Creatinine Bumps and Renal Tubular Injury in Acute Heart Failure
In patients with acute heart failure who receive aggressive diuresis, worsening renal function identified by a rise in serum creatinine or cystatin C is not indicative of kidney tubular injury.

Is the Type of Myocardial Infarction Important?
An observational study of hospitalized patients with type 1 or 2 myocardial infarction (MI) or myocardial injury showed that mortality is higher in type 2 MI or myocardial injury patients compared to type 1 MI patients.

Vegetarian Diet vs. Mediterranean Diet to Reduce Cardiovascular Risk
A randomized, open, cross-over study of a vegetarian diet (VD) compared to the Mediterranean diet (MD) over three months showed that both reduced body weight and body fat mass. The VD decreased LDL cholesterol, and MD reduced triglyceride levels. The MD reduced inflammatory markers, and the VD reduced vitamin B12 levels.

Prognostic Value of Left Ventricular Strain in Chronic Aortic Regurgitation
A retrospective observational study of the incremental value of echocardiographic global longitudinal strain (GLS) for predicting mortality in asymptomatic patients with moderate to severe aortic regurgitation and normal left ventricular function showed that GLS was a predictor of mortality. However, GLS was not as robust as undergoing surgery was for predicting mortality.

Is It Acceptable to Die of Aortic Stenosis Without a TAVR?
Investigators performed a retrospective analysis of 544 patients undergoing transcatheter aortic valve replacement (TAVR) at one center to assess the contribution of a frailty score to the Society of Thoracic Surgeons (STS) risk score for predicting mortality post-procedure. The frailty score was found to be an independent predictor of 30-day and one-year mortality and additive to the STS score.
