This study sought to determine the relationship of cholesterol levels to long-term survival rates in elderly survivors of a heart attack. The study analysed the death rates of 4,923 heart attack patients aged 65 and older for six years.

The study found:
(a) After one year those with the lowest cholesterol levels (less than 160 mg/dL or 4.1 mmol/l) had 5% more deaths than those with the highest cholesterol (above 240 mg/dL or 6.2 mmol/l).
(b) After six years those with the lowest cholesterol levels (less than 160 mg/dL or 4.1 mmol/l) had 7.6% more deaths than those with the highest cholesterol (above 240 mg/dL or 6.2 mmol/l).

The results of the study show that heart attack survivors live longer if they have high cholesterol.
