Effects of TIMI risk index on predicting prognosis m patients with ST-elevation myocardial infarction / 中华急诊医学杂志

ABSTRACT

Objective To evaluate the value of the TIMI risk index in predicting 30-day and one-yosr mortality and incidence of heart failure in patients with ST-elevation myocardial infarction (STEMI).Method Data of 229 patients with STEM1 from August 1999 to March 2006 in the First Affiliated Hospital,Sun Yat-sen University,were retrospeclively collected,analyzed and scored with TIMI risk index.When categorized into quintiles(≤12.5,12.5～17.5,17.5～22.5,22.5～30,>30) and modeled as a continuous variable,difference of prediction of 30day and one-year mortality and 30-day incidence of heart failure of patients were compared respectively.Results When categorized into quintilos and modeled as a continuous variable,30-day and one-year mortality and 30-day incidence of heart failure were increasing with increasing score of risk index (P<0.05).The area under the recewer operating characteristic curve were 0.65,0.68,0.67 and 0.70,0.72,0.70,respectively.Conclusions The TIM1 risk index can be used as a simple,rapid and practical tool to risk-stratify patients with STEMI.
