The Claim
In adults with elevated coronary artery calcium (CAC >100 Agatston units), not currently smoking is associated with a 40% lower risk of all-cause mortality and a 42% lower risk of atherosclerotic cardiovascular disease (ASCVD), and delays the onset of these events by 67% and 68%, respectively, suggesting that smoking cessation may contribute to prolonged cardiovascular health even in advanced subclinical disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you’re an adult with early signs of heart artery damage but don’t smoke, you’re much less likely to die or have a heart attack or stroke compared to smokers—even if your heart is already showing damage. Quitting smoking might still help you live longer and healthier, even at this stage.

What the research says
1 studyThe study found that adults with early signs of heart disease who don’t smoke live longer and have fewer heart problems than those who do smoke—even when they already have significant artery plaque. This supports the idea that quitting smoking helps, even at advanced stages.
