研究目的: |
本研究旨在通过一项前瞻性观察性研究,系统探讨肥厚型梗阻性心肌病(HOCM)患者术前存在的室性心动过速(室速)对室间隔切除术后近期疗效与长期预后的影响。 次要目的:利用术中获取的心肌标本,探索伴与不伴术前室速的HOCM患者在心肌微观结构与细胞分子层面的差异,为临床表型差异提供机制解释。 |

Objectives of Study: |
This study aims to systematically investigate the impact of preoperative ventricular tachycardia (VT) on short-term efficacy and long-term prognosis in patients with Hypertrophic Obstructive Cardiomyopathy (HOCM) undergoing septal myectomy, through a prospective observational study. A secondary objective is to utilize intraoperatively acquired myocardial specimens to explore the differences in myocardial microstructure and cellular molecular profiles between HOCM patients with and without preoperative VT, thereby providing a mechanistic explanation for the observed clinical phenotypic differences. |
