Ischaemic heart disease (IHD) is the leading cause of morbidity and mortality worldwide. While timely reperfusion of acutely ischaemic myocardium is essential for myocardial salvage, it leads to a unique type of injury known as 'myocardial ischaemia/reperfusion (I/R) injury'. Growing evidence suggests that a defect in myocardial Ca(2+) transport system with cytosolic Ca(2+) overload is a major contributor to myocardial I/R injury. Progress in molecular genetics and medicine in past years has clearly demonstrated that modulation of Ca(2+) handling pathways in IHD could be cardioprotective. The potential benefits of these strategies in limiting I/R injury are vast, and the time is right for challenging in vivo systemic work both at pre-clinical and clinical levels.
缺血性心脏病(IHD)是全球发病率和死亡率的主要原因。虽然急性缺血心肌的及时再灌注对于心肌挽救至关重要,但它会导致一种称为“心肌缺血/再灌注(I / R)损伤”的独特损伤类型。越来越多的证据表明,细胞溶质 Ca(2+)超载导致心肌 Ca(2+)转运系统缺陷是心肌 I / R 损伤的主要原因。过去几年分子遗传学和医学的进展清楚地表明,调节 IHD 中的 Ca(2+)处理途径可能具有心脏保护作用。这些策略在限制 I / R 损伤方面的潜在益处是巨大的,现在正是在临床前和临床水平上挑战体内全身性工作的合适时机。
