EFFECT OF COLD PRESSOR TEST ON BLOOD PRESSURE IN SUBJECTS WITH HYPERTENSIVE FIRST DEGREE RELATIVES
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 52
Abstract
BACKGROUND Majority of individuals with essential hypertension and some with usually normal blood pressure manifest unusual lability and marked reaction of blood pressure to various internal and external stimuli. This suggests that mechanism for regulating blood pressure possessed by these individuals is hyperreactive. The aim of the study was to find out effects of hand immersion in cold water (CPT) on blood pressure in subjects with their first-degree relatives who were hypertensive. MATERIALS AND METHODS For convenience, we took total of 300 apparently healthy medical students of both sexes in the age group of 18 to 22 years and comparative study was done in them. Amongst these 150 subjects had their first-degree relation hypertensive and served as experimental group, while remaining 150 did not have any family history of their first-degree relation hypertensive and served as controls. Subjects were asked to immerse their hand up to wrist in cold water (CPT) at 200C and 100C for a period of 30 seconds, during which their blood pressure was recorded. RESULTS Data was collected and was analysed using student’s ‘t’ test and p value of < 0.05 was taken as scientifically significant. On hand immersion in cold water at 200C, both systolic and diastolic blood pressure was increased in both groups. In Control group the increase in systolic blood pressure was just significant compared with basal, while increase in diastolic blood pressure was not statistically significant. In experimental group, both increase in systolic and diastolic pressure was statistically significant compared with basal (P < 0.01). Similarly, on hand immersion in cold water (CPT) at 100C the increase in systolic blood pressure was just significant in control group (P < 0.05), while in experimental group it was highly significant (P < 0.001). CONCLUSION Hand immersion in cold water (CPT) up to wrist at 200C and 100C, there was increase in both systolic and diastolic blood pressure in both the groups.
