Objective:Linear aerobic training periodisation (LP) is recommended in patients with coronary heart disease (CHD). However, the effects of training periodisation on right heart mechanics in CHD patients have never been examined. This study aimed to explore the effects of LP and non-linear periodisation (NLP) on right heart mechanics. Methods: We prospectively randomised CHD patients to 12 weeks aerobic training with LP or NLP. Whereas there was a weekly increase in energy expenditure with LP, there was a steeper increase during the first 3 weeks followed by a decrease the fourth week with NLP. Echocardiography at baseline and after the training period was performed to assess right ventricular free wall (RVFW) and right atrial strain. Results: Thirty CHD patients were included (NLP, n=16; LP, n=14). Traditional right and left heart parameters showed no significant time effect. There was a decrease of RVFW strain with time in both groups (+1.3±0.9% with NLP, and +1.5±0.8% with LP; p=0.033). Mid-ventricular RVFW strain changed significantly with time (+2.0±1.3% with NLP, and from +2.3±1.2% with LP; p=0.025). There was no time effect on right atrial strain. Conclusions: In stable CHD patients, LP and NLP resulted in right ventricular strain decrements with a segment-specific pattern. This study was registered on ClinicalTrials.gov (identifier number: NCT03414996). Novelty: • In stable coronary heart disease patients, both linear and non-linear aerobic training periodisation programs result in right ventricular strain decrements with time, particularly in the mid-ventricular segment • Traditional right and left heart parameters, and right atrial strain showed no significant time effect in both 12 weeks aerobic training periodisation programs

We have reported that increased left heart pressure inhibits increases in plasma renin activity (PRA), arginine vasopressin (AVP), and cortisol during arterial hypotension. The goal of this study was to determine whether increases in right heart pressure also inhibited hormonal responses to hypotension. Seven dogs were chronically instrumented with inflatable cuffs around the ascending aorta (AA), the pulmonary artery (PA), and the thoracic inferior vena cava (IVC), as well as with catheters in both atria, the abdominal aorta, and vena cava. The IVC, the PA, and the AA cuffs were inflated on different days to cause step reductions in mean arterial pressure (MAP) of 5, 10, 20, and 30% below control MAP. Graded constriction of the AA caused large increases in left atrial pressure and plasma atrial natriuretic peptide (ANP), but had no effect on plasma AVP or cortisol and caused only a small increase in PRA at the maximal reduction of MAP. Constriction of the IVC reduced both atrial pressures and plasma ANP, but stimulated increases in PRA, AVP, and cortisol. Constriction of the PA increased right atrial pressure and plasma ANP and caused increases in plasma AVP and cortisol that were similar to responses during IVC constriction, but the PRA response was only half (P < 0.05). These results indicate that increasing pressure on the right side of the heart can attenuate the PRA response to hypotension, and suggest that the inhibition is mediated by the rise in plasma ANP.

Introduction: The heart-kidney interaction in heart failure (HF) is a matter of special interest, especially due to its strong prognostic significance. The search for a reliable, non-invasive parameter with high pathophysiological and prognostic impact to evaluate HF-related renal congestion remains attractive. Doppler evaluation of intra-renal venous flow (IRVF) has been recently employed in HF patients, with a spectrum of findings ranging from a normal continuous flow to a monophasic discontinuous one, indicative of low and high degrees of renal congestion, respectively. Hypothesis: We postulated a role for right atrial dynamics in the renal congestion pathophysiology. The impairment in atrial deformation and pump function may play a primary role increasing the pulsatile backward load in the venous system, especially in acute heart failure (AHF) patients. Methods: 119 consecutive AHF patients were prospectively investigated within 48 hours from admission. Doppler-derived descriptors of renal hemodynamics included the renal arterial resistive index, IRVF pattern, venous impedance index and renal venous stasis index (RVSI). Results: Right atrial peak longitudinal strain (RAPLS) showed a strong correlation with IRVF pattern (Fig A) and various indices of RV function (TAPSE, S’, FAC) and RV coupling as represented by the TAPSE/PASP ratio (Fig B). At multivariate regression analysis, TAPSE/PASP ratio emerged as the main determinant of RVSI. On the other hand, considering only patients with a clearly impaired RV coupling (TAPSE/PASP <0.30), RAPLS emerged as the best determinant of RVSI (Fig C-D). Conclusions: Our data confirms the main role of the right heart in determining renal stasis in HF patients. When RV to pulmonary circulation uncoupling is severe, the right atrium becomes the key balancing factor in the venous renal flow response. Studies on the mechanistic contribution of the RA dysfunction and the recovery potential of interventions are warranted.

Background: Identifying candidates for left ventricular assist device surgery at risk of right ventricular failure remains difficult. The aim was to identify the most accurate predictors of right ventricular failure among clinical, biological, and imaging markers, assessed by agreement of different supervised machine learning algorithms. Methods: Seventy-four patients, referred to HeartWare left ventricular assist device since 2010 in two Italian centers, were recruited. Biomarkers, right ventricular standard, and strain echocardiography, as well as cath-lab measures, were compared among patients who did not develop right ventricular failure (N = 56), those with acute–right ventricular failure (N = 8, 11%) or chronic–right ventricular failure (N = 10, 14%). Logistic regression, penalized logistic regression, linear support vector machines, and naïve Bayes algorithms with leave-one-out validation were used to evaluate the efficiency of any combination of three collected variables in an “all-subsets” approach. Results: Michigan risk score combined with central venous pressure assessed invasively and apical longitudinal systolic strain of the right ventricular–free wall were the most significant predictors of acute–right ventricular failure (maximum receiver operating characteristic–area under the curve = 0.95, 95% confidence interval = 0.91–1.00, by the naïve Bayes), while the right ventricular–free wall systolic strain of the middle segment, right atrial strain (QRS-synced), and tricuspid annular plane systolic excursion were the most significant predictors of Chronic-RVF (receiver operating characteristic–area under the curve = 0.97, 95% confidence interval = 0.91–1.00, according to naïve Bayes). Conclusion: Apical right ventricular strain as well as right atrial strain provides complementary information, both critical to predict acute–right ventricular failure and chronic–right ventricular failure, respectively.
