OBJECTIVE To determine whether oscillations in the cerebrovascular circulation undergo autonomic modulation in the same way as cardiovascular oscillations. DESIGN Cardiovascular and cerebrovascular oscillations were monitored at rest and during sympathetic stimulation (head up tilt). The association with and transmission of the oscillations in the(More)
Although thrombolytic therapy reduces mortality in patients with acute myocardial infarction (AMI), it is associated with a greater incidence of successive coronary events, and there is still no ideal diagnostic and therapeutic strategy for such patients. The present study verifies the value of negative predischarge exercise testing in identifying low-risk(More)
To assess the ability of transthoracic high-frequency two-dimensional echocardiography to detect atherosclerotic lesions in the descending portion of the left coronary artery, 30 consecutive patients with suspected coronary artery disease underwent two-dimensional echocardiographic examination 24 to 96 hours before coronary angiography. The descending(More)
Twenty-one patients surviving orthotopic cardiac transplantation were studied by serial M-Mode and cross-sectional echocardiography on the same day as endomyocardial biopsy (EBS) (n = 205) during a mean follow-up period of 7.7 +/- 6 months. Results of EBS and the corresponding echocardiograms were divided into three groups: (1) no rejection (62 patients);(More)
Little is known of mechanism of dialysis headache (DH). As suggested for migraine, a role for neuropeptides has been investigated. Twenty-four patients under haemodialysis were studied. Twelve of them suffered from DH. The remaining patients were headache free. Blood samples for radioimmunoassay of calcitonin gene-related peptide (CGRP) and substance P (SP)(More)
A twenty-four-hour blood pressure (BP) monitoring was performed in 20 normotensive and 20 hypertensive subjects, matched by sex and age. Blood pressure and heart rate (HR) variability were evaluated both as absolute and percent standard deviation. In agreement with the literature no significant difference in HR and BP variability was observed between the(More)
BACKGROUND/AIMS Patients with cirrhosis and ascites usually show alterations of systemic hemodynamics and are thus prone to develop arterial hypotension, which might result in cerebral hypoperfusion if cerebral autoregulation is impaired. METHODS We evaluated cerebral autoregulation in 15 patients with cirrhosis and ascites and 15 healthy subjects by(More)
Total knee arthroplasty (TKA) is a common surgical intervention for older individuals with advanced knee osteoarthritis (OA). TKA has been repeatedly shown to reduce the chronic knee pain associated with OA and improve physical functioning. [1-4]. Regardless, studies have also shown that individuals with OA who undergo TKA continue to have reduced(More)
UNLABELLED The diagnostic procedures for the assessment of transient ischemic attacks (TIA) include both brain imaging (computed tomography, nuclear magnetic resonance) and cerebrovascular investigation by means of ultrasound studies and angiography. Transcranial Doppler sonography (TCD) has not yet become a widely used diagnostic tool, although it allows(More)
