Abstract
OBJECTIVES: Physical inactivity is associated with high cardiovascular risk. The purpose of this study was to study physical activity levels of patients with acute coronary syndrome (ACS). METHODOLOGY: A total of 504 patients, from the Professorial Unit of the Colombo South Teaching Hospital completed the International Physical Activity Questionnaire (IPAQ). IPAQ is a validated questionnaire used internationally to objectively measure physical activity. Both the total volume and the number of sessions of activity are included in the IPAQ. Populations are divided into three levels based on physical activity levels: low, moderate and high activity. RESULTS: Out of 504 patients, 128 (25.1%) were highly active, 87 (17.1%) were minimally active and 289 (56.7%) were found be inactive. When considering mets per week 134 (26.3%) spent less than 1000mets/week. Physical activity levels of men and women were similar (p=0.06). There was a no significant association between body mass index (BMI) with total IPAQ score (p=0.11). There was no difference in the physical activity levels of patients presenting with different types of ACS: ST-Elevation Myocardial Infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI) or unstable angina (UA) (p=0.36). The activity levels did not affect the severity of ACS assessed by Thrombolysis In Myocardial Infarction (TIMI) scores. (NSTEMI/UA p=0.24, STEMI p=0.10). CONCLUSION: In Sri Lanka, a majority of patients with ACS were physically inactive. Physical inactivity is one of the remediable major risk factors of ACS and an active life style should be promoted.
