In the wake of waking amidst the night to a fire in his home, the father of three helped his significant other and kids escape, saved the family pet and figured out how to recover vital family legacies from the consuming building. Be that as it may, later, at the doctor’s facility, Jack went into heart failure because of smoke inward breath. “It was cataclysmic, and I’m perplexed we’ve lost him,” a specialist revealed to Jack’s significant other, Rebecca.

While handing-off Jack’s demise to his closest companion Miguel, Rebecca later alluded to it as “a widowmaker’s heart assault.” Online looks for the expression spiked over 5,000% in the hours after the scene that uncovered Jack’s passing disclosed, and a few watchers took to web-based social networking to recount their own stories about friends and family who had kicked the bucket from—or survived—comparative occurrences.

In any case, what precisely is a widowmaker’s heart assault, and was the show’s depiction exact? To discover, TIME talked with Dr. Richard Katz, chief of the George Washington University Heart and Vascular Institute. This is what he says individuals should know in regards to coronary illness, sudden heart failure and the reasons for significant heart assaults.

What is a widowmaker’s heart assault?

At the point when specialists utilize the expression “widowmaker” to allude to a heart assault, they ordinarily aren’t discussing harm caused by smoke inward breath. Despite the fact that it’s not a specialized term, it ordinarily suggests a blockage of the left front plunging (LAD) conduit—the biggest of the three courses giving blood to the heart, likewise here and there called the widowmaker corridor.

The term is utilized on the grounds that these sorts of blockages are all the time lethal. “A widowmaker heart assault happens when that vein all of a sudden goes from 80% or 90% limited to 100% limited,” says Katz. “It happens rapidly, and all of a sudden you’re denying an expansive lump of that heart muscle from oxygen.”

This triggers a quick, hazardous heart beat called ventricular fibrillation, which makes individuals crumple from sudden heart failure. “Now and again this is transient and individuals wake go down,” he says. “Yet, when the blockage happens in the LAD, tragically this is the point at which we see sudden cardiovascular demise significantly more frequently.”

Blockages in the LAD course happen when plaque develops after some time. A less than stellar eating routine and stationary way of life are regularly enormous donors, yet widowmaker heart assaults can likewise happen in apparently sound individuals abruptly. Hereditary qualities can likewise assume a part.

Could smoke inward breath cause a widowmaker’s heart assault?

It’s conceivable that a sudden unpleasant occasion can add to this sort of heart assault, says Katz, if a man as of now has a fundamental blockage. (On This Is Us, specialists disclosed to Rebecca that smoke from the fire put a colossal measure of weight on Jack’s lungs and his heart, which made him go into heart failure. The character had no known history of cardiovascular issues.)

“Smoke inward breath will diminish oxygen to the body, which would make the heart work harder,” Katz says. “In the event that the heart is as of now attempting to get blood through a minor pinhole, it could deteriorate into a perilous circumstance.” a similar thing could likewise occur amid other upsetting circumstances, such as amid strenuous exercise or while scooping snow, he says.

It’s likewise conceivable that Jack did not have a fundamental blockage, and the show essentially expanded the utilization of the expression “widowmaker”. There are different ways smoke inward breath can cause heart failure and demise without really blocking blood stream to the heart—the specialized meaning of a heart assault.

“One might say, the word ‘widowmaker’ could allude to any type of sudden cardiovascular passing, in light of the fact that basically that is what it’s doing,” says Katz. “Did his circumstance fit this particular anatomical portrayal? Did they do a catheterization to check whether he had a blockage? We don’t have a clue, yet whichever way his significant other is as yet a dowager.”

What are the indications of a widowmaker heart assault?

Individuals with a blockage in their LAD corridor may encounter chest torment or snugness, and discombobulation, weariness, or shortness of breath amid physical effort. Sadly, be that as it may, there are at times no undeniable signs until the point that a heart assault happens.

Indications of a heart assault incorporate arm and chest torment, sweating and acid reflux or sickness. On account of a widowmaker heart assault, be that as it may, heart failure—and loss of awareness—quite often happens rapidly.

Will individuals recuperate from a widowmaker heart assault?

The survival rate from sudden heart failure is low: According to the American Heart Association, just around 12% of individuals who encounter heart failure out of the healing center, and around 25% who encounter it in the clinic, survive it.

Yet, a few people do make full recuperations. One critical factor in whether a man survives is access to incite therapeutic consideration—particularly, a gadget that can stun the heart once again into its typical cadence so it can keep pumping blood. (On account of a monstrous blockage, specialists will in any case need to work on the supply route, also.)

Last February, big name wellness coach Bob Harper endured a widowmaker heart assault while working out at his exercise center. He credits observers who immediately hopped vigorously, doing mouth to mouth and utilizing the exercise center’s mechanized outside defibrillator (AED), with sparing his life.

At the point when a man goes into heart failure in the clinic, the therapeutic staff for the most part endeavors revival with a defibrillator, too. That is another way This Is Us might not have been completely exact in its depiction of occasions, says Katz: For a youthful and solid individual like Jack, specialists would have likely spent longer attempting to restart his heart than the moment or two Rebecca was out of the room influencing a telephone to call.

“You couldn’t generally demonstrate this in 60 minutes in length TV program, yet, in actuality, the specialists would not stop after only three or five or ten minutes,” says Katz. “When somebody goes into heart failure in the doctor’s facility, we stun the patient, we perform mouth to mouth, and it can continue for 40 minutes or more. Everybody hops in, and we don’t surrender rapidly or effectively.”
