概括
在ST段升高心肌梗塞 (STEMI) 患者的心肌梗塞后心肌梗塞 (PMIP) 与心脏功能恶化和心肌损伤增加有关. 然而,PMIP在随访期间不会增加心脏不良事件的风险.
科学领域:
- 心脏病学 心脏病学
- 放射学 放射学是一门学科.
- 内部医学 内部医学
背景情况:
- 心肌梗塞后心脏膜炎 (PMIP) 是ST段升高心肌梗塞 (STEMI) 后的一种已知的并发症.
- 了解与PMIP相关的因素及其临床影响对于患者管理至关重要.
研究的目的:
- 调查STEMI患者中PMIP的人口,实验室,临床和心血管磁共振 (CMR) 相对应物.
- 评估PMIP对心脏功能和长期结果的影响.
主要方法:
- 对122名STEMI患者的CMR扫描进行了回顾性分析.
- 通过T2-STIR和/或晚期加多增强 (LGE) 序列的心周增强来定义PMIP.
- 患者与没有PMIP之间的心脏功能参数和不良事件的比较.
主要成果:
- 在PMIP患者中,左下心室排气分数和右心室末缩体积指数较高.
- 在PMIP患者中观察到心房水库应变,全球辐射应变和全球纵向应变的损伤.
- 较大的LGE范围和乳头肌肉参与与PMIP相关;心房水库应变和全球纵向应变是独立的预测因素.
结论:

Pericarditis II: Clinical Features and Diagnostic Tests
270
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Myocarditis II: Clinical Features and Diagnostic Tests
242
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...

Imaging Studies for Cardiovascular System IV: CMRI
300
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Myocarditis I: Introduction
347
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...

Pericarditis I: Introduction
301
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of 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...
