Role of Serum Markers in Combination as a Diagnostic Tool for Acute Pulmonary Embolism: Cross-Sectional Study

Background and objective Acute pulmonary embolism (APE) is a serious cardiovascular emergency, mainly secondary to deep vein thrombosis (DVT), which causes death. The goal of the current study was to determine the levels of different serum markers in combination among patients with and without acute pulmonary embolism in order to use them as a diagnostic tool. Methodology A sample of 96 patients was kept with a 90% power of study and a 5% level of significance in the current study. It was carried from January to June 2020 in the Department of Medicine, Bahawal Victoria Hospital, Bahawalpur, after the hospital’s Ethical Committee approval. Written informed consent was taken. Serum levels of C-reactive protein (CRP), D-dimer, fibrinogen, and Troponin-I between both groups were done once enrolled. SPSS software, version 25 (IBM Corp. Armonk, NY) was used to analyze the collected data. Results Patients with acute pulmonary embolism had a mean age of 50.4 ± 10.4 years. All serum markers were significantly raised in patients suffering from acute pulmonary embolism with a p-value of <0.05. Conclusion We concluded that all these serum markers can be used together as a tool in making the correct diagnosis of acute pulmonary embolism in our setup.
