Echocardiographic diagnosis and clinical implications of wide-open tricuspid regurgitation for evaluating right ventricular dysfunction in the emergency department. Am J Emerg Med 2024; 80:227.e7-227.e11. [PMID: 38702221 DOI: 10.1016/j.ajem.2024.04.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Accepted: 04/19/2024] [Indexed: 05/06/2024] Open
Abstract
The tricuspid regurgitation pressure gradient (TRPG) reflects the difference in pressure between the right ventricle and right atrium (ΔPRV-RA). Its estimation by echocardiography correlates well with that obtained using right-heart catheterization. An elevated TRPG is an important marker for identifying right ventricular dysfunction in both the acute and chronic settings. However, in the "wide-open" variant of TR, the TRPG counterintuitively falls. Failure to recognize this potential pitfall and underlying pathophysiology can cause underestimation of the severity of right ventricular dysfunction. This could lead to erroneous fluid tolerance assessments, and potentially harmful resuscitative and airway management strategies. In this manuscript, we illustrate the pathophysiology and potential pitfall of wide-open TR through a series of cases in which emergency physicians made the diagnosis using cardiac point-of-care ultrasound. To our knowledge, this clinical series is the first to demonstrate recognition of the paradoxically-low TRPG of wide-open TR, which guided appropriate management of critically ill patients in the emergency department.

Traditional and Advanced Echocardiographic Evaluation in Chronic Obstructive Pulmonary Disease: The Forgotten Relation. Am J Cardiol 2024; 217:102-118. [PMID: 38412881 DOI: 10.1016/j.amjcard.2024.02.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 01/22/2024] [Accepted: 02/12/2024] [Indexed: 02/29/2024]
Abstract
Chronic obstructive pulmonary disease (COPD) is a significant preventable and treatable clinical disorder defined by a persistent, typically progressive airflow obstruction. This disease has a significant negative impact on mortality and morbidity worldwide. However, the complex interaction between the heart and lungs is usually underestimated, necessitating more attention to improve clinical outcomes and prognosis. Indeed, COPD significantly impacts ventricular function, right and left chamber architecture, tricuspid valve functionality, and pulmonary blood vessels. Accordingly, more emphasis should be paid to their diagnosis since cardiac alterations may occur very early before COPD progresses and generate pulmonary hypertension (PH). Echocardiography enables a quick, noninvasive, portable, and accurate assessment of such changes. Indeed, recent advancements in imaging technology have improved the characterization of the heart chambers and made it possible to investigate the association between a few cardiac function indexes and clinical and functional aspects of COPD. This review aims to describe the intricate relation between COPD and heart changes and provide basic and advanced echocardiographic methods to detect early right ventricular and left ventricular morphologic alterations and early systolic and diastolic dysfunction. In addition, it is crucial to comprehend the clinical and prognostic significance of functional tricuspid regurgitation in COPD and PH and the currently available transcatheter therapeutic approaches for its treatment. Moreover, it is also essential to assess noninvasively PH and pulmonary resistance in patients with COPD by applying new echocardiographic parameters. In conclusion, echocardiography should be used more frequently in assessing patients with COPD because it may aid in discovering previously unrecognized heart abnormalities and selecting the most appropriate treatment to improve the patient's symptoms, quality of life, and survival.

Abstract
RATIONALE Pulmonary hypertension (PH) in COPD confers increased risk of exacerbations (ECOPD). Electrocardiogram (ECG) indicators of PH are prognostic both in PH and COPD. In the Beta-Blockers for the Prevention of Acute Exacerbations of COPD (BLOCK-COPD) trial, metoprolol increased risk of severe ECOPD through unclear mechanisms. OBJECTIVE We evaluated whether an ECG indicator of PH, P-pulmonale, would be associated with ECOPD and whether participants with P-pulmonale randomized to metoprolol were at higher risk of ECOPD and worsened respiratory symptoms given the potential detrimental effects of beta-blockers in PH. METHODS ECGs of 501 participants were analyzed for P-pulmonale (P wave enlargement in lead II). Cox proportional hazards models evaluated for associations between P-pulmonale and time to ECOPD (all and severe) for all participants and by treatment assignment (metoprolol vs. placebo). Linear mixed-effects models evaluated the association between treatment assignment and P-pulmonale on change in symptom scores (measured by CAT and SOBQ). RESULTS We identified no association between P-pulmonale and risk of any ECOPD or severe ECOPD. However, in individuals with P-pulmonale, metoprolol was associated with increased risk for ECOPD (aHR 2.92, 95% CI: 1.45-5.85). There was no association between metoprolol and ECOPD in individuals without P-pulmonale (aHR 1.01, 95% CI: 0.77-1.31). Individuals with P-pulmonale assigned to metoprolol experienced worsening symptoms (mean increase of 3.95, 95% CI: 1.32-6.58) whereas those assigned to placebo experienced a mean improvement in CAT score of -2.45 (95% CI: -0.30- -4.61). CONCLUSIONS In individuals with P-pulmonale, metoprolol was associated with increased exacerbation risk and worsened symptoms. These findings may explain the findings observed in BLOCK-COPD.

Alerhand S, Adrian RJ. What echocardiographic findings differentiate acute pulmonary embolism and chronic pulmonary hypertension? Am J Emerg Med 2023; 72:72-84.

Abstract
BACKGROUND Pulmonary embolism (PE) and pulmonary hypertension (PH) are potentially fatal disease states. Early diagnosis and goal-directed management improve outcomes and survival. Both conditions share several echocardiographic findings of right ventricular dysfunction. This can inadvertently lead to incorrect diagnosis, inappropriate and potentially harmful management, and delay in time-sensitive therapies. Fortunately, bedside echocardiography imparts a few critical distinctions. OBJECTIVE This narrative review describes eight physiologically interdependent echocardiographic parameters that help distinguish acute PE and chronic PH. The manuscript details each finding along with associated pathophysiology and summarization of the literature evaluating diagnostic utility. This guide then provides pearls and pitfalls with high-quality media for the bedside evaluation. DISCUSSION The echocardiographic parameters suggesting acute or chronic right ventricular dysfunction (best used in combination) are: 1. Right heart thrombus (acute PE) 2. Right ventricular free wall thickness (acute ≤ 5 mm, chronic > 5 mm) 3. Tricuspid regurgitation pressure gradient (acute ≤ 46 mmHg, chronic > 46 mmHg, corresponding to tricuspid regurgitation maximal velocity ≤ 3.4 m/sec and > 3.4 m/sec, respectively) 4. Pulmonary artery acceleration time (acute ≤ 60-80 msec, chronic < 105 msec) 5. 60/60 sign (acute) 6. Pulmonary artery early-systolic notching (proximally-located, higher-risk PE) 7. McConnell's sign (acute) 8. Right atrial enlargement (equal to left atrial size suggests acute, greater than left atrial size suggests chronic). CONCLUSIONS Emergency physicians must appreciate the echocardiographic findings and associated pathophysiology that help distinguish acute and chronic right ventricular dysfunction. In the proper clinical context, these findings can point towards PE or PH, thereby leading to earlier goal-directed management.

