Adherence To Therapy

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.

Background: The clinical benefits of cytochrome P450 (CYP) 2C19 genotype-guided antiplatelet therapy in Asians remain unclear. In this study, we aimed to investigate the clinical outcomes of pharmacogenomic antiplatelet therapy in Chinese patients.Methods: Patients with acute coronary syndrome planning to undergo percutaneous coronary intervention were eligible for this study and were randomly divided into a genotype-guided treatment (GT) group and routine treatment (RT) group, with a ratio of 2:1. Patients in the GT group underwent CYP2C19 genotyping (*2 and *3 alleles), and the results were considered in selecting P2Y12 receptor inhibitors. Patients in the RT group were treated with P2Y12 receptor inhibitors according to their clinical characteristics. The primary endpoint was a composite of major adverse cardiovascular or cerebrovascular events (MACCE). The secondary endpoint was significant bleeding events.Results: Finally, 301 patients were enrolled; 75.1% were men and the mean age was 59.7 ± 9.8 years. In total, 281 patients completed the follow-up procedure. The primary endpoint occurred in 16 patients, 6 patients in the GT group and 10 in the RT group. The GT group showed lower MACCE rates than the RT group (6/189 vs. 10/92, 3.2 vs. 10.9%, hazard ratio: 0.281, 95% confidence interval: 0.102–0.773, P = 0.009). There was no statistically difference in significant bleeding events between the GT and RT groups (4.2 vs. 3.3%, hazard ratio: 1.315, 95% confidence interval: 0.349–4.956, P = 0.685).Conclusion: Personalized antiplatelet therapy that is based on CYP2C19 genotypes could decrease MACCE within a 12-month period in Chinese patients with acute coronary syndrome undergoing percutaneous coronary intervention.Clinical Trial Registration:http://www.chictr.org.cn, identifier: ChiCTR2000034352.

Compelling evidence from randomized controlled studies have confirmed the efficacy of dual antiplatelet therapy, with aspirin and a P2Y12 inhibitor, in reducing the risk of cardiovascular events particularly among patients with acute coronary syndrome and/or those undergoing percutaneous coronary intervention. They thus represent one of the most frequently prescribed drugs worldwide.
