A new method and apparatus for non-disruptive blood pressure (BP) recording in the finger based on the vascular unloading technique is introduced. The instrument, in contrast to intermittent set point readjustments of the conventional vascular unloading technique, delivers BP without interruptions, thus refining the Penáz' principle. The method is based on(More)

If high sodium intake is involved in the pathogenesis of essential hypertension, the effects of changing the sodium intake should be demonstrable in the susceptible part of the normotensive population. Therefore, we have investigated the effects of moderate salt restriction in 52 young normotensive subjects with and without a family history of hypertension;(More)
AIMS This study aimed to determine the prevalence of renal artery stenosis (RAS) and associated risk factors in patients undergoing cardiac catheterization for suspected coronary artery disease (CAD). METHODS One hundred and seventy-seven consecutive patients (62 females) with a serum creatinine concentration <2.0mg.dl(-1) were studied. Abdominal(More)
Orthostatic hypotension in patients with cobalamin (Cbl) deficiency has been reported previously in isolated cases but we are not aware of detailed systematic studies of hemodynamic and autonomic nervous system function in patients with cobalamin deficiency. We investigated hemodynamic and autonomic responses to 60 degrees passive head up tilt (HUT) in 21(More)
20 normotensive subjects (10 with a family history of hypertension) were investigated as to whether moderate salt restriction and/or a high potassium intake had a beneficial effect on blood pressure regulation and prevention of hypertension. In all subjects a moderate reduction of salt intake from 200 to 50 mmol/day over 2 weeks reduced the rise in blood(More)
BACKGROUND Intra-dialytic morbid events (IDME) such as intra-dialytic hypotension (IDH) and muscle cramps frequently complicate haemodialysis (HD). Cardiac dysfunction is highly prevalent in HD patients. We investigated the relationship between proto-dialytic (i.e. early intra-dialytic) cardiac function and IDME in HD patients. METHODS Heart rate,(More)
BACKGROUND Little is known about the epidemiology of chronic kidney disease (CKD) in patients with suspected sleep apnoea (SA). METHODS Glomerular filtration rate (eGFR) was calculated in consecutive patients referred for full-night observed in-hospital polysomnography. SA was defined as the respiratory disturbance index (RDI) > 5. RESULTS One hundred(More)
Parallel fluctuations of potential difference (P.D.) across oral and rectal mucosa are probably related to the activity of autonomic nerves rather than adrenal steroids. Unlike rectal mucosa, oral mucosa does not respond to exogenous or endogenous aldosterone. Therefore subtraction of oral P.D. from rectal P.D. gives a closer indication of mineralocorticoid(More)
Medical scientists try to improve the accuracy of human body composition measurement by segmental Bioelectrical Impedance Analysis (BIA). Determination of body composition includes estimation of total body water, fat-free mass and extra-and intra-cellular water, which are of great importance in disease states like cancer, malnutrition, disturbances of(More)
