Background Long-term secondary preventive programs in coronary heart disease (CHD) are of highest efficacy but numerous logistical problems often compromise their implementation. Contemporary remote technologies have a potential to overcome these barriers. Aim: To assess  the impact of 2 preventive counselling programs with subsequent remote support in CHD patients with concomitant obesity. Methods: A prospective randomized parallel-group study in 120 stable CHD patients hospitalized for elective coronary revascularization who were from 40 to 65 years old and had concomitant obesity. Patients were randomized (1:1:1) into 3 groups (n=40 each). Before discharge, Groups 1 and 2 received a single-session comprehensive counselling with focus on diet followed by remote counselling by phone (Group 1) or via text messages (Group 2). Remote counselling was delivered weekly (Months 1-3) and then monthly (Months 4-6). Group 3 received only standard advice from their attending physicians. The patients were followed for 12 months with assessment of adiposity measures, self-reported dietary patterns, physical activity (IPAQ questionnaire), smoking status, blood pressure (BP), fasting blood glucose, lipids and C-reactive protein (CRP) levels, as well as of clinical events. Results: At 1 year of follow-up, the patients from both intervention groups showed a marked improvement of several risk factors including obesity: the body mass index was reduced by 1.48±0.13 kg/m² in Group 1 and by 1.53±0.18 kg/m² in Group 2; the waist circumference went down by 7.62±0.49 and by 7.41±0.74 cm, respectively; the height-normalized fat mass decreased by 4.66±0.40 kg and 5.98±0.63 kg, respectively (all P values are <0.01 vs corresponding changes in the control group). These changes were coupled with more healthy dietary patterns and less sedentary lifestyles in both intervention groups: the proportion of patients with low activity level fell from 87.5% to 2.5% in Group 1 and from 80% to 10% in Group 2 (both p values <0.01 vs control). In Group 1, BP decreased by 18.08±2.20 mmHg (systolic) and 8.56±1.61 mmHg (diastolic); both р values <0.01 vs Group 3. In Group 2 systolic BP dropped by only 11.95±2.50 mmHg (non-significant) and diastolic BP by 6.33±1.52 mmHg (р<0.05 vs control). The proportion of smokers went down from 30% to 5% in Group 1 and from 22.5% to 0% in Group 2 (both p values <0.01 vs control). The fasting glucose levels decreased by 0.21±0.20 mmol/L in Group 1 and by 0.48±0.25 mmol/L in Group 2 (<0.01 vs control, both), but there were no meaningful improvements in blood lipids or CRP. Conclusion: Long-term (6 months) secondary prevention programs incorporating remote support technologies result into sustained improvement of key secondary prevention indicators in obese CHD patients, irrespective of the support modality (by phone or via electronic messaging).

Aim. To comparatively analyze the clinical efficiency of eradiation therapy (ET) in patients with coronary heart disease (CHD) concurrent with gastroduodenal pathology (GDP). Subjects and methods. The study was conducted in three steps. In Step 1, 1588 patients with chronic CHD were examined. In Step 2, the characteristics of the course of CHD concurrent with Helicobacter pylori-associated GDP in 147 patients with these conditions compared to the same number of CHD patients without GDP. In Step 3, the impact of a GDP treatment option on the efficiency of treatment was investigated in the patients with CHD. Group 1 received ET + basic therapy (BT); Group 2 used antisecretory therapy + BT; Group 3 consisted of CHD patients without concomitant GDP who received BT only. The time course of changes in clinical and quality-of-life (QOL) indicators was assessed. Results. The patients with CHD concurrent with GDP have a more severe course of the disease as manifested by deterioration in clinical status and QOL. After ET, anginal attack rates were decreased by 62.6% in Group 1, by 30.7% in Group 2 (during antisecretory therapy), and by 29.5% in Group 3. The level of physical QOL increased by 23.7% in Group 1, which was not observed in Groups 2 and 3. Conclusion. Inclusion of ET in an algorithm for treating CHD patients with GDP promotes the angina stability and normalizes QOL in the patients.