Right ventricular systolic strain in patients with pulmonary hypertension: clinical feasibility, reproducibility, and correlation with ejection fraction. J Echocardiogr 2023; 21:105-112. [PMID: 36451073 DOI: 10.1007/s12574-022-00593-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 10/22/2022] [Accepted: 11/11/2022] [Indexed: 12/05/2022]
Abstract
BACKGROUND Right ventricular (RV) systolic function is the major determinant of prognosis in patients with pulmonary hypertension (PH) with quantitative assessment by speckle-tracking strain echocardiography emerging as a viable candidate measure. METHOD We evaluated a prospective cohort of 231 patients with known or suspected PH referred for clinical echocardiography. All underwent measurement of RV free-wall systolic strain by sonographer staff. Digital images were recorded for blinded offline assessment by an expert echocardiographer. Reproducibility was assessed using the analysis methods of Bland-Altman and the Cohen's-Kappa coefficient. RESULTS RV strain was feasible in 213 (92%). The average RV systolic pressure was 59 ± 22 mmHg. RV systolic strain correlated with functional class, NT-proBNP, and the degree of RV enlargement. The average free-wall systolic strain was - 20 ± 7% (range - 2 to - 37%). The RV strain measures (clinical practice versus blinded expert) had an excellent correlation with a normal distribution (R2 0.87, p < 0.0001). By Bland-Altman analysis, the mean difference in measurement was - 1.7% (95% CI - 1.4 to - 2.1) with a correlation of 0.93, p value of < 0.0001. The reproducibility of RV strain for clinically relevant thresholds was also excellent (Kappa coefficients 0.68-0.83). There was no effect on the variability of strain measures across body mass, pulmonary pressures, or rhythm. RV strain correlated with RV diastolic volumes and ejection fraction with RV free wall strain being the best echo predictor for a reduction in ejection fraction. CONCLUSION Here RV systolic strain was found to be highly feasible and reproducible in clinical practice with excellent levels of agreement for clinically relevant thresholds.

Abstract
PURPOSE The purpose of this study was to evaluate and confirm the prognostic utility of comprehensive transthoracic echocardiography (TTE) using offline myocardial strain analyses in a Japanese coronavirus disease (COVID-19) cohort hospitalized in intensive care units. METHODS We performed a retrospective analysis of 90 consecutive adult patients with COVID-19 who underwent clinically indicated standard two-dimensional TTE in intensive care wards. Patients on extracorporeal membrane oxygenation (ECMO) at the time of TTE were excluded. Biventricular strain assessments using vendor-independent offline speckle tracking analysis were performed. Patients with inadequate TTE image quality were also excluded. RESULTS Among the 90 COVID-19 patients, 15 (17%) patients required venovenous or venoarterial ECMO. There were 25 (28%) in-hospital deaths. A composite event, defined as the combination of in-hospital mortality and subsequent initiation of ECMO, occurred in 32 patients. Multivariate logistic regression for composite events indicated that right ventricular free wall longitudinal strain (RV-FWLS) and mechanical ventilation at the time of TTE were independent risk factors for composite events (p = 0.01, odds ratio [OR] 1.09, 95% confidence interval [CI] 1.01-1.18; p = 0.04, OR 3.24, 95% CI 1.03-10.20). Cumulative survival probability plots generated using the Kaplan-Meier method for composite events with log-rank tests revealed a significant difference between subgroups divided by the cutoff value of RV-FWLS (p < 0.001). CONCLUSION Offline measurement of RV-FWLS may be a potent predictor of worse outcomes in COVID-19 requiring intensive care. Larger multicenter prospective studies are needed.

Abstract
BACKGROUND Post intubation cardiac arrest and hemodynamic instability are serious adverse events encountered in critically ill patients. The association of pre-existing right ventricular (RV) dysfunction with post intubation cardiac arrest and hemodynamic instability in critically ill patients is unknown. METHODS This is a retrospective matched cohort study of adult critically ill patients who underwent intubation from July 2016 to December 2019. The study was conducted at a quaternary medical center in Houston, Texas. A total of 340 critically ill patients who underwent intubation in the intensive care units, wards, and the emergency room were included. The study cohort was categorized into 4 groups based on the pre-existing RV function: normal function, mild dysfunction, moderate dysfunction, and severe dysfunction. Cardiac arrest and/or hemodynamic instability within one hour post intubation were the primary study outcomes. Secondary outcomes included in hospital and 60-day mortality. RESULTS Study patients were of mean age of 61.95 ± 14.28 years, including 132 (39%) females and 208 (61%) males. The primary outcomes were significantly worse in mild, moderate, and severe RV dysfunction groups compared to the normal RV function group (34.12%-P = 0.014, 47.06%-P < 0.001, 51.67%-P < 0.001, vs. 17.56%). In a multivariable logistic regression analysis, pre-existing moderate (OR = 2.65, P = 0.013) and severe RV dysfunction groups (OR = 2.66, P = 0.015) were associated with statistically significant higher cardiac arrest and hemodynamic instability post intubation. Pre-existing severe RV dysfunction was associated with statistically significant higher in hospital mortality (62.35%-P < 0.001). The multivariable Cox-regression analysis showed that pre-existing severe RV dysfunction was associated with a statistically significant higher 60-day mortality (HR = 2.57, P = 0.001). CONCLUSIONS Pre-existing moderate and severe RV dysfunctions were independently associated with significantly higher cardiac arrest and/or hemodynamic instability post intubation in critically ill patients. Pre-existing RV function may serve as a mortality predictor in critically ill patients undergoing endotracheal intubation.

Abstract
BACKGROUND Lung hyperinflation and systemic inflammation are currently believed to be the most important causes of right heart alterations in chronic obstructive pulmonary disease (COPD) patients. A multicentre observational study was performed to assess the morphological and functional parameters of right ventricle (RV) in COPD subjects, as well as to evaluate the potential prognostic impact on the development of major cardiovascular adverse events (MACEs). METHODS For this retrospective study, from 1 January 2010 to 31 December 2021, we enrolled COPD patients on the basis of their airflow limitation. In particular, we selected subjects spanning across GOLD 1 and 2 functional stages. Clinical, laboratory and functional parameters were collected at baseline. Echocardiography was routinely performed in all COPD patients. RV dysfunction was defined on the basis of tricuspid annular plane systolic excursion (TAPSE) values. MACE occurrence (non-fatal ischemic stroke, non-fatal myocardial infarction, cardiac revascularization or coronary bypass surgery and cardiovascular death) was evaluated during a median follow-up of 55 (36-72) months. RESULTS Among the 749 enrolled patients, 408 subjects had a TAPSE value ≥20 mm, while the remaining 341 had a TAPSE value <20 mm. In patients with TAPSE ≥20 mm the observed MACEs were 1.9 events/100 patient-year, while in the group with a worse right heart function there were 4.2 events/100 patient-year (p < .0001). The multivariate analysis model confirmed the association between RV dysfunction and MACE. Indeed, a 1-mm increase in TAPSE value and the intake of long-acting β2 -receptor agonists (LABA)/long-acting muscarinic antagonist (LAMA) inhaled therapy were protective factors for the onset of MACE, while the presence of diabetes mellitus and high values of both uric acid (UA) and systolic pulmonary arterial pressure (S-PAP) enhanced the risk of MACE in study participants. CONCLUSIONS The results of this study showed that in patients with mild COPD there is an association between right heart dysfunction and the risk of MACE during follow-up.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by thrombotic obstruction of the pulmonary arteries, and right ventricular (RV) dysfunction is a major cause of death. Cardiac magnetic resonance (CMR) is the gold standard for assessing heart wall deformation; therefore, we aimed to determine the prognostic value of CMR strain in patients with CTEPH. Strain derived by CMR was measured at the time of diagnosis in 45 patients with CTEPH, and the relationship between RV strain and prognosis was determined through follow-up. The value of RV strain in the prognostic model was compared with that of pulmonary arterial hypertension (PAH) risk stratification. The RV global peak longitudinal strain (GLS) and global peak circumferential strain (GCS) in CTEPH patients were lower than the normal references of RV strain in the control group. GLS and longitudinal strain in the basal segment were independent risk factors for adverse events (P < .050). Adding CMR parameters to PAH risk stratification improved its predictive power in patients with CTEPH. GLS and GCS scores were impaired in patients with chronic RV overload. RV strain derived by CMR imaging is a promising noninvasive tool for the follow-up of patients with CTEPH.

