Insights

Carotid plaque burden persists in patients with polycythemia vera (PV) and essential thrombocythemia (ET). Achieving a complete hematologic response (CHR) may prevent worsening of carotid plaque burden in these high-risk patients.

Area of Science:

  • Cardiovascular Medicine
  • Hematology
  • Diagnostic Imaging

Background:

  • Vascular event prevention is crucial for polycythemia vera (PV) and essential thrombocythemia (ET) patients.
  • Carotid ultrasonography (USG) is a valuable tool for cardiovascular and stroke risk stratification.
  • Previous research indicated higher carotid plaque burden in PV/ET patients compared to the general population.

Purpose of the Study:

  • To investigate changes in carotid plaque burden over time in patients diagnosed with PV or ET.
  • To assess the impact of hematologic response on carotid plaque progression in PV/ET patients.

Main Methods:

  • Retrospective analysis of medical records for patients with ET/PV who underwent at least two carotid USG examinations.
  • Evaluation of carotid plaque scores from initial and follow-up USG procedures.

Main Results:

  • A statistically significant increase in carotid plaque score was observed between initial and follow-up USG (p=0.0139).
  • Carotid plaque burden did not significantly differ in patients achieving a complete hematologic response (CHR).
  • Patients failing to achieve CHR showed a significant worsening of carotid plaque burden.

Conclusions:

  • Carotid plaque burden is persistent in patients with PV and ET during follow-up.
  • Achieving a complete hematologic response (CHR) may be a protective factor against the progression of carotid plaque burden in PV/ET patients.

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Venous Thrombosis I: Introduction01:30

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
