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)
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)
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)
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)
The authors report sequential association during the same general anaesthetic of coronary bypass surgery on the beating heart and surgery of an abdominal aortic aneurysm. Two aorto-coronary bypass grafts were carried out without cardiopulmonary bypass using the two pediculated internal mammary arteries (without manipulation of the ascending aorta),(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)
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)
One reason why quantifying plaque regression is difficult is the poor spatial control of the shooting angle whether in angiography or ultrasonography techniques. A computer-assisted technique has been developed to assess absolute carotid plaque dimensions from B-mode ultrasonography, with enhanced capability of comparative examinations at large time(More)
