Patients aged 18 years or older
Must not have
Preexisting distributive shock
Allergy to angiotensin II, angiotensin II or another vasopressor being used at the time of presentation to the operating room

Summary

This trial is testing a new treatment for distributive shock that may help people who have had a heart transplant or implantation of a left ventricular assist device.

Who is the study for?
This trial is for adults who develop distributive shock within 48 hours after a heart transplant or left ventricular assist device (LVAD) placement. They must have specific blood pressure and resistance criteria met, with normal cardiac output. Pregnant or breastfeeding women, those unwilling to consent, patients already on vasopressors before surgery, or with preexisting thromboembolic disease or distributive shock are excluded.
What is being tested?
The study tests Angiotensin II (Giapreza) against a placebo in managing low blood pressure due to distributive shock post-heart surgery. It's a small-scale test involving 40 patients split into two groups: one for heart transplants and another for LVAD implants, each further divided equally between the drug and placebo.
What are the potential side effects?
Potential side effects of Angiotensin II include increased blood pressure, possible clotting issues, and allergic reactions among others not specified here. The exact side effects will be monitored closely given this is an investigational setting.
