Abstract

Background: Right atrial longitudinal strain (RALS) is a useful parameter to define right atrial (RA) subclinical dysfunction prior to changes in RA dimension and volume. We sought to establish normal values for RALS in a sub-Saharan African population.

Methods: This was a retrospective, cross-sectional study from 2017 to 2019 of 100 normal individuals. All echocardiographic measurements were done as per the standard guidelines.

Results: Mean RALS was 32.7 ± 10.5%. The mean RA volume indexed to body surface area was 19.5 ± 5.7 ml/m². There was a negative correlation between RALS and age but it was not statistically significant (r = -0.15, p = 0.129). Males had a tendency towards higher RA volume indexed and RALS measurements compared to females (20.8 ± 6.3 and 18.7 ± 5.2 ml/m², p = 0.07; 34.6 ± 9.6 and 31.4 ± 10.9%, p = 0.141, respectively). Body mass index was an independent predictor of RALS (r = -0.43, p = 0.003).

Conclusion: We have provided normative data for RALS in an African population. This study provides a platform for future larger studies on RALS.

非洲正常成年人口右心房应变随年龄的变化。

背景：右心房纵向应变（RALS）是在右心房尺寸和容积发生变化之前确定右心房亚临床功能障碍的有用参数。我们试图在撒哈拉以南非洲人群中确定 RALS 的正常值：这是一项从 2017 年到 2019 年的回顾性横断面研究，研究对象为 100 名正常人。所有超声心动图测量均按照标准指南进行：平均RALS为32.7±10.5%。RA体积与体表面积的平均指数为19.5 ± 5.7 ml/m2。RALS与年龄呈负相关，但无统计学意义（r = -0.15，p = 0.129）。与女性相比，男性的 RA 容量指数和 RALS 测量值更高一些（分别为 20.8 ± 6.3 和 18.7 ± 5.2 毫升/平方米，p = 0.07；34.6 ± 9.6 和 31.4 ± 10.9%，p = 0.141）。体重指数是 RALS 的独立预测因子（r = -0.43，p = 0.003）：我们提供了非洲人群 RALS 的标准数据。本研究为今后更大规模的 RALS 研究提供了一个平台。
