概括
系统性硬化症患者经历心脏性休克和急性心室功能障碍的死亡率很高. 心肌炎是可能的原因,表明需要更好的心脏护理系统性硬化症.
科学领域:
- 心脏病学 心脏病学
- 类风湿病学 类风湿病学
- 病理学 病理学 病理学
背景情况:
- 心脏参与是系统性硬化症 (SSc) 死亡的主要原因.
- 在SSc患者中,急性心室功能障碍和心脏性休克有不清楚的潜在原因.
- 这项研究调查了急性心室功能障碍和心脏性休克的SSc患者的特征和结果.
研究的目的:
- 为了阐明急性心室功能障碍的临床,成像和病理特征,系统性硬化症 (SSc) 患者呈现心脏性休克.
- 评估这个患者队列的住院和六个月的结果.
- 确定SSc.中心脏功能障碍的潜在驱动因素.
主要方法:
- 10名SSc患者心脏性休克和急性心室功能障碍的观察研究 (2010-2023年).
- 分析临床,实验室,成像 (包括心脏MRI) 和病理学数据.
- 六个月的结果评估.
主要成果:
- 该队列主要是女性 (90%),患有扩散的皮肤SSc (70%) 和显著的血液动力学不稳定性.
- 所有患者都有心周溢出,心脏MRI显示晚期加多增强,延长T2放松时间,减少左心室喷射率 (LVEF).
- 炎症细胞透的心肌炎在病理上得到证实;住院死亡率为60%,幸存者在六个月内只有有限的LVEF恢复.
结论:

Imbalances in Cardiac Output
1.2K
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...

Pathophysiology of Heart Failure
1.4K
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...

Cardiovascular System Abnormal Findings II: Auscultation
81
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.
