まとめ
心房細動 (AF) は,心筋梗塞 (MI) の患者の死亡リスクを増大させる. このリスクは,新規発症したAFでも持続し,MIの際に深刻な合併症であることを示す.
科学分野:
- 心臓病学 心臓病学
- クリニカル・メディシン 臨床医学

背景:
- 動脈動 (AF) は,心筋梗塞 (MI) 患者において一般的である.
- 臨床医は,急性心筋梗塞 (MI) 時のAFの影響を過小評価することが多い.
- MIにおけるAFの予後的な影響と死亡リスクについて議論されています.
研究 の 目的:
- MI患者におけるAFに関連した死亡リスクを体系的にレビューし,メタ分析する.
- AFのタイミングが死亡リスクに与える影響を調査する.
- MI中のAFの予後的有意性を定量化するために.
主な方法:
- 電子データベースに関する包括的な文献検索 (1970-2010年).
- 278,854人の被験者を含む43件の研究が含まれています.
- 調整されたオッズ比率をプールするために使用されたランダム効果モデル; I2統計を使用して評価された異質性.
主要な成果:
- 心房細動 (AF) は,心筋梗塞 (MI) 患者の死亡リスクの1.46倍増加と関連していた (95%CI,1.35-1.58).
- この増加したリスクは,新規発症したAF (OR 1.37) と以前のAF (OR 1.28) に一貫していました.
- 感受性分析は,新しいAFが独立してMI後の死亡リスクの増加を予測することを確認しました.
結論:
- 心房細動は,心筋梗塞患者の死亡リスクを大幅に増加させます.
- リスク要因を調整した後でも,MI中の新規発症したAFは,より高い死亡率と関連しています.
- AFは,良性発見ではなく,心筋梗塞中の重要な出来事として認識されるべきです.

Mitochondria
19.4K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Animal Mitochondrial Genetics
8.9K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Mutations
42.6K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

Electron Transport Chain: Complex I and II
18.3K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.

Mitochondrial Membranes
16.5K
A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...
