Despite advances in both knowledge and technology, coronary heart disease is the most common cause of death worldwide. Currently, substantial expenditure in the health service is directed towards restoring blood flow in patients with acute myocardial infarction (AMI) in order to limit myocardial injury. Whilst this has substantially reduced early mortality, nevertheless the associated myocardial injury frequently leads to the development of heart failure, that may develop either soon or a long time after the triggering event. Whilst prompt reperfusion is a prerequisite to limit myocardial injury, paradoxically the process of reperfusion itself causes myocardial injury - a phenomenon called ischaemia-reperfusion injury (IRI). In addition to prompt reperfusion (usually by percutaneous coronary intervention (PCI)) there is an urgent need for effective adjunctive therapies that limit myocardial injury due to IRI.
Nitrite is an important physiological mediator under hypoxic and acidic conditions. In experimental studies, it has been shown that nitrite protects against myocardial ischaemia reperfusion injury. In man, we have demonstrated that nitrite improves cardiac function. However, despite these promising findings, the mechanisms by which nitrite-mediates protection remains to be elucidated. We will extend this work to investigate the mechanisms by which nitrite protects the heart against reperfusion injury. This study will use a broad range of techniques, such as Langendorff model, isolated cardiomyocytes, and various molecular techniques.
