HF occurs in patients with cancer as a result of the interaction among anticancer therapy, cancer itself, and patients’ CV background (risk factors and coexisting CV disease).
842846Several anticancer thera- pies may cause HF directly, thorough their cardiotoxic effects (Table 23), or, indirectly, through other mechanisms, such as myocarditis, ischaemia, systemic or pulmonary hypertension, arrhythmias or valve disease.
844,845,847852HF, in turn, may affect cancer outcomes by depriving patients of effective anticancer therapies.
699Some epide- miological and experimental evidence suggests a further reciprocal interaction between cancer and HF with some, though not all, studies showing a higher incidence rate of cancer in patients with HF.
853858The prevention of HF in patients with cancer undergoing potential cardiotoxic therapies requires careful patient’s assessment and man- agement before, during, and after cancer therapy, preferably in the context of an integrated Cardio-Oncology service (Figure 18).
845,859,860A CV baseline risk assessment for all patients scheduled to receive potentially cardiotoxic cancer therapies using the HFA-ICOS risk assessment is advisable.
846Baseline CV risk assessment forms have been developed for different potentially car- diotoxic cancer therapies. History of HF or CMP characterizes patients as being at very high risk or at high risk for all cancer thera- pies, except anti-androgen treatments for prostate cancer. An LVEF
<50% is an additional factor for high-risk patients and elevated levels

of NPs or troponin at baseline are additional criteria of medium risk for most of the cancer treatments.
846During cancer treatment with potential cardiotoxic therapies, LV systolic function can be monitored through echocardiography.
Chemotherapy should be reconsidered and treatment with an ACE-I and a beta-blocker (preferably carvedilol) should be started in patients who develop LV systolic dysfunction, defined as 10% or more absolute reduction in LVEF to a value below 50%.
844,861864Global longitudinal strain can detect cardiac dysfunction at an earlier stage.
865,866A > _12% relative reduction in global longitudinal strain was compared with an LVEF decline in a prospective randomized trial in high-risk patients undergoing potentially cardiotoxic chemother- apy. Compared to treatment based on LVEF, treatment based on changes in global longitudinal strain led to the same decrease in LVEF (primary endpoint) but with fewer patients who developed cardiac dysfunction at the end of the study, thus suggesting usefulness of global longitudinal strain for the early detection of cardiotoxicity.
867Promising results for the early detection of cardiac dysfunction have also been obtained through monitoring of biomarkers, such as NPs and troponin.
868,869Patients on immunotherapy with immune check- point inhibitors are at increased risk of myocarditis and should be monitored for related symptoms and signs and by weekly assessment of cardiac troponin during at least the first 6 weeks of therapy and managed accordingly.
870Timing of the imaging procedures and biomarkers assessment depend on the anticancer treatment and patient’s risk profile (Figure 18).
865In general, all patients scheduled for potential cardi- otoxic therapies must undergo a baseline evaluation that would define the level of risk for cardiotoxicity (low, medium, or high) and the intensity of monitoring and follow-up during and after cancer treatment.
865Cancer survivors exposed to potentially cardiotoxic therapies should be periodically monitored in the long term as HF may develop several years after cancer therapy.
