Abstract: Metabolic Syndrome (MetS) is a group of clinical disorders, is widespread and correlated with elevated cardiovascular morbidity and mortality. Total 300 subjects with metabolic syndrome according to the Harmonized criteria underwent 2D echo and Doppler imaging in the present prospective, observational cohort study. Present study demonstrated the high prevalence of diastolic dysfunction with metabolic syndrome in asymptomatic subjects. About three-fourth of the subjects with metabolic syndrome had diastolic dysfunction. A historical factor in the worsening of diastolic function is the increasing age, high prevalence of diastolic dysfunction in middle-aged patients with metabolic syndrome, highlighting the need for timely recognition and early intervention before the development of diastolic heart failure in these patients.
