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).

Can a genetic mutation kill heart disease? Not so fast

A recent New York Times article asked if a genetic mutation could be the key to wiping out heart disease. Dutch professor John Kastelein, PhD, MD, said it could be the final nail in the coffin of heart disease. But John LaMattina, PhD, former president of Pfizer Global Research, says everybody needs to take a deep breath.

Methamphetamine abusers regain heart function after quitting

Methamphetamine abuse significantly increases one’s morbidity leading to complications such as arrhythmias, hypertension and methamphetamine-associated cardiomyopathy (MACM).

New paper strip test can detect heart failure

Scientists from China have developed a new paper strip test that could allow heart failure patients to monitor their condition at home.

Predictive models for heart failure, sudden death ID patients unlikely to benefit from ICDs

Implantable cardioverter defibrillators (ICDs) have been proven effective in reducing mortality in patients with severe systolic heart failure. A recent study used two models—one for heart failure and another for proportional risk—to identify patients less likely to benefit from ICDs.

Weight-loss surgery shown to cut heart failure risk in half

In a new study led by researchers at Geisinger Obesity Institute in Danville, Pennsylvania, investigators were surprised when they saw overwhelming evidence that weight-loss surgery decreased long-term risks of heart failure by more than half in obese patients.

COPD episodes could increase chance of heart attack, stroke in heart patients

New research presented at the American Thoracic Society conference in San Francisco has provided evidence that people with chronic obstructive pulmonary disease (COPD) or have a history or risk for cardiovascular disease more often suffer from heart attack and stroke.

New tablet device detects heart failure, provides assistance

Researchers from Linkoping University in Sweden have developed a tablet device that can help treat heart failure patients, reports DNA.
