Heart attack

In an analysis of the sleep habits of over 72,000 people, researchers identified a particular pattern that can dramatically spike the risk of major cardiovascular problems. The good news is that the pattern is relatively easy to avoid.

Finding time to exercise each day is a challenge for many people, but a new study of nearly 15,000 men and women has discovered that adding just five minutes of daily activity that gets your heart rate up is enough to lower your blood pressure.

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.

A tiny chip with a unique surface can accurately detect the blood biomarkers of a heart attack within minutes, a fraction of the time taken by current methods. The researchers behind the device see it being used as an at-home diagnostic tool.

Sticky plaques building up on the walls of your blood vessels can lead to heart attacks and strokes. Now, a new nanoparticle infusion therapy has been found to break down these plaques safely in tests in pigs.

Placing defibrillator pads on the chest and back, rather than the usual method of putting two on the chest, increases the odds of surviving an out-of-hospital cardiac arrest by more than two-and-a-half times, according to a new study.

A new injectable, temporary pacemaker could help correct a heart arrhythmia in an emergency. This nanoparticle gel can regulate the heart’s electrical signals for up to five days before dissolving harmlessly in the body.

Smoking, obesity, and stress. They're all common causes of damaging cardiac events. However, a just-published study says a new culprit should be added to the list of the risks that can hurt our hearts: constipation.

It turns out that blasting people with shockwaves during open-heart surgery is a really good idea. That's what researchers found who used the technique to reactivate heart cells and improve the post-op lives of patients in a groundbreaking study.

Even brief periods of anger caused by triggering memories can negatively impact our blood vessels' ability to relax. That's the finding of a new study that could have implications on how we look at heart attack and stroke risk.

Researchers suggest the 1918 influenza pandemic caused a wave of heart disease in the 20th century. With new evidence showing the impact of COVID on our hearts, could this recent pandemic be setting us up for another century of cardiac problems?

A new pacemaker is thinner than a human hair, wireless and operated entirely by light from an optic fiber. The non-invasive device could help regulate heart activity or even stimulate neurons in a set pattern to treat conditions like Parkinson’s.
