What Leads to a Patient Refusal for Ambulatory Surgery? A Logistic Regression Prediction Model Based on a 5-year Retrospective Analysis of Patients with Abdominal Wall Hernia.

Introduction: Ambulatory surgery has proven benefits in patient wellbeing and cost reduction in healthcare systems. However, some patients referred for ambulatory surgery are refused and directed instead towards inpatient care, which generates several drawbacks. The reasons for this refusal have not been yet studied.

Rosuvastatin slows the development of diastolic dysfunction in calcific aortic stenosis.

Background And Aim Of The Study: The study aims were to test the effect of rosuvastatin on the progression of left ventricular (LV) diastolic function in patients with aortic stenosis (AS), and to evaluate the use of beta-natriuretic-peptide (BNP) as a marker of diastolic dysfunction in this condition.

Methods: Sixty-one hypercholesterolemic, consecutive new referrals with moderate AS were administered rosuvastatin (Crestor) 20 mg/day for 18 months, while a further 60 subjects with normal cholesterol levels remained untreated. The LV diastolic function was determined using conventional Doppler echocardiography, tissue Doppler imaging (TDI); BNP plasma levels were monitored when subjects entered the study and then assessed prospectively at six-month intervals until the study end.

Analysis of variability and reproducibility of echocardiography measurements in valvular aortic valve stenosis.

Background: Doppler echocardiography is the most frequent method for detecting and evaluating the severity of valvular aortic stenosis. The aim of this study was to assess the variability and reproducibility of echocardiographic parameters including aortic valve area (AVA), peak aortic jet velocity (V(max)), velocity ratio (V(LVOT)/V(max)), peak gradient (G(max)) and mean gradient (G(mean)) in aortic stenosis (AS) patients.

Methods: Doppler echocardiograms were obtained from 150 randomly selected patients (56.

Rosuvastatin affecting aortic valve endothelium to slow the progression of aortic stenosis.

Objectives: The objective of this study was to test the effect of a 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitor on the progression of moderate to severe aortic stenosis as measured by echocardiography.

Background: Recent retrospective studies support the hypothesis that statins slow the progression of aortic stenosis.

Methods: We performed an open-label, prospective study evaluating 121 consecutive patients with asymptomatic moderate to severe aortic stenosis (aortic valve area > or = 1.
