摘要
Pulmonary hypertension (PH) is defined as an increased mean pulmonary artery pressure (P-pa) >25 mmHg at rest as assessed by right heart catheterisation (RHC). However, this technique is invasive and noninvasive alternatives are desirable for early diagnosis of PH. Although estimation of systolic pulmonary arterial pressure is easily obtained using Doppler echocardiography, cases of under- and over-estimations are not rare and direct measurement of P-pa is not possible using this method. Therefore, echocardiography should be considered as a tool for assessment of the likelihood rather than the definite presence or absence of PH. Transthoracic echocardiography may be useful for noninvasive screening of patients at risk of PH. On the basis of an echocardiographic assessment, patients showing signs suggestive of PH can be referred for a confirmatory RHC. A number of variables measured during echocardiography reflect the morphological and functional consequences of PH and have prognostic value. The presence of pericardial effusion, reduced tricuspid annular plane excursion and right atrial enlargement are associated with a poorer prognosis. Echocardiography is also an important procedure for monitoring the response of patients to therapy, and is recommended 3-4 months after initiation of, or a change in, therapy. Echocardiographic assessment as part of a goal-oriented approach to therapy is essential for the effective management of PH patients.
