Effects of limiting fluid intake on clinical and laboratory outcomes in patients with heart failure : Results of a meta-analysis of randomized controlled trials.
The guidelines of the Scientific Societies of Cardiology recommend limiting fluid intake as a nonpharmacological measure for the management of chronic heart failure (HF). However, many patients with HF may suffer from severe thirst. A meta-analysis was performed to evaluate the effect of limiting fluid consumption based on various clinical and laboratory outcomes in patients with chronic HF. ⋯ In patients with HF, liberal fluid consumption does not seem to exert an unfavorable impact on HF rehospitalizations or all-cause mortality. Further randomized controlled trials are warranted to definitively confirm the present findings.

The Osborn wave is a deflection with a dome-shaped configuration at the R-ST junction of the electrocardiogram. It is mainly encountered in hypothermic states but is also recognized in other nonhypothermic conditions. ⋯ Most important is its arrhythmogenic potential especially when observed in patients with myocardial ischemia where it was found to be a precursor of malignant ventricular arrhythmias. Herein, we provide a comprehensive review of the history, causes, electrocardiographic and electrophysiologic characteristics, as well as diagnostic and prognostic significance of the Osborn wave.

The treatment of mitral regurgitation has changed in recent years because of improvements in the surgical treatment, in particular valve repair, and the advent of interventional techniques, mainly percutaneous edge-to-edge repair. Regardless of the technique used, better results are obtained for interventions in primary mitral regurgitation than in secondary mitral regurgitation, which remains a challenge. Further developments are expected in the future thanks to a better understanding of the epidemiology and the mechanisms of secondary mitral regurgitation, the development of interventional techniques, and a careful evaluation.
