A study to find out the proportion of prediabetes in patients with acute coronary syndrome in a medical college of Kolkata.

摘要

Prediabetes is now considered as a definite entity for increased incidence of cardiovascular disease and a potent risk for progression to type 2 diabetes mellitus. As macrovascular disease is the commonest cause of increased mortality in dysglycaemic individuals (prediabetes and diabetes) by 2-4 times as opposed to normal individuals, clinicians do encounter patients with cardiovascular disease of varying severity regularly. There are increased constellation of other cardiovascular risk factors (hypertension, dyslipidaemia, etc), in prediabetes as compared to normal population. Here a study was carried out among 62 acute coronary syndrome patients who were admitted in a tertiary care hospital in Kolkata to find out the proportion of prediabetes in them. Majority of the patients (54.8%) were in the age group of 45-64 years and were males (77.4%). The study showed 48.4% of all acute coronary syndrome patients were prediabetic and 25% were diabetic. The proportion of impaired fasting glucose and impaired glucose tolerance were 19.4% and 22.6% respectively. So, altogether 72.4% patients were dysglycaemic. Out of all acute coronary syndrome patients, non-ST elevated myocardial infarction group had 50% prediabetic patients, ST elevated myocardial infarction group had 50% prediabetic patients and unstable angina group have 45.8% prediabetic patients. So, all patients of acute coronary syndrome should be screened to detect hyperglycaemia in early stage to prevent further development of diabetes mellitus and also further cardiovascular events.
