Аннотация
BACKGROUND: Cardiovascular diseases (CVDs) are the leading cause of death in Iran. A fixed-dose combination therapy (polypill) was proposed as a cost-effective strategy for CVD prevention, especially in lower-resource settings. We conducted the PolyPars trial to assess the effectiveness and safety of polypill for prevention of CVD.
METHODS: The PolyPars trial is a pragmatic cluster randomized controlled trial nested within the Pars Cohort Study. Participants were randomized to an intervention arm and a control arm. Participants in the control arm received minimal non-pharmacological care, while those in the intervention arm received polypill in addition to minimal care. The polypill comprises hydrochlorothiazide 12.5 mg, aspirin 81 mg, atorvastatin 20 mg, and either enalapril 5 mg or valsartan 40 mg. The primary outcome of the study is defined as the first occurrence of acute coronary syndrome (non-fatal myocardial infarction and unstable angina), fatal myocardial infarction, sudden cardiac death, new-onset heart failure, coronary artery revascularization procedures, transient ischemic attack, cerebrovascular accidents (fatal or non-fatal), and hospitalization due to any of the mentioned conditions. The secondary outcomes of the study include adverse events, compliance, non-cardiovascular mortality, changes in blood pressure, fasting blood sugar, and lipids after five years of follow-up.
RESULTS: From December 2014 to December 2015, 4415 participants (91 clusters) were recruited. Of those, 2200 were in the polypill arm and 2215 in the minimal care arm. The study is ongoing. This trial was registered with ClinicalTrials.gov number NCT03459560.
CONCLUSION: Polypill may be effective for primary prevention of CVDs in developing countries.
