Sažetak
Troponin elevation usually indicates myocardial cell injury. However, elevated values of troponin are not always a consequence of infarction or ischemia. The aim of this study was to elucidate the diverse etiologies of elevated troponin in patients with normal coronary angiography. There were 947 patients at the Zagreb University Hospital Centre identified from the catheterization database who underwent coronary angiography in 2014 due to suspected acute coronary syndrome. We identified 32 (3.38%) patients who had an alternative cause for myocyte injury other than coronary artery disease, defined as coronary artery lumen stenosis above 30%. The elevation of cardiac troponin T (cTnT) in patients with normal coronary angiography was found to be the consequence of diverse etiologies, including hypertensive heart disease, Takotsubo syndrome, supraventricular tachycardia, myocarditis, and dilated cardiomyopathy, to name a few. Apart from acute coronary syndrome, cTnT can be elevated in a number of different conditions, which should be considered according to clinical presentation, andthat could still reflect myocardial necrosis even in the absence of significant coronary artery disease.
