Clinical and Diagnostic Significance of Endothelial Dysfunction and Myocardial Contractility in Patients With AML

Clinical and Diagnostic Significance of Endothelial Dysfunction and Myocardial Contractility in Patients With Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clonal neoplastic disease of the hematopoietic tissue associated with a mutation in the precursor cell of hematopoiesis, which results in a differentiation block and uncontrolled proliferation of immature myeloid cells.

Anthracycline antibiotics have been an integral part of the treatment of acute myeloid leukemia since the 1970s. However, the clinical usefulness of anthracyclines is limited primarily by the high incidence of cardiotoxicity. According to the European Society of Cardiology guidelines for cardio-oncology, cardiovascular toxicity is defined as any impairment of cardiac function associated with anticancer treatment, as the term encompasses both a wide range of possible clinical manifestations and an etiological relationship with various treatments, including chemotherapy, radiation therapy, immunotherapy and treatment with targeted drugs. Cardiovascular toxicity can be acute, subacute or delayed, manifesting many years after chemotherapy or radiation therapy, involving a number of cardiac structures, which can lead to the development of heart failure, coronary heart disease, valvular heart disease, arrhythmias, including cardiac conduction disorders and diseases of the pericardium.

Anthracycline-induced cardiotoxicity is the negative effect of anthracyclines on normal cardiac activity due to their toxic effects on the heart muscle and the cardiac conduction system. Anthracycline-induced cardiotoxicity manifests as asymptomatic left ventricular dysfunction in 57% of treated patients and restrictive or dilated cardiomyopathy leading to congestive heart failure (CHF) in 16% to 20% of patients. Anthracycline-induced congestive heart failure is often resistant to therapy and has a mortality rate of up to 79%. Thus, there is a need for early detection of cardiovascular dysfunction associated with chemotherapy treatment of acute myeloid leukemia in order to timely prescribe drug therapy.

Purpose of the study To optimize the early detection of endothelial dysfunction and left ventricular myocardial contractility in patients with acute myeloid leukemia during chemotherapy treatment based on a comprehensive assessment of instrumental and laboratory research parameters.

Expected results Based on a comprehensive analysis using laser Doppler flowmetry, stress echocardiography with the determination of global longitudinal strain of the myocardium, biochemical markers of endothelial damage and cardiac biomarkers, a correlation between violations of the contractility of the left ventricular myocardium and violations of the vasoregulatory function of the vascular endothelium will be revealed, which will allow developing an algorithm for early detection of cardiomyopathy and vascular complications in patients with acute myeloid leukemia during chemotherapy treatment.

Detailed Description

Acute myeloid leukemia (AML) is a clonal neoplastic disease of the hematopoietic tissue associated with a mutation in the precursor cell of hematopoiesis, which results in a differentiation block and uncontrolled proliferation of immature myeloid cells.

It is believed that AML affects an average of 3-5 people per 100,000 people per year. At the same time, the incidence increases sharply at the age of over 60 years and amounts to 12-13 cases per 100 thousand of the population in people over the age of 80 years. The median age of this disease is 65 years. With a population of 140 million inhabitants in Russia, the estimated incidence rate (according to European and American researchers) should be about 5 thousand cases.

Anthracycline antibiotics have been an integral part of the treatment of acute myeloid leukemia since the 1970s. Anthracycline is usually given for 3 days (eg, daunorubicin 45-90 mg/m 2 daily, idarubicin 12 mg/m 2 daily) in combination with cytarabine (100-200 mg/m 2 daily) continuously for 7 days ) ("7+3" mode). Anthracyclines block the synthesis of DNA and RNA by inhibiting the enzyme topoisomerase IIβ and mitochondrial topoisomerase I. The subsequent disruption of DNA replication and transcription prevents the proliferation of rapidly dividing cells. In addition, anthracyclines damage DNA, proteins, and cell membranes by creating free oxygen radicals.

