What should your target LDL level be?
Heart disease is the leading cause of death and disability in the United States and LDL is the cause. Managing LDL is possibly the single most important factor in avoiding death or disability from heart disease.
The Role of LDL Cholesterol in Heart Disease
LDL initiates the process of plaque buildup in your arteries by getting stuck in the arterial wall. This eventually leads to a buildup called a fatty streak which can result in heart attacks, stroke or other issues likely to kill or disable you. Understanding and managing LDL is the first step in preventing these conditions.
What Should Your LDL Target Level Be?
There is no one size fits all target LDL. The level that is safe depends on how long you plan on living, your risk factors (like high blood pressure) and how much LDL exposure you've already had. Current research indicates that maintaining lifelong LDL under 85 mg/dl [1] would allow most people to live to 100 without heart disease.
The damage LDL creates occurs over time, so you can multiply the amount of LDL by the numbers of years you live to understand cumulative damage (measured in mg/dl Years). There is no one level of cumulative exposure when heart disease begins, but as a loose rule of thumb when cumulative LDL exposure reaches ~7,500 mg/dl Years we start to experience elevated risk of heart disease. This is of course an oversimplification, but crudely to estimate a "safe-ish" average cholesterol level through life you could use. [2]
Safe LDL = 7500 / (How Long I Plan To Live)
High LDL History
Since cholesterol damage is cumulative, and initiated by LDL, low LDL early in life is important. Even if your LDL has been high, it seems like significant reductions in LDL can still decrease your risk, but as with everything to do with cholesterol, acting earlier is better.
If you've had LDL > 100 mg/dl and you're over 40, it's likely you've already developed significant plaque. [3] There is evidence these plaques can be shrunk by reducing LDL levels to below 60 mg/dl. [4] For later stage disease you may even consider significantly lower targets with trials going as low as below 20 mg/dl.
The Critical Role of Early LDL Management
Starting LDL management as early as your 20s is crucial for preventing heart disease. The initial stages of heart are characterized by LDL particles stuck in artery walls. The process cannot begin until after this has happened, but once it has happened it's irreversible. Delaying the beginning of heart disease into your 30s and even 40s would greatly improve your chances of living your whole life free of heart disease.
