Heart Attack Prevention: The Essential Tests to Get Before Age 50
Moving Beyond Basic Cholesterol
For years, doctors checked LDL (known as "bad cholesterol") to judge heart health. However, many people with normal LDL levels still suffer heart attacks. Modern science has found better, more accurate ways to check your risk.
Important Tests to Ask For
- ApoB (Apolipoprotein B): Instead of measuring the weight of cholesterol, this test counts the actual number of particles that can clog your arteries. It is a much better predictor of heart health.
- Lp(a): A specific, sticky type of cholesterol particle that is hereditary. You only need to test this once in your life to know if you carry it.
- CAC Score (Coronary Calcium Scan): A quick, low-dose CT scan of your heart. It checks for actual calcium buildup in your arteries, giving you a clear picture of your heart's physical state.
