Women who are at risk for breast cancer may also be at greater risk for heart disease, new research has found. http://medicalxpress.com/news/2011-12-breast-cancer-heart-disease-common.html Genetics Tue, 20 Dec 2011 13:56:08 EST news243611753 A low-calorie diet eliminates insulin dependence and leads to improved heart function in obese patients with type 2 diabetes, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). http://medicalxpress.com/news/2011-11-restricted-calorie-diet-heart-function.html Cardiology Mon, 28 Nov 2011 01:04:21 EST news241664402 Healthy, new heart cells have been generated by animals with chronic ischemic heart disease after receiving stem cells derived from cardiac biopsies or "cardiospheres," according to research conducted at the University at Buffalo School of Medicine and Biomedical Sciences. http://medicalxpress.com/news/2011-11-heart-cells-percent-stem-cell.html Cardiology Tue, 15 Nov 2011 11:09:31 EST news240577765 After a heart attack, the portions of the heart damaged by a lack of oxygen become scar tissue. Researchers have long sought ways to avoid this scarring, which can harden the walls of the heart, lessen its ability to pump blood throughout the body and eventually lead to heart failure. But new research from the University of North Carolina at Chapel Hill School of Medicine shows that interrupting this process can weaken heart function even further. http://medicalxpress.com/news/2011-11-scarring-evil-heart.html Cardiology Tue, 15 Nov 2011 10:40:36 EST news240576023 NIH-funded trial shows that therapy with bone-marrow derived cells does not improve heart function after six months; future clinical benefits still possible. http://medicalxpress.com/news/2011-11-stem-cell-therapy-heart-safe.html Cardiology Mon, 14 Nov 2011 09:26:22 EST news240485170 A wearable defibrillator can prevent sudden death in people with dangerous heart arrhythmias, according to research presented at the American Heart Association's Scientific Sessions 2011. http://medicalxpress.com/news/2011-11-wearable-defibrillator-death-people-arrhythmias.html Cardiology Sun, 13 Nov 2011 12:14:44 EST news240408834 A UCSF study holds clues to why an emerging clinical trials option for heart attack patients has not been as successful as anticipated. Treatment of human hearts with bone marrow cells has led to limited to no success in improving their heart function even though a similar method has been much more effective in rodents. http://medicalxpress.com/news/2011-09-weakness-heart-therapy.html Cardiology Tue, 20 Sep 2011 12:04:44 EST news235739068 UCLA researchers have found that the hormone estrogen may help reverse advanced pulmonary hypertension, a rare and serious condition that affects 2 to 3 million individuals in the U.S., mostly women, and can lead to heart failure. http://medicalxpress.com/news/2011-09-estrogen-treatment-reverse-severe-pulmonary.html Diseases, Conditions, Syndromes Thu, 15 Sep 2011 13:07:13 EST news235310805 A follow-up of participants in a heart function study finds that the prevalence of left ventricular diastolic dysfunction (left ventricular filling [with blood] is abnormal and is accompanied by elevated filling pressures) had increased; that diastolic function had worsened in a nearly a quarter of patients; and that participants who had diastolic dysfunction were more likely to develop heart failure, according to a study in the August 24/31 issue of JAMA. http://medicalxpress.com/news/2011-08-diastolic-dysfunction-worsen-heart-failure.html Cardiology Tue, 23 Aug 2011 16:54:35 EST news233337266 After a heart attack or stroke, heart scarring can lead to dangerously paper-thin heart walls and a decreased ability to pump blood through the body. Although the heart is unable to completely heal itself, a new treatment developed at Tel Aviv University uses laser-treated bone marrow stem cells to help restore heart function and health. http://medicalxpress.com/news/2011-08-heart-lasers-stem-cells-scarring.html Medical research Thu, 11 Aug 2011 02:59:14 EST news232250338 Few studies have examined the acute effects of alcohol on myocardial or heart function. While moderate-to-high blood concentrations of alcohol acutely impair conventional echocardiographic measures of left ventricular (LV) performance, the effects of low concentrations are unclear. An examination of the acute effects of low blood concentrations of alcohol on the left and right ventricles, which collectively pump blood to the entire body, has found that low doses of alcohol can have very different effects on LV and right ventricular (RV) function. http://medicalxpress.com/news/2011-07-amounts-alcohol-effects-left-ventricles.html Health Fri, 15 Jul 2011 17:40:01 EST news229967256 Patients treated with sunitinib and sorafenib responded to the flu vaccine, which suggests the agents do not damage the immune system as much as previously feared, according to a study in Clinical Cancer Research, a journal of the American Association for Cancer Research. http://medicalxpress.com/news/2011-06-patients-sunitinib-sorafenib-flu-vaccine.html Cancer Tue, 28 Jun 2011 13:34:01 EST news228486567 Heart function may be affected in people with Type 2 diabetes as early as adolescence, according to a new study that will be presented Sunday at The Endocrine Society's 93rd Annual Meeting in Boston. http://medicalxpress.com/news/2011-06-teens-diabetes-impaired-heart-function.html Cardiology Tue, 07 Jun 2011 10:42:57 EST news226661753 A promising cancer treatment drug can restore function of a heart en route to failure from high blood pressure, researchers at UT Southwestern Medical Center have found. http://medicalxpress.com/news/2011-05-drug-reverse-overgrown-hearts-heart.html Medical research Tue, 31 May 2011 03:49:20 EST news226032542 For women with breast cancer undergoing radiation therapy, yoga offers unique benefits beyond fighting fatigue, according to new research from The University of Texas MD Anderson Cancer Center. http://medicalxpress.com/news/2011-05-yoga-breast-cancer-patients.html Cancer Wed, 18 May 2011 18:20:39 EST news224961624 (PhysOrg.com) -- Human trials of stem cell therapy for post-heart attack patients have raised as many questions as they have answered -- because while the patients have tended to show some improvement in heart function, the stem cells do not appear to turn into heart cells or even survive. http://medicalxpress.com/news/2011-04-heart-stem-cells.html Medical research Fri, 08 Apr 2011 08:47:21 EST news221471227
