Meta-Analysis Zheng et al. (Frontiers in Cardiovascular Medicine, 2023) 進行了一個專門針對 maintenance dialysis patients 的 meta-analysis [7],納入 8 項研究共 1,685 名病人:
Long-term all-cause mortality:Revascularization 顯著低於 medical therapy alone(RR 0.73, 95% CI 0.63-0.84)
Long-term cardiac mortality:Revascularization 同樣更低(RR 0.55, 95% CI 0.40-0.76)
Bleeding events:兩組無顯著差異(RR 0.93, 95% CI 0.65-1.32)
Figure 1. Revascularization vs. medical therapy 在維持性透析病人中的 meta-analysis。(A) Long-term all-cause mortality:RR 0.73 (95% CI 0.63-0.84), favoring revascularization;(B) Long-term cardiac mortality:RR 0.55 (95% CI 0.40-0.76);(C) Bleeding events:無顯著差異。 (Source: Zheng L et al., Front Cardiovasc Med 2023;10:1143895)
然而,subgroup analysis 揭示了重要的異質性:
PCI vs. MT:PCI 顯著降低 all-cause mortality(RR 0.72, 95% CI 0.62-0.84)
CABG vs. MT:CABG 與 MT 無顯著差異(RR 0.91, 95% CI 0.57-1.46),且 heterogeneity 高 (I² = 68%)
Figure 2. Subgroup analysis:(A) PCI vs. MT 在透析病人中顯著降低 long-term all-cause mortality(RR 0.72, 95% CI 0.62-0.84);(B) CABG vs. MT 則無顯著差異(RR 0.91, 95% CI 0.57-1.46),且 heterogeneity 高。 (Source: Zheng L et al., Front Cardiovasc Med 2023;10:1143895)
