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).

Researchers find new method to determine blood clot risks

Predicting when a patient is at risk for developing a blood clot can be challenging for physicians, but new research from Johns Hopkins University and Ohio State University delivers a method for precisely identifying those risk factors.

Heart failure expected to steadily rise through 2030

New statistics show the number of people diagnosed with heart failure will rise 46 percent by 2030, a major increase that would result in more than eight million people to be diagnosed with the condition, according to a new report from the American Heart Association.

Tackling Intolerance: What to Do When Patients Pull the Plug on Statins

Despite their well-documented benefits, statins are often discontinued by patients because of their equally acknowledged side effects. This has continued to fuel heated debate over how widespread—or even legitimate—these adverse events are, whether physicians give up too easily on patients who are statin intolerant and what other options exist for patients who could gain by taking their cholesterol-lowering medicine?

Researchers use 3D printing to create patch that reduces heart failure

Researchers from the University of Alabama at Birmingham and the University of Minnesota have developed a method to grow heart tissue that can reduce the likelihood of heart failure after a heart attack using 3D-printing technology.

New study on heart failure explores possibilities for personalized treatment

As more individuals are being diagnosed with heart failure, finding effective treatment methods is a priority for physicians and patients. A new study published in the scientific journal Nature Communications may have found a way to create a personalized treatment for the condition.

Experts explain challenges in studying CVD mortality in Hispanic subgroups

In response to a study published in JAMA Cardiology last week about a decrease in the number of Hispanics dying from cardiovascular disease, three physicians wrote a commentary explaining the challenges in concluding those findings.

Soft robot could aid failing hearts by mimicking healthy cardiac muscles

Every year about 2,100 people receive heart transplants in the United States, while 5.7 million suffer from heart failure. Given the scarcity of available donor hearts, clinicians and biomedical engineers from Boston Children's Hospital and Harvard University have spent several years developing a mechanical alternative.

Heart attacks increased in New Orleans after Hurricane Katrina

In the decade since Hurricane Katrina, cardiologists in New Orleans have noticed an uptick in the number of patients suffering from heart attacks.
