Although radial approach has been shown to be feasible for coronary angiography, angioplasty, and even stent placement, there have been no prospective evaluations of ease and safety of left radial approach for coronary angiogram. We examined procedural duration and success as well as complications in 415 consecutive patients. Radial artery occlusion was(More)
OBJECTIVES To determine if B-type natriuretic peptide (BNP) measurement could be useful in determination of functional capacity in patients suffering from chronic heart failure. BACKGROUND Evaluating functional capacity is a crucial factor in the follow-up of patients with chronic heart failure. There are numerous methods for measuring functional capacity(More)
It is well known that atrial fibrillation can lead to heart failure, and is attributed to rapid ventricular rate (tachycardia-induced cardiomyopathy). Some recent studies suggest the possible existence of an intrinsic left-ventricular factor related to atrial fibrillation, irrespective of other elements. In order to demonstrate the implication of this(More)
Inhibitors of serotonin uptake are drugs prescribed without recognised cardiovascular risk. The authors report a case of torsades de pointes following Citalopram ingestion. In this patient, the proof of reintroduction in a hospital environment resulted in prolongation of the QT interval. Screening of patients for acquired or congenital long QT intervals is(More)
Brain natiuretic peptide (BNP) is a hormone secreted specifically by the left ventricular myocytes. Its concentration is correlated with the severity of symptomatic or asymptomatic left ventricular dysfunction. The measurement of BNP has several applications from the screening of populations to the monitoring of the effects of treatment and the evaluation(More)
To examine the ability of myocardial contractile reserve (MCR) assessment to predict the improvement of left ventricular ejection fraction with treatment by carvedilol, a prospective study was undertaken in 85 patients with chronic heart failure and left ventricular ejection fraction < 45%. Low dose dobutamine echocardiography (DSE), a 6-min walk test and(More)
Distal transcutaneous oxygen pressure measurement (TcPo2) is a noninvasive method of evaluating tissular hypoxemia in peripheral arterial disease. The poststress area of hypoxemia is a usefull technique for globally quantifying different parameters represented by TcPo2 curves during exercise. Although its use is increasingly widespread, the reproducibility(More)
Treatment with non-steroid anti-inflammatory drugs associated with a prostaglandin analogue is common, but the potential cardiovascular effects are largely unknown. The authors report a case of myocardial necrosis and anaphylactic shock due to treatment with diclofenac and misoprostol. The reintroduction of the treatment in hospital led to the recurrence of(More)
The aim of this study was to assess prospectively the feasibility, safety and quality of coronary angiography performed by a left radial arterial approach. The investigation was performed under local anesthesia with a Lidocaine gel using Judkins 5f catheter. A bolus of heparin was injected intravenously at the start of the procedure (no heparin in phase 0.2(More)
