概括
肥胖悖论有利于接受心脏再同步治疗 (CRT) 的患者. 接受CRT的肥胖患者与正常体重患者相比,死亡率有所改善,安全性和反应率相似.
科学领域:
- 心脏病学 心脏病学
- 肥胖医学 肥胖医学
- 医疗器械 医疗器械
背景情况:
- 肥胖与更高的心血管风险有关,但在特定的亚组中可能提供更好的结果 (肥胖悖论).
- 关于适应心脏再同步治疗 (CRT) 的患者肥胖悖论的数据有限.
研究的目的:
- 调查身体质量指数 (BMI) 与CRT候选人的全因死亡率之间的关联.
- 为了评估接受CRT的患者的肥胖悖论.
主要方法:
- 在2000-2020年间接受CRT的1585名患者被按BMI分类:正常体重 (<25 kg/m2),超重 (25-<30 kg/m2) 和肥胖 (≥30 kg/m2).
- 主要终点:全因死亡率,心脏移植或左心室辅助装置植入.
- 二级终点包括周围手术并发症和6个月心声回应.
主要成果:
- 与正常体重患者相比,肥胖患者的死亡率有显著的好处 (HR 0.78;P=0.003).
- 在没有糖尿病,心房动或缺血事件的患者中观察到肥胖悖论.
- 在BMI组之间没有注意到周围手术并发症或心声回应的显著差异.
结论:
- 肥胖悖论存在于接受CRT的心力衰竭患者中.
- 接受CRT的肥胖患者,特别是那些没有显著的并发症的患者,比正常体重的患者更有利于死亡率.
- 肥胖在这个CRT队列中没有对安全性或心声回应产生负面影响.

Pathophysiology of Heart Failure
1.5K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Imbalances in Cardiac Output
1.4K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
