Phenotype of a modern patient with valvular heart diseases: literature review

In modern conditions, valvular heart diseases (VHD) are one of the most common pathologies among cardiovascular diseases with a dynamic change in the phenotype of patients. An increase in the prevalence of VHD is currently observed due to the active implementation of diagnostic methods in cardiology. Geographical differences in the genesis of the development of valvular heart defects are noted, and the portrait of patients also changes as a result of aging and the addition of comorbid pathology. The purpose of the literature review was to present current trends in changing phenotype of patients with VHD, to study current data on the epidemiology of valve pathology, the contribution of various cardiovascular risk factors and comorbidity of patients on the course of the disease. Current data on the number of surgical interventions performed for VHD based on Russian, European, American, Australian and other studies, data on patient survival and mortality, as well as differences in these indicators in age groups of different countries are presented. The review will be useful for doctors to understand the modern portrait of a patient with VHD, trends in cardiovascular risk factors that influence the course of the disease and prognosis in patients with VHD

New biological markers for a prognostic model for assessing the risk of cardiac fibrosis in patients with ST-segment elevation myocardial infarction

HighlightsThe developed prognostic model for assessing the risk of cardiac fibrosis in patients with STEMI with HFmrEF and HFpEF is promising from the point of view of scientific and clinical potential because similar models for predicting the risk of cardiac fibrosis in patients with index MI are not currently validated. The developed scale includes such parameters as age, LVEF, COL-1, BMI, MMP-2. The scale can be used in patients with HFmrEF and HFpEF phenotypes. Identification of patients at high risk of myocardial fibrosis will allow choosing the appropriate treatment method. Aim. To develop a prognostic model for assessing the risk of cardiac fibrosis (CF) in patients with preserved left ventricular ejection fraction (HFpEF) and mildly reduced ejection fraction (HFmrEF) a year after ST-segment elevation myocardial infarction (STEMI) based on clinical, instrumental and biochemical data.Methods. The prospective cohort study included 100 STEMI patients with HFmrEF (LVEF 40–49%) and with HFpEF (50% or more). Echo was performed in all patients on the 1st, 10–12th day and a year after onset of STEMI. Upon admission to the hospital and on the 10–12th day after the onset of the disease, the following serum biomarker levels were determined: those associated with changes in the extracellular matrix; with remodeling and fibrosis; with inflammation, and with neurohormonal activation. At the 1-year follow-up visit, 84 patients underwent contrast-enhanced MRI to assess fibrotic tissue percentage relative to healthy myocardium.Results. The distribution of patients by HFmrEF and HFpEF phenotypes during follow-up was as follows: HFmrEF on the 1st day – 27%, 10th day – 12%, after a year – 11%; HFpEF on the 1st day – 73%, 10th day – 88%, after a year – 89%. According to cardiac MRI at the follow-up visit (n = 84), the median distribution of fibrotic tissue percentage was 5 [1.5; 14]%. Subsequently, the threshold value of 5% was chosen for analysis: CF≥5% was found in 38 patients (the 1st group), whereas CF<5% was noted in 46 patients (the 2nd group). When analyzing the intergroup differences in biological marker concentrations in the in-patient setting and at the annual follow-up, it was determined that the most significant differences were associated with “ST-2” (1st day) that in the “CF≥5%” group was 11.4 ng/mL higher on average compared to the “CF<5%” group (p = 0.0422); “COL-1” (1st day) that in the “CF≥5%” group was 28112.3 pg/mL higher on average compared to the “CF<5%” group (p = 0.0020), and “NT-proBNP” (12th day) that in the “CF<5 %” group was 1.9 fmol/mL higher on average compared to the “CF≥5%” group (p = 0.0339). Certain factors (age, LVEF (12th day), collagen-1 (1st and 12th day), body mass index, matrix metalloproteinase-2 (12th day) were determined and included in the prognostic model for assessing the risk of CF a year after the STEMI (AUC ROC 0.90, Chi-square test <0.0001).Conclusion. Prognostic model (scale) based on factors such as age, left ventricular ejection fraction (12th day), collagen-1 (1st and 12th day), body mass index, matrix metalloproteinase-2 (12th day) shows high prognostic power and enables identification of patients with HFmrEF and HFpEF phenotypes and at high risk of cardiac fibrosis a year after STEMI

КЛИНИЧЕСКИЙ СЛУЧАЙ ВЕДЕНИЯ ПАЦИЕНТА С ЭКСТРЕМАЛЬНОЙ ГИПЕРТРОФИЧЕСКОЙ КАРДИОМИОПАТИЕЙ И РЕЦИДИВИРУЮЩИМ ИДИОПАТИЧЕСКИМ ГИДРОПЕРИКАРДОМ

HighlightsWe report a case of a patient with extreme hypertrophic cardiomyopathy and complex cardiac pathology undergoing heart transplantation. The article will be useful for cardiologists, therapists and cardiovascular surgeons. AbstractWe present a case of a patient with extreme hypertrophic cardiomyopathy, Wolff–Parkinson–White syndrome and nonspecific chronic exudative pericardial effusion with recurrent idiopathic transudative pericardial effusion. This case involves several approaches to treatment – medication and surgery for treating a patient with combined cardiomyopathy and pericardial effusion, which served as a “bridge” for a later change inro radical treatment - orthotopic heart transplantation.Основные положенияОписан редкий случай экстремальной гипертрофической кардиомиопатии у пациента с комплексной кардиологической патологией, особенности ведения которого позволили дождаться этапа радикального хирургического лечения в виде трансплантации сердца. Статья будет полезна кардиологам, терапевтам и сердечно-сосудистым хирургам. РезюмеВ рамках клинического случая представлен портрет пациента с экстремальной гипертрофической кардиомиопатией, синдромом Вольфа – Паркинсона – Уайта и неспецифическим хроническим экссудативным перикардитом с рецидивирующим гидроперикардом идиопатического генеза. Данный случай актуален комплексным подходом – выбором как медикаментозного, так и интервенционного, хирургического способов лечения пациента с сочетанной кардиологической патологией, которые явились «мостом» для радикального лечения в виде ортотопической трансплантации сердца.
