We analyzed the mortality risk of myocardial infarction (MI) patients according to renal function. Patients hospitalized for MI between 2006-18 were followed (n=5659).
We divided the sample into four groups by estimated glomerular filtration (eGFR) [mL/min]: normal functions (lowest eGFR during hospitalization >60); transient moderate insufficiency (lowest eGFR >30&60); permanent moderate insufficiency (highest eGFR >30&<=60); severe insufficiency (highest and lowest eGFR <=30). Moderate renal insufficiency indicates increased 5-years mortality, but a similar risk was found in patients with the only transient decline of renal functions.
Both moderate insufficiency subgroups (transient/permanent) did not statistically differ regarding mortality risk. In concluison the fluctuation of eGFR towards moderate insufficiency represents an important prognostic indicator in MI patients.
