Prospective registry of percutaneous coronary interventions: Tyumen Cardiology Center’s experience

Objective. The aim of the study was to evaluate the efficacy and safety of percutaneous coronary interventions (PCI) and to identify the factors impacting long-term prognosis. Methods. The register included 1018 patients who underwent PCI at Tyumen Cardiology Center from October 2012 to November 2013. Results. Hospital cardiovascular mortality rate was 0.8%, while that at 1-year follow-up amounted to 2%. Mortality was associated with age (OR = 1.005; 95% CI 1.003-1.103; p = 0.037), left ventricular ejection fraction (OR = 0.91; 95% CI 0.86-0.96; p = 0.001), left anterior descending artery lesions (OR = 4.73; 95% CI 1.06-21.04; p = 0.042), success of PCI (OR = 0.07; 95% CI 0.02-0.35; p = 0.001), hypodynamia (OR = 5.99; 95% CI 1.78-20.2; p = 0.004) and a low level of social support (OR = 0.41; 95% CI 0.20-0 82; p = 0.012). Main adverse cardio-cerebral events (MACCE) were associated with the history of coronary artery bypass grafting (OR = 0.08; 95% CI 0.01-0.62; p = 0.016), PCI (OR = 1.66; 95 % CI 1.06-2.62; p = 0.028), SYNTAX score (OR = 1.07; 95% CI 1.04-1.09; p <0.001), success of PCI (OR = 0.33; 95% CI 0.13-0.82; p = 0.017). Conclusion. PCI is a safe and effective procedure for treatment of coronary heart disease, which results in low MACCE and mortality rates.
