概括
急性心肌梗塞 (AMI) 患者的高血糖预测死亡. 入院时的低血糖显示出非显著的趋势,入院后的低血糖与死亡率无关,这表明它可能不会直接导致不良后果.
科学领域:
- 心脏病学 心脏病学
- 内分泌学 在内分泌学.
- 临界护理医学 临界护理医学
背景情况:
- 过高血糖是急性心肌梗塞 (AMI) 患者死亡的一个已知的预测因素.
- 低血糖在AMI的预后意义仍然存在争议,需要进一步调查.
研究的目的:
- 在一大群AMI患者中评估低血糖和高血糖的预后意义.
- 为了比较30天死亡率的入院和入院后葡萄糖水平的预测值.
主要方法:
- 从两项大型葡萄糖-胰岛素-治疗试验中对30536名AMI患者进行了临时分析.
- 多变量考克斯模型用于评估低血糖 (<或=70毫克/分升) 和高血糖 (>或=140毫克/分升) 与正常血糖的预后值.
- 用替代低血糖定义和分组 (糖尿病,胰岛素治疗) 重复分析.
主要成果:
- 住院和住院后的高血糖 (>=140 mg/dL) 均显著预测了30天死亡率的增加 (aHR分别为1.43和1.47).
- 接受治疗时的低血糖 (<=70 mg/dL) 并没有预后 (aHR 1.16),接受治疗后的低血糖 (aHR 0.96) 也没有.
- 这些发现在不同的低血糖定义和糖尿病患者中保持一致.
结论:
- 住院和住院后的高血糖是AMI患者30天死亡率的显著预测因素.
- 低血糖,特别是在入院后,似乎不是AMI中不良结果的直接调解者.
- 临床重点应继续放在AMI患者的高血糖管理上.

Hypoglycemia and Glucagon
1.3K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
954
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...

Acute Coronary Syndrome III: Diagnostic Studies
500
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...

Complications of Diabetes Mellitus
43
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...

Hypoglycemia
34
Hypoglycemia is a blood glucose level below 70 mg/dL. It commonly occurs in individuals using insulin or insulin-secreting drugs, but may also arise in non-diabetic conditions. People with type 1 diabetes are at the highest risk because they depend on exogenous insulin. People with type 2 diabetes are also at risk, especially when treated with insulin or medications such as sulfonylureas, which increase insulin release regardless of blood glucose levels. It develops when insulin levels exceed...

Hyperglycemia
34
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose...
