After decades of decline, fatal coronary heart disease may rise again unless Americans modify three major risk factors:
A Rutgers study just published in American Heart Journal found that deaths from coronary heart disease among people ages 25 to 84 dropped to 236,953 in 2019 from 397,623 in 1990, even though Americans’ median age increased to 38 from 33 over the last three decades.
Between 1990 and 2019, the US age-standardized coronary heart disease mortality rate per 100,000 fell from 210.5 to 66.8 for females (4 percent decline per year) and from 442.4 to 156.7 for males (3.7 percent decline per year).
However, the decline has slowed significantly since 2011. Those born after 1980 were actually at slightly increased risk of dying from coronary heart disease at any age than people from the previous generation.
The findings echo those from the same team’s investigation of stroke-related deaths in the US.
Rutgers researchers noted while future advances in treatment continue reducing fatal heart disease, complementary lifestyle modifications may play an important role. It estimated that the elimination of smoking, drinking, and obesity would have prevented half of the deaths observed during the study period.
Tobacco usage is already headed in the right direction: The percentage of Americans who smoked tobacco fell to 14 percent in 2019 from 26 percent in 1990. Obesity rates, on the other hand, rose sharply during the study period to 43 percent in 2019 from 12 percent in 1990. Alcohol usage rose slightly during the study period.
In addition to the reduction in smoking, other factors driving the decline in coronary heart disease mortality included statins (which lower cholesterol), better diagnostic tests, and more frequent use of those tests.
To achieve this, Ananth’s research team analyzes the largest possible datasets to differentiate risk among various patient subsets.
The new study used anonymized data from the National Center for Health Statistics to track all heart disease fatalities in the targeted age range for the three-decade period. (IB/Newswise)
