概括
心肌工作指数与传统指标不同,可以预测肥胖患者的死亡率. 较低的心肌工作值表明死亡风险明显更高,即使在看似低风险的人群中也是如此.
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.
- 公共卫生 公共卫生
背景情况:
- 肥胖和超重是心血管疾病的重要危险因素.
- 传统的心声回声可能会错过肥胖个体的亚临床缩功能障碍.
- 心肌工作 (MW) 分析为评估左心室 (LV) 功能提供了更敏感的方法.
研究的目的:
- 评估肌肉心脏工作指数的预后能力在社区基队列中,跨越肥胖的不同阶段.
- 确定MW指标是否可以识别超重和肥胖个体的传统心声测量错过的心血管风险.
主要方法:
- 从人口查计划中对1330个人的回顾性分析,按BMI分类为正常体重,超重和肥胖群体.
- 2D心声回声被用于测量LV喷射分数 (EF),LV全球纵向应变 (GLS),全球MW指数 (GWI),全球浪费工作 (GWW) 和全球MW效率 (GWE).
- 所有原因的死亡率被追踪在11年的中位随访期作为主要终点.
主要成果:
- 左心室喷射分数 (LVEF) 并没有预测结果.
- 全球工作指数 (GWI),全球浪费工作 (GWW),全球工作效率 (GWE) 和全球纵向应变 (GLS) 是整体队列中死亡率的不可变预测因素.
- 在超重个体中,GLS,GWE和GWW预测死亡率. 在肥胖组中,只有GWI是显著的预测因素.
- 超重和肥胖以及GWI低于1292 mmHg%的个体有两倍以上的全因死亡风险.
结论:
- 心肌工作指标是不同程度肥胖的个体长期结果的重要预测指标.
- 传统的心声回声测量可能低估了超重和肥胖人口的心血管风险.
- 心肌工作分析为这些个体的风险分层提供了更敏感的工具.

Pathophysiology of Cardiac Performance
805
Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...

Acute Coronary Syndrome III: Diagnostic Studies
23
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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy
48
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...
