The development of different phenotypes of coronary artery (CA) lesions is regulated via many various factors, such as pro-inflammatory agents, zinc-dependent endopeptidases, growth factors and circulating microRNAs (miRs). To evaluate the expression levels of miR-34a, miR-145 and miR-222, tumor necrosis factor α (TNF-α), matrix metalloproteinases (MMP-1, -9, -13 and -14) and vascular endothelial growth factor (VEGF) in patients with different phenotypes of coronary artery disease (CAD): ischemia/angina with non-obstructive coronary arteries (INOCA/ANOCA) and obstructive CAD (oCAD) compared with a control group. This cross-sectional observational study included 157 subjects with a verified CAD diagnosis (51 patients with INOCA, 76 patients with oCAD and 30 healthy volunteers).

Article Synopsis
  • This study aimed to identify specific metabolomic and structural markers related to left ventricular (LV) remodeling in patients with chronic heart failure (CHF) caused by ischemia and a low ejection fraction (EF).
  • The research involved comparing 56 CHF patients with 50 control patients, measuring various amino acids and acylcarnitines, alongside echocardiographic assessments over 6 months.
  • Results showed that CHF patients had lower levels of certain amino acids and higher levels of acylcarnitines, with specific markers significantly influencing long-term LV remodeling outcomes.

Article Synopsis
  • The study aimed to identify why patients with chronic heart failure (CHF) in Russia have a poor prognosis, using data from various population samples and medical records over several years.
  • It established the prevalence of CHF in the Russian population, finding that 8.2% of individuals meet soft criteria for CHF, while 3.1% met strict criteria, with significant influences from conditions like hypertension and ischemic heart disease.
  • The prognosis for these patients is grim, with over half dying within four years after acute decompensated heart failure (ADHF), and most patients with severe CHF not surviving beyond ten years, primarily due to inadequate medication use and poor patient follow-up.

Article Synopsis
  • The CHANCE study investigated the effects of a monitoring and education program for patients with chronic heart failure, comparing an intervention group (IG) receiving structured support to a control group (CG) receiving standard care.
  • Results showed that the IG had significantly lower mortality rates (8.3%) compared to the CG (13.0%), and a relative risk of 0.68 for death, indicating the program's effectiveness in saving lives.
  • Additionally, the IG exhibited better improvements in clinical condition, functional capabilities (as seen in the 6-minute walk test), and overall quality of life, with significant reductions in anxiety and depressive symptoms over 12 months.

Aim: To discuss two aspects that can be used to improve the adherence to therapy in patients with arterial hypertension (AH): 1) which of the angiotensin II receptor blockers (ARBs) provides the highest adherence rates; 2) how various factors influence adherence rates.

Material And Methods: An analysis of one of the world's largest clinical practice databases, Truven Health Analytics MarketScan (currently Merative MarketScan), was performed. The analysis included data on patients of both sexes aged 30 to 65 years who had been diagnosed with uncomplicated AH (at least once between March 1, 2012 and January 1, 2018) and prescribed monotherapy with one of ARBs.

Article Synopsis
  • The study aimed to examine the effects of polychemotherapy on cardiovascular biomarkers in 30 patients with newly diagnosed lymphomas, focusing on cardiotoxicity and heart function changes over six months.
  • Significant changes were observed in systemic inflammation markers, with C-reactive protein (CRP) and interleukin-6 (IL-6) levels decreasing, while biomarkers like endothelin-1 (ET-1) and ST-2 showed increases that were not statistically significant.
  • Despite alterations in diastolic heart function, there were no signs of cardiotoxicity affecting heart muscle contraction, suggesting that polychemotherapy did not adversely impact the patients' systolic function.

The most important component of cardio-oncology is the assessment of the risk of development and diagnosis of cardiovascular toxicity of the antitumor therapy, the detection of which is largely based on visualization of the cardiovascular system. The article addresses up-to-date methods of non-invasive visualization of the heart and blood vessels, according to the 2022 European Society of Cardiology Clinical Guidelines on cardio-oncology. Also, the article discusses promising cardiovascular imaging techniques that are not yet included in the guidelines: assessment of coronary calcium using multislice computed tomography and positron emission computed tomography with 18F-labeled 2-deoxy-2-fluoro-d-glucose.

Assessing the functional capacity and exercise tolerance is an important and widely used research tool in patients with heart failure. It is used not only in cardiac rehabilitation and physical therapy, but also for inclusion criteria and outcome measures in studies of drug interventions. This document outlines the scope, guidelines for the implementation and interpretation, and limitations of the methods for assessing the functional capacity and exercise tolerance in clinical trials in patients with heart failure.

Multiple myeloma (MM) is an incurable malignancy of clonal plasma cells. Various diagnostic methods are used in parallel to accurately determine stage and severity of the disease. Identifying a biomarker or a panel of biomarkers could enhance the quality of medical care that patients receive by adopting a more personalized approach.

Significant advances in timely diagnosis and modern antitumor therapy have led to a considerable increase in the survival rate of cancer patients. On the other hand, the incidence of cardiovascular (CV) diseases and their complications is increasingly growing, including due to side effects of anticancer drugs. CV complications are the most common cause of non-oncological death of cancer patients.

A 67-year-old woman was admitted to the Hematology Department in 2014 with complaints of weakness and a low-grade fever. After conducting various tests, it was confirmed that she had Waldenstrom macroglobulinemia. She underwent several rounds of chemotherapy and maintenance therapy with rituximab, which resulted in a good clinical response.

Background: Progressive myocardial remodeling (MR) in chronic heart failure (CHF) leads to aggravation of systolic dysfunction (SD) and clinical manifestations. Identification of metabolomic markers of these processes may help in the search for new therapeutic approaches aimed at achieving reversibility of MR and improving prognosis in patients with CHF.

Methods: To determine the relationship between plasma acylcarnitine (ACs) levels, MR parameters and clinical characteristics, in patients with CHF of ischemic etiology (n = 79) and patients with coronary heart disease CHD (n = 19) targeted analysis of 30 ACs was performed by flow injection analysis mass spectrometry.

Over the past few decades, due to the extensive implementation of cancer screening programs, up-to-date early diagnostic methods, and effective combinations of antitumor therapy, it has become possible to significantly improve survival of cancer patients. At the same time, despite the effective treatment of malignancies, most patient face adverse and often life-threatening effects of specific treatment on the heart and blood vessels. All this resulted in active development of a new field in cardiology, cardio-oncology.

Studying the key mechanisms of cardiovascular diseases has opened new possibilities for the pharmacological impact on the pathophysiological mechanisms of heart failure (HF). The signaling pathway, nitric oxide - soluble guanylate cyclase - cyclic guanosine monophosphate (NJ-sGC-cGMP), provides normal functioning of the cardiovascular system in healthy people and serves as a potential target for medicines in HF with reduced ejection fraction (HFrEF). In HFrEF progression, the sGC activity decreases due to endothelial dysfunction and oxidative stress.
