Regular Exercise in Middle Age Can Build Heart Muscle
April 08, 2011

Exercising at least 4 times a week can increase left ventricular mass and preserve elasticity, thereby reducing the risk of diastolic heart failure. Researchers from Texas presented their study results at the American College of Cardiology’s 60th Annual Scientific Session.

Pulse Pressure May Be Clue to White Coat Hypertension
April 08, 2011

Measurement of pulse pressure may help identify patients with "white coat" hypertension, according to data presented by Korean researchers at the American College of Cardiology’s 60th Annual Scientific Session.

Shorter Antiplatelet Regimen Sufficient After Stenting
April 08, 2011

What is the optimal duration for antiplatelet therapy after placement of drug-eluting stents? Initial results of the EXCELLENT study show that 6 months of antiplatelet therapy is as effective as the 12-month regimen recommended by current guidelines.

Chronic Heart Failure Outcomes Not Improved by NT-proBNP-Guided Treatment
April 06, 2011

A Danish study found no clinical benefit from using NT-proBNP (b-type natriuretic peptide) to identify and monitor high-risk patients with chronic heart failure, according to research from the NorthStar study presented at the American College of Cardiology’s 60th Annual Scientific Session in New Orleans.

CABG Bests Medical Therapy in Ischemic Heart Failure
April 06, 2011

Compared with medical therapy alone, coronary artery bypass grafting (CABG) significantly reduced cardiovascular deaths and the composite end point of all-cause deaths and cardiovascular-related hospitalizations, reported investigators from the Surgical Treatment of Ischemic Heart Failure (STICH) trial. However, the effect of the two management strategies on overall survival in patients with ischemic heart failure was similar.

What’s the Evidence Behind Updated ACC/AHA Guidelines on Unstable Angina/Non-STEMI?
April 05, 2011

Recently, the American College of Cardiology (ACC) and the American Heart Association (AHA) released a focused update to the 2007 guidelines for the management of patients with unstable angina (UA)/non-ST-elevation myocardial infarction (non-STEMI).

Resistant Hypertension: Four Pearls for Your Practice
April 05, 2011

A panel of experts presented a general strategy for evaluating patients with refractory hypertension, but ultimately cautioned the audience to assume non-compliance until proven otherwise.

Heart Failure With Preserved Ejection Fraction: Lessons From Three Cases
April 04, 2011

The panel presented three challenging cases of heart failure with preserved ejection fraction (HFPEF) (see Update on Diastolic Heart Failure). In an innovative twist, the panel solicited feedback from a standing-room-only audience through SmartPhone technology-attendees voted for their favored diagnostic approach, therapy, or final diagnosis, with voting results instantly integrated into the presenter’s Powerpoint display.

Update on Diastolic Heart Failure-and Implications for Primary Care
April 04, 2011

Diastolic heart failure (or HFPEF-heart failure with preserved ejection fraction) is characterized by inadequate myocardial relaxation and diastolic filling ("stiff ventricle"), with heart failure signs and symptoms despite normal ejection fraction. The most common cause is long-standing hypertension.

Elevated C-Reactive Protein Predicts Myocardial Deterioration
April 04, 2011

Systemic inflammation has been identified as a risk factor for the development of heart failure in population studies. In the 5-year prospective MESA study, researchers from Johns Hopkins Hospital in Baltimore recorded a baseline nonspecific marker of systemic inflammation, C-reactive protein (CRP).
