Sent by anonymous, written by Pendell Meyers A man in his 60s presented with acute chest pain with diaphoresis. The ECG was incorrectly interpreted as no signs of ischemia. The Importance of the History: As noted above — the onset of chest pain in today's case was acute. His vitals were within normal limits.

5 Revascularization to improve blood flow to the heart has been shown to reduce mortality in stable chest pain patients. 6 This novel study marks a significant milestone in the field, evaluating the effectiveness of FFR CT in detecting ischemia-producing coronary stenosis in patients with severe PAD. 2024, [link]. 22, 30 Nov.

Written by Willy Frick with edits by Ken Grauer An older man with a history of non-ischemic HFrEF s/p CRT and mild coronary artery disease presented with chest pain. He said he had had three episodes of chest pain that day while urinating. No evidence for ischemia jumps out. ECG 1 What do you think?

An elderly woman presented with chest pain that radiated to the back for several hours. The first troponin returned at 0.099 ng/mL (elevated, consistent with Non-Occlusion MI) Providers were concerned with aortic dissection, so they order a chest aorta CT. Here is here initial ECG: There is only a nonspecific flat T-wave in aVL.
