Correlation between intracoronary physiology and myocardial perfusion imaging in patients with severe aortic stenosis.

Background: Aortic stenosis (AS) is frequently associated with coronary artery disease (CAD). However, the best tool to functionally assess CAD in AS remains undetermined. Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) have never been validated in AS.

Treatment of chronic pulmonary aspergillosis with voriconazole: review of a case series.

Purpose: Chronic pulmonary aspergillosis (CPA) is a rare disease that primarily affects subjects with moderate immunodepression and/or structural alterations in the lung.

Methods: Data for patients with probable CPA were collected over 24 months. Patients with probable CPA received oral voriconazole, and clinical, laboratory and radiological follow-up was performed at 3, 6 and 12 months.

Comparison between low-dose dobutamine echocardiography and thallium-201 scintigraphy in the detection of myocardial viability in patients with recent myocardial infarction.

Aim: To compare the predictive value of thallium-201 single photon emission computed tomography (SPECT) scintigraphy (Sci) and low-dose dobutamine echocardiography (Dob) in predicting late recovery of dysfunctioning myocardium in patients with recent, uncomplicated myocardial infarction (MI).

Methods And Results: 19 patients (18 male, aged 58+/-8 years) with recent MI and ejection fraction <50% (35.5+/-8.

Effects of ACE inhibition in normotensive patients with chronic glomerular disease and normal renal function.

A double-blind, placebo-controlled study was carried out to assess the effects of a three-month treatment with a new ACE inhibitor, Benazepril (BNZ), on systemic and renal hemodynamics, and urine protein excretion, in 20 patients with chronic glomerulonephritis, normal blood pressure (130/83 +/- 16/10 mm Hg), and normal renal function (creatine clearance 106 +/- 25 ml/min). Treatments with placebo or BNZ were assigned randomly. A wide range of proteinuria lowering effect was observed in overall population (from 1 to 84%, average 34%).

Renal functional reserve in patients with essential hypertension: effect of inhibition of the renin--angiotensin system.

1. Urinary albumin excretion and the effect of an acute oral protein load (a meat meal) on glomerular filtration rate ('renal functional reserve') were evaluated in 15 essential hypertensive patients with preserved renal function and compared with 12 normal subjects. 2.
