ABSTRACT
PURPOSE:
Although asymptomatic coronary artery occlusive disease is common in stroke patients, the long-term advantages of undergoing evaluation for coronary arterial disease using multi-detector coronary computed tomography (MDCT) have not been well established in stroke patients. We compared long-term cardio-cerebrovascular outcomes between patients who underwent MDCT and those who did not. MATERIALS ANDMETHODS:
This was a retrospective study in a prospective cohort of consecutive ischemic stroke patients. Of the 3117 patients who were registered between July 2006 and December 2012, MDCT was performed in 1842 patients [MDCT (+) group] and not in 1275 patients [MDCT (−) group]. Occurrences of death, cardiovascular events, and recurrent stroke were compared between the groups using Cox proportional hazards models and propensity score analyses.RESULTS:
During the mean follow-up of 38.0±24.8 months, 486 (15.6%) patients died, recurrent stroke occurred in 297 (9.5%), and cardiovascular events occurred in 60 patients (1.9%). Mean annual risks of death (9.34% vs. 2.47%), cardiovascular events (1.2% vs. 0.29%), and recurrent stroke (4.7% vs. 2.56%) were higher in the MDCT (−) group than in the MDCT (+) group. The Cox proportional hazards model and the five propensity score-adjusted models consistently demonstrated that the MDCT (−) group was at a high risk of cardiovascular events (hazard ratios 3.200, 95% confidence interval 1.172–8.735 in 11 propensity matching analysis) as well as death. The MDCT (−) group seemed to also have a higher risk of recurrent stroke.CONCLUSION:
Acute stroke patients who underwent MDCT experienced fewer deaths, cardiovascular events, and recurrent strokes during follow-up.