Abstract
OBJECTIVE Patients with COPD are prone to cardiac remodeling; however, little is known about cardiac function in patients recovering from an acute exacerbation of COPD (AECOPD) and its association with exercise capacity. The aim of this study was to evaluate the cardiac function and structure and to compare their relationship with exercise capacity in patients with a recent AECOPD and patients with clinically stable COPD. METHODS This was a cross-sectional study including 40 COPD patients equally divided into two groups: recent AECOPD group (AEG) and clinically stable COPD group (STG). Echocardiography was performed to assess cardiac function and chamber structure. The six-minute walk distance (6MWD) and the Duke Activity Status Index (estimated Vo2) were used in order to assess exercise capacity. RESULTS No significant differences in cardiac function and structure were found between the groups. The 6MWD was associated with early/late diastolic mitral filling velocity ratio (r = 0.50; p < 0.01), left ventricular posterior wall thickness (r = -0.33; p = 0.03), and right atrium volume index (r = -0.34; p = 0.04), whereas Vo2 was associated with right atrium volume index (r = -0.40; p = 0.02). CONCLUSIONS Regardless of the clinical condition (recent AECOPD vs. stable COPD), the cardiac function and structure were similar between the groups, and exercise capacity (determined by the 6MWD and Vo2) was associated with cardiac features.

Abstract
AIMS The European Association of Cardiovascular Imaging (EACVI) Scientific Initiatives Committee performed a global survey to evaluate the use of different cardiac imaging modalities for the evaluation of the right heart. METHODS AND RESULTS Delegates from 250 EACVI registered centres were invited to participate in a survey which was also advertised on the EACVI bulletin and on social media. One hundred and thirty-eight respondents from 46 countries across the world responded to the survey. Most respondents worked in tertiary centres (79%) and echocardiography was reported as the commonest imaging modality used to assess the right ventricle (RV). The majority of survey participants (78%) included RV size and function in >90% of their echocardiographic reports. The RV basal diameter obtained from the apical four-chamber view and the tricuspid annular plane systolic excursion were the commonest parameters used for the echocardiographic assessment of RV size and function as reported by 82 and 97% respondents, respectively. Survey participants reported arrhythmogenic cardiomyopathy as the commonest condition (88%) where cardiac magentic resonance (CMR) imaging was used for right heart assessment. Only 52% respondents included RV volumetric and ejection fraction assessments routinely in their CMR reports, while 30% of respondents included these parameters only when RV pathology was suspected. Finally, 73% of the respondents reported pulmonary hypertension as the commonest condition where right heart catheterization was performed. CONCLUSION Echocardiography remains the most frequently used imaging modality for the evaluation of the right heart, while the use of other imaging techniques, most notably CMR, is increasing.

Abstract
IntroductionAccurate assessment of right ventricular (RV) systolic function has prognostic and therapeutic implications in many disease states. Echocardiography remains the most frequently deployed imaging modality for this purpose, but estimation of RV systolic function remains challenging. The purpose of this study was to evaluate the diagnostic performance of a novel measurement of RV systolic function called lateral annular systolic excursion ratio (LASER), which is the fractional shortening of the lateral tricuspid annulus to apex distance, compared to right ventricular ejection fraction (RVEF) derived by cardiac magnetic resonance imaging (CMR).MethodsA retrospective cohort of 78 consecutive patients who underwent clinically indicated CMR and transthoracic echocardiography within 30 days were identified from a database. Parameters of RV function measured included: tricuspid annular plane systolic excursion (TAPSE) by M-mode, tissue Doppler S', fractional area change (FAC) and LASER. These measurements were compared to RVEF derived by CMR using Pearson's correlation coefficients and receiver operating characteristic curves.ResultsLASER was measurable in 75 (96%) of patients within the cohort. Right ventricular systolic dysfunction, by CMR measurement, was present in 37% (n = 29) of the population. LASER has moderate positive correlation with RVEF (r = 0.54) which was similar to FAC (r = 0.56), S' (r = 0.49) and TAPSE (r = 0.37). Receiver operating characteristic curves demonstrated that LASER (AUC = 0.865) outperformed fractional area change (AUC = 0.767), tissue Doppler S' (AUC = 0.744) and TAPSE (AUC = 0.645). A cohort derived dichotomous cutoff of 0.2 for LASER was shown to provide optimal diagnostic characteristics (sensitivity of 75%, specificity of 87% and accuracy of 83%) for identifying abnormal RV function. LASER had the highest sensitivity, accuracy, positive and negative predictive values among the parameters studied in the cohort.ConclusionsWithin the study cohort, LASER was shown to have moderate positive correlation with RVEF derived by CMR and more favorable diagnostic performance for detecting RV systolic dysfunction compared to conventional echocardiographic parameters while being simple to obtain and less dependent on image quality than FAC and emerging techniques.

Abstract
BACKGROUND The echocardiogram is a useful method for monitoring the cardiovascular complications of chronic obstructive pulmonary disease (COPD), but it is not clear if morphological and functional cardiac variables are able to identify patients with unfavorable COPD progression. OBJECTIVE The aim of this study was to investigate morphological and functional echocardiographic variables associated with exacerbation of the disease, pulmonary function parameters and functional capacity evaluation in COPD patients. METHOD A longitudinal observational study including 91 patients diagnosed with COPD, who were stratified in two groups according to their basal right ventricle diastolic diameter (RVDD) measuring greater and less than 35 mm. They underwent clinical evaluation, echocardiography, spirometry and 6-minute walking-test (6MWT). RESULTS The study found that patients with RVDD greater than 35 mm showed worse functional capacity in the 6MWT (p = 0.05) and more exacerbation of the disease during the one-year follow-up (p = 0.05). There were correlations of greater RVDD vs forced vital capacity (R = -0.27; p = 0.02) and distance in the 6MWT (R = 0.55; p = 0.03) in patients with exacerbation. In the univariate regression analysis, the RVDD was responsible for 55% of the variation in distance in the 6MWT (-0.75 m) in COPD patients. CONCLUSION The RV dilation is associated with unfavorable prognostic markers in COPD, such as the worsening of the functional capacity and more frequent exacerbations. The echocardiogram may be a useful tool to identify patients who need more aggressive strategies to control the evolution of the disease with potential impact in pulmonary rehabilitation.

Abstract
BACKGROUND Cardiac Magnetic Resonance Imaging (cMRI) is the gold standard for right ventricular (RV) assessment due to its high spatial resolution. The American Society of Echocardiography (ASE) recommends eight structural and six functional quantitative parameters for evaluation of the RV. This study sought to simplify echocardiographic RV assessment by examining the relative diagnostic value of the echo recommended parameters by applying them to cMRI imaging of the RV. METHODS We applied ASE recommended measures of RV size and function to 56 cMRI's and compared them to RV volumetric analysis obtained from cMRI. Pearsons' correlation coefficient was used to compare ASE prescribed parameters to corresponding cMRI calculated RV end diastolic volume (RVEDV) and RV ejection fraction (RVEF). The diagnostic performance of each parameter in predicting abnormal RV size or function was analyzed using receiver operator characteristic curves. Youden-J index was used to determine optimal sensitivity/specificity cut-points. Stepwise regression modeling was performed to identify measurements independently associated with RV size or RVEF. RESULTS RV end diastolic area (RVEDA) correlated best with RVEDV (r = .76, p < 0.001) and RV fractional area change (RVFAC) correlated best with RVEF (r = .7, p < 0.001). The best ASE parameter for identifying RV dilatation was RVEDA (Youden-J index = .84), the optimal cutoff was 32.3 cm2 which yielded sensitivity/specificity of 84% and 100%, respectively. The best parameter for diagnosing RV dysfunction was RVFAC (Youden-J index = .52), with an optimal cutoff of 42% leading to sensitivity/specificity of 64% and 88%, respectively. CONCLUSION The area based echocardiographic parameters for RV size and function, RVEDA and RV fractional area change outperform linear measurements in predicting RV dilation and RV systolic dysfunction. These parameters should be examined in further echocardiographic based studies as the primary parameters to guide quantitative RV assessment.

