BACKGROUND: Contrast-induced nephropathy (CIN) is associated with poor outcomes
in patients with acute myocardial infarction. However, the predictors of CIN have
yet to be fully elucidated. METHODS AND RESULTS: The study included 273
consecutive patients with a first-time ST-segment elevation myocardial infarction
who underwent reperfusion within 12 hours of symptom onset. The exclusion
criteria were hemodialysis, mechanical ventilation, or previous coronary artery
bypass grafting. All patients underwent arterial blood gas analysis soon after
reperfusion. CIN was defined as an increase of 0.5 mg/dL in serum creatinine or a
25% increase from baseline between 48 and 72 hours after contrast medium
exposure. Acidosis was defined as an arterial blood pH <7.35. CIN was observed in
35 patients (12.8%). Multivariable logistic regression analysis with forward
stepwise algorithm revealed a significant association between CIN and the
following: reperfusion time, the prevalence of hypertension, peak creatine
kinase-MB, high-sensitivity C-reactive protein on admission, and the incidence of
acidosis (P<0.05). Multivariable logistic regression analysis revealed that the
incidence of acidosis was associated with CIN when adjusted for age, male sex,
body mass index, amount of contrast medium used, estimated glomerular filtration
rate on admission, glucose level on admission, high-sensitivity C-reactive
protein on admission, and left ventricular ejection fraction (P<0.05). Moreover,
the incidence of acidosis was associated with CIN when adjusted for the Mehran
CIN risk score (odds ratio: 2.229, P=0.049). CONCLUSIONS: The incidence of
acidosis soon after reperfusion was associated with CIN in patients with a
first-time ST-segment elevation myocardial infarction.
