Abstract
ObjectiveTo assess the left ventricular systolic function in young strength male athletes by three-dimensional speckle tracking echocardiography (3D-STE).
MethodsA total of 45 young strength male athletes (athlete group) and 30 healthy young men(control group)were enrolled. Traditional echocardiography combined with 3D-STE were applied for all the subjects to obtain heart rate (HR), left ventricular end-diastolic diameter (LVEDD), the thickness of interventricular septum (IVS) and posterior wall thickness (PWT), relative wall thickness (RWT), left ventricular end-diastolic volume (EDV), end-systolic volume (ESV), left ventricular ejection fraction(LVEF), stroke volume (SV), left ventricular mass(LVM), left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global area strain (GAS), global radial strain (GRS).
ResultsThere were a significant increase inLVEDD, IVS, PWT, RWT, EDV, ESV, SV, LVM and significant decrease in HR, GLS, GCS, GAS and GRS in athlete group compared with the control group (P<0.05). However, there was no significant difference in LVEF between two groups (P>0.05).
ConclusionsThere are subclinical changes of left ventricular systolic functionin of young strength male athletes.3D-STE can accurately assess the changes, and provide reliable information for clinical assessment of athletes′ heart function.
