Despite the presence of various signs of cardiac amyloidosis ("red flags"), the introduction into routine practice of new non-invasive diagnostic methods (Speckle Tracking technology using echocardiography, myocardial scintigraphy with technetium pyrophosphate, genetic testing, screening for free light chains of immunoglobulins to exclude AL-amyloidosis), which have high specificity and sensitivity, transthyretinic (ATTR) cardiomyopathy is still a difficult to diagnose disease, especially in the early stages when treatment is most effective. The article presents a clinical case of ATTR-amyloidosis with predominant heart damage, manifested by severe diastolic heart failure resistant to treatment. ⋯ Despite the presence of cardiac and extracardial "red flags" of ATTR-amyloidosis in the patient, the diagnosis was established at autopsy. The paper analyzes possible errors of early diagnosis at the outpatient and inpatient stages of patient management.

To evaluate the efficacy and safety of the advanced technique for positioning the endocardial electrodes of a cardiac contractility modulation (CCM) device. ⋯ At the preoperative stage, it is recommended to perform a synchronized single-photon emission computed tomography of the myocardium with 99mTc-methoxy-isobutyl-isonitrile at rest before implantation of the CCM device to assess the presence of scar zones/myocardial fibrosis in the anterior and inferior septal regions of the interventricular septum of the left ventricle, followed by implantation of ventricular electrodes in the zone of the minor scar/fibrous lesion, which will allow to achieve optimal stimulation parameters, increase the effectiveness of CCM therapy, reduce the radiation exposure on medical personnel and the patient during surgery.

The understanding of the nature of catecholamine-secreting tumors has changed significantly in recent years, affecting terminology and classification. Phaeochromocytoma/paraganglioma (PCC/PG) is a rare neuroendocrine tumor from chromaffin tissue that produces and secretes catecholamines. ⋯ However, delayed diagnosis of PCC/PG is associated with a high risk of cardiovascular complications and a high mortality rate. The consensus presents the clinical manifestations of the disease with an emphasis on the course of arterial hypertension as the most common symptom in PCC/PG; modern ideas about the features of diagnosis, aspects of preoperative preparation, treatment, and follow-up of patients with PCC/PG are considered.

To evaluate the impact of a decrease in glomerular filtration rate (GFR) on the prognosis of patients with chronic heart failure (CHF), to analyze real clinical practice regarding the frequency of prescribing pathogenetic therapy for CHF, achieving target dosages depending on the gradation of GFR in patients included in the CHF Register of the Tyumen region. ⋯ GFR<60 ml/min/1.73 m2 occurs in every 3 patients with CHF across the entire range of LVEF. A decrease in GFR worsens the prognosis of patients with both HFrEF and HFpEF, increasing in direct proportion with the severity of the stage of CKD. Inclusion of patients in the monitoring program within the framework of the CHF service allows the treatment to be significantly brought closer to optimal drug therapy, at the same time, certain efforts are required to overcome difficulties with titration to target dosages.

The article discusses the causes and course of the last illness of I. S. ⋯ The primary disease that caused Turgenev's death is myxosarcoma (one of the sarcoma variants), involving soft tissues and thoracic vertebrae. The article presents data and discusses alternative diagnostic versions about the nature of the disease and the causes of death of the great Russian writer.
