BACKGROUND AND AIMS OF THE STUDY The study aim was to assess the value of exercise stress testing in identifying asymptomatic patients with moderate or severe valvular aortic stenosis (AS). These patients generally develop symptoms during follow up, and require valvular replacement surgery (VRS) at one to three years after single symptom-limited exercise(More)
BACKGROUND The risk factors involved in the onset of atrial fibrillation (AF) are well known, but the predictive clinical and paraclinical parameters for the onset of AF in hypertensive patients have not been investigated specifically. METHODS AND RESULTS We retrospectively analyzed 97 consecutive patients with hypertension and no known history of AF or(More)
BACKGROUND For many years, cardiac auscultation has been the only available method for distinguishing between functional and organic murmurs; however, a more reliable differential diagnosis can now be achieved with Doppler echocardiography. The question remains as to whether a Doppler echocardiogram needs to be routinely recorded in the presence of a heart(More)
AIMS The purpose of this prospective study was to characterize the clinical profile of patients with atrial fibrillation (AF) in the urban population of a sub-Saharan African country and to assess how successfully current guidelines are applied in that context. METHODS AND RESULTS This prospective study involved 10 cardiologists in Cameroon. Enrolment(More)
Coronary arteriography was performed in 46 patients with type-II and type-IV hyperlipoproteinaemia. Type-II patients had a high prevalence of main left coronary disease and of distal coronary atherosclerosis, while type-IV patients usually had disease localised to the proximal coronary tree. These differences may be related to the differing(More)
In recent years coronary artery bypass grafting (CABG) has been extended to include patients with very low left ventricular ejection fractions (LVEF), also frequently with co-existing mild to moderate mitral valve regurgitation (MR). The question is, should such a MR be corrected simultaneously with a myocardial revascularization or not? Between January(More)
AIMS The purpose of this prospective study was to characterize the clinical profile of patients with atrial fibrillation (AF) in cardiology practice and to assess how successfully guidelines have been implemented in real-world practice. METHODS AND RESULTS This prospective study involved 23 cardiologists established in office practice in Geneva.(More)
