Study Summary

The goal is to determine whether fentanyl and morphine have similar effects in reducing aspirin's effect upon platelets in emergency department patients with chest discomfort. Morphine has been shown to worsen outcomes in heart attack patients due to reduction of oral anti-platelet agent effectiveness and so many providers have switches to using fentanyl. However, it is largely unknown whether fentanyl has similar effects.

Primary Outcome

Arachidonic Acid Maximum Aggregation is assessed using light transmission aggregometry (LTA). This method involves adding arachidonic acid to platelet-rich plasma (PRP) and measuring the change in light transmittance as platelets aggregate. The maximum aggregation percentage is recorded as the highest point of aggregation observed during the test. From a clinical perspective, normal aggregation is considered 70% or higher and values below 70% may indicate platelet dysfunction or the influence of
