This 'Super EKG' Could Diagnose Heart Disease in 90 Seconds

For many adults, moderate or severe chest pain can have some very sinister connotations. Fearing it's a sign of an imminent cardiac event like a heart attack, sufferers head to the emergency room for a diagnosis. In most cases, the chest pain is not life-threatening, but that's determined only after a series of expensive and time-consuming tests like an EKG, treadmill test, and blood work.

That may soon change, thanks to an enterprising 22-year-old college dropout. Peeyush Shrivastava and his biotech company Genetesis have engineered a body-sized 3D scanner called Faraday that creates a digital composite of the heart. The device looks at the magnetic fields surrounding the organ during normal cardiac activity, a process known as magnetocardiography. Shrivastava says the software, using various algorithms, can determine whether a person is having a cardiac event.

Genetesis says that after a patient submits to the scan—which is noninvasive, has no radiation, and takes roughly 90 seconds—technicians can examine the 3D rendering and be alerted to problems relating to lack of blood flow or coronary artery disease. By the time the results are evaluated, a patient could be discharged within four hours, eliminating the need for an overnight stay.

Chest pain is a leading cause of brief emergency room visits for adults over 45, with only 6 percent of the 8 million visits annually resulting in a diagnosis of heart attack. Reducing the time it takes to process these patients would reduce health care spending, ease patient anxiety, and provide more rapid intervention in the case of a cardiac event.

Genetesis is currently conducting trials of the technology at St. John's Hospital and Medical Center in Detroit. Once that's completed, the company will likely pursue a larger study with the eventual goal of FDA approval. It could be years before the device is in regular use, but if Genetesis's projections are accurate, it will be well worth the wait.

Crocs have long been a favorite among healthcare workers who spend hours on their feet each day—and now, they can get a pair for free.

This week, the company announced that it will give away more than 100,000 pairs of shoes to medical professionals fighting the new coronavirus in the U.S. ClickOrlando reports that workers can submit their requests for Crocs Classic Clogs or Crocs at Work via an online form on the Crocs website, which will open each weekday at 12 p.m. EST and continue accepting orders until it fulfills its daily allotment.

According to a press release, that allotment is a whopping 10,000 pairs of shoes per day. The as-yet-unspecified end date for the program—called “A Free Pair for Healthcare”—depends on inventory levels and the number of requests the company receives. In addition to shipping shoes to individuals, Crocs is also planning to donate up to 100,000 more pairs directly to healthcare organizations. So far, they’ll send shoes to the Dayton Area Hospital Association in Ohio, St. Anthony North Health Campus in Denver, Colorado, the Atlantic Health System in New Jersey, and more.

“These workers have our deepest respect, and we are humbled to be able to answer their call and provide whatever we can to help during this unprecedented time,” Crocs president and CEO Andrew Rees said in the release. “Share the word to all those in healthcare and please be mindful to allow those who need these most to place their requests. This is the least we can do for those working incredibly hard to defeat this virus.”

On This Day in 1953, Jonas Salk Announced His Polio Vaccine

On March 26, 1953, Dr. Jonas Salk went on CBS radio to announce his vaccine for poliomyelitis. He had worked for three years to develop the polio vaccine, attacking a disease that killed 3000 Americans in 1952 alone, along with 58,000 newly reported cases. Polio was a scourge, and had been infecting humans around the world for millennia. Salk's vaccine was the first practical way to fight it, and it worked—polio was officially eliminated in the U.S. in 1979.

Salk's method was to kill various strains of the polio virus, then inject them into a patient. The patient's own immune system would then develop antibodies to the dead virus, preventing future infection by live viruses. Salk's first test subjects were patients who had already had polio ... and then himself and his family. His research was funded by grants, which prompted him to give away the vaccine after it was fully tested.

Clinical trials of Salk's vaccine began in 1954. By 1955 the trials proved it was both safe and effective, and mass vaccinations of American schoolchildren followed. The result was an immediate reduction in new cases. Salk became a celebrity because his vaccine saved so many lives so quickly.

Salk's vaccine required a shot. In 1962, Dr. Albert Sabin unveiled an oral vaccine using attenuated (weakened but not killed) polio virus. Sabin's vaccine was hard to test in America in the late 1950s, because so many people had been inoculated using the Salk vaccine. (Sabin did much of his testing in the Soviet Union.) Oral polio vaccine, whether with attenuated or dead virus, is still the preferred method of vaccination today. Polio isn't entirely eradicated around the world, though we're very close.

Here's a vintage newsreel from the mid 1950s telling the story:
