Right Ventricular Dysfunction During Endurance Exercise as Determined by Pressure-Volume Analysis.

ABSTRACT: A 37-year-old athlete completed invasive endurance (90 km) bicycle exercise testing for right ventricular pressure-volume analysis. Increased right ventricular afterload caused declines in ventricular-arterial coupling and cardiac output, causing increased arteriovenous oxygen difference to maintain oxygen uptake. These findings demonstrate effects of changes in right ventricular performance on exercise capacity. (Level of Difficulty: Intermediate.).

Right ventricular dysfunction and failure in chronic pressure overload.

Project description:Right ventricular (RV) dysfunction is the main cause of death in pulmonary arterial hypertension (PAH). Our understanding of the pathophysiology of RV dysfunction is limited but improving. Methods to better diagnose RV dysfunction earlier and treatments specifically designed to minimize or reverse the remodeling process are likely to improve outcomes. We review the current understanding of RV dysfunction in chronic pressure overload and introduce some novel insights based on recent investigations into pathophysiology, diagnosis, and treatment.

Right ventricular pressure-volume loop shape and systolic pressure change in pulmonary hypertension.

Project description:Right ventricular (RV) function determines outcome in pulmonary arterial hypertension (PAH). RV pressure-volume loops, the gold standard for measuring RV function, are difficult to analyze. Our aim was to investigate whether simple assessments of RV pressure-volume loop morphology and RV systolic pressure differential reflect PAH severity and RV function. We analyzed multibeat RV pressure-volume loops (obtained by conductance catheterization with preload reduction) in 77 patients with PAH and 15 patients without pulmonary hypertension in two centers. Patients were categorized according to their pressure-volume loop shape (triangular, quadratic, trapezoid, or notched). RV systolic pressure differential was defined as end-systolic minus beginning-systolic pressure (ESP - BSP), augmentation index as ESP - BSP/pulse pressure, pulmonary arterial capacitance (PAC) as stroke volume/pulse pressure, and RV-arterial coupling as end-systolic/arterial elastance (Ees/Ea). Trapezoid and notched pressure-volume loops were associated with the highest afterload (Ea), augmentation index, pulmonary vascular resistance (PVR), mean pulmonary arterial pressure, stroke work, B-type natriuretic peptide, and the lowest Ees/Ea and PAC. Multivariate linear regression identified Ea, PVR, and stroke work as the main determinants of ESP - BSP. ESP - BSP also significantly correlated with multibeat Ees/Ea (Spearman's ρ: -0.518, P < 0.001). A separate retrospective analysis of 113 patients with PAH showed that ESP - BSP obtained by routine right heart catheterization significantly correlated with a noninvasive surrogate of RV-arterial coupling (tricuspid annular plane systolic excursion/pulmonary arterial systolic pressure ratio; ρ: -0.376, P < 0.001). In conclusion, pressure-volume loop shape and RV systolic pressure differential predominately depend on afterload and PAH severity and reflect RV-arterial coupling in PAH.

Time dependence of volume overload on right ventricular remodeling during preadolescence

Project description:We reported the RNAseq analyses of right ventricualr free wall myocardium in young volume overload (VO) C57/BL6 mice.VO was induced by the fistula between abdominal aorta and inferior vena cava (AVF) on postnatal day 7(P7). RNAseq analyses of RV free wall at P14 and P21from VO and sham-operated mice revealed that there were 981 differentially expressed genes between VO and sham group at P14, this number increased to 1907 at P21, there were 3012 differentially expressed genes between P21 and P14 sham group, and the number increased to 3470 at the presence of VO. GO analysis showed that in the VO and sham comparison, the upregulated genes mainly mediated mitosis and cell division and the downregulated genes mainly mediated heart contraction at P14, and the upregulated genes mainly mediated immune response, and downregulated genes mainly mediated cellular respiration at P21. As expected, in the normal RV development during preadolescence (from P14 to P21), upregulated genes mainly mediated oxidative phosphorylation and cellular respiration and the downregulated genes mainly mediated vasculogenesis. VO changed the RV development, the upregulated genes mainly mediated heart contraction and the down regulated genes mainly mediated vasculogenesis and cell cycle. KEGG pathway analysis revealed that cell cycle pathway was upregulated and cardiac muscle contraction and thyroid hormone signaling pathway were downregulated between VO and sham group at P14, phagosome pathway was upregulated and citrate cycle (TCA) cycle and thermogenesis were downregulated at P21 between VO and sham group. In the normal RV development, TCA cycle and cardiac muscle contraction pathway were upregulated while VO changed that to the upregulations of cardiomyopathy pathways and thyroid hormone signaling pathway. All the above changes were further confirmed by the functional tests.

