Abstract

Converting-enzyme inhibition as a guide to the hypotensive response to be expected from surgery was evaluated in 27 hypertensive patients with renovascular disease. Blood pressure averaged 163 +/- 5/102 +/- 2 mm Hg (mean +/- standard error of the mean) during converting-enzyme inhibition with captopril, 518 +/- 29 mg daily for 2.8 +/- 0.3 months, and stabilized at a similar level of 165 +/- 4/104 +/- 3 mm Hg during 5.0 +/- 0.6 months of postoperative follow-up, when no medication was administered. Postoperative pressure, both systolic (r = +0.53; p = 0.004) and diastolic (r = +0.55; p = 0.003), was correlated with blood pressure during converting-enzyme inhibition. In addition, multiple regression analysis identified systolic pressure during converting-enzyme inhibition as the only significant (p less than 0.01) predictor of postoperative systolic pressure. Diastolic pressure during converting-enzyme inhibition (p less than 0.05) in conjunction with circulating renin (p less than 0.05) and renin suppression from the contralateral kidney (p less than 0.01) explained up to 53% of the postoperative diastolic pressure. Therefore, blood pressure during long-term converting-enzyme inhibition may be useful as a predictor of the postop...Continue Reading

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
