There are many reports about the association of coronary artery disease (CAD) and cerebral artery stenosis (CAS), which had been proved to induce stroke and cognition decline after the revascularization including coronary bypass surgery (CABG) or percutaneous coronary intervention. Perfusion defect on nuclear brain scan is also noted to correlate with these neurological complications. On the other hand, the perioperative arrhythmia and following cerebral embolism was also attributed to be one factor inducing such neurological hazards.
In the patients with coexistent CAD and CAS (1st group), and also the patients scheduled for CABG or percutaneous coronary intervention (PCI) (2nd group), we, the researchers at Far Eastern Memorial Hospital, attempted to integrate all the parameters mention above, including angiography of coronary and cerebral system, quantitative analysis of nuclear brain scan, biochemical profile, and signals of a new ambulatory device which could record the electrocardiograph (ECG) and electroencephalograph (EEG) simultaneously, in order to define the correlation between them. A chorological relation between EEG signals and ECG signals is our first target to be worked out. Thereafter, we hope to establish a regression model of all involved parameters according to the relation. Such a model, we believe, is essential not only to explain the post-CABG neurological complications, but to prevent them.
Furthermore, for the undetermined ischemic stroke patients who had no obvious culprit artery or embolism source, the paroxysmal arrhythmia had long been regarded as the cause. Whether a paroxysmal atrial fibrillation, which had not been disclosed by routine ECG, could induce most of such a stroke is still not known. With this new ambulatory device which could record the electrocardiograph (ECG) and electroencephalograph (EEG) simultaneously, we want to answer the question.
