Why the study?
Cardiorespiratory optimal point during exercise may be an independent risk factor for cardiovascular disease outcomes, but its relationship with sudden cardiac death risk had not been investigated.
Is cardiorespiratory optimal point (COP) during exercise testing associated with the risk of sudden cardiac death in men?
Population

Comparison

May support COP in SCD risk models for men; hypothesis-generating pending prospective validation.
Is cardiorespiratory optimal point (COP) during exercise testing associated with the risk of sudden cardiac death in men?
Cardiorespiratory optimal point during exercise testing is an independent predictor of long-term sudden cardiac death risk in men.
Laukkanen et al. (2021) studied this question.
