Heart Failure in Patients with Cancer

Interest in cardio-oncology reflects increasing survival after treatment for cancer, growing awareness of the CV toxicity associated with both established and new treatments for cancer, and interest in personalized risk-profiling prior to chemotherapy. People with cardiomyopathy-related gene mutations may be more prone (7.5% of those with compared to 1.1% of those without a titin gene mutation) to develop ventricular dysfunction after the administration of chemotherapy.[131]

Interruption of trastuzumab is associated with a higher risk of cancer recurrence in women with early invasive HER2+ve breast cancer; about 60% of interruptions are for cardiotoxicity.[132] An observational study showed that of 30 women receiving HER2-targeted therapies who developed an LVEF of 40–49% and were treated prospectively with beta-blockers and ACE inhibitors, only three went on to develop severe heart failure or a LVEF <35%.[133] Cardiac function rarely returned to normal after completion of treatment, challenging the view that trastuzumab-related LV dysfunction is usually reversible. A recent study reported high rates of CV events, especially heart failure, amongst patients with multiple myeloma receiving potent proteasome inhibitors, such as carfilzomib and bortezomib,[134] which were associated with much poorer survival. Risk factors for developing a CV event included elevated pre-treatment NT-proBNP or an increase during treatment. A systematic review of prophylactic use of renin–angiotensin–aldosterone antagonists and beta-blockers identified 22 relevant RCTs, of which the largest had only 206 patients,[135,136] but found no convincing evidence of clinical efficacy
