Sport Cardiology (2) Flashcards
Why is left ventricular hypertrophy not bad in athletes?
It is reversible
Why does left ventricular hypertrophy occur in athletes?
Permits enhanced filling and increases CO maintained at high HR
What are some normal findings seen in athletes?
Bradycardia
Increased VO2 max
Sinus arrhythmia
What is syncope in exercise?
Common but concerning (most cases are benign)
What types of syncope occur with exercise?
Post exercise syncope
Syncope during exercise (more concerning)
What can dehydration reduce?
SV and CO (especially in the heat)
What may be triggered if dehydration is coupled with heat illness?
Arrhythmias
What is the leading cause of non traumatic death in athletes?
Sudden cardiac death
Are athletes at a greater risk for sudden cardiac death when compared to general population?
No
What is the most common cause of sudden cardiac death in adults?
Undiagnosed CAD (plaque rupture)
What is the most common mechanism of death with sudden cardiac death?
Ventricular tachyarrhythmia
What is hypertrophic cardiomyopathy?
Persistent hypertrophy despite detraining (genetics)
What is often heard in hypertrophic cardiomyopathy?
Persistent S2 splitting
What are the most common coronary anomalies?
Left coronary artery origins in the right sinus of Valsalva and right coronary artery origins in the left sinus of Valsalva
What is myocardial bridge?
Epicardial coronary artery is tunneled within the myocardium (systolic compression of tunneled segment)
