Cardiac Complications of Myeloproliferative Disorders

Area of Science:

• Cardiology
• Hematology
• Oncology

Background:

• Thrombosis complicates approximately one-third of myeloproliferative disorders (MPDs), leading to 15%-40% mortality.
• MPD-associated thrombosis affects various circulations, including arterial, venous, hepatic, mesenteric, portal, and cardiac systems.
• Cardiovascular involvement ranges from 4% to 21% in MPD patients, with acute ischemic coronary artery disease presenting symptoms.

Purpose of the Study:

• To review the existing literature on the association between cardiac diseases and myeloproliferative disorders.
• To emphasize the importance of considering MPDs in young patients with cardiac conditions.

Main Methods:

• Literature review of studies investigating the link between cardiac diseases and MPDs.
• Analysis of reported cases, focusing on patient demographics and clinical presentations.

Main Results:

• Thrombosis is a major complication of MPDs, affecting diverse vascular beds.
• Cardiac involvement, including coronary artery disease, can be an initial manifestation of MPDs, especially in younger individuals.
• A significant proportion of MPD cases involve thrombotic events.

Conclusions:

• Myeloproliferative disorders represent a critical underlying cause of cardiac disease, particularly in young patients without conventional risk factors.
• Clinicians should maintain a high index of suspicion for MPDs in young patients presenting with cardiac disease.
• Early diagnosis and management of MPDs can mitigate thrombotic complications and improve patient outcomes.
