Cardiovascular risk factors in hematopoietic cell transplantation survivors: role in development of subsequent cardiovascular disease.

ABSTRACT: Hematopoietic cell transplantation (HCT) recipients may be at an increased risk of developing hypertension, diabetes, and dyslipidemia (referred to as cardiovascular risk factors [CVRFs]); and these factors can potentially increase the risk of cardiovascular disease (CVD). We examined the incidence and predictors of CVRFs and subsequent CVD in 1885 consecutive 1+year survivors of HCT performed at City of Hope between 1995 and 2004. Ten-year cumulative incidence of hypertension, diabetes, dyslipidemia, and multiple (? 2) CVRFs was 37.7%, 18.1%, 46.7%, and 31.4%, respectively. The prevalence of CVRFs was significantly higher among HCT recipients compared with the general population; contributed to largely by allogeneic HCT recipients. Older age and obesity at HCT were associated with increased risk of CVRFs. History of grade II-IV acute graft versus host disease was associated with an increased risk for hypertension (relative risk [RR] = 9.1, P < .01), diabetes (RR = 5.8, P < .01), and dyslipidemia (RR = 3.2, P < .01); conditioning with total body irradiation was associated with an increased risk of diabetes (RR = 1.5, P = .01) and dyslipidemia (RR = 1.4, P < .01). There was an incremental increase in 10-year incidence of CVD by number of CVRFs (4.7% [none], 7.0% [1 CVRF], 11.2% [? 2 CVRFs], P < .01); the risk was especially high (15.0%) in patients with multiple CVRFs and pre-HCT exposure to anthracyclines or chest radiation.

Project description:BACKGROUND:The objective of this study was to evaluate whether modifiable cardiovascular risk conditions and lifestyle factors were temporally associated with an increased risk for ischemic heart disease and overall mortality in a cohort of hematopoietic cell transplantation (HCT) survivors. METHODS:HCT recipients who had survived for ?1 year, were ?20 years old, and had undergone transplantation between 1970 and 2010 at a transplant referral center were surveyed in 2010-2011 about cardiovascular health and lifestyle factors (n = 3833). Respondents (n = 2360 [61.6%]) were followed to 2016 for incident ischemic heart disease and overall mortality. RESULTS:Among the 2360 transplant survivors (median age at the baseline survey, 55.9 years; median time since transplantation, 10.8 years), 162 (6.9%) reported ischemic heart disease at the baseline survey. Among those without ischemic heart disease at the baseline survey (n = 2198), the 5-year cumulative incidence of subsequent ischemic heart disease was 4.3%. Obesity, dyslipidemia, diabetes, and physical inactivity at baseline were associated with an increased risk for subsequent ischemic heart disease (hazard ratio [HRs] ? 1.8). Greater physical activity and fruit/vegetable intake at baseline were associated with subsequent lower overall mortality (HRs ? 0.7). When jointly considered, each additional cardiovascular risk condition and each adverse lifestyle factor were independently associated with subsequent ischemic heart disease (HR for risk conditions, 1.4; 95% confidence interval [CI], 1.0-1.9; HR for lifestyle factors, 1.9; 95% CI, 1.2-2.9), and adverse lifestyle factors remained associated with overall mortality (HR, 1.8; 95% CI, 1.5-2.3). CONCLUSIONS:These results support strong efforts to promote healthy lifestyle behaviors and to treat cardiovascular risk factors aggressively in HCT survivors. This may reduce future ischemic heart disease and overall mortality in this high-risk population. Cancer 2018;124:1507-15. © 2018 American Cancer Society.

Project description:Cardiomyopathy has been recognized as a complication after hematopoietic cell transplantation (HCT). Using a nested case-cohort design, we examined the relationships between demographic, therapeutic, and selected cardiovascular disease risk factors among ≥1-year HCT survivors who developed cardiomyopathy before (n = 43) or after (n = 89) 1 year from HCT as compared to a randomly selected subcohort of survivors without cardiomyopathy (n = 444). Genomic data were available for 79 cases and 267 noncases. Clinical and genetic covariates were examined for association with the risk of early or late cardiomyopathy. Clinical risk factors associated with both early- and late-onset cardiomyopathy included anthracycline exposure ≥250 mg/m(2) and pre-existing hypertension. Among late-onset cardiomyopathy cases, the development of diabetes and ischemic heart disease further increased risk. We replicated several previously reported genetic associations among early-onset cardiomyopathy cases, including rs1786814 in CELF4, rs2232228 in HAS3, and rs17863783 in UGT1A6. None of these markers were associated with risk of late-onset cardiomyopathy. A combination of demographic, treatment, and clinical covariates predicted early-onset cardiomyopathy with reasonable accuracy (area under the curve [AUC], .76; 95% confidence interval [CI], .68 to .83), but prediction of late cardiomyopathy was poor (AUC, .59; 95% CI .53 to .67). The addition of genetic polymorphisms with marginal associations (odds ratios ≥1.3) did not enhance prediction for either early- or late-onset cardiomyopathy. Conventional cardiovascular risk factors influence the risk of both early- and late-onset cardiomyopathy in HCT survivors. Although certain genetic markers may influence the risk of early-onset disease, further work is required to validate previously reported findings and to determine how genetic information should be incorporated into clinically useful risk prediction models.
