The patient had experienced non-specific symptoms during dialysis. The ECG showed signs of left ventricular hypertrophy, while the coronary angiogram revealed a corkscrew-like tortuosity of the left circumflex artery accompanied by chronic hypertension. Given the high clinical likelihood of CHD, careful assessment is required. Furthermore, since elevated cTnT-hs levels would be expected in these patients, serial measurements are needed. According to the recommendation published by the NACB8, based on the use of less sensitive cTn generations (e.g. cTnT Gen 4), an increase of more than 20 % for a repeat measurement after 6 – 9 hours is indicative of an acute event.22
