FIGHT study proves type-2 diabetes therapy ineffective in the treatment of high-risk heart failure patients In an attempt to correct defects in the energy generation that contributes to poor pump function among heart failure patients, researchers examined whether the diabetes drug liraglutide, could improve the condition of patients with advanced heart failure. Despite improvements in blood sugar control, the therapy did not improve the clinical stability or pumping action of the heart in patients with advanced heart failure. Kenneth B. Margulies, MD, a professor of Medicine and research director for Heart Failure and Transplantation in the Perelman School of Medicine at the University of Pennsylvania, presented data from the Functional Impact of GLP-1 for Heart Failure Treatment (FIGHT) study at the American Heart Association Scientific Sessions 2015.
Effectiveness of drug to improve natriuretic peptide levels for chronic heart failure Mihai Gheorghiade, M.D., of the Northwestern University Feinberg School of Medicine, Chicago, and colleagues randomly assigned 456 patients with worsening chronic HF and reduced left ventricular ejection fraction (a measure of how well the left ventricle of the heart pumps with each beat) to receive placebo or 1 of 4 daily target doses of the medication vericiguat for 12 weeks. This JAMA study is being released to coincide with its presentation at the American Heart Association's Scientific Sessions 2015.
Diagnosing and treating diabetes in heart attack patients improves heart outcomes, study finds People with heart problems often have diabetes, which puts them at greater risk for heart attacks, heart failure and stroke. Now, a new study has found that ensuring heart attack patients are promptly diagnosed and treated for diabetes makes a significant difference in improving their cardiac outcomes.
	Energy drink increases blood pressure, norepinephrine levels Anna Svatikova, M.D., Ph.D., of the Mayo Clinic, Rochester, Minn., and colleagues randomly assigned 25 healthy volunteers (age 18 years or older) to consume a can (480 mL; 16 fl. oz.) of a commercially available energy drink (Rockstar; Rockstar Inc) and placebo drink within 5 minutes, in random order on 2 separate days, maximum 2 weeks apart. The placebo drink, selected to match the nutritional constituents of the energy drink, was similar in taste, texture, and color but lacked caffeine and other stimulants of the energy drink (240 mg of caffeine, 2,000 mg of taurine, and extracts of guarana seed, ginseng root, and milk thistle). This JAMA study is being released to coincide with its presentation at the American Heart Association's Scientific Sessions 2015.

	Sudden cardiac arrest? Can't find an AED? There may be an app for that The earlier bystanders can deliver shocks with an automated external defibrillator (AED) to people who have cardiac arrest outside the hospital, the better their chances are for survival. Although it may be difficult to find community-based AEDs, a new smartphone application helps connect rescuers with lifesaving AEDs and victims with sudden cardiac arrest, according to research presented at the American Heart Association's Scientific Sessions 2015.
Studies address long-term health of living kidney donors While it's important to monitor the health of recipients following kidney transplantation, it's equally important to assess the ongoing health of living donors who have generously given up an organ. Several studies that will be presented at ASN Kidney Week 2015 November 3-8 at the San Diego Convention Center in San Diego, CA address various aspects of donor health.
