Most studies on the natural course of coronary artery spasm in patients with normal or nearly normal coronary arteries are based on medium-term follow-up in small populations. The present series includes 277 successive patients with a median follow-up of 89 months (range: 1 to 198 months). There were 206 men and 71 women whose mean age was 53.6 +/- 9.3(More)
BACKGROUND Pulmonary vein isolation (PVI) using cryoballoon (CB) catheter is a new technique for atrial fibrillation (AF) ablation. Previous studies used computer tomography (CT) or magnetic resonance imaging (MRI) scan to determine the pulmonary vein (PV) diameter and anatomy for choosing the CB size. We evaluated pre-ablation(More)

Several therapeutic substances can cause torsades de pointes, especially if they prolong the QT interval and/or if there is an associated hypokalaemia. Certain second generation H1 antihistamines have been incriminated in the occurrence of such ventricular arrhythmias, such as terfenadine and astezimole, which have been withdrawn. Cetirizine, widely used in(More)
OBJECTIVES Venous stasis in bedridden patients is recognized as one of the risk factors for venous thromboembolism but the phenomena is known to occur in ambulatory subjects and another cause must be involved. We investigated a series of consecutive ambulatory patients with venous thromboembolism in order to distinguish the particular clinical(More)
Prasugrel and ticagrelor are potent P2Y12-ADP receptor antagonists which are superior to clopidogrel in acute coronary syndromes. To date no clinical trial directly compared these two drugs. Platelet reactivity correlates with ischemic and bleeding events in patients undergoing percutaneous coronary intervention. Recent pharmacological studies have observed(More)
Left ventricular pseudo-false aneurysm is caused by a discrete rupture of the myocardial wall which remains circumscribed within the wall itself, realising a cavity joined to the left ventricle by a narrow neck. It is an extremely rare complication of myocardial infarction. Two cases diagnosed in vivo by left ventriculography are reported. Their diagnosis(More)
Ischaemia has been the suggested mechanism of simultaneous left bundle branch block and chest pain on effort with normal coronary angiography. This hypothesis is very controversial and was not the mechanism in the two new cases of this syndrome. The two patients in whom effort pain and left bundle branch block were observed had been treated for paroxysmal(More)
