Abstract

Objective: Many studies report that the components of the metabolic syndrome--arterial hypertension, abdominal obesity, diabetes mellitus, and atherogenic dyslipidemia--are associated with an increased risk of cardiovascular disease. We investigated the prevalence of different components of the metabolic syndrome and frequency of their combinations and acute hyperglycemia among patients with acute coronary syndromes.

Methods and results: The study population consisted of 2756 patients (1670 men and 1086 women with a mean age of 63.3+/-11.3 years) with acute coronary syndromes: Q-wave myocardial infarction was present in 41.8% of patients; non-Q-wave MI, in 30.7%; and unstable angina pectoris, in 27.5%. The metabolic syndrome was found in 59.6% of the patients according to modified NCEP III guidelines. One component of the metabolic syndrome was found in 13.5% of patients; two, in 23.0%; and none, in 3.9%. Less than one-third (29.2%) of the patients had three components of the metabolic syndrome, and 30.4% of the patients had four or five components. Arterial hypertension and abdominal obesity were the most common components of the metabolic syndrome (82.2% and 65.8%, respectively). Nearly half of the patients had hypertriglyceridemia and decreased level of high-density lipoprotein cholesterol (55.0% and 51.1%, respectively), and 23.9% of patients had diabetes mellitus. Acute hyperglycemia (> or =6.1 mmol/L) without known diabetes mellitus was found in 38.1% of cases. The combination of arterial hypertension and abdominal obesity was reported in 57.8% of patients in the case of combinations of two-five metabolic syndrome components.

Conclusion: More than half of patients with acute coronary syndromes had three or more components of the metabolic syndrome, and arterial hypertension and abdominal obesity were the most prevalent components of the metabolic syndrome.
