ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the feasibility and efficiency of extracorporeal cardiac shock wave therapy (CSWT) for treatment of coronary artery disease.</p><p><b>METHODS</b>Twenty-five patients with 1 - 16 years history of chronic angina pectoris underwent the CSWT. Before and after the treatment, low-dose Dobutamine stress echocardiography and (99)Tc(m)-MIBI myocardial perfusion SPECT were applied to locate the ischemic segments, detect the viable myocardium and evaluate the effect of CSWT. Under the guidance of echocardiography, CSWT was applied in R-wave-triggered manner with low energy (0.09 mJ/mm(2)) at 200 shoots/spot for 9 spots (-1-0-+1 combination). Patients were divided group A and group B. Sixteen patients in group A were applied 9 sessions on 29 segments within 3 month and nine patients in group B were applied 9 sessions on 13 segments within 1 month. Ten chronic angina pectoris patients receiving standard medication served as controls.</p><p><b>RESULTS</b>All patients completed the 9 sessions without procedural complications or adverse effects. CSWT significantly improved symptoms as evaluated by NYHA, Canadian Cardiovascular Society (CCS) class sores, Seattle angina questionnaire (SAQ), 6-min walk and the use of nitroglycerin (P < 0.05). CSWT also improved myocardial perfusion and regional myocardium function as evaluated by rest SPECT and stress peak systolic strain rate (PSSR) (P < 0.01). Myocardial perfusion improvement was more significant in group A compared with group B (1.21 ± 0.86 vs. 0.83 ± 0.80, P < 0.01). All parameters remained unchanged in control group during follow up.</p><p><b>CONCLUSION</b>These preliminary results indicate that CSWT is safe and effective on ameliorating anginal symptoms for chronic angina pectoris patients.</p>
