations.

P4398Potentially modifiable clinical and psychosocial factors associated with recurrent cardiovascular events in an outpatient coronary population

Background

Regular assessment and management of lifestyle, biological and psychosocial factors are recommended in coronary patients. The relative importance of these factors on risk of recurrent cardiovascular (CV) events in the outpatient coronary population is not well known.

Purpose

To estimate the relative effect of potentially modifiable risk factors on recurrent CV events in coronary patients from routine clinical practice.

Methods

A prospective cohort multicenter study from Norway included 1127 (21% women, 83% participation rate) consecutive patients aged 18–80 years 2–36 (mean 16) months after myocardial infarction and/or a coronary revascularization procedure. Thirty percent had at least one coronary event prior to the index event. The primary composite endpoint of recurrent major adverse CV events (MACE): myocardial infarction, revascularization, stroke, heart failure or cardiovascular death was obtained from the hospital records. Cox proportional hazard models stratified for 1 vs. 2+ previous coronary events were performed with model 1 adjusting for age and model 2 with add-on for coronary risk factors and CV comorbidity.

Results

At baseline 99% used platelet inhibition, 93% were taking antihypertensive agents and statins, and 45% had participated in cardiac rehabilitation (CR). During follow-up of mean 4.2 (SD 0.3) years, a total of 355 MACE occurred in 240 patients corresponding to a MACE risk of 31.5%. In model 1, smoking, insufficient physical activity, diabetes, not taking statin therapy, no participation in CR, peripheral artery disease (PAD), previous stroke, kidney failure and higher anxiety and depression scores were significantly associated with recurrent MACE (Table). In model 2, smoking, no physical activity, not taking statin, PAD, kidney failure, anxiety and depression remained significant.

Conclusions

Coronary patients in routine clinical practice were at significant risk of recurrent MACE, particularly in the presence of CV comorbidity. Not taking statin therapy, insufficient physical activity, smoking, anxiety and depression were the major potentially modifiable factors contributing to CV risk. Preventive efforts that target these factors are required to further reduce CV risk in the coronary population.

Managing patients with prediabetes and type 2 diabetes after coronary events: individual tailoring needed - a cross-sectional study

BACKGROUND

Understanding the determinants associated with prediabetes and type 2 diabetes in coronary patients may help to individualize treatment and modelling interventions. We sought to identify sociodemographic, medical and psychosocial factors associated with normal blood glucose (HbA1c < 5.7%), prediabetes (HbA1c 5.7-6.4%), and type 2 diabetes.

METHODS

A cross-sectional explorative study applied regression analyses to investigate the factors associated with glycaemic status and control (HbA_1c level) in 1083 patients with myocardial infarction and/or a coronary revascularization procedure. Data were collected from hospital records at the index event and from a self-report questionnaire and clinical examination with blood samples at 2-36 months follow-up.

RESULTS

In all, 23% had type 2 diabetes, 44% had prediabetes, and 33% had normal blood glucose at follow-up. In adjusted analyses, type 2 diabetes was associated with larger waist circumference (Odds Ratio 1.03 per 1.0 cm, p = 0.001), hypertension (Odds Ratio 2.7, p < 0.001), lower high-density lipoprotein cholesterol (Odds Ratio 0.3 per1.0 mmol/L, p = 0.002) and insomnia (Odds Ratio 2.0, p = 0.002). In adjusted analyses, prediabetes was associated with smoking (Odds Ratio 3.3, p = 0.001), hypertension (Odds Ratio 1.5, p = 0.03), and non-participation in cardiac rehabilitation (Odds Ratio 1.7, p = 0.003). In patients with type 2 diabetes, a higher HbA_1c level was associated with ethnic minority background (standardized beta [β] 0.19, p = 0.005) and low drug adherence (β 0.17, p = 0.01). In patients with prediabetes or normal blood glucose, a higher HbA_1c was associated with larger waist circumference (β 0.13, p < 0.001), smoking (β 0.18, p < 0.001), hypertension (β 0.08, p = 0.04), older age (β 0.16, p < 0.001), and non-participation in cardiac rehabilitation (β 0.11, p = 0.005).

