まとめ
非緊急の心臓手術,特にトランスキャテーター心弁手術の延期は,心不全 (CHF) とより悪い臨床結果のリスクを大幅に高めます. これらの介入の優先順位は 副作用を回避し 患者の予後を改善するために重要です
科学分野:
- 心臓病科
- 介入心臓科
- 心不全 の 治療
背景:
- 非緊急の心臓介入の延期は,より悪い臨床結果と関連しています.
- 手術が遅れた患者は,心臓不全 (CHF) が発症する可能性があります.
- 待ち時間中にCHFの進行を予測する要因を特定することが不可欠です.
研究 の 目的:
- 心臓介入の長期待ち時間における臨床的に進行するCHFの予測要因を特定する.
- CHFが介入のタイミングと結果に与える影響を評価する.
- 延期された介入後の結果に対するベースライン予測者の効果を評価する.
主な方法:
- COVID-19のロックダウン (2020年3月~4月) の間,緊急でない心臓の介入を延期した178人の患者群を分析した.
- 臨床的に進行するCHF (NT-proBNP > 900 pg/ ml,呼吸不全の悪化,心不全の入院,またはLVEFの低下) の予測要因が二次ロジスティック回帰で特定されました.
- 結果は2019年に治療を受けた対照群 (n=214) と比較された.
主要な成果:
- 治療が延期された患者の50%は,介入の日にCHFの兆候を示した.
- トランスキャテーターによる心臓弁の介入は,CHFの進行を予測する唯一の独立した要因であった (OR34. 6).
- ミトラル/トリコスピッド端から端までの修復 (M/T-TEER) は,トランスキャテータ大動脈弁置換 (TAVR) よりもリスクが高い.
- CHFの患者は36ヶ月以内に病院入院または死亡率 (57. 3% vs 14. 0%) が著しく高かった.
- 延期されたトランスキャセータ心弁介入,特にM/T-TEERは,より悪い結果をもたらしました.
結論:
- トランスキャテーター心弁の介入,TAVR,特にM/ T- TEERの延期は,進行性CHFと有害な臨床結果のリスクを大幅に増加させます.
- リスクを軽減し,患者の予後を改善するために,これらの手順を優先し,延期を避けるべきです.

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

Imbalances in Cardiac Output
1.5K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
