Insights

Patients with myeloproliferative neoplasms (MPN) undergoing percutaneous coronary intervention (PCI) have stable prevalence but increased risks of blood transfusions and acute kidney injury (AKI). Further research is needed to improve outcomes for this high-risk group.

Area of Science:

  • Cardiology
  • Hematology
  • Clinical Research

Background:

  • Myeloproliferative neoplasms (MPN) increase cardiovascular risk, including acute coronary syndrome.
  • Limited data exists on percutaneous coronary intervention (PCI) rates, characteristics, and outcomes in MPN patients.

Purpose of the Study:

  • To evaluate temporal trends and outcomes of PCI in patients with MPN.
  • To compare in-hospital characteristics and outcomes between MPN and non-MPN patients undergoing PCI.

Main Methods:

  • Utilized the National Inpatient Sample database (2016-2020) for PCI hospitalizations.
  • Analyzed temporal trends and outcomes, employing propensity score matching (PSM) for comparison.
  • Included 2,237,210 PCI hospitalizations, with 7,560 (0.27%) involving patients with MPN.

Main Results:

  • MPN prevalence among PCI admissions remained stable (0.27%) from 2016-2020.
  • MPN patients had higher rates of cardiovascular comorbidities.
  • Post-PSM, MPN was linked to increased risk of blood transfusions (OR: 1.66) and acute kidney injury (AKI) (OR: 1.39).

Conclusions:

  • MPN prevalence in PCI patients is stable, but associated with higher risks of blood transfusion and AKI.
  • In-hospital mortality and bleeding risks did not significantly differ between MPN and non-MPN groups post-PSM.
  • Further investigation is crucial to understand and mitigate increased risks in MPN patients undergoing PCI.
