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)
BACKGROUND Hemoglobin sickle cell disease is one of the most frequent hemoglobinopathies. Surprisingly, few studies have been dedicated to this disease, currently considered to be a mild variant of homozygous sickle cell disease. The aim of this study was to update our knowledge about hemoglobin sickle cell disease. DESIGN AND METHODS The study involved a(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)
BACKGROUND Few data are available on primary percutaneous coronary intervention (pPCI) in nonagenarians. In a large prospective registry on pPCI for STEMI we compared the demographics, procedural and in-hospital outcomes between nonagenarians (age ≥ 90 years) and patients aged < 90 years. METHODS AND RESULTS We included 26,157 consecutive patients with(More)
AIMS Latent heart failure at rest can be observed in a number of patients upon exercise. Considering left atrial (LA) remodelling as the reflection of the cumulative effects of the LV filling pressure (FP) over time, our aim was to investigate whether the LA volume would predict abnormal exercise LVFP. METHODS AND RESULTS Ninety patients (58.6 ± 10.8(More)
Chronic volume overload in sickle-cell anemia (SCA) is associated with left ventricular (LV) enlargement and hypertrophy. The effect of the disease on LV systolic function remains debated. The aim of our study was to investigate LV systolic function in SCA patients using 2D speckle-tracking imaging. We compared 30 steady state asymptomatic adult SCA(More)
BACKGROUND Management of increased referrals for transthoracic echocardiography (TTE) examinations is a challenge. Patients with normal TTE examinations take less time to explore than those with heart abnormalities. A reliable method for assessing pretest probability of a normal TTE may optimize management of requests. AIM To establish and validate, based(More)
