肺动脉高压是一组以肺血管阻力进行性增加,最终导致右心增大,右室壁肥厚、右心功能衰竭而死亡的疾病。由于其早期症状和体征的非特异性,肺动脉高压常在晚期阶段才被临床诊断。超声心动图由于其无创、安全、简便易行、重复性高等优点,是诊断肺动脉高压的主要筛查工具。现就不同的超声心动图方法在肺动脉高压评估中的作用做一综述。
Pulmonary hypertension is a group of diseases that progressively increases with pulmonary vascular resistance, eventually leading to an increase in the right heart, hypertrophy of the right ventricle, and right heart failure. Pulmonary hypertension is often clinically diagnosed in advanced stages due to the nonspecificity of its early signs and symptoms. Echocardiography is the primary screening tool for the diagnosis of pulmonary hypertension due to its advantages of being noninvasive, safe, simple, and highly repeatable. The role of different echocardiographic methods in the assessment of pulmonary hypertension is reviewed.
