Studies that accurately identify myocardial infarction (MI) and stroke within populations would provide valuable epidemiological information as well as data on vascular disease prevention. We performed a pilot study to assess the feasibility of adding MI surveillance to an ongoing population-based stroke surveillance study, the Brain Attack Surveillance in Corpus Christi (BASIC) Project. We also tested two screening methods for MI ascertainment: discharge International Classification of Diseases, Ninth Revision (ICD-9) codes and cardiac biomarker screening. This pilot study suggests that the addition of MI surveillance to community-based stroke surveillance studies is feasible. Screening for abnormal cardiac biomarkers to identify potential MI cases may be more accurate and efficient than using ICD-9 codes.
