The assessment of left ventricular diastolic function: guidance and recommendations from the British Society of Echocardiography. Echo Res Pract 2024; 11:16. [PMID: 38825710 PMCID: PMC11145885 DOI: 10.1186/s44156-024-00051-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 05/13/2024] [Indexed: 06/04/2024] Open
Abstract
Impairment of left ventricular (LV) diastolic function is common amongst those with left heart disease and is associated with significant morbidity. Given that, in simple terms, the ventricle can only eject the volume with which it fills and that approximately one half of hospitalisations for heart failure (HF) are in those with normal/'preserved' left ventricular ejection fraction (HFpEF) (Bianco et al. in JACC Cardiovasc Imaging. 13:258-271, 2020. 10.1016/j.jcmg.2018.12.035), where abnormalities of ventricular filling are the cause of symptoms, it is clear that the assessment of left ventricular diastolic function (LVDF) is crucial for understanding global cardiac function and for identifying the wider effects of disease processes. Invasive methods of measuring LV relaxation and filling pressures are considered the gold-standard for investigating diastolic function. However, the high temporal resolution of trans-thoracic echocardiography (TTE) with widely validated and reproducible measures available at the patient's bedside and without the need for invasive procedures involving ionising radiation have established echocardiography as the primary imaging modality. The comprehensive assessment of LVDF is therefore a fundamental element of the standard TTE (Robinson et al. in Echo Res Pract7:G59-G93, 2020. 10.1530/ERP-20-0026). However, the echocardiographic assessment of diastolic function is complex. In the broadest and most basic terms, ventricular diastole comprises an early filling phase when blood is drawn, by suction, into the ventricle as it rapidly recoils and lengthens following the preceding systolic contraction and shortening. This is followed in late diastole by distension of the compliant LV when atrial contraction actively contributes to ventricular filling. When LVDF is normal, ventricular filling is achieved at low pressure both at rest and during exertion. However, this basic description merely summarises the complex physiology that enables the diastolic process and defines it according to the mechanical method by which the ventricles fill, overlooking the myocardial function, properties of chamber compliance and pressure differentials that determine the capacity for LV filling. Unlike ventricular systolic function where single parameters are utilised to define myocardial performance (LV ejection fraction (LVEF) and Global Longitudinal Strain (GLS)), the assessment of diastolic function relies on the interpretation of multiple myocardial and blood-flow velocity parameters, along with left atrial (LA) size and function, in order to diagnose the presence and degree of impairment. The echocardiographic assessment of diastolic function is therefore multifaceted and complex, requiring an algorithmic approach that incorporates parameters of myocardial relaxation/recoil, chamber compliance and function under variable loading conditions and the intra-cavity pressures under which these processes occur. This guideline outlines a structured approach to the assessment of diastolic function and includes recommendations for the assessment of LV relaxation and filling pressures. Non-routine echocardiographic measures are described alongside guidance for application in specific circumstances. Provocative methods for revealing increased filling pressure on exertion are described and novel and emerging modalities considered. For rapid access to the core recommendations of the diastolic guideline, a quick-reference guide (additional file 1) accompanies the main guideline document. This describes in very brief detail the diastolic investigation in each patient group and includes all algorithms and core reference tables.

Standard volume infusion unmasked diastolic dysfunction in pediatric heart transplant recipients during surveillance cardiac catheterization, but without echocardiographic correlates. Pediatr Transplant 2022; 26:e14323. [PMID: 35642670 DOI: 10.1111/petr.14323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Revised: 04/27/2022] [Accepted: 05/03/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Adult experience evaluating left ventricular diastolic function (LVDFx) includes volume administration during catheterization while obtaining pulmonary capillary wedge pressures (PCWP) or left ventricular end diastolic pressures (LVEDP). Catheterization is inherently challenging in pediatric patients, making echocardiographic assessment ideal. Pediatric echocardiographic studies predicting LVDFx have variable hemodynamic and hydration conditions and have produced inconsistent results. We evaluated the association between simultaneous echocardiographic and catheterization assessment of LVDFx, using a fluid bolus for optimal loading conditions. METHODS Prospective cohort study of pediatric heart transplant recipients receiving echocardiogram simultaneous with routine cardiac catheterization. Mitral valve inflow velocities, septal and lateral wall tissue Doppler indices, and PCWP and/or LVEDP were obtained and repeated following a 10 ml/kg bolus. Echocardiographic parameters were evaluated for an association with changes in PCWP or LVEDP following the bolus. Abnormal LVDFx was defined as PCWP or LVEDP ≥12 mm Hg. RESULTS Twenty-nine patients underwent catheterization. Median pre-bolus PCWP and LVEDP were 11.0 mm Hg and 10.0 mm Hg, respectively. After bolus, median PCWP and LVEDP increased to 14.0 mm Hg (p < .001) and 13 mm Hg (p < .001), respectively. Of 21 patients with normal pre-bolus catheterization hemodynamics, 14 (66.7%) increased to abnormal following fluid bolus. Using area under an ROC, no echocardiographic parameter of LVDFx, or their ratios, were associated with predetermined abnormal LVEDP and/or PCWP. CONCLUSION After bolus, our cohort demonstrated significant increases in LVEDP and/or PCWP, unmasking diastolic dysfunction. Fluid challenges should be considered in pediatric patients undergoing cardiac catheterization with suspected diastolic dysfunction. Echocardiographic measurements were unable to discriminate between normal and abnormal LVEDP and/or PCWP.

