What is the role of bedside transthoracic echocardiography (POCUS) in suspected ACS?

In suspected ACS, bedside echocardiography is used to rapidly assess cardiac function and structure to guide immediate management. It can show how well the left ventricle is contracting and reveal regional wall-motion abnormalities that point to ischemia in specific coronary territories. It also evaluates the right ventricle for signs of strain or dysfunction, which matters in inferior/posterior MI or RV infarct, and looks for pericardial effusion or tamponade and for acute valvular problems that could worsen hemodynamics. This information helps clinicians decide on interventions and therapies—such as fluids, inotropes, or avoidance of certain meds—while awaiting definitive tests. Troponin levels require blood tests and are not obtained through imaging, and while echo may incidentally suggest pulmonary embolism, its primary role in suspected ACS is the broad, rapid assessment to guide management, not to detect PE alone.
