For years, the conversation around cholesterol has been simplified to “good” HDL versus “bad” LDL. While this is a helpful starting point, cardiologists are urging people to look deeper into their lipid panel results. A more nuanced understanding is critical, especially in diverse populations where unique risk factors, like ‘atherogenic dyslipidaemia,’ are common.
The standard LDL-C number, which measures the concentration of LDL cholesterol, is important, but it doesn’t tell the whole story. Another crucial factor is the type of LDL particles. Small, dense LDL particles are considered far more dangerous than larger, fluffier ones because they can more easily penetrate the arterial wall and initiate the plaque-building process. Unfortunately, a standard panel doesn’t differentiate between these.
Triglycerides are another key player often overlooked. These are a different type of fat in your blood, and high levels are an independent risk factor for heart disease. Elevated triglycerides, especially when combined with low levels of HDL (the “good” cholesterol that helps remove plaque), create a particularly hazardous environment for your arteries.
This is why the concept of ‘atherogenic dyslipidaemia’—the triad of high triglycerides, low HDL, and high small, dense LDL—is so important. A person could have a borderline LDL reading but be at extremely high risk due to this dangerous combination. This highlights the need for a comprehensive assessment that considers the entire lipid profile, not just one or two numbers.
Talk to your doctor about your complete results. Ask about your triglyceride-to-HDL ratio and other risk markers. Understanding the full story your cholesterol panel is telling is the first step toward a more personalized and effective plan to protect your cardiovascular health.
