Left Ventricular Non-Compaction in Athletes: To Play or Not to Play

摘要: Isolated left ventricular non-compaction (LVNC) has usually been viewed as a rare cardiomyopathy in athletes. However, with advances diagnostic imaging techniques and increased use of pre-participation screening electrocardiograms (ECGs), apparent LVNC is being recognized an increasing number Given the lack true gold standard for diagnosis, significant debate continues regarding optimal criteria. There are data to support possibility over-diagnosing this athletic population due physiologic adaptation extreme preload afterload characteristic intense participation. This appears be particularly African-American or African-Caribbean The most common presenting symptom athlete exertional syncope. Evaluation at-risk will typically include complete history, attention cardiac symptoms, family history premature cardiovascular disease sudden death (SCD), physical examination, 12-lead ECG, two-dimensional echocardiography, and, some cases, magnetic resonance gadolinium contrast. In addition, stress 24- 48-h Holter monitoring, 30-day event monitoring arrhythmias may necessary fully evaluate athlete's risk. Adverse outcomes dysfunction, arrhythmias, syncope, SCD, thromboembolism. Asymptomatic athletes hypertrabeculation ventricle but normal function likely do not require restrictions on activity. Symptomatic individuals who meet criteria LVNC, especially those abnormal exercise-induced symptoms should prohibited from participating vigorous sports activities.
