- 包括8个RCT与379名参与者;评估偏差风险和执行子组分析.
主要成果:
- 兰诺在8-12周内显著增加了冠状动脉流量储备 (CFR) (SMD=1.16,P=0.002).
- 观察到的全球心肌输液储备指数 (MPRI) (WMD=0.18,P=0.002) 和中下心脏MPRI (WMD=0.10,P=0.02) 的改善.
- 兰诺素改善了身体功能,心痛稳定性和生活质量得分 (SAQ).
结论:
- 兰洛在非阻塞性冠状动脉疾病中增强冠状动脉微血管功能方面表现出有效性.
- 在心肌输液和患者报告的结果 (SAQ分数) 中发现了改善.
- 建议进行较大的长期RCT以进一步验证和全面理解.

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
