Abstract
- Background: Patients undergoing autologous hematopoietic cell transplantation (HCT) have a >2‐fold risk of developing cardiovascular disease (CVD; heart failure, myocardial infarction, and stroke), compared to the general population. Coronary artery calcium (CAC) is predictive of CVD in nononcology patients but is not as well studied in patients who underwent HCT and survivors of HCT.The objective of this study was to examine the association between CAC and CVD risk and outcomes after HCT in patients with lymphoma. Methods: This was a retrospective cohort study of 243 consecutive patients who underwent a first autologous HCT for lymphoma between 2009 and 2014. CAC (Agatston score) was determined from chest computed tomography obtained <60 days from HCT. Multivariable Cox regression analysis was used to calculate hazard ratio (HR) estimates and 95% confidence intervals (CIs), adjusted for covariates (age, conventional risk factors [e.g., hypertension and dyslipidemia], and cancer treatment). Results: The median age at HCT was 55.7 years (range, 18.5–75.1 years), 59% were male, and 60% were non‐Hispanic White. The prevalence of CAC was 37%. The 5‐year CVD incidence for the cohort was 12%, and there was an incremental increase in the incidence according to CAC score: 0 (6%), 1–100 (20%), and >100 (32%) (p =.001). CAC was significantly associated with CVD risk (HR, 3.0; 95% CI, 1.2–7.5) and worse 5‐year survival (77% vs. 50%; p <.001; HR, 2.0; 95% CI, 1.1–3.4), compared to those without CAC. Conclusions: CAC is independently associated with CVD and survival after HCT. This highlights the importance of integrating readily available imaging information in risk stratification and decision‐making in patients undergoing HCT, which sets the stage for strategies to optimize outcomes after HCT. Hematopoietic cell transplantation (HCT) survivors have an increased risk of cardiovascular disease (CVD) compared to the general population, and therefore thorough assessment of cardiovascular risk before HCT is essential. This study showed that the coronary artery calcium (CAC) score, obtained from routine pretransplant imaging, is significantly associated with CVD posttransplant and is a useful addition to traditional cardiovascular risk factors. Further prospective studies are needed to understand how CAC screening should be formally incorporated into pretransplant workup, cardiovascular risk assessment, and clinical decision‐making and its effect on posttransplant outcomes.