The aim – to study the dynamics of the level of interleukin-6 (IL-6) under various drugs for analgesic sedation in the perioperative period of planned coronary stenting. Materials and methods. This study was conducted from September 2018 to March 2020 in 90 patients with coronary heart disease. Patients were evenly divided into three study groups, depending on the drugs that were used for intraoperative analgosedation. Group 1 – slow intravenous administration of 10 mg of diazepam solution and 100 μg of fentanyl solution for induction and repeated administration of these drugs in the same dose to maintain anesthesia during surgery; group 2 – slow intravenous administration of the solution of fentanyl 1.5 mg/kg per induction and 1.5 mg/kg for 1 h to maintain analgesia, propofol solution was used to maintain a certain level of sedation; group 3 – slow intravenous administration of 1 mg/kg of lidocaine solution for induction, for sedation – propofol solution as well. All patients underwent recanalization as planned. In our study, the main study parameter was the level of IL-6 at the beginning of surgery and 10 minutes after stent implantation. Results. When comparing operational indicators with the results that were obtained after stenting, in all groups, IL-6 indicators were lower than preoperative ones. The statistically significant difference between the studied index before surgery and 10 min after stent implantation was in the groups 2 and 3, in contrast to that in patients of the group 1: the level of IL-6 decreased to 30 % in group 2 (p = 0.005) and in group 3 (p = 0.001). Conclusions. The level of pro-inflammatory IL-6 in routine coronary artery stenting tends to decrease after stent placement, with lower rates under propofol solution usage as an anesthetic. At the same time, in group 3 (where nonopioid analgesia was used) the level of interleukin-6 at point 10 min after stent implantation was significantly lower than in first group. This fact might be explained by usage of lidocaine solution in patients of the third group. Key words: interleukin-6, planned coronary stenting, analgosedation, coronary heart disease.

Objectives:To examine bone mineral density (BMD) in men with coronary heart disease (CHD), depending on the state of the muscle mass, strength and function.Methods:79 men aged over 50 years with verified CHD were examined (mean age 63 (57; 66) years).The BMD and T-criterion (standart deviation, SD) of the femoral neck and lumbar spine (L1-L4) were evaluated using dual-energy x-ray absorptiometry (DXA) on the Lunar Prodigy Primo bone densitometer (USA). The following reference intervals were used: normal BMD values (T-criterion ≥-1), osteopenia (OPe) (T-criterion from -1 to -2.5), and osteoporosis (OP) (T-criterion <-2.5).To assess muscle mass, the total area (cm2) of the lumbar muscles of the axial section at the level of the 3rd lumbar vertebra (L3) was determined using multispiral computed tomography on a 64-slice computer tomograph “Somatom Sensation 64” (Siemens AG Medical Solution, Germany). The ratio of the obtained index of the area of skeletal muscle to the square of the patient’s growth index determined the “ skeletalmuscular index L3” (SMI). The media considered the threshold value to be 52.4 cm2/m2.Results:The femoral neck BMD in the examined patients was 0.96 (0.89; 1.03) g/cm2, which corresponds to -0.50 (-1.00; 0) SD according to the T-criterion, in the lumbar spine -1.23 (1.11; 1.32) g/cm2and 0.4 (-0.50; 1.20) SD according to the T-criterion.In accordance with the recommendations of the European working group on sarcopenia in Older people (EWGSOP, 2010, 2018), the patients were divided into 3 groups: 31 patients without sarcopenia (group 1), 21 patients with isolated muscle loss (presarcopenia) (group 2) and 27 patients with sarcopenia (group 3).BMD in the femoral neck in the group of patients without sarcopenia was 0.96 (0.72; 1.26) g/cm2, which corresponds to -0.50 (-0.8; 0.2) SD according to the T-criterion, in the lumbar spine – 1.19 (1.10; 1.275) g/cm2and 0.1 (-0.6; 0.8) SD according to the T-criterion. BMD in the femoral neck in the group of patients with presarcopenia (group 2) – 0.995 (0.94; 1.04) g/cm2and -0.3 (-0.70; 0) SD according to the T-criterion, in the lumbar spine – 1.32 (1.24; 1.40) g/cm2and 1.20 (0.50; 1.90) SD according to the T-criterion. In patients with established sarcopenia (group 3), the following indicators of BMD and T-criterion were recorded: 0.95 (0.845; 0.98) g/cm2and -0.60 (-1.40; -0.40) SD and 1.23 (0.085; 1.31) g/cm2and 0.4 (-0.8; 1.1) SD in the femoral neck and lumbar spine, respectively.A comparative analysis of the results of the DXA found that patients with sarcopenia had a significant decrease in the BMD and T-criterion in the femoral neck compared to patients with presarcopenia (p=0.039 and p=0.040, respectively). There were no differences between the groups of patients without sarcopenia and with sarcopenia and presarcopenia (p>0.05).It was found that patients with sarcopenia had significantly lower BMD and T-criterion in the lumbar spine compared to patients with presarcopenia (p=0.017 and p=0.0165, respectively). The values of the BMD and T-criterion in the groups of patients without sarcopenia and with presarcopenia and sarcopenia in the lumbar spine were comparable (p>0.05).Conclusion:The presence of sarcopenia is associated with loss of BMD in the femoral neck and in the lumbar spine. The results obtained confirm the high probability of common pathogenetic links between OP and sarcopenia.Disclosure of Interests:None declared