The clinical usefulness of anthracyclines is limited primarily by the high incidence of cardiotoxicity. According to the European Society of Cardiology guidelines for cardio- oncology, cardiovascular toxicity is defined as any impairment of cardiac function associated with anticancer treatment, as the term encompasses both a wide range of possible clinical manifestations and an etiological relationship with various treatments, including chemotherapy, radiation therapy, immunotherapy and treatment with targeted drugs. Cardiovascular toxicity can be acute, subacute or delayed, manifesting many years after chemotherapy or radiation therapy, involving a number of cardiac structures, which can lead to the development of heart failure, coronary heart disease, valvular heart disease, arrhythmias, including cardiac conduction disorders, and diseases of the pericardium.

Anthracycline-induced cardiotoxicity is the negative effect of anthracyclines on normal cardiac activity due to their toxic effects on the heart muscle and the cardiac conduction system. It is believed to be mediated in part by reactive oxygen species generated by anthracycline treatment, which leads to lipid peroxidation and DNA damage in cardiomyocytes. Other putative causes of anthracycline-induced cardiotoxicity include accumulation of cardiotoxic anthracycline metabolites in the heart, disruption of calcium homeostasis, mitochondrial damage, and induction of apoptosis.

Anthracycline-induced cardiotoxicity manifests as asymptomatic left ventricular dysfunction in 57% of treated patients and restrictive or dilated cardiomyopathy leading to congestive heart failure (CHF) in 16% to 20% of patients. Anthracycline-induced congestive heart failure is often resistant to therapy and has a mortality rate of up to 79%. Thus, there is a need for early detection of cardiovascular dysfunction associated with chemotherapy treatment of acute myeloid leukemia in order to timely prescribe drug therapy.

Purpose of the study To optimize the early detection of endothelial dysfunction and left ventricular myocardial contractility in patients with acute myeloid leukemia during chemotherapy treatment based on a comprehensive assessment of instrumental and laboratory research parameters.

Research objectives

1. To assess the state of endothelial function in patients with acute myeloid leukemia receiving chemotherapy based on a comprehensive assessment, including laser Doppler flowmetry and biochemical markers of endothelial damage (endothelin-1, asymmetric dimethylarginine).
2. To characterize the contractility of the left ventricular myocardium in patients with acute myeloid leukemia during chemotherapeutic treatment based on the indicators of stress echocardiography with the determination of global longitudinal deformation of the myocardium, as well as to assess the presence of myocardial damage by determining the level of highly sensitive troponin and brain natriuretic peptide.
3. To study the relationship between dynamic indicators of microcirculation, determined by laser Doppler flowmetry, with indicators of contractility of the left ventricular myocardium, detected using stress echocardiography with the determination of global longitudinal deformation of the myocardium, and the results of laboratory methods for assessing the function of the endothelium and myocardium.
4. To determine the frequency of development of various phenotypes of cardiovascular toxicity.
5. To identify the most significant prognostic criteria for the development of cardiotoxicity in patients with acute myeloid leukemia receiving chemotherapy.

Scientific novelty

1. For the first time, an algorithm for early detection of endothelial dysfunction and left ventricular myocardial contractility in patients with acute myeloid leukemia during chemotherapy treatment will be developed.
2. For the first time, the vasoregulatory function of the endothelium and the contractility of the left ventricular myocardium in patients with acute myeloid leukemia receiving chemotherapy will be studied based on a comprehensive assessment using laser Doppler flowmetry, stress echocardiography with the determination of global longitudinal deformation of the myocardium, biochemical markers of endothelial damage and cardiac biomarkers.

Practical significance It is planned to develop an algorithm for early detection of endothelial dysfunction and left ventricular myocardial contractility in patients with acute myeloid leukemia during chemotherapy treatment based on a comprehensive assessment using laser Doppler flowmetry, stress echocardiography with the determination of global longitudinal myocardial strain, biochemical markers of endothelial damage and cardiac biomarkers. .

Expected results Based on a comprehensive analysis using laser Doppler flowmetry, stress echocardiography with the determination of global longitudinal strain of the myocardium, biochemical markers of endothelial damage and cardiac biomarkers, a correlation between violations of the contractility of the left ventricular myocardium and violations of the vasoregulatory function of the vascular endothelium will be revealed, which will allow developing an algorithm for early detection of cardiomyopathy and vascular complications in patients with acute myeloid leukemia during chemotherapy treatment.

Research hypothesis:
