Compliance in elderly hypertensives.
Hypertension is common in the elderly. While it is possible to reduce blood pressure in this age group, the value of such treatment in terms of reduced mortality and morbidity is unknown. The effects of a prescribed regimen depends inter alia on compliance. Therefore, this variable must be taken into account in assessing drug treatment in the elderly hypertensive. In general, the elderly comply...
متن کاملCardiovagal Tone: A Predictor of Heart Rate Adjusted Augmentation Index in Men but Not in Women
Purpose: Aortic augmentation index (AIx) and cardiovagal tone (CVT) are indicators of cardiovascular health. Associations between these variables provide information about their roles in cardiovascular disease. However, evaluating these associations from a gender perspective and gaining an understanding of the relationship between cardiorespiratory fitness and AIx based on gender can provide ad...
متن کاملBaroreflex function in elderly hypertensives.
Baroreflex function was assessed in elderly hypertensive patients and compared with that observed in young hypertensives and young normotensives. Mean arterial pressure was reduced by 20% using intravenous nitroprusside infusion in 10 elderly hypertensive patients (older than 65 years and diastolic pressures over 95 mm Hg), in 10 young hypertensives (under 60 years and diastolic pressures over ...
متن کاملIntrinsic stiffness of the carotid arterial wall material in essential hypertensives.
We have previously shown that the decrease in large artery distensibility observed in patients with essential hypertension (HT group) was primarily due to an increase in distending pressure and not to hypertension-associated structural modifications of the artery, suggesting a functional adaptation of the wall material. To evaluate the elastic properties of the wall material of the common carot...
متن کاملQT Interval: Correction for Heart Rate
There are several empirically based proposals in the literature for adjusting QT intervals for heart rate. Two widely used correction formulas are Bazett’s and Fridericia’s. This study examines the general formulation of heart rate correction of QT intervals, and several of the existing adjustments are used with this approach. Simple correction formulas for both populations and individuals have...
