Echocardiographic analysis identified an overlap zone between physiological and pathological hypertrophy, where a diastolic diameter under 45 mm and abnormal mitral flow indicated hypertrophic cardiomyopathy.

Can clinical and echocardiographic variables distinguish physiological hypertrophy in athletes from hypertrophic cardiomyopathy?
Patient history, ECG anomalies, septal thickness, diastolic diameter < 45 mm, and response to deconditioning are key variables in distinguishing athlete's heart from hypertrophic cardiomyopathy in borderline cases.
Physiological left ventricular hypertrophy is the result of the left ventricle having to function harder due to intense physical exercise. After exercise is stopped, this modest and reversible hypertrophy persists. Studying these structural alterations is now feasible because to cardiac echodoppler. Distinguishing this adaptive hypertrophy from the pathogenic hypertrophic cardiomyopathy might be challenging at times. We examined 212 athletes who competed and a group of hypertrophic cardiomyopathy patients who had asymmetric septal hypertrophy that was confirmed. The findings demonstrated that there is a boundary between pathological and normal hypertrophy. This zone contained four athletes, one of whom had hypertrophic cardiomyopathy. Numerous variables led to the diagnosis, including the patient's history, electrical anomalies, septal thickness, and a diastolic diameter of less than 45 mm. Deconditioning further supported the diagnosis.
Abdelbaki et al. (Wed,) conducted a observational in Sportsman's Heart and Hypertrophic Cardiomyopathy (n=240). Intense physical exercise (Athlete status) vs. Hypertrophic cardiomyopathy was evaluated on Echocardiographic structural alterations (diastolic diameter, septal thickness). Echocardiographic analysis identified an overlap zone between physiological and pathological hypertrophy, where a diastolic diameter under 45 mm and abnormal mitral flow indicated hypertrophic cardiomyopathy.