Abstract
This study was conducted to investigate the effect of regular endurance exercises on the management of cardiovascular health in middle-aged men. The following conclusions were drawn as the result of comparatively analyzing middle-aged men who regularly performed triathlon and cycling exercises for more than 5 years. The effect of regular endurance exercises on cardiovascular health management in middle-aged men was found to be relatively positive. However, prolonged endurance exercises can cause cardiovascular disease which can adversely affect the cardiac function, and to date, no defining limit is known about the amount of exercise that improves the cardiovascular function while reducing the cardiovascular events. Therefore, aiming for exercises at moderate intensity that befit the individual’s fitness level as well as conducting regular examinations to predict and manage the risk of sudden cardiac death from exercising were considered as the more effective method of cardiovascular health management.

Abstract
Background: Current guidelines on diastolic function (DF) by the American Society of Echocardiography and the European Association of Cardiovascular Imaging (ASE/EACVI) have been disputed and two alternative algorithms have been proposed by Johansen et al. and Oh et al. We sought (a) to assess the concordance of ASE/EACVI guidelines on DF using these proposed alternative approaches and (b) to evaluate the prevalence of indeterminate diastolic dysfunction (DD) by each method, exploring means for reducing their number. Methods: We retrospectively analyzed the echocardiographic reports of 1158 outpatients including subjects at risk of heart failure without (n = 644) or with (n = 241) structural heart disease, and 273 healthy individuals. Concordance was calculated using the k coefficient and overall proportion of DD reclassification rate. The effectiveness of pulmonary vein flow (PVF), Valsalva maneuver, and left atrial volume index/late diastolic a’-ratio (LAVi/a’) over indeterminate grading was assessed. Results: The DD reclassification rate was 30.1% (k = 0.35) for ASE/EACVI and OH, 36.5% (k = 0.27) for ASE/EACVI and JOHANSEN and 31.1% (k = 0.37) for OH and JOHANSEN (p < 0.0001 for all comparisons). DF could not be graded only by ASE/EACVI and OH in 9% and 11% patients, respectively. The majority of patients could be reclassified using PVF or Valsalva maneuver or LAVi/a’, with the latter being the single most effective parameter. Conclusion: Inconsistencies between updated guidelines and independent approaches to assess and grade DF impede their interchangeable clinical use. The inconclusive diagnoses can be reconciled by conventional echocardiography in most patients, and LAVi/a’ emerges as a simple and effective approach to this aim.

