[show abstract] [hide abstract]
ABSTRACT: Our aim was to evaluate the safety and effectiveness of extracorporeal cardiac shock wave therapy (CSWT) for the patients with coronary heart disease (CHD) using a randomized, double-blind, controlled clinical trial design. Twenty-five patients with CHD were enrolled in this study. Fourteen of the patients were randomized into the CSWT group and 11 into the control group. We applied the CSWT procedure to each patient by using nine shock treatments during 3 months, but the shock wave (SW) energy was only applied to the patients in the CSWT group and not to the patients in the control group. Technetium-99m sestamibi myocardial perfusion, fluorine-18 fluorodeoxyglucose myocardial metabolism single-photon emission computed tomography (SPECT), and two-dimensional echocardiography were performed to identify segments of myocardial ischemia, myocardial viability, and ejection fraction before and after CSWT. We also followed the patients to evaluate adverse effects. After CSWT, the New York Heart Association class, the Canadian Cardiovascular Society angina scale, nitroglycerin dosage, myocardial perfusion and myocardial metabolic imaging scores of dual-isotope SPECT in the CSWT group were reduced significantly (P = 0.019, 0.027, 0.039, 0.000, 0.001, respectively), and the Seattle Angina Questionnaire scale, 6-min walking test, and left ventricular ejection fraction were increased significantly (P = 0.021, 0.024, 0.016, respectively) compared with those before the SW treatment. All of the parameters in the control group did not change significantly after the treatment (all P > 0.05). No serious adverse effects of CSWT were observed. Cardiac shock wave therapy is a safe and effective treatment for CHD patients.Heart and Vessels 03/2012; · 2.05 Impact Factor -

ABSTRACT: To evaluate the feasibility, safety and efficiency of extracorporeal cardiac shock wave therapy (CSWT) in patients with ischemic heart failure. Fifty patients with ischemic heart failure and left ventricular ejection fraction (LVEF) < 50% were randomized to CSWT (shots/spot at 0.09 mJ/mm(2) for 9 spots, 9 times within 3 month) or control group. Dual isotope simultaneous acquisition single-photon emission computed tomography with (99)Tc(m)-sestamibi/(18)F-fluorodeoxyglucose ((99)Tc(m)-MIBI/(18)F-FDG) was performed before randomization and at 1 month after CSWT/control to locate and evaluate viable myocardium region. Canadian cardiovascular society (CCS) class sores, NYHA, Seattle Angina Questionnaire (SAQ), 6-min walk test (6 MWT), left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD) and the dosage of nitroglycerin use were compared between two groups at each time point. All patients completed the study protocol without procedural complications. At 1 month, patients in CSWT group experienced improvement in NYHA (P < 0.01), CCS (P < 0.01), SAQ (P = 0.021), 6 MWT (P = 0.012) and dosage of nitroglycerin use (P < 0.01) compared to baseline. LVEF [45.0 (39.0, 48.0) vs. 47.0 (42.0, 50.0) P = 0.001], LVEDD [58.0 (56.0, 59.0) vs. 56.0 (55.0, 58.0) P = 0.002], summed perfused score [23.0 (20.5, 24.5) vs. 20.0 (18.0, 22.0) P < 0.01] and metabolic score [25.0 (23.0, 26.0) vs. 24.0 (21.5, 25.0) P = 0.028] were also improved in CSWT group. All these parameters remained unchanged in control group between baseline and at 1 month. CSWT was independent factor for improved cardiac function, quality of life and echocardiography parameters after adjusting for known factors which might affect outcome. CSWT could improve symptom, cardiac function, quality of life and exercise tolerance in patients with ischemic heart failure, CSWT might serve as a new, non-invasive, safe and efficient therapy for these patients.Zhonghua xin xue guan bing za zhi [Chinese journal of cardiovascular diseases] 02/2012; 40(2):141-6.
