ABSTRACT

Pulmonary hypertension (PHT), is a cause of progressive damage of right ventricular function with bad prognosis in short time. The PHT can be suspected, when a patient refers dyspnea, syncope, fatigue and hoarseness without any explanation. In healthy subjects (‹ 50 years) the normal systolic pressure (PAPs) range is from 18-30 mmHg and a mean pulmonary arterial pressure (PAPm) ranges is from 10-15 mmHg. PHT secondary to other chronic respiratory diseases is defined for a PAPm ( 20 mmHg by means of right heart catheterization (RHC) at rest, and PAPs ( 30 mmHg by echocardiography (ECO). Diagnosis of PHT is doing for exclusion, however there are numerous algorithms accepted in different medical centers around the world. But, as many guide lines, those have been modified because specific medical situations. The principal objectives of that study are: to exclude secondary causes of PHT, classify the severity of pulmonary hemodynamic findings and the vasodilators effects in acute changes during RHC. In this review, we reported the most relevant features for the clinical evaluation of PHT.