Abstract OBJECTIVES Chronic kidney disease (CKD) is prevalent in patients undergoing cardiovascular surgery, and it negatively impacts procedural outcomes; however, its influence on the outcomes of aortic surgery has not been well studied. This study aims to elucidate the importance of CKD on the outcomes of aortic root replacement (ARR). METHODS Patients who underwent ARR between 2005 and 2019 were retrospectively reviewed (n = 882). Patients were divided into 3 groups based on the Kidney Disease: Improving Global Outcomes criteria: Group 1 [estimated glomerular filtration rate (eGFR) ≥ 60 ml/min/1.73 m2, n = 421); Group 2 (eGFR = 30–59 ml/min/1.73 m2, n = 424); and Group 3 (eGFR &lt; 30 ml/min/1.73 m2, n = 37). To reduce potential confounding, a propensity score matching was also performed between Group 1 and the combined group of Group 2 and Group 3. The primary end point was 10-year survival. Secondary end points were in-hospital mortality and perioperative morbidity. RESULTS Severe CKD patients presented with more advanced overall chronic and acute illnesses. Kaplan–Meier analysis showed a significant correlation between CKD stage and 10-year survival (log-rank P &lt; 0.001). The number of events for Group 1 was 15, Group 2 was 49 and Group 3 was 11 in 10 years. Group 3 had significantly higher in-hospital mortality (13.5% vs 3.5% in Group 2 vs 0.7% in Group 1, P &lt; 0.001) and stroke (8.1% vs 7.1% vs 1.2%, P &lt; 0.001) as well as introduction to new dialysis (27.0% vs 5.4% vs 1.7%, P &lt; 0.001). eGFR was shown to be an independent predictor of mortality (hazard ratio, 0.98; 95% confidence interval, 0.96–0.99). Comparison between propensity matched groups showed similar postoperative outcomes, and eGFR was still identified as a predictor of mortality (hazard ratio, 0.97; 95% confidence interval, 0.95–0.99). CONCLUSIONS Higher stage in CKD negatively impacts the long-term survival in patients who are undergoing ARR.

To determine an effective nutritional regimen for management of growth failure in infants with congenital heart disease and congestive heart failure, the authors studied 19 infants with cardiac anomalies who were not candidates for early corrective surgery. Patients were randomly assigned to one of three feeding groups: group 1 (n = 7) received continuous, 24-hour nasogastric alimentation; group 2 (n = 5) received overnight, 12-hour nasogastric infusions plus daytime oral feedings as tolerated; and group 3 (n = 7) received oral feedings alone. For all patients, commercial infant formula (cow's milk or soy protein) was supplemented to a calorie density of approximately 1 kcal/mL. During a 5.25 ± 0.45 month study period, only group 1 infants achieved intakes &gt; 140 kcal/kg per day (mean = 147 kcal). Serial anthropometric measurements demonstrated that only 24-hour infusions (group 1) were associated with significantly improved nutritional status, when assessed by z scores for weight (P &lt; .01) and length (P &lt; .05). Group 1 infants also showed marked increases in midarm muscle circumference and triceps and subscapular skinfold thicknesses (P &lt; .01, compared with groups 2 and 3). These data suggest that infants with congenital cardiac defects complicated by malnutrition manifest increased nutrient requirements for growth and weight gain. Continuous, 24-hour, nasogastric alimentation is a safe and effective method for achieving both increased nutrient intake and improved overall nutritional status in these infants.

