关于肺栓塞性肺动脉高压(TEPH)的诊断长期来没有很好解决,包括与原发性肺动脉高压症(PPH)的鉴别诊断。近年来,随着右心导管术和肺动脉造影等检查在心脏病学科中的发展,肺血管病的诊断水平逐渐提高。但由于这些检查创伤性等原因,不能反复做,故对于如何鉴别二种不同的肺高压、了解病情、评价疗效是日前临床十分关心和急待解决的问题。现在认为,体液因素对肺循环的调节起重要作用,关于生物活性物质、环核苷酸与肺血
The diagnosis of pulmonary embolism pulmonary hypertension (TEPH) has long been a poorly resolved, including the differential diagnosis of primary pulmonary hypertension (PPH). In recent years, with the right heart catheterization and pulmonary arteriography and other tests in the development of cardiology, the diagnosis of pulmonary vascular disease gradually increased. However, due to these traumatic reasons and other reasons, can not be repeated, so how to identify two different types of pulmonary hypertension, to understand the condition, evaluation of the effect is a very concerned and urgent clinical problems and urgent problems. Now that the humoral factors on the regulation of pulmonary circulation play an important role, on the bioactive substances, cyclic nucleotide and pulmonary blood
