MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We know from previous studies that patients with unrecognized myocardial infarcts have worse prognosis than people without infarcts.

It was currently unknown in how many patients presenting with a first acute myocardial infarction had previous unrecognized MI, and if so, if this is still a prognostic marker on long term follow-up.

In this paper we studied 405 patients from 2 academic hospitals in the Netherlands, with an average follow-up duration of 6.8 years. We found that silent MI was present in 8.2% of patients presenting with first acute MI, and that silent MI is a strong and independent predictor for adverse long-term clinical outcome such as death (HR 3.69) or the composite end point of death, reinfarction, ischemic stroke, or CABG (HR 3.05). Additionally, it appears that ECG is of limited value to detect silent MI, since our study did not reveal an association with long-term clinical outcome.
