Myth 1 Absence of Classic Chest Pain obviates the need for ACS work up The absence of chest pain in no way excludes the diagnosis of ACS. Around 33-50% of the patients with ACS present to the hospital without chest pain. Close to 20% of patients diagnosed with acute MI present with symptoms other than chest pain.

Other causes of sickling: acidosis, dehydration, inflammation, infection, fever, and blood stasis Sickling leads to vascular occlusion, end-organ ischemia, and decreased RBC lifespan, which, in turn, leads to pain crisis, acute anemia, sequestration, infection, and acute chest syndrome (ACS.) Each episode of ACS has a 9% mortality rate.

What Your Gut Says: The patient has a tachydysrhythmia which may be the presentation of acute coronary syndrome (ACS) even though the patient has no ischemic symptoms. If the patient continues to have symptoms concerning for ACS, troponin testing should be pursued. SVT is not a presenting dysrhythmia consistent w/ ACS.

Sickling leads to vascular occlusion, end-organ ischemia, and decreased RBC lifespan, which, in turn, leads to pain crisis, acute anemia, sequestration, infection, and acute chest syndrome (ACS). ACS is lung injury due to vaso-occlusion in the pulmonary vasculature; many with ACS will have a concomitant vaso-occlusive pain crisis.

Because there was proven thrombus (ACS) but the troponin never went above the 99% reference range (and therefore cannot be called MI -- definition of MI requires rise and/or fall of troponin with at least one value above the 99% reference range), this is UNSTABLE ANGINA with ST Elevation.

A troponin this high in a patient with no known chronic troponin elevation, and active acute ACS symptoms, has a very high likelihood of type 1 ACS regardless of the ECG.
