Most of us know the routine: get your cholesterol checked, aim for good HDL and low LDL. But when it comes to predicting heart disease, are we overlooking more telling tests? According to leading cardiology experts, two key blood markers – ApoB and Lipoprotein(a) – can offer critical insight into your heart health risk. Yet many people have never even heard of them. Here’s why these tests matter and what they reveal about your heart.   Apolipoprotein B (ApoB): Your “Bad Cholesterol” Particle Count What it is:   ApoB is a protein found on all the particles that carry “bad” cholesterol in your blood – including LDL, VLDL, and others. Essentially, each ApoB corresponds to one cholesterol-carrying particle. The ApoB test measures the total number of these atherogenic particles circulating in your bloodstream. This is important because the number of cholesterol particles can be more predictive of heart disease risk than the standard LDL cholesterol concentration alone....
