Left ventricular diastolic and systolic function in normotensive obese subjects: influence of degree and duration of obesity.
The present study was carried out to evaluate systolic and diastolic parameters in overweight and moderately obese, but otherwise healthy subjects, and in a lean control group, to determine whether degree and duration of obesity can influence left ventricular function. A total of 27 subjects, 17 overweight or with moderate obesity and 10 lean, healthy subjects were included. Patients were divided into three groups according to their body mass index (BMI) and to Garrow's criteria as follows: lean control group (BMI less than 25 kg.m-2); overweight subjects (BMI from 25 to 30 kg.m-2); moderately obese subjects (BMI greater than 30 less than 40 kg.m-2). Systolic and diastolic parameters were m…
Therapeutic management of elderly hypertensives with concomitant ischaemic heart disease.
CHARACTERISTICS OF ELDERLY HYPERTENSIVES: Hypertension is most prevalent in older patients and is associated with increasing morbidity and mortality with age. Elderly hypertensives often suffer from concomitant diseases, such as ischaemic heart disease, caused by age-induced modifications to the cardiovascular system, haemodynamic function and neurohormone activity. THERAPEUTIC MANAGEMENT: Therapeutic management of elderly hypertensives with concomitant ischaemic heart disease must take account of the pharmacodynamic and pharmacokinetic changes that occur in older subjects and drugs should be selected for their efficacy in both diseases. Since elderly subjects often metabolize drugs more sl…
Effect of obesity on left ventricular function studied by radionuclide angiocardiography
Several studies have shown a significant association of obesity with cardiovascular morbidity and mortality. The present study was carried out to investigate central and systemic haemodynamics in overweight and moderate obese, but otherwise healthy subjects, and in a lean control group to determine whether obesity can influence left ventricular performance per se. In this study an attempt has been made to eliminate misleading factors, such as diabetes, lipid abnormalities and hypertension. A total of 67 subjects, 44 with overweight or moderate obesity and 23 lean healthy subjects, were included. Patients were divided into three groups according to BMI levels and Garrow's criteria as follows…
Hemodynamic Changes in Patients with Essential Hypertension after Therapy with Muzolimine
Muzolimine is a new nonsulfonamide diuretic belonging to the pyrazolinone group (1).It is a potent high-ceiling diuretic agent like furosemide and bumetanide with long duration of action like thiazides (1, 2).
Clinical and haemodynamic effects of ketanserin in lean and obese hypertensive patients.
Systemic and central haemodynamics were evaluated in 10 lean and 10 obese hypertensive patients (World Health Organization stage I – II) after treatment for 8 weeks with a serotoninergic antagonist, such as ketanserin. Blood pressure and heart rate were recorded and first-pass radionuclide angiocardiography was performed to determine cardiac output, cardiac index and ejection fraction of the left ventricle; total peripheral resistance was also calculated. In both obese and lean patients, ketanserin significantly reduced diastolic ( P < 0.05) and mean ( P < 0.005) blood pressure but no significant changes in systolic blood pressure, cardiac output, cardiac index and ejection fraction …
