Heart Rate is Related to Diastolic Blood Pressure

AIM: Recent studies renewed, often neglected interest in association of heart rate (HR), hypertension and cardiovascular morbidity. Our aim was to investigate the relationship of HR and blood pressure (BP) in general population. METHODS: Out of 1375 subjects enrolled in the epidemiologic survey conducted in Croatian rural area, 495 untreated subjects (216 men and 279 women) were included into the study. Exclusion criteria were: antihypertensive therapy, acute illness, chronic terminal disease and serious disability, dementia and pregnancy. BP and HR were measured three times in a sitting position using OMRON device, and mean values were calculated. Subjects were classified into groups with optimal BP (<120/80 mmHg), prehypertension (120/80-140/90 mmHg) and hypertension (>140/90mmHg). Systolic and dyastolic BP values were also observed as continuous variables. RESULTS: Median age of the whole group was 45 (range 19–90). Although statistical significance was not revealed regarding BP categories and quartiles of HR (p=0.365), lower values were observed in subjects with optimal BP compared to values obtained in the hypertensive group. Statistical significance in HR was found between prehypertensive and hypertensive groups (76.44±11.48, and 78.96±12.56 respectively ; p=0.04). Linear regression analysis between HR and BP showed no significance (p=0.360). Significant correlation was found only between diastolic BP and HR (p=0.006) what was also confirmed by the multiple regression analysis (p=0.0073) CONCLUSION:Significant corellation between dyastolic BP and HR was found. Although we could not find statistical significance, our study suggest a trend of increased HR in hypertensive subjects comparing to those with prehypertension.
