Risk factors for acute myocardial infarction as seen in coronary care unit, Farwania hospital in Kuwait

ABSTRACT

In order to assess the hazard ratio of serum cholesterol concentration, hypertension, diabetes mellitus and smoking as risk factors for acute myocardial infarction associated solely with males, a case-control study was carried out on 252 male patients admitted with acute myocardial infarction on the coronary care unit [CCU], Farwania Hospital in 1986. Two hundred and fifty-two males of similar age were seen in the medical outpatient department [MOPD] who had functional dyspepsia during 1986. Being proved to be free of heart disease, they were studied as a control group. We found that the hazard ratios of acute myocardial infarction with respect to risk factors were as follows for serum cholesterol above 6.5 mmol/L versus below 5.2 mmol/L, 9.95 [99% confidence limit 3.86 to 25.61]; for blood pressure in the highest quintile, 2,01 [99% confidence limit 1.15 to 3.49]; for smoking 10 or more cigarettes daily versus never smoking 2.26[99% confidence limit 1.43 to 3.56]; for diabetics versus non-diabetics, 1.74 [99% confidence limit 1.04 to 2.92]
