Epidemiologists have found that approximately half the recent fall in coronary heart disease deaths in the US is due to positive life style changes and a further half to medical therapies.
The team found that a decrease in smoking, cholesterol, blood pressure and physical inactivity contributed to the fall in deaths from coronary heart disease, yet this decrease could have been substantially more had it not been for the increases in obesity and diabetes cases.
Coronary heart disease (CHD) death rates in the US almost halved between 1980 and 2000. To understand how this fall occurred scientists combined information on medical treatments with national changes in the levels of major risk factors, such as smoking and high cholesterol. The UK has seen similar falls in heart disease, but this fall is mainly attributed to healthier diets rather than medication.
From 1980 to 2000, the US death rates for CHD fell from 543 to 267 per 100,000 population among men and from 263 to 134 per 100,000 population among women. Overall there were 341, 745 fewer CHD deaths in 2000 than in 1980.
The team found that this decrease was attributed to reductions in risk factors such as total cholesterol, systolic blood pressure, smoking and physical inactivity. However, they found that this reduction could have been 15% more had it not been for an increase in obesity and diabetes. Approximately half the fall in CHD deaths was also attributed to medical treatments, including medications for heart failure and emergency treatments for heart attacks and angina.
