Adherence to Medical Treatment in Patients who Have Experienced Acute Coronary Syndrome and Percutaneous Coronary Intervention.

PURPOSE: to study adherence to therapy after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). We analyzed retrospectively 127 case histories of patients who underwent PCI for ACS in 2015 (in Udmurtia at that time PCIs were mostly carried out later than 6 hours after onset of symptoms).

INCLUSION CRITERIA: age 25-75 years; confirmed ACS; stenting of coronary arteries for the first time.

EXCLUSION CRITERIA: pregnancy; prisoners; incompetent persons; history of PCI or coronary artery bypass grafting. In two years after the PCI 95 patients were questioned concerning use of statins (including their doses) and dual antiplatelet therapy (DAPT).

RESULTS: In 2 years after index PCI 83% of patients took statins regularly. DAPT for 1 year or more after PCI received 85% of patients.

CONCLUSION: Adherence to therapy with statins and antiplatelet therapy was found to be high. PCI in patients with ACS was mainly delayed (more than 6 hours from the onset of symptoms). It is necessary to further improve the routing of patients to PCI performing centers from Udmurtia regions for the timely myocardial revascularization.
