Background: Tricuspid regurgitation (TR) is associated with an increased mortality. Previous studies have analyzed predictors of TR progression and the clinical impact of baseline TR. However, there is a lack of evidence regarding the natural history of TR: the pattern of change and clinical impact of progression., Objectives: The authors sought to evaluate predictors of TR progression and assess the prognostic impact of TR progression., Methods: A total of 1,843 patients with at least moderate TR were prospectively followed up with consecutive echocardiographic studies and/or clinical evaluation. All patients with less than a 2-year follow-up were excluded. Clinical and echocardiographic features, hospitalizations for heart failure, and cardiovascular death and interventions were recorded to assess their impact in TR progression., Results: At a median 2.3-year follow-up, 19% of patients experienced progression. Patients with baseline moderate TR presented a rate progression of 4.9%, 10.1%, and 24.8% 1 year, 2 years, and 3 years, respectively. Older age (HR: 1.03), lower body mass index (HR: 0.95), chronic kidney disease (HR: 1.55), worse NYHA functional class (HR: 1.52), and right ventricle dilation (HR: 1.33) were independently associated with TR progression. TR progression was associated with an increase in chamber dilation as well as a decrease in ventriculoarterial coupling and in left ventricle ejection fraction (P < 0.001). TR progression was associated with an increased cardiovascular mortality and hospitalizations for heart failure (P < 0.001)., Conclusions: Marked individual variability in TR progression hindered accurate follow-up. In addition, TR progression was a determinant for survival regardless of initial TR severity., Competing Interests: Funding Support and Author Disclosures This study was supported by the Instituto de Salud Carlos III, PI20/01206.

Objective: Bleeding in ACS patients is an independent marker of adverse outcomes. Its prognostic impact is even worse in elderly population. Current bleeding risk scores include chronological age but do not consider biologic vulnerability. No studies have assessed the effect of frailty on major bleeding. The aim of this study is to determine whether frailty status increases bleeding risk in patients with ACS., Methods: This prospective and observational study included patients aged ≥75years admitted due to type 1 myocardial infarction. Exclusion criteria were severe cognitive impairment, impossibility to measure handgrip strength, cardiogenic shock and limited life expectancy due to oncologic diseases. The primary endpoint was 30-day major bleeding defined as a decrease of ≥3g/dl of haemoglobin or need of transfusion., Results: A total of 190 patients were included. Frail patients (72, 37.9%) were older, with higher comorbidity features and with a higher CRUSADE score at admission. On univariate analysis, frailty predicted major bleeding during 30-day follow-up despite less frequent use of a P2Y12 inhibitor (66.2% vs 83.6%, p=0.007) and decreased catheterisation rate (69.4% vs 94.1%, p<0.001). Major bleeding was associated with increased all-cause mortality at day 30 (18.2% vs 2.5%, p<0.001). On multivariate analysis, frailty was an independent predictor for major bleeding., Conclusion: Frailty phenotype, as a marker of biological vulnerability, is an independent predictor of major bleeding in elderly patients with ACS. Frailty can play an important role in bleeding risk stratification and objective indices should be integrated into routine initial evaluation of these patients., (Copyright © 2016 Elsevier Ireland Ltd.
