概括
左心室全局工作效率 (LVGWE) 有效预测ST段升高心肌梗塞 (STEMI) 的肥胖患者的不良心血管事件. 较高的LVGWE (≥79%) 表明该人群中主要不良心血管事件 (MACE) 的风险较低.
科学领域:
- 心脏病学 心脏病学
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
- 心血管研究研究心血管研究
背景情况:
- 在ST段升高心肌梗塞 (STEMI) 患者中,肥胖很普遍,使预后复杂化.
- 传统的心声回声指标可能不足以对肥胖STEMI患者的风险分层进行分层.
- 左心室心肌工作 (LVMW) 是心肌性能的新兴负载调整标志物.
研究的目的:
- 评估LVMW在患有STEMI的肥胖患者的预后意义.
- 为了确定LVMW参数是否可以提高风险预测超越传统方法.
主要方法:
- 143名STEMI患者被前性招募并根据肥胖症 (BMI ≥30 kg/m2) 分类.
- 心声 LVMW 参数,包括左心室整体工作效率 (LVGWE),在入院后 72 小时内进行测量.
- 随访患者主要的不良心血管事件 (MACE),包括心血管死亡,心律失常和心力衰竭住院治疗.
主要成果:
- 在平均13个月的时间里,30名患者 (21%) 经历了MACE.
- 在肥胖患者中,LVGWE是MACE最强的预测因子 (AUC=0.736,p=0.009),确定了79%的值.
- 肥胖患者的LVGWE≥79%具有显著较低的MACE率 (逻辑排名p=0.006) 和降低的风险 (HR=5.59,p=0.019).
结论:
- 在STEMI患者中,LVGWE提供了显著的预后价值,特别是在肥胖子组中.
- LVGWE可以增强风险分层,并指导肥胖STEMI患者的临床管理.
- 将心肌工作指数整合到常规心声回声学中可能会改善高风险心血管人群的结果.

Imbalances in Cardiac Output
1.6K
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 send...

Cardiomyopathy III: Hypertrophic Cardiomyopathy
65
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...

Acute Coronary Syndrome III: Diagnostic Studies
26
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...

Pathophysiology of Heart Failure
1.9K
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...
