Insights into the Association of Atrial Fibrillation and Myocardial Infarction
Given the mounting evidence suggesting that stroke, MI, and AF have pathophysiologic mechanisms in common, the presence of any one should at a minimum heighten suspicion for the others.

The Echo Calcium Score
Aortic valve sclerosis and mitral annular calcification detected by echocardiography are known to be associated with atherosclerosis and are predictive of cardiovascular morbidity and mortality.

Antibiotic Prophylaxis Guidelines and Endocarditis Rates
Despite the limitations of this type of study, it supports the U.S. view of treating high-risk patients with antibiotic prophylaxis.

Endovascular Intervention Takes Center Stage in Treatment of Acute Stroke
Two studies join a growing body of recent evidence supporting improved clinical outcomes with interventional treatment of acute stroke.

Valve Thrombosis After TAVR: Is It as Rare as We Thought?
A CT study demonstrates that valve thrombosis may be more common than earlier thought.

FDA Approves Ivabradine for Systolic Heart Failure
ABSTRACT & COMMENTARY: In HF patients with a heart rate above 70 bpm, despite truly maximum-tolerated doses of beta-blockers, ivabradine is an option.

Athlete’s Heart vs Brugada ECG
The normal variant ECG seen predominantly in highly trained athletes of domed ST segment elevation, and negative T waves in V1-V3 can be confused with some of the ECG patterns in Brugada syndrome patients.

Cardiac Sarcoidosis: Rare or Underdiagnosed?
There is increasing evidence that sarcoidosis can be confined to the heart, but disagreements abound about the diagnosis and treatment of cardiac sarcoidosis (CS).

SIMPLE Is Better – ICD Defibrillation Testing Does Not Improve Outcomes
Traditionally, the placement of an implantable cardioverter-defibrillator (ICD) concludes with induction of ventricular fibrillation (VF) to confirm that the new device is able to appropriately sense the arrhythmia and terminate it while there is still the opportunity to reposition the ventricular lead or add an additional lead if necessary.

Are Atrial Premature Complexes Benign?
Atrial premature complexes (APCs) are commonly observed on routine ECGs and believed to be harbingers of atrial fibrillation, especially in patients with cardiovascular disease.
