概括
严重的左心室缩 (LVH) 与在脑内出血 (ICH) 后更多的扩散加权成像 (DWI) 病变有关. 心声学可以帮助识别患有二次性缺血风险的患者.
科学领域:
- 神经学 神经学
- 心脏病学 心脏病学
- 放射学 放射学是指放射学
背景情况:
- 大脑缺血在脑内出血 (ICH) 后很常见,并且与不良结果有关.
- 由于高血压导致的大脑自调节受损是一个可疑的原因.
- 左心室缩 (LVH) 是慢性高血压的标志物,研究了它与DWI病变的关联.
研究的目的:
- 测试假设,更大的LVH严重程度与扩散加权成像 (DWI) 病变后ICH相关.
- 为了探索LVH作为二次性缺血的预测者后ICH.
主要方法:
- 一个单中心观察队列研究包括187名患有自发性ICH的患者.
- 胸外心声学 (TTE) 评估了LVH (分类为没有/轻度与中度/严重) 和左心室质量指数 (LVMI).
- 大脑MRI发现了急性DWI病变,病变数作为次要结果.
主要成果:
- 在23.5%的患者中存在中度/严重的LVH;在30.5%的患者中检测到DWI病变.
- 中度/重度的LVH与DWI病变存在 (aOR2.74 ,p=0.01) 和数量 (aB1.32 ,p<0.01) 有显著的关联.
- 较高的LVMI四分位数也与增加的DWI病变存在相关 (aOR3.60,p=0.01).
结论:
- 增加的LVH严重程度与DWI病变的存在和负担相关,急性ICH.
- 心声学可以帮助二次性缺血的风险分层和ICH患者的预防策略.

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
