Aim. To develop a risk stratification scale for predicting cardiovascular events (CVEs) in patients with chronic coronary artery disease (CAD) based on the data from the PROGNOZ IBS registry.Material and methods. The PROGNOZ IBS registry included 641 patients (men, 500; women, 141) living in Moscow and the Moscow Region, who were routinely admitted to the National Medical Research Center for Therapy and Preventive Medicine from January 1, 2004 to December 31, 2007 with a preliminary diagnosis of CAD. All included participants underwent coronary angiography during hospitalization. The diagnosis of CAD was verified in 84% of patients. The vital status was established in 551 (86%) patients in 2010 and 583 (92%) in 2014. The follow-up period was 7 years. A multivariate statistical analysis of the predictive value of data obtained during primary hospitalization was carried out.Results. The enhanced risk stratification scale included factors with the highest predictive value for developing CVEs. The presence of NYHA class III-IV heart failure increased the relative risk of CVEs by 5,4 times (3 points), atherosclerotic aortic stenosis by 2,8 times (2 points), stroke by 2,3 times (3 points), a confirmed diagnosis of CAD by 1,7 times (1  point), the presence of dyspnea by 1,4 times (1 point), unstable CAD course in the last 3 months by 1,4 times (1 point), taking diuretics before hospitalization by 1,9 times (1 point), left ventricular ejection fraction of 40-60% and left ventricular diastolic dysfunction according to echocardiography by 1,9 and 2 times (1 point each), respectively, an increase in the heart rate according resting electrocardiography >90 bpm by 1,7 times (1 point), the presence of chronic lung disease or renal failure by 1,5 times (1 point). Seven-year risk of fatal and nonfatal CVEs in patients with CAD in case of score of 0-3 is considered low, score of 4-5 points — moderate (increase in CVE risk by 3 times), score of ≥6 — high (increase in CVE risk by 9 times).Conclusion. The enhanced risk stratification scale allows predicting the risk of fatal and non-fatal CVC in patients with suspected and confirmed CAD and may be used for widespread use due to informative value, simplicity and availability.

Abstract PurposeTrastuzumab improves survival in patients with HER2+ early breast cancer. However, cardiotoxicity remains a concern, particularly in the curative setting, and there are limited data on its incidence outside of clinical trials. We retrospectively evaluated the cardiotoxicity rates (left ventricular ejection fraction [LVEF] decline, congestive heart failure [CHF], cardiac death or trastuzumab discontinuation) and assessed the performance of a proposed model to predict cardiotoxicity in routine clinical practice.MethodsPatients receiving curative trastuzumab between 2011-2018 were identified. Demographics, treatments, assessments and toxicities were recorded. Fisher’s exact test, chi-squared and logistic regression were used.Results931 patients were included in the analysis. Median age was 54 years (range 24-83) and Charlson comorbidity index 0 (0-6), with 195 patients (20.9%) aged 65 or older. 228 (24.5%) were smokers. Anthracyclines were given in 608 (65.3%). Median number of trastuzumab doses was 18 (1-18). The HFA-ICOS cardiovascular risk was low in 401 patients (43.1%), medium in 454 (48.8%), high in 70 (7.5%) and very high in 6 (0.6%).Overall, 155 (16.6%) patients experienced cardiotoxicity: LVEF decline≥10% in 141 (15.1%), falling below 50% in 55 (5.9%), CHF NYHA class II in 42 (4.5%) and class III-IV in 5 (0.5%) and discontinuation due to cardiac reasons in 35 (3.8%). No deaths were observed.Cardiotoxicity rates increased with HFA-ICOS score (14.0% low, 16.7% medium, 30.3% high/very high; p=0.002). ConclusionsCardiotoxicity was relatively common (16.6%), but symptomatic heart failure on trastuzumab was rare in our cohort. The HFA-ICOS score identifies patients at high risk of cardiotoxicity

