Cardiac adaptation in athletes of black ethnicity: differentiating pathology from physiology.
Cardiac adaptation to intense physical exercise is determined by factors including age, gender, body size, sporting discipline and ethnicity. Differentiating physiology from pathological conditions such as hypertrophic cardiomyopathy (HCM) is challenging, but relevant, as HCM remains the commonest cause of sudden death in young athletes. ⋯ Such changes highlight the overlap between 'athlete's heart' and morphologically mild HCM with potential for false-positive diagnoses and disqualification from competitive sport. The focus of this article is to provide practical considerations in differentiating physiological adaptation to exercise from cardiac pathology in athletes of black ethnicity.

The outcome for patients after an out-of-hospital cardiac arrest (OHCA) has been poor over many decades and single interventions have mostly resulted in disappointing results. More recently, some regions have observed better outcomes after redesigning their cardiac arrest pathways. ⋯ OHCA treatment requires a multidisciplinary approach, comparable to trauma care; the development of cardiac arrest pathways and cardiac arrest centres may dramatically improve patient care and outcomes. Besides emergency medicine physicians, intensivists and neurologists, cardiologists are playing an increasingly crucial role in the post-resuscitation management, especially by optimising cardiac output and undertaking urgent coronary angiography/intervention.
