Background:Heart failure (HF) and cancer (CA) are becoming increasingly prevalent as the population ages. We aimed to evaluate prior history and occurrence of CA and its prognostic impact on HF.Methods and Results:Consecutive hospitalized HF patients (n=2,103) were divided into 2 groups according to prior history of CA: non-prior-CA group (n=1,828) and prior-CA group (n=275). Compared with the non-prior-CA group, the prior-CA group were older, and had higher prevalence of chronic kidney disease, anemia, and atrial fibrillation (P<0.05). In contrast, sex, other comorbidities, levels of natriuretic peptide and ejection fraction were comparable between groups. We focused on newly diagnosed CA after discharge for HF. In the follow-up period (median 623 days), 114 (6.2%) patients in the non-prior-CA and 17 (6.2%) patients in the prior-CA groups were newly diagnosed as having CA. Additionally, 83 (3.9%) CA-related patient deaths occurred (median 776 days). In the Kaplan-Meier analysis (median 1,037 days), not only all-cause death but also cardiac event rate was significantly higher in the prior-CA group than in the non-prior-CA group (log-rank P<0.01). In the Cox proportional hazard analysis, CA history was a predictor of cardiac event rate (HR 1.450, 95% CI 1.134–1.822), as well as all-cause death (HR 2.483, 95% CI 2.034–3.030).Conclusions:Prior-CA history was associated with high cardiac event and mortality rates. CA is notable comorbidity in HF patients.

We examine the relationship between the record-warm winter (DJF) 2019/2020 over East Asia and the extremely weak hemispheric circulation anomaly. During this period, the polar cold-air mass (PCAM) flux over East Asia was the weakest on record since the DJF 1958/1959 due to the weak Siberian High. The zonal averaged surface temperature over the Northern Hemisphere mid-latitudes in DJF 2019/2020 was the highest since DJF 1958/1959 and was linked to the weakest PCAM flux at the mid-latitudes. The zonal mean field during this period was characterized by weak stationary waves, weak wave activity as diagnosed by Eliassen-Palm flux, and, to balance with this, record-weak extratropical direct meridional circulation (EDC). The weak EDC corresponded to weaker-than-normal meridional heat exchange and was consistent with warm anomalies in the Northern Hemisphere mid-latitudes, since the lower branch of EDC corresponds to zonally averaged cold air outflow. In addition, the statistical relationship also indicates the EDC intensity is negatively correlated with the surface temperature anomaly over East Asia.
