概括
使用14天监测器对老年人进行心房动 (AF) 查并没有减少中风住院的情况. 这项研究发现,查和通常护理组之间的中风或出血事件没有显著差异.
科学领域:
- 心脏病学 心脏病学
- 预防医学 预防医学
- 临床试验 临床试验
背景情况:
- 未诊断的心房动 (AF) 显著增加缺血性中风风险.
- 口服抗凝药有效预防AF相关的中风.
- 之前的试验显示,随着更长的查,AF识别增加,但中风减少仍然没有得到证实.
研究的目的:
- 为了评估是否使用14天心电图监测器对70岁以上的个人进行AF查,可以减少中风.
- 确定AF查与口服抗凝药决策相结合是否提供与常规护理相比的净临床益处.
主要方法:
- 该GUARD-AF试验是一项前性,随机对照性研究.
- 参与者 (≥70岁) 被随机分配到14天的心电图监测或常规护理.
- 主要结局是中风住院和出血;使用治疗意图分析.
主要成果:
- 该研究招募了11,905名参与者,随访时间中位数为15.3个月.
- 在查组中,中风风险为0.7%,在常规护理组中为0.6% (HR:1.10).
- 出血风险为1.0%与1.1% (HR:0.87);在查组中,AF诊断率更高 (5%与3.3%).
结论:

Imaging Studies for Cardiovascular System I:Echocardiography
303
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Antiarrhythmic Drugs: Class II Agents as β-Adrenergic Blockers
719
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...

Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers
798
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...
