BACKGROUND In animal models, brief periods of ischemia performed just at the time of reperfusion can reduce infarct size, a phenomenon called postconditioning. In this prospective, randomized, controlled, multicenter study, we investigated whether postconditioning may protect the human heart during coronary angioplasty for acute myocardial infarction.

Hyperhomocysteinemia has been shown to constitute an independent risk factor for premature occlusive arterial disease (N Engl J Med 324:1149), a frequent complication in chronic uremic patients in whom homocysteine (Hcy) accumulation has been reported to occur. We prospectively determined fasting plasma level of total, protein-bound Hcy in 118 adult chronic(More)
BACKGROUND We previously demonstrated that ischemic postconditioning decreases creatine kinase release, a surrogate marker for infarct size, in patients with acute myocardial infarction. Our objective was to determine whether ischemic postconditioning could afford (1) a persistent infarct size limitation and (2) an improved recovery of myocardial(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)
BACKGROUND Moderate hyperhomocysteinaemia, as occurs in chronic renal failure patients, is an established independent risk factor for atherosclerotic arterial occlusive accidents, the incidence of which is abnormally high in such patients. Folic acid supplementation has been shown to reduce plasma homocysteine level in end-stage renal disease patients(More)
Moderate hyperhomocysteinemia, a risk factor for premature atherosclerosis, is present in chronic uremic patients. We prospectively evaluated the effects of sequential supplementation with pyridoxine (70 mg/day) and folic acid (10 mg/day) for two 3-month periods in 37 nondialyzed patients (29 males) with creatinine clearance (CCr) ranging from 10 to 80(More)
BACKGROUND Cystinosis is a rare autosomal recessive disorder characterized by an accumulation of intralysosomal cystine due to a defect in cystine transport across the lysosomal membrane. This disorder can be treated specifically using high doses of cysteamine. Accurate measurement of intracellular cystine content is necessary for the diagnosis and(More)
Studies on attentional processes in obsessive-compulsive disorder (OCD) have been inconsistent. The present study focused on the question of sustained attention in OCD, using the 'Degraded Stimulus Continuous Performance Test' (DS-CPT) sensitivity index over time. This study included 20 OCD patients and 25 control subjects, comparable in sex, age and(More)
AIMS Dilated cardiomyopathy (DCM) is a major cause of heart failure with a high familial recurrence risk. So far, the genetics of DCM remains largely unresolved. We conducted the first genome-wide association study (GWAS) to identify loci contributing to sporadic DCM. METHODS AND RESULTS One thousand one hundred and seventy-nine DCM patients and 1108(More)
Carnitine palmitoyl transferase II deficiency, an inherited disorder of long-chain fatty acid oxidation, may result in either a mild form (muscle disease in adults) or a severe form (hepatocardiomuscular syndrome in infants). The difference in severity between these two forms is related to a difference in levels of residual carnitine palmitoyl transferase(More)
