Abstract: It is intended to evaluate an ischemic heart disease with high accuracy by convenient operation. The method for evaluating an ischemic heart disease according to the present invention comprises the steps of: assaying complement factor H and/or complement factor D in a sample derived from the blood of a test subject; and comparing the concentration of the complement factor H and/or the concentration of the complement factor D assayed in the preceding step with a reference value(s), wherein it is determined that the seriousness of the ischemic heart disease is high when the concentration falls below the reference value.

Abstract: Treatment with an acoustic catheter is disclosed. A photoacoustic catheter system includes an imaging laser beam generator that generates an imaging laser beam used for imaging; a treatment laser beam generator that generates a treatment laser beam used for treatment; a driver that provides driving to cause the imaging laser beam and the treatment laser beam to be emitted in a predetermined direction with respect to an advancing direction of a catheter; an acoustic element that receives an acoustic wave generated due to irradiation of the imaging laser beam; and a treatment laser beam controller, wherein the treatment laser beam controller synchronously emits the imaging laser beam and the treatment laser beam so as to be directionally aligned with each other.

Abstract: The present invention provides a method and a means for evaluating atherosclerotic lesions by identifying a protein (marker protein) group, the expression level of which varies according to the progression of the atherosclerotic lesion, and using the proteins. Specifically, the present invention relates to a method for evaluating atherosclerotic lesions, comprising the steps of detecting a marker protein exhibiting an expression pattern (expression variation) characteristic at a specific disease stage of atherosclerotic lesions in a subject, and evaluating the atherosclerotic lesions in the subject based on the detection result.
