Utility of Serial Coronary Calcium Scores
Researchers determined recently that if serial scans are performed, the most recent scan should be used for risk assessment, and the degree of CT calcium score progression adds no further prognostic information.

A New Risk Score for Stroke in Atrial Fibrillation
A new, simpler score for stroke risk prediction in atrial fibrillation patients uses biomarkers to supplant many clinical variables and outperforms the CHA2DS2-VASc score in two large cohorts.

Orbiting the Truth of Heart Failure Incidence and Implications in Those with Prevalent Atrial Fibrillation
Patients presenting with atrial fibrillation are at elevated risk for the development of heart failure, typically with preserved ejection fraction, which is associated with increased risk of death and hospitalization.

NOACs in Patients Requiring Anticoagulation Post-PCI
In patients with atrial fibrillation post-percutaneous coronary intervention with stent placement, recently studied regimens conferred a significantly lower risk of clinically important bleeding compared to standard triple therapy with full-dose warfarin.

Do the Benefits of a Bioabsorbable Coronary Scaffold Also Disappear Over Time?
In the longest-term randomized, controlled study of coronary bioresorbable vascular scaffolds to date, the Absorb bioresorbable vascular scaffold was outperformed by its metallic drug-eluting stent counterpart.

Ablation of the Left Atrial Appendage for Long-standing, Persistent Atrial Fibrillation
Addition of left atrial appendage ablation to pulmonary vein isolation, and extensive other ablation, improved freedom from atrial arrhythmias in patients with long-standing persistent atrial fibrillation without increasing complications.

Sacubitril/Valsartan Associated with Reduced Risk of Hyperkalemia
In a secondary analysis of the PARADIGM-HF trial, the risk of severe hyperkalemia in heart failure patients taking a mineralocorticoid receptor antagonist was lower among patients treated with sacubitril/valsartan compared to those receiving enalapril.

The Happy Heart Syndrome
Stress cardiomyopathy can be triggered by positive as well as negative emotions; the midventricular pattern of wall motion abnormality was more prevalent among happy hearts.

White-coat Hypertension:Does It Predict Cardiovascular Disease?
The risk of cardiovascular events in white-coat hypertension subjects is comparable to age and risk-adjusted normotensive controls.

Recently Diagnosed Idiopathic Dilated Cardiomyopathy Patients Are at Risk for Major Arrhythmic Events
Patients with recently diagnosed idiopathic dilated cardiomyopathy are at marked risk of major arrhythmia events that are neither well-predicted by traditional methods nor protected against by defibrillator implantation more than three months after diagnosis.
