Left Ventricular Longitudinal Strain Echocardiogram and Handgrip: A Useful Tool for Detecting Ischemia in the Emergency Room
DOI: 10.47593/2675-312X/20213404eabc238
Introduction
Acute coronary syndrome is among the greatest diagnostic challenges for emergency room physicians. Non-invasive imaging tests such as echocardiography (ECHO) are useful in the etiological diagnosis of chest pain. In cases of suspected ischemia, when electrocardiography (ECG) and myocardial necrosis markers (MNM) are inconclusive, ECHO can be performed at the time of pain or immediately after. The use of advanced techniques such as myocardial deformation analysis (strain) provides greater accuracy in identifying the coronary artery disease territory.
This report describes a case of a patient with chest pain without segmental changes on initial ECHO in the emergency room. Significant coronary artery disease (CAD) changes were evident on additional tools (handgrip, strain, and postsystolic peak) as showed on the subsequent coronary angiography.
