6 Hidden Heart Disease Markers Cardiologist Say Are More Important Than Total Cholesterol

Many studies have found that "normal" cholesterol levels are often linked to heart disease, whereas people with higher cholesterol levels can remain heart healthy. Check out why these six heart disease markers are crucial beyond total cholesterol.

Total Cholesterol

Many people assume total cholesterol as the primary measurement for cardiovascular health monitoring since the 1950s. Yet cardiologists explain that this one measurement fails to provide complete health information. Multiple studies have shown that people with "normal" cholesterol levels can develop heart disease, while people with higher cholesterol levels can maintain heart health. These findings demonstrate that multiple hidden testing indicators provide better assessment methods for determining cardiovascular disease risk. Here are six hidden heart disease markers cardiologists say are more important:

2 / 6

Apolipoprotein B (ApoB)

ApoB measures the complete count of dangerous lipoprotein particles which include both LDL and very low-density lipoproteins. The increase in particle quantity results in a raised level of ApoB, which indicates a higher plaque-building capacity, thus raising the risk of cardiovascular disease.

3 / 6

Lipoprotein

The lipoprotein(a) blood test looks to detect lp(a) as a genetic risk factor. This means that elevated lp(a) levels establish a higher risk for heart attacks and strokes because they activate plaque buildup through clotting processes which occur even when individuals possess healthy cholesterol levels. Science Direct states, “Generally, Lp(a) levels remain stable over time; thus, most individuals need only undergo Lp(a) testing through a non-fasting blood draw once in their lifetime, unless elevated Lp(a) is identified.”

4 / 6

LDL Particle Number (LDL-P)

The different types of LDL cholesterol which exist in the body exhibit distinct characteristics. Standard testing methods assess LDL cholesterol content, but LDL-P measures the actual number of lipid particles which transport LDL cholesterol. The risk of cholesterol entering artery walls for plaque formation increases when the particle count reaches a high level, despite normal LDL test results.

5 / 6

Triglyceride-to-HDL Ratio

Cardiologists often study triglycerides and HDL together because they consider these two measurements to be more informative than evaluating each measurement separately. High triglyceride-to-HDL ratio people develop insulin resistance and metabolic syndrome, which increases their risk for cardiovascular disease development.

6 / 6

High-Sensitivity C-Reactive Protein (hs-CRP)

Cholesterol functions as one element of heart disease, which develops through body inflammation. The hs-CRP test measures low-grade inflammation.
