Cardiovascular reactivity has been identified as potentially playing a role in the development of cardiovascular disease. It can be used as a non-intensive method to identify the preclinical state of the cardiovascular disease. However , many studies on cardiovascular reactivity in normotensive young adults with family history of hypertension showed incosistent and controversial results. The objective of the studyis to find out if normotensive young adults with family history of hypertension have inceased cardiovascular reactivity to mental aritmetic test and cold pressors test as compared to normotensive yougn adults without family history of hypertension. Normotensive undergraduate students, aged 20-30 years of hypertensive parents and of normotensive parents performed mental arithmetic test and cold pressor test. Cardiovascular parameters were recorded before , during and after the test with automated oscillometric device. Delta change score rather than absolute score were analyzed. There were no significant differences in age , body mass index, fasting blood sugar and plasma creatinine level between the two groups.
