JAHA:左心室舒张功能正常的患者肺动脉高压与全身动脉高血压相关

2021-12-08 MedSci原创 MedSci原创

无论左心疾病状态如何,肺动脉高压都与全身性动脉高血压相关。这种关联在女性中更为明显。

肺动脉高压和全身动脉高压之间的关联被认为是通过高血压左心疾病介导的。

近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,该研究的目的是调查肺动脉高压是否与左心室舒张功能正常的患者全身动脉高血压相关。

研究人员连续招募了2007年至2019年间进行超声心动图检查的患者。患有已知的与肺动脉高压相关的疾病状态的患者,包括舒张功能障碍,被排除在该研究的分析之外。研究人员从超声心动图检查报告中提取所有患者估计的右心室收缩压。肺动脉高压被定义为估计的右心室收缩压40mmHg以上。研究人员采用多变量Logistic回归模型进行了分析。

最终的研究人群包含25916名中位年龄为59(四分位距为44-69)岁的患者,其中12501名(48%)患者为男性,13265名(51%)患者伴有全身性动脉高血压。与血压正常的患者相比,高血压患者发生肺动脉高压的可能性高出3.2倍(95%CI为2.91-3.53;P<0.001)。对已知的与肺动脉高压相关的临床和超声心动图参数进行调整的多变量模型表明,高血压患者患肺动脉高压的可能性几乎是其3倍(95%CI为2.45-3.15;P<0.001)。这种关联在多个亚组中显著,但在女性中比男性更为显著(比值比为3.1 vs. 2.4;交互作用P<0.001)。

由此可见,无论左心疾病状态如何,肺动脉高压都与全身性动脉高血压相关。这种关联在女性中更为明显。

肺动脉高压引起右心衰竭的病理生理学

当心脏的 RV 无法将血液泵送到肺部以满足需求时,这种情况称为 RVF。由于解剖学和生理学上的差异,两个心室对压力的反应相反。迄今为止,可用于 RVF 的传统疗法无法提供任何令人信服的结果。

肺动脉高压新的风险评分的变化可预测患者预后

风险评估在肺动脉高压 (PAH) 管理中至关重要。我们调查了riociguat对 REVEAL Lite 2 评分的影响,REVEAL 风险评分的删节版,及其与 PATENT 中长期结果的关联。

β-抑制蛋白介导的血管紧张素II受体激活促进肺动脉高压患者的肺血管重塑

AT1R β-抑制蛋白偏向激动剂可促进血管重构并使PAH恶化,这表明当前 PAH 疗法的主要益处是通过肺血管逆转重构以及血管舒张。

三尖瓣反流速度评估肺动脉高压对瓣膜置换术后的长期预后意义

肺动脉高压(PH)指南提出的三尖瓣反流速度(TRV)的生理阈值上限为2.8 m/s受到质疑。本研究的目的是使用两种不同的TRV阈值评估术前肺动脉高压对瓣膜置换术后长期主动脉瓣狭窄患者的预后意义。

雷帕霉素和低剂量伊马替尼联合治疗肺动脉高压

人肺动脉平滑肌细胞的增殖增强和远端迁移都有助于肺血管重塑和肺动脉高压 (PAH) 阻力的逐渐增加。本研究的目的是评估针对 mTOR 信号传导和 PDGFR 抑制的联合疗法在减弱PAH的进展作用。