Abstract
Randomized trials of pulmonary vasodilators in pulmonary hypertension due to left heart disease (Group 2) and lung disease (Group 3) have demonstrated potential for harm. Yet these therapies are commonly used in practice. Little is known of the effects of treatment outside of clinical trials. We aimed to establish outcomes of vasodilator treatment for Groups 2/3 pulmonary hypertension in real-world practice. We conducted a retrospective cohort study of 132,552 Medicare-eligible Veterans with incident Groups 2/3 pulmonary hypertension between 2006 and 2016, and a secondary nested case-control study. Our primary outcome was a composite of death by any cause or selected acute organ failures. In our cohort analysis, we calculated adjusted risks of time to our outcome using Cox proportional hazards models with facility-specific random effects. In our case-control analysis, we used logistic mixed-effects models to estimate the effect of any past, recent, and cumulative exposure on our outcome. From our cohort study, 3249 (2.5%) Veterans were exposed to pulmonary vasodilators. Exposure to vasodilators was associated with increased risk of our primary outcome, in both Group 3 (HR: 1.58 (95% CI: 1.37-1.82)) and Group 2 (HR: 1.26 (95% CI: 1.12-1.41)) pulmonary hypertension patients. The case-control study determined odds of our outcome increased by 11% per year of exposure (OR: 1.11 (95% CI: 1.07-1.16)). Treating Groups 2/3 pulmonary hypertension with vasodilators in clinical practice is associated with increased risk of harm. This extension of trial findings to a real-world setting offers further evidence to limit use of vasodilators in Groups 2/3 pulmonary hypertension outside of clinical trials.

[PMID: 33568904 PMCID: PMC7868200 DOI: 10.2147/copd.s285812] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Accepted: 12/21/2020] [Indexed: 11/23/2022] Open
Abstract
Aim Our aim was to assess: 1) the impact of the eccentric left ventricular hypertrophy (ELVH) on exercise performance in patients diagnosed with chronic heart failure (CHF) alone and in patients with co-existing CHF and chronic obstructive pulmonary disease (COPD) and 2) the relationship between left and right cardiac function measurements obtained by doppler echocardiography, clinical characteristics and primary measures of cardiorespiratory fitness. Methods The current study included 46 patients (CHF:23 and CHF+COPD:23) that performed advanced pulmonary function tests, echocardiography and symptom-limited, incremental cardiopulmonary exercise testing (CPET) on a cycle ergometer. Results Patients with CHF+COPD demonstrated a lower work rate, peak oxygen uptake (VO2), oxygen pulse, rate pressure product (RPP), circulatory power (CP) and ventilatory power (VP) compared to those only diagnosed with CHF. In addition, significant correlations were observed between VP and relative wall thickness (r: 0.45 p: 0.03),VE/VCO2 intercept and Mitral E/e' ratio (r: 0.70 p: 0.003) in the CHF group. Significant correlations were found between indexed left ventricle mass and RPP (r: -0.47; p: 0.02) and relative VO2 and right ventricle diameter (r: -0.62; p: 0.001) in the CHF+COPD group. Conclusion Compared to a diagnosis of CHF alone, a combined diagnosis of CHF+COPD induced further impairments in cardiorespiratory fitness. Moreover, echocardiographic measures of cardiac function are related to cardiopulmonary exercise performance and therefore appear to be an important therapeutic target when attempting to improve exercise performance and functional capacity.

Abstract
OBJECTIVE To evaluate the changes of cardiac structure and function and their risk factors in elderly patients with obstructive sleep apnea syndrome (OSA) without cardiovascular complications. METHODS Eighty-two elderly OSA patients without cardiovascular disease admitted between January, 2015 and October, 2016 were enrolled in this study. According to their apnea-hypopnea index (AHI, calculated as the average number of episodes of apnoea and hypopnoea per hour of sleep), the patients were divided into mild OSA group (AHI < 15) and moderate to severe OSA group (AHI ≥ 15). The demographic data and the general clinical data were recorded and fasting blood samples were collected from the patients on the next morning following polysomnographic monitoring for blood cell analysis and biochemical examination. Echocardiography was performed within one week after overnight polysomnography, and the cardiac structure, cardiac function and biochemical indexes were compared between the two groups. RESULTS Compared with those with mild OSA group, the patients with moderate to severe OSA had significantly higher hematocrit (0.22±0.08 vs 0.17±0.04, P=0.032) and serum creatinine level (70.94± 27.88 vs 54.49±34.22 μmol/L, P=0.022). The left ventricular ejection fraction, interventricular septal thickness, left ventricular posterior wall thickness, left atrial diameter and left ventricular end-diastolic diameter were all similar between the two groups. With a similar early diastolic mitral flow velocity (E) between the two groups, the patients with moderate to severe OSA had a significantly higher late diastolic mitral flow velocity (A) (70.35±6.87 vs 64.09±8.31, P=0.0001) and a significantly lower E/A ratio (0.98±0.06 vs 1.08±0.05, P=0.0001) than the patients with mild OSA. Multiple linear regression showed that the E/A ratio was negatively correlated with AHI (β =- 0.645, P=0.0001). CONCLUSIONS Cardiac diastolic function impairment may occur in elderly patients with moderate or severe OSA who do not have hypertension or other cardiovascular diseases, and the severity of the impairment is positively correlated with AHI.

Abstract
Right ventricular (RV) function is important for clinical status and outcomes in children and adults with congenital heart disease (CHD). In the normal RV, longitudinal systolic function is the major contributor to global RV systolic function. A variety of factors contribute to RV failure including increased pressure- or volume-loading, electromechanical dyssynchrony, increased myocardial fibrosis, abnormal coronary perfusion, restricted filling capacity and adverse interactions between left ventricle (LV) and RV. We discuss the different imaging techniques both at rest and during exercise to define and detect RV failure. We identify the most important biomarkers for risk stratification in RV dysfunction, including abnormal NYHA class, decreased exercise capacity, low blood pressure, and increased levels of NTproBNP, troponin T, galectin-3 and growth differentiation factor 15. In adults with CHD (ACHD), fragmented QRS is independently associated with heart failure (HF) symptoms and impaired ventricular function. Furthermore, we discuss the different HF therapies in CHD but given the broad clinical spectrum of CHD, it is important to treat RV failure in a disease-specific manner and based on the specific alterations in hemodynamics. Here, we discuss how to detect and treat RV dysfunction in CHD in order to prevent or postpone RV failure.

