Clinical characteristics of patients readmitted for stroke with double anti-platelet therapy after percutaneous coronary intervention

摘要

Background The clinical characteristics of stroke patients treated with double anti-platelet therapy(DAPT) after percutaneous coronary intervention(PCI) is not clear. Methods In total, 2675 patients underwent PCI and DAPT in Guangdong General Hospital, and 68 out of them were hospitalized due to suspected stroke, of whom 23 were diagnosed as having stroke. Data of the 23 stroke patients were collected and traditional risk factors associated with stroke were analyzed retrospectively. Results The mean age of these patients was 75.6 ± 8.7 years, and 20(87.0%) were males. Notably, 19 patients were complicated with hypertension, 7 with diabetes mellitus, 7 with previous history of stroke, none with atrial fibrillation(AF) or patent foramen ovale(PFO). Specifically, 22 patients were diagnosed with ischemic stroke, and 1 patient with hemorrhagic stroke. Conclusion Stroke in patients treated with DAPT after PCI was correlated with advanced age, gender, hypertension, diabetes mellitus, stroke history. Long term electrocardiography(ECG)may be needed for the diagnosis of AF, while trans-esophageal echocardiography(TEE) may be needed for PFO.
