Patients who underwent coronary artery bypass graft surgery and had elevated levels of the cardiac enzymes creatine kinase or troponin in the 24 hours following surgery had an associated intermediate and long-term increased risk of death, according to a study in the February 9 issue of JAMA. http://phys.org/news216405779.html Medicine & Health Tue, 08 Feb 2011 16:43:23 EST news216405779 An analysis of data on more than 45,000 patients who underwent coronary artery bypass graft (CABG) surgery at an academic medical center over the past 30 years finds that the occurrence of stroke after CABG has declined, despite an increase in risk profiles of patients, according to a study in the January 26 issue of JAMA. http://phys.org/news215196566.html Medicine & Health Tue, 25 Jan 2011 16:49:41 EST news215196566 Coronary syndromes vary in severity, ranging from unstable angina, non-ST segment elevation myocardial infarction (NSTEMI), to ST-segment elevation myocardial infarction (STEMI), the most severe diagnosis. Little data exist about changing trends in acute myocardial infarction and whether death rates are increasing or decreasing. In a study published in the January 2011 issue of The American Journal of Medicine, investigators found that STEMI rates decreased and one-year post-discharge death rates decreased in NSTEMI and STEMI patients. http://phys.org/news214057782.html Medicine & Health Wed, 12 Jan 2011 12:30:19 EST news214057782 (PhysOrg.com) -- UC San Diego Health System is enrolling a small group of patients in a two-year study to examine the safety of a non-invasive cardiac shock wave procedure for patients with chest pain caused by insufficient blood flow to the heart. http://phys.org/news193504075.html Medicine & Health Wed, 19 May 2010 16:20:01 EST news193504075 The announcement of a new clinical trial, EXCEL (Evaluation of Xience Prime versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization), that will compare drug-eluting stents to coronary artery bypass graft surgery in patients with left main coronary artery disease, was made today at "Optimizing PCI Outcomes: Evolving Paradigms," a symposium presented by the Cardiovascular Research Foundation. http://phys.org/news187764455.html Medicine & Health Sun, 14 Mar 2010 06:10:01 EST news187764455 Patients who received telephone-delivered collaborative care for treatment of depression after coronary artery bypass graft surgery reported greater improvement in measures of quality of life, physical functioning and mood than patients who received usual care, according to a study in the November 18 issue of JAMA.
