The essential hypertension is an emerging life style disease and hereditary plays an important role in predisposing essential hypertension. It is a risk factor for many cardiovascular diseases. The present study aimed to compare sympathetic reactivity of Normotensive offsprings of Normotensive parents (NN) and Hypertensive parents (NH). The total 300 Normotensive offsprings were taken for study purpose after taking clearance from institutional committee and written informed consent from participants. Out of these 300 Normotensive offsprings, 60 were from Hypertensive parents (NH) and 240 were from Normotensive parents (NN). All participants were performed sustained isometric contraction for 3 minutes by hand grip dynometer. The heart rates, blood pressure (SBP, DBP) were recorded before and after the exercise. Subjects of Hypertensive parents (NH) showed non-significant effect of exercise while subjects of Normotensive parents (NN) showed a significant change in cardiovascular parameters after exercise. When mean change was compared offspring of Hypertensive parents (NH) showed heart rate (HR) change with significant effect. The present study found a significant effect of family history of hypertension on sympathetic nervous system reactivity. The heart rate is main parameter to predict cardiovascular risk and hypertension in their later life.
