The quest for equilibrium: exploring the thin red line between bleeding and ischaemic risks in the management of acute coronary syndromes in chronic kidney disease patients

摘要

Coronary artery disease and acute coronary syndrome (ACS) are both common in patients with chronic kidney disease (CKD). CKD patients have higher risks of bleeding and thrombosis. However, they remain under-represented in major randomized clinical trials (RCTs), and there is no medical evidence-based foundation on which to issue specific recommendations about the management of ACS in CKD. CKD patients with ACS frequently are diagnosed later, receive fewer acute interventions and are at increased risk of over-dosage of medications and under-prescription/under-performance of interventional treatments than CKD patients without ACS. The lack of RCTs should not discourage reliance on clinical common sense, while clearer decisional algorithms with better outcomes are a priority for urgent development. Future guidelines should further refine the assessment of CKD with ACS while placing much greater emphasis on the correct dosing of medications based on contemporaneous renal function. Until a strategy is designed with specific measures translated into the actual decrease of bleeding risk, providers will be forced to balance the equilibrium on a thin red line that is not clearly established.
