Abstract
Quantitatively determining an amount of reperfusion in an artery after angioplasty and quantitatively assessing an effectiveness of thrombolysis by non-invasively sensing from outside the subject mechanical vibrations from a mechanical contraction of at least one ventricle to simultaneously measure (a) IVCT (time duration of an isovolumetric contraction portion of a systole phase) and (b) a peak endocardial acceleration (PEA) during the IVCT. PEA is measured before and after opening the artery (or before and after thrombolysis) and in some embodiments one calculates a myocardial contractility index (MCI) of the subject, for example MCI=PEA/IVCT. A determination unit compares the first and second PEA (or the first and second MCI), and then determines an amount of reperfusion based on the comparison. The amount of reperfusion is proportionate to a viable myocardium and, in the case of thrombolysis, the amount of reperfusion quantitatively assesses the effectiveness of thrombolysis.
