Key result
ICD codes for myocardial infarction in the Finnish Hospital Discharge and Causes of Death Registers demonstrated an overall sensitivity of 83% and a positive predictive value of 90%.

Supports Finnish register use for CHD epidemiology; leaves open generalizability to other systems.
Observational
Are the Finnish Hospital Discharge Register and Causes of Death Register valid indicators for hard CHD events compared to the FINMONICA/FINAMI register?
Effect estimate: PPV 90%
Diagnoses of fatal and non-fatal CHD events in the Finnish HDR and Causes of Death register are reasonably valid indicators for hard CHD events, supporting their use in epidemiological studies.
Pajunen et al. (2005) conducted an observational in Coronary heart disease. ICD codes in Finnish HDR and CDR vs. FINMONICA/FINAMI register was evaluated on Sensitivity of ICD codes for myocardial infarction (PPV 90%). ICD codes for myocardial infarction in the Finnish Hospital Discharge and Causes of Death Registers demonstrated an overall sensitivity of 83% and a positive predictive value of 90%.
