Khảo sát đặc điểm lâm sàng, cận lâm sàng và đặc điểm kỹ thuật của phương pháp sóng xung kích ở bệnh thiếu máu cơ tim cục bộ mạn tính

Abstract

Objective: To investigate the clinical, subclinical and technical characteristics of shock wave therapy in patients with ischemic heart disease. Subject and method: This is a prospective, cross-sectional study on 65 patients with ischemic heart disease with indications cardiac shock wave therapy managed at Internal Cardiology Department of the 108 Military Central Hospital from March 2017 to March 2021. All patients were performed clinical examination and laboratory tests, learn risk factors onset. Result: The average age of the study group was 72.2 ± 10.1 years, men accounted for 78.5%. The rate of chest pain grade of CCS 2 (24.6%); CCS 3 (58.5%); CCS 4 (16.9%). There was no sign of myocardial ischemia on the electrocardiogram (30.3%), old myocardial infarction accounted for 32.2%. Ejection fraction (EF) Simsons 44.89 ± 12.27%, wall motion septal index (WMSI) 1.54 ± 0.18; global longitudinal strain (GLS) -10.28 ± 2.82. The number of patients without intervention were 27.7%, with PCI (61.5%), with CABG (7.7%), with PCI and CABG (3.1%). Damage to multiple branches of coronary artery (55.4%). Severe severity of multiple coronary artery stenosis (50.8%). The percentage of severe perfusion defects (46.2%) and large perfusion defect (60%). Average total pulse output 6269.2 ± 816.6 pulses. The average number of zones and pulse generation time were 7.72 ± 1.48 zones and 128.6 ± 45.64 minutes, respectively. The highest percentage of pulsed areas was the apical region (93.8%), the lowest was the lateral wall 30.2%. There was no rise of cardiac enzymes and complicated arrhythmias were not observed during the study period. Conclusion: Patients with chronic ischemic heart disease in shockwave therapy treatment group are often older, have many risk factors, coronary artery lesions are many and complicated, and the degree of perfusion defect is severe and extensive.
