Intra-arterial therapy no more effective than IV t-PA in treating acute ischemic stroke

A stroke survivor's chances of living independently after 90 days are not improved by the use of devices inserted into the artery to dissolve or remove a stroke-causing clot shortly after the onset of symptoms, according to a randomized controlled trial involving 656 patients.

Performing angiography and cardiac surgery on the same day increases risk of acute kidney injury

Performing heart surgery on the same day as angiography is now confirmed as a risk factor for acute kidney injury (AKI), and hospital policy limiting the practice for elective cardiac surgery has significantly reduced the rate of AKI, according to a study published in the February 2013 issue of The Annals of Thoracic Surgery.

Treadmill test can accurately predict coronary artery disease in women over 65

Although there is a widespread belief among physicians that the exercise treadmill test (ETT) is not reliable in evaluating the heart health of women, UC Davis researchers have found that the test can accurately predict coronary artery disease in women over the age of 65. They also found that two specific electrocardiogram (EKG) indicators of heart stress during an ETT further enhanced its predictive power.

Drug-eluting stents exhibit some benefits in patients over 80

Rarely tested in patients over the age of 80, a study found that drug-eluting stents exhibited some benefits over bare-metal stents, though both types of stents demonstrated a clinical benefit. Results of the XIMA trial were presented today at the 24th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium.

Study finds decline in inpatient mortality rate for upper gastrointestinal hemorrhage in the U.S.

The number of patients dying from upper gastrointestinal bleeding has decreased over the past two decades, a result researchers attribute to the advances in medical and endoscopic therapies introduced over the past 20 years, according to a report unveiled today at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas.
