to define a correlation between echocardiographic parameters of right ventricular (RV) function and exercise capacity in a group of patients with stable chronic heart failure (CHF).30 patients with CHF (age=58.3±13 years, 29 men), defined as a left ventricular ejection fraction (LVEF) ≤0.45, had an echocardiographic examination followed by a 6-min walk test. RV function was evaluated by two parameters:...
The relationship between right ventricular function and severe tricuspid regurgitation is intricate: severe TR can lead to right ventricle dysfunction and changes in right ventricle morphology can aggravate a tricuspid regurgitation.Establish a correlation between regional and global right ventricular (RV) function parameters and TR severity.Forty consecutive patients with TR and left ventricle valve...
To determine the impact of obstructive sleep apnea (OSA) on left ventricle (LV) structure and function and to search for a relationship between systolic LV function and severity of OSA.40 subjects without any cardiac or pulmonary disease, referred for evaluation of OSA had overnight polysomnography and complete echocardiographic assessment with estimation of left ventricular myocardial performance...
The prevalence of chronic heart failure (CHF) is increasing in the world. Coronary artery disease is its most common cause in Europe. In Tunisia, valvular abnormalities were the leading aetiology of CHF in the eighties. We sought to determine its epidemiologic profile nowadays.99 patients were hospitalized between 2004 and 2008 for chronic heart failure in our center. We analysed their demographic...
