Exercise training improves diastolic function in heart failure patients.

Purpose: The study's purpose was to analyze the effects of exercise training on exercise tolerance and left ventricular systolic function and structure in heart failure patients with preserved, mild, and moderate to severe reduction of left ventricular ejection fraction (LVEF).

Methods: Ninety-eight patients with moderate to severe (n = 34), mild (n = 33), and preserved (n = 31) LVEF were randomly assigned to exercise training plus usual care (n = 65) or usual care alone (n = 33) in a randomization ratio of 2:1. Left ventricular function, left ventricular dimensions, and exercise tolerance were assessed before and after each intervention.

Serum oxidizability potential of ischemic heart disease patients is associated with exercise test results and disease severity.

Aim: To find out whether serum oxidizability potential correlates with exercise test (EXT) parameters and predicts their results in chronic ischemic heart disease (IHD) patients.

Methods: Oxidizability potential was determined in a group of chronic IHD patients who underwent a symptom limited EXT upon initiation of a cardiac rehabilitation program. The thermo-chemiluminescence (TCL) assay was used to assess serum oxidizability potential.

Prevalence of rhinosinusitis among atypical cystic fibrosis patients.

The objective of this paper is to study the correlation between sinonasal involvement and type of cystic fibrosis (CF) in Israeli's CF patients. The comparative study includes 70 CF patients: 40 typical and 30 atypical CF patients. History and physical examination data were recorded, including endoscopic nasal examination as well as sinus computer tomography scan.

Mild cystic fibrosis and normal or borderline sweat test in patients with the 3849 + 10 kb C-->T mutation.

Different mutations in the cystic fibrosis (CF) gene appear to contribute to heterogeneity of the CF phenotype. We investigated 15 patients with CF who have the 3849 + 10 kb C-->T mutation. All were Ashkenazi Jews.