Effect of septoplasty on left ventricular myocardial performance in patients with nasal septum deviation. Braz J Otorhinolaryngol 2020; 88:589-593. [PMID: 33067133 PMCID: PMC9422691 DOI: 10.1016/j.bjorl.2020.08.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 07/10/2020] [Accepted: 08/22/2020] [Indexed: 11/23/2022] Open
Abstract
Introduction Nasal septum deviation is the leading cause of upper airway obstruction. Chronic upper airway obstruction may cause myocardial injury due to chronic hypoxia. Effects of septoplasty on left venticular diastolic and sistolic functions are not well known. The myocardial performance index is an easy-to-apply and reliable parameter that reflects systolic and diastolic cardiac functions. Objective The present study aimed to investigate the effect of nasal septoplasty on the myocardial performance index in patients with nasal septal deviation. Methods This prospective study consisted of 50 consecutive patients who underwent septoplasty due to symptomatic prominent C- or S-shaped nasal septal deviation. Transthoracic echocardiogarphy was performed in all patients before and 3 months after septoplasty. Calculated myocardial performance indices were compared. Results Significantly higher left ventricular myocardial performance index (0.52 ± 0.06 vs. 0.41 ± 0.04, p < 0.001), longer isovolumic relaxation time (95.0 ± 12.5 vs. 78.0 ± 8.6 ms, p < 0.001), longer isovolumic contraction time (45.5 ± 7.8 vs. 39.5 ± 8.6 ms, p < 0.001), longer deceleration time (184.3 ± 32.5 vs. 163.6 ± 45.4 ms, p = 0.004), higher ratio of transmitral early to late peak velocities (E/A) (1.42 ± 0.4 vs. 1.16 ± 0.2, p = 0.006) and shorter ejection time (270.1 ± 18.3 vs. 286.5 ± 25.8 ms, p < 0.001) were observed before septoplasty when compared to values obtained 3 months after septoplasty. Left ventricular systolic ejection fraction was similar before and after septoplasty (63.8±2.8% vs. 64.6±3.2%, p = 0.224). Conclusion Septoplasty surgery not only reduces nasal blockage symptoms in nasal septal deviation patients but also may improve left ventricular performance. Thus, treatment of nasal septal deviation without delay is suggested to prevent possible future cardiovascular events.

Abstract
BACKGROUND Left-sided congestive heart failure (CHF) is characterized by increased filling pressures and related Doppler echocardiographic (DE) filling patterns. HYPOTHESIS Doppler echocardiographic variables of left ventricular filling derived from transmitral flow, pulmonary vein flow, and tissue Doppler can be used to detect CHF in cats with hypertrophic cardiomyopathy (HCM). ANIMALS Forty-seven client-owned cats. METHODS Prospective clinical cohort study. Cats underwent physical examination, thoracic radiography, analysis of N-terminal pro-brain natriuretic peptide (NT-proBNP), and transthoracic echocardiography and were divided into 3 age-matched groups: Group 1 (apparently healthy control), Group 2 (preclinical HCM), and Group 3 (HCM and CHF). Measured and calculated variables included respiratory rate, DE estimates, serum NT-proBNP concentration, and radiographic CHF score. Groups were compared using ANOVA, and receiver operating characteristic (ROC) curve and multivariate analyses were used to identify diagnostic cutoffs for the detection of CHF. RESULTS Fifteen cats were in Group 1, 17 in Group 2, and 15 in Group 3. The ROC analysis indicated that the ratio of peak velocity of early diastolic transmitral flow to peak velocity of late diastolic transmitral flow (area under the curve [AUC], 1.0; diagnostic cutoff, 1.77; P = .001), ratio of left atrial size to aortic annular dimension (AUC, 0.91; diagnostic cutoff, 1.96; P = .003), left atrial diameter (AUC, 0.89; cutoff, 18.5 mm; P = .004), diastolic functional class (AUC, 0.89; cutoff, class 2; P = .005), respiratory (AUC, 0.79; cutoff, 36 breaths per minute [brpm]; P = .02), and the ratio of the peak velocity of fused early and late transmitral flow velocities to the peak velocity of the fused early and late diastolic tissue Doppler waveforms (AUC, 0.74; cutoff, 15.1; P = .05) performed best for detecting CHF. CONCLUSIONS AND CLINICAL IMPORTANCE Various DE variables can be used to detect CHF in cats with HCM. Determination of the clinical benefit of such variables in initiating treatments and assessing treatment success needs further study.

