Underutilization of left heart catheterization in kidney transplant patients presenting with non-ST segment elevation myocardial infarction.

Background: Cardiovascular disease (CVD) is the leading cause of mortality in kidney transplant (KT) patients. The perceived risk of contrast-induced nephropathy (CIN) may create a reluctance to perform coronary angiography in patients presenting with non-ST segment elevation myocardial infarction (NSTEMI).

Methods: National Inpatient Sample (NIS) Database was used to sample individuals presenting with NSTEMI.

Liquid biopsy for non-invasive monitoring of patients with kidney transplants.

The current tools for diagnosing and monitoring native kidney diseases as well as allograft rejection in transplant patients are suboptimal. Creatinine and proteinuria are non-specific and poorly sensitive markers of injury. Tissue biopsies are invasive and carry potential complications.