Abstract
Background Recognizing low right ventricular (RV) function from 2-dimentiontial echocardiography (2D-ECHO) is challenging when parameters are contradictory. We aim to develop a model to predict low RV function integrating the various 2D-ECHO parameters in reference to cardiac magnetic resonance (CMR)-the gold standard. Methods We retrospectively identified patients who underwent a 2D-ECHO and a CMR within 3 months of each other at our institution (American University of Beirut Medical Center). We extracted three parameters (TAPSE, S' and FACRV) that are classically used to assess RV function. We have assessed the ability of 2D-ECHO derived parameters and clinical features to predict RV function measured by the gold standard CMR. We compared outcomes from four machine learning algorithms, widely used in the biomedical community to solve classification problems. Results One hundred fifty-five patients were identified and included in our study. Average age was 43±17.1 years old and 52/156 (33.3%) were females. According to CMR, 21 patients were identified to have RV dysfunction, with an RVEF of 34.7%±6.4%, as opposed to 54.7%±6.7% in the normal RV population (P<0.0001). The Random Forest model was able to detect low RV function with an AUC =0.80, while general linear regression performed poorly in our population with an AUC of 0.62. Conclusions In this study, we trained and validated an ML-based algorithm that could detect low RV function from clinical and 2D-ECHO parameters. The algorithm has two advantages: first, it performed better than general linear regression, and second, it integrated the various 2D-ECHO parameters.

Abstract
Right ventricular (RV) size and function are important predictors of cardiovascular morbidity and mortality in patients with various conditions. However, non-invasive assessment of the RV is a challenging task due to its complex anatomy and location in the chest. Although conventional echocardiography is widely used, its limitations in RV assessment are well recognised. New techniques such as three-dimensional and speckle tracking echocardiography have overcome the limitations of conventional echocardiography allowing a comprehensive, quantitative assessment of RV geometry and function without geometric assumptions. Cardiac magnetic resonance (CMR) and CT provide accurate assessment of RV geometry and function, too. In addition, tissue characterisation imaging for myocardial scar and fat using CMR and CT provides important information regarding the RV that has clinical applications for diagnosis and prognosis in a broad range of cardiac conditions. Limitations also exist for these two advanced modalities including availability and patient suitability for CMR and need for contrast and radiation exposure for CT. Hybrid imaging, which is able to integrate anatomical information (usually obtained by CT or CMR) with physiological and molecular data (usually obtained with positron emission tomography), can provide optimal in vivo evaluation of Rv functional impairment. This review summarises the clinically useful applications of advanced echocardiography techniques, CMR and CT for comprehensive assessment of RV size, function and mechanics.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is associated with structural and mechanical changes in the pulmonary vascular bed that increase right ventricular (RV) afterload and subsequently right heart failure. OBJECTIVES The aim of the study was to elucidate RV dysfunction at rest by echocardiography in a cohort of COPD patients and to study its impact on prognosis. METHODS 84 patients of COPD and 40 matching healthy controls were evaluated at baseline. Evaluation included clinical examination, pulmonary function tests; 6 minutes walk test and echocardiography. Patient with COPD were again evaluated after 6 months. RESULTS All echocardiographic parameters of RV function were significantly impaired in COPD patients as compared to controls. Clinical deterioration in COPD group was much more in patients with baseline abnormal RV function (89%) and patients with RV systolic pressure ≥35 mmHg (P = 0.018). All the six patients who died had three or more abnormal RV systolic function parameters. CONCLUSIONS RV myocardial performance index and basal strain showed largest difference between controls and COPD cases. Clinical deterioration was more common in patients with abnormal RV function parameters and pulmonary hypertension.

Abstract
BACKGROUND Right ventricular (RV) function is a prognostic marker of chronic thromboembolic pulmonary hypertension (CTEPH). We used two-dimensional (2D) speckle-tracking echocardiography (STE) to evaluate the therapeutic effects of balloon pulmonary angioplasty (BPA) in CTEPH patients. METHODS A total of 46 CTEPH patients who underwent 2D STE before and after BPA were enrolled in this retrospective study. The following RV functional parameters were measured: tricuspid annular plane systolic excursion (TAPSE), right ventricular fractional area change (RVFAC), RV index of myocardial performance (RIMP), and free wall longitudinal strain (RVFWLS). Satisfactory BPA was defined as mean pulmonary arterial pressure (mPAP) <25 mm Hg or improvement in mPAP > 10 mm Hg after BPA. Patients were divided into two groups according to mPAP values: group I had satisfactory BPA outcomes; group Ⅱ had unsatisfactory BPA outcomes. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was used to determine the optimal cutoff values and the ability of RVFWLS to predict successful BPA outcomes. RESULTS After BPA, SPAP measured by echocardiography (SPAPecho ) and RIMP decreased, but TAPSE, RVFAC, and RVFWLS increased. Before BPA, group Ⅰ had significantly better RV function than group Ⅱ. Multifactor logistic regression analysis identified RVFWLS as an independent factor associated with satisfactory BPA outcomes. The optimal cutoff value for RVFWLS in predicting satisfactory BPA outcomes was -12.2%. CONCLUSIONS Balloon pulmonary angioplasty improves RV function in CTEPH patients. RVFWLS is a valuable noninvasive tool with which to assess the treatment effects of BPA. CTEPH patients with lower RVFWLS may have limited benefit from BPA.

A novel index equivalent to the myocardial performance index for right ventricular functional assessment in children and adolescent patients. Sci Rep 2019; 9:19975.

Abstract
The aims of the present study were to develop and check the utility and feasibility of a novel right ventricular (RV) functional index (RV angular velocity; RVω, s−1) derived from the angular velocity in harmonic oscillator kinematics obtained from the RV pressure waveform. We hypothesized that RVω reflects the myocardial performance index (MPI), which represents global RV function. A total of 132 consecutive patients, ranging in age from 3 months to 34 years with various cardiac diseases were included in this prospective study. RVω was defined as the difference between the peak derivative of pressure (dP/dt_max − dP/dt_min) divided by the difference between the maximum and minimum pressure (Pmax – Pmin). RVω showed significant negative correlations with the pulsed-wave Doppler-derived myocardial performance index (PWD-MPI) and the tissue Doppler imaging-derived MPI (TDI-MPI) (r = −0.52 and −0.51, respectively; both p < 0.0001). RVω also showed significant positive correlations with RV fractional area change (RVFAC) and RV ejection fraction (RVEF) (r = 0.41 and 0.39, respectively; both p < 0.0001), as well as a significant negative correlation with tricuspid E/e′ (r = −0.19, p = 0.0283). The clinical feasibility and utility of RVω for assessing global RV performance, incorporating both systolic and diastolic function, were demonstrated.

Abstract
BACKGROUND Right ventricle (RV) evaluation requires dedicated imaging to achieve a comprehensive functional and anatomical assessment. Right ventricular imaging could be technically difficult which results in suboptimal visibility and inconsistent assessment between observers. The aim of this study was to assess feasibility and the additive value of contrast enhancement for right ventricular evaluation. METHODS Eighty patients referred for clinically indicated echocardiography studies were included. Patients with irregular rhythms were excluded. Dedicated RV-focused view was attained; RV dimensions measured, and RV segment visualization and wall motion were assessed with and without contrast enhancement. Paired sample t test was used to compare continuous variables, Wilcoxon signed-rank test to compare segments visualization on enhanced versus (vs) nonenhanced images, and Cohen kappa coefficient to assess the agreement of wall motion between two observers. Reproducibility was measured by the absolute mean difference method. RESULTS A total of 240 total segments of 80 patients were analyzed, and 178 (74%) were visible on unenhanced while 221 (92%) on enhanced images, P < .05. Further, RV measurements on enhanced images were consistently larger on RV focused, SAX, and RVOT. Inter- and intra-observer reproducibility showed a higher reproducibility with a lower bias on enhanced images. Absolute agreement on RV segmental wall motion between two independent observers was higher on enhanced images. Percent agreement was 78% on UE vs 89% on CE. CONCLUSION Contrast RV imaging is feasible and improves RV segment visualization and inter-observer agreement. Compared with unenhanced images, RV measurements on contrast images are larger and more reproducible with lower bias.

