“…63 Although initially considered to carry a very high mortality rate, recent data suggest that survival of commotio cordis occurs in up to 58% of cases. 63,64 Improved survival may reflect early recognition of the event, activation of emergency medical services, effective early bystander cardiopulmonary resuscitation (CPR), and early defibrillation.…”

“…Survival of these events has been by faster response times and availability of an on-site automated external defibrillator. There remains a greater risk of mortality when commotio cordis occurs during noncompetitive rather than competitive sports, or in African Americans [29,30]. A condition for fatality is that the chest blow occurs during a vulnerable window preceding the ECG T wave [31].…”

Cardiac mechanical contraction is triggered by electrical activation via an intracellular calcium-dependent process known as excitation-contraction coupling. Dysregulation of cardiac myocyte intracellular calcium handling is a common feature of heart failure. At the organ scale, electrical dyssynchrony leads to mechanical alterations and exacerbates pump dysfunction in heart failure. A reverse coupling between cardiac mechanics and electrophysiology is also well established. It is commonly referred as cardiac mechanoelectric feedback and thought to be an important contributor to the increased risk of arrhythmia during pathological conditions that alter regional cardiac wall mechanics, including heart failure. At the cellular scale, most investigations of myocyte mechanoelectric feedback have focused on the roles of stretch-activated ion channels, though mechanisms that are independent of ionic currents have also been described. Here we review excitation-contraction coupling and mechanoelectric feedback at the cellular and organ scales, and we identify the need for new multicellular tissue-scale model systems and experiments that can help us to obtain a better understanding of how interactions between electrophysiological and mechanical processes at the cell scale affect ventricular electromechanical interactions at the organ scale in the normal and diseased heart.

“…There is a significant male predominance, with 95% of cases occurring in males between the age of 11 and 20 years. 93,94 Investigating the types of projectiles may reveal the reason for the sex discrepancy. In the athletic environment, 81% of commotio cordis is caused by a projectile and the majority caused by equipment, as opposed to a collision with another player, and that 61% of the time, the culprit was a baseball.…”

Gender- and Sex-specific Sports-related Injury Research in Emergency Medicine: A Consensus on Future Research Direction and Focused Application

Title IX, the commercialization of sports, the social change in sports participation, and the response to the obesity epidemic have contributed to the rapid proliferation of participation in both competitive organized sports and nontraditional athletic events. As a consequence, emergency physicians are regularly involved in the acute diagnosis, management, disposition, and counseling of a broad range of sports-related pathology. Three important and highly publicized mechanisms of injury in sports relevant to emergency medicine (EM) include concussion, heat illness, and sudden cardiac death. In conjunction with the 2014 Academic Emergency Medicine consensus conference "Gender-specific Research in Emergency Care: Investigate, Understand, and Translate How Gender Affects Patient Outcomes," a consensus group consisting of experts in EM, emergency neurology, sports medicine, and public health convened to deliberate and develop research questions that could ultimately advance the field of sports medicine and allow for meaningful application in the emergency department (ED) clinical setting. Sex differences in injury risk, diagnosis, ED treatment, and counseling are identified in each of these themes. This article presents the consensus-based priority research agenda.
