The impact of coronary stenting on long-term quality of life in patients with stable coronary heart disease

Abstract

The purpose of the work is to assess the impact of percutaneous coronary intervention (PCI) on quality of life (QOL) parameters in patients with stable coronary heart disease (CHD).Material and methods. 175 people with stable CHD were examined, group I consisted of 77 people who underwent PCI for 1 year, group II - 98 patients who did not undergo myocardial revascularization. During the study, all patients underwent general clinical examination, ECG recording in standard 12 leads, echocardiography (ECHOCG), daily ECG monitoring to determine heart rate variability, determination of QOL parameters according to the Ukrainian version of the international questionnaire Medical Outcomes Study Short Form (MOS SF-36).Results. It was established that for patients with stable CHD is characterized by a decrease in all indicators of QOL. No significant difference was found in the parameters of QOL of persons who underwent PCI and patients who were not revascularized. There was a tendency to greater limitation of vital activity due to physical problems in the group of persons without revascularization - (13.9 ± 3.6) points against (22.3 ± 4.9) points in group I, (p = 0.16). The physical status of patients of group I was (44.8 ± 2.8) points, persons of group II - (41.7 ± 2.6) points, p = 0.42. Mental status was in group I (36.8 ± 1.8) points, in group II - (35.1 ± 2.0) points (p = 0.54). The general status of persons who underwent revascularization was (61.6 ± 3.1) points, persons without revascularization - (62.7 ± 3.2) points (p = 0.8). The negative correlation of physical status with the age of patients (r = -0.36), the presence of chronic respiratory diseases (r = -0.41), the presence of ventricular extrasystoles (VE) when recording the ECG (r = -0.25) , as well as the number of VE during the day according to daily monitoring (r = -0.29), the number of paired VE (r = -0.27), the number of episodes of ventricular bigeminy (r = -0.23) and trigeminy (r = -0.26).Conclusions. In persons with stable CHD there is a decrease in physical, mental and general status of QOL according to the questionnaire MOS SF36. The QOL values of patients with stable CHD who underwent PCI during the year do not differ significantly from the parameters of persons who did not undergo revascularization. The physical and mental status of patients with stable CHD is most associated with age, the presence of concomitant chronic pathology, ventricular arrhythmias.
