Hemodynamic testing to guide vasodilator therapy in cardiac amyloidosis.

Medications that cause peripheral vasodilation are standard therapy for patients with reduced ejection fraction, however, they are seldom used for patients with cardiac amyloidosis due to adverse effects. In some cases, there may be value in using hemodynamic measurements in patients with advanced cardiac amyloidosis to guide management as some patients may have hemodynamics that resemble those of systolic heart failure. This may offer a novel approach to symptomatic treatment of advanced cardiac amyloidosis.
