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).

Mental stress in HF patients leads to increase in heart rate, blood pressure

Mental stress among heart failure patients led to a significant increase in heart rate and diastolic and systolic blood pressure in a study of patients who prepared and gave a speech about their personal strengths and weaknesses.

More than 10% of patients hospitalized for HF have worsening symptoms

Approximately 10 percent to 15 percent of patients had worsening heart failure or died within five days of being admitted into a hospital for acute heart failure, according to a pooled analysis of clinical trials.

Wine may improve spirits but not outcomes for heart failure patients

Moderate wine consumption may lighten the outlook for patients with chronic heart failure but it may not make any difference in long-term outcomes, based on results from a large Italian study.

Cognitive decline is common after LVAD implantation

Nearly one-third of patients had cognitive decline one year after undergoing left ventricular assist device (LVAD) implantation for advanced heart failure, according to an analysis of a large, multicenter, observational registry

Low health literacy associated with increased risk of death in acute HF patients

Patients with acute heart failure had an increased risk of all-cause mortality after being discharged from the hospital if they had a low level of health literacy, according to a retrospective study. After adjusting for various factors, the risk of death for patients with low health literacy was 32 percent higher than for patients with higher health literacy.

Success in Heart Failure: Keeping Patients Free of Hospitals

Some implantable cardiac devices capture data that may indicate worsening health in patients with heart failure. Cardiologists are beginning to use that information to identify at-risk patients and intervene before their conditions deteriorate and require hospitalization.