CONCLUSIONS

Along with obesity and hypertension, insomnia and low drug adherence were the major modifiable factors associated with type 2 diabetes, whereas smoking and non-participation in cardiac rehabilitation were the factors associated with prediabetes. Further research on the effect of individual tailoring, addressing the reported significant predictors of failure, is needed to improve glycaemic control.

Optimal blood pressure control after coronary events: the challenge remains

We identified sociodemographic, medical, and psychosocial factors associated with unfavorable blood pressure (BP) control in 1012 patients, hospitalized with myocardial infarction and/or a coronary revascularization procedure. This cross-sectional study collected data from hospital records, a comprehensive self-report questionnaire, clinical examination, and blood samples after 2-36 (mean 17) months follow-up. Forty-six percent had unfavorable BP control (≥140/90 [80 in diabetics] mm Hg) at follow-up. Low socioeconomic status and psychosocial factors did not predict unfavorable BP control. Patients with unfavorable BP used on average 1.9 (standard deviation 1.1) BP-lowering drugs at hospital discharge, and the proportion of patients treated with angiotensin inhibitors and beta-blockers decreased significantly (P < .001) from discharge to follow-up. Diabetes (odds ratio [OR] 2.4), higher body mass index (OR 1.05 per 1.0 kg/m²), and older age (OR 1.04 per year) were significantly associated with unfavorable BP control in adjusted analyses. Only age (standardized beta [β] 0.24) and body mass index (β 0.07) were associated with systolic BP in linear analyses. We conclude that BP control was insufficient after coronary events and associated with obesity and diabetes. Prescription of BP-lowering drugs in hypertensive patients seems suboptimal. Overweight and intensified drug treatment thus emerge as the major factors to target to improve BP control.

Medical and psychosocial factors and unfavourable low-density lipoprotein cholesterol control in coronary patients

Objective Understanding the determinants of low-density lipoprotein cholesterol (LDL-C) control constitutes the basis of modelling interventions for optimal lipid control and prognosis. We aim to identify medical and psychosocial (study) factors associated with unfavourable LDL-C control in coronary patients. Methods A cross-sectional explorative study used logistic and linear regression analysis to investigate the association between study factors and LDL-C in 1095 patients, hospitalized with myocardial infarction and/or a coronary revascularization procedure. Data were collected from hospital records, a comprehensive self-report questionnaire, clinical examination and blood samples after 2-36 months follow-up. Results Fifty-seven per cent did not reach the LDL-C target of 1.8 mmol/l at follow-up. Low socioeconomic status and psychosocial factors were not associated with failure to reach the LDL-C target. Statin specific side-effects (odds ratio 3.23), low statin adherence (odds ratio 3.07), coronary artery by-pass graft operation as index treatment (odds ratio 1.95), ≥ 1 coronary event prior to the index event (odds ratio 1.81), female gender (odds ratio 1.80), moderate- or low-intensity statin therapy (odds ratio 1.62) and eating fish < 3 times/week (odds ratio 1.56) were statistically significantly associated with failure to reach the LDL-C target, in adjusted analyses. Only side-effects (standardized β 0.180), low statin adherence ( β 0.209) and moderate- or low-intensity statin therapy ( β 0.228) were associated with LDL-C in continuous analyses. Conclusions Statin specific side-effects, low statin adherence and moderate- or low-intensity statin therapy were the major factors associated with unfavourable LDL-C control. Interventions to improve LDL-C should ensure adherence and prescription of sufficiently potent statins, and address side-effects appropriately.

An evaluation of the performance of SCORE Sweden 2015 in estimating cardiovascular risk

Background

Risk prediction models for cardiovascular death are important for providing advice on lifestyle and in decision-making regarding primary preventive drug treatment. The latest Swedish version of the Systematic COronary Risk Evaluation (SCORE 2015) has yet not been tested in the population.

Objective

The objective of this study was to estimate the prevalence of high and very high risk of fatal cardiovascular disease (CVD) of the current population according to 2015 SCORE Sweden and to evaluate the predictive accuracy of the 2003 Swedish version of SCORE (2003 SCORE Sweden) and 2015 SCORE Sweden in a population with declining CVD mortality.

Methods

We estimated the high and very high risk group for cardiovascular death for individuals 40–65 years of age in the 2014 Northern Sweden MONICA population survey excluding subjects with known diabetes or previous CVD ( n = 813). Using the 1999 MONICA survey ( n = 3347) followed up for 10 years for CVD mortality, we assessed the calibration of both 2003 and 2015 SCORE Sweden.

