OBJECTIVES The goal of this study is to identify co-morbidities associated with acute myocardial infarction in Tobago. METHODS This was a longitudinal retrospective study of myocardial infarction at the Tobago Regional Hospital in two selected periods: January 2007 to April 2007 and January 2008 to April 2008. Data were retrieved from the patients' medical records. These included co-morbid conditions eg hypertension, diabetes mellitus, dyslipidaemia, ESRD, whether history of smoking or cocaine use and if any prior care. In the former period, 11 cases were confirmed as having myocardial infarction and 27 cases in the latter period. RESULTS In 2007 and 2008, all cases had dyslipidaemia (LDL > 100 mg/dL) and were hypertensive. There were 36.4% of cases in 2007 that had diabetes mellitus, compared to 33.3% cases in 2008 and 9.1% had chronic kidney disease in 2007, compared to 25.9% in 2008.
