This study aimed to quantify the incidence of Contrast-induced nephropathy (CIN) in patients undergoing primary percutaneous coronary intervention (PPCI) due to acute ST-elevation myocardial infarction (STEMI). From April 2019 to March 2022, a prospective, observational study enrolled 213 consecutive STEMI patients referred to a tertiary hospital for PPCI. Participants were divided into tow groups based on the presence or absence of contrast-induced nephropathy. The chi-square test (χ2) and Student's t-test evaluated the data, with logistic regression identifying CIN's independent predictors. Results: In this study, the incidence of contrast-induced nephropathy was observed at 13.1% (N = 28). Several factors were more prevalent among patients exhibiting contrast-induced nephropathy. These factors encompassed: radial access for coronary angiography over the femoral method (P = 0.021), elevated contrast volume (P = 0.003), smoking (P = 0.009), diabetes (P = 0.04), heart failure (P = 0.049), a history of coronary artery bypass graft (P = 0.006), diminished left ventricular ejection fraction indicating systolic dysfunction (P = 0.012), cardiogenic shock (P = 0.046), increased BUN at the time of admission (P = 0.043), decreased initial GFR (P = 0.004), and prior consumption of medications such as aspirin (P = 0.002), diuretics (P = 0.046), beta blockers (P = 0.04), angiotensin-converting enzyme inhibitors (P = 0.033), angiotensin receptor blockers (P = 0.02). Other relevant conditions included anemia (P = 0.012), leukocytosis (P = 0.011), hypercholesterolemia (P = 0.034), and reduced HDL levels (P = 0.004). Through logistic regression, key predictors for the onset of contrast-induced nephropathy were determined, which included heart failure (OR: 5.52; 95% CI: 1.08–28.24), radial access (OR: 12.71; 95% CI: 1.45–110.9), hypercholesterolemia (OR: 1.02; 95% CI: 1.004–1.04), increased BUN upon admission (OR: 1.11; 95% CI: 1.006–1.24), and leukocytosis (OR: 2.03; 95% CI: 1.18–3.49). While heart failure, radial access, hypercholesterolemia, elevated BUN at admission, and leukocytosis significantly influenced renal filtration deterioration post-PPCI, it's evident that CIN is multifactorial. Further studies are crucial to elucidate the underlying factors.
