1. Blood pressure, glomerular filtration rate (GFR) and renal plasma flow (RPF) were measured in twenty-three patients with essential hypertension and in twenty-one control subjects. Plasma renin concentration was measured in all the hypertensive patients and in fifteen control subjects. 2. GFR and RPF were similar in the hypertensive group and in the control group, whereas the renal vascular r...

Recently, coronary microvascular function was documented to be impaired even in patients with prehypertension. However, the impact of antihypertensive level on improvement of coronary microvascular dysfunction in hypertensive patients remains to be established. We investigated the optimal blood pressure achieved with treatment of antihypertensive agents for improvement of coronary microvascular...

BACKGROUND Hypertension (HBP) is modifiable risk factor, whose control may reduce cardiovascular disease in patients with human immunodeficiency virus (HIV). OBJECTIVE To estimate the prevalence of hypertension and describe the characteristics of patients with hypertension infected by HIV/AIDS. METHODS A cross-sectional study aligned to a cohort of patients with HIV/AIDS. The study consider...

Left ventricular (LV) hypertrophy is an important predictor of morbidity and mortality in hypertensive patients, and its geometric pattern is a useful determinant of severity and prognosis of heart disease. Studies on LV geometric pattern involving large number of Nigerian hypertensive patients are limited. We examined the LV geometric pattern in hypertensive patients seen in our echocardiograp...

BACKGROUND Silent ischaemia has been reported to be associated with an increased risk of myocardial infarction and sudden death in a wide range of patient groups. The aim of this study was to examine the prevalence of silent ischaemia in hypertensive patients with and without left ventricular hypertrophy (LVH). METHODS Twenty hypertensive patients participating in the Anglo-Scandinavian Cardi...

In addition to disorders in lipoprotein metabolism, several other factors are involved in the development of atherosclerotic changes in end-stage renal disease (ESRD) patients. One of these is arterial hypertension. We evaluated serum lipids-total cholesterol (TC), triglycerides (TG), apolipoproteins (AI , A II , B, E), lipoprotein(a) [Lp(a)]-in 109 ESRD patients on dialysis [46 on hemodialysis...

Malignant hypertension is a unique and natural model for the study of abnormalities of left ventricular function due to arterial hypertension, because the development and regression of these abnormalities can be observed in a short period. Studies of ventricular function by radionuclide ventriculography, either before or after therapy, have not been previously reported in malignant hypertensive...

The effect of continuously slowing respiration (from 0.46 to 0.05 Hz, eg, from 30 to 3 breaths per minute) on cardiovascular variables was studied in 14 hypertensive patients and 16 normotensive subjects. Beat-to-beat time-frequency (Wigner) distributions were used for dynamic analysis of RR interval and systolic and diastolic pressures. Dominant breathing frequency at rest did not differ in hy...

Objective: There is not enough information in the literature conducted about importance of serum uric acid levels hypertensive emergency patients. Our study aims to investigate role patients admitted department due high blood pressure. Materials and methods: Hypertensive with acute target organ damage pressure 180/110 mmHg above (group I), urgency without II), uncontrolled hypertension systolic...
