Exploring the correlation between radial artery access and decreased occurrence of contrast-induced nephropathy.

Abstract

Objective: To Investigate the Impact of Radial Artery Access on Contrast-Induced Nephropathy (CIN) Incidence. Study Design:                Retrospective study. Setting: Department of Cardiology, Hayatabad Medical Complex in Peshawar. Period: January 2021 to June 2022. Material & Methods: Patients aged ≥ 30 who have undergone cardiac catheterization procedures, with a focus on those who have undergone the procedure using radial artery access. Those patients who had pre-existing renal impairments or kidney diseases, with a history of contrast allergies, were included in the study. However, those patients who were under the age of < 30, had undergone cardiac catheterization procedures using femoral artery access, and with incomplete medical records were excluded. All the data were analyzed in SPSS version 26. Results: In our study involving 164 participants. Individuals who experienced CIN exhibited a considerably greater average age of 69.89 years when contrasted with the 66.86 years of those in the non-CIN category (p=0.03). Furthermore, a higher percentage of patients in the CIN group were aged 65 or older (35.1% vs. 11%, p<0.001), highlighting the increased vulnerability of older individuals to CIN. The timing of reperfusion therapy, indicated by the time-to-reperfusion, was significantly longer in the CIN group (6.2 ± 3.3 hours) compared to the non-CIN group (4.9 ± 3.7 hours, p=0.001), suggesting that delayed reperfusion may be a risk factor for CIN. Conclusion: Patients with anterior infarction, delayed reperfusion, lower left ventricular ejection fraction (LVEF), and higher serum creatinine levels were also more likely to develop CIN.
