High fasting serum triglyceride levels (specifically 1.6–2.5 mmol/L) are a strong, independent risk factor for ischemic heart disease (IHD), even in individuals with high HDL cholesterol levels.

If you are a middle-aged or older man, your fasting triglyceride levels matter for your heart disease risk, even if your HDL (good cholesterol) is high. A level between 1.6 and 2.5 mmol/L is associated with a significantly higher risk of heart events. This suggests that managing triglycerides (often through diet, specifically reducing refined carbohydrates and alcohol) is crucial, regardless of your HDL status.

GoodSupportsHIGH confidence
In middle-aged and elderly white men, a high level of fasting triglycerides is a strong risk factor of IHD independent of other major risk factors, including HDL cholesterol.

Why this rating

Large prospective cohort study (n=2906) with 8-year follow-up, rigorous adjustment for confounders, but observational design limits causal inference.
