Overview
Athlete's heart is a term that refers to concentric and symmetric hypertrophy of the left ventricle that occurs in some athletes. It is important to distinguish Athlete's heart, which is not a true cardiomyopathy from hypertrophic obstructive cardiomyopathy (HOCM), which is a true cardiomyopathy and places the athlete at risk of sudden death.
Traditional Criteria for Distinguishing Athlete's Heart from HOCM
Several criteria can be used to distinguish these two entities:
The degree of left ventricular wall thickness
- In athlete's heart the LVH is symmetric and less than or = to 12 mm
- Rarely the LV thickness can be 14-16 mm and this makes it difficult to distinguish from HOCM. Athletes who engage in strength training may develop this pattern, ahtletes who engage in endurance training do not.
- If the degree of thickening is out of proportion to the type and intensity of exercise, this suggests HOCM
The pattern of left ventricular wall thickness
- Athleste's heart is symmetric
- HOCM is more often asymmetric, but may in some cases be symmetric
The left ventricular cavity size
- HOCM has smaller LV cavitary dimensions
Sophisticated Criteria and Testing to Distinguish Athlete's Heart from HOCM
- Doppler mitral valve inflow patterns are diagnostic of HOCM
- Tissue doppler echocardiography
- Electrocardiogram: HOCM is favored if there are prominent q waves, large increases in voltages, and deep T wave inversions
- The presence of an LV outflow tract gradient favors the diagnosis of HOCM
- A speckled pattern on MRI favors the diagnosis of HOCM
