Understanding the diurnal variation of blood pressure (BP) is important in the management of hypertension.
Primary objectives of the study were to analyse the pattern of nocturnal BP in patients with essential hypertension who are already on treatment.MethodologyCross-sectional descriptive study was conducted at cardiology unit Teaching Hospital Kandy, in 2015, in patients referred from the hypertensive clinic at Teaching Hospital Peradeniya. A consecutive sample of 100 essential hypertensives aged>18 years with stage I to III hypertension were included. Patients with a history of previous ischemic heart disease or cerebro-vascular events were excluded. Twenty-four-hour ambulatory blood pressure monitoring was performed in all patients after complete clinical evaluation.
Sample size was 100. Mean age was 60.86 ± 8.73 years. Twenty eight were male. In the sample 32 had normal dipping patterns. Out of the 68 with abnormal dipping, 45 had sub-optimal dipping, 19 had reverse dipping and 4 had extreme dipping. There were 72 patients with nocturnal hypertension, of them 29 (39.7%) had isolated nocturnal hypertension.
A high prevalence of abnormal dipping, nocturnal hypertension and isolated nocturnal hypertension among our sample of patients with essential hypertension. Therefore, it is important to increase awareness and to consider ambulatory blood pressure monitoring to detect these abnormal nocturnal blood pressure variations.
