Metabolik Sendromlu Hastalarda Sağ Ventrikül Fonksiyonlarının Doku Doppler Ekokardiyografi İle Değerlendirilmesi

Aim: Metabolic syndrome is defined as a clinical entity characterized by insulin resistance, abdominal obesity, glucose intolerance or diabetes mellitus, dyslipidemia and hypertension.  In the present study, we aimed to evaluate right ventricular function in metabolic syndrome patients with tissue Doppler echocardiography. Material and Method: The study population consisted of 28 metabolic syndrome patients and sex-age matched 30 control subjects. All the study population underwent echocardiography and right ventricular function was assessed by tissue echocardiography.   Results: The mean age of the metabolic syndrome patients was 48±6.7 and control group was 46±8.3 and there was no statistical significant difference.  When compared to the control group, right ventricular function assessed by tissue doppler was found to be significantly lower in metabolic syndrome patients (10.3±2.4 vs 16.4±3.6; p<0.001). Besides, early diastolic wave (Em) velocity, one of the important indicator of the diastolic function, was significantly lower in the metabolic syndrome group (8.3±3.1 vs 12.5±4.6; p<0.001).  Late diastolic wave (Am) velocity was found to be comparable between the groups (14.3±5.4 vs 15.7±5.8).   Conclusion: Metabolic syndrome patients with normal left ventricular function had impaired right ventricular function assessed by tissue doppler echocardiography.  Key Words: Metabolik syndrome, Right ventricle, Echocardiography
