Heart Failure

Caffeine appears to do the opposite of what you might think when it comes to the heart. Scientists have found that a cup of coffee a day actually protects the heart from atrial fibrillation – a condition that can lead to stroke and heart failure.

In a breakthrough for diagnostics, scientists have created an effective and easy test that identifies a heart failure biomarker in saliva, opening the door to more rapid and accessible life-saving medical interventions for this disease – and others.

People living in areas of higher air pollution are at risk of more serious sleep apnea events, according to a large study spanning multiple countries. However, being aware of air quality means you can mitigate that risk to improve sleep and health.

The US Food and Drug Administration (FDA) has approved the first intranasal diuretic for heart, liver and kidney disease patients, aiming to prevent a common and costly issue that results in more than a million hospitalizations each year.

A new study has presented what is called the Adipokine Hypothesis, suggesting one of the most common forms of heart failure may stem from biological changes in internal fat; sending out chemical signals that stir up inflammation.

For the first time, surgeons have successfully performed a heart transplant in which the donor organ never skips a beat, limiting muscle damage and improving acceptance and recovery. It ushers in a new era of our approach to this lifesaving operation.

If someone is afflicted with heart disease, it's important that their cardiac activity be monitored as accurately as possible. An experimental new wearable device is designed to make that happen, by copying the body structure of the starfish.

A man has lived for more than 100 days with a maglev heart beating inside his chest. In a landmark moment, he was discharged earlier this year, becoming the first person in the world to leave the hospital with the device embedded in his body.

Heart attacks are dangerous not just because of the initial event, but the long-term damage afterwards. Now scientists have discovered a dormant gene that could be reactivated to regenerate heart tissue, preventing the progression to heart failure.

Scarring of heart tissue can be slowed but not stopped, and can lead to heart failure. But a new study has shown that an existing immunotherapy could stop scar tissue formation after heart attacks.

Examining long-term outcomes for people with atrial fibrillation, the most common heart rhythm disorder, a new study found that 55% survived to 10 years. The researchers say it needs to be treated as a chronic illness with serious long-term consequences.

Detecting the first stages of heart failure could soon be as simple as placing a smartphone on a patient's chest. That's the conclusion of an ongoing study, which is aimed at developing an app for diagnosing the potentially lethal condition as early as possible.
