OBJECTIVES The aim of the study was to compare head-to-head the performance of exercise tolerance test-stress echocardiography (ex-Echo) and exercise stress-perfusion nuclear imaging (exercise-single-photon emission computed tomography [ex-SPECT]) for the diagnosis of coronary artery disease (CAD) in patients evaluated at the chest pain unit with delay from(More)
AIM To investigate the effects of long-term albumin administration on survival, recurrence of ascites and onset of other complications. METHODS One hundred consecutive patients admitted for first-onset ascites were randomized to receive diuretics plus human albumin 25 g/wk in the first year and 25 g every two wk thereafter (group 1) or diuretics alone(More)
Numerous studies have pointed out the frequent association of tetralogy of Fallot (TF) with other cardiovascular defects and coronary tree anomalies. We found cardiac defects in 181 (68%) out of 265 patients with TF investigated by catheterization and selective coronary angiography. These anomalies were isolated in 88 cases (49%) and associated with others(More)
OBJECTIVE To evaluate whether the circadian rhythm of body core temperature (CRT degrees ) can differentiate Multiple-System Atrophy (MSA) from Idiopathic Parkinson's disease (IPD). METHODS We evaluated 14 patients with probable MSA, seven with IPD, and eight controls. After a preliminary evaluation of cardiovascular autonomic function, rectal temperature(More)
Since alterations in the autonomic nervous system are thought to play a major role in the pathogenesis of vasovagal syncope, we characterized the chronic autonomic profile of 44 patients with syncope and 20 healthy subjects by means of heart rate variability using 24-hour Holter recordings (time- and frequency-domain indexes), and evaluated whether the(More)
To assess whether an increased production of nitric oxide is involved in the circulatory and renal alterations of cirrhosis, we evaluated systemic hemodynamics (echocardiography), renal hemodynamics, and sodium handling (lithium clearance method), plasma renin activity (PRA), aldosterone (PAC), and norepinephrine in 7 patients (3 men, mean age 65 +/- 2(More)
In experimental animals, C-type natriuretic peptide (CNP) has vasodilating, hypotensive, and natriuretic activities. The role of circulating CNP in the overall regulation of cardiac and renal function in humans is less defined, in both health and disease. We measured cardiac volumes, diastolic and systolic functions, systemic (Doppler echocardiography) and(More)
The objective of this study was to determine the cardiovascular effects of chronic stimulation of the posterior hypothalamic area (PHA) in cluster headache (CH) patients. Systolic and diastolic blood pressure (SBP, DBP), cardiac output, total peripheral resistance (TPR), heart rate (HR) and breathing were monitored at supine rest and during head-up tilt(More)
OBJECTIVE To test the autonomic control of cardiovascular reflexes and heart rate variability (HRV) at rest and during orthostatic stress in narcolepsy with cataplexy (NC). METHODS Ten NC patients with a hypocretin deficit and 18 control subjects underwent head-up tilt test (HUTT), Valsalva manoeuvre, deep breathing and cold face under controlled(More)
OBJECTIVE To evaluate the cardiovascular response to active postural changes in pregnancy. DESIGN Prospective study. SETTING Outpatient Clinic, Fetal Maternity Unit. PARTICIPANTS Sixteen healthy women referred prior to pregnancy. METHODS Heart rate, arterial pressure, echocardiographic end-diastolic and end-systolic left ventricular volumes(More)
