Abstract
Background: Non-Hodgkin lymphoma (NHL) survivors are at increased risks of cardiovascular disease related death (CVD) compared to the general population. Objective: This study sought to determine the longitudinal trends in mortality attributed to CVD with comorbid NHL by race, sex, and geographic location. Methods: We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database among patients aged 18 and above from 1999 to 2020. Patients were identified when the primary causes of death were ischemic heart diseases (ICD 10 I20-I25), cerebrovascular diseases (I60-I69), or hypertensive disease (I10-I15), and NHL (C82-C85) was a contributing cause of death. We calculated age-adjusted mortality rates (AAMRs) per 1,000,000 individuals and determined the trends over time by estimating the annual percent change using the Joinpoint regression program. Results: In the 22-year study period, a total of 22,778 CVD with comorbid NHL were identified. Overall, there was a significant decrease in annual trends for the AAMRs of CVD from 6.91 per 1,000,000 individuals in 1999 to 4.12 per 1,000,000 individuals in 2020 (p<0.05), with an annual percent decrease of 3.3. Overall, men recorded a higher AAMRs compared to women (6.76 vs 3.45, p<0.05). When stratified by race, White individuals had the highest AAMRs (5.07), while the AAMRs for American African, Asian, American Indian individuals were 3.01, 2.77, and 2.48 per 1,000,000 individuals respectively. The AAMRs were higher in the rural region than in the urban region (4.97 vs 4.78, p<0.05). Among all consensus regions, South region had the highest AAMRs. Conclusion: In conclusion, our study revealed a significant decrease in cardiovascular disease related deaths with comorbid NHL over the past two decades. It provides valuable insights into the effectiveness of management of comorbid CVD or CVD risk factors in patients with NHL.
