This is a cross sectional study of cardiac function tests (2D ECHO) between normotensive & hypertensive males, done in IGMC Nagpur hypertension clinics. Students’‘t’ test is used to analyse parameters with P value of <0.05 is taken as level of significance. The changes in heart rate are insignificant. Mean values of SBP(systolic blood pressure),DBP(diastolic blood pressure),LVPWT(left ventricular posterior wall thickness), IVST(interventricular septum thickness), LVEDD(left ventricular end diastolic diameter),LVESD(left ventricular end systolic diameter), EDV(end diastolic volume) , ESV(end systolic volume),S.V.(Stroke volume), C.O.(cardiac output)statistically significant increased in all five study groups. There is statistically significant decrease in ejection fraction in all five study groups, but it is within normal limit. Present study shows presence of volume overload in addition to pressure overload (after load) which lead to cardiac failure in hypertensive patients. Present study showed that the ventricular performance was not impaired by hypertrophy as such and when ejection fraction was the only index of ventricular function studied, index remained normal.
