Heart failure is a condition in which the heart has lost the ability to pump enough blood to the body’s tissues. With too little blood being delivered, the organs and other tissues do not receive enough oxygen and nutrients to function properly.
Heart failure is a common endpoint for many cardiovascular diseases. This syndrome is characterized by reduced cardiac output that leads to dyspnea, exercise intolerance and later death. More than 20 million people worldwide are estimated to have heart failure. And, this situation will get worse since the prevalence of heart failure will rise as the … Read more
Disrupting an antioxidant pathway prevents heart disease caused by reductive stress – Researchers have found that deficiency of an antioxidant response protein called nuclear erythroid-2 like factor-2 (Nrf2) delays or prevents hypertrophic cardiomyopathy, a type of a heart failure in which the heart muscle grows abnormally thick.
Pacemaker could help more heart failure patients – A new study from Karolinska Institutet demonstrates that a change in the ECG wave called the QRS prolongation is associated with a higher rate of heart-failure mortality. According to the team that carried out the study suggests that more heart failure cases could be helped by pacemakers.
Popular antidepressant might prevent heart failure – A medication usually used to help treat depression and anxiety disorders has the potential to help prevent heart failure. John Tesmer, research professor at the U-M Life Sciences Institute and professor in the Department of Pharmacology at the U-M Medical School, and his research team at the Tesmer lab found that paroxetine, a selective serotonin reuptake inhibitor (SSRI) sold under the name Paxil, inhibits G protein-coupled receptor kinase 2 (GRK2), a protein kinase that becomes over-expressed when people have heart failure.
Regular, moderate, coffee drinking may reduce heart failure risk — Yes, moderate coffee consumption offers protection against heart failure – If you drink coffee regularly in moderation, you could reduce your risk of heart failure. Researchers, analyzing previous studies on the link between coffee consumption and heart failure, found that moderate coffee drinking as part of a daily routine may be linked with a significantly lower risk of heart failure. In contrast, indulging excessively may be linked with an increased chance of developing serious heart problems.
Testosterone supplements may help heart failure patients – Testosterone supplements helped heart failure patients breathe better and exercise more. This new research analyzed four randomized clinical trials of patients with moderate to severe chronic heart failure. Patients were given commercial testosterone supplements by injection, patch or gel.
Healthy lifestyle habits lower heart failure risk – If you don’t smoke, aren’t overweight, get regular physical activity and eat vegetables, you can significantly reduce your risk for heart failure, according to research reported in Circulation: Heart Failure, an American Heart Association journal.
Heart failure risk lower in women who often eat baked/broiled fish – The risk of developing heart failure was lower for postmenopausal women who frequently ate baked or broiled fish, but higher for those who ate more fried fish, in a study reported in Circulation: Heart Failure, an American Heart Association journal.
Low Health Literacy Associated With Higher Rate of Death Among Heart Failure Patients – An examination of health literacy (such as understanding basic health information) among managed care patients with heart failure, a condition that requires self-management, found that nearly one in five have low health literacy, which was associated with a higher all-cause risk of death.
Therapy to prevent heart failure more effective in women than men — Never before has a therapy proven more beneficial for women than men in preventing heart disease ? until now. – Women receive a significantly greater benefit ? a 70 percent reduction in heart failure and a 72 percent reduction in death ? from cardiac resynchronization therapy with defibrillator (CRT-D) than men, revealed by US researchers.
