AMI indicates acute myocardial infarction; eGFR, estimated glomerular filtration rate; MDRD, Modification of Diet in Renal Disease; MI, myocardial infarction.
*P values for comparison AMI group vs all other diagnoses; data are expressed as medians [first quartile, third quartile], for categorical variables as numbers (percentages); eGFR in mL/min per 1.73 m2, estimated using the MDRD formula; P value for comparison AMI vs non‐AMI.