Abstract
INTRODUCTION Idiopathic pulmonary fibrosis (IPF) and chronic obstructive pulmonary disease (COPD) show poor prognosis. The importance of left (LV) and right (RV) ventricular morphology and function in patients with end-stage lung diseases referred for lung transplantation (LT) is not well established. OBJECTIVES To assess whether LV and RV echocardiographic parameters influence survival of patients with IPF, COPD and other interstitial lung diseases (ILD) awaiting LT. METHODS In 65 patients (20 patients with COPD, 37 with IPF and 8 with other ILD), we performed transthoracic echocardiography and right heart catheterization. Echocardiographic parameters were assessed with regard to 1-year all-cause mortality. RESULTS The mortality rate was higher in patients with smaller dimensions of LV end-systolic (LVESD) and end-diastolic (LVEDD) diameter (HR 3.03, 95% CI 1.16-7.69, P = .023; and HR 2.9, 95% CI 1.16-7.14, P = .022; respectively), higher RV-to-LV (RV/LV-4CH) ratio (HR 7.6, 95% CI 1.6-29.5, P = .009) and RV proximal outflow tract (RVOT-PLAX) dilatation (HR 2.69, 95% CI 1.22-5.96, P = .015). These associations were independent of age, gender, body mass index, VC, FEV1% and pulmonary diagnosis. The subanalysis of IPF patients demonstrated that the smaller LVESD and LVEDD increased mortality rate (HR 15.0, 95% CI 2.87-89.72, P = .003; HR 4.95, 95% CI 1.5-15.5, P = .006; respectively). No such associations were found in the COPD patients. CONCLUSION LV echocardiographic parameters (LVESD or LVEDD) are useful in predicting survival in patients with end-stage lung diseases, mainly in IPF patients awaiting LT. Other parameters (RV/LV-4CH and RVOT-PLAX dilatation) may also influence survival.

Abstract
Sigmoid-shaped ventricular septum (SS), a frequently encountered minor abnormality in echocardiographic examinations of the elderly, may have some influence on RV shape. We aimed to determine the influence of SS on the accuracy of the 6 RV linear diameter measurements in the light of three-dimensional echocardiographic (3DE) RV volume. The aorto-septal angle (ASA) was measured in the parasternal long-axis view using two-dimensional echocardiography (2DE) as an index of SS in 70 patients without major cardiac abnormalities who were subdivided into 35 with SS (ASA ≤ 120°) and 35 without SS (NSS). We measured RV end-diastolic volume (RVEDV) using 3DE; in addition, using 2DE, we measured basal RV diameter, mid-cavity diameter, longitudinal diameter and end-diastolic area in the apical four-chamber view; proximal RV outflow tract (RVOT) diameter in the parasternal long-axis view; and proximal and distal RVOT diameters in the parasternal short-axis view. RVEDV did not differ between the SS and NSS groups. The SS group had greater basal RV diameter and proximal and distal RVOT diameters than the NSS group. RV mid-cavity diameter, longitudinal diameter, and end-diastolic area did not differ between the groups. Among the 2DE parameters of RV size, RV end-diastolic area was most strongly correlated with RVEDV (r = 0.67), followed by RV mid-cavity diameter (r = 0.58). When SS is present, the echocardiographic basal RV diameter and RVOT diameters overestimate RV size, and the measurement of RV end-diastolic area and mid-cavity diameter more correctly reflect 3D RV volume.

Abstract
Pulmonary hypertension (PH) is defined as resting mean pulmonary artery pressure ≥ 25 mmHg and is caused by multiple etiologies including heart, lung or other systemic diseases. Evaluation of right ventricular (RV) function in PH is very important to plan treatment and determine prognosis. However, quantification of volume and function of the RV remains difficult due to complicated RV geometry. A number of imaging tools has been utilized to diagnose PH and assess RV function. Each imaging technique including conventional echocardiography, three-dimensional echocardiography, strain echocardiography, computed tomography and cardiac magnetic resonance imaging has-advantages and limitations and can provide unique information. In this article, we provide a comprehensive review of the utility, advantages and shortcomings of the multimodality imaging used to evaluate patients with PH.

Abstract
Pressure overload of the right ventricle (RV) in pulmonary arterial hypertension (PAH) leads to RV remodeling and failure, an important determinant of outcome in patients with PAH. Several G protein-coupled receptors (GPCRs) are differentially regulated in the RV myocardium, contributing to the pathogenesis of RV adverse remodeling and dysfunction. Many pharmacological agents that target GPCRs have been demonstrated to result in beneficial effects on left ventricular (LV) failure, such as beta-adrenergic receptor and angiotensin receptor antagonists. However, the role of such drugs on RV remodeling and performance is not known at this time. Moreover, many of these same receptors are also expressed in the pulmonary vasculature, which could result in complex effects in PAH. This manuscript reviews the role of GPCRs in the RV remodeling and dysfunction and discusses activating and blocking GPCR signaling to potentially attenuate remodeling while promoting improvements of RV function in PAH.

Abstract
Our aim was (1) to determine the within-day and between-day variability of several indices of systolic and diastolic right ventricular (RV) function by using conventional echocardiography and speckle-tracking echocardiography (STE) (Study 1), (2) to quantify these variables in a large healthy canine population (n = 104) with Doppler-derived estimated systolic pulmonary arterial pressure (SPAP) and left ventricular (LV) function, and (3) to establish the corresponding reference intervals (Study 2). For both studies, RV variables included tricuspid annular plane systolic excursion (TAPSE), right fractional area change (RFAC), STE longitudinal systolic strain (StS) of the RV free wall (RVFW) and of the entire RV (i.e., global RV StS), STE longitudinal systolic RVFW strain rate (SRS), and the diastolic early:late strain rate ratio. All but one within- and between-day coefficients of variation (13/14) were < 15%, the lowest being observed for TAPSE (3.6–9.8%), global RV StS (3.8–9.9%), and RVFW StS (3.7–7.3%). SPAP was weakly and negatively correlated with the TAPSE:body weight ratio (rs = −0.26, p = 0.01) and RVFW SRS (rs = −0.23, p < 0.05). Reference intervals (lower and upper limits with 90% confidence intervals) were provided for all variables. STE provides a non-invasive evaluation of RV function that may be used for clinical investigations in canine cardiology.

Abstract
Pulmonary hypertension due to left heart disease (PH-LHD) is caused by left ventricular (LV) systolic and/or diastolic dysfunction and left heart valve disease. LV diseases lead to left ventricular filling pressure increases, pulmonary venous obstruction and pulmonary venous pressure increases, and thus to secondary PH. Exercise tolerance is lower and fatality rates are higher in patients with PH-LHD than those in subjects with normal pulmonary arterial pressure. In spite of the progress in the study of the mechanisms of PH-LHD in recent years, no specific treatment is currently available. The efficacy and safety of targeted therapies for pulmonary arterial hypertension remain to be fully established. In the present study, PH-LHD patients were treated with milrinone injection. It was concluded that milrinone significantly reduces pulmonary artery systolic pressure (PASP) in patients with PH-LHD, and significantly improves the cardiac structure, cardiac function and biochemical indexes. PASP was significantly correlated with the left atrial diameter, LV end diastolic diameter, LV ejection fraction, tricuspid annular plane systolic excursion, right ventricular fractional area change, N-terminal pro-B-type natriuretic peptide and hypersensitive C-reactive protein.

