EXERCISE SEISMOCARDIOGRAPHY FOR RECOGNITION OF RESTENOSIS AFTER CORONARY ANGIOPLASTY

This report summarizes the clinical features of two patients who had r estenosis after coronary angioplasty that was successfully predicted b y exercise seismocardiography, a new noninvasive technique for the det ection of myocardial dysfunction. Furthermore, two clinical trials of exercise seismocardiography and electrocardiography that included pati ents with prior coronary angioplasty are reviewed. Previously unpublis hed sub-group analyses show that, in 49 patients, exercise seismocardi ography had a sensitivity of 81% and a specificity of 83% for detectio n of coronary artery lesions (either restenosis or new lesions) after angioplasty.
