Renal Function and Cardiovascular Risk: An Overlooked Prognostic Ally

This Short Editorial is referred by the Research article "Association between Renal Function and the Incidence of Major Adverse Cardiovascular Outcomes 1 Year After the First Acute Myocardial Infarction".
The subanalysis of the Catarina Heart Study brings relevant and timely evidence to a well-known yet often underappreciated clinical relationship: the impact of renal function on cardiovascular outcomes. By showing that lower creatinine clearance at hospital admission independently predicts major adverse cardiovascular events (MACE) and mortality after acute myocardial infarction (AMI), the study reinforces the kidney as an essential prognostic organ in cardiology.
Cardiorenal interaction is not a novel concept. The bidirectional relationship between the heart and kidneys has been documented in large-scale studies like the Chronic Kidney Disease Prognosis Consortium and ARIC. What makes the present analysis relevant is its practical and local applicability: in a Brazilian population, using a simple, widely available tool—creatinine clearance by the Cockcroft-Gault formula—clinicians can identify high-risk patients early in the course of AMI.
