Abstract
Aim A 12-month evaluation of the potentialities of the angiotensin II receptor inhibitor olmesartan (Olme) and the angiotensin receptor and neprilysin inhibitor (ARNI) sacubitril/valsartan in patients with arterial hypertension (AH) and dyslipidemia in the dynamics of the following indicators of chronic heart failure (CHF): N-terminal pro-brain natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF), LV global longitudinal strain (LV GLS) in diffuse myocardial fibrosis (MF) previously diagnosed by magnetic resonance imaging (MRI).Material and methods Olmesartan medoxomil (n=56) and sacubitril/valsartan (n=63) were used for 12 months in patients with hypertension, dyslipidemia and NYHA functional class II-III CHF with mid-range LVEF (CHFmrEF). MF was diagnosed by the following MRI criteria: late gadolinium enhancement and an increased proportion of extracellular matrix (33% or more). The frequency of persisting late gadolinium enhancement and the increased proportion of extracellular matrix (33% or more) was evaluated at 12 months; changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), NT-proBNP, and LV GLS were evaluated after 3, 6, and 12 months of follow-up.Results Baseline parameters did not differ between groups. The late gadolinium enhancement and increased proportion of extracellular matrix were present at baseline in all patients of both groups (100%; p=1.0). Already at 3 months, statistically significant decreases in SBP and DBP were observed in both groups. In addition, the LV GLS monitoring showed LV GLS significantly increased in both groups after 3 months and continued changing after 6 and 12 months. The NT-proBNP concentration significantly decreased in both groups already after 3 months and continued to decrease after 6 and 12 months. At 6 and 12 months, sacubitril/valsartan was superior to olmesartan in reducing SBP and NT-proBNP and in restoring LV GLS. At 12 months, the incidence of persisting, abnormal late gadolinium enhancement and increased proportion of extracellular matrix was significantly less in the ARNI group.Conclusion Olmesartan was demonstrated effective in the multi-modality therapy of CHFmrEF and MF in patients with AH and dyslipidemia. ARNI was superior to olmesartan in this regard, but further research of this issue is required.

Abstract
INTRODUCTION Hypertrophic cardiomyopathy (HCM) is one of the most common genetic causes of heart disease. Since the initial description of HCM, there have been minimal strides in management options. Obstructive HCM constitutes a larger subset of patients with increased left ventricular outflow tract gradients causing symptoms. Septal reduction therapy (SRT) has been successful, but it is not the answer for all patients and is not disease modifying. AREAS COVERED Current guideline recommendations include beta-blockers, calcium channel blockers, or disopyramides for medical management, but there lacks evidence of much benefit with these drugs. In recent years, there has been the emergence of cardiac myosin inhibitors (CMI) which have demonstrated positive results in patients with both obstructive and non-obstructive HCM. In addition to CMIs, other drugs have been investigated as we have learned more about HCM's pathological mechanisms. Drugs targeting sodium channels and myocardial energetics, as well as repurposed drugs that have demonstrated positive remodeling are being investigated as potential therapeutic targets. Gene therapy is being explored with vast potential for the treatment of HCM. EXPERT OPINION The armamentarium of therapeutic options for HCM is continuously increasing with the emergence of CMIs as mainstays of treatment. The future of HCM treatment is promising.

Abstract
BACKGROUND Studies suggest that right ventricular (RV) fibrosis is associated with RV remodeling and long-term outcomes in patients with tetralogy of Fallot (TOF). Pre-operative hypoxia may increase expression of hypoxia inducible factor-1-alpha (HIF1α) and promote transforming growth factor β1 (TGFβ1)-mediated fibrosis. We hypothesized that there would be associations between: (1) RV fibrosis and RV function, (2) HIF1α variants and RV fibrosis, and (3) HIF1α variants and RV function among post-surgical TOF cases. METHODS We retrospectively measured post-surgical fibrotic load (indexed volume and fibrotic score) from 237 TOF cases who had existing cardiovascular magnetic resonance imaging using late gadolinium enhancement (LGE), and indicators of RV remodeling (i.e., ejection fraction [RVEF] and end-diastolic volume indexed [RVEDVI]). Genetic data were available in 125 cases. Analyses were conducted using multivariable linear mixed-effects regression with a random intercept and multivariable generalized Poisson regression with a random intercept. RESULTS Indexed fibrotic volume and fibrotic score significantly decreased RVEF by 1.6% (p = 0.04) and 0.9% (p = 0.03), respectively. Indexed fibrotic volume and score were not associated with RVEDVI. After adjusting for multiple comparisons, 6 of the 48 HIF1α polymorphisms (representing two unique signals) were associated with fibrotic score. None of the HIF1α polymorphisms were associated with indexed fibrotic volume, RVEDVI, or RVEF. CONCLUSION The association of some HIF1α polymorphisms and fibrotic score suggests that HIF1α may modulate the fibrotic response in TOF.

