Based on these findings, we postulate a new mechanism of cardiac toxicity based on the PTM-driven accumulation of desmin amyloid-like oligomers. Phosphorylation and cleavage as well as oligomers formation are reduced by treatment (CRT) indicating a relationship between the three. Finally, the decrease of desmin amyloid-like oligomers with CRT or small molecules points both to a general mechanism of HF based on desmin toxicity that is independent of protein mutations and to novel potential therapies.

BackgroundClinical evidence in coronary surgery is usually derived from retrospective, single institutional series. This may introduce significant biases in the analysis of critical issues in the treatment of these patients. In order to avoid such methodological limitations, we planned a European multicenter, prospective study on coronary artery bypass grafting, the E-CABG registry.DesignThe E-CABG registry is a multicenter study and its data are prospectively collected from 13 centers of cardiac surgery in university and community hospitals located in six European countries (England, Italy, Finland, France, Germany, Sweden). Data on major and minor immediate postoperative adverse events will be collected. Data on late all-cause mortality, stroke, myocardial infarction and repeat revascularization will be collected during a 10-year follow-up period. These investigators provided a score from 0 to 10 for any major postoperative adverse events and their rounded medians were used to stratify the severity of these complications in four grades. The sum of these scores for each complication/intervention occurring after coronary artery bypass grafting will be used as an additive score for further stratification of the prognostic importance of these events.DiscussionThe E-CABG registry is expected to provide valuable data for identification of risk factors and treatment strategies associated with suboptimal outcome. These information may improve the safety and durability of coronary artery bypass grafting. The proposed classification of postoperative complications may become a valuable research tool to stratify the impact of such complications on the outcome of these patients and evaluate the burden of resources needed for their treatment.Clinical Trials numberNCT02319083

Mitral valve replacement is a suitable option for patients with chronic ischemic mitral regurgitation and impaired left ventricular function. It provides better results in terms of freedom from reoperation with comparable valve-related complication rates.

This study provides contemporary data on the characteristics and outcome of patients undergoing first-time isolated aortic valve replacement.
