OBJECTIVE: Many studies have found a beneficial effect of Extracorporeal Shockwave Myocardial Revascularization (ESMR) therapy for refractory angina patients. However, clinical studies ESMR therapy for indicated coronary artery bypass grafting (CABG)-stable angina pectoris (SAP) patients are limited.

PATIENTS AND METHODS: Four indicated CABG-SAP patients CCS class I-III reviewed in this study. All patients refuse to CABG procedure. Data of myocardial perfusion and function from medical records were collected.

RESULTS: After ESMR therapy, summed rest score was improved in patient 1 from 14 to 8, Patient 2 from 10 to 5, and Patient 3 from 6 to 4. Summed stress score was improved in patient 1 from 31 to 19. Left ventricular ejection fraction was improved in patient 1 at rest from 59 to 67% and stress from 39 to 57%. The global longitudinal strain was improved in patient 1 from -16 to -20.9 and Patient 3 from -14.8 to -18.2. Diastolic dysfunction severity was improved in patient 2 and patient 3 from grade 2 to grade 1.

CONCLUSIONS: In our case series, ESMR therapy for indicated CABG-SAP patients might improve myocardial perfusion and function, especially for patients with a high ischemic burden.
