Popis: Introduction: It remains unclear whether cardiac rehabilitation (CR) can enhance adherence to cardiovascular (CV) medications. We aim to determine the impact of CR on 6-month adherence to CV pharmacotherapy. Methods: We conducted a prospective observational cohort study of patients hospitalized for acute coronary syndromes (ACS) in Quebec, Canada, during 2016-2018. The primary endpoint was 6-month adherence to all of these drugs (dual anti-platelets, beta-blockers, hypocholesterolemiants, angiotensin pathway inhibitors). The secondary endpoints were adherence to each individual class of CV medication. Adherence was determined by measuring the proportion of days covered (PDC) (evaluated by pharmacies refills). PDC was measured both as continuous and categorical variables. Suboptimal adherence was defined as PDC< 80%. We used inverse probability weighting to adjust for various factors which may have influenced the referral for CR and confounded the impact of CR on 6-month adherence (age, sex, coronary angioplasty, marital status, education, and occupation). All patients signed informed consent. Results: We enrolled 318 patients. Their mean age was 66±12 years; 30% were females. Of these patients, 152 undertook CR and 166 received standard follow-up. The mean age was 68 and 64 years, respectively. The proportions of females were similar in both groups. Overall PDC were 96%±13% vs 93%±17%; 7.2% and 11.2% patients had 6-month suboptimal adherence, respectively in patients who had CR vs patients without CR. After inverse weighting adjustment, CR was independently associated with improved adherence only with hypocholesterolemiants (Table 1). Conclusion: CR was not associated with improved 6-month overall adherence. However, patients who undertook CR were more adherent to hypocholesterolemiants than patients who did not undergo CR. CR programs should reinforce further to patients the importance of adherence to all ACS medications.