Background Full secondary prevention medication regimen is often under-prescribed after acute myocardial infarction. Design The purpose of this study was to analyse the relationship between prescription of appropriate secondary prevention treatment at discharge and long-term clinical outcomes according to risk level defined by the Thrombolysis In Myocardial Infarction (TIMI) Risk Score for Secondary Prevention (TRS-2P) after acute myocardial infarction. Methods We used data from the 2010 French Registry of Acute ST-Elevation or non-ST-elevation Myocardial Infarction (FAST-MI) registry, including 4169 consecutive acute myocardial infarction patients admitted to cardiac intensive care units in France. Level of risk was stratified in three groups using the TRS-2P score: group 1 (low-risk; TRS-2P=0/1); group 2 (intermediate-risk; TRS-2P=2); and group 3 (high-risk; TRS-2P≥3). Appropriate secondary prevention treatment was defined according to the latest guidelines (dual antiplatelet therapy and moderate/high dose statins for all; new-P2Y12 inhibitors, angiotensin-converting-enzyme inhibitor/angiotensin-receptor-blockers and beta-blockers as indicated). Results Prevalence of groups 1, 2 and 3 was 46%, 25% and 29% respectively. Appropriate secondary prevention treatment at discharge was used in 39.5%, 37% and 28% of each group, respectively. After multivariate adjustment, evidence-based treatments at discharge were associated with lower rates of major adverse cardiovascular events (death, re-myocardial infarction or stroke) at five years especially in high-risk patients: hazard ratio = 0.82 (95% confidence interval: 0.59–1.12, p = 0.21) in group 1, 0.74 (0.54–1.01; p = 0.06) in group 2, and 0.64 (0.52–0.79, p < 0.001) in group 3. Conclusions Use of appropriate secondary prevention treatment at discharge was inversely correlated with patient risk. The increased hazard related to lack of prescription of recommended medications was much larger in high-risk patients. Specific efforts should be directed at better prescription of recommended treatment, particularly in high-risk patients.

Abstract Introduction Juvenile rheumatic heart disease (RHD) refers to RHD in patients &lt;20 years of age. There are no contemporary data highlighting the differences between juvenile and older RHD patients. Purpose We aim to report the age related differences in the pattern, and consequencies of valvular dysfunction in patients of RHD. Methods The 2475 consecutive patients of RHD diagnosed using clinical and echocardiographic criteria were registered prospectively from 2011 till December 2019. Patients were divided into 3 groups according to their age: Group 1 (Juvenile RHD), Group 2 (21–50 years), and Group 2 (&gt;51 years).The data concerning the socio-demographic and clinical profile were recorded systematically, and the nature and severity of valvular dysfunction was assessed by echocardiography. The data were analyzed using the Epi-InfoTM Software. Results Out of 2475 RHD patients, Juvenile RHD comprised of 211 (8.5%) patients. Group 2 and 3 comprised of 1691 (68.3%) and 573 (23.2%) patients respectively. Overall, 1767 (71.4%) patients were females, however this female predilection was less pronounced in juvenile RHD (55.5% females vs 44.5% males) as compared to older groups. Past history of acute rheumatic fever was more commonly recorded in Juvenile RHD group (37.9% vs 18.8% in group 2 and 10% in group 3, p=0.0001). At the time of registration, the presence of advanced heart failure symptoms (dyspnea class III and IV) (11.4% group 1 vs 13.9% group 2 vs 20.6% group 3, p&lt;0.0001), right heart failure symptoms (0.9% group 1 vs 2.5% group 2 vs 7.3% group 3, p&lt;0.01), thromboembolic events (0% group 1 vs 4.1% group 2 vs 3.3% group 3, p&lt;0.01), atrial fibrillation (2.8% group 1 vs 24.5% group 2 vs 45.9% group 3, p&lt;0.0001), and pulmonary hypertension (27.1% group 1 vs 40.3% group 2 vs 51.9% group 3, p&lt;0.01), were all more commonly recorded in non-juvenile older RHD groups. Multivalvular involvement was also less common in juvenile RHD (34.6% vs 42.4% and 44.5%, p=0.04). Mitral regurgitation was the most common lesion in Juvenile RHD followed by aortic regurgitation (68.7% and 40.2% respectively). Stenotic lesions (both mitral and aortic) were present more commonly in older age groups. Conclusion RHD is predominantly a disease of females, however the predilection is less common in juvenile patients. Juvenile RHD predominantly affects the mitral valve and mainly leads to regurgitant lesions. As the age advances, the complications of RHD, mainly heart failure symptoms, thromboembolic events, pulmonary hypertension, and atrial fibrillation, become more common.

