Cardiovascular disease in thymic cancer patients

Area of Science:

• Cardiology
• Oncology
• Epidemiology

Background:

• Cancer patients are at increased risk for adverse cardiac events.
• Cardiovascular risk in thymic cancer patients is not well understood.
• Baseline cardiometabolic risk factors and treatment effects on cardiac events require characterization.

Purpose of the Study:

• To characterize baseline cardiometabolic risk factors in thymic cancer patients.
• To assess the association between thymic cancer treatment and subsequent cardiac events.

Main Methods:

• Retrospective cohort study comparing thymic cancer patients (TCPs) to noncancer controls (2003-2020).
• Data collected on baseline cardiovascular risk factors, cancer characteristics, and cardiac events.
• Multivariable regression analysis to evaluate risk factors and cancer therapies.

Main Results:

• TCPs had a higher incidence of cardiac events compared to controls (HR 1.38, p=0.042).
• High-risk TCPs (≥2 risk factors or pre-existing CVD) showed significantly higher cardiac event risk (HR 3.73, p<0.001).
• Radiotherapy or chemotherapy in high-risk TCPs further elevated cardiac event risk (HR 4.99, p<0.001; HR 6.24, p<0.001).

Conclusions:

• Thymic cancer patients experience more cardiac events than controls, even after risk factor adjustment.
• Patients with multiple cardiovascular risk factors undergoing radiotherapy or chemotherapy face a substantially higher risk of cardiac events.
