- Description
- Background: The association between cardiovascular disease and carcinogenesis is bidirectional and well-established. Furthermore, cancer treatment improves overall patient survival, potentially at the cost of incremental and fatal cardiovascular disease (CVD) Aim: To evaluate (a) In a real-world cohort, the proportion of patients offered cancer chemotherapy who have antecedent CVD (CVDA); (b) The rates of patient admission with subsequent development of CVD (CVDS) requiring hospital admission post assignment to chemotherapy; (c) The impact of CVDA and CVDS on mortality rates relative to those seen in patients without overt CVD (CVD−) and (d) The time course of mortality in CVD− versus CVDS patients. Methods: Retrospective analysis was performed in deidentified linked health data sets. Correlates of mortality were evaluated by Cox proportional hazards evaluation. Relative and absolute time-variability of CVD as a primary cause of death were determined. Results: Of the total 17,389 patients, there were 2,159 with CVDA. Over a median follow-up time of 4.6 years, CVDS admissions (n = 8,529) occurred more commonly in the presence of CVDA (70.0% vs. 46.1%, p < 0.001), and more than 50% of CVDS cases occurred in the first 12 months of follow-up. The 5-year mortality rates were 71.5% for CVDA, 64.7% for CVDS, and 40.8% for CVD− (p < 0.001). Development of CVDS was associated with a substantially increased risk of mortality in the next 12 months. The development of CVDs was also associated with an increased risk of cardiovascular, as against non-cardiovascular, mortality (7.1% vs. 1.6%, p < 0.001). Conclusions: Approximately 50% of patients assigned to cancer chemotherapy developed CVDS, heralding a particularly high risk of mortality over the next 12 months. Both CVDA and CVDS are associated with substantial increases in mortality rates relative to those in CVD− patients. This increased risk merits close individual monitoring.
