Minimal Lesion Syndrome
After initiation of thrombolytic therapy for patients with acute myocardial infarction, minimal lesion syndrome is defined as the presence of an insignificant (≤50%) residual coronary obstruction of infarct-related artery vessel on coronary angiography. Despite insignificant reduction in the lumen diameter, in situ thrombosis or minimal intimal irregularities is usually present. Coronary vasospasm with subsequent thrombus formation overlying a minimally encroaching atherosclerotic plaque is implicated in the pathogenesis for minimal lesion syndrome, and these patients are typically young male and heavy smokers.[1] Smoking cessation and empirical use of nitrates or calcium channel blockers are required. In light of the unfavorable prognosis in a subset of these patients, longer follow-up may be needed to determine the risk for rethrombosis events.[2]