Sildenafil ameliorates right ventricular early molecular derangement during left ventricular pressure overload.

Project description:Right ventricular (RV) dysfunction following left ventricular (LV) failure is associated with poor prognosis. RV remodeling is thought initiated by the increase in the afterload of RV due to secondary pulmonary hypertension (PH) to impaired LV function; however, RV molecular changes might occur in earlier stages of the disease. cGMP (cyclic guanosine monophosphate)-phosphodiesterase 5 (PDE5) inhibitors, widely used to treat PH through their pulmonary vasorelaxation properties, have shown direct cardiac benefits, but their impacts on the RV in LV diseases are not fully determined. Here we show that RV molecular alterations occur early in the absence of RV hemodynamic changes during LV pressure-overload and are ameliorated by PDE5 inhibition. Two-day moderate LV pressure-overload (transverse aortic constriction) neither altered RV pressure/ function nor RV weight in mice, while it induced only mild LV hypertrophy. Importantly, pathological molecular features were already induced in the RV free wall myocardium, including up-regulation of gene markers for hypertrophy and inflammation, and activation of extracellular signal-regulated kinase (ERK) and calcineurin. Concomitant PDE5 inhibition (sildenafil) prevented induction of such pathological genes and activation of ERK and calcineurin in the RV as well as in the LV. Importantly, dexamethasone also prevented these RV molecular changes, similarly to sildenafil treatment. These results suggest the contributory role of inflammation to the early pathological interventricular interaction between RV and LV. The current study provides the first evidence for the novel early molecular cross-talk between RV and LV, preceding RV hemodynamic changes in LV disease, and supports the therapeutic strategy of enhancing cGMP signaling pathway to treat heart diseases.

Arrhythmogenic Right Ventricular Cardiomyopathy in an Endurance Athlete Presenting with Ventricular Tachycardia and Normal Right Ventricular Function.

Project description:Arrhythmogenic right ventricular cardiomyopathy, a genetically inherited disease that results in fibrofatty replacement of normal cardiac myocytes, has been associated with sudden cardiac death in athletes. Long-term participation in endurance exercise hastens the development of both the arrhythmic and structural arrhythmogenic right ventricular cardiomyopathy phenotypes. We describe the unusual case of a 34-year-old, symptomatic, female endurance athlete who had arrhythmogenic right ventricular cardiomyopathy in the presence of a structurally normal right ventricle. Clinicians should be aware of this infrequent presentation when evaluating athletic patients who have ventricular arrhythmias and normal findings on cardiac imaging studies.

A new assessment method for right ventricular diastolic function using right heart catheterization by pressure-volume loop.

Project description:Diastolic stiffness coefficient (β) and end-diastolic elastance (Eed) are ventricular-specific diastolic parameters. However, the diastolic function of right ventricle had not been investigated sufficiently due to the lack of established evaluation method. We evaluated the validity of these parameters calculated using only data of right heart catheterization (RHC) and assessed it in patients with restrictive cardiomyopathy (RCM) and cardiac amyloidosis. We retrospectively analyzed 46 patients with heart failure who underwent RHC within 10 days of cardiac magnetic resonance (CMR). Right ventricular end-diastolic volume and end-systolic volume were calculated using only RHC data, which were found to be finely correlated with those obtained from CMR. β and Eed calculated by this method were also significantly correlated with those derived from conventional method using CMR. By this method, β and Eed were significantly higher in RCM with amyloidosis group than dilated cardiomyopathy group. In addition, the β and Eed calculated by our method were finely correlated with E/A ratio on echocardiography. We established an easy method to estimate β and Eed of right ventricle from only RHC. The method finely demonstrated right ventricular diastolic dysfunction in patients with RCM and amyloidosis.

Hemodynamic and metabolic characteristics associated with development of a right ventricular outflow tract pressure gradient during upright exercise.

