Brief summary
The purpose of this study is to determine the effectiveness of cardiac shock wave therapy (CSWT) for the treatment of severe coronary artery disease (CAD) in a Chinese cohort.
Detailed description
This study was approved by the Institutional Review Board and Ethics Committee of 1st Hospital of Kunming Medical University, and all study subjects signed informed consent for participation in the study and all treatments performed. Subjects were patients who were hospitalized at Department of Cardiology of our hospital from December 2008 to December 2009. Patients were eligible to be included in the study if they met any of the following criteria: 1) Coronary angiography (CA) or multi-slice CT coronary angiography (CTCA) suggestive of moderate to severe coronary artery stenosis. 2) Chest tightness, onset of shortness of breath, and poor exercise tolerance after receiving formal drug treatment (with or without stent or bypass graft). 3) Hospitalized more than 2 times within 1 year due to the aforementioned problems. 4) CCS angina grading higher than grade II, and NYHA functional classification of I-III. 5) More than 1 month after acute myocardial infarction (AMI) and more than 2 weeks after PCI surgery. The diagnosis and treatment in all the patients was in accordance with the related domestic and European guidelines developed in 2007
Interventions
DEVICEcardiac shock wave therapy(CSWT)
CSWT was performed with the MODULITH SLC SW therapy device (Storz Medical, Switzerland).Shock waves were triggered by the R-wave of the ECG when the instrument was activated. The shock wave energy was increased from an initial low level up 0.09 mJ/mm2 if the patient experienced no discomfort such as chest pain. Point-to-point combination treatment for the ischemic areas with 200 pulses delivered to each point was given.
