まとめ
中部領域のプロアトリアルナトリウレチンペプチド (MR-proANP) レベルが上昇すると,心臓転換後の心房細動の再発が独立して予測されます. この発見は1年以内にAF再発のリスクが高い患者を特定するのに役立ちます.
科学分野:
- 心臓病科
- バイオマーカー
- 電気生理学
背景:
- 電気心臓転換後の心房細動 (AF) の再発は一般的です.
- シヌスリズムを維持するための予測マーカーが必要です.
- 脳ナトリウレチンペプチド (NT-proBNP) のN末端プロホルモンおよび他のバイオマーカーが調査されました.
研究 の 目的:
- MR-proANP,溶解性ST2 (sST2),およびB型ナトリウレチンペプチド (BNP) が,持続性AFの電気カルディオバーションの成功から1年後にシヌスリズムを維持するための予測能力を評価する.
- AFの再発予測のための新しいバイオマーカーを特定する.
主な方法:
- 展望的で多中心の観察研究です
- 継続的なAFを患った患者も含まれていた.
- 循環前,外周静脈血で測定されたMR-proANP,sST2,およびBNP.
- 主要エンドポイント:ECGまたはHolterモニタリングによって定義された12ヶ月以内にAFの再発.
主要な成果:
- 61人の患者が含まれ,その83. 6%が心臓転換後の鼻腔リズムを達成した.
- MR- proANP濃度は,再発性AF患者 (314. 45 pmol/ L) と,再発性AF患者 (214. 50 pmol/ L) と比べて有意に高かった (p < 0. 01).
- 311.5 pmol/ LのMR-proANPの値がAF再発を最もよく予測する (HR 4. 74). sST2とBNPは予測値を示さなかった.
結論:
- 高濃度のMR-proANPは,心臓転換後1年以内にAFの再発を独立して予測する.
- MR- proANPは,AF再発のリスクの高い患者を特定するための貴重なバイオマーカーとして機能する.
- より大きな研究でさらなる検証が必要である.

Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
160
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Pulse rhythm
925
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Disturbances in Heart Rhythm
1.2K
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 heart...
