Speckle-tracking echocardiography: a tool for early detection of cardiotoxicity in cancer patients after chemotherapy

In modern oncology, despite the efficacy of chemotherapy, there is a risk of cardiotoxicity resulting in heart failure. This necessitates early diagnosis to prevent complications and improve prognosis. The study is aimed at analysing the abilities of speckle-tracking echocardiography as a modern tool in detecting cardiotoxicity in the early stages. This non-invasive method allows evaluating myocardial strain and its contractility. During a thorough analysis and extensive review of the scientific literature, it was found that the speckle-tracking echocardiography technique demonstrates an exceptionally high sensitivity to detecting early signs of cardiotoxicity, significantly outpacing conventional echocardiography methods in this aspect. This advantage makes it an invaluable tool in the early detection of potentially dangerous changes in the myocardium, which is especially important for patients at risk of developing cardiotoxic reactions as a result of chemotherapy. Speckle-tracking echocardiography has a unique ability to identify even the slightest local abnormalities in the structure and function of the myocardium, significantly before any clinical symptoms become apparent, thereby allowing doctors to take preventive measures at the earliest stages. This outstanding diagnostic ability is supported by an extensive body of scientific research and publications that unequivocally confirm the effectiveness of speckle-tracking echocardiography as an advanced tool for the early diagnosis of cardiotoxic changes. Thus, the timely application of this technique can significantly reduce the risks to the cardiac health of patients and contribute to more effective treatment of oncological diseases. Speckle-tracking echocardiography serves as an important tool in the early detection of cardiotoxicity in patients undergoing chemotherapy, allowing clinicians to timely adapt treatment protocols and prevent the development of serious cardiovascular complications, thereby improving the prognosis and quality of life of cancer patients.