517 Background: M in combination with T has shown promising activity and cardiac safety in MBC patients (pts). We conducted a randomized Phase III trial of first-line M plus T and P (MTP) versus T plus P (TP) in HER2+ MBC pts. Methods: Pts with HER2+ (by FISH) MBC ≥ 18 years and ECOG 0-1, who had received no prior chemotherapy for metastatic disease, were eligible. Left ventricular ejection fraction should be within normal institutional limits. Prior (neo-) adjuvant anthracyclines, T or P were permitted, if completed >1 year before the start of the study. Pts received M 50 mg/m2 q3w for 6 cycles, T 4 mg/kg loading dose followed by 2 mg/kg qw, and P 80 mg/m2qw, or T+P at the same doses until progression or toxicity. Primary outcome was progression-free survival (PFS). Enrollment of 332 pts would provide 80% power with a 5% significance to detect an improvement in PFS with MTP, assuming a median PFS of 8 months in TP and a hazard ratio (HR) of 0.70. Results: 363 pts enrolled (MTP 181, TP 183), 360 received treatment. The two groups were well balanced for demographics, pretreatment characteristics and extent of disease. One third of the pts had prior exposure to anthracyclines, but almost none to trastuzumab (1% and 2% in MTP and TP arms, respectively). Six cycles of M could be given to 72% of the pts. With a median follow-up of 31 months, median PFS was 16.1 and 14.5 months with MTP and TP, respectively (HR 0.84, P=0.174). In pts with ER and PR-negative tumors, PFS was 20.7 and 14.0 months, respectively (HR, 0.68; 95% CI 0.47–0.99). Median overall survival (OS) was 33.6 and 28.9 months, respectively (HR, 0.79, P=0.083). In ER and PR-negative tumors, OS was 38.2 and 27.9 months, respectively (HR, 0.63; 95% CI 0.42–0.93). The incidence of NYHA Class III/IV congestive heart failure was 3% with MTP and there were 2 cardiac deaths with TP. The frequency of adverse events was higher with MTP, especially myelosuppression, stomatitis and gastrointestinal intolerance. Conclusions: The trial failed to demonstrate a significant clinical improvement with the addition of M to TP. The clinical benefit observed in an exploratory analysis in the ER and PR-negative population deserves consideration for further clinical trials. Clinical trial information: NCT00294996.

Abstract Aims Diuretics in heart failure (HF) are commended to relieve symptoms at lowest dosage effective. Dilated cardiomyopathy (DCM) is a particular HF setting with several variables that may influence disease trajectory. We aimed to assess the long-term use of diuretics in DCM, the possibility of withdrawal and to explore the prognostic correlations. Methods and results All consecutive DCM patients enrolled from 1990 to 2018 were considered eligible. All the patients had available the information about the furosemide-equivalent dose at baseline and at follow-up evaluation within 24 months. Patients were categorized in stable (diuretic dose variation <50%), increasers (diuretics dose increase ≥50% or initiation of diuretic therapy), and decreasers (diuretics dose decrease ≥50% or never prescribed diuretics in the 24-months observation period). The prognostic role of the diuretics trajectory group was assessed with Kaplan Meier analysis and with a time-dependent multivariable model. The outcome measure was a composite of all-cause death/heart transplantation/HF hospitalization (ACD/HTx/HFH). 908 patients were included [mean age 50 ± 16, 70% male sex, 24% NYHA class III or IV, mean left ventricular ejection fraction (LVEF) 31 ± 9%, 66% treated with diuretics at baseline]. The furosemide-equivalent dose at enrolment had a linear association with the risk of outcome. Compared to other groups, decreaser patients were younger, had less HF symptoms, higher LVEF and more dilated left atrium. Decreasers had a lower prescription rate of diuretics and less frequent indication to renin-angiotensin inhibitors and mineralocorticoid receptors antagonists. Over a median follow-up of 122 (62–195) months decreasers had the lowest incidence of outcome, followed by stable, while increasers had the worst outcome (P < 0.001). After adjustment for other prognosticators, compared to stable patients, decreasers had a reduced risk of ACD/HTx/HFH [HR: 0.497 (95% CI: 0.337–0.731)] while increasers had the highest risk of adverse outcome [HR: 2.027 (95% CI: 1.254–3.276)]. Similarly, amongst patients taking diuretics at baseline, the diuretics withdrawal was in independent outcome predictor. The only multivariable predictors of diuretics withdrawal were younger age and lower furosemide-equivalent dose at enrolment. Conclusions In DCM patients the diuretics dose at baseline is a strong prognosticator. Diuretics dose reduction or its withdrawal provides a prognostic benefit on hard outcome. Diuretics tapering in selected patients should be considered in the short-term follow-up to improve DCM prognosis.

Abstract Background Arterial stiffness is strongly linked to the pathogenesis of heart failure and the development of acute decompensation in patients with stable chronic heart failure. This study aimed to compare arterial stiffness indices in patients with heart failure with reduced ejection fraction (HFrEF) during the acute decompensated state, and three months later after hospital discharge during the compensated state. Results One hundred patients with acute decompensated HFrEF (NYHA class III and IV) and left ventricular ejection fraction ≤ 35% were included in the study. During the initial and follow-up visits, all patients underwent full medical history taking, clinical examination, transthoracic echocardiography, and non-invasive pulse wave analysis by the Mobil-O-Graph 24-h device for measurement of arterial stiffness. The mean age was 51.6 ± 6.1 years and 80% of the participants were males. There was a significant reduction of the central arterial stiffness indices in patients with HFrEF during the compensated state compared to the decompensated state. During the decompensated state, patients presented with NYHA FC IV (n = 64) showed higher AI (24.5 ± 10.0 vs. 16.8 ± 8.6, p < 0.001) and pulse wave velocity (9.2 ± 1.3 vs. 8.5 ± 1.2, p = 0.021) than patients with NYHA FC III, and despite the relatively smaller number of females, they showed higher stiffness indices than males. Conclusions Central arterial stiffness indices in patients with HFrEF were significantly lower in the compensated state than in the decompensated state. Patients with NYHA FC IV and female patients showed higher stiffness indices in their decompensated state of heart failure.

Background: Acute rheumatic fever (ARF) and acute rheumatic carditis (ARC) continue to be a major public health problem in developing countries. Objective: To study the characteristics of children with ARC being treated at a tertiary centre. Methods and Results: We studied 126 children (mean age 10.4 ± 2.3 years, range 5–15 years, 60% males) diagnosed with ARC by treating cardiologists. Most had lower socio-economic status. Fifty of 126 (40%) presented with a first episode of ARC. Joint symptoms were present in 29% and fever in 25%. Only 2.4% had subcutaneous nodules and none had erythema marginatum or chorea. Fifty-one percent presented in NYHA class II and 29% in NYHA class III or IV. Tachycardia and heart failure were present in 53% and 21%, respectively. Recent worsening of NYHA class (dyspnoea) was the commonest feature (48%). Laboratory investigations showed raised antistreptolysin O titres (>333 units) in only 36.7% of patients. Raised C-reactive protein (CRP) was present in 70%, while raised erythrocyte sedimentation rate was found in only 37% of patients. On the basis of above findings, the modified Jones criteria (2015) for the diagnosis of ARF were satisfied only in 46% of children. Echocardiography showed mitral valve thickening in 77% and small nodules on the tip of the leaflets in 43% (27 and 8%, respectively for aortic valve). Left ventricular ejection fraction was <50% in only 3 patients. The dominant valve lesion was mitral regurgitation (MR) (present in 95% of patients; severe in 78%, moderate in 15%), while aortic regurgitation was present in 44% (severe in 14%). Conclusions: The criteria are often not satisfied by patients being treated for ARC. Recent unexplained worsening of dyspnoea, young age, significant MR, echocardiographic nodules, and elevated CRP are important indicators.