Abstract
OBJECTIVE Pneumonia is a leading cause of mortality worldwide, especially in the elderly. The use of clinical risk scores to determine prognosis is complex and therefore leads to errors in clinical practice. Pneumonia can cause increases in the levels of cardiac biomarkers such as N-terminal pro-brain natriuretic peptide (NT-proBNP). The prognostic role of the NT-proBNP level in community acquired pneumonia (CAP) remains unclear. The aim of this study was to evaluate the prognostic role of the NT-proBNP level in patients with CAP, as well as its correlation with clinical risk scores. METHODS Consecutive inpatients with CAP were enrolled in the study. At hospital admission, venous blood samples were collected for the evaluation of NT-proBNP levels. The Pneumonia Severity Index (PSI) and the Confusion, Urea, Respiratory rate, Blood pressure, and age ≥ 65 years (CURB-65) score were calculated. The primary outcome of interest was all-cause mortality within the first 30 days after hospital admission, and a secondary outcome was ICU admission. RESULTS The NT-proBNP level was one of the best predictors of 30-day mortality, with an area under the curve (AUC) of 0.735 (95% CI: 0.642-0.828; p < 0.001), as was the PSI, which had an AUC of 0.739 (95% CI: 0.634-0.843; p < 0.001), whereas the CURB-65 had an AUC of only 0.659 (95% CI: 0.556-0.763; p = 0.006). The NT-proBNP cut-off level found to be the best predictor of ICU admission and 30-day mortality was 1,434.5 pg/mL. CONCLUSIONS The NT-proBNP level appears to be a good predictor of ICU admission and 30-day mortality among inpatients with CAP, with a predictive value for mortality comparable to that of the PSI and better than that of the CURB-65 score.

Abstract
Objectives: To compare soluble-ST2 (sST2) concentrations in patients with severe features of preeclampsia and healthy pregnant controls before as well as 1 year after delivery. Another objective was to assess potential correlation between sST2 concentrations and myocardial function.Methods: Patients with singleton pregnancy complicated by severe features of preeclampsia and healthy controls were included in a prospective observational study. Plasma sST2 concentrations were measured within 24 h before delivery and 1 year after delivery. Standard two-dimensional and Doppler echocardiography was performed at the time of first sST2 measurement before delivery. Mann-Whitney U test was used to compare sST2 values in preeclamptic patients versus controls. Kendall's tau was used to assess correlation between sST2 values and echocardiographic measures of left ventricular systolic and diastolic function (p < .05 significant).Results: We included 24 patients with severe preeclampsia and 29 controls. One year after delivery, sST2 concentrations were available for 24 (45%) participants (13 in preeclampsia group and 11 controls). Concentrations of sST2 were markedly elevated in patients with severe preeclampsia compared to healthy controls before delivery (p = .04), but not 1 year after delivery (p = .80). There was no significant correlation between sST2 and parameters of systolic function. In preeclamptic patients, we found a significant inverse correlation between sST2 and markers of diastolic function: peak early mitral inflow velocity E (Kendall's tau = -0.40; p = .02), peak early diastolic myocardial velocities at septal and lateral mitral annulus (e') (Kendall's tau = -0.354, p = .04) and ratio between e' and peak systolic myocardial velocities at the septal and lateral mitral annulus (e'/s') (Kendall's tau = -0.362, p = .04).Conclusions: Preeclampsia with severe features is associated with increased maternal plasma concentrations of sST2, which return to normal values in the first year after delivery. Higher sST2 levels in preeclamptic patients correlate with impaired parameters of left ventricular diastolic function.

Abstract
Aims The present Euro-Filling report aimed at comparing the diagnostic accuracy of the 2009 and 2016 echocardiographic grading algorithms for predicting invasively measured left ventricular filling pressure (LVFP). Method and results A total of 159 patients who underwent simultaneous evaluation of echo estimates of LVFP and invasive measurements of LV end-diastolic pressure (LVEDP) were enrolled at nine EACVI centres. Thirty-nine (25%) patients had a reduced LV ejection fraction (<50%), 77 (64%) were in NYHA ≥ II, and 85 (53%) had coronary artery disease. Sixty-four (40%) patients had elevated LVEDP (≥15 mmHg). Taken individually, all echocardiographic Doppler estimates of LVFP (E/A, E/e', left atrial volume, tricuspid regurgitation jet velocity) were marginally correlated with LVEDP. By using the 2016 recommendations, 65% of patients with normal non-invasive estimate of LVFP had normal LVEDP, while 79% of those with elevated non-invasive LVFP had elevated invasive LVEDP. By using 2009 recommendations, 68% of the patients with normal non-invasive LVFP had normal LVEDP, while 55% of those with elevated non-invasive LVFP had elevated LVEDP. The 2016 recommendations (sensitivity 75%, specificity 74%, positive predictive value 39%, negative predictive value 93%, AUC 0.78) identified slightly better patients with elevated invasive LVEDP (≥ 15 mmHg) as compared with the 2009 recommendations (sensitivity 43%, specificity 75%, positive predictive value 49%, negative predictive value 71%, AUC 0.68). Conclusion The present Euro-Filling study demonstrates that the new 2016 recommendations for assessing LVFP non-invasively are fairly reliable and clinically useful, as well as superior to the 2009 recommendations in estimating invasive LVEDP.

