本探索性研究的目的是明确夏威夷和太平洋岛民(NH&PI)橄榄球联盟(RFL)运动员的运动员心脏(AH)表型。具体地说，(1)描述NH&PI RFL球员和匹配的RFL高加索人(CC)的左、右室结构和功能的常规超声心动图指标；(2)揭示这些人群的左、右室机制。种族是影响AH表型表达的一个重要因素。目前还没有数据描述NH和PI运动员的心脏表型。采用常规超声心动图和心肌斑点追踪法对21名优秀男性NH&PIRFL运动员进行评估，以评估整体纵向应变(ε)和最大应变率(SR)，以及基础、中部和整体径向和周向ε和SR。还评估了基底部和根尖的旋转和扭转。结果与年龄匹配的高加索人(CC；n = 21)进行比较。NH和PI组的LV质量[42 ± 9比37 ± 4µg/(m2.7)]、平均室壁厚度(MWT：9.5 ± 0.7和8.7 ± 0.4 mm)、相对室壁厚度(RWT：0.35 ± 0.0 4和0.31 ± 0.0 3)和右室壁厚度(5 ± 1和4 ± 1 mm，均p <； 0.0 5)均大于CC组。两组间左、右室腔大小及标准左、右室收缩、舒张期功能指标相似。NH和PI表现为LV中周向峰值ε和舒张期早期SR降低，以及整体放射状ε降低。NH和PI运动员收缩25%~35%时基础旋转减少，收缩25%~40%和60%~100%时心尖旋转减少，收缩85%~95%时扭转减少。两组右室壁力学指标差异无统计学意义。与高加索对照组相比，NH和PI橄榄球运动员具有更大的LV质量、MWT和RWT，并伴随着圆周和扭转力学的减少。这一数据促进了对NH和PI运动员的进一步研究。
The aim of this exploratory study was to define the Athletes Heart (AH) phenotype in Native Hawaiian & Pacific Islander (NH&PI) Rugby Football League (RFL) athletes. Specifically, (1) to describe conventional echocardiographic indices of left ventricle (LV) and right ventricle (RV) structure and function in NH&PI RFL players and matched RFL Caucasian controls (CC) and (2) to demonstrate LV and RV mechanics in these populations. Ethnicity is a contributory factor to the phenotypical expression of the AH. There are no data describing the cardiac phenotype in NH&PI athletes. Twenty-one male elite NH&PI RFL athletes were evaluated using conventional echocardiography and myocardial speckle tracking, allowing the assessment of global longitudinal strain (ε) and strain rate (SR); and basal, mid and global radial and circumferential ε and SR. Basal and apical rotation and twist were also assessed. Results were compared with age-matched Caucasian counterparts (CC; n = 21). LV mass [42 ± 9 versus 37 ± 4 g/(m2.7)], mean LV wall thickness (MWT: 9.5 ± 0.7 and 8.7 ± 0.4 mm), relative wall thickness (RWT: 0.35 ± 0.04 and 0.31 ± 0.03) and RV wall thickness (5 ± 1 and 4 ± 1 mm, all p < 0.05) were greater in NH&PI compared with CC. LV and RV cavity dimensions and standard indices of LV and RV systolic and diastolic function were similar between groups. NH&PI demonstrated reduced peak LV mid circumferential ε and early diastolic SR, as well as reduced global radial ε. There was reduced basal rotation at 25–35% systole, reduced apical rotation at 25–40% and 60–100% systole and reduced twist at 85–95% systole in NH&PI athletes. There were no differences between the two groups in RV wall mechanics. When compared to Caucasian controls, NH&PI rugby players have a greater LV mass, MWT and RWT with concomitant reductions in circumferential and twist mechanics. This data acts to prompt further research in NH&PI athletes.
