reports that in 1988 there were 42,940 deaths in the United States for which congestive heart failure (CHF) was designated as the underlying cause of death (Thom, 1991~.

Kottke and colleagues projected that there would be 16,500 potential candidates for cardiac replacement nationally each year. This estimate was based on assumptions that the 95,000 residents of Olmsted County were representative of all Americans, and that the population of the United States was 225 million at the time of the study, calendar years 1979 through 1983.

If it is assumed that the Olmsted County deaths were indeed due to a broader range of heart problems than merely heart failure, then the 14 percent figure could be applied to NCHS mortality statistics for coronary heart disease (CHD) , cardiomyopathy, and heart failure the most frequent sources of ventricular dysfunction.

Whereas these are the most precise figures obtainable, they must be viewed with much caution since they were calculated using percentages of sudden death and comorbidity derived from Olmsted County data. It is known that Olmsted County residents have better access to medical care, are more predominantly white (99 percent)

The impact of primary prevention and medical care on mortality trends, however, is extremely difficult to determine. The increase in the target population for long-term MCSS reflects the anticipated growth of the general population during the next 30 years, and in particular the movement of the "baby boom" generation born in the 1940s and 1950s into the age range of increased risk of heart disease.

Congestive Heart Failure The best available estimate of the prevalence of CHF in the United States is 3,037,665 (Thom, 1991~. This figure was obtained by applying the rates observed in two community studies conducted in 1962 by Gibson and colleagues (1966)

Coronary Heart Disease National Hospital Discharge Survey data indicate that there were over 2 million discharges for CHD in 1988. Of these, 716,000 were for acute MI, 411,000 were for atherosclerotic heart disease, and 921,000 were for other ischemic heart diseases.

Potential differences in diagnostic customs and classification procedures, however, make international comparisons, and thus the validity of such calculations, highly speculative. Additionally, calculations using percentages of sudden death and comorbidity derived from Olmsted County where socioeconomic status is higher and access to medical care is better—would result in spuriously low international estimates.
