Coronary Embolism despite CHA₂DS₂-VASc Score of Zero: Should We Reconsider Anticoagulation?

Table 1

Criteria for diagnosis of coronary embolism (Shibata et al.).

---

Criteria for diagnosis of coronary embolism

---

Major criteria

---

 Evidence of coronary embolism or thrombus angiographically without atherosclerosis.

---

 Evidence of coronary emboli to multiple sites concomitantly.

---

 Systemic embolization in the absence of acute myocardial infarction induced left ventricular thrombus.

---

Minor criteria

---

 Stenosis of nonculprit coronary .

---

 Evidence of embolic sources based on noninvasive imaging.

---

 Presence of risk factors for emboli, cardiomyopathy, rheumatic heart disease, prosthetic valve, PFO, atrial septal defect, history of cardiac surgery, infective endocarditis, or hypercoagulable state.

---

Patients with 2 or more major criteria, 1 major and 2 minor, or 3 minor criteria were considered to have a definite coronary embolus. Patients with 1 major and 1 minor or 2 minor criteria were considered to have a probable coronary embolus.
