Introduction: Metabolic syndrome (Met. S.) is an association of multiple cardiovascular risk factors which consists of insulin resistance, diabetes or impaired glucose metabolism, central obesity, hypertriglyceridemia and low level of high-density lipoprotein cholesterol (HDL-C), in addition to hypertension. Objective: The aim of the present work is to study the effect of different components of Met. S. on right ventricular volume and function. Methods: This case control study had been conducted in cardiology department at Zagazig university hospitals. This study included 60participants, 30 cases and 30 controls. Results: This case control study had been conducted in cardiology department at Zagazig university hospitals. Total number of subjects was 60 divided in to two groups: Group1- 30 patients with established components of Met. S.. Group2-30 controls. The Met. S. was defined by the presence of three or more criteria of the National Cholesterol Education Program's Adult Treatment Panel III (NCEPATP-III). Conclusion: The effects of the components of metabolic syndrome on RV volume and function was evident in clinical and subclinical RV dysfunction. TAPSE and myocardial performance index Tei. index are good reliable methods for evaluation of RV function.
