Abstract

The prevalence of left ventricular hypertrophy (LVH) is higher in elderly patients with hypertension than in normotensive patients. The factors relationed herewith are not well known. The first purpose was to analyse the relationship between the levels of blood pressure (BP) recorded by ambulatory blood pressure monitoring (ABPM) and the left ventricular mass index (LVMI) in a group of untreated patients older than 55 years with essential hypertension. Our second purpose was to observe the relationship between the concentration of several circulating hormones and the left ventricular mass index. The study included 31 untreated patients with mild to moderate essential hypertension and 37 healthy normotensives. Both groups were of similar age, sex and body mass index. We determined for both groups the casual arterial pressure (CAP), ambulatory BP monitoring (ABPM) throughout 24 h, daytime (07.00-23.00 h), nighttime (23.00-07.00 h), left ventricular mass index (LVMI) (following Devereux's formula) and circulating levels of endothelin-1, aldosterone, renine, free adrenaline and noradrenaline. The ILVM in hypertensive patients was 139.6 +/- 35.9 g/m2 and in 124.0 +/- 31.8 g/m2 in normotensive (p < 0.05). The percentage of patients w...Continue Reading

Cardiovascular Diseases: Risk Factors

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.
