Heart Failure

Heart failure occurs when the heart cannot pump as much blood as the body requires. This ineffective pumping can lead to enlargement of the heart as the myocardium works harder pump the same amount of blood. Heart failure may be caused by defects in the myocardium, such as an a heart attack infarct, or due to structural issues such as severe heart valve regurgitation. Heart failure can be divided into HF with preserved ejection fraction (HFpEF), and HF with reduced ejection fraction (HFrEF). The disease is further divided into four New York Heart Association (NYHA) classes. Stage IV heart failure is when the heart is completely failing and requires a heart transplant or hemodynamic support from a left ventricular assist device (LVAD).

Polyunsaturated fatty acids have no association with cardiovascular mortality

After adjusting for several cardiovascular risk factors, researchers found that none of the four major polyunsaturated fatty acids were associated with cardiovascular mortality in men from Sweden who enrolled in a prospective cohort study. However, linoleic acid was inversely associated with all-cause mortality.

Thousands of heart failure patients in the UK not receiving recommended treatment

As heart disease remains a pressing issue for many patients, identifying ways to avoid heart failure are at the forefront of physicians’ efforts.

Adults have increased prevalence of cardiovascular risk factors years before atrial fibrillation diagnosis

Adults with atrial fibrillation have an increased prevalence of cardiovascular risk factors such as stroke, MI and heart failure years before they are diagnosed with the condition, according to an analysis of a large, community-based cohort.

Scientists develop injectable gels that could prevent heart failure

Heart attacks cause severe damage to the heart, which over time can lead to heart failure. It can be hard to anticipate and even more difficult to prevent, but a new medical product may be able to help.

Transitional care interventions may improve outcomes following hospital discharge for heart failure

A systematic review from the Agency for Healthcare Research and Quality (AHRQ) suggests transitional care interventions may reduce all-cause readmissions and mortality rates among patients with heart failure.

Heart health can depend on job type

A recent study from the Centers for Disease Control and Prevention found that some jobs put you at higher risk for cardiovascular disease than others. 

Patients with heart failure and improved or recovered ejection fraction may have improved outcomes

A retrospective cohort study found that patients with heart failure and improved or recovered ejection fraction (HFrecEF) had lower mortality rates and less frequent hospitalizations compared with patients with heart failure and reduced ejection fraction or preserved ejection fraction.

Flu vaccines associated with 24 percent all-cause death reduction in type 2 diabetes patients

For adults with type 2 diabetes, the benefits of getting a seasonal flu vaccine go beyond avoiding an annoying infection. Vaccine recipients were admitted to the hospital at significantly lower rates for many cardiovascular and respiratory problems and were 24 percent less likely to die of any cause when compared to type 2 diabetes patients who did not get a vaccine.
