Clinical histories of 574 inpatients with acute coronary syndrome in 6 tertiary hospitals were reviewed and the presence of metabolic syndrome and its components determined by applying Adult Treatment Panel III criteria. In a second step, the components of the metabolic syndrome were analyzed, excluding those patients with diabetes mellitus.
The metabolic syndrome was present in 50.9 % of patients and was more frequent in women than in men (66.3 % vs. 47.3 % ; P < .001). The most prevalent component was carbohydrate metabolism disorder (85.3 % ), followed by low high-density lipoprotein cholesterol (HDLc) levels (80.5 % ). In nondiabetic patients, 34.6 % had metabolic syndrome and the most prevalent component was low HDLc levels (86 % ), followed by high blood pressure and hypertriglyceridemia and, in fourth place, impaired fasting serum glucose levels.
The metabolic syndrome has a high prevalence in patients with an acute coronary syndrome, especially in women. The most frequent components are hyperglycemia and low HDLc levels. After excluding diabetic patients, the most prevalent diagnostic criterion of metabolic syndrome was low HDLc levels.
