Diagnostic Value of cTnl, NT-pro BNP, and Combined Tests in Acute Myocardial Infarction Patients.

Acute myocardial infarction (AMI) is characterized by heart damage resulting from blocked blood flow. Prompt diagnosis is vital for timely treatment and saving lives. This study aimed to evaluate the diagnostic value of cTnl, NT-pro BNP, and a combined test in AMI patients. In this study, a retrospective observational design was employed, and we selected 221 patients with AMI admitted to our hospital within a 3-year period as the research subjects and included them in the AMI group. Additionally, 200 patients from the control group, who visited our hospital for physical examinations, were selected to compare the expressions of cardiac Troponin I (cTnl) and N-Terminal pro-B-type Natriuretic Peptide (NT-pro BNP) between the two groups. Receiver Operating Characteristic (ROC) curves were constructed to analyze the diagnostic value of cTnl combined with NT-pro BNP for AMI. Furthermore, AMI patients were categorized into four groups based on the New York Heart Association (NYHA) classification (grades I, II, III, and IV). The differences in cTnl, NT-pro BNP, and Left Ventricular Ejection Fraction (LVEF) were compared among the AMI patients with different cardiac function grades to analyze their correlation and diagnostic value in assessing the severity of AMI-related cardiac insufficiency. The levels of cTnl and NT-pro BNP in AMI patients were significantly higher than those in the control group, and their combined detection effectively facilitated the diagnosis of AMI occurrence. Moreover, cTnl and NT-pro BNP concentrations increased with the severity of cardiac dysfunction (NYHA grades) and showed a notable negative correlation with LVEF. Furthermore, the combined testing of cTnl and NT-pro BNP demonstrated significant value in evaluating the severity of AMI in patients. The combined detection of cTnl and NT-pro BNP holds considerable application value in diagnosing AMI occurrence and assessing its severity.
