概括
左心室缩 (LVH) 分级和左心室全球纵向应变 (GLS) 损伤预测了法布里病的主要不良心血管事件 (MACE). 将这些评估结合起来,可以改善风险分层,从而改善患者的治疗结果.
科学领域:
- 心脏病学 心脏病学
- 遗传学 遗传学 是一个
- 生物标志物 生物标志物
背景情况:
- 在法布里病中,左心室缩 (LVH) 和机械功能的预后值尚未明确.
- 费布里病是一种遗传性疾病,可能导致心血管并发症.
研究的目的:
- 评估LVH严重程度,LV机械功能和法布里病患者的临床结果之间的关联.
- 确定LVH分级和LV机械功能是否可以预测主要不良心血管事件 (MACE).
主要方法:
- 对268名成年法布里病患者进行了回顾性队列研究.
- 左心室质量指数 (LVMI) 评估了使用性别特异性切除值来评估LVH严重程度.
- 左心室全球纵向应变 (GLS) 通过斑点追踪分析测量.
- 主要结局:MACE的5年复合 (心力衰竭住院,持续的心室动脉冲动,中风,全因死亡率).
主要成果:
- 106名患者 (39.6%) 患有 LVH. 5年MACE发生率随着LVH严重程度的增加 (轻度7.4%,中度10%,严重30.5%).
- 损伤的LV GLS (<14.1%) 与显著更高的5年MACE率 (32.1%对2.4%) 相关.
- 严重的LVH独立预测MACE (aHR 12.73),并结合严重的LVH与受损的LV GLS显示了最高的MACE发病率.
结论:
- 通过LVMI对性别特定的LVH分级对于风险分层的法布里病患者来说是实用的.
- 损伤的LV GLS进一步细化预后,特别是在与严重的LVH结合时.
- 这些参数有助于识别针对性干预的高风险个体.

Pathophysiology of Heart Failure
1.6K
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...
