概括
在心肌梗塞 (MI) 后的患者中,突然心脏死亡 (SCD) 的危险因素包括年龄较大,排气率降低和来自东南亚. 识别这些患者可以指导植入式心脏转换器-除器 (ICD) 用于预防.
科学领域:
- 心脏病学 心脏病学
- 公共卫生 公共卫生
背景情况:
- 植入式心脏转换器-除器 (ICD) 在心肌梗塞 (MI) 后的患者中未被充分用于预防心脏突然死亡 (SCD).
- 了解区域风险因素对于优化ICD采用和患者选择至关重要.
研究的目的:
- 确定后心脏病发作患者全因和心血管死亡的危险因素.
- 在使用ICD较少的人群中为SCD预防策略提供信息.
主要方法:
- 从改善突然心脏骤停 (SCA) 桥梁试验中对心脏骤停后患者的死亡风险因素的分析.
- 多变量建模以评估所有原因和心血管死亡率的预测因素.
主要成果:
- 整体1年死亡率为5.9% (所有原因) 和3.4% (心血管),其中76.5%的心脏死亡是由于SCD.
- 全因死亡率的显著风险因素包括年龄增加,左心室喷射率 (LVEF) 减少,从心脏病发作到入院的时间长,女性性别,来自东南亚 (SEA),以及冠状动脉疾病.
- 增加年龄,降低LVEF和来自南亚的身份是心血管死亡的重要风险因素.
结论:
- 特定的患者特征预测心血管死亡率后MI.
- 患有已识别的风险因素的患者需要向电生理学家推SCD风险分层.
- 及时干预,包括潜在的ICD植入,可以减少可预防的死亡.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
137
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Ischemic Heart Disease: Overview
1.3K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Imbalances in Cardiac Output
1.4K
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...