Abstract
Background Diastolic dysfunction (DD) identified on echocardiography predicts mortality after cardiac surgery, however the most useful diastolic parameters for assessment and the association of DD with prolonged mechanical ventilation, ICU re-admission, and hospital length of stay are not established. Methods We included patients that underwent coronary artery bypass grafting (CABG), aortic valve replacement (AVR) or a combined procedure (CAB-AVR) from 2010 to 2016, and who had preoperative transthoracic echocardiography (TTE) at our institution within 6 months of the operation. Diastolic function was graded using the transmitral E and A waves and the septal tissue Doppler velocity. We performed logistic regression to assess the association of grade of DD with a composite endpoint of death, prolonged mechanical ventilation, ICU readmission during hospitalization, and hospital length of stay longer than 14 days. Results Between 2010 and 2016, 577 patients were eligible for inclusion. DD was common, with 42% of the cohort manifesting grade II or grade III DD. Rates of death and prolonged ventilation increased across grades of DD and across quartiles of increasing LV filling pressure, assessed by the E/e’ ratio. Adjusting for age, sex, procedure, systolic and diastolic function, both systolic (odds ratio 0.68 95% CI 0.55–0.85 per inter-quartile increase in LVEF) and diastolic function (odds ratio 1.31 95% CI 1.04–1.66 per increasing DD grade) both independently predicted outcome. Conclusion Diastolic dysfunction is common among patients undergoing cardiac surgery and is associated with death, prolonged mechanical ventilation, and prolonged hospital and ICU length of stay independent of systolic dysfunction.

Abstract
INTRODUCTION Hiatal hernia (HH) can cause left atrial (LA) compression and impair LA filling. We evaluated the cardiac effects of preload reduction and abdominal strain induced by Valsalva maneuver (VM) in large HH patients. METHODS LA and left ventricular (LV) dimensions were measured using 2D transthoracic echocardiography at rest and during VM in HH patients (n=55, 70±10 years) and controls (n=22, 67±6 years). Biplane LV volumes (n=39) and mitral inflow pulse-wave Doppler parameters (n=27) were also evaluated. In HH patients, resting LA compression was graded qualitatively (none-mild or moderate-severe). RESULTS In both controls and HH patients, VM significantly decreased LA (controls, 19±2 vs 16±3 mm/m2 ; HH, 16±5 vs 9±5 mm/m2 ) and LV diameters (22±3 vs 19±3 mm/m2 ; 21±3 vs 17±3 mm/m2 ) and LV volume (38±8 vs 26±10 mL/m2 ; 31±8 vs 19±9 mL/m2 ) (P<.001 for all). VM decreased LA diameter significantly more in HH patients than controls (-42% vs -16%, P<.001). HH patients with none-mild resting LA compression exhibited significantly greater LA diameter reduction than controls (-38±23% vs -16±13% P=.0003) despite similar resting LA diameters. LV volumes were similarly decreased by VM in HH patients and controls irrespective of resting LA compression severity indicating relative preservation of LV filling. LA diameter correlated inversely with early diastolic filling velocity during VM in HH patients (R=-.43, P=.03) but not controls (R=.18, P=.43). CONCLUSION VM can markedly exacerbate LA compression in HH patients; however, LV filling is relatively less affected possibly due to augmented early diastolic filling. Conditions associated with decreased preload and increased intra-abdominal pressure may exacerbate the cardiac effects of large HH.

