Yes, there’s been a rise in heart attacks in the young. I’ve yet to see a really good analysis of why, and I don’t plan to sit on a hot stove till I do. But one shouldn’t minimize the effects of COVID itself:
Los Angeles County paramedic Romeo Robles told TODAY in the Feb. 9 segment that upticks in COVID-19 would often lead to more 911 calls related to heart issues in his community.
“Surprisingly, people my age … we would find them in cardiac arrest, and it was all predicted by these waves,” he said.
Cheng called the connection “more than coincidental, that is for sure.” Explaining why, she pointed out that COVID-19 can greatly impact the cardiovascular system.
“It appears to be able to increase the stickiness of the blood and increase … the likelihood of blood clot formation,” Cheng said. “It seems to stir up inflammation in the blood vessels.
I only am able to read the abstract of the study, so it’s hard to say how rigorous it was. But if it’s anything like most of its kind, my guess is “not very rigorous at all.”
COVID isn’t the only contagious illness that can cause cardiovascular problems; even the flu can so so, for example. I’d like a study on cardiovascular problems that clearly distinguishes between the effects of vaccination and those of COVID itself, and that also makes previous decades-long trends in heart attack incidence clear. In addition, any study involving vaccines also has to deal with the fact that people who have been vaccinated tend to include a higher proportion of the most vulnerable populations: the elderly, the already-infirm, and those with cadiovascular risk factors such as obesity or prior heart defects. That must be corrected for or a study of the vaccinated is worthless.
Then there’s the whole issue of reporting relative risk in a population already at low risk, such as young people and cardiovascular problems. For example, a 30% increase in something that isn’t common to begin with tends to sound a lot worse than it is. For example, if something adverse happens to 1 in 1000 and its incidence increases by 30%, that means it then happens to 1.3 in 1000.
As for the issue of longer trends that began before COVID; see this (from March of 2019):
WASHINGTON (Mar 07, 2019) – Even though fewer heart attacks are occurring in the U.S.—in large part due to the use of medications like statins and a decline in smoking—these events are steadily rising in very young adults. New data not only validate this trend but also reveal that more heart attacks are striking those under age 40, according to research being presented at the American College of Cardiology’s 68th Annual Scientific Session.
The study, which is the first to compare young (41-50 years old) to very young (40 or younger) heart attack survivors, found that among patients who suffer a heart attack at a young age overall, 1 in 5 is 40 or younger. Moreover, during the 16-year study period (2000 to 2016), the proportion of very young people having a heart attack has been increasing, rising by 2 percent each year for the last 10 years.
“It used to be incredibly rare to see anyone under age 40 come in with a heart attack—and some of these people are now in their 20s and early 30s,” said Ron Blankstein, MD, a preventive cardiologist at Brigham and Women’s Hospital, associate professor at Harvard Medical School in Boston and the study’s senior author. “Based on what we are seeing, it seems that we are moving in the wrong direction.”…
In a related study, Blankstein and his team found that 1 in 5 patients who suffer a heart attack at a young age overall—defined as younger than 50 years of age—also have diabetes. Data show that if someone has diabetes they are more likely to die and have repeat events than heart attack survivors without diabetes. Not only is diabetes one of the strongest risk factors for having a heart attack, it also predicts future events in young people who have previously had a heart attack.
Type 2 diabetes has been on the rise in young people for decades, and it may be a strong factor in what’s going on.
