Why the study?
Does endurance training induce echocardiographic left ventricular hypertrophy in Chinese athletes?
Does endurance training induce echocardiographic left ventricular hypertrophy in Chinese athletes?
This study provides early evidence that athletic heart syndrome, including left ventricular hypertrophy, occurs in Asian endurance athletes similarly to Caucasian athletes.
Supports athletic heart syndrome in Chinese athletes; hypothesis-generating and should not yet change practice or norms.
Most echocardiographic data on the athletic heart syndrome originate from the United States and Western Europe. There are no published data on echocardiographically documented left ventricular hypertrophy in Asian athletes. We investigated the echocardiographic changes which take place with endurance training by studying eight Hong Kong national cyclists. This study confirms that left ventricular hypertrophy and increased left ventricular end-diastolic dimensions are common findings in Chinese endurance athletes as in their Caucasian counterparts. Calculated left ventricular muscle mass exceeded the 95th percentile in seven of eight subjects.
