Treatment
4.2.2. Acute Chest Pain With Suspected PE
COR LOE
Recommendations
1 B-NR 1. In stable patients with acute chest pain with high clinical
suspicion for PE, CTA using a PE protocol is recommended.
1 C-EO 2. For patients with acute chest pain and possible PE, need for
further testing should be guided by pretest probability.
4.2.3. Acute Chest Pain With Suspected Myopericarditis
COR LOE
Recommendations
1 B-NR 1. In patients with acute chest pain and myocardial injury who
have nonobstructive coronary arteries on anatomic testing,
CMR with gadolinium contrast is effective to distinguish
myopericarditis from other causes, including myocardial
infarction and nonobstructive coronary arteries (MINOCA).
1 B-NR 2. In patients with acute chest pain with suspected acute
myopericarditis, CMR is useful if there is diagnostic
uncertainty, or to determine the presence and extent of
myocardial and pericardial inflammation and fibrosis.
1 C-EO 3. In patients with acute chest pain and suspected
myopericarditis, TTE is effective to determine the presence
of ventricular wall motion abnormalities, pericardial effusion,
valvular abnormalities, or restrictive physiolog y.
2b C-LD 4. In patients with acute chest pain with suspected acute
pericarditis, non-contrast or contrast cardiac CT scanning
may be reasonable to determine the presence and degree of
pericardial thickening.
