Obstructive sleep apnea (OSA) and central sleep apnea (CSA) are not markedly decreased in heart failure (HF) patients managed with beta-blockers and spironolactone, reports a study in the March issue of Journal of Cardiac Failure , published by Elsevier. http://www.physorg.com/news160806571.html Medicine & Health Wed, 06 May 2009 05:30:00 EST news160806571 (PhysOrg.com) -- Eating salmon or other fatty fish just once a week helped reduce men`s risk of heart failure, a recent study shows, adding to growing evidence that omega-3 fatty acids are of benefit to cardiac health. Led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and reported in the April 22 online issue of the European Heart Journal, the study is one of the largest to investigate the association. http://www.physorg.com/news159636149.html Medicine & Health Wed, 22 Apr 2009 16:22:53 EST news159636149 Sleep is such an essential part of human existence that we spend about a third of our lives doing it -- some more successfully than others. Sleep disorders afflict some 50-70 million people in the United States and are a major cause of disease and injury. People who suffer from disturbed sleep have an increased risk of heart attack, stroke, hypertension, obesity, depression, and accidents. Nearly a fifth of all serious car crashes, in fact, are linked to sleeplessness. http://www.physorg.com/news159023422.html Other Sciences Wed, 15 Apr 2009 14:10:49 EST news159023422 Patients with heart disease who are subsequently diagnosed with depression are at greater risk for heart failure (HF), a condition in which the heart can't pump enough blood throughout the body, according to a new study published in the April 21, 2009, issue of the Journal of the American College of Cardiology. This study -the first to investigate the influence of depression after heart disease on the likelihood of developing HF -also found that taking antidepressant medications to ease depressive symptoms did not appear to mitigate this risk. http://www.physorg.com/news158864057.html Medicine & Health Mon, 13 Apr 2009 17:54:40 EST news158864057 (PhysOrg.com) -- Adding to the growing evidence that a person`s waist size is an important indicator of heart health, a study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has found that larger waist circumference is associated with increased risk of heart failure in middle-aged and older populations of men and women. http://www.physorg.com/news158423763.html Medicine & Health Wed, 08 Apr 2009 15:36:37 EST news158423763 Many diseases derive from problems with cellular respiration, the process through which cells extract energy from nutrients.
