Heart Tissue Shows Signs of Aging After Just One Month in Space, Study Finds

Scientists sent bioengineered heart tissue samples to the ISS to study how to keep astronauts safe during future long-term space travel

The findings build on research from last year, which found that people with higher levels of the sweetener in their blood were at a greater risk of heart attacks and strokes.

Common Artificial Sweetener Linked to Increased Heart Attack Risk in Small Study

Healthy people who consumed 30 grams of the sweetener erythritol had an increased risk of blood clot formation, while people who consumed the same amount of glucose did not

Akira Endo discovered the first statin, a class of molecule that decreases the production of cholesterol. He died June 5 at the age of 90.

Akira Endo, Biochemist Who Found a Way to Fight Heart Disease, Dies at 90

Endo's research paved the way for the development of drugs to treat high cholesterol and reduce the risk of heart attacks or strokes

Previous research suggested that anger can increase people's risk of heart attacks. In the new study, researchers found that part of the reason why could be that anger briefly reduces blood vessels' ability to widen.

Can Anger Affect Your Heart Health? Scientists Find the Strong Emotion Impacts How Blood Vessels Function

The results could even help explain why stress from anger may trigger a heart attack

Doctors perform a pig kidney transplant on April 12. So far, the patient is recovering well, but doctors will need to continue to monitor her in the hospital and make sure her immune system doesn't reject the transplanted organ.

Second Patient Receives Gene-Edited Pig Kidney Transplant in Breakthrough Surgery

The woman, 54-year-old Lisa Pisano, also received a mechanical heart pump implant days earlier, making her the first person to undergo both procedures

Around 40 percent of people experience a fainting spell at some point in their lives.

Here's What Causes Fainting, According to New Research

Scientists have discovered a pathway between the heart and brain in mice that appears to be involved during loss of consciousness

A new generation of blood pressure measuring devices that don’t require an inflatable cuff around the arm may make it easier to manage hypertension.

New Devices Could Change the Way We Measure Blood Pressure

Embedded in a cellphone or in accessories such as rings, bracelets or watches, the novel tools aim to make it easier to manage hypertension

Study participants experienced cardiac arrest while in the hospital and received CPR in an attempt to resuscitate them.

Scientists Search for Near-Death Experiences of Cardiac Arrest Patients

Through survivor interviews and brain scans during CPR, researchers looked for evidence of awareness when people's hearts had stopped

Many organizations classify hypertension as a blood pressure reading of 140/90 mmHg or higher, though some say 130/80 mmHg.

High Blood Pressure Is a 'Silent Killer' That Affects One in Three People, WHO Says

But nearly half of those living with the condition don't know they have it, according to the organization's first report on hypertension

The Gogo fish fossil 

World's Oldest Vertebrate Fossil Heart Found in Australia

The 380-million-year-old heart came from a prehistoric fish that is our earliest jawed ancestor

Most individuals born male have an X and a Y chromosome, while those born female have two X chromosomes. 

Loss of Y Chromosome in Mice May Lead to Heart Failure

A new study suggests the same loss in humans may lead to increased mortality

Surgeon Bartley Griffith examines the pig heart before the transplant.

Why Did the First Human Patient to Receive a Pig Heart Transplant Die?

Scientists have come up with at least four explanations

Porcine Virus May Have Led to the Death of First-Ever Pig Heart Transplant Patient

Doctors say this infection will likely be preventable in future pig heart transplants

MIT researchers wove a fiber designed from a piezoelectric material with traditional yarn to create a machine-washable fabric. 

Researchers Create a Fabric That Can 'Hear' Your Heartbeat

This fabric acts as both a speaker and microphone, detecting even faint noises and converting them into electrical signals

Patient Who Received a Genetically Modified Pig Heart Dies After Two Months

The procedure marks the first time that a genetically-modified, non-human cardiac organ functioned without immediate rejection by the human body

Scientists built this synthetic fish using paper, plastic, gelatin and human heart cells.

Scientists Build an Artificial Fish That Swims on Its Own Using Human Heart Cells

The experiment could advance pacemaker technology and bring science closer to developing artificial hearts for people

Unable to attend the funeral, an Australian farmer made a video of sheep in the shape of a heart to express his grief for his aunt, who died after a two-year battle with cancer.

Australian Farmer Expresses Grief With 'Sheep Art' Heart

The sheepherder couldn't attend his aunt's funeral, so he made her a huge heart out of hundreds of sheep—and captured it all from above using drone footage

Neither the FDA nor the researchers would identify the brands tested for the study. They also are not advocating that pet owners discontinue using dog foods containing peas at this time.

Are Peas in Common Dog Foods Contributing to Canine Heart Disease?

At this time, the FDA is not advocating that pet owners discontinue using any specific brand. But studying legumes may lead scientists to the root cause

Giraffes are just as astonishing on the inside as they are to look at. Standing up to 19 feet tall, they require enormously high blood pressure to pump blood up to the head, yet they suffer few, if any, of the consequences that people with high blood pressure would.

The Cardiovascular Secrets of Giraffes

Because of their height, giraffes require scarily high blood pressures—yet they escape the massive health problems that plague humans with hypertension

Cardioids begin to pulse with a heartbeat after seven days of development.

This Lab-Grown Mini Heart Can Keep a Beat

The creation, called a cardioid, will help with the study of heart disease and the discovery of new medications
