概括
在心房动 (AF) 患者中保持60-80bpm的心率与较少的心脏重塑有关. 较高的速率 (每分钟100次以上) 与更严重的重塑相关,影响心脏结构和功能.
科学领域:
- 心脏病学 心脏病学
- 心脏电生理学 心脏电生理学
- 内部医学 内部医学
背景情况:
- 心房动 (AF) 是一种常见的心律失常,需要心室节拍控制.
- 最佳心室率目标及其对AF心脏重塑的影响尚未完全理解.
- 现有的研究缺乏关于心率控制水平的变化与AF患者心脏重塑之间的关系的明确性.
研究的目的:
- 调查不同心室节拍控制水平与早期持久性心房的患者心脏重塑之间的关联.
- 为了确定特定的心率范围是否会影响AF心脏结构变化的进展.
- 提供关于最佳心率管理策略的见解,以减轻AF中的心脏重塑.
主要方法:
- 一项双中心前性队列研究招募了764名新诊断的持久性AF和快速心室率的患者.
- 根据24小时的霍尔特监测,患者被分为四组:<60 bpm,60-80 bpm,80-100 bpm和≥100 bpm.
- 心脏重塑通过追踪左心脏直径 (LAD),左心室终端-透缩直径 (LVEDD),左心室喷射率 (LVEF) 和一年多的 mitra regurgitation 严重程度来评估.
主要成果:
- 一年后,在两组之间观察到心脏重塑的显著差异 (p < 0.001).
- 增加心脏重塑的趋势是第二组 (<60-80 bpm) <第一组 (<60 bpm) <第三组 (80-100 bpm) <第四组 (≥100 bpm).
- 回归分析表明,BMI影响LAD变化,丁素影响LVEF,某些药物/疾病 (diltiazem,比索普罗罗罗尔,高血压,CAD,吸烟,糖尿病,COPD) 与恶化腹有关.
结论:
- 不同水平的心室节拍控制显著影响心脏重塑在早期持久性AF.
- 保持60-80bpm之间的平均心室率可能与较少的心脏重塑有关.
- 平均心率≥100 bpm似乎与AF患者最严重的心脏重塑有关.

Disturbances in Heart Rhythm
892
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...

Mechanism of Cardiac Arrhythmias
885
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
378
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Pathophysiology of Heart Failure
1.5K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
