A study of 4,248 RA patients found that TNF inhibitors reduced heart failure risk when disease activity was high. The treatment also protected the heart and vital organs by reducing inflammation.
A new study from Duke University Medical Center found that heart failure incidence declined among the very elderly, while overall cases rose due to an aging population. The study examined Medicare beneficiaries' claims between 1994 and 2003 and found a decline in heart failure rates among those aged 80-84 years old.
The number of elderly individuals newly diagnosed with heart failure has declined, but those already living with the condition have increased steadily since 1994. This study found a significant economic burden on Medicare due to an aging population.
Researchers found that leaky muscle cells cause fatigue in both marathoners and heart failure patients. An experimental drug that plugs the leak may provide relief from exhaustion for those with chronic heart failure.
A Saint Louis University study found that less than a quarter of physicians can accurately predict patients' six-month mortality from heart failure. The study highlights existing knowledge gaps and uncertainty among doctors about end-stage care options, including palliative measures and hospice referrals.
A new study found that combining coronary artery bypass grafting (CABG) with surgical ventricular restoration (SVR) reduces the likelihood of subsequent heart problems by 24%, compared to 55% for CABG alone. SVR improves heart function, enabling patients to stay active and participate in daily activities without exhaustion.

Older patients taking thiazolidinediones (TZDs) like rosiglitazone have a significantly increased risk of heart attack, congestive heart failure, and death compared to other hypoglycemic drugs. This study suggests that TZDs may cause more harm than good, particularly in older adults who are already at higher risk.

Researchers at Duke University Medical Center analyzed Medicare records of over 236,000 patients between 1999 and 2005, finding that men were two to three times more likely than women to receive implantable cardioverter-defibrillators. The study also revealed racial disparities in ICD use, with white men receiving the most devices.
Women are less likely to receive implantable cardioverter-defibrillators (ICDs) for the primary and secondary prevention of sudden cardiac death compared to men. According to a study published in JAMA, men are about 2-3 times more likely than women to receive ICDs within a year of entering the study.

A University of Alberta study found that rural Albertans' strong work ethic and sense of place can influence their decision not to seek medical help for congestive heart failure. This can lead to delayed diagnosis and treatment, with patients often waiting days or even weeks for symptoms to subside.
Research found that aerobic exercise, such as walking or bicycling, significantly improved ejection fraction and reduced heart size in patients with stable heart failure. In contrast, combining aerobic exercise with strength training showed no similar benefits.
