Cardiovascular Quiz
Quiz
Which lipid metric best predicts cardiovascular events?
Pick the single strongest single-lab-value predictor.
ApoB directly counts atherogenic particles — one ApoB per particle. LDL-C measures how much cholesterol is in those particles, which is useful but noisier. Total cholesterol mixes atherogenic + protective particles. HDL-C doesn't predict events causally.
Quiz
How much of the population has elevated Lp(a)?
The most common genetically-determined CVD risk factor.
About 20% of the population has clinically elevated Lp(a). Most don't know because it's rarely measured. It's ~90% heritable and stable for life — a single test, lifelong answer.
Quiz
What does CAC scoring measure?
Pick the correct description.
CAC — Coronary Artery Calcium — is a non-contrast CT scan that quantifies calcified plaque in the coronary arteries. Score goes from 0 (pristine) into the thousands. Strongest single test for predicting future cardiac events.
Quiz
Which lifestyle lever has the largest effect on CVD mortality?
From the evidence base covered in this unit.
Regular aerobic exercise reduces CVD mortality by ~30% — the largest single lifestyle lever with published dose-response data. Sleep and diet each contribute ~20–30% separately. Stacking all three matches moderate-dose statin therapy in effect size.
