Heart attacks were once thought of as a disease of age – but worrying new data shows they are increasing in healthy young adults.Roughly 0.3 percent of Americans aged 18-44 had a heart attack in 2019 – but last year that rose to 0.5 percent, or one in 200.While that may still seem like a relatively low number, it represents a 66 percent increase in cases in just four years, which doctors call ‘alarming.’ It also means that one in five heart attack patients are now younger than 40.
