Abstract IMPORTANCE: The optimal management of severe mitral valve regurgitation in patients without class I triggers (heart failure symptoms or left ventricular dysfunction) remains controversial in part due to the poorly defined long-term consequences of current management strategies. In the absence of clinical trial data, analysis of large multicenter registries is critical. OBJECTIVE: To ascertain the comparative effectiveness of initial medical management (nonsurgical observation) vs early mitral valve surgery following the diagnosis of mitral regurgitation due to flail leaflets. DESIGN, SETTING, AND PARTICIPANTS: The Mitral Regurgitation International Database (MIDA) registry includes 2097 consecutive patients with flail mitral valve regurgitation (1980-2004) receiving routine cardiac care from 6 tertiary centers (France, Italy, Belgium, and the United States). Mean follow-up was 10.3 years and was 98% complete. Of 1021 patients with mitral regurgitation without the American College of Cardiology (ACC) and the American Heart Association (AHA) guideline class I triggers, 575 patients were initially medically managed and 446 underwent mitral valve surgery within 3 months following detection. MAIN OUTCOMES AND MEASURES: Association between treatment strategy and survival, heart failure, and new-onset atrial fibrillation. RESULTS: There was no significant difference in early mortality (1.1% for early surgery vs 0.5% for medical management, P=.28) and new-onset heart failure rates (0.9% for early surgery vs 0.9% for medical management, P=.96) between treatment strategies at 3 months. In contrast, long-term survival rates were higher for patients with early surgery (86% vs 69% at 10 years, P < .001), which was confirmed in adjusted models (hazard ratio [HR], 0.55 [95% CI, 0.41-0.72], P < .001), a propensity-matched cohort (32 variables; HR, 0.52 [95% CI, 0.35-0.79], P = .002), and an inverse probability-weighted analysis (HR, 0.66 [95% CI, 0.52-0.83], P < .001), associated with a 5-year reduction in mortality of 52.6% (P < .001). Similar results were observed in relative reduction in mortality following early surgery in the subset with class II triggers (59.3 after 5 years, P = .002). Long-term heart failure risk was also lower with early surgery (7% vs 23% at 10 years, P < .001), which was confirmed in risk-adjusted models (HR, 0.29 [95% CI, 0.19-0.43], P < .001), a propensity-matched cohort (HR, 0.44 [95% CI, 0.26-0.76], P = .003), and in the inverse probability-weighted analysis (HR, 0.51 [95% CI, 0.36-0.72], P < .001). Reduction in late-onset atrial fibrillation was not observed (HR, 0.85 [95% CI, 0.64-1.13], P = .26). CONCLUSION AND RELEVANCE: Among registry patients with mitral valve regurgitation due to flail mitral leaflets, performance of early mitral surgery compared with initial medical management was associated with greater long-term survival and a lower risk of heart failure, with no difference in new-onset atrial fibrillation.

Abstract OBJECTIVE: To assess whether lithium has a specific preventive effect for suicide and self harm in people with unipolar and bipolar mood disorders. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Medline, Embase, CINAHL, PsycINFO, CENTRAL, web based clinical trial registries, major textbooks, authors of important papers and other experts in the discipline, and websites of pharmaceutical companies that manufacture lithium or the comparator drugs (up to January 2013). INCLUSION CRITERIA: Randomised controlled trials comparing lithium with placebo or active drugs in long term treatment for mood disorders. REVIEW METHODS: Two reviewers assessed studies for inclusion and risk of bias and extracted data. The main outcomes were the number of people who completed suicide, engaged in deliberate self harm, and died from any cause. RESULTS: 48 randomised controlled trials (6674 participants, 15 comparisons) were included. Lithium was more effective than placebo in reducing the number of suicides (odds ratio 0.13, 95% confidence interval 0.03 to 0.66) and deaths from any cause (0.38, 0.15 to 0.95). No clear benefits were observed for lithium compared with placebo in preventing deliberate self harm (0.60, 0.27 to 1.32). In unipolar depression, lithium was associated with a reduced risk of suicide (0.36, 0.13 to 0.98) and also the number of total deaths (0.13, 0.02 to 0.76) compared with placebo. When lithium was compared with each active individual treatment a statistically significant difference was found only with carbamazepine for deliberate self harm. Lithium tended to be generally better than the other active comparators, with small statistical variation between the results. CONCLUSIONS: Lithium is an effective treatment for reducing the risk of suicide in people with mood disorders. Lithium may exert its antisuicidal effects by reducing relapse of mood disorder, but additional mechanisms should also be considered because there is some evidence that lithium decreases aggression and possibly impulsivity, which might be another mechanism mediating the antisuicidal effect.

Abstract The causes of death within 1 year of hospital admission in patients with non-ST-segment elevation acute coronary syndromes are ill defined, particularly in patients aged ≥75 years. From January 2008 through May 2010, we enrolled 645 patients aged ≥75 years with non-ST-segment elevation acute coronary syndromes: 313 in a randomized trial comparing an early aggressive versus an initially conservative approach, and 332, excluded from the trial for specific reasons, in a parallel registry. Each death occurring during 1 year of follow-up was adjudicated by an independent committee. The mean age was 82 years in both study cohorts, and 53% were men. By the end of the follow-up period (median 369 days, interquartile range 345 to 391), 120 patients (18.6%) had died. The mortality was significantly greater in the registry (23.8% vs 13.1%, p = 0.001). The deaths were classified as cardiac in 94% of the cases during the index admission and 68% of the cases during the follow-up period. Eighty-six percent of the cardiac deaths were of ischemic origin. In a multivariate logistic regression model that included the variables present on admission in the whole study population, the ejection fraction (hazard ratio 0.95, 95% confidence interval 0.94 to 0.97; p <0.001), hemoglobin level (hazard ratio 0.85, 95% confidence interval 0.76 to 0.94; p = 0.001), older age (hazard ratio 1.05, 95% confidence interval 1.01 to 1.10, p = 0.010), and creatinine clearance (hazard ratio 0.99, 95% confidence interval 0.97 to 0.99; p = 0.030) were the independent predictors of all-cause death at 1 year. In conclusion, within 1 year after admission for non-ST-segment elevation acute coronary syndromes, most deaths in patients aged ≥75 years have a cardiac origin, mostly owing to myocardial ischemia.
