概括
切换心脏热素I测定为热素T增加了心肌损伤的识别和住院. 然而,这种变化并没有改善疑似急性冠状动脉综合征患者1年的心血管结果.
科学领域:
- 心脏病学 心脏病学
- 临床诊断 临床诊断 临床诊断
- 生物标志物检测试验 生物标志物检测
背景情况:
- 高灵敏度的心脏托波T (hs-cTnT) 和I (hs-cTnI) 测定对于诊断心肌梗塞至关重要.
- 在hs-cTnI和hs-cTnT测定之间切换的临床影响仍然不清楚.
研究的目的:
- 评估从hs-cTnI过渡到hs-cTnT测定对患者护理和结果的影响.
- 评估疑似急性冠状动脉综合征 (ACS) 患者的心肌损伤检测,检测频率和临床结果的变化.
主要方法:
- 未来的,多中心的,中断的时间序列研究.
- 从2020年10月到2022年10月,涉及3个急性护理中心,并于2021年10月从hs-cTnI切换到hs-cTnT.
- 主要结局是住院治疗;次要结局包括心肌损伤的识别和1年的心血管事件.
主要成果:
- 过渡到hs-cTnT与已确定的心肌损伤 (21%对38%) 和住院病例 (OR,2.24) 的显著增加有关.
- 转换后,连续激素检测增加了六倍 (OR,6.03).
- 在1年内心肌梗塞,心力衰竭或心血管死亡的综合结果中没有显著差异 (OR,0.83).
结论:
- 过渡到hs-cTnT测定增加了心肌损伤的检测和住院.
- 尽管增加了检测和入院,但转换为hs-cTnT并没有证明改善1年的心血管结果.
- 需要进一步的研究来了解临床影响和优化ACS管理策略.

190
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...

690
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

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...

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
