Abstract
Background
Myeloproliferative neoplasms (MPNs) are chronic leukemias associated with increased risk of cardiovascular (CV) events. Prior studies suggest patients with MPN are at increased risk of HF. Additionally, pre-clinical murine models harboring the JAK2 mutation, the most common driver mutation in MPNs, have shown accelerated adverse cardiac remodeling in myocardial infarction and pressure overload HF models. However, clinical outcomes, including in-hospital and readmission outcomes, of patients with MPN admitted for HF have not been well characterized.
Methods
Patients hospitalized for HF with and without MPN were identified using the 2017 and 2018 National Readmission Database. Propensity score matching (PSM) was performed to match 1 MPN with 10 non-MPN controls. Outcomes were in-hospital death, 90-day CV-related, HF-related, and all-cause readmissions. Logistic regression and Cox proportional hazards regression models were used to estimate risk of in-hospital death and 90-day readmission outcomes, respectively.
Results
After PSM, 4,626 patients with MPN were matched with 46,260 without. Patients with MPN were associated with increased risk of in-hospital death (OR 1.17, 95% CI 1.00 - 1.35), 90-day CV-related (HR 1.10, 95% CI 1.02 - 1.18) and all-cause (HR 1.24, 95% CI 1.17 - 1.31) but not HF-related (HR 1.05, 95% CI 0.97 - 1.14) readmissions.
Conclusion
Among patients hospitalized for HF, MPN was associated with increased risk of in-hospital death, and 90-day CV-related readmissions (driven primarily by thrombotic readmissions). Further investigation is needed in order to improve outcomes in patients with MPN and HF.
