Cross-over Study of Coronary Risk Factors With a Polypill

The European Society of Cardiology indicates that reducing the frequency of administration is the most effective measure to improve therapeutic adherence. Current guidelines recommend with class I and level of evidence A the use of polypills.

A polypill, composed of 100 mg of acetylsalicylic acid and variable doses of atorvastatin and ramipril, is approved for secondary prevention of cardiovascular disease and has also been widely used in primary prevention.

Numerous studies have been carried out focusing on different designs of polypill in cardiovascular prevention to study their efficacy, cost-effectiveness and administration schedule. Specifically, that polypill already has an extensive literature. However, although there are previous studies with a cross-over design with other types of polypill to assess the effects on the control of arterial hypertension and LDL cholesterol, to date there has never been a cross-over design study with the polypill compared to the administration of its components separately in the control of blood pressure, lipid level and level of platelet aggregation.

Patients will be randomized to polypill vs separate components. Each patient will receive a follow-up visit per month for 6 months, of which will be 3 consecutive months with treatment with the polypill in its corresponding dose and the remaining 3 months with the same drugs separately.

Primary objectives: Systolic blood pressure level and LDL cholesterol. Secondary objectives: Degree of platelet aggregation with thromboxane A2 kit, diastolic blood pressure level, total cholesterol and HDL, level of patient satisfaction, degree of adherence to treatment, adverse events.

Exclusion criteria

Patients who do not sign the informed consent. Patients with an inability to understand and comply with the protocol. Patients with contraindication to any component of the polypill. Patients who are already participating in another clinical trial. Patients with any condition that limits life expectancy to <1 year. Patients with programmed coronary revascularization. Patients with coronary stent implantation in the last 12 months. Patients treated with any antithrombotic drug in addition to acetylsalicylic acid, that is, low molecular weight heparin, P2Y12 receptor inhibitors, or oral anticoagulants.