Abstract
Fibrosis is one of the main components in the progression of most cardiovascular diseases, including coronary heart disease, by causing structural changes in the myocardium and vascular wall. The quantitative and qualitative characteristics of fibrosis of the myocardium are responsible for decreasing its elastic properties, developing diastolic dysfunction, impairing myocardial contractility, developing systolic dysfunction and cardiac arrhythmias, and worsening coronary blood flow in patients with heart failure of different etiologies. The important aspect of studying fibrosis is not only its interpretation as a model of the typical pathological process, but also its consideration as a systemic lesion of various organs and tissues. At the same time, the identification of myocardial fibrosis biomarkers that are available for their determination in circulating blood is of particular interest. Since there was evidence for the role of fibrosis in developing dysfunction of various organs and ensuring the systematicity of most diseases, especially at their development stages, the process of fibrosis came to be regarded as a promising therapeutic target. It is relevant to further investigate myocardial fibrosis, which is aimed at increasing the efficiency of its diagnosis and predicting its course and pathogenetically sound therapy.

Abstract
Aldosterone is considered to exert direct effects on the myocardium and the sympathetic nervous system. Both QT time and heart rate (HR) variability (HRV) are considered to be markers of arrhythmic risk and autonomous dysregulation. In this study, we investigated the associations between aldosterone, QT time, and HRV in patients with arterial hypertension.We recruited 477 hypertensive patients (age: 60.2 ± 10.2 years; 52.3% females) with a mean systolic/diastolic 24-hour ambulatory blood pressure monitoring (ABPM) value of 128 ± 12.8/77.1 ± 9.2 mmHg and with a median of 2 (IQR: 1-3) antihypertensive agents. Patients were recruited from the outpatient clinic at the Department of Internal Medicine of the Medical University of Graz, Austria. Blood samples, 24-hour HRV derived from 24-hour blood pressure monitoring (ABPM) and ECG's were obtained. Plasma aldosterone and plasma renin concentrations were measured by means of a radioimmunoassay. Twenty-four-hour urine specimens were collected in parallel with ABPM.Mean QTc was 423.3 ± 42.0 milliseconds for males and 434.7 ± 38.3 milliseconds for females. Mean 24H-HR and 24H-HRV was 71.9 ± 9.8 and 10.0 ± 3.6 bpm, respectively. In linear regression analyses adjusted for age, sex, body mass index, ABPM, and current medication, aldosterone to active renin ratio (AARR) was significantly associated with the QTc interval, a marker for cardiac repolarization abnormalities (mean = 426 ± 42.4 milliseconds; β-coefficient = 0.121; P = 0.03) as well as with the 24-hour heart rate variability a surrogate for autonomic dysfunction (median = 9.67 [IQR = 7.38-12.22 bpm]; β-coefficient = -0.133; P = 0.01).In hypertensive patients, AARR is significantly related to QTc prolongation as well as HRV. Further studies investigating the effects of mineralocorticoid receptor blocker and aldosterone synthase inhibitors on QTc and HRV are warranted.

Abstract
Despite declines in heart failure morbidity and mortality with current therapies, rehospitalization rates remain distressingly high, substantially affecting individuals, society, and the economy. As a result, the need for new therapeutic advances and novel medical devices is urgent. Disease-related left ventricular remodeling is a complex process involving cardiac myocyte growth and death, vascular rarefaction, fibrosis, inflammation, and electrophysiological remodeling. Because these events are highly interrelated, targeting a single molecule or process may not be sufficient. Here, we review molecular and cellular mechanisms governing pathological ventricular remodeling.

Abstract
AIMS/OBJECTIVES Patients with implantable cardioverter defibrillators (ICD) often receive an adjunctive anti-arrhythmic therapy. We propose that an addition of spironolactone will reduce the number of clinically significant ventricular arrhythmias and ICD-related therapies. METHODS AND RESULTS In a multicentre retrospective study, 64 patients with ischaemic and non-ischaemic dilated cardiomyopathy whose left ventricular ejection fraction (LVEF) was <35% and with ICD were selected. Amongst these patients, 28 patients were on spironolactone and 36 were not taking spironolactone. The ICD interrogation data were analysed for a maximum of 12 months. Wilcoxon Rank Sum test was used to compare the study and control groups. The outcomes were: (1) the number of shocks/anti-tachycardia pacing (ATP) episodes and (2) the number of episodes of ventricular tachycardia (VT) requiring ATP, non-sustained VT (NSVT), and ventricular fibrillation (VF) over the study period. The spironolactone group had fewer monthly, VTs (P=0.027) (requiring ATP). The two groups did not differ in the number of NSVT or VF per month. CONCLUSION Addition of spironolactone as an adjunct to ICD therapy in patients with congestive heart failure (CHF) reduces VT requiring ATP, but does not affect NSVT or VF per month.
