Troponin Excretion in Urine in Patients With and Without Chronic Kidney Disease

The study population will be screened at the internal wards, the nephrology ward and clinic, and the intensive cardiac care unit (ICCU) of Soroka Medical Center. It will include patients who suffer from AMI, patients with CKD with and without any cardiac disease and patients with no known renal or cardiac disease. The following information and measurements will be collected: Demographics - age, sex, weight, height. Past medical history - specifically regarding renal and cardiac diseases and procedures. Measured variables in blood serum - troponin T, troponin I, creatinine, total protein, albumin, myoglobin Measured variables in urine - troponin T, troponin I, creatinine, total protein, albumin, microalbumin, β2-microglobulin Calculations - GFR (according to MDRD equation), troponin correction to creatinine (gr troponin per gr creatinine), troponin excretion ( ), urine albumin/creatinine ratio, urine protein/creatinine ratio.
