Heart attacks are a leading worldwide cause of death. Tens of millions of people each year die as a result of coronary disease. Although many scores have been developed to assist in short-term risk
stratification in the immediate aftermath of an acute coronary syndrome, coronary heart disease remains a major cause of mortality after the acute period of stabilization. Approximately 20% of patients experiencing an acute myocardial infarction die within one year, with over half the first-year mortality occurring greater than thirty days after presentation.
Assessment of longer-term survival after stabilization for an acute myocardial infarction has received much less attention than immediate risk stratification. We developed the Seattle Post
Myocardial Infarction Model (SPIM) to provide a well-calibrated and highly discriminative tool that could accurately predict survival six months, one and two years after a myocardial infarction
in patients with evidence of left ventricular dysfunction.
The model was developed by Drs. Wayne Levy and Eric Ketchum and co-authors as shown in the publication.
The Java applet to calculate the score was designed by Drs. Linker, Ketchum, and Levy and programmed by Dr. David Linker.
