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.
Purpose:
Prevention of vascular events is the main objective in patients with polycythemia vera (PV) or essential thrombocythemia (ET). Carotid ultrasonography (USG) is a safe and noninvasive diagnostic tool that can be used to stratify cardiovascular and stroke risks. In our previous study, carotid plaque burden was significantly higher in patients with PV/ET than in the general population. This study aimed to determine changes in carotid plaques in patients with PV/ET.
Methods:
We retrospectively evaluated the medical records of patients with ET/PV who had undergone carotid USG at least twice.
Results:
Of the 56 patients, 30 had PV and 26 had ET. The carotid plaque score was increased in the follow-up carotid USG compared with that in the initial carotid USG (3.38 ± 1.47 vs. 3.73 ± 1.46, p = 0.0139). The carotid plaque burden at the time of follow-up carotid USG showed no significant differences in patients with a complete hematologic response (CHR); however, it significantly worsened in patients who failed to achieve CHR.
Conclusion:
We confirmed that the carotid plaque burden persisted during follow-up in patients with PV/ET. A CHR may prevent an increase in carotid plaque burden.

Disorders of Erythrocytes
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.
