Tei index, defined as the sum of isovolumic contraction and relaxation times divided by ejection time, has been proposed to express global left ventricular function. For patients with acute myocardial infarction (AMI), left ventricular function can potentially be a major determinant of hemodynamics with limited time for compensation, such as increased brain natriuretic peptide to attenuate congestion, and usually without any intervention to modify cardiac loading on arrival at the hospital during the acute phase. We, therefore, hypothesized that left ventricular function, expressed by the Tei index, allows noninvasive estimation of impaired hemodynamics for patients with AMI.