Abstract
BACKGROUND Kawasaki disease (KD) is known as systemic vasculitis, and more than half of the patients with KD have myocarditis, which can induce ventricular dysfunction. In this study, we evaluate left ventricular (LV) dysfunction in patients with KD based on the myocardial performance index (MPI) using pulse Doppler (PD) and tissue Doppler imaging (TDI), from the acute to convalescent phases. METHODS We retrospectively studied 89 children diagnosed with KD from January 2010 to August 2012. We assessed the presence of coronary artery lesions (CALs) and the LV ejection fraction, PD-MPI, and TDI-MPI at diagnosis, and 2, 14, and 56 days after intravenous immunoglobulin (IVIG) treatment. We enrolled 70 healthy children as a control group. RESULTS The ejection fraction in patients with KD at diagnosis (67.3 ± 0.9%) was lower than that in the control group (69.8 ± 0.8%, P = 0.035), and the LV TDI-MPIs for patients with KD at diagnosis (0.49 ± 0.01) and 2 days after IVIG treatment (0.48 ± 0.01) were higher than those in the control group (0.45 ± 0.01, P = 0.002, P = 0.033, respectively). No significant differences were found in the LV dysfunction between the patients with complete and incomplete KD. Septal TDI-MPIs in patients with KD with CAL at diagnosis (0.52 ± 0.02) were higher than those in patients with KD without CAL (0.47 ± 0.01, P = 0.019). CONCLUSIONS Transient LV dysfunction occurred in patients with complete and incomplete KD in the acute stage. In patients with KD with CAL at diagnosis, the LV dysfunction was more prominent. The PD-MPI and TDI-MPI are useful parameters for assessing LV function in patients with KD.

Abstract
BACKGROUND Coarse particulate matter (P10-2.5) is primarily mechanically generated and includes crustal material, brake and tire wear, and biological particles. PM10-2.5 is associated with pulmonary disease, which can lead to right ventricular (RV) dysfunction. Although RV characteristics have been associated with combustion-related pollutants, relationships with PM10-2.5 remain unknown. OBJECTIVES To quantify cross-sectional associations between RV dysfunction and PM10-2.5 mass and components among older adults and susceptible populations. METHODS We used baseline cardiac magnetic resonance images from 1,490 participants (45-84 y old) from the Multi-Ethnic Study of Atherosclerosis and assigned 5-y residential concentrations of PM10-2.5 mass, copper, zinc, phosphorus, silicon, and endotoxin, using land-use regression models. We quantified associations with RV mass, end-diastolic volume, and ejection fraction after control for risk factors and copollutants using linear regression. We further examined personal susceptibility. RESULTS We found positive associations of RV mass and, to a lesser extent, end diastolic volume with PM10-2.5 mass among susceptible populations including smokers and persons with emphysema. After adjustment for copollutants, an interquartile range increase in PM10-2.5 mass (2.2 μg/m3) was associated with 0.5 g (95% CI: 0.0, 1.0), 0.9 g (95% CI: 0.1, 1.7), and 1.4 g (95% CI: 0.4, 2.5) larger RV mass among former smokers, current smokers, and persons with emphysema, respectively. No associations were found with healthy individuals or with ejection fraction. CONCLUSIONS Alterations to RV structure may represent a mechanism by which long-term PM10-2.5 exposure increases risks for adverse respiratory and cardiovascular outcomes, especially among certain susceptible populations. https://doi.org/10.1289/EHP658.

Right Ventricular Remodeling and Dysfunction in Obstructive Sleep Apnea: A Systematic Review of the Literature and Meta-Analysis. Can Respir J 2017; 2017:1587865. [PMID: 28814913 PMCID: PMC5549475 DOI: 10.1155/2017/1587865] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2017] [Accepted: 05/21/2017] [Indexed: 01/01/2023] Open
Abstract
Background Recent studies have reported that obstructive sleep apnea (OSA) patients present alterations in right ventricular (RV) structure and function. However, large randomized controlled trials evaluating the impact of OSA on the right ventricle are lacking. Methods A comprehensive electronic database (PubMed, Web of Science, and Google Scholar) and reference search up to October 30, 2016, was performed. A systematic review and meta-analysis were performed to assess RV structure and function in OSA patients based on conventional echocardiography and tissue Doppler imaging. Results Twenty-five studies with 1,503 OSA patients and 796 controls were included in this study. OSA patients exhibited an increase in RV internal diameter (weighted mean difference (WMD) (95% confidence intervals (CIs)) 2.49 (1.62 to 3.37); p = 0.000) and RV wall thickness (WMD (95% CIs) 0.82 (0.51 to 1.13); p = 0.000). Furthermore, OSA patients had a significantly elevated RV myocardial performance index (WMD (95% CI) 0.08 (0.06 to 0.10); p = 0.000), decreased RV S' (WMD (95% CI) −0.95 (−1.59 to −0.32); p = 0.003), tricuspid annular plane systolic excursion (WMD (95% CI) −1.76 (−2.73 to −0.78); p = 0.000), and RV fractional area change (WMD (95% CI) −3.16 (−5.60 to −0.73); p = 0.011). Conclusion OSA patients display RV dilatation, increased wall thickening, and altered RV function.

Abstract
BACKGROUND It remains unknown whether and to what extent impaired left ventricular ejection fraction (LVEF) affects physical and psychological status in COPD. We aimed to compare health outcome measures between COPD patients with and without impaired LVEF after adjusting for age, sex, BMI and FEV1. METHODS Impaired LVEF was defined as values <50%. 85 COPD patients with impaired LVEF and 85 COPD patients with normal LVEF were matched for sex, age, BMI and FEV1. Exercise capacity, quadriceps muscle function, functional mobility, inflammatory status, health status, care dependency, and mood disorders were cross-sectionally assessed. RESULTS Patients with impaired LVEF had shorter 6-minute walk distance (mean -59 (95% confidence interval: -94, -25)m), lower symptom-limited peak oxygen uptake (-131 (-268, 7)ml/min), weaker quadriceps muscles (-12 (-20, -3)Nm) and had more symptoms of anxiety (+2 (1, 3) points) and depression (+1 (0, 2) points) than those with normal LVEF (all P<0.05). Health status was not statistically different between groups (P>0.05). CONCLUSIONS Impaired LVEF has a clear impact on physical and psychological status in patients with COPD, even after adjusting for confounders. This reinforces the importance of assessing and treating cardiac problems in COPD.

Abstract
Background and objective COPD, a systemic illness associated with the impairment of different organs, affects patient prognosis and quality of life. The aim of this study was to evaluate the association between right ventricle (RV) function, the BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index (a multifunctional scale for the assessment of mortality risk), and quality of life in patients with COPD. Methods A cross-sectional study was carried out in 107 outpatients presenting with stable COPD who underwent clinical assessment, spirometry, arterial blood gas analyses, a 6-minute walk test, electrocardiography, and echocardiogram and who responded to the Saint George’s Respiratory Questionnaire (SGRQ). Results Among the study subjects, 53% (57/107) were males, and the mean age was 65.26±8.81 years. A positive correlation was observed between RV dysfunction measured by the myocardial performance index using tissue Doppler (MPIt) and the BODE index, even after adjustment for age and partial pressure of oxygen (r2=0.47; P<0.01). Patients with alterations in the MPIt had worse quality of life, and a statistically significant difference was found for different domains of the SGRQ. Patients with a normal MPIt had a mean total score of 46.2±18.6, whereas for those with MPIt alterations, the mean total score was 61.6±14.2 (P=0.005). These patients had a 1.49-fold increased risk of exhibiting SGRQ total score above the upper limit of the 95% CI (P=0.01). Conclusion The findings of this study suggest that RV dysfunction as measured by the MPIt was associated with impairment in quality of life and a worse BODE index in COPD patients, irrespective of age and hypoxemia status.

