Of the 4,000 Americans waiting for heart transplants, only 2,500 will receive new hearts in the next year. Even for those lucky enough to get a transplant, the biggest risk is the their bodies will reject the new heart and launch a massive immune reaction against the foreign cells. To combat the problems of organ shortage and decrease the chance that a patient’s body will reject it, researchers have been working to create synthetic organs from patients’ own cells.

Study of remote communities in Venezuelan rainforest sheds fresh light on hypertension

New research shows that electronic cigarettes contain chemicals that cause heart damage, adding to the growing list of concerns about their safety. The study, which will be presented next Monday at the American Heart Association's Scientific Sessions meeting in Chicago, investigated the effect that e-cigarettes have on the endothelial cells that line the inside of the body's blood vessels. Endothelial cells produce nitric oxide, a molecule that helps keep blood vessels healthy and control blood pressure levels.

A vaccine may one day be able to replace oral blood thinners to reduce the risk of secondary strokes caused by blood clots, without increasing the risk of serious bleeding or triggering an autoimmune response, according to new research in the American Heart Association’s journal Hypertension.

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.

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.

A clip used to repair damaged heart valves sharply reduced deaths among patients with a grim prognosis.

Scientists know genes are responsible for roughly half your chance of having a heart attack, but they didn't know which genes were important. Now, in a huge world-first study, Australian scientists say they have discovered the DNA patterns that can raise our risk. People with high-risk DNA are more than four times more likely to have a heart attack than people with low-risk DNA, their study reveals.

Scientists are a big step closer to creating a fast, affordable DNA test to predict your risk of heart attack.

It also stores various biometric and location data, rousing inevitable privacy concerns.

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.

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.
