BACKGROUND

Athletes have changes that can mimic pathological cardiomyopathy.

METHODS

Echocardiographic study of 50 male, female athletes (MA, FA) and non-athletes (MNA, FNA) age 18 to 30 years. These athletes participate in sports with predominantly endurance component. All participants exhibit no known medical illnesses or symptoms.

RESULTS

MA have thicker wall (IVSd) than MNA. No MA have IVSd > 1.2 cm and no FA have IVSd > 1.0 cm. Left ventricle internal dimension (LVIDd), left ventricle end diastolic volume index (LVEDVi) is bigger in athletes. None have LVIDd > 5.8 cm. Right ventricle fractional area change (FAC) is lower in athletes. (MA vs MNA, p = 0.013, FA vs FNA, p = 0.025). Athletes have higher septal and lateral e' (Septal e'; MA 13.57 ± 2.66 cm/s vs MNA 11.46 ± 2.93 cm/s, p < 0.001, Lateral e'; MA 17.17 ± 3.07 cm/s vs MNA 14.82 ± 3.14 cm/s, p < 0.001), (Septal e'; FA 13.46 ± 2.32 cm/s vs FNA 12.16 ± 2.05 cm/s, p = 0.04, Lateral e'; FA 16.92 ± 2.97 cm/s vs FNA 15.44 ± 2.29 cm/s, p = 0.006).No difference in Global longitudinal (GLS), Right ventricle free wall (RVFWS) and Global circumferential strain (GCS). Left atrial reservoir (LArS) and left atrial booster strain (LAbS) is smaller in athletes. (LArS, MA 44.12 ± 9.55% vs MNA 52.95 ± 11.17%, p < 0.001 LArS, FA 48.07 ± 10.06% vs FNA 53.64 ± 8.99%, p = 0.004), (LAbS, MA 11.59 ± 5.13% vs MNA 17.35 ± 5.27%, p < 0.001 LAbS FA 11.77 ± 4.65% vs FNA 15.30 ± 4.19%, p < 0.001).

CONCLUSION

Malaysian athletes have thicker wall and bigger left ventricle than controls. No athletes have IVSd > 1.2 cm and/or LVIDd > 5.8 cm. There is no difference in GLS, RVFWS and GCS but athletes have smaller LArS and LAbS.

背景

运动员存在一些可模拟病理性心肌病的变化。

方法

对50名年龄在18至30岁的男性和女性运动员（男运动员、女运动员）及非运动员（非男运动员、非女运动员）进行超声心动图研究。这些运动员主要参与耐力项目运动。所有参与者均无已知的疾病或症状。

结果

男运动员的室间隔厚度（IVSd）比非男运动员厚。没有男运动员的IVSd>1.2厘米，也没有女运动员的IVSd>1.0厘米。运动员的左心室内径（LVIDd）、左心室舒张末期容积指数（LVEDVi）更大。没有人的LVIDd>5.8厘米。运动员的右心室面积变化分数（FAC）更低。（男运动员与非男运动员相比，p = 0.013；女运动员与非女运动员相比，p = 0.025）。运动员的室间隔和侧壁e'更高（室间隔e'；男运动员13.57±2.66厘米/秒，非男运动员11.46±2.93厘米/秒，p<0.001；侧壁e'；男运动员17.17±3.07厘米/秒，非男运动员14.82±3.14厘米/秒，p<0.001），（室间隔e'；女运动员13.46±2.32厘米/秒，非女运动员12.16±2.05厘米/秒，p = 0.04；侧壁e'；女运动员16.92±2.97厘米/秒，非女运动员15.44±2.29厘米/秒，p = 0.006）。整体纵向应变（GLS）、右心室游离壁（RVFWS）和整体圆周应变（GCS）无差异。运动员的左心房储器应变（LArS）和左心房增强应变（LAbS）更小。（LArS，男运动员44.12±9.55%，非男运动员52.95±11.17%，p<0.001；LArS，女运动员48.07±10.06%，非女运动员53.64±8.99%，p = 0.004），（LAbS，男运动员11.59±5.13%，非男运动员17.35±5.27%，p<0.001；LAbS，女运动员11.77±4.65%，非女运动员15.30±4.19%，p<0.001）。
