PoCUS may aid early diagnosis and revascularization of occult occlusive MI in ICU patients
USA: Cardiac PoCUS (point-of-care ultrasound) may help identify occult occlusive myocardial infarction (OOMI) earlier than standard evaluation and may expedite definitive management in patients in the emergency department, states the study results published in The American Journal of Emergency Medicine. PoCUS may be used as a rapid, reliable, diagnostic tool in ED.
A greater proportion of patients are receiving their initial care and diagnostic testing in emergency departments (EDs) With the ever-changing landscape of health care delivery globally. Expediting triage and time to diagnosis is crucial in decreasing morbidity and mortality in critically ill patients and significant efforts have been made for its achievement. Point-of-care ultrasound (PoCUS) in the ED is one of the point-of-care testing tools available to the emergency physician which answers specific clinical questions that narrow differentials, guide clinical therapy, and direct consultations and disposition.
Electrocardiographically occult occlusive myocardial infarction (OOMI) is a coronary artery occlusion requiring revascularization. Occlusive myocardial infarction diagnosis without ECG ST-elevation can take hours and delayed diagnosis is associated with increased mortality. Left ventricular (LV) wall motion abnormalities (WMA) visible on PoCUS can expedite OOMI diagnosis.
Curtis Xu, University of Connecticut School of Medicine, USA, and colleagues sought to determine whether PoCUS demonstrating WMA expedites revascularization time when performed on emergency department patients being evaluated for OOMI.
