deadliest form of heart disease

Heart attacks are no longer the leading cause of death in the US

Deaths from heart attacks have plummeted in the US over the past 50
years, whereas deaths from chronic heart conditions have skyrocketed,
probably due to people living longer.

They found that in 2022, heart disease accounted for 24 per cent of
all deaths in the US, down from 41 per cent in 1970. The decline is
largely thanks to an almost 90 per cent decrease in heart attack
deaths, which were once the deadliest form of heart disease.

"Incredible progress has been made to reduce deaths from heart attacks
over the last 50 years," says King. This includes new therapies such
as heart stents, coronary artery bypass surgery and
cholesterol-lowering medications. Public health measures, such as
bystander CPR training and efforts to lower smoking rates, have also
probably helped, says King.

Even so, heart disease remains the country's top killer, mainly
because deaths from other types of heart disease - mostly chronic
conditions - have increased 81 per cent over the same period. For
instance, fatalities from heart failure, arrhythmia and hypertensive
heart disease have risen 146 per cent, 106 per cent and 450 per cent,
respectively.
