[The Structure of Concomitant Pathology in Patients With Hypertrophic Cardiomyopathy in The Older Age Group. Review and Clinical Observations].

Abstract

Advances in modern drug and surgical treatment of patients with hypertrophic cardiomyopathy (HCM) have resulted in a significant increase in the life expectancy of these extremely severe patients. Therefore, in addition to the genetic markers, major neurohumoral systems and morpho-functional parameters of intracardiac hemodynamics, the course and prognosis of the disease are influenced by concomitant pathology. In infancy and early childhood, HCM is associated with tumors of chromaffin tissue of various localizations; however, the older the patient, the greater the likelihood of developing metabolic syndrome, secondary atherosclerosis and ischemic heart disease (IHD), and hypertension, which significantly complicates the verification of the HCM diagnosis. We have previously described cases of IHD secondary to HCM, which significantly affected the course and prognosis of both diseases. However, in old age, other comorbidities may also occur in addition to the diseases described above. Based on long-term observation of a large cohort of patients, this article analyzes a wide range of HCM combinations with pathology of other organs and systems, including malignant neoplasms, which makes significant adjustments to the treatment of both the underlying disease and cancer. The material is presented in the form of a brief review of literature on this topic and our own clinical observations and studies.
