The timely detection of myocardial fibrosis is crucial for intervention and improved outcomes. 68 Ga-FAPI-04 PET/CT shows promise in assessing fibroblast activation in patients with early myocardial infarction characterized by prolonged myocardial ischemia. The results demonstrated tracer-specific uptake (SUVmax = 4.6)

Cardiovascular consultation had been requested for all of the patients based on their primary clinical examination, vital signs, and electrocardiogram (ECG). Additionally, 2D transthoracic echocardiography (TTE), and myocardial injury serum biomarkers assays (creatine phosphokinase-MB [CPK-MB] and cardiac troponins [cTn]) were measured once.

Non-STEMI guidelines call for “urgent/immediate invasive strategy is indicated in patients with NSTE-ACS who have refractory angina or hemodynamic or electrical instability,” regardless of ECG findings.[1] 1] European guidelines add "regardless of biomarkers".

As hours go by, these T inversions always evolve , [unless 1) there is re-occlusion, in which case they go upright and become hyperacute, with or without additional ST elevation, ("pseudonormalize") or 2) no infarction at all (negative troponin, true unstable angina with dynamic T-waves, in which they may normalize).

A middle aged male with no h/o CAD presented with one week of crescendo exertional angina, and had chest pain at the time of the first ECG: Here is the patient's previous ECG: Here is the patient's presenting ED ECG: There is isolated ST depression in precordial leads, deeper in V2 - V4 than in V5 or V6. There is no ST elevation.
