Alcohol Septal Ablation in Younger HCM Patients: Should We Relax Guidelines?
Current guidelines recommend surgical myectomy over septal ablation for younger hypertrophic cardiomyopathy patients. A new study bridges part of the data gap, showing safety and efficacy of the procedure in young patients.

Early Diuretic Administration Associated With Improved Survival in Acute Heart Failure Patients
Among patients presenting to the ED with acute heart failure, those who received the first dose of intravenous furosemide within 60 minutes of arrival demonstrated lower in-hospital mortality compared to those receiving the first dose after 60 minutes.

Prevention of Myocardial Infarction in Atrial Fibrillation Patients
A large observational study showed that the primary prevention of myocardial infarction and stroke in patients with atrial fibrillation is better with vitamin K antagonists alone as compared to aspirin alone and dual therapy.

Requiem for Beta-blockers Post-Myocardial Infarction?
A propensity score analysis of all hospital survivors of acute myocardial infarction in the United Kingdom from 2007-2013 showed that one-year survival in hospital patients without heart failure or left ventricular dysfunction treated with beta-blockers did not differ from survival in those patients not so treated.

Left Ventricular Volume Affects Function in Chemotherapy Patients
Reductions in left ventricular ejection fraction in patients receiving potentially cardiotoxic chemotherapy may be because of significant decreases in left ventricular volume in up to 20% of these patients.

B-type Natriuretic Peptide Is Less Useful in Elderly Patients With Dyspnea
Among patients ≥ 80 years of age presenting with acute dyspnea, B-type natriuretic peptide level was not useful for differentiating cardiac vs. respiratory etiologies when added to a model of clinical predictors.

Distinguishing Ischemic From Non-ischemic Cardiomyopathy Clinically
The authors of a recent study concluded that specific clinical and ECG abnormalities could be used to estimate which patients with reduced left ventricular ejection fraction were at low risk of having ischemic cardiomyopathy.

Antiplatelet Therapy After TAVR: More ARTE Than Science
The current clinical standard of dual antiplatelet therapy following transcatheter aortic valve replacement is controversial.

Late-breaking Clinical Trials from the Heart Rhythm Society May 2017 Scientific Sessions
Late-breaking findings of several important clinical trials were presented at this year’s Heart Rhythm Society Scientific Sessions in Chicago. A selection particularly relevant to the general cardiology community is presented here.

Value of Monitoring ECG Lead aVR in Exercise Stress Testing
Analysis of ST transients in aVR during exercise ECG testing can provide additional diagnostic information in patients suspected of having ischemic heart disease.
