Surgical patients who experience atrial fibrillation may see a doubled stroke risk in the months following their procedure, according to a new study published in JAMA.
Results from a new study suggest that atrial fibrillation (AF) may pose a significant threat to patients undergoing surgery, especially those having non-cardiac procedures.
In an analysis of more than 1.7 million patients, researchers found that perioperative AF was associated with twice the risk of stroke in patients who had non-cardiac surgery. Patients who underwent a cardiac procedure saw a 30% increase in their stroke risk.
An new study shows that transcatheter aortic valve-in-valve implantation may be an important option for a growing population of patients with deteriorating bioprosthetic implants, but outcomes depend strongly on how the previous valve is failed.
New research released this week provides more support for the use of transcatheter aortic valve-in-valve (VIV) implantation as a means of replacing previously implanted valves that have deteriorated over time.
A new study suggests that patients with less-severe forms of heart failure may benefit from proactive and preventive treatment with implantable cardioverter defibrillators.
MASSDEVICE ON CALL — New data on implantable cardioverter defibrillators suggests that devices may help even less-sick patients prolong their lives.
The implants are generally indicated for patients who have fairly severe deficiencies in the heart's left ventricle's ability to pump blood coming from the left atrium out to the aorta. Normal left ventricular ejection fraction, or LVEF, is generally defined as between 50%-70%. Lower rates are considered a sign of potential dysfunction or heart failure.
Patients who undergo only 3-month-regimens of dual antiplatelet therapy after receiving a drug eluting stent fare just as well as patients who get the usual 12 months, researchers report.
Patients getting drug-eluting stents may be able to cut their post-procedure blood thinner regimen by as much as 75%, according to study published this week in the Journal of the American Medical Assn.
A new study concludes that price-increases are "the culprit" in the ever-increasing cost of U.S. healthcare, dispelling the myth that increasing demand has driven higher spending.
A team of U.S. physicians joined forces to examine the rising cost of healthcare, concluding that rising prices play a major role in driving up national healthcare spending and that patients are ultimately getting the short end of the stick.
The Sapien replacement heart valve fares as well in the real world as it did during clinical trials, according to an analysis in the Journal of the American Medical Assn.
Early surgery for patients with severe mitral regurgitation beat watchful waiting, significantly increasing survival rates, according to a new study in the Journal of the American Medical Assn.
Patients with severe mitral regurgitation showed significantly better survival rates after early surgery, compared with a "watchful waiting" approach, according to a study published this week in the Journal of the American Medical Assn.
