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).

Georgia hospital begins providing routine cardiac care to cancer patients

In a new initiative at Northeast Georgia Medical Center in Gainesville, cancer patients are being screened for heart conditions, a byproduct of cancer treatments that arise in some patients, reports the Gainesville Times.

Breastfeeding could reduce chance of heart disease, stroke in women

Breastfeeding has long been considered a healthy choice for both mothers and their babies, but new research published this week shows that it could also reduce a woman’s risk of having a heart attack or stroke later in life.

Transportation noise could contribute to cardiovascular disease

Noise from aircrafts, rail and road traffic could be negatively impacting the cardiovascular health of people regularly exposed to it, according to researchers in Switzerland.

Eating healthy fats, not saturated fats, could lower cardiovascular risks

Eating healthier fats, like avocados and nuts, instead of saturated fats commonly found in many meats, could lower cardiovascular disease risk as much as cholesterol-lowering statin drugs, according to the American Heart Association (AHA).

Arthritis drug shows promise in combatting protein that causes aortic valve stenosis

Development of a drug to help those suffering from rheumatoid arthritis may prove to be quite a happy accident for aging individuals with hardening heart valves. Researchers from Vanderbilt University announced promising results in examining a monoclonal antibody’s ability to combat aortic valve stenosis.

Do mortality rates differ according to baseline heart rates for those taking beta-blockers?

It’s known beta-blockers reduce morbidity and mortality in those with heart failure with reduce left ventricular ejection fraction (HFrEF) in sinus rhythm. But questions remain about the roles baseline and achieved heart rates play in patients on beta-blockers and those with concomitant atrial fibrillation (AFib).

Sleeping in on weekends might be bad for the heart

A new study from the University of Arizona finds that sleeping in after a late night out could increase the chances of developing heart disease, reports Newsweek.

Machine learning mines EHRs to predict heart failure

The widespread implementation of electronic health records (EHRs) has proved to be a bumpy ride for many. But the sheer amount of data available in digital form carries with it plenty of potential. Recent work by scientists from IBM and Sutter Health developed artificial intelligence that can uncover pre-diagnostic heart failure through EHRs.
