概括
快速纵向缩短指标,是一种简单的替代功能跟踪应变,有效预测心血管结果. 这些测量显示了心力衰竭和死亡率的可比预后值.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 生物标志物 生物标志物
背景情况:
- 心脏磁共振 (CMR) 成像为心脏功能障碍提供了有价值的早期生物标志物.
- 心肌应变指标,包括特征追踪 (FT) 应变,对于评估左心室 (LV) 变形至关重要.
- 为了更广泛的临床应用,需要简化,独立于软件的措施.
研究的目的:
- 为了建立测量快速纵向缩短 (RLS) 的最佳实践,简化了LV变形度量.
- 评估RLS和FT菌株之间的相关性和一致性.
- 为了比较RLS和FT菌株对心血管结果的预后值.
主要方法:
- 利用了来自45844名参与者的英国生物库数据 (平均年龄65岁,52%为女性).
- 导出了两个RLS指标 (长轴缩短,LS;心房结缩短,AVJS) 和三个FT应变指标 (GLS,GCS,GRS).
- 使用皮尔森相关性和布兰德-阿尔特曼图表评估相关性/一致性;通过4.4年的考克斯回归评估预后值,以混因子进行调整.
主要成果:
- LS和AVJS显示了与全球纵向菌株 (GLS) 的中度相关性和一致性.
- LS,AVJS和GLS独立地与发生的心血管结果 (心力衰竭,心肌梗塞,中风,心血管死亡) 相关.
- RLS指标的预测值与发生性心力衰竭的FT菌株的预测值相当 (HRs在0.78-0.79之间).
结论:
- 快速纵向缩短指标是心血管结果的重要预测指标.
- RLS提供了一个简单的,潜在的软件和供应商独立的替代品,用于评估心脏功能和预后.

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,...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
