- Abstract
Background: Managing acute myocardial infarction (AMI) in patients with chronic kidney disease (CKD) or end-stage renal disease on dialysis (renal replacement therapy, RRT) presents challenges due to elevated complication risks. Concerns about contrast-related kidney damage may lead to the omission of guideline-directed therapies like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in this population. Methods: We analysed German-DRG data of 2016 provided by the German Federal Bureau of Statistics (DESTATIS). We included cases with a primary diagnosis of AMI (ST-Elevation Myocardial Infarction (STEMI) or Non-ST-Elevation Myocardial Infarction (NSTEMI) ICD-10: I21 or I22) with and without CKD or RRT. We calculated crude- and age-standardized hospitalization rates (ASR, per 100,000 person years). Furthermore, we calculated log-binominal regression models adjusting for sex, CKD, RRT, comorbidities, and place of residence to estimate adjusted relative-risks (aRR) for receiving treatments of interest in AMI, such as PCI or CABG. Results: We identified 217,514 AMI-cases (69,728 STEMI-cases and 147,786 NSTEMI-cases). AMI-cases without CKD had percutaneous coronary intervention (PCI) in 60.8%. In contrast, AMI-cases with CKD or RRT had PCI in 46.6% and 54.5%, respectively. The ASR for AMI-cases amounted to 184.7 (95%CI 183.5-185.8) per 100,000 person years. In regression analysis AMI-cases with CKD were less likely treated with PCI (aRR: 0.89 (95%CI 0.88–0.90)), compared to cases without CKD. AMI-Cases with RRT showed no difference in PCI rates (aRR: 1.0 (95%CI 0.97–1.03)) but were more frequently treated with CABG (aRR: 2.20 (95%CI 2.03–2.39)). Conversely, CKD was negatively associated with CABG (aRR: 0.71, 95%CI 0.67–0.75) when non-CKD cases were used as the reference group. Conclusion: We show that AMI-cases with CKD underwent PCI less frequently, while RRT has no discernible impact on PCI utilization in AMI. Furthermore, AMI-cases with RRT exhibited a higher CABG rate. Key learning points: What was known: • In 2004, Glenn Chertow et al. coined "renalism" for low coronary intervention rates in chronic kidney disease. Fears of contrast-associated acute kidney injury led to avoiding invasive diagnostics in CKD patients with myocardial infarction. Mostly North American cohort studies consistently link underuse of percutaneous coronary intervention to higher mortality and morbidity in CKD patients. • Since then, awareness for this disadvantage has heightened and precise guidelines for the prevention of contrast-associated renal complications have been published. This study adds: • This nationwide study explores healthcare for patients with chronic kidney disease (CKD) and acute myocardial infarction. • Findings show consistently lower percutaneous coronary intervention (PCI) rates with CKD. Remarkably, cases with renal replacement therapy (RRT) had PCI rates similar to those without CKD. • "Renalism" remains a concern in Germany's healthcare landscape. Potential impact: • The outcomes of our study underscore the need for a thorough re-evaluation of the treatment approach for patients with chronic kidney disease (CKD) experiencing acute myocardial infarction. • We propose that this data serves as a catalyst for raising awareness and initiating campaigns aimed at mitigating the impact of "renalism" in routine patient care.
