Evaluating the impact of different diagnostic criteria of metabolic syndrome on the prognosis of patients with ST segment elevation myocardial infarction

Abstract

Metabolic syndrome increases the risk of cardiovascular complications in patients with acute coronary syndrome and is associated with a worse course and prognosis in such patients. In Russian population metabolic syndrome is diagnosed according to the Russian society of cardiology criteria of diagnosis which differs from the Joint Interim Societies (JIS) definition of the metabolic syndrome. In turn these differences may lead to differences in the frequency of diagnosis of metabolic syndrome and in assessing its effect on future prognosis. Accordingly, this study was planned.
Objectives: the purpose of this study was to compare the prevalence of metabolic syndrome diagnosed using both definitions in patients with ST segment elevation myocardial infarction and to determine their impact on the future prognosis in this group of patients.
Results: the study included 112 patients with ST segment elevation myocardial infarction. According to the criteria used for diagnosis of MS, patients were divided in two groups, and differences in the rate of diagnosis MS and its effect on the prognosis were evaluated. MS was more often diagnosed using JIS criteria. Patients with Metabolic syndrome according to the Russian society of cardiology criteria of diagnosis was associated with a significantly higher relative risk of cardiovascular complications and mortality, in comparison to patients with metabolic syndrome according to the JIS criteria.
Conclusion: to assess the results of study MS it is necessary to take into account the possibility of decreasing the frequency of diagnosis of MS with the use of Russian society of cardiology criteria, while patients selected according to these criteria have a worse prognosis compared to patients selected according to JIS criteria.
