Abstract
Background: Percutaneous coronary intervention (PCI) is vital for managing coronary artery disease (CAD). It significantly reduces mortality and morbidity. Yet, PCI carries risks like contrast-induced nephropathy (CIN). CIN harms renal function, prolongs hospital stays, and raises healthcare costs and mortality rates. Preventive strategies, including hydration therapy, aim to mitigate CIN, particularly in high-risk patients with pre-existing conditions.
Objective: This study aimed to evaluate the impact of CIN prevention strategies, especially hydration therapy, on PCI outcomes in high-risk Pakistani patients.
Methods: Conducted at Hayatabad Medical Complex, Peshawar, from January 2021 to December 2022, this study included 132 high-risk patients undergoing PCI. Participants were randomly assigned to receive either hydration therapy or no specific hydration protocol. The primary outcome was the incidence of CIN, defined as an increase in serum creatinine by 0.5 mg/dL or 25% from baseline within 30 days post-PCI. Secondary outcomes included the length of hospital stay and 30-day mortality rate. Data were collected through medical records and direct interviews. Statistical analyses were performed using SPSS version 26.0.
Results: The incidence of CIN was 10.6%, with the highest rates in patients with pre-existing chronic kidney disease (CKD) (18.4%). Hydration therapy significantly reduced CIN incidence to 5.4% compared to 15.7% in those without hydration. Patients with CIN had longer hospital stays (mean ± SD: 6.3 ± 2.1 days) compared to those without CIN (4.1 ± 1.5 days). The 30-day mortality rate was higher in CIN patients (7.1%) versus non-CIN patients (2.9%). Statistical analyses demonstrated significant differences in CIN incidence, hospital stay length, and 30-day mortality rates among the groups, with p-values < 0.05.
Conclusion: Hydration therapy significantly reduces CIN incidence and improves outcomes for high-risk Pakistani patients undergoing PCI. Routine hydration protocols in clinical practice can enhance patient care, reduce healthcare costs, and improve overall CAD management in Pakistan. Future research should focus on long-term outcomes, cost-effectiveness, and the influence of genetic and environmental factors on CIN.