Abstract
Left ventricular dysfunction increases left atrial pressures and causes atrial remodeling. In human subjects, increased left atrial size is a powerful predictor of mortality and adverse events in a broad range of cardiac pathologic conditions. Moreover, structural remodeling of the atrium plays an important role in the pathogenesis of atrial tachyarrhythmias. Despite the potential value of the atrium in assessment of functional endpoints in myocardial disease, atrial pathologic alterations in mouse models of left ventricular disease have not been systematically investigated. Our study describes the geometric, morphologic, and structural changes in experimental mouse models of cardiac pressure overload (induced through transverse aortic constriction), myocardial infarction, and diabetes. Morphometric and histological analysis showed that pressure overload was associated with left atrial dilation, increased left atrial mass, loss of myofibrillar content in a subset of atrial cardiomyocytes, atrial cardiomyocyte hypertrophy, and atrial fibrosis. In mice undergoing nonreperfused myocardial infarction protocols, marked left ventricular systolic dysfunction was associated with left atrial enlargement, atrial cardiomyocyte hypertrophy, and atrial fibrosis. Both infarcted animals and pressure overloaded mice exhibited attenuation and perturbed localization of atrial connexin-43 immunoreactivity, suggesting gap junctional remodeling. In the absence of injury, obese diabetic db/db mice had diastolic dysfunction associated with atrial dilation, atrial cardiomyocyte hypertrophy, and mild atrial fibrosis. Considering the challenges in assessment of clinically relevant functional endpoints in mouse models of heart disease, study of atrial geometry and morphology may serve as an important new tool for evaluation of ventricular function.

Abstract
Independently of the lipid-lowering effects, statin has been reported to attenuate the development of diabetic cardiomyopathy. However, the effect of statin in glucose-controlled diabetic condition has not been demonstrated. We evaluated the effect of fluvastatin on cardiac function, fibrosis, and angiotensin-converting enzyme-2 (ACE2) expression in glucose-controlled diabetic rats. Male Wistar rats were randomly divided into four groups: control (Group C), diabetes (Group D), diabetes with insulin (Group I), and diabetes with insulin and fluvastatin (Group I+F). Diabetes was induced by a single injection of streptozotocin (65 mg/kg). After 8 weeks, the hearts were extracted following echocardiographic evaluation. Cardiac fibrosis was analyzed using Masson's trichrome stain. Collagens I and III and ACE2 expressions were evaluated by immunohistochemistry and western blot. Group D showed reduced cardiac systolic function compared to the other groups (all P < 0.05). However, diastolic function estimated by E/A ratio was significantly decreased in groups D and I (median: 0.88 and 1.45, respectively) compared to groups C and I+F (2.97 and 2.15) (all P < 0.05). Cardiac fibrosis was more severe in groups D and I than in groups C and I+F (all P < 0.05) on Masson's trichrome stain. On immunohistochemistry, ACE2 expression was significantly decreased only in group D (all P < 0.05). However, collagen I and III showed higher expressions in group D compared to groups C and I+F while no significant difference was observed compared with group I (all P < 0.05). On western blot, collagen I and ACE2 expressions in group D (median: 1.78 and 0.35, respectively) were significantly different from groups C (references: 1) and I+F (0.76 and 1.21) (all P < 0.05), but not from group I (1.19 and 0.92). Our study suggested a combination of fluvastatin and insulin would be more effective than insulin alone in diabetic hearts. However, the exact mechanism remains to be elucidated.

Abstract
BACKGROUND AND AIMS Prognosis of type 2 diabetes is associated with the occurrence of cardiovascular diseases. Left atrial (LA) size is a predictor of outcome in several diseases, including diabetes. Long duration of diabetes is an established risk factor of poor prognosis. No data are available on the relationship between LA size and duration of diabetes. The present study was aimed to investigate the relationship between LA volume index (LAVI) and the duration of diabetes to test the hypothesis that LA volume will increase as a function of diabetes duration. METHODS AND RESULTS Forty-four male patients with newly diagnosed and 172 male patients with established type 2 diabetes were recruited for this cross-sectional study. All patients were evaluated with a transthoracic echocardiographic Doppler. About 28.2% of patients had increased LAVI. Indices of both diastolic and systolic function were significantly lower in patients with larger left atrium. The values of LAVI increased across classes of duration of diabetes. In multivariable analysis, longer duration was a predictor of LAVI ≥34 ml/m2 (odds ratio 1.65, 95% CI 1.11-2.46, p = 0.014) after adjusting for age, hemoglobin A1c, hypertension, microvascular complication status, and relevant echocardiographic parameters of systolic and diastolic function. CONCLUSIONS These results indicate that duration of diabetes is strongly and positively associated with larger LAVI in type 2 diabetic men with preserved systolic function. Future studies are needed to better elucidate the biological mechanisms underlying linking type 2 diabetes with abnormally increased LAVI in subjects with type 2 diabetes.

