Women with high HDL cholesterol levels of greater than 90 mg/dl were 50% times more likely to die from other causes other than dying from cancer or cardiovascular disease during an average follow-up of 4.9 years than women with HDL levels of 61-70 mg/dl according to a 2016 study from Canada.
(3.0 per 1,000 women with HDL levels greater than 90 mg/dl died from cardiovascular disease versus 2.0 women with HDL levels of 61-70 mg/dl. 3.0 divided by 2.0 equals 1.5.)
The study found that HDL levels that were either too high (>90 mg/dl) or too low (≤30 mg/dl) were associated with an increased risk of death when compared to women with more moderate HDL levels (41-80 mg/dl).
HDL is not a cardiovascular-specific risk factor
HDL is not a target for intervention
Because people with high HDL levels were more likely to die from cancer and non-cardiovascular causes, the authors of the study concluded that:
“These findings suggested that HDL [cholesterol] level is unlikely to represent a cardiovascular-specific risk factor or a target for intervention given similarities in its associations with non cardiovascular outcomes,” the authors of the study concluded.
Subjects
Subjects: 631,762 people
The study followed 631,762 people from the CANHEART (Cardiovascular Health in Ambulatory Care Research Team) dataset, which was created by linking together 17 different individual-level data sources.
On average, people were 57-years-old and had an HDL level of 55 mg/dl.
