["Smoker's paradox" and reperfusion's strategy in acute myocardial infarction].

Unlabelled: Previous studies have shown that smokers with acute myocardial infarction (AMI) treated by thrombolysis have lower mortality rates than nonsmokers, a phenomenon often termed "smoker's paradox". This "smoker's paradox" has been rarely studied in case of primary angioplasty.

Aim Of The Study: To evaluate the impact of smoking status on the early mortality of patients admitted with AMI with regard to the strategy of reperfusion (intravenous thrombolysis versus primary angioplasty).

[Hemorrhagic risk of different perioperative anticoagulation protocols in patients implanted with a cardiac pacemaker or defibrillator: retrospective analysis in patients implanted in a community hospital].

Aims: Perioperative management of anticoagulation in patients referred for pacemaker or cardiac defibrillator implantation isn't consensual. Our objective was to evaluate, in a large cohort, hemorrhagic complications in patients having implantation or replacement of a cardiac pacemaker or defibrillator, and to assess perioperative anticoagulation effect on hemorrhagic risk.

Methods And Results: A cohort of 461 consecutive patients having implantation or replacement of a cardiac pacemaker or defibrillator has been analyzed.

[Pulmonary hypertension and heart failure: the role of pulmonary vasculature].

Left heart disease is the most common cause of pulmonary hypertension. Increased left-sided filling pressure leads to passive postcapillary venous hypertension. In some patients, pulmonary vasoconstriction and vascular remodeling may lead to a further increase in pulmonary pressure.

[Acute non protected main left coronary artery occlusion: a report of six cases treated by angioplasty].

Aim: Acute main left coronary artery occlusion is rarely observed during primary angioplasty in myocardial infarction. This retrospective study reports the results of six patients treated by angioplasty in a hospital without cardiac surgery department.

Patients And Methods: From 2002 to 2009, 746 patients were treated by primary angioplasty for acute coronary syndromes with ST elevation.
