Abstract

Objective

This study aimed to assess alterations in right ventricular (RV) function following percutaneous coronary intervention (PCI) in patients with chronic coronary syndromes utilizing three-dimensional speckle tracking echocardiography (3D-STE).

Methods

A prospective study was conducted involving 136 patients diagnosed with chronic coronary syndromes undergoing PCI, constituting the study group, alongside 110 age- and gender-matched healthy volunteers serving as the control group. Echocardiographic evaluations, including both conventional and three-dimensional assessments, were performed on all study participants at 1-week, 6, and 12 months post-PCI. Parameters such as tricuspid annular plane systolic excursion (TAPSE) were derived from conventional echocardiography, while tricuspid lateral annular systolic velocity (S') was measured via tissue Doppler imaging. 3D-STE was utilized to quantify metrics including right ventricular fractional area change (RVFAC), right ventricular free wall longitudinal strain (RVFWLS), right ventricular global longitudinal strain (RVGLS), right ventricular stroke volume (RVSV), and right ventricular ejection fraction (RVEF).

Results

TAPSE, S', RVFAC, RVFWLS, RVGLS, RVSV, and RVEF exhibited significant increases from 1-week to 6 months post-PCI (p < 0.05). However, from 6 to 12 months post-PCI, RVFAC, RVGLS, RVSV, and RVEF demonstrated no notable changes (p > 0.05). Meanwhile, TAPSE, S', and RVFWLS sustained significant elevations: TAPSE (19.63 ± 3.253% to 22.603 ± 2.885%, p < 0.001); S' (10.57 ± 2.643 to 12.61 ± 2.189 cm/s, p < 0.001); RVFWLS (18.64 ± 2.745% to 19.926 ± 3.291%, p = 0.002). At 12 months post-PCI, S', RVFAC, RVGLS, RVSV, and RVEF remained lower than those of the healthy control group, but the differences were not statistically significant (p > 0.05). However, RVFWLS was significantly lower compared to the healthy control group (19.926 ± 3.291% vs. 22.10 ± 1.994%, p < 0.001).

Conclusion

Following PCI, right ventricular systolic function in patients with chronic coronary syndromes improves significantly over time. However, even at the 12-month post-PCI mark, RVFWLS remains lower than that of the control group. Notably, 3D-STE emerges as a noninvasive method for quantifying right ventricular systolic function post-PCI in chronic coronary syndrome patients.

经皮冠状动脉介入治疗后慢性冠状动脉综合征患者右心室功能的三维斑点追踪超声心动图评估

研究目的本研究旨在利用三维斑点追踪超声心动图（3D-STE）评估慢性冠状动脉综合征患者经皮冠状动脉介入治疗（PCI）后右心室（RV）功能的变化：研究人员进行了一项前瞻性研究，136 名确诊为慢性冠状动脉综合征的患者接受了经皮冠状动脉介入治疗（PCI），构成研究组，110 名年龄和性别匹配的健康志愿者作为对照组。所有研究对象均在PCI术后1周、6个月和12个月时接受了超声心动图评估，包括常规和三维评估。三尖瓣瓣环平面收缩偏移（TAPSE）等参数来自常规超声心动图，而三尖瓣侧瓣环收缩速度（S'）则是通过组织多普勒成像测量的。三维超声心动图用于量化指标，包括右心室分区面积变化（RVFAC）、右心室游离壁纵向应变（RVFWLS）、右心室整体纵向应变（RVGLS）、右心室搏出量（RVSV）和右心室射血分数（RVEF）：PCI术后1周至6个月期间，TAPSE、S'、RVFAC、RVFWLS、RVGLS、RVSV和RVEF均显著增加（P < 0.05）。然而，PCI 术后 6 至 12 个月，RVFAC、RVGLS、RVSV 和 RVEF 没有发生明显变化（P > 0.05）。同时，TAPSE、S'和 RVFWLS 持续显著升高：TAPSE（19.63 ± 3.253% 至 22.603 ± 2.885%，p < 0.001）；S'（10.57 ± 2.643 至 12.61 ± 2.189 cm/s，p < 0.001）；RVFWLS（18.64 ± 2.745% 至 19.926 ± 3.291%，p = 0.002）。PCI术后12个月，S'、RVFAC、RVGLS、RVSV和RVEF仍低于健康对照组，但差异无统计学意义（P > 0.05）。然而，与健康对照组相比，RVFWLS明显降低（19.926 ± 3.291% vs. 22.10 ± 1.994%，P < 0.001）：结论：PCI术后，慢性冠状动脉综合征患者的右心室收缩功能随着时间的推移会明显改善。然而，即使在PCI术后12个月，RVFWLS仍低于对照组。值得注意的是，3D-STE 已成为一种量化慢性冠状动脉综合征患者PCI 后右心室收缩功能的无创方法。
