The endocardial extent of reperfused first-time myocardial infarction is more predictive of pathologic Q waves than is infarct transmurality: a magnetic resonance imaging study.

abstract：:The purpose of this study was to determine whether exercise modulates the responses of middle cerebral artery blood velocity (MCA V(mean)) and cerebrovascular conductance to sympathetic stimulation (i.e. cold pressor test--CPT).
