BACKGROUND Stenting reduces both acute complications of coronary angioplasty and restenosis rates but increases subacute thrombosis rates and hemorrhagic complications when used with coumadin anticoagulation. METHODS AND RESULTS To simplify postcoronary stenting treatment and to reduce these drawbacks, we evaluated the 1-month outcome of a prospective(More)
BACKGROUND Nitric oxide (NO) donors, in addition to their vasodilator effect, decrease platelet aggregation and inhibit vascular smooth muscle cell proliferation. These actions could have beneficial effects on restenosis after coronary balloon angioplasty. METHODS AND RESULTS In a prospective multicenter, randomized trial, 700 stable coronary patients(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 To determine if female gender is an independent predictor of in-hospital mortality after percutaneous coronary intervention (PCI) for ST segment elevation myocardial infarction (STEMI). A higher early mortality rate after STEMI has been reported in women before the widespread use of PCI in STEMI. PCI improves the prognosis of STEMI, however, the effect(More)
The results of this study, conducted in 25 patients without myocardial infarction, showed that all the biologic markers of myocardial infarction, except the highly cardiospecific cardiac troponin I, increased in some patients after electrical cardioversion. These results allow us to conclude that electrical cardioversion, even preceded by a mechanical(More)
X-ray exposure of patient during coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) may have some deleterious effects. The dose area product (DAP), related to the effective dose, is a measure of stochastic risk and a potential quality indicator. The aim of our study was to assess radiation exposure of patients in a large(More)
BACKGROUND Exposure of patients to radiation from invasive cardiac procedures is high and may be deleterious. AIMS To assess the effectiveness of a dose-reduction programme based on radiation-protection training, according to the recommendations of the Euratom Council, the International Commission on Radiological Protection and the French Society of(More)

OBJECTIVES To evaluate practices for the protection from radiation of patients during coronary angiography (CA) and percutaneous coronary intervention (PCI), and to update reference values for the main radiation dose parameters. BACKGROUND Few multicenter data from large populations exist on radiation doses to patients during CA and PCI. METHODS RAY'ACT(More)
BACKGROUND Environmental parameters have been reported to be triggers of acute myocardial infarction (MI). However, the individual role of each parameter is unknown. We quantified the respective association of climate parameters, influenza epidemics and air pollutants with the onset of ST elevation MI (STEMI) in Paris and the surrounding small ring. (More)
