Risk factors and prognosis of acute ischemic stroke after coronary angiography and percutaneous coronary intervention

Aim: Aim of this study is to analyze the incidence, predictors and outcomes of stroke in patients who underwent coronary angiography and percutaneous coronary intervention at our center. Materials-Methods: This study was conducted in a tertiary health center in Ankara/Turkey. Sixteen patients who had a stroke after coronary angiography and percutaneous coronary intervention were included in the study as a case group. The control group consisted of 80 patients. It is a retrospective study. Hemorrhagic stroke cases were excluded. All participants are ischemic stroke cases. Results: The average age of the participants is 69.6+12.1 years. Of the participants, 59 (61.5%) were male and 37 (38.5%) were female. The incidence of symptomatic cerebral infarction after coronary angiography or percutaneous coronary intervention was 16 cases (0.16%). Coronary angiography and percutaneous coronary intervention was performed in eight patients. No significant difference was observed between the groups in terms of use of antiplatelet drugs, statins, beta-blockers, warfarin or oral anticoagulants. Conclusion: Multi-vessel disease, conjestive heart failure, low ejection fraction and chronic renal failure were found to be risk factor for the development of coronary angiography or percutaneous coronary intervention related stroke.
