概括
发性心肌炎 (FM) 患者的左心室喷射率 (LVEF) 比非FM患者要低得多. 早期使用大动脉内气球 (IABP) 和体外膜氧化 (ECMO) 可以改善 FM 患者的 LVEF.
科学领域:
- 心脏病学 心脏病学
- 内部医学 内部医学
- 关键护理医学 关键护理医学
背景情况:
- 在比较发性心肌炎 (FM) 和非FM (NFM) 患者之间的左心室喷射率 (LVEF) 变化方面存在知识差距.
- 急性心肌炎的诊断通常通过心脏内膜活检 (EMB) 或心脏磁共振成像 (CMR) 得到确认.
研究的目的:
- 为了比较 FM 与 NFM 患者的 LVEF 随时间变化.
- 评估机械循环支持对 FM 患者 LVEF 的影响.
主要方法:
- 一项多中心回顾性研究包括324名确诊患有急性心肌炎的患者.
- 使用混合效应模型和多模型调整来分析LVEF变化.
- 对15岁及以上的患者进行了敏感性分析.
主要成果:
- 与NFM患者相比,FM患者在随访时具有较低LVEF (<55%) 的风险明显更高 (OR=7.438,P<0.001).
- 与FM患者相比,NFM患者在所有随访间隔中表现出优异的LVEF.
- 动脉内气球 (IABP) 和体外膜氧化 (ECMO) 的早期使用与 FM 患者的 LVEF 改善有关 (OR=0.030,P=0.001 对于 IABP;OR=0.339,P=0.030 对于 ECMO).
结论:
- 发性心肌炎与与非发性心肌炎相比持续较低的LVEF有关.
- 早期实施IABP和ECMO可能会改善FM患者的长期LVEF结果.

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

23
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

52
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...

Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...
