RESUMEN
Oral anticoagulants (OACs) are widely used for prevention of systemic thromboembolism, including the reduction of the risk of stroke in patients with atrial fibrillation (AF) and prosthetic heart valves. There is also an increasing population of patients who require not only OACs, but also double antiplatelet therapy (DAPT). A typical example is a patient with AF and stable coronary artery disease or acute coronary syndrome (ACS), treated by percutaneous coronary intervention. In recent years, with the introduction of NOACs, triple or dual therapy has become safer. Regardless of these indications for the use of NOACs, rivaroxaban at a reduced dose has proved to efficiently reduce the risk of further thrombotic events when added to DAPT in patients who have suffered an ACS. However, such therapy increases the incidence of bleeding complications. Interesting was also the potential impact of the pleiotropic mechanism of action of non-vitamin K antagonist oral anticoagulants (NOACs) through proteaseactivated receptors 1 and 2, present on the platelets and many other cells, and changing the course of arterial atherosclerosis. The COMPASS trial has shown that in the group treated with rivaroxaban combined with aspirin, the primary outcome (cardiovascular death, stroke, and myocardial infarction) occurred significantly less frequently than in the group treated only with aspirin. However, a significantly higher number of bleedings was observed. In the subgroup of patients with peripheral artery disease, a significant reduction of the incidence of amputations was shown. The outcomes of the COMPASS trial might be a breakthrough in the treatment of coronary and peripheral atherosclerosis.

The in-hospital mortality following myocardial infarction has decreased substantially over the last two decades in Poland. However, according to the available evidence approximately every 10th patient discharged after myocardial infarction (MI) dies during next 12 months. We identified the most important barriers (e.g. insufficient risk factors control, insufficient and delayed cardiac rehabilitation, suboptimal pharmacotherapy, delayed complete myocardial revascularisation) and proposed a new nation-wide system of coordinated care after MI. The system should consist of four modules: complete revascularisation, education and rehabilitation programme, electrotherapy (including ICDs and BiVs when appropriate) and periodical cardiac consultations. At first stage the coordinated care programme should last 12 months. The proposal contains also the quality of care assessment based on clinical measures (e.g. risk factors control, rate of complete myocardial revascularisation, etc.) as well as on the rate of cardiovascular events. The wide implementation of the proposed system is expected to decrease one year mortality after MI and allow for better financial resources allocation in Poland.
