Does heart failure predispose to the development of cancer? Several studies have shown that patients with HF are at higher risk of developing cancer.7,8 Heart failure and cancer share common risk factors, such as ageing, male sex, obesity, diabetes mellitus, sedentariness, and smoking.9 They might both be induced by a common systemic disturbance, and HF might promote cancer development.7 Inflammation and oxidative stress are two of the main pathways involved in the etiopathogenesis of c...
