The intravascular application of NIR spectroscopy was evaluated in acute myocardial ischemia-reperfusion experiments in animals using the coronary sinus access. Specific NIR absorbance changes during myocardial ischemia. CV, central venous sample. CSn, normal control sample from the coronary sinus blood. CSx, ischemia-related change of NIR spectra pattern after occlusion of the left anterior descending artery. (from: Baykut et al. 200110)