Abstract Aims Hypertrophic cardiomyopathy (HCM) is an inheritable disease that leads to sudden cardiac death and heart failure (HF). Sarcomere mutations (SMs) have been associated with HF. However, the differences in ventricular function between SM-positive and SM-negative HCM patients are poorly characterized. Methods and results  Of the prospectively enrolled 374 unrelated HCM patients in Taiwan, 115 patients underwent both 91 cardiomyopathy-related gene screening and cardiovascular magnetic resonance (45.6 ± 10.6 years old, 76.5% were male). Forty pathogenic/likely pathogenic mutations were identified in 52 patients by next-generation sequencing. The SM-positive group were younger at first cardiovascular event (P = 0.04) and progression to diastolic HF (P = 0.02) with higher N-terminal pro-brain natriuretic peptide (NT-proBNP) [New York Heart Association (NYHA) Class III/IV symptoms with left ventricular ejection fraction &gt; 55%] than the SM-negative group (P &lt; 0.001). SM-positive patients had a greater extent of late gadolinium enhancement (P = 0.01), larger left atrial diameter (P = 0.03), higher normalized peak filling rate (PFR) and PFR ratio, and a greater reduction in global longitudinal strain than SM-negative patients (all P ≤ 0.01). During mean lifelong follow-up time (49.2 ± 15.6 years), SM-positive was a predictor of earlier HF (NYHA Class III/IV symptoms) after multivariate adjustment (hazard ratio 3.5; 95% confidence interval 1.3–9.7; P = 0.015). Conclusion SM-positive HCM patients had a higher extent of myocardial fibrosis and more severe ventricular diastolic dysfunction than those without, which may contribute to earlier onset of advanced HF, suggesting the importance of close surveillance and early treatment throughout life.

BACKGROUND Direct comparisons of combined (C-ABL) and non-combined (NC-ABL) endo-epicardial ventricular tachycardia (VT) ablation outcomes are scarce. We aimed to investigate the long-term clinical efficacy and safety of these 2 strategies in ischemic heart disease (IHD) and nonischemic cardiomyopathy (NICM) patients. METHODS Multicentric observational registry including 316 consecutive patients who underwent catheter ablation for drug-resistant VT between January 2008 and July 2019. Primary and secondary efficacy endpoints were defined as VT-free survival and all-cause death after ablation. Safety outcomes were defined by 30-days mortality and procedure-related complications. RESULTS Most of the patients were male (85%), with IHD (67%) and mean age of 63±13 years. During a mean follow-up of 3±2 years, 117 (37%) patients had VT recurrence and 73 (23%) died. Multivariate survival analysis identified electrical storm (ES) at presentation, IHD, left ventricular ejection fraction (LVEF), New York Heart Association (NYHA) class III/IV, and C-ABL as independent predictors of VT recurrence. In 135 patients undergoing repeated procedures, only C-ABL and ES were independent predictors of relapse. The independent predictors of mortality were C-ABL, ES, LVEF, age and NYHA class III/IV. C-ABL survival benefit was only seen in patients with a previous ablation (P for interaction=0.04). Mortality at 30-days was similar between NC-ABL and C-ABL (4% vs. 2%, respectively, P=0.777), as was complication rate (10.3% vs. 15.1% respectively, P=0.336). CONCLUSION A combined endo-epicardial approach was associated with greater VT-free survival and lower all-cause death in IHD and NICM patients undergoing repeated VT catheter ablations. Both strategies seem equally safe.

