Abstract
Background Chronic kidney disease (CKD) is associated with an increased risk of pulmonary hypertension, which may lead to right ventricular (RV) pressure overload and RV dysfunction. However, the presence of subclinical changes in RV structure or function in early CKD and the influence of these changes on mortality are not well studied. We hypothesized that early CKD, as indicated by elevated albuminuria or mild reductions in estimated glomerular filtration rate (eGFR), is associated with greater RV dilation and RV mass. Methods We included 4063 participants (age 45-84 years) without baseline clinical cardiovascular disease from the Multi-Ethnic Study of Atherosclerosis. The associations of baseline creatinine-cystatin C-based eGFR and albuminuria with cardiac magnetic resonance-derived RV measures (2000-02) were examined cross-sectionally with linear regression models. Cox regression models were used to examine whether RV parameters modified the associations of eGFR and albuminuria with all-cause mortality. Results Participants with reductions in eGFR primarily within the 60-89 mL/min/1.73 m2 category had smaller RV end-diastolic and end-systolic volumes and stroke volume (all adjusted P-trends <.001) than those with eGFR ≥90 mL/min/1.73 m2, an association that was predominantly seen in participants with albuminuria below 30 mg/g creatinine. Albuminuria was more strongly associated with death among those with lower RV volumes (P-values for interaction <.03). Conclusions Among community-dwelling adults, reductions in eGFR primarily within the normal range were associated with smaller RV volumes and the association of albuminuria with worse survival was stronger among those with smaller RV volumes. Further studies are needed to elucidate the underlying mechanistic pathways that link kidney measures and RV morphology.

[PMID: 36362485 PMCID: PMC9655282 DOI: 10.3390/jcm11216257] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 10/18/2022] [Accepted: 10/21/2022] [Indexed: 08/30/2023] Open
Abstract
Right ventricular remodeling has been neglected in patients with arterial hypertension as all studies have concentrated on the left ventricle and left atrial-ventricular and ventricular-arterial coupling. The development of novel imaging techniques has revealed significant impairment in the RV structure, systolic and diastolic function, and, afterwards, RV longitudinal mechanics. However, these changes are subclinical and can be detected only after comprehensive imaging analysis. The latest findings confirm the importance of RV hypertrophy, systolic, and diastolic dysfunction in the prediction of cardiovascular adverse events in the hypertensive population, representing an important clinical implication of these parameters. In clinical practice, 2D echocardiography is widely used for the evaluation of RV remodeling. However, existing techniques are largely underused and limited to a few basic parameters (RV thickness and TAPSE), which are not nearly enough for a detailed assessment of RV remodeling. In addition, 3D echocardiography provides the possibility of accurate evaluation of RV volumes and ejection fraction, which are comparable with results obtained by cardiac magnetic resonance (CMR)-a gold standard for the evaluation of the RV. The use of 3D echocardiography is limited due to its low availability, the lack of adequate software necessary for the calculation of results, and the necessity for a higher level of expertise. CMR provides all information required for a detailed assessment of RV structural, functional, and mechanical remodeling, and it is considered the reference method for this type of evaluation. Furthermore, it is the only technique that may provide tissue characterization and evaluation of the interstitial space, which is essential for hypertensive heart disease. The aim of this review is to provide the current level of evidence regarding RV remodeling in patients with arterial hypertension evaluated with different imaging techniques and various parameters from each method.

Association between cumulative blood pressure in early adulthood and right ventricular structure and function in middle age: The CARDIA study. Clin Cardiol 2022; 45:83-90.

Abstract
OBJECTIVE Cumulative blood pressure (BP) exposure is a known risk factor for cardiovascular disease. This study sought to investigate the association between cumulative BP from early adulthood to middle age and right ventricular (RV) structure and function in middle age. METHODS We included 2844 participants from the CARDIA study (Coronary Artery Risk Development in Young Adults). Cumulative BP over the 30-years follow-up was defined as the sum of the product of mean BP for each pair of consecutive examinations and the time interval between these two consecutive examinations in years. RV structure and function were assessed by echocardiography. The main analyses utilized logistic and linear regression models. RESULTS In fully adjusted models, higher cumulative systolic BP was independently associated with lower tricuspid annular plane systolic excursion (TAPSE), right ventricular peak systolic velocity (RVS'), right ventricular early diastolic velocity (RVe'), and higher pulmonary arterial systolic pressure. Higher cumulative diastolic BP was independently associated with smaller RV basal diameter, lower TAPSE, RVS', and RVe'. For categorical analyses of RV dysfunction, cumulative systolic BP was not related to systolic dysfunction. Per 1-SD increase in cumulative systolic BP was associated with a higher risk of diastolic dysfunction, while an increase in cumulative diastolic BP was associated with a higher risk of systolic dysfunction and diastolic dysfunction. CONCLUSIONS Cumulative exposure to increased BP from early adulthood to middle age was associated with incipient RV systolic and diastolic dysfunction in middle age. Exposure to higher diastolic BP levels from early adulthood to middle age was associated with a smaller RV basal diameter in middle age.

