This study investigated the association of cholesterol levels with death rates in patients hospitalised with heart failure. The study included 2,428 patients who were followed for 2.9 years.

The study found that those with low levels of low density liporotein (LDL) cholesterol, less than 71 mg/dL (1.8 mmol/L), had a 68% increased death rate compared to those with high levels of low density liporotein (LDL) cholesterol, more than 130 mg/dL (3.3 mmol/L).

This study evaluated the effect of cholesterol levels on patients hospitalized due to heart failure. The study included 2,797 heart failure patients.

The study found that the patients with the lowest cholesterol levels, had a 57% increased risk of death and readmission to hospital due to heart failure compared to the patients with the highest cholesterol levels.
