Apple just announced a new Watch called Apple Watch Series 4. The new Apple Watch comes with a larger, edge-to-edge screen, giving it the biggest facelift since its launch in 2014. The screen is 30 percent larger than the previous version, while the device itself has become thinner.

Taking a low-dose aspirin every day has long been known to cut the chances of another heart attack, stroke or other heart problem in people who already have had one, but the risks don't outweigh the benefits for most other folks, major new research finds.

Two thirds of cases of deadly heart failure are being missed by GPs - amid warnings that an NHS target culture is fuelling a “medical emergency”. Leading cardiac experts said women and older patients were faring worst, amid “dangerous” failures to spot the life-threatening condition which can be treated with cheap pills.

A common drug used to control blood pressure and help prevent heart failure is being recalled in 22 countries because it contains a chemical that poses a potential cancer risk. Valsartan is off-patent and is used as a component of other generic medicines. Novartis, the company that originally developed the drug, said Sandoz valsartan and valsartan/HCT film-coated tablets are being recalled since they "do not meet our high quality standards."

The first pacemaker hacks emerged about a decade ago. But the latest variation on the terrifying theme depends not on manipulating radio commands, as many previous attacks have, but on malware installed directly on an implanted pacemaker. For nearly two years, researchers Billy Rios of the security firm Whitescope and Jonathan Butts of QED Secure Solutions have gone back and forth with pacemaker manufacturer...

A new blood test can help emergency room doctors more quickly determine whether patients with chest pain are having a heart attack. The test is a more sensitive version of one that emergency physicians have been using. The conventional troponin test takes three hours, the high-sensitivity version can give results in less than an hour. High-sensitivity troponin tests have been available in Europe and elsewhere for years. But the first such test in the United States was just approved last year.

A new study published in the journal Lancet has indicated that we may have been demonising salt a little too much.

New research reignites a row with scientists who want to reduce salt intake to near zero

A Harvard scientist thinks he's reached a new milestone: a genetic test that helps identify people who are at high risk of having a heart attack. Can he convince doctors to use it? "I think--in a few years, I think everybody will know this number, similar to the way we know our cholesterol right now," muses Sekar Kathiresan, director of the Cardiovascular Disease Initiative at the Broad institute and a professor at Harvard Medical School.

Young adults with healthy blood pressure go on to have better thinking and memory skills in midlife than their peers with higher blood pressure, according to a new analysis. Previous studies have linked poor fitness and heart health in middle age to declining mental function and dementia around age 70 or 80

Though we’ve known about the connection for some time, a large-scale study hints at the degree to which depression may increase the risk of future heart disease. Looking at data from almost 63,000 people in Norway, and following up over 11 years, the researchers found that mild depression was linked to a 5% increase in the risk of heart failure in the future. Moderate to severe depression was linked to a surprisingly high 40% rise in the risk.

The new study's conclusion shouldn't surprise anyone familiar with modern nutritional science, however. The fact is, there has never been solid evidence for the idea that these fats cause disease. We only believe this to be the case because nutrition policy has been derailed over the past half-century by a mixture of personal ambition, bad science, politics and bias.

On the heels of research suggesting too much running could lead to an earlier death, two new studies say too much high-intensity exercise could lead to heart problems.

Obesity is on track to overtake smoking as the most common risk for heart disease in Canada by 2015, according to a study published Tuesday. “Obesity is a major problem in Canada, affecting nearly one in five adults,” said lead author and Ottawa Hospital Research Institute senior scientist Dr. Doug Manuel.

Scientists believe they have an explanation for the axiom that stress, emotional shock, or overexertion may trigger heart attacks in vulnerable people. Hormones released during these events appear to cause bacterial biofilms on arterial walls to disperse, allowing plaque deposits to rupture into the bloodstream, according to research published in published in mBio®, the online open-access journal of the American Society for Microbiology.

Feeling angry? Let it all out, punch a pillow, blow off steam, but don’t keep it in, right?

Study finds that people who reduced carbs saw bigger drop in risk factors for heart disease.

Twice now, surgeons in Australia have revived a dead heart—a heart that had stopped beating—and brought it back to life before transplanting it into a new person. It’s a huge breakthrough that could potentially save 30 percent more lives compared to ordinary heart transplants, according to the surgeons who performed this feat.

A ground-breaking bionic heart without a pulse is hoped to be saving lives within three years. The world-first device was designed by Brisbane engineer Dr Daniel Timms, who instigated the project in 2001 while studying at the Queensland University of Technology. It recently passed its biggest test when it was successfully transplanted into a live and healthy sheep, and Dr Timms now wants it ready for human trials by 2018.

This award-winning 3-D model of the heart isn't just a feat of science, it'll help you better understand your own body.

This trip in the NPR Books Time Machine, we're rewinding Richard Kadrey's hardboiled supernatural noir series about a half-angel, half-human man who fights crime and occasionally saves the world.

Cardiac disease is the world’s leading cause of death. Cardiac Disease's pathogenesis is largely attributed to cholesterol, predominantly carried by low-density lipoproteins(LDL).However, recent research has found that oxidized-LDL is significantly more potent in the initiation and development of atherosclerosis. Tests for both cholesterol and ox-LDL tests are lab-based and expensive. With every third American at risk for Cardiac Disease, this research aims to produce an on-site, ultra-low cost.

Steve Williams couldn’t breathe. The former athlete had cardiomyopathy, which occasionally choked his lungs with fluid, making him gasp for air. But this felt different; Williams felt like he was dying. He was raced to an Orange County hospital, and shortly after checking in, his heart stopped. For 30 minutes, ER workers compressed his chest in an attempt to revive him. At one point, his wife Mary remembers being called into his room to say goodbye to...

Prinzmetal’s angina is a form of chest pain, pressure, or tightness (angina) caused by spasms in the arteries that supply blood to the heart.

Is a temporary discomfort or pain that is caused by a temporary spasm in one or more of your coronary arteries (the arteries that supply oxygen and nutrients to your heart).

CONTROVERSIAL heart drug statins have been linked to almost twenty thousand reports of side effects and 227 deaths.

Most characteristic and common signs and symptoms of thyroid disease are those that result from the effects of thyroid hormone on the heart and cardiovascular system

When your heart breaks … (Literally).“You can die of a broken heart — it's scientific fact. A sudden temporary weakening of the muscular portion of the heart, this weakening can be triggered by emotional stress, such as the death of a loved one, a break-up, or constant anxiety, it is also known as broken-heart syndrome.

John McCafferty, the world's longest-living heart transplant recipient, has died 33 years after his operation. His surgeon, Sir Magdi Yacoub, said that he hadn't thought the donor heart would last more than five years. John's wife, Ann, said that they had had a wonderful life together but that John had been very ill before his operation.

It was way past midnight, and she still couldn't fall asleep..

What looks like a prop from a steampunk movie is actually a partially decellularised heart in a bioreactor.

Visionary street artist Lonac is the talented individual behind this impressive hand-painted heart. He strategically placed his design between the air ducts which flow in and out of the building. By doing so he created the illusion of the aorta that passes blood through the heart itself.
