摘要

Background

Among Asian, Native Hawaiian, and Pacific Islanders (ANHPI) in the United States, cancer and cardiovascular disease are the leading causes of death. Colorectal cancer (CRC) is the third most common cancer among ANHPIs, with improving survival rates. However, the risk of cardiovascular disease (CVD) events among ANHPI CRC survivors is unknown, especially within disaggregated ANHPI race and ethnicity groups.

Methods

We estimated the risk of CVD events among ANHPI CRC survivors within the SEER-Medicare database. Composite CVD, heart failure, ischemic heart disease, and stroke/transient ischemic attack were identified using International Classification of Diseases (ICD) diagnostic codes. Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for CVD events among ANHPI regional subgroups.

Results

Compared to non-Hispanic White (NHW) CRC survivors, the risk of composite CVD was lower among East and Southeast Asian CRC survivors at > 1 years after initial cancer diagnosis. The risk of composite CVD, heart failure, and ischemic heart disease were lower among East and Southeast Asians for follow-up > 5 years. When compared to East Asians, NHW and Southeast Asian CRC survivors had a higher risk of composite CVD, heart failure, and ischemic heart disease where South Asians had a higher risk of ischemic heart disease.

Conclusions

Within the disaggregated ANHPI race and ethnicity groups of CRC survivors, our results support heterogeneity of incident CVD events. Further research is needed to develop public health interventions to address the disparities in CVD risk, especially among the high-risk groups of South Asian and Southeast Asian CRC survivors.
