研究目的: |
本研究旨在应用心脏做功分析等超声心动图新技术,评估室性期前收缩患者(特别是高负荷患者)的早期心功能变化,并与心脏结构及功能正常的健康对照组进行比较。通过对比,深入探究室性期前收缩对心肌力学及收缩储备的潜在影响,识别其在心脏整体功能受损前的亚临床异常特征。 |

Objectives of Study: |
This study aims to apply new echocardiographic techniques such as cardiac work analysis to evaluate early changes in cardiac function in patients with ventricular premature contractions (especially those with high burden), and compare them with healthy control groups with normal cardiac structure and function. Through comparison, it will deeply explore the potential impact of ventricular premature contractions on myocardial mechanics and contractile reserve, and identify subclinical abnormal features before overall cardiac function is impaired. |

1. Transthoracic echocardiography indicating left ventricular ejection fraction (LVEF) <50%. 2. Clinical diagnosis of heart failure, including heart failure with preserved ejection fraction (HFpEF, EF>=50% and NT-proBNP>125 pg/mL), consistent with the recommendations of the "2021 ESC Guidelines for the Diagnosis and Treatment of Acute and Chronic Heart Failure". 3. Patients with arrhythmias other than premature ventricular contractions and short runs of ventricular tachycardia (such as atrial fibrillation, atrial flutter, frequent premature atrial contractions, conduction system diseases, etc.). 4. Currently using Class I/III antiarrhythmic drugs (AAD) or undergoing ablation therapy. 5. Other known diseases affecting left ventricular function, including hypertension, coronary artery disease, valvular heart disease, congenital heart disease, pulmonary heart disease, thyroid disease, severe hepatic or renal insufficiency, and other conditions affecting left ventricular function. 6. Patients with poor echocardiographic image quality that does not meet image analysis requirements. |

盲法: |
本研究采用单盲设计。为减少测量偏倚,所有受试者的超声检查及后续数据分析均由对分组情况完全不知情的医师完成。待全部数据采集完毕后,再由研究员根据编号回溯匹配临床分组 |
|
Blinding: |
This study used a single-blind design. To reduce measurement bias, all ultrasound examinations and subsequent data analysis were performed by physicians unaware of group assignments. After data collection was complete, researchers matched clinical groups by reviewing the assigned codes. |
