Abstract

Abstract Background Given the ongoing burden of cardiovascular disease and an ageing population, physical activity in patients with coronary artery disease needs to be emphasized. This study assessed whether sedentary behaviour and physical activity levels differed among older patients (≥75 years) following percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) consisting of ST-segment elevation myocardial infarction (STEMI) and non STEMI (NSTEMI) versus an elective admission control group of stable angina patients. Methods Sedentary behaviour and physical activity were assessed over a 7-day period using wrist-worn triaxial accelerometers (GENEActiv, Activinsights Ltd, UK) in 58 patients following PCI for, STEMI (n = 20) NSTEMI (n = 18) and stable angina (n = 20) upon discharge from a tertiary centre. Mean ± Standard deviation age was 79 ± 4 years (31% female). Results STEMI and NSTEMI patients spent more time in the low acceleration category (0–40 mg) reflecting sedentary time versus stable angina patients (1298 ± 59 and 1305 ± 66 vs. 1240 ± 92 min/day, p < 0.05). STEMI and NSTEMI patients spent less time in the 40–80 mg acceleration category reflecting low physical activity versus stable angina patients (95 ± 35 and 94 ± 41 vs. 132 ± 50 min/day, p < 0.05). Stable angina patients spent more time in the higher acceleration categories (80–120 and 120–160 mg) and moderate-to-vigorous physical activity (defined as 1 and 5 min/day bouts) versus NSTEMI patients (p < 0.05). For acceleration categories ≥160 mg, no differences were observed. Conclusions Patients presenting with ACS and undergoing PCI spent more time in sedentary behaviour compared with stable angina patients.
