Brief summary
Clonal haematopoiesis of indeterminant potential (CHIP) is defined a genetic variation that leads to expansion of certain blood cells, particularly those with an immune function. CHIP is increasingly common beyond the age of 65 and associated with an increased risk of heart attack. The purpose of this study is to find out more about inflammatory processes after heart attack for CHIP positive patients compared to CHIP negative patients. We will screen for inflammatory markers and other molecular information in blood samples from people with and without CHIP who have had a recent heart attack.
Interventions
Consenting participants who have had a myocardial infarction will undergo the collection of clinical data sourced from the medical record, and blood samples will also be taken. The blood samples will be used for analysing lipids, inflammatory markers and other markers of vascular injury. The sample will also undergo genetic analysis for somatic gene mutations so that participants can be classified as having or not having clonal haematopoiesis of indeterminant potential. An additional blood sample will be stored for future biomedical research in participants who content to this. Participants may be followed for additional samples or medical records may be accessed within a 5 year period. Up to two additional blood samples may be taken at any time within a 2 year period, post-myocardial infarction.
