| Summary: | Background: Cardiovascular diseases are the main cause of death globally. Individuals with evidence of coronary artery disease are at increased risk of further cardiovascular events. However, with good secondary prevention, which consists broadly of lifestyle changes, medical therapy and revascularisation, this risk can be reduced. The true extent of secondary prevention in individuals who are re-admitted with a myocardial infarction in such a high-risk cohort has never been explored in Malaysia. Methods: We performed a retrospective, observational study in a tertiary hospital in 100 individuals with previously diagnosed coronary artery disease admitted with a myocardial infarction from August 2016 to February 2017. Results: Twenty-nine per cent of patients were still smoking; 15% and 47% were not taking antiplatelet or beta-blocker therapy, respectively. A further 45% and 20% of patients were not on any renin-angiotensin-aldosterone inhibition or lipidlowering therapy, respectively. Conclusion: In our high-risk cohort, secondary prevention practices were sub-optimal. Poor physician-patient communication was frequently listed as a major factor. Simple strategies taken at various levels of care should be implemented and audited to improve these practices. © The Author(s) 2017.
