Discuss the relationship between changes in lifestyle and decline in cardiovascular disease in the United States and other industrialized nations.​

A. Cardiovascular disease (CVD) is the leading cause of death in the United States and other industrialized nations, and 34% of deaths are due to CVD.
B. Deaths from CVD have declined from their high in the mid-1960s, and both lifestyle changes and medical care have contributed to the decline.
C. This decline has occurred in some industrialized countries but not in others.
1. This decline has occurred in the United States, Finland, and other high-income Western countries.
2. In countries of the former Soviet Union, rates of CVD had risen dramatically, especially among middle-aged men, but began dropping in many of these countries during the first decade of the 21st century.
D. About 44% of the decline in CVD is related to changes in lifestyle, and about 47% is due to improvements in medical care.
1. The rate of heart attacks has decreased, and this decrease seems to be related to changes in lifestyle.
2. Some decline in CVD mortality is due to improved medical procedures: the survival rate for those who have had heart attacks has increased.
