Diagnostic value of cardiac troponin tnt in acute myocardial infarction

The purpose of this study was to analyze whether troponin TnT is an effective marker for identifying acute myocardial infarction (AMI). A descriptive observational study was developed based on a literature review, addressing risk factors such as age, obesity, diabetes and smoking. The process of AMI and the role of troponins in the detection and prevention of cardiac damage were also explained. Methodological tools such as PICOT and PRISMA were used to select articles that evaluated the sensitivity of troponin TnT. The results indicated a sensitivity of 48.5% and a specificity of 48.2%, concluding that it is not a sensitive marker for the early diagnosis of AMI
