RJ is a 47-year-old man with a past medical history of sickle cell disease, severely depressed right ventricular systolic function, who has been newly diagnosed with primary pulmonary hypertension on right heart catheterization. He has a positive response to adenosine vasodilator challenge during catheterization. His pulmonary artery systolic pressure is 60 mm Hg. He is in functional class III. His current medications include: warfarin 10 mg daily, metoprolol 25 mg twice daily, furosemide 20 mg twice daily, hydroxyurea 500 mg daily, and risperidone 4 mg at bedtime. His heart rate is 67 beats/minute and blood pressure is 118/57 mm Hg. Which medication should RJ be initiated on to prevent mortality and progression of his pulmonary hypertension?

(A) epoprostenol 2 ng/kg/minute(B) diltiazem 240 mg daily(C) bosentan 62.5 mg PO twice daily(D) inhaled iloprost 2.5 mcg x1, then 5 mcg/inhalation through nebulizer 6–9 times daily

In patients with an acute vasodilator response to challenge during right heart catheterization, they should receive a calcium channel blocker to prevent mortality. In this patient, metoprolol may require dosage reduction or substitution with an ACE inhibitor to allow adequate blood pressure and heart rate for diltiazem therapy. Alternatively, amlodipine could be utilized if the patient has to remain on metoprolol but his heart rate cannot tolerate both diltiazem and metoprolol together. All alternative vasodilators should be reserved for patients who do not respond adequately to a vasodilator challenge during catheterization or who are failing calcium channel blocker therapy. Epoprostenol should be reserved for those in functional class IV to prevent mortality and also should be reserved as an alternative to patients who do not respond to or are failing calcium channel blockers.

There are several antihypertensive agents available including esmolol, nicardipine, labetalol, and fenoldopam. While sodium nitroprusside is a rapid-acting and potent antihypertensive agent, it may be associated with significant toxicity and should therefore be used in select circumstances at a dose not to exceed 2 μg/kg/min. The appropriate therapeutic approach of each patient will depend on the clinical presentation of the patient. Agents such as nifedipine and hydralazine should be abandoned because these agents are associated with significant toxicities and/or side effect profile.
