Approximately 31% of patients diagnosed with multiple myeloma (MM) have pre-existing hypertension, but its effects on patient survival have not been investigated. We collected data from 228 newly diagnosed patients with MM and found that 71 (31.1%) had pre-existing hypertension. The impact of pre-existing hypertension on MM patients was determined by evaluating progression-free survival (PFS). Kaplan-Meier analyses revealed a significantly lower PFS in the pre-existing hypertension group than their non-hypertensive counterparts (median 22.6 vs 34.8 months, respectively). The multivariable Cox proportional hazards model showed that pre-existing hypertension was an independent risk factor for PFS reduction in MM patients. Moreover, the risk of disease progression in MM patients with pre-existing hypertension was higher than in non-hypertension comparator patients (hazard ratio 1.735, 95% confidence interval 1.261-2.387). In MM patients with pre-existing hypertension, Kaplan-Meier analyses found that those with a higher risk of hypertension had a significantly shorter PFS than those with lower risk (median 19.3 vs 25.4 months, respectively). However, multivariate Cox regression analysis showed that the risk stratification of hypertension was not an independent risk factor for poor PFS in MM patients with pre-existing hypertension. Our study demonstrates that pre-existing hypertension was significantly associated with a lower PFS in newly diagnosed MM patients.
