Abstract
BACKGROUND

The combination of polycythemia vera (PV) with pathological cardiac hypertrophy is uncommon. In this study, we describe a case of PV accompanied by pathological cardiac hypertrophy. It is hypothesized that the pronounced cardiac hypertrophy in this patient has a strong connection with PV.

CASE SUMMARY

In 2021, a 34-year-old Chinese man experienced chest constriction, shortness of breath, and palpitations during vigorous activity. Each episode lasted several minutes and resolved spontaneously following cessation of vigorous activity. He occasionally experienced syncope and vertigo without a headache. He underwent cardiac magnetic resonance imaging and was diagnosed with “hypertrophic cardiomyopathy (HCM)”. He was discharged after receiving symptomatic treatment, which resulted in an improvement. He presented to our department with chest constriction, shortness of breath, and respiratory distress for one month while climbing to the second floor in 2023. His blood pressure was 180/100 mmHg at the time of admittance, and he was receiving antihypertensive treatment. He had a history of PV for 2 years without treatment. Symptomatic treatment was implemented concurrently with the administration of hydroxyurea upon admission. Good blood pressure control was observed during the long-term follow-up, and echocardiography did not reveal any progression of myocardial hypertrophy.

CONCLUSION

Clinicians managing PV patients should remain highly vigilant regarding the risks of thrombosis and cardiovascular complications, particularly in those with refractory hypertension.

Keywords: Polycythemia vera; Cardiomyopathy hypertrophic; Hypertension; Thrombosis; Case report

Core Tip: Clinicians should be highly vigilant regarding the risk of thrombosis and cardiovascular complications when managing patients with polycythemia vera (PV). In young patients with hypertension, who have excluded common secondary causes and have difficult-to-control blood pressure, there should be an alert for PV. The coexistence of PV and myocardial hypertrophy is rarely reported. The myocardial hypertrophy observed in this case, which is difficult to explain for other reasons, proposes a new hypothesis that PV may be a potential trigger. Cytoreductive therapy may be an important factor in improving the patient’s myocardial hypertrophy.
