RATIONALE Telomere length is considered a marker for biological aging. Chronic obstructive pulmonary disease (COPD) may be associated with premature aging. OBJECTIVES To test the hypothesis that patients with COPD experience accelerated telomere shortening and that inflammation is linked to this process. METHODS We measured telomere length, using a(More)
BACKGROUND Experimental and clinical evidence suggests that cyclosporine may attenuate reperfusion injury and reduce myocardial infarct size. We aimed to test whether cyclosporine would improve clinical outcomes and prevent adverse left ventricular remodeling. METHODS In a multicenter, double-blind, randomized trial, we assigned 970 patients with an acute(More)
Chronic obstructive pulmonary disease (COPD) is a major risk factor for cardiovascular disease. Polycythemia, a common complication of hypoxic COPD, may affect systemic vascular function by altering blood viscosity, vessel wall shear stress (WSS), and endothelium-derived nitric oxide (NO) release. Here, we evaluated the effects of hypoxia-related(More)
Mesenchymal stem cells (MSC) are known to repair broken heart tissues primarily through a paracrine fashion while emerging evidence indicate that MSC can communicate with cardiomyocytes (CM) through tunneling nanotubes (TNT). Nevertheless, no link has been so far established between these two processes. Here, we addressed whether cell-to-cell communication(More)
AIM The MITOCARE study evaluated the efficacy and safety of TRO40303 for the reduction of reperfusion injury in patients undergoing revascularization for ST-elevation myocardial infarction (STEMI). METHODS Patients presenting with STEMI within 6 h of the onset of pain randomly received TRO40303 (n = 83) or placebo (n = 80) via i.v. bolus injection prior(More)
RATIONALE Chronic obstructive pulmonary disease (COPD) is associated with lung fibroblast senescence, a process characterized by the irreversible loss of replicative capacity associated with the secretion of inflammatory mediators. However, the mechanisms of this phenomenon remain poorly defined. OBJECTIVES The aim of this study was to analyze the role of(More)
BACKGROUND Right ventricular (RV) function is a strong predictor of patient outcome after cardiac surgery. Limited studies have compared the predictive value of RV global longitudinal strain (RV-GLS) with tricuspid annular plane systolic excursion (TAPSE) and RV fractional area change (RVFAC) in this setting. METHODS The study included 250 patients (66 ±(More)
The "obesity paradox" that patients with high body mass index (BMI) have good prognoses remains controversial. This study aimed to assess the impact of BMI on clinical outcomes in patients who underwent transcatheter aortic valve implantation (TAVI). Data from the French national TAVI registry were collected for 3,072 patients who underwent TAVI from(More)
AIMS To determine whether severity patterns or nocturnal ventilation to treat sleep-disordered breathing (SDB) during chronic heart failure (CHF) is associated with adverse outcomes. Although SDB is frequent during CHF, the relationships between SDB and CHF outcomes are unknown. METHODS AND RESULTS A total of 384 CHF patients (82% men, mean age 59 ± 13(More)
CONTEXT International guidelines recommend an early invasive strategy for patients with high-risk acute coronary syndromes without ST-segment elevation, but the optimal timing of intervention is uncertain. OBJECTIVE To determine whether immediate intervention on admission can result in a reduction of myocardial infarction compared with a delayed(More)
