Study finds obese patients fair better than lean patients when hospitalized for acute heart failure
January 10, 2007Further evidence of the 'obesity paradox'
FINDINGS: Researchers report that for patients hospitalized with acute heart failure, a higher body mass index (BMI) was associated with a substantially lower in-hospital mortality rate. For every 5-unit increase in body mass, the odds of risk-adjusted mortality fell 10 percent. The finding held when adjusted for age, sex, blood urea nitrogen, blood pressure, and additional prognostic factors.
BACKGROUND: The study found that by weight category, in-hospital mortality rate was 6.3 percent for underweight, 4.6 percent for healthy weight, 3.4 percent for overweight and 2.4 percent for obese patients. "The study suggests that overweight and obese patients may have a greater metabolic reserve to call upon during an acute heart failure episode, which may lessen in-hospital mortality risk," said Fonarow. Obesity is a known risk factor for developing heart disease and heart failure and every effort should be made to avoid it, but once heart failure has manifested, this paradox seems to occur. Researchers utilized data on over 100,000 acute heart failure patient episodes, taken from the Acute Decompensated Heart Failure National Registry (ADHERE). The study and ADHERE is funded by Scios, Inc. The authors have received research grants and served as consultants for Scios.

Heart Failure Current Events and Heart Failure News RSSCarvedilol shown to have unique characteristics among beta blockers
In a new study, researchers report that a class of heart medications called beta-blockers can have a helpful, or harmful, effect on the heart, depending on their molecular activity.
High Blood Pressure Easy to Miss in Children with Kidney Disease
Spot blood pressure readings in children with chronic kidney disease often fail to detect hypertension - even during doctor's office visits - increasing a child's risk for serious heart problems, according to research from Johns Hopkins Children's Center and other institutions. A report of the findings appears online in the Journal of American Society of Nephrology.
Inhibition of GRK2 is protective against acute cardiac stress injuries
Inhibition of a protein known to contribute to heart failure also appears to be protective of the heart in more acute cardiac stress injury, namely ischemia reperfusion.
Young athletes need dual screening tests for heart defects, study suggests
To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins.
Protein changes in heart strengthen link between Alzheimer's disease and chronic heart failure
A team of U.S., Canadian and Italian scientists led by researchers at Johns Hopkins report evidence from studies in animals and humans supporting a link between Alzheimer's disease and chronic heart failure, two of the 10 leading causes of death in the United States.
Elevated biomarkers lead to diminished quality of life in heart attack patients post-discharge
Many heart attack patients have high levels of cardiac biomarkers in the blood for several months after leaving the hospital, with more shortness of breath and chest pain, according to a Henry Ford Hospital study.
Tiny particles can deliver antioxidant enzyme to injured heart cells
Researchers at Emory University and the Georgia Institute of Technology have developed microscopic polymer beads that can deliver an antioxidant enzyme made naturally by the body into the heart.
New study links vitamin D deficiency to cardiovascular disease and death
While mothers have known that feeding their kids milk builds strong bones, a new study by researchers at the Heart Institute at Intermountain Medical Center in Salt Lake City suggests that Vitamin D contributes to a strong and healthy heart as well - and that inadequate levels of the vitamin may significantly increase a person's risk of stroke, heart disease, and death, even among people who've never had heart disease.
When seconds count: Interventional radiology treatment for pulmonary embolism saves lives
Catheter-directed therapy or catheter-directed thrombolysis-an interventional radiology treatment that uses targeted image-guided drug delivery with specially designed catheters to dissolve dangerous blood clots in the lungs-saves lives and should be considered a first-line treatment option for massive pulmonary embolism, note researchers in the November Journal of Vascular and Interventional Radiology.

Heart Failure Heart failure, also called congestive heart failure, is a condition in which the heart cannot pump enough oxygenated blood to meet the needs of the body?s other organs. The heart keeps pumping, but not as efficiently as a healthy heart. Usually, the loss in the heart?s pumping action is a symptom of an underlying heart problem. Heart failure affects nearly 5 million US adults. It is on the rise with an estimated 400,000 to 700,000 new cases each year. This talk will focus on the causes, symptoms, diagnosis and treatments available for heart failure, including current research findings from Stanford. |

FlameEz-Heart, 60 Capsules/Bottle by FlameEz Conditions that damage the heart muscle or make it work too hard can cause heart failure. Over time, the heart weakens and certain inflammatory substances may be released into the blood, which have a toxic effect on the heart and cause heart failure to worsen. The most common causes of heart failure are coronary artery disease, high blood pressure, and diabetes, all of which are associated with chronic inflammation. Inflammatory cytokines suppress heart contractility, initiate hypertrophy and promote cell death or fibrosis. Results from a recent study land additional support that obesity causes prolonged inflammation of heart tissue that in turn boosts heart failure risk. New studies also suggest that modulation of inflammatory and immune responses may offer some hope to improve heart... |
