The measurement of the integral time-velocity of the left ventricular outflow tract (ITV-LVOT) &lt; 15 cm allows to evaluate the presence of shock.  Objective:  to evaluate the ITV-TSVI &lt; 15 cm as a predictor of cardiogenic shock in the patient with ST-segment elevation anterior acute myocardial infarction (ST-AMI).  Material and methods:  prospective observational study conducted from May to October 2019. Patients with previous ST-AMI and revascularization by percutaneous coronary intervention were included. TVI-LVOT was measured by transthoracic echocardiography, the demographic and clinical variables of patients with TVI-LVOT &lt; 15 cm vs. those with TVI-LVOT &#8805; 15 cm were recorded and compared, and the diagnostic accuracy of TVI-LVOT &lt; 15 cm to predict cardiogenic shock was calculated.  Results:  data from 50 patients were analyzed with a mean age of 63.5 ± 9.9 years, 70% were men, 54% had cardiogenic shock, and TVI-LVOT &lt; 15 cm occurred in 95.8% of those patients with shock. cardiogenic. The diagnostic accuracy of the TVI-LVOT &lt; 15 cm for cardiogenic shock in patients with anterior ST-AMI showed sensitivity of 85% and specificity of 96%, with area under the curve: 0.90 (95% CI: 0.81-0.99).  Conclusion:  The TVI-LVOT &lt; 15 cm in patients with anterior ST-AMI has a very good diagnostic accuracy for the prediction of cardiogenic shock.]]></p></abstract>
