Sampling method: PROBABILITY_SAMPLE
Study population: patients with chronic kidney disease having chest pain and administered to emergency department for differential diagnosis of chest pain or equivalent of chest pain (dyspnea, diaphoresis, syncope, nausea, vomiting)

Brief summary: Our study is planning to evaluate patients with chronic kidney disease who come to the emergency department with chest pain. Estimated GFR (cisGFR) with cystatin and estimated GFR (creaGFR) with creatinine will be calculated. Symptoms, ECG and troponin values of patients will be evaluated for diagnosis of acute coronary syndrome

Detailed description: Our study is planning to evaluate patients with chronic kidney disease who come to the emergency department with chest pain. Estimated GFR (cisGFR) with cystatin and estimated GFR (creaGFR) with creatinine will be calculated. Symptoms, ECG and troponin values of patients will be evaluated for diagnosis of acute coronary syndrome and the final diagnosis of AMI will be adjudicated by 2 independent cardiologists.Serial troponin measurements and eGFR values will be proportioned. These values the will be evaluated and compared for patients with acute coronary syndrome(culprit lesion on conventional coronary angiography) and non-ACS ones . With these data we aim to facilitate the diagnosis of acute coronary syndrome,increase the specificity and sensitivity of cardiac troponins for the diagnosis of acute coronary syndrome of patients with chronic kidney disease, increase the utility of high sensitive troponins for patients with chronic kidney disease. Again, with these data, it is aimed to reduce the number of false negative and false positive diagnosis of acute coronary syndrome .
