Abstract :

Ambulatory blood pressure monitoring (ABPM) correlates better with target organ damage than office blood pressure monitoring. Non dipping status on ABPM, defined as <10% dip in night time BP and is considered as a marker of adverse cardiovascular prognosis. The study evaluated the presence of LV diastolic dysfunction in obese patients and correlates it with DIPPER v/s NON DIPPER status and the prevalence of non–dippers in obese patients. RESULTS: Out of the total 31 patients under study total of 71% (n=28) were found to be dippers. Test of one proportion was used to analyse the significance of proportion of patients with dipper and non–dipper status in the study. The Z statistic came out to be 2.338(95% confidence interval; 52% to85.5%) which was found to be significant at p=0.0194 level of confidence. CONCLUSION: there is a positive correlation between presence of diastolic dysfunction and obesity with non–dipping status on ABPM
