Summary

Non-cardiac acute and chronic inflammatory conditions are associated with high risk of acute myocardial infarction.

Specifically, there are reports of high prevalence of AMI and cardiac death in chronic conditions such as Rheumatoid arthritis, chronic gum disease, psoriasis and Chronic airway disease. Furthermore, there are intriguing temporal links between acute non-cardiac conditions, including fractured neck of femur and admission for chest infection in the elderly and subsequent risk of AMI within the next few weeks. Finally, a more recent association has been reported between COVID vaccination and acute thrombotic events.

In Summary, a link between acute non-cardiac inflammatory conditions and subsequent AMI in a near term envelope is established, but unexplained, and circumstantial evidence so far suggests a possible mechanism in terms of dynamic alteration in platelet reactivity. It is this concept we wish to explore further in the proposed set of experiments.

Our experiments may provide some insight into a potential mechanism of such an association, which could have implications for future tailored therapeutic interventions.

We will recruit 5 groups of patients, consistent with the data produced previously and the literature regarding disease models of non-cardiac inflammations. Aiming to recruit 20 patients per group with 100 candidates in total. Groups including:

1. Fracture neck of femur.
2. Patients \>70 years age admitted with chest infection.
3. Healthy volunteers receiving fourth COVID booster vaccine.
4. Patients admitted with AMI within 6 weeks of (fractured neck of femur, chest infection Rheumatoid arthritis flare up, exacerbation of psoriasis and exacerbation of inflammatory bowel disease).
5. AMI secondary to stent thrombosis.

Study will be undertaken within the Cardiothoracic unit at University Hospital Southampton, the sponsor will be UHS Research and Development Department, UHS.
