High estimated pulmonary artery systolic pressure (ePASP) has been established as a detrimental predictor for adverse outcomes in patients with chronic kidney disease. However, the relation between preoperative high ePASP and the development of cardiac surgery associated acute kidney injury (CSA-AKI) has not been validated. We performed a retrospective cohort study of adult patients who underwent valve surgery in 2015 at Zhongshan Hospital, Fudan University. ⋯ Preoperative ePASP more than 60 mm Hg was found to be linked with the increasing incidence of AKI by 62% and in-hospital mortality by over 300%, but not linked with severe AKI or renal replacement therapy. In conclusion, an increase in preoperative ePASP was independently and significantly associated with the development of CSA-AKI in patients who underwent valve surgery. Such relation between preoperative ePASP and CSA-AKI could provide a novel therapeutic target against prevention of AKI.

Candidates for transcatheter aortic valve implantation (TAVI) are generally older with multiple co-morbidities and are therefore susceptible to nonelective admissions before scheduled TAVI. Frequency, predictors, and outcomes of TAVI after nonelective admission are under-explored. We queried the Nationwide Inpatient Sample database, an administrative database, from January 2012 to September 2015 to identify hospitalization in those age ≥50 who had transarterial TAVI. ⋯ Nonelective admission accounted for approximately one-fifth of total TAVI with significantly different cohort profiles. Our results suggest that nonelective TAVI has higher adverse outcomes and increased health resource utilization. Expedition in TAVI process in high-risk cohorts may result in better outcomes.

A significant proportion of patients with acute myocarditis experience sudden cardiac death presumably due to cardiac arrhythmia. In this study, we explore the burden, the predictors of arrhythmia in acute myocarditis and the association between arrhythmias and adverse in-hospital outcomes. After evaluating the frequency of various tachyarrhythmias and bradyarrhythmia in myocarditis population, we built a logistic model to determine the independent predictors of arrhythmias in myocarditis and a 1:1 propensity-matched analysis to examine the impact of arrhythmias. ⋯ Length of stay and cost of hospitalization were also significantly higher. A significant proportion of patients with myocarditis have cardiac arrhythmias. As the occurrence of arrhythmias in myocarditis is associated with worse outcomes, it may be important to risk stratify patient to identify those who will benefit from early intervention.

Multicenter Study Comparative Study
Comparison of Incidence, Predictors, and Outcomes of Early Infective Endocarditis after Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement in the United States.
Infective endocarditis (IE) of prosthetic or bioprosthetic heart valves is a serious complication associated with significant morbidity and mortality. Data on the incidence, risk factors, and outcomes of IE after transcatheter aortic valve implantation (TAVI) in the United States are limited. We used the 2013 to 2014 Nationwide Readmissions Databases to determine the incidence of early IE after TAVI and surgical aortic valve replacement (SAVR) in the US. ⋯ In-hospital mortality rate during readmission for IE was 15.6%. In conclusion, in a nationally representative cohort of TAVI patients in the US, the incidence rate of early IE was 1.7% per person-year. Age, co-morbid conditions, invasive procedures, and complications during the index hospitalization were associated with incident IE post-TAVI.

Randomized Controlled Trial Multicenter Study
Usefulness of Rivaroxaban for Secondary Prevention of Acute Coronary Syndrome in Patients With History of Congestive Heart Failure (from the ATLAS-ACS-2 TIMI-51 Trial).
Patients with both acute coronary syndromes (ACS) and congestive heart failure are at an increased risk of recurrent cardiovascular (CV) events attributed in part to both excess thrombin generation and impaired fibrinolysis. We hypothesized that patients with the overlap of ACS and CHF would thus derive particular benefit from antithrombotic therapy with rivaroxaban. ATLAS-ACS-2 Thrombolysis in Myocardial Infarction-51 was a double-blind, multicenter, phase 3 clinical trial that randomized patients within 7 days of an ACS event to standard of care plus either rivaroxaban 2.5 mg BID, 5 mg BID, or placebo (n = 15,526). ⋯ Rivaroxaban also did not increase either intracranial hemorrhage or fatal bleeding. In conclusion, in ACS subjects with a history of CHF, secondary prevention with rivaroxaban reduced the composite of CV death, myocardial infarction, or stroke without an increase in noncoronary artery bypass graft-related major bleeding. These findings require further prospective evaluation in an adequately powered phase 3 study.
