<p class="abstract"><strong>Abstract</strong></p> <p class="abstract"><strong>&nbsp;&nbsp; BACKGROUND:</strong> This study aimed to investigate 28-day case fatality rate due to acute myocardial infarction (MI) in Isfahan using a standardized surveillance system.</p> <p class="abstract"><strong>&nbsp;&nbsp; METHODS:</strong> A prospective longitudinal study was performed on hospitalized myocardial infarction patients in Isfahan, Iran from 2000 to 2004. All hospitalizations due to myocardial infarction (MI) events were recorded via a system adopted from &ldquo;World Health Organization Monitoring Trends and Determinants in Cardiovascular Disease&rdquo; (MONICA) project, with ignoring MONICA age limitation. Patients were followed and their families enquired about their patients survival status at 28^th day with phone calls and if not available at home visits.</p> <p class="abstract"><strong>&nbsp;&nbsp; RESULTS:</strong><strong> </strong>Age-adjusted hospital admission rate showed an increase during the study period, rising from 131.67 to 209.27 per 100000, but slowed toward the end of the study. Patients&rsquo; mean age was 62.35&plusmn;12.64, with one third of events documented among female patients. Young patients (&lt; 45 years old) comprised 8.6% of hospitalizations which remained nearly constant through the study. The corresponding figure was about 28% for patients aged less than 55 years. The 28-day case fatality rate was 23.1% for women and 13.2% for men. For individuals aged <br /> 35-64 years, the fatality rate was 13.0% for women and 7.7% for men.<strong>&nbsp;</strong></p> <p class="abstract"><strong>&nbsp;&nbsp; </strong><strong>CONCLUSION:</strong> This study showed an increase in myocardial infarction hospital admission rate in Isfahan but the rate of increase is decreasing. A multi-centric community-based myocardial infarction incidence study is needed to elucidate myocardial infarction epidemiology in Iran.</p> <p class="abstract">&nbsp;</p><table cellspacing="0" cellpadding="0" align="left"><tbody><tr><td width="35" height="12"><br /></td></tr> <tr><td><br /></td> <td>&nbsp;</td></tr></tbody></table><p class="abstract">&nbsp;</p> <br /> <p class="abstract"><strong>Keywords:</strong> Myocardial Infarction (MI), Epidemiology, Prevention and control, Cardiovascular diseases, Iran, Fatality rate.</p> <p class="abstract">&nbsp;</p>
