Background. Hemoglobin SC disease is one of the most frequent hemoglobinopathy. Surprisingly, few studies were dedicated to this disease, currently considered as a mild variant of homozygous sickle cell disease. The aim of this study was to update our knowledge about hemoglobin SC disease. Design and Methods. We conducted this study in a monocentric series(More)

OBJECTIVE The aim of this study was to assess the angiographic results of the radial artery as a coronary bypass conduit at long term (>5 years). METHODS Radial artery grafts were controlled in 202 patients at 10.1 years by conventional angiography (n = 79) and computed tomography (n = 123). Clinical or paraclinical evidence of ischemia was noted in 81(More)
Cardiovascular (CV) diseases in type 2 diabetes (T2DM) represent an enormous burden with high mortality and morbidity. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have recently emerged as a new antidiabetic class that improves glucose control, as well as body weight and blood pressure with no increased risk of hypoglycemia. The first CV outcome study(More)
AIM This open-label, randomized, and multicentre trial tested the hypothesis that, on a background of aspirin, continuing clopidogrel would be superior to stopping clopidogrel at 12 months following drug-eluting stent (DES) implantation. METHODS AND RESULTS Patients (N = 1799) who had undergone placement of ≥1 DES for stable coronary artery disease or(More)
In pulmonary hypertension (PH), right ventricular (RV) dysfunction and failure is the main determinant of a poor prognosis. We aimed to characterize RV structural and functional differences during adaptive RV remodeling and progression to RV failure in a large animal model of chronic PH. Postcapillary PH was created surgically in swine (n = 21). After an 8-(More)
BACKGROUND Pulmonary hypertension (PH) is characterized by pulmonary arterial remodeling that results in increased pulmonary vascular resistance, right ventricular (RV) failure, and premature death. Down-regulation of sarcoplasmic reticulum Ca(2+)-ATPase 2a (SERCA2a) in the pulmonary vasculature leads to perturbations in calcium ion (Ca(2+)) homeostasis and(More)
Increased left ventricular end-diastolic pressure (LVEDP) with exercise is an early sign of heart failure with preserved left ventricular ejection fraction (LVEF). The abnormal exercise increase in LVEDP is nonlinear, with most change occurring at low-level exercise. Data on non-invasive approach of this condition are scarce. Our objective was assessing(More)
Nowadays cannabis is the most common substance of drug abuse and pathophysiological effects have been described on the cardiovascular system. Yet there is limited information concerning cannabis induced acute coronary syndrome and the exact contribution of cannabis smoking to coronary artery disease and its mechanism are not known. We describe a case of(More)
