Role of Muscular Strength on the Risk of Sudden Cardiac Death in Men.

Abstract

To the Editor: The effect of cardiorespiratory fitness (CRF) on sudden cardiac death (SCD) has been summarized,1 with the conclusion that the risk of SCD decreases by 14% to 22% per 1-metabolic equivalent task increase in CRF.1 Recently, Mayo Clinic Proceedings has not only emphasized articles on CRF2-4 but also articles on resistance exercise and muscular strength (MusS).5-7 However, there is no study of the effect of MusS on SCD, even though MusS was inversely and independently associated with all-cause mortality in healthy men.8 Consequently, this report investigated the effect of MusS as a predictor of SCD, independent of potential risk factors, and explored the combined influence of MusS and CRF on the risk of SCD.
