Article Synopsis
  • The study aimed to explore how metabolic disorders and obesity affect hemodynamic parameters in patients with chronic thromboembolic pulmonary hypertension (CTEPH) using data from the POLET registry.
  • The research analyzed various medical factors from 84 patients, including their metabolic profiles, functional capacity, and heart health metrics like right heart catheterization and echocardiography.
  • Findings revealed significant correlations between right atrial area and lipid levels, indicating that older patients with severe functional classes (mostly III and IV) may experience a greater impact from metabolic issues, which is crucial for assessing patient risk of death.

Background: Arterial hypertension (AH) remains the leading risk factor associated with cardiovascular diseases (CVDs), cerebrovascular disease and chronic kidney disease. About 70% of patients with AH who are on monotherapy cannot achieve blood pressure (BP) targets, and therefore all quidelines for the management of AH have recently recommended prescribing combination therapy (PCT). In real clinical practice (RCP), there remains significant uncertainty in the effectiveness and rationality of therapy, despite the wide availability of antihypertensive drugs (AHD) and the presence of recommendations for a stepwise approach to prescribing combinations of specific groups of AHD in different clinical situations.

Introduction: To identify predictors of excessive daytime sleepiness we analyzed data from the 'Epidemiology of cardiovascular diseases in regions of Russia (ESSE-RF)' study.

Methods: Data from participants of the cohort study ESSE-RF (2012-2013), aged 25-64 years, from 13 regions of Russia were analyzed (2012-2013). The participants were interviewed regarding their sleep complaints, including difficulties with initiating and maintaining sleep, sleepiness, and use of sleeping pills.

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. The incidence of PCC/PG is relatively low, with 2-8 cases per 1 million population per year; among patients with arterial hypertension, their prevalence is 0.

For patients with pulmonary hypertension (PH) there have been no recommendations for physical rehabilitation for a long time, and in fact physical activity was discouraged. Nowadays, the position regarding exercise in patients with PH has changed studies have shown the safety and effectiveness of exercise in these patients. Most of the studies published to date on rehabilitation in patients with PH have assessed its effect on exercise tolerance.

Introduction: Management of patients with acute coronary syndrome (ACS) is usually universal, regardless of gender, age, and ethnicity. But often in practice, gender and age influence medical decisions, and patients do not receive proper medical care. Medical care for patients with ACS was analyzed by gender according to the federal register of ACS data.

Aim: To assess the incidence of cardiovascular and cerebrovascular events in patients with controlled and uncontrolled hypertension, controlled resistant and uncontrolled resistant hypertension, refractory hypertension, and probably resistant and probably refractory hypertension.

Materials And Methods: A telephone call was made to 256 patients with hypertension included in the database to assess the incidence of cardiovascular and cerebrovascular diseases. All responding patients were divided into 7 groups according to the classification of hypertension based on the achievement/non-achievement of target blood pressure values and the number of drugs taken (controlled and uncontrolled hypertension, controlled resistant and uncontrolled resistant hypertension, refractory hypertension, and probably resistant and probably refractory hypertension).

Aim: To analyze therapy in patients with arterial hypertension (AH) in 20102020.

Materials And Methods: Data of hypertensive patients observed in primary health care, entered into the base of hypertension registry for 20102020 years in the whole group (n=44 653) and in a separate subgroup of hypertensive patients in the absence of: ischemic heart disease, a history of myocardial infarction, chronic heart failure (n=20 569).

Results: About 80% of hypertensive patients are patients of high and very high risks (from 2010 to 2020, the proportion of very high cardiovascular risk (CVR) increased from 18.

Pulmonary hypertension (PH) is a severe and often rapidly progressive disease with fatal outcome. Endothelial dysfunction in PH is associated with decreased nitric oxide production. After reviewing the mechanisms of action and the evidence base for specific therapy with phosphodiesterase 5 inhibitors (PDE-5) and soluble guanylate cyclase stimulators, a reseach review on switching from PDE-5 to riociguat is conducted.

In recent years, there has been an increase of patients with arterial hypertension, one of the variants of which is refractory arterial hypertension. This unfavorable clinical variant of the course of hypertension worries clinicians, due to the higher risk of developing cardiovascular complications, realizing the need for a better control of blood pressure. The presented clinical case demonstrates the successful combined treatment of refractory hypertension using antihypertensive therapy and renal denervation.

The diagnosis of resistant arterial hypertension allows us to single out a separate group of patients in whom it is necessary to use special diagnostic methods and approaches to treatment. Elimination of reversible factors leading to the development of resistant arterial hypertension, such as non-adherence to therapy, inappropriate therapy, secondary forms of arterial hypertension, leads to an improvement in the patient's prognosis. Most patients with resistant hypertension should be evaluated to rule out primary aldosteronism, renal artery stenosis, chronic kidney disease, and obstructive sleep apnea.

Obesity is an independent predictor of cardiovascular diseases (CVD), including heart failure (HF). Nevertheless, numerous studies have shown that patients with CVD who are overweight and slightly obese have a better short-term and moderate prognosis than thinner patients with CVD. This phenomenon has been called the obesity paradox.

On December 13, 2021, an expert council was held to determine the position of experts of different specialties regarding the reasons for the low level of diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) in real clinical practice in a pandemic of a new coronavirus infection and possible ways to improve detection in patients with pulmonary embolism (PE) ) in history. The reasons for the low level of diagnosis of CTEPH are the insufficient level of knowledge of specialists, especially primary care physicians; lack of clear regulatory documents and expert centers for the management of this category of patients. Primary diagnosis of CTEPH in a pandemic can be strengthened through the widespread use of telemedicine for consultations of primary care physicians with specialists from expert centers; to maximize the role of echocardiography and computed tomography (CT) as differential diagnostic tools for dyspnea, in particular in patients with COVID-19.