Results

In 2014 2.6% of the population was considered at high or very high risk for fatal CVD, 95% were men and 76% were in the age group 60–65 years. Including subjects with a single markedly elevated risk factor, known diabetes or CVD, 12% of the population was at high or very high risk. During 10 years of follow-up of the 1999 cohort, 34 CVD deaths (24 men and 10 women) occurred. The 2003 SCORE overestimated the risk of death from CVD (ratio predicted/observed 2.3, P < 0.001) whereas the 2015 SCORE slightly overestimated the number of deaths (predicted/observed 1.3, P = 0.12). The 2015 SCORE predicted more accurately than the 2003 SCORE the number of deaths in the different risk and age categories.

Conclusion

The 2015 SCORE Sweden more adequately than 2003 SCORE Sweden predicts the number of deaths. In 2014, the proportion of high-risk individuals is small in northern Sweden. The main use of 2015 SCORE Sweden would therefore be as an educational tool between the physician and people without diabetes or CVD in a consultation regarding cardiovascular risk.

Physical activity for primary and secondary prevention. Position paper of the Working Group on Cardiac Rehabilitation and Exercise Physiology of the European Society of Cardiology

There is now clear scientific evidence linking regular aerobic physical activity to a significant cardiovascular risk reduction, and a sedentary lifestyle is currently considered one of the five major risk factors for cardiovascular disease. In the European Union, available data seem to indicate that less than 50% of the citizens are involved in regular aerobic leisure-time and/or occupational physical activity, and that the observed increasing prevalence of obesity is associated with a sedentary lifestyle. It seems reasonable therefore to provide institutions, health services, and individuals with information able to implement effective strategies for the adoption of a physically active lifestyle and for helping people to effectively incorporate physical activity into their daily life both in the primary and the secondary prevention settings. This paper summarizes the available scientific evidence dealing with the relationship between physical activity and cardiovascular health in primary and secondary prevention, and focuses on the preventive effects of aerobic physical activity, whose health benefits have been extensively documented.

Lack of control of hypertension in primary cardiovascular disease prevention in Europe: Results from the EURIKA study

BACKGROUND

The prevalence of and factors associated with uncontrolled hypertension and apparent resistant hypertension were assessed in the European Study on Cardiovascular Risk Prevention and Management in Usual Daily Practice (EURIKA; NCT00882336).

METHODS

EURIKA was a cross-sectional observational study including patients being treated for the primary prevention of cardiovascular disease in 12 European countries. Patients were assessed if they were being treated for hypertension (N=5220). Blood pressure control was defined according to European guidelines, with sensitivity analysis taking account of patients' age and diabetes status. Associated factors were assessed using multivariate analysis.

RESULTS

In the primary analysis, a total of 2691 patients (51.6%) had uncontrolled hypertension. Factors significantly associated with an increased risk of having uncontrolled hypertension included female sex (odds ratio [OR]: 2.29; 95% confidence interval [CI]: 1.93-2.73), body mass index (BMI; OR per kg/m(2): 1.03; 95% CI: 1.01-1.04), and geographic location. A total of 749 patients (14.3%) had apparent resistant hypertension. Factors significantly associated with an increased risk of having apparent resistant hypertension included BMI (OR per kg/m(2): 1.06; 95% CI: 1.04-1.08), diabetes (OR: 1.28; 95% CI: 1.06-1.53), use of statins (OR: 1.36; 95% CI: 1.15-1.62), serum uric acid levels (OR: 1.16; 95% CI: 1.09-1.23), and geographic location. Similar results were seen in sensitivity analyses.

CONCLUSIONS

Over 50% of patients treated for hypertension continued to have uncontrolled blood pressure and 14.3% had apparent resistant hypertension. Positive associations were seen with other cardiovascular risk factors.

A systematic review of studies in the contributions of the work environment to ischaemic heart disease development

BACKGROUND

There is need for an updated systematic review of associations between occupational exposures and ischaemic heart disease (IHD), using the GRADE system.

