Use of sglt2–inhibitors in the treatment of anthracicline cardiotoxicity
European Heart Journal Supplements(2024)
Abstract
Abstract The survival rate of cancer patients has significantly increased in the last 25 years thanks to the extraordinary advances in anti-tumor therapies. However, many chemotherapeutic agents are potentially cardiotoxic. In particular, anthracycline-induced cardiotoxicity is a clinical condition caused by chemotherapy drugs that lead to morpho-functional alterations and cell death of cardiomyocytes; the most typical clinical manifestation of this cardiotoxicity is the development of left ventricular dysfunction, which over time can evolve towards full-blown heart failure. It is therefore characterized by a reversible asymptomatic stage that progresses to an irreversible stage, often difficult to treat. For an early individualization of this toxicity, a dedicated clinic has been established in our center for the monitoring of patients undergoing treatment with cardiotoxic chemotherapy. We describe the case of a 53-year-old patient with preserved biventricular systolic function undergoing neoadjuvant treatment for breast cancer, who at the end of the second infusion of anthracyclines presented with mild exertional dyspnoea associated with radiological signs of pulmonary congestion and an increase in the indices of myocardionecrosis and BNP. The echocardiogram revealed a sudden worsening of the left ventricular systolic function which was 48%. It was therefore decided to hospitalize the patient and initiate infusional diuretic therapy with a rapid clinical and instrumental response. An SGLT2 inhibitor with indication for the treatment of heart failure with moderately reduced ejection fraction was also added to the therapy. At the one-month check-up, there was an almost complete recovery of left ventricular function and a clear symptomatic benefit with associated normalization of laboratory markers of myocardial damage and heart failure, with the possibility for the patient to undergo surgery to remove the left ventricle. tumor mass. This clinical case could represent a starting point to start considering therapy with SGLT2 inhibitors for the prevention and early treatment of cardiac toxicities from some chemotherapeutics, in order to avoid the process of irreversibility of myocardial damage with subsequent poor response to anti-inflammatory therapies. – conventional compensation.
