Medication adherence, biological and lifestyle risk factors in patients with myocardial infarction: a ten-year follow-up on socially differentiated cardiac rehabilitation.

Objective: There is strong evidence that medication adherence and lifestyle changes are essential in patients undergoing secondary cardiovascular disease prevention. Cardiac rehabilitation (CR) increases medication adherence and improves lifestyle changes. Patients with cardiac diseases and a low educational level and patients with little social support are less responsive to improve medication adherence and to adapt lifestyle changes. The aim of the present study was to investigate the long-term effects of a socially differentiated CR intervention on medication adherence as well as changes in biological and lifestyle risk factors at two- five- and ten-year follow-up. Design: A prospective cohort study. Setting: The cardiac ward at Aarhus University Hospital, Denmark. Intervention: A socially differentiated CR intervention in addition to the standard CR program. Subjects: Patients admitted with first-episode myocardial infarction between 2000 and 2004, N = 379. Patients were defined as socially vulnerable or non-socially vulnerable according to their educational level and extent of social network. Main outcome measures: Primary outcome was medication adherence to antithrombotics, beta-blockers, statins and angiotensin-converting enzyme inhibitors. Secondary outcomes were biological and lifestyle risk factors defined as; total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, glycated hemoglobin, blood pressure and smoking status. Results: No significant long-term effect of the intervention was found. Conclusions: The results indicate a non-significant effect of the intervention. However, it was found that equality in health was improved in the study population except concerning smoking. General practitioners manage to support the long-term secondary cardiovascular disease prevention in all patients regardless of social status. Key points The socially differentiated intervention did not significantly improve medication adherence or biological and lifestyle risk factors. Despite the non-significant effect of the intervention, equality in health was improved except concerning smoking. General practitioners managed to support the long-term secondary cardiovascular disease prevention in all patients regardless of social status.

Does socially differentiated cardiac rehabilitation affect the use of healthcare services after myocardial infarction? A 10-year follow-up study.

OBJECTIVE: To examine the long-term effect of a socially differentiated cardiac rehabilitation (CR) intervention tailored to reduce social inequalities in health regarding use of healthcare services in general practice and hospital among socially vulnerable patients admitted with first-episode myocardial infarction (MI). DESIGN: A prospective cohort study with 10 years' follow-up. SETTING: Department of cardiology at a university hospital in Denmark between 2000 and 2004. PARTICIPANTS: Patients <70 years admitted with first-episode MI categorised as socially vulnerable (n=208) or non-socially vulnerable (n=171) based on educational level and social network. INTERVENTION: A socially differentiated CR intervention. The intervention consisted of standard CR and expanded CR with focus on cross-sectional collaboration. MAIN OUTCOME MEASURES: Participation in annual chronic care consultations in general practice, contacts to general practice, all-cause hospitalisations and cardiovascular readmissions. RESULTS: At 2-year and 5-year follow-up, socially vulnerable patients receiving expanded CR participated significantly more in annual chronic care consultations (p=0.02 and p<0.01) but at 10-year follow-up, there were no significant differences in annual chronic care consultations (p=0.13). At 10-year follow-up, socially vulnerable patients receiving standard CR had significantly more contacts to general practice (p=0.03). At 10-year follow-up, there were no significant differences in the proportion of socially vulnerable patients receiving expanded CR in the mean number of all-cause hospitalisations and cardiovascular readmissions (p>0.05). CONCLUSIONS: The present study found no persistent association between the socially differentiated CR intervention and use of healthcare services in general practice and hospital in patients admitted with first-episode MI during a 10-year follow-up.

Expanded cardiac rehabilitation in socially vulnerable patients with myocardial infarction: a 10-year follow-up study focusing on mortality and non-fatal events.

OBJECTIVE: Cardiac rehabilitation (CR) has been shown to reduce cardiovascular risk. A research project performed at a university hospital in Denmark offered an expanded CR intervention to socially vulnerable patients. One-year follow-up showed significant improvements concerning medicine compliance, lipid profile, blood pressure and body mass index when compared with socially vulnerable patients receiving standard CR. The aim of the study was to perform a long-term follow-up on the socially differentiated CR intervention and examine the impact of the intervention on all-cause mortality, cardiovascular mortality, non-fatal recurrent events and major cardiac events (MACE) 10 years after. DESIGN: Prospective cohort study. SETTING: The cardiac ward at a university hospital in Denmark from 2000 to 2004. PARTICIPANTS: 379 patients aged <70 years admitted with first episode myocardial infarction (MI). The patients were defined as socially vulnerable or non-socially vulnerable according to their educational level and their social network. A complete follow-up was achieved. INTERVENTION: A socially differentiated CR intervention. The intervention consisted of standard CR and additionally a longer phase II course, more consultations, telephone follow-up and a better handover to phase III CR in the municipal sector, in general practice and in the patient association. MAIN OUTCOME MEASURES: All-cause mortality, cardiovascular mortality, non-fatal recurrent events and MACE. RESULTS: There was no significant difference in all-cause mortality (OR: 1.29, 95% CI 0.58 to 2,89), cardiovascular mortality (OR: 0.80, 95% CI 0.31 to 2.09), non-fatal recurrent events (OR:1.62, 95% CI 0.67 to 3.92) or MACE (OR: 1.31, 95% CI 0.53 to 2.42) measured at 10-year follow-up when comparing the expanded CR intervention to standard CR. CONCLUSIONS: Despite the significant results of the socially differentiated CR intervention at 1-year follow-up, no long-term effects were seen regarding the main outcome measures at 10-year follow-up. Future research should focus on why it is not possible to lower the mortality and morbidity significantly among socially vulnerable patients admitted with first episode MI.

Effectiveness of expanded cardiac rehabilitation in patients diagnosed with coronary heart disease: a systematic review protocol.

REVIEW OBJECTIVE/QUESTION: The objective of this review is to identify the effectiveness of expanded cardiac rehabilitation (CR) in patients diagnosed with coronary heart disease (CHD). Specifically, the review question is: What is the effectiveness of expanded CR compared to standard CR in adult patients diagnosed with CHD? Effectiveness will be assessed by the effect on mortality and readmissions due to all causes or any cardiac event, systolic blood pressure, cholesterol levels and adherence to recommendations in secondary prevention guidelines.
