Heart

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

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

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

Spindly legs and thick, red fur have earned maned wolves the nickname “foxes on stilts,” but the animal is neither fox nor wolf.

What the Rhythm of a Maned Wolf's Heart Reveals

Smithsonian researchers are monitoring stress rates of this keystone species for better ways to manage them

Cases of MIS-C are very rare and are mostly popping up in COVID-19 hotspots

What Experts Know About a Rare Inflammatory Syndrome Linked to COVID-19

The syndrome resembles a childhood illness called Kawasaki disease, but research is ongoing about both conditions

New Study Shows Coffee—Even 25 Cups a Day of It—Isn't Bad for Your Heart

Researchers from Queen Mary University of London have found that coffee consumption does not stiffen arteries

In 1954, John Kirklin of the Mayo Clinic created the Mayo-Gibbon heart-lung machine when he modified a design pioneered by John Gibbon. The machine is now in the collection of the Smithsonian National Museum of American History.

This 1950s Heart-Lung Machine Revolutionized Cardiac Surgery

Open-heart procedures evolved rapidly once Mayo Clinic surgeon John Kirklin made his improvements to an earlier invention

Lead author Tal Dvir says, "Maybe, in ten years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely"

Scientists Used Human Tissue to 3-D Print a Tiny Heart

The technique could eventually be adapted to create full-sized organs personalized to each patient

In a feat of surgical skill, Denton Cooley attached the temporary artificial heart device in only 47 minutes.

The Rivalry Between Two Doctors to Implant the First Artificial Heart

Featuring titans of Texas medicine, the race was on to develop the cutting-edge technology

Compared to traditional open-heart surgery, TAVR is a relatively simple procedure that finds cardiologists using a catheter to insert a replacement valve

This Minimally Invasive Technique Could Reduce the Need for Open-Heart Surgery

Clinical trials suggest TAVR is just as beneficial as, or perhaps even better than, open-heart surgery for low- and high-risk patients alike