METHODS

INCLUSION CRITERIA

(i) publication in English in peer-reviewed journal between 1985 and 2014, (ii) quantified relationship between occupational exposure (psychosocial, organizational, physical and other ergonomic job factors) and IHD outcome, (iii) cohort studies with at least 1000 participants or comparable case-control studies with at least 50 + 50 participants, (iv) assessments of exposure and outcome at baseline as well as at follow-up and (v) gender and age analysis. Relevance and quality were assessed using predefined criteria. Level of evidence was then assessed using the GRADE system. Consistency of findings was examined for a number of confounders. Possible publication bias was discussed.

RESULTS

Ninety-six articles of high or medium high scientific quality were finally included. There was moderately strong evidence (grade 3 out of 4) for a relationship between job strain and small decision latitude on one hand and IHD incidence on the other hand. Limited evidence (grade 2) was found for iso-strain, pressing work, effort-reward imbalance, low support, lack of justice, lack of skill discretion, insecure employment, night work, long working week and noise in relation to IHD. No difference between men and women with regard to the effect of adverse job conditions on IHD incidence.

CONCLUSIONS

There is scientific evidence that employees, both men and women, who report specific occupational exposures, such as low decision latitude, job strain or noise, have an increased incidence of IHD.

Low rates of both lipid-lowering therapy use and achievement of low-density lipoprotein cholesterol targets in individuals at high-risk for cardiovascular disease across Europe

AIMS

To analyse the treatment and control of dyslipidaemia in patients at high and very high cardiovascular risk being treated for the primary prevention of cardiovascular disease (CVD) in Europe.

METHODS AND RESULTS

Data were assessed from the European Study on Cardiovascular Risk Prevention and Management in Usual Daily Practice (EURIKA, ClinicalTrials.gov identifier: NCT00882336), which included a randomly sampled population of primary CVD prevention patients from 12 European countries (n = 7641). Patients' 10-year risk of CVD-related mortality was calculated using the Systematic Coronary Risk Evaluation (SCORE) algorithm, identifying 5019 patients at high cardiovascular risk (SCORE ≥5% and/or receiving lipid-lowering therapy), and 2970 patients at very high cardiovascular risk (SCORE ≥10% or with diabetes mellitus). Among high-risk individuals, 65.3% were receiving lipid-lowering therapy, and 61.3% of treated patients had uncontrolled low-density lipoprotein cholesterol (LDL-C) levels (≥2.5 mmol/L). For very-high-risk patients (uncontrolled LDL-C levels defined as ≥1.8 mmol/L) these figures were 49.5% and 82.9%, respectively. Excess 10-year risk of CVD-related mortality (according to SCORE) attributable to lack of control of dyslipidaemia was estimated to be 0.72% and 1.61% among high-risk and very-high-risk patients, respectively. Among high-risk individuals with uncontrolled LDL-C levels, only 8.7% were receiving a high-intensity statin (atorvastatin ≥40 mg/day or rosuvastatin ≥20 mg/day). Among very-high-risk patients, this figure was 8.4%.

CONCLUSIONS

There is a considerable opportunity for improvement in rates of lipid-lowering therapy use and achievement of lipid-level targets in high-risk and very-high-risk patients being treated for primary CVD prevention in Europe.

The MacNew Heart Disease Health-Related Quality of Life Questionnaire: A Scandinavian Validation Study

The aim of this study is to validate the Danish, Norwegian and Swedish versions of the self-administered MacNew Heart Disease Health-related Quality of Life questionnaire in patients with ischemic heart disease. The MacNew questionnaire, the Short Form SF-36, and the Hospital Anxiety and Depression Scale were completed at baseline by 976 patients (Denmark n = 353, Norway n = 328, Sweden n = 295) with a diagnosis of angina (n = 335), myocardial infarction (n = 352), or heart failure (n = 289). Each language version of the MacNew satisfied reliability criteria with Cronbach's α values for the total group data (0.90-0.94) as well as the diagnostic group data (0.91-0.96). The test-retest correlations exceeded the criteria for group comparison (r ≥ 0.70) in Danish and Norwegian patients. The multidimensionality of the MacNew was confirmed although the original three-factor solution did not fully meet the criteria for good fit. Convergent and discriminative validity were confirmed in each language and diagnosis group with the exception of discriminative validity in Swedish angina patients. The psychometric properties of the Danish, Norwegian, and Swedish versions of the MacNew are largely confirmed. The MacNew can be recommended as a specific instrument for assessing and evaluating HRQL in Danish, Norwegian, and Swedish patients with angina, MI, and heart failure. However, the MacNew factor structure needs to be revisited in future studies.

