概括
在急性心肌梗塞 (AMI) 患者的非罪祸首血管中,血管学衍生的分流储量 (Angio-FFR) 预测了结果,而血管IMR则没有. 这表明心脏上封闭, 而不是微循环问题, 驱动预后.
科学领域:
- 心脏病学
- 干预心脏病学
- 血管生理学
背景情况:
- 在急性心肌梗塞 (AMI) 中管理非罪祸首的血管是具有挑战性的.
- 最近的血管学评估可能有助于NCV管理.
- 这些评估在NCV中的预测值需要澄清.
研究的目的:
- 在AMI患者的NCV中测量血管造影衍生的分流储量 (Angio-FFR) 和血管造影衍生的微循环阻力指数 (Angio-IMR).
- 在NCV中探索Angio-FFR和Angio-IMR的预后值.
- 在NCV中测量Angio-IMR与Angio-FFR的必要性.
主要方法:
- 对503名患有多血管性心脏病 (MVD) 的患者进行了回顾性队列研究.
- 在40-80%视觉狭窄的NCV测量Angio-FFR和Angio-IMR.
- 主要终点:在2年的随访中面向容器的复合终点 (VOCE).
主要成果:
- 具有Angio-FFR≤0. 8的NCV显示出显著更高的VOCE率 (27%对12. 6%,P<0. 001).
- 基于值的VOCE没有显著差异 (15. 15%与11. 04%,P=0. 383).
- 血管-FFR是VOCE的独立预测因子 (HR: 1. 70),而血管-IMR则不是 (HR: 0. 88).
结论:
- 在AMI患者中NCV的预后与Angio-FFR相关,而不是Angio-IMR.
- 皮心血管封闭,而不是微循环功能障碍,似乎导致NCV的不良预后.
- 与Angio-FFR相比,测量Angio-IMR对于AMI中NCV的管理具有有限的必要性和临床价值.

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...

25
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

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,...

45
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...

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...
