Does habitual vigorous exercise training mitigate the transiently increased risk of sudden cardiac death due to myocardial infarction associated with vigorous exertion in men?
Habitual vigorous exercise training mitigates the transiently increased risk of sudden cardiac death triggered by acute vigorous exertion.
Among Swedish men who experienced SCD caused by MI, vigorous exertion was associated with a transiently increased risk, which was mitigated by higher levels of habitual vigorous exercise training.
Vikström et al. (Wed,) studied this question.
