B-CONVINCED: Beta-blocker CONtinuation Vs. INterruption in patients with Congestive heart failure hospitalizED for a decompensation episode.

AIMS: Whether or not beta-blocker therapy should be stopped during acutely decompensated heart failure (ADHF) is unsure. METHODS AND RESULTS: In a randomized, controlled, open labelled, non-inferiority trial, we compared beta-blockade continuation vs. discontinuation during ADHF in patients with LVEF below 40% previously receiving stable beta-blocker therapy. 169 patients were included, among which 147 were evaluable. Mean age was 72 +/- 12 years, 65% were males. After 3 days, 92.8% of patients pursuing beta-blockade improved for both dyspnoea and general well-being according to a physician blinded for therapy vs. 92.3% of patients stopping beta-blocker. This was the main endpoint and the upper limit for unilateral 95% CI (6.6%) is lower that of the predefined upper limit (12.5%), indicating non-inferiority. Similar findings were obtained at 8 days and when evaluation was made by the patient. Plasma BNP at Day 3, length of hospital stay, re-hospitalization rate, and death rate after 3 months were also similar. Beta-blocker therapy at 3 months was given to 90% of patients vs. 76% (P < 0.05). CONCLUSION: In conclusion, during ADHF, continuation of beta-blocker therapy is not associated with delayed or lesser improvement, but with a higher rate of chronic prescription of beta-blocker therapy after 3 months, the benefit of which is well established.

Surgical or medical treatment for thrombus straddling the patent foramen ovale: impending paradoxical embolism? Report of four clinical cases and literature review.

BACKGROUND: Thrombus straddling the patent foramen ovale (TSFO) is a rare event. It occurs in the presence of pulmonary embolism and can be responsible for paradoxical embolism. The aim of this report is to guide the optimal choice of treatment for TSFO in different clinical contexts. METHODS: A PubMed search was conducted of articles published between 1985, when the first TSFO was reported, and 2007. We identified 93 cases of TSFO diagnosed by echocardiography, nine of which were excluded because of lack of information. We analysed data from these 84 patients plus a further four seen at three French cardiology departments. RESULTS: The patients' mean age was 58 years. Pulmonary embolism was present in 94% of cases, and was severe in 34%. Paradoxical embolism, before or after treatment, was found in 44% of cases. Fifty-five patients were treated surgically, 21 were treated with heparin, and 11 received thrombolysis. The mortality rates for the treatments were 13, 14 and 36%, respectively. Patients who received heparin were older (60+/-17 years) and had more strokes (11/21) than the surgical group (56+/-15 years, 14/55). The group that received thrombolysis was more likely to have haemodynamic compromise. CONCLUSION: Medical treatment with heparin tends to be used as a second option in patients with more frequent comorbidities and strokes but the mortality rate is similar to that in the surgical group. Surgery seems to be justified in the prevention of paradoxical embolism. Thrombolysis is more frequently chosen in the higher risk group and is associated with the greatest mortality.

Heart valve regurgitation, pergolide use, and parkinson disease: an observational study and meta-analysis.

OBJECTIVE: To investigate the prevalence and risk factors of heart valve disease in patients having PD treated with pergolide. DESIGN: Prospective observational study. SETTING: Patients were recruited at the Hôpital de la Pitié-Salpêtrière, Paris, France. Patients Ninety-six patients having PD treated with pergolide for longer than 3 months vs 50 control subjects. Intervention Standardized echocardiography performed by an investigator blinded to treatment status. Main Outcome Measure Moderate to severe regurgitation in at least 1 heart valve. RESULTS: One hundred thirty-three echocardiograms (86 in the pergolide-treated group and 47 in the control group) were analyzed in the study. Moderate to severe regurgitation was found in 15 patients treated with pergolide (17.4%) and in 2 control subjects (4.3%) (odds ratio [OR], 4.75; 95% confidence interval [CI], 1.02-22.1; P = .03). Moderate to severe regurgitation was associated with the cumulative dose of pergolide (OR, 1.37; 95% CI, 1.04-1.81 per 10-mg/kg increase; P =.03). Including the present study, the meta-analysis comprised 7 trials (394 patients treated with pergolide and 280 controls). The overall OR for moderate to severe regurgitation was 3.1 (95% CI, 1.7-5.6; P < .001) in the pergolide-treated group. Risk differences were correlated with the mean cumulative dose of pergolide (r = 0.90, P < .001). DATA SOURCES: Using an end point of moderate to severe heart valve regurgitation, we performed a meta-analysis of patients having Parkinson disease (PD) treated with pergolide mesylate vs control subjects by searching PubMed (January 1, 1966, to April 1, 2007) and the Cochrane databases to identify English-language prospective observational studies that reported echocardiographic data. CONCLUSION: Heart valve disease is independently associated with the use of pergolide treatment in patients having PD and correlates with its cumulative dose.