Background: Pulmonary arterial hypertension (PAH) is a common complication of congenital heart disease (CHD) with uncorrected left-to-right shunts. Currently, no consensus guideline exists on the management of PAH-CHD in children, especially those who do not meet operability criteria. Objective: To compare survival between three groups of high-risk PAH-CHD, group 1: total correction including both surgical and percutaneous intervention, group 2: palliative treatment, and group 3: conservative with medical treatment group. Materials and Methods: All pediatric patients with PAH-CHD that underwent cardiac catheterization between January 1, 2008 and December 31, 2017 were retrospectively reviewed. Inclusion criteria were high risk PAH-CHD patients who had pulmonary vascular resistance (PVR) greater than 6 Wood unit·m² and PVR-to-SVR ratio greater than 0.3 evaluated in room air. Exclusion criteria were younger than three months of age, severe left side heart disease with pulmonary capillary wedge pressure greater than 15 mmHg, obstructive total pulmonary venous return, and single ventricle physiology. The Kaplan-Meier analysis was performed from the date of PAH diagnosis to the date of all-cause mortality or to censored date at last follow-up. Results: Seventy-six patients with a median age at diagnosis of 27.5 months (IQR 14.5 to 69.0 months) were included in this study. The patients were divided into three subgroups and included 38 patients (50.0%) in group 1, six patients (7.9%) in group 2, and 32 patients (42.1%) in group 3. The median follow-up time was 554 days (IQR 103 to 2,133 days). The overall mortality was 21.7%. One-year survival in patients with simple lesion in group 1 and 3 were 79.5% and 87.5% and patients with complex lesions in group 1, 2, and 3 were 93.8%, 83.3%, and 73.1%, respectively. The results showed that most mortalities occurred in the first year. There were no statistically significant differences in survival among difference types of treatment (log rank test, p=0.522). Conclusion: The mortality of high-risk PAH-CHD patients were not different among those who underwent corrective surgery, palliative, or conservative treatment. The mortality was high in the first year after PAH diagnosis and remain stable afterward. Management decision for an individual with high-risk PAH-CHD patients requires comprehensive clinical assessment to balance the risks and benefits before making individualized clinical judgment.

Introduction: Preserved function of collecting duct is essential for the response to tolvaptan (TLV), and urinary level of aquaporin 2 (U-AQP2) can be a marker for vasopressin-dependent activity of collecting duct. Hypothesis: Higher levels of U-AQP2 in proportion to plasma levels of vasopressin (P-AVP) may be associated with better initial responses to TLV and eventually result in the improved prognosis after long-term treatment of TLV. Methods: Consecutive 60 in-hospital patients with stage D heart failure (HF) who received TLV on a de novo basis were enrolled during 2011-2013. We also selected 60 HF patients by propensity score matching who were hospitalized during the same period but never treated with TLV. Events were defined as death and/or HF re-hospitalization. Results: TLV (3.75-15 mg/day) was continuously administered except death or ventricular assist device implantation occurred. There were 41 patients (group 1) who had increases in UV over the first 24 h after TLV initiation, and all of them had U-AQP2/P-AVP ≥0.5 х103 with higher U-AQP2 levels (5.42 ± 3.54 ng/mL) before TLV treatment. On the other hand, UV rather decreased even after TLV initiation in 19 patients over the first 24 h (group 2). Those in the group 2 universally had U-AQP2/P-AVP <0.5 х103, extremely low U-AQP2 levels (0.76 ± 0.59 ng/mL, p<0.001 vs. group 1), and similar P-AVP with the group 1 at baseline. The 41 and 19 patients without TLV treatment (group 3 and 4) were respectively matched to the group 1 and 2 by propensity scores. Interestingly, every patient in the group 3 had U-AQP2/P-AVP ≥0.5 х103, and vice versa in the group 4. Among the four groups, congestion-related symptoms were only improved in the group 1 after 1 month of enrollment. The patients in the group 1 had significantly better event-free survival over 2-year by TLV treatment compared with the group 3 (76% vs. 43%, p<0.014). In contrast, the patients in the group 2 and 4 had very poor prognoses regardless of TLV treatment (7% vs. 11%, p=0.823). Conclusions: U-AQP2/P-AVP is a novel predictor for the initial response to TLV in HF patients. Patients with higher U-AQP2/P-AVP may enjoy a better prognosis by long-term TLV treatment probably due to efficient resolution of congestion.

Coronary heart disease (CHD) outcomes have improved in recent decades because of better treatment, improved investigations, and better secondary prevention. The results of prognosis research have contributed to the development and evaluation of these new components of healthcare for CHD, but have also critically questioned traditional classifications of CHD, emphasized the importance of long-term outcomes in judging the success of healthcare in CHD patients, and highlighted the potential of risk stratification to guide better treatment decisions for individual patients with CHD. This chapter uses example studies to illustrate this story.
