Heart attack deaths plummet 90% in 50 years – but three other conditions are surging, study warns

A new study shows heart attack In the United States, deaths have dropped almost 90% over 50 years – but others heart disease are increasing.

Posted Wednesday in the Journal of the American Heart Association,, researchers of Stanford The school of university medicine has analyzed the age -adjusted cardiac mortality rates in adults aged 25 and more than 1970 to 2022.

The researchers discovered that overall heart disease Deaths dropped 66% over 50 years, mainly due to a drop of 89% heart attack death.

In 1970, heart attack caused more than half of the deaths by heart disease, but by 2022, they represented less than a third.

“This evolution in the past 50 years reflects incredible successes in the way heart attacks and other types of ischemic heart disease is managed,” said Sara King, MD, the first author of the study and second year resident of internal medicine at the Stanford School of Medicine in California, in a Press release.

“There have been great progress to help people survive the initial acute hearts that were once considered a death sentence,” she added.

Progress as more RCR of passing, better awareness of early symptoms of the heart attack, improved treatments and unmoved laws have contributed to reducing the death of the heart attack.

However, experts warn that, while more and more people survive heart attacks, other forms of heart disease are now increasing.

Deaths by arrhythmia, when the heart beats too quickly, too slow or irregularly increased, increased by 450%, while death -in -law increased by 146%.

The deaths of hypertensive heart disease increased by 106%, driven by a long -term high blood pressure. The researchers connect these increasing causes of death to obesity, diabetes and high blood pressure in the United States

In the United States, obesity increased from 15% in the 1970s to 40% by 2022. Almost half of adults have now Type 2 diabetesAnd high blood pressure rates increased from 30% in 1978 to almost 50% in 2022.

“The emphasis must now be to help people age with strong and healthy hearts by preventing events, and prevention can start from childhood,” said the main author Latha Palaniappan, MD, Dean Associate for Research and Professor at the Stanford University School of Medicine.
