The Role of Anthropometric Parameters and Physical Activity Level in Patients with Acute Coronary Syndrome Admitted to the Intensive Cardiac Care Unit

Anthropometric parameters have a role in diagnosing obesity, which increases the risk of acute coronary syndrome (ACS). The aim of the study was to assess the impact of obesity and physical activity level on the severity and long-term prognosis of ACS. A total of 116 patients with ACS were analyzed according to baseline (demography, medical history, anthropometry), severity (clinical presentation, in-hospital complications, laboratory, echocardiography, coronary angiography) and prognostic parameters (major adverse cardiovascular events during a six-year period). The levels of obesity and physical activity (Baecke/Lipid Research Clinics physical activity questionnaires) were compared with a sample of the Croatian general population. Study results showed the subjects with a higher number of narrowed coronary arteries (CAs) to have higher body mass index (BMI) and waist circumference (WC); those with stenosed left anterior descending artery and anterior myocardial infarction (MI) had higher BMI; waist-to-hip ratio (WHR) positively correlated with creatine kinase and negatively with left ventricle ejection fraction (p<0.05). Inactive patients more often had multivessel coronary disease and anterior MI; patients with a higher leisure physical activity index had a lower number of affected CAs, lower rate of stent implantations and lower stent length, while those with a higher work physical activity index had a lower rate of anterior MI (p<0.05). During the follow- up, inactive patients had more strokes and deaths (p<0.05). Our patients had higher body weight, WC and WHR, as well as lower leisure time and total physical activity indices than the general population (p
