THE DIAGNOSIS OF MYOCARDIAL INFARCTION USING TROPONIN T COMPARED WITH CLINICAL AND ELECTROCARDIOGRAPHIC CRITERIA
Abstract:
The inclusion of cardiac troponin in the criteria for diagnosis of myocardial infarction led to an increase in this diagnosis. Magnitude is closely related to criteria, such as enzymes and higher values are used in conventional diagnosis of myocardial infarction since the definition varies in different studies. Increased number of myocardial infarctions generated by introducing more precise diagnostic methods and specific is not a new phenomenon in the evolution of myocardial diagnostics. It was demonstrated in the 1980s in Minnesota Heart Study that heart attacks increased attack rate by 17% or 24% when CK or CK MB activity was added diagnostic algorithm.(1) A significant proportion of patients who were initially unstable angina have now received a new diagnosis of myocardial infarction. Lately have become increasingly active pharmacological treatment and practice revascularization in patients with acute coronary syndrome. Patients with elevated levels of cardiac troponin appear to benefit most from such treatment strategies.(2)