Abstract
OBJECTIVE We sought to investigate the predictive value of right ventricular (RV) remodeling and 24-h blood pressure (BP) patterns on long-term cardiovascular prognosis in the initially untreated hypertensive patients. METHODS The current study included 505 initially untreated hypertensive patients who were consequently included in this study from 2007 to 2012. All the patients underwent laboratory analysis, 24-h BP monitoring and echocardiographic examination at baseline. The patients were followed for a median period of 9 years. The adverse outcome was defined as the hospitalization due to cardiovascular events (atrial fibrillation, myocardial infarction, myocardial revascularization, heart failure, stroke, or cardiovascular death). RESULTS During the 9-year follow-up period adverse cardiovascular events occurred in 82 hypertensive patients. Night-time SBP, the nondipping BP pattern, left ventricle hypertrophy, RV hypertrophy, right atrial enlargement, RV diastolic dysfunction, and RV systolic dysfunction were associated with adverse cardiovascular events. Nevertheless, night-time SBP, the nondipping BP pattern, mitral E/e', left ventricle hypertrophy, and RV hypertrophy were the only independent predictors of cardiovascular events. When all four BP patterns were included in the model, only the reverse dipping BP pattern was an independent predictor of cardiovascular events. CONCLUSION The present investigation showed that RV hypertrophy and the reverse dipping BP pattern were independent long-term predictors of the cardiovascular outcome. Detailed echocardiographic evaluation and 24-h ambulatory blood pressure monitoring should be performed even in low-risk hypertensive patients.

Abstract
BACKGROUND Mild-to-moderate hypertension with preserved left ventricular (LV) function may be associated with right ventricular (RV) dysfunction and increased pulmonary vascular resistance (PVR). METHODS The present study explored the adequacy of RV-pulmonary arterial (PA) coupling in 211 never-treated hypertensive patients (mean blood pressure, BP 112 ± 12 mmHg) and 246 controls (BP 93 ± 12 mmHg). They underwent a comprehensive transthoracic Doppler echocardiography, and RV-PA coupling was estimated by the tricuspid annular plane systolic excursion (TAPSE) to systolic pulmonary artery pressure (PASP) ratio (TAPSE/PASP). RESULTS Compared with the controls, hypertensive patients had increased LV wall thickness and decreased trans-mitral E/A with only slight but significant increase in transmitral Doppler E wave to tissue Doppler mitral annulus e' wave ratio (6.3 ± 1.9 vs. 5.8 ± 1. 5, P < 0.05). RV dimensions and indices of either systolic or diastolic function were not different. PASP was increased in the hypertensive patients (25 ± 7 vs. 21 ± 7 mmHg, P < 0.001), as was PVR estimated from the tricuspid regurgitation velocity to right ventricular outflow tract velocity ratio (1.7 ± 0.4 vs. 1.5 ± 0.5 Wood units, P < 0.001). The TAPSE/PASP ratio was decreased (1.08 ± 0.35 vs. 1.43 ± 0.67 mm/mmHg, P < 0.001). This difference was mainly driven by male hypertensive patients. At multivariable analysis, the only independent predictors of decreased TAPSE/PASP were age and blood pressure. CONCLUSION The TAPSE/PASP is markedly decreased in hypertension without heart failure, chiefly in men, with only slight increases in estimates of LV filling pressure or PVR, suggesting RV-PA uncoupling.

Abstract
Arterial stiffness (AS) and obesity are recognized as important risk factors of cardiovascular disease (CVD). The purpose of this study was to investigate the relationship between AS and obesity. AS was defined as high augmentation index (AIx) and low elasticity (C1, large artery elasticity; C2, small artery elasticity) in participants enrolled in the Multi-Ethnic Study of Atherosclerosis at baseline. We compared AIx, C1, and C2 by body mass index (BMI) (< 25, 25-29.9, 30-39.9, ⩾ 40 kg/m2) and waist-hip ratio (WHR) (< 0.85, 0.85-0.99, ⩾ 1). The obesity-AS association was tested across 10-year age intervals. Among 6177 participants (62 ± 10 years old, 52% female), a significant inverse relationship was observed between obesity and AS. After adjustments for CVD risk factors, participants with a BMI > 40 kg/m2 had 5.4% lower AIx (mean difference [Δ] = -0.82%; 95% CI: -1.10, -0.53), 15.4% higher C1 (Δ = 1.66 mL/mmHg ×10; 95% CI: 1.00, 2.33), and 40.2% higher C2 (Δ = 1.49 mL/mmHg ×100; 95% CI: 1.15, 1.83) compared to those with a BMI < 25 kg/m2 (all p for trend < 0.001). Participants with a WHR ⩾ 1 had 5.6% higher C1 (∆ = 0.92 mL/mmHg ×10; 95% CI: 0.47, 1.37) compared to those with a WHR < 0.85. The WHR had a significant interaction with age on AIx and C2, but not with BMI; the inverse relationships of the WHR with AIx and C2 were observed only in participants < 55 years between the normal (WHR < 0.85) and the overweight (0.85 ⩽ WHR < 0.99) groups. Different associations of WHR and BMI with arterial stiffness among older adults should be further investigated.

Abstract
PURPOSE OF REVIEW Given that the life expectancy and the burden of hypertension are projected to increase over the next decade, hypertensive heart disease (HHD) may be expected to play an even more central role in the pathophysiology of cardiovascular disease (CVD). A broader understanding of the features and underlying mechanisms that constitute HHD therefore is of paramount importance. RECENT FINDINGS HHD is a condition that arises as a result of elevated blood pressure and constitutes a key underlying mechanism for cardiovascular morbidity and mortality. Historically, studies investigating HHD have primarily focused on left ventricular (LV) hypertrophy (LVH), but it is increasingly apparent that HHD encompasses a range of target-organ damage beyond LVH, including other cardiovascular structural and functional adaptations that may occur separately or concomitantly. HHD is characterized by micro- and macroscopic myocardial alterations, structural phenotypic adaptations, and functional changes that include cardiac fibrosis, and the remodeling of the atria and ventricles and the arterial system. In this review, we summarize the structural and functional alterations in the cardiac and vascular system that constitute HHD and underscore their underlying pathophysiology.
