| ==Diagnosis==
| |
| * In primary pulmonary hypertension the [[pulmonary artery]] diastolic pressure is much higher than the [[pulmonary capillary wedge pressure]].
| |
| * If the pulmonary hypertension is due to left-sided heart failure, and the pulmonary artery diastolic pressure in the pulmonary capillary wedge pressure will be similar.
| |
| * In the cardiac catheterization laboratory, inhaled nitric oxide is administered to determine if the pulmonary vasculature is still reactive or if the obstructionist fixed.
| |
| * It is to get dangerous to give nifedipine IV as a test. This could lead to a dangerous episode of [[hypotension]].
| |
|
| |
| ==Treatment==
| |
| ===Pregnancy===
| |
| * Patients with pulmonary hypertension should avoid pregnancy
| |
| ===First-Line Therapies===
| |
| * First-line therapies or type I pulmonary hypertension or world of organization class to pulmonary hypertension include [[bosentan]], [[ambrisentan]] and Viagra
| |
| ===Calcium Channel Blockade===
| |
| * [[Nifedipine]] can be used in these patients, but should not be given to patients who are not reactive to inhaled nitric oxide as it will not work in that scenario. Calcium channel blocker should not be used in patients with Eisenmenger syndrome.
| |
| === Advanced Pulmonary Hypertension===
| |
| * The prostaglandins can be useful in these patients and include [[epoprosterol]] and [[iloprost]].
