Study of Risk factors for Acute Myocardial Infarction among patients registered at shahid Sadooghi hospital in Yazd: a case - control study

Ischemic heart disease is the most important cause of mortality in many places around the world. Premature heart attacks at early ages are increasing, so identifying and controlling risk factors can be an effective step in public health promotion. This study aimed to investigate the factors affecting on this disease. This is a case-control study conducted on 100 patients with acute myocardial infarction admitted to the CCU and 100 patients hospitalized in other sectors (as a control) in Shahid Sadooghi hospital, Yazd,Iran. The control group was matched for age, sex and risk factors such as smoking, hyperlipidemia, hypertension, diabetes, depression, stress, eating fast food, fruit and vegetable consumption, positive family history and salty food. Then items were examined. Statistical significant level was considered as 95%. The results showed that the crude odds ratio for some factors like smoking (OR=2.22 P=.007), greater stress (OR=3.35 P=.000), depression (OR=3.07 P=.001), high triglycerides (OR=1.86 P=.03), high cholesterol (OR= 3.3 P=.000), high LDL (OR=4.88 P=.000) and high HDL (OR=.041 P=.000) is statistically significant, but the adjusted odds ratio determined that only three factors such as depression (OR = 3.09 P.033), high LDL (OR=6.33 P=.004) and high HDL (OR=.021 P=.000) have major impact on acute myocardial infarction. The results of this study indicated that some modifiable factors such as depression, high LDL and high HDL play a role in causing or preventing acute myocardial infarction. Therefore, controlling these factors can be crucial in controlling the disease.