<b><i>Background:</i></b> Somatostatin inhibits intestinal motility and hormonal secretion and is a potent arterial vasoconstrictor of the splanchnic blood flow. It is unknown if somatostatin concentrations are associated with central hemodynamic measurements in patients with advanced heart failure (HF). <b><i>Methods:</i></b> A prospective study of HF patients with a left ventricular ejection fraction (LVEF) &#x3c;45% referred to right heart catheterization (RHC) for evaluation for heart transplantation (HTX) or left ventricular assist device (LVAD). <b><i>Results:</i></b> Fifty-three patients were included with mean LVEF 18 ± 8% and majority in NYHA-class III–IV (79%). Median plasma somatostatin concentration was 18 pmol/L. In univariable regression analysis, log(somatostatin) was associated with increased central venous pressure (CVP; <i>r</i><sup>2</sup> = 0.14, <i>p</i> = 0.003) and a reduced cardiac index (CI; <i>r</i><sup>2</sup> = 0.15, <i>p</i> = 0.004). When adjusted for selected clinical variables (age, gender, LVEF, eGFR and BMI), log(somatostatin) remained a significant predictor of CVP (<i>p</i> = 0.044). Increased somatostatin concentrations predicted mortality in multivariable models (hazard ratio: 5.2 [1.2–22.2], <i>p</i> = 0.026) but not the combined endpoint of death, LVAD implantation or HTX. <b><i>Conclusions:</i></b> Somatostatin concentrations were associated with CVP and CI in patients with HF. The pathophysiological mechanism may be related to congestion and/or hypoperfusion of the intestine. Somatostatin was an independent predictor of mortality in advanced HF.

Introduction: Chagas’ disease causes different clinical expressions in the heart and permanent pacing due to bradycardia is not uncommon. Objective: Predictors of death in patients with Chagas Cardiomyopathy requiring pacemaker (PM) are unknown. This is the aim of this study. Methods: We prospectively evaluated 529 patients included in the Pacinchagas Study - Risk Stratification in Pacemaker Patients with Chagas Cardiomyopathy, which primary objective is to create a risk score to predict death in this population. The patients are submitted to an extent questionnaire which included clinical (NYHA class, symptoms, comorbidities and medications) functional (electrocardiography, Holter and echocardiography) and electronic variables (burden of pacing and arrhythmias). Patients with at least 6 months of follow-up were included in this preliminar analysis. Results: The cohort included 337 (63.7%) females, the mean age was 62.3±11.9 years and 63.1% were in NYHA class I. Indication for PM implantation was atrioventricular block, sick sinus syndrome, atrial fibrillation with slow ventricular response and unknown in 72.0%; 20.4%; 5.1% and 2.5%, respectively. During a mean follow-up of 1.5±0.6 years, 62 (11.7%) patients died. The mean time of PM implantation was not different between the dead and the survivors (11.9±9.0years versus 11.1±8.6years, P=0.503). Twenty-five deaths (40.3%) were sudden, 22 (35.5%) were due to heart failure, 6 (9.7%) were due to other cardiovascular causes, and 7 (11.3%) were due to noncardiovascular causes. The cause of death could not be determined in two patients (3.2%). Cox proportional hazards identified three predictors of death: NYHA class III/IV (Hazard Ratio [HR] 5.661; 95% Confidence Interval [95%IC] 2.617-12.245; P<0.001); left ventricular ejection fraction (LVEF) ≤42% (HR 2.779; 95%IC 1.299-5.945; P=0.008) and chronic kidney disease (HR 2.635; 95%IC 1.167-5.948; P=0.020). Conclusions: This analysis of Pacinchagas study identified in a mean follow-up of one year and half, three predictors of death in PM users with Chagas Cardiomyopathy: NYHA class III/IV, LVEF≤42% and chronic kidney disease.

Resynchronisation Therapy

Cardiac resynchronisation therapy (CRT) is an efficacious and cost-effective therapy in patients with highly symptomatic systolic heart failure and delayed ventricular conduction. Current guidelines recommend CRT as a class I indication for patients with sinus rhythm, New York Heart Association (NYHA) functional class III or ambulatory class IV, a QRS duration ≥120ms, and left ventricular ejection fraction (LVEF) ≤35%, despite optimal pharmacological therapy. Recent trials resulted in an extension of current recommendations to patients with mild heart failure, patients with atrial fibrillation, and patients with an indication for permanent right ventricular pacing with the aim of morbidity reduction. The effectiveness of CRT in patients with narrow QRS, patients with end-stage heart failure and cardiogenic shock, and patients with an LVEF >35% still needs to be proved. This article reviews current evidence and clinical applications of CRT in heart failure and provides an outlook on future developments.
