Discussion on Diagnostic Value of D-dimer and Troponin POCT in Emergency Department for Fatal Chest Pain Caused by Acute Myocardial Infarction and Acute Aortic Dissection

Abstract

Objective: to summarize and analyze application value of Point Of Care Testing (POCT) of D-dimer and troponin in diagnosis and identification of fatal chest pain caused by acute myocardial infarction and acute aortic dissection. Method: 120 patients with chest pain who were received and treated by the emergency department from June 2015 to May 2018 were chosen as the objects of study. D-dimer and troponin POCT was implemented for all patients. Finally, 58 patients were definitely diagnosed with acute myocardial infarction, and 62 patients were definitely diagnosed with acute aortic dissection. The level of D-dimer and troponin was compared and analyzed for both groups. Results: D-dimer level of patients with acute aortic dissection was higher than that of patients with acute myocardial infarction. Troponin level of patients with acute aortic dissection was lower than that of patients with acute myocardial infarction. The comparison of the above index differences had statistical significance (P<0.05). Conclusion: rapid bedside detection of D-dimer and troponin can effectively identify and diagnose fatal chest pain caused by acute myocardial infarction and acute aortic dissection, provides basis for early rescue and treatment and improve patients' prognosis, so it deserves to be promoted and applied. Acute coronary syndrome, pulmonary embolism, aortic dissection, acute myocardial infarction, cardiac tamponade and tension pneumothorax can cause fatal chest pain. The above diseases are characterized by sudden onset and fast disease changes. Timely rescue and treatment can help patients eliminate symptoms, and standard treatment can make sure patients with different diseases can receive treatment within a short time [1]. The development of POCT allows more acute disease patients to complete diagnosis at bedside and provides basis for
