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.

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.

Written by Jesse McLaren, with edits from Smith and Grauer A 60 year old with no past medical history presented with two hours of chest pain radiating to the left arm, with normal vitals. 2] Conduction through the accessory pathway can be intermittent (with different degrees of pre-excitation), and affected by ischemia.

Together, the two companies will work to further the development and commercialization of Medis Quantitative Flow Ratio (Medis QFR), a non-invasive approach to the assessment of coronary physiology, as part of GE HealthCare’s interventional cardiology portfolio built around the Allia Platform.

Context: a man in his 40s presented to the emergency department with 1 day of sudden onset chest pain. Serial echo monitoring showed increasing pericardial pressures without overt tamponade physiology. That said — I did not interpret these differences as the result of acute ischemia. Pericarditis maybe."

It was edited by Smith CASE : A 52-year-old male with a past medical history of hypertension and COPD summoned EMS with complaints of chest pain, weakness and nausea. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.