Abstract
BACKGROUND 2D speckle tracking echocardiography (2DSTE) was proved to be accurate for the assessment of the RV function. However, normal values for RV strain refer mostly to 3- or 6-segment models, excluding the contribution of other RV walls to RV function. We analyze RV function by 2DSTE in a normal population, using parasternal two-(2C) and apical four-chamber (4C) RV views, and creating a new 12-segment model for a potential better definition of RV function. METHODS We prospectively evaluated 100 normals using 2DE and STE. We assessed the RV systolic function from regional strain (basal, mid, and apical), and at the level of each wall: lateral (LS), septal (SS), inferior (IS), and anterior (AS), and also global strain for 4C (4CGS), and 2C (2CGS). Global systolic strain rate (SRs) was measured from 2C and 4C views. Diastolic function was assessed from early (SRe) and late global strain rate (SRl), for both views. RESULTS A total of 70 healthy individuals (48±15 years, 34 men) were suitable for concomitant 4C and 2CRV analysis. Feasibility of the STE analysis was 87.8%. We found significantly lower SS by comparison with LS, AS, and IS (P<.001). All S/SR parameters (GS, SRs, and SRe) were higher in 2C view than in 4C view (P<.001). All systolic S/SR parameters did not change with age. The early diastolic SR decreased, while the late diastolic SR increased with age. CONCLUSION Our 12-segment RV strain model is feasible. Moreover, 2DSTE analysis using 2C and 4C views of the RV does not provide similar information. Rather, they offer complementary data. This might be of particularly clinical interest in diseases with regional RV dysfunction.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is characterized by elevated mean pulmonary arterial pressure with abnormal right ventricular (RV) pressure overload that may alter left ventricular (LV) function. The aim of this study was to assess the impact of RV pressure overload on LV function in PAH patients using two-dimensional (2D) speckle tracking strain. METHODS The study enrolled 37 group 1 PAH patients and 38 age- and gender-matched healthy controls. LV longitudinal and radial 2D strains were measured with and without including the ventricular septum. Six-minute walk test (6MWT) and brain natriuretic peptide (BNP) levels were also obtained in patients with PAH. RESULTS The mean age of patients was 46.4 ± 14.8 years, 76% women, and 16 patients (43%) had schistosomiasis. Sixteen patients (43%) were in WHO class III or IV under specific treatment for PAH. The overall 6MWT distance was 441 meters, and the BNP levels were 80 pg/mL. Patients with PAH more commonly presented with LV diastolic dysfunction and impairment of RV function when compared to controls. LV global longitudinal and radial strains were lower in patients than in controls (-17.9 ± 2.8 vs. -20.5 ± 1.9; P < 0.001 and 30.8 ± 10.5 vs. 49.8 ± 15.4; P < 0.001, respectively). After excluding septal values, LV longitudinal and radial strains remained lower in patients than in controls. The independent factors associated with global LV longitudinal strain were LV ejection fraction, RV fractional area change, and tricuspid annular systolic motion. CONCLUSIONS This study showed impaired LV contractility in patients with PAH assessed by speckle tracking strain, irrespective of ventricular septal involvement. Global LV longitudinal strain was associated independently with RV fractional area change and tricuspid annular systolic motion, after adjustment for LV ejection fraction.

Abstract
This study sought to examine the relationships between right ventricular (RV) function and geometry, morbid obesity with and without the metabolic syndrome, and the effect of long-term weight loss. Obese (n = 153, BMI 41.2 ± 8.7 kg/m(2)) and healthy non-obese control subjects (n = 38, BMI 25.5 ± 3.3 kg/m(2)) of similar age and gender distribution were prospectively studied during the course of a 1-year weight reduction program with echocardiography at baseline and after one year of follow up. Function and geometry of the right heart were evaluated by tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (TDI S'), RV myocardial performance index (TEI), RV end-diastolic (RVEDD) and end-systolic diameter (RVESD), area of the right atrium (RAA), and systolic pulmonary artery pressure (PAP). Whereas parameters of systolic and diastolic LV function were significantly worse in the obese subjects than those in the non-obese subjects (EF 66 ± 6 versus 69 ± 6%, P = 0.004; E/E' 7.4 ± 2.5 versus 6.3 ± 2.6, P = 0.010), parameters of RV function (TAPSE 25.6 ± 4.5 versus 25.1 ± 3.5 mm, P = 0.528; TDI S' 13.5 ± 2.9 versus 13.8 ± 2.9 mm/second, P = 0.553; TEI 0.25 ± 0.13 versus 0.28 ± 0.09, P = 0.283) as well as geometry measurements were comparable between the obese and non-obese participants and also in obese subjects with full blown metabolic syndrome. Additionally, successful weight reduction did not alter the RV parameters. Nevertheless, in the few obese subjects with RV dysfunction (n = 7), metabolic syndrome parameters were more pronounced than in obese with normal RV function.Morbid obesity with and without the metabolic syndrome is accompanied by an impaired LV systolic and diastolic function. In contrast, RV function appears to be less affected by obesity independent of the presence of the metabolic syndrome.

Abstract
Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction that results from an inflammatory process affecting the airways and lung parenchyma. Despite major abnormalities taking place in bronchial and alveolar structures, changes in pulmonary vessels also represent an important component of the disease. Alterations in vessel structure are highly prevalent and abnormalities in their function impair gas exchange and may result in pulmonary hypertension (PH), an important complication of the disease associated with reduced survival and worse clinical course. The prevalence of PH is high in COPD, particularly in advanced stages, although it remains of mild to moderate severity in the majority of cases. Endothelial dysfunction, with imbalance between vasodilator/vasoconstrictive mediators, is a key determinant of changes taking place in pulmonary vasculature in COPD. Cigarette smoke products may perturb endothelial cells and play a critical role in initiating vascular changes. The concurrence of inflammation, hypoxia and emphysema further contributes to vascular damage and to the development of PH. The use of drugs that target endothelium-dependent signalling pathways, currently employed in pulmonary arterial hypertension, is discouraged in COPD due to the lack of efficacy observed in randomized clinical trials and because there is compelling evidence indicating that these drugs may worsen pulmonary gas exchange. The subgroup of patients with severe PH should be ideally managed in centres with expertise in both PH and chronic lung diseases because alterations of pulmonary vasculature might resemble those observed in pulmonary arterial hypertension. Because this condition entails poor prognosis, it warrants specialist treatment.

Abstract
Prompt and accurate diagnosis of patients presenting with symptoms suggestive of pulmonary arterial hypertension (PAH) is of outmost importance as delays in identifying this clinical entity have detrimental effects on both morbidity and mortality. Initial noninvasive assessment of these patients has traditionally included a number of routine tests of which transthoracic echocardiography (TTE) has been shown to either confirm the presence of structural anomalies of the right ventricle (RV) indicative of PAH or exclude other potential causes of pulmonary hypertension (PH). Consequently, TTE has become a well-validated and readily available imaging tool not only used for this initial screening but also for routine follow-up of PH patients. Since chronic PH is known to unbalance the normal hemodynamic and mechanical homeostatic interaction between the RV and pulmonary circulation; the resulting response is that of an abnormal RV remodeling, clinically translated into progressive RV hypertrophy and dilatation. An enlarged and hypertrophied RV not only would eventually lose effective contractility but also this gradual decline in RV systolic function is the main abnormality in determining adverse clinical outcomes. Therefore, it is of outmost importance that TTE examination be comprehensive but most importantly accurate and reproducible. This review aims to highlight the most important objective measures that can be routinely employed, without added complexity, that will certainly enhance the interpretation and advance our understanding of the hemodynamic and mechanical abnormalities that PH exerts on the RV.
