The aim of this study was to evaluate and investigate the pathogenetic mechanism and countermeasures of subacute thrombosis (SAT) after coronary stenting in elderly diabetic patients. The clinical characteristics and pathogenetic mechanisms in 3 cases of SAT after stent implantations in elderly diabetic patients were retrospectively examined to determine the treatment strategies for SAT. Among 98 patients with diabetes who had coronary stents implanted or were >60 years of age, three (3.06%)

... SAT. One case of SAT was diagnosed by angiography; coronary balloon dilatation, thrombolysis, and reperfusion resulted in full recovery in this case. The second case involved potential SAT, and in the third case, SAT was not ruled out. Two cases were characteristic of ST-segment elevation myocardial infarction, and one case, in which SAT was not ruled out, resulted in sudden death.
