Data, such as age, gender, educational level, employment and clinical status, such as time of diagnosis, CHD family history, smoking status, alcohol consumption, documented cardiac co-morbidities and treatment modalities, were collected from a review of patient records and through patient interview using a structured proforma. Outpatients who did not receive revascularisation therapy (percutaneous
coronary intervention/coronary artery bypass graft) were categorized as receiving medical therapy, in view of their conservative management.
