Pulmonary Embolism in Patients with CKD and ESRD

Abstract: SummaryBackground and objectives CKD and ESRD are growing burdens. It is unclear whether these conditions affect pulmonary embolism (PE) risk, given that they affect both procoagulant and anticoagulant factors. This study examined the frequency and associated outcomes of PE in CKD and ESRD.Design, setting, participants, & measurements The Healthcare Cost and Utilization Project's Nationwide Inpatient Sample was used to estimate the frequency and outcomes of PE in adults with CKD and ESRD. Hospitalizations for … Show more

“…This index uses 17 comorbid conditions with differential weighting and total scores ranging from 0 to 33, with higher scores representing greater comorbidity burden. In accordance with the previous literature, 27 we excluded kidney disease when calculating the index because that was already included as patient characteristic. Patients were also categorized based on insurance status into Medicare/Medicaid, private/health maintenance organization, or no insurance.…”

“…14 Patients with diagnosis codes for head trauma (ICD-9-CM codes 800.0-804.9, 850.0-854.1, and 873.0-873.9) and cerebrovascular malformations (747.81) were excluded. In accordance with previous literature, 15 maintenance dialysis status was defined as patients with an ICD-9-CM code for end-stage renal disease (585.6) or procedure code for hemodialysis (39.95) or peritoneal dialysis (54.98) but absence of ICD-9-CM code for acute kidney injury (584.X). Since the ICD-9-CM code for end-stage renal disease (585.…”

“…Moreover, elevated hematocrit levels are reported to promote activation of factor IX (an intrinsic factor for coagulation cascade) by erythroelastase IX (factor IX-activating enzyme) in erythrocytes, which could further enhance the coagulation pathway [5,6]. In addition, patients with reduced renal function are more likely to develop pulmonary thromboembolism than those with normal kidney function [7]. Possible mechanisms for the phenomenon include enhanced activation of factor XIIa, factor VIIa, and fibrinogen, as well as inhibition of von Willebrand factor and tissue plasminogen activator in the patients with reduced renal function [8,9].…”