Project description:BackgroundWe recently reported a novel observation that many patients with equal resting supine right ventricular(RV) and pulmonary artery(PA) systolic pressures develop an RV outflow tract(RVOT) pressure gradient during upright exercise. The current work details the characteristics of patients who develop such an RVOT gradient.MethodsWe studied 294 patients (59.7±15.5 years-old, 49% male) referred for clinical invasive cardiopulmonary exercise testing, who did not have a resting RVOT pressure gradient defined by the simultaneously measured peak-to-peak difference between RV and PA systolic pressures.ResultsThe magnitude of RVOT gradient did not correspond to clinical or hemodynamic findings suggestive of right heart failure; rather, higher gradients were associated with favorable exercise findings. The presence of a high peak RVOT gradient (90th percentile, ?33mmHg) was associated with male sex (70 vs. 46%, p = 0.01), younger age (43.6±17.7 vs. 61.8±13.9 years, p<0.001), lower peak right atrial pressure (5 [3-7] vs. 8 [4-12]mmHg, p<0.001), higher peak heart rate (159±19 vs. 124±26 beats per minute, p<0.001), and higher peak cardiac index (8.3±2.3 vs. 5.7±1.9 L/min/m2, p<0.001). These associations persisted when treating peak RVOT as a continuous variable and after age and sex adjustment. At peak exercise, patients with a high exercise RVOT gradient had both higher RV systolic pressure (78±11 vs. 66±17 mmHg, p<0.001) and lower PA systolic pressure (34±8 vs. 50±19 mmHg, p<0.001).ConclusionsDevelopment of a systolic RV-PA pressure gradient during upright exercise is not associated with an adverse hemodynamic exercise response and may represent a normal physiologic finding in aerobically fit young people.

CLINICAL SYMPTOMS OF RIGHT VENTRICULAR FAILURE IN EXPERIMENTAL CHRONIC PRESSURE LOAD ARE ASSOCIATED WITH PROGRESSIVE DIASTOLIC DYSFUNCTION

Project description:Right ventricular failure (RVF) due to pressure load is a major cause of death in congenital heart diseases and pulmonary hypertension. The mechanisms of RVF are yet unknown. Research is hampered by the lack of a good RVF model. Our aim was to study the pathophysiology of RVF in a rat model of chronic pressure load. Wistar rats (n=19) were subjected to pulmonary artery banding (PAB, 1.1mm) or sham surgery (CON). All PAB rats developed RVF (reduced cardiac output, RV stroke volume, TAPSE, increased end diastolic pressure, all p<0.05 vs. CON) but clinical symptoms of RVF (inactivity, ruffled fur, dyspnea, ascites) necessitating termination ensued in a subset (5/12) of rats (RVF+) after a period of 52Â±5 days. Rats with RVF+ had significantly worse RV function and pericardial effusion and liver congestion compared to RVF rats without symptoms (all p<0.05), despite similar pressure load (p=NS RVF vs. RVF+). Chronic pulmonary artery banding invariably leads to RV failure in rats, and a subset transitions to advanced clinical RVF. RVF is characterized by enhanced contractility, progressive diastolic dysfunction and derangement of energy metabolism, thus improving diastolic function and targeting RV metabolism may be the keys to treating RVF.

Transcriptomic and Functional Analyses of Mitochondrial Dysfunction in Pressure Overload-induced Right Ventricular Failure

Project description:Background: In complex congenital heart disease patients such as those with tetralogy of Fallot, the right ventricle (RV) is subject to pressure overload, leading to RV hypertrophy and eventually RV failure. The mechanisms that promote the transition from stable RV hypertrophy to RV failure are unknown. We evaluated the role of mitochondrial bioenergetics in the development of RV failure. Methods: We created a murine model of RV pressure overload by pulmonary artery banding and compared with sham-operated controls. Gene expression by RNA-sequencing, oxidative stress, mitochondrial respiration, dynamics, and structure were assessed in pressure overload-induced RV failure. Results: RV failure was characterized by decreased expression of electron transport chain genes and mitochondrial antioxidant genes (aldehyde dehydrogenase 2 and superoxide dismutase 2) and increased expression of oxidant stress markers (heme oxygenase, 4-hydroxynonenal). The activities of all electron transport chain complexes decreased with RV hypertrophy and further with RV failure (oxidative phosphorylation: sham 552.3±43.07 vs. RV hypertrophy 334.3±30.65 vs. RV failure 165.4±36.72 pmol/(sec*ml), p<0.0001). Mitochondrial fission protein DRP1 did not change, while MFF decreased and fusion protein OPA1 decreased. In contrast, transcription of electron transport chain genes increased in the left ventricle of RV failure. Conclusion: Pressure overload-induced RV failure is characterized by decreased transcription and activity of electron transport chain complexes and increased oxidative stress which are associated with decreased energy generation. An improved understanding of the complex processes of energy generation could aid in developing novel therapies to mitigate mitochondrial dysfunction and delay the onset of RV failure.
