Comparison of Components of Metabolic Syndrome in Premature Myocardial Infarction in an Iranian Population: A Case-Control Study

Background: metabolic syndrome is a major risk factor for coronaryartery disease (cad).aim: aim of this study was to determine the prevalence of metabolicsyndrome in patients with premature myocardial infarction (before50 years of age).methods: in this case–control study, we compared 98 consecutivepatients who were hospitalized in birjand with acute first myocardialinfarction before the age of 50 years and 98 age? and sex?matched healthycontrols without a history of coronary artery disease. the case andcontrol groups were categorized according to the national cholesteroleducation program adult treatment panel (ncep atp iii) metabolicsyndrome criteria [presence of ?3 of the following: fasting blood glucose?100 mg/dl, triglyceride (tg) level ?150 mg/dl, low high densitylipoprotein (hdl; < 40 mg/dl in men and < 50 mg/dl in women),blood pressure ?130/85 mm hg, and waist circumference > 102 cm inmen or 88 cm in women]. the data were collected and analyzed by t?test,?², and logistic regression in spss software 11.5.results: prevalence of metabolic syndrome was significantly higher incases than in control group (34.7% in cases, 16.3% in controls, p=0.003).all components of metabolic syndrome except high waist circumstancein the cases group were significantly higher than in control. the mostcommon component of metabolic syndrome was high tg and the leastcommon component was low hdl.conclusion: we conclude that prevalence of metabolic syndrome inpatients with premature myocardial infarction is high; high tg is themost common component of metabolic syndrome.
