Key result
Compliance to secondary prevention strategies among 1,206 CAD patients in South India was moderate, including 93.9% for smoking cessation, 65.1% for BP control, and 36.5% for LDL control.
Why the study?
Data on compliance with secondary prevention strategies for coronary artery disease from resource-limited settings were needed.
Cross-Sectional (n=1,206)
Yes
Compliance to secondary prevention strategies for CAD in resource-limited settings is moderate, highlighting significant gaps in LDL control and physical activity that require targeted interventions.
Low LDL control signals prevention gaps in CAD; leaves open regional drivers pending prospective studies.
OBJECTIVES: The primary objective of the study was to report the compliance to secondary prevention strategies for coronary artery disease (CAD), such as smoking cessation, weight management, low-density lipoprotein (LDL) cholesterol control, blood pressure control, glycaemic control, physical activity and cardiovascular drug therapy from a resource-limited setting. DESIGN: Analytical cross-sectional survey with data collection using questionnaire administered by study personnel. SETTING: Institutional-two tertiary care hospitals and two cardiology clinics. PARTICIPANTS: Patients in the age group of 30-80 years with documented CAD with a minimum of 1 year and a maximum of 6 years of follow-up after diagnosis. MAIN OUTCOME MEASURES: The main outcome measures were the prevalence of individual compliance to secondary prevention strategies for CAD such as smoking cessation, weight management, LDL cholesterol control, blood pressure control, glycaemic control, physical activity and cardiovascular drug therapy. The secondary outcomes were the association of secondary prevention strategies with age, sex, domicile, socioeconomic status, insurance and type of treatment. RESULTS: We recruited a total of 1206 patients among whom 879 (72.9%) were males. The median age of patients was 62 (14) years. The compliance to smoking cessation was 93.86% (95% CI 91.66% to 96.06%), ideal body mass index was 63.76% (95% CI 61.05% to 66.47%), blood pressure control was 65.11% (95% CI 62.42% to 67.80%), LDL compliance was 36.50% (95% CI 33.18% to 39.82%), diabetes control was 51.23% (95% CI 46.10% to 56.36%) and adequate physical activity was 39.22% (95% CI 36.46% to 41.98%)respectively. Reported compliance for cardiovascular drugs therapy was 96% for antiplatelets, 89.4% for statins, 68.2% for beta blockers, 37.7% for renin angiotensin aldosterone system blockers, 81.28% for oral hypoglycaemic agents and 22% for insulin therapy. CONCLUSION: Compliance to secondary prevention strategies for CAD in resource limited settings are moderate. This needs further improvement for better outcomes related to CAD in future.
