This study investigated the risk factors for death in patients after they had suffered a heart attack. The study included 11,324 men and women from the GISSI-Prevenzione trial who were followed for four years.

Regarding cholesterol levels, the study found that those with the lowest cholesterol, under 190 mg/dL (4.91 mmol/L), had a 75% increased risk of death compared to those with the highest cholesterol, over 245 mg/dL (6.3 mmol/L).
