[Diagnosis of pulmonary hypertension secondary to obstructive lung disease by M-mode echocardiography contrasting with right cardiac catheterization].
Fourty five patients with COPD underwent right heart hemodynamics and M-mode echocardiographic study. 5 echocardiographic parameters were screened for diagnosing pulmonary hypertension. Whichever two or more parameters positive were regarded as diagnostic criteria, the sensitivity, specificity and correct rate of diagnosis were 71.43%, 85.00%, and 78.05% respectively. The hemodynamics basis of M-mode echocardiography used for diagnosis of pulmonary hypertension and cor pulmonale was provided in this paper.
