概括
德克萨米他通过降低炎症,在动冠状动脉旁路移植 (CABG) 患者中降低了术后心律失常. 在非 CABG 程序中没有观察到这种效应,尽管甲松确实降低了这两组的炎症标志物.
科学领域:
- 心脏病学 心脏病学
- 药理学 药理学 是一个学科.
- 炎症研究 炎症研究
背景情况:
- 冠状动脉旁路移植 (CABG) 与术后心律失常的显著风险有关.
- 炎症在这些心律失常的发展中起着关键作用.
- 在CABG期间预防心律失常的德克萨米松的疗效尚未完全理解,特别是在内 (ONCAB) 和外 (OPCAB) 程序之间进行区分.
研究的目的:
- 评估德克萨梅他在治疗ONCAB和OPCAB的患者中减少术后心律不整的疗效.
- 在CABG手术的背景下,研究德克萨米他对炎症标志物 (IL-6,CRP,前素) 的影响.
- 探索系统性炎症和CABG后心律失常的发生之间的关系.
主要方法:
- 一个单中心随机对照试验,涉及120名接受ONCAB或OPCAB治疗的患者.
- 患者接受了德克萨米他或安慰剂.
- 术后心律不整的病例每小时监测一次,直到出院. 在所有患者中测量了炎症标志物.
主要成果:
- 总体而言,24.2%的患者出现心律失常.
- 德克萨米在ONCAB组显著降低了心律失常 (p = 0.02),但在OPCAB组没有 (p = 0.347).
- 在ONCAB和OPCAB患者中,德克萨米他的使用导致IL-6,CRP和前素的显著降低 (p = 0.001).
- 患有心律失常的患者表现出更高水平的IL-6,CRP,和prokalcitonin.
结论:
- 德克萨米在减少ONCAB后的术后心律不整方面是有效的,可能是通过调节系统性炎症.
- 虽然德克萨米他在ONCAB和OPCAB患者中减少了炎症标志物,但其抗心律不整的作用是特定于ONCAB程序的.
- 用德克萨米他等药物向炎症可能是一个可行的策略,用于预防特定心脏手术环境中的心律失常.

710
Adrenergic stimulation generally impacts cardiac rate and rhythm. Specifically, stimulation of the β-adrenoceptors triggers an increase in intracellular calcium ion influx and pacemaker currents, which may cause arrhythmias. Catecholamines like adrenaline also demonstrate β2-adrenoceptor-mediated hypokalemia, impacting cardiac action potential and disrupting the normal cardiac rhythm. Class II antiarrhythmic drugs are β-adrenoceptor antagonists or β-blockers, which...

915
Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of...

01:20Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers
783
Class IV antiarrhythmic drugs, such as verapamil and diltiazem, block calcium channels. They primarily affect the heart, slowing the conduction in calcium-dependent tissues like the SA and AV nodes. These drugs manage reentrant supraventricular tachycardia (SVT) and reduce ventricular rate in atrial flutter/fibrillation.
Verapamil, a calcium channel blocker, inhibits calcium movement across myocardial cell membranes and vascular smooth muscle. This results in the dilation of coronary and...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...