Health-related quality of life in European women following myocardial infarction: a cross-sectional study

BACKGROUND

Coronary heart disease is a major contributor to women's health problems.

DESIGN

Self-perceived social support, well-being and health-related quality of life (HRQL) were documented in the cross-sectional HeartQoL survey of European women one and six months after a myocardial infarction.

METHODS

European women were recruited in 18 European countries and grouped into four geographical regions (Southern Europe, Northern Europe, Western Europe and Eastern Europe). Continuous socio-demographic variables and categorical variables were compared by age and region with ANOVA and χ(2), respectively; multiple regression models were used to identify predictors of social support, well-being and HRQL.

RESULTS

Women living in the Eastern European region rated social support, well-being and HRQL significantly lower than women in the other regions. Older women had lower physical HRQL scores than younger women. Eastern European women rated social support, well-being and HRQL significantly lower than women in the other regions. Prediction of the dependent variables (social support, well-being and HRQL) by socio-demographic factors varied by total group, in the older age group, and by region; body mass index and managerial responsibility were the most consistent significant predictors.

C-reactive protein levels in patients at cardiovascular risk: EURIKA study

Background

Elevated C-reactive protein (CRP) levels are associated with high cardiovascular risk, and might identify patients who could benefit from more carefully adapted risk factor management. We have assessed the prevalence of elevated CRP levels in patients with one or more traditional cardiovascular risk factors.

Methods

Data were analysed from the European Study on Cardiovascular Risk Prevention and Management in Usual Daily Practice (EURIKA, ClinicalTrials.gov Identifier: NCT00882336), which included patients (aged ≥50 years) from 12 European countries with at least one traditional cardiovascular risk factor but no history of cardiovascular disease. Analysis was also carried out on the subset of patients without diabetes mellitus who were not receiving statin therapy.

Results

In the overall population, CRP levels were positively correlated with body mass index and glycated haemoglobin levels, and were negatively correlated with high-density lipoprotein cholesterol levels. CRP levels were also higher in women, those at higher traditionally estimated cardiovascular risk and those with greater numbers of metabolic syndrome markers. Among patients without diabetes mellitus who were not receiving statin therapy, approximately 30% had CRP levels ≥3 mg/L, and approximately 50% had CRP levels ≥2 mg/L, including those at intermediate levels of traditionally estimated cardiovascular risk.

Conclusions

CRP levels are elevated in a large proportion of patients with at least one cardiovascular risk factor, without diabetes mellitus who are not receiving statin therapy, suggesting a higher level of cardiovascular risk than predicted according to conventional risk estimation systems.

Strengths and weaknesses of working with the Global Trigger Tool method for retrospective record review: focus group interviews with team members

OBJECTIVES

The aim was to describe the strengths and weaknesses, from team member perspectives, of working with the Global Trigger Tool (GTT) method of retrospective record review to identify adverse events causing patient harm.

DESIGN

A qualitative, descriptive approach with focus group interviews using content analysis.

SETTING

5 Swedish hospitals in 2011.

PARTICIPANTS

5 GTT teams, with 5 physicians and 11 registered nurses.

INTERVENTION

5 focus group interviews were carried out with the five teams. Interviews were taped and transcribed verbatim.

RESULTS

8 categories emerged relating to the strengths and weaknesses of the GTT method. The categories found were: Usefulness of the GTT, Application of the GTT, Triggers, Preventability of harm, Team composition, Team tasks, Team members' knowledge development and Documentation. Gradually, changes in the methodology were made by the teams, for example, the teams reported how the registered nurses divided up the charts into two sets, each being read respectively. The teams described the method as important and well functioning. Not only the most important, but also the most difficult, was the task of bringing the results back to the clinic. The teams found it easier to discuss findings at their own clinics.

CONCLUSIONS

The GTT method functions well for identifying adverse events and is strengthened by its adaptability to different specialties. However, small, gradual methodological changes together with continuingly developed expertise and adaption to looking at harm from a patient's perspective may contribute to large differences in assessment over time.