Abstract
Left ventricular (LV) diastolic dysfunction is highly prevalent in cats and is a functional hallmark of feline cardiomyopathy. The majority of cats with hypertrophic, restrictive, and dilated cardiomyopathy have echocardiographic evidence of abnormal LV filling, even during the occult (preclinical) phase. Moderate and severe diastolic dysfunction is an indicator of advanced myocardial disease, is associated with clinical signs including exercise intolerance and congestive heart failure, affects outcome, and influences therapeutic decisions. Therefore, identification and quantification of LV diastolic dysfunction are clinically important. Surrogate measures of diastolic function determined by transthoracic two-dimensional, M-mode, and Doppler echocardiographic (DE) methods have been used widely for such purpose. Major functional characteristics of LV diastole, including global function, relaxation and untwist, chamber compliance, filling volume, and the resultant filling pressures can be semi-quantified by echocardiographic methods, and variables retrieved from transmitral flow, pulmonary vein flow, and tissue Doppler recordings are most frequently used. Although there is still a critical lack of well-designed studies in the field, knowledge has steadily accumulated over the past 20 years, reference ranges of diastolic echocardiographic variables have been determined, epidemiological studies have been conducted, and new treatments of diastolic dysfunction in cats have been evaluated. This report will give the reader a summary of the current status in the field of feline diastology with focus on the noninvasive diagnostic methods and interpretation of echocardiographic surrogate measures of LV diastolic function. Lastly, a grading system using a composite of left atrial size and various DE variables potentially useful in the functional classification of LV diastole in cats is introduced.

Abstract
BACKGROUND The power of left atrial (LA) parameters for predicting left ventricular (LV) filling pressure and adverse events in acute heart failure (HF) with severe LV dysfunction, either sinus rhythm or atrial fibrillation (AF), is not fully understood. METHODS AND RESULTS Echocardiography was performed in 141 patients with acute decompensated congestive HF and LV ejection fraction <35%, including 42 with permanent AF. The LA expansion index was calculated as (Volmax - Volmin) × 100%/Volmin, where Volmax was defined as maximal and Volmin as minimal LA volume. Of 141 patients, invasive LV filling pressures within 12 hours of LA expansion index measurement were available in 109. The end points were 3-year frequencies of HF hospitalization and all-cause mortality. Over a median follow-up of 3.1 years, 74 participants (52.5%) reached the end points (sinus vs AF group: 48.5% vs 61.9%, respectively; P = .047). Multivariate analysis revealed that adverse events of both groups were only independently associated with age and LA expansion index. Rates of adverse events were proportional to LA expansion index. There was a good logarithmic relationship between LA expansion index and LV filling pressure, regardless of presence or absence of AF. CONCLUSIONS LV filling pressure can be estimated well by LA expansion index, with or without AF. The LA expansion index predicts adverse events in HF patients with severe systolic dysfunction.

Abstract
The presence of left ventricular (LV) diastolic dysfunction (DD) as characterized by Doppler echocardiography is associated with worse overall mortality both in symptomatic and asymptomatic patients. However, available data on this topic come from referral centers and have been obtained by different, validated algorithms for each single study. Thus, we aimed at determining the feasibility of comprehensive evaluation of LVDD in a primary care outpatient setting and at testing the concordance of different methodological approaches in grading diastolic dysfunction. Eight hundred eighty-five consecutive outpatients, in sinus rhythm, prospectively underwent Doppler echocardiography according to a predetermined protocol. Feasibility of each LV diastolic index and concordance between 3 methods to determine the degree of LVDD, namely the American Society of Echocardiography/European Association of Echocardiography (ASE/EAE) recommendations, the Olmstead County, and the Canberra Study protocols, were tested. Feasibility of all diastolic indexes was high, ranging from 93% of Valsalva maneuver to ≥99% for mitral inflow and tissue Doppler parameters. Diastolic function was not classifiable in 6% to 19% of patients. The concordance for LV diastolic dysfunction degree was fair when comparing the classification of the ASE/EAE with those from Olmstead County (κ = 0.25; reclassification rate 51%) and Canberra Study (κ = 0.27; reclassification rate 43.7%), and was good for the comparison between the Olmstead County and Canberra classifications (κ = 0.68, reclassification rate 27%). In conclusion, feasibility of LV diastolic function measurements is very high and grading diastolic dysfunction is possible in most patients in primary care settings. Substantial differences, however, exist when concordance is tested among 3 documented criteria, resulting in poor concordance of data interpretation and hence patient stratification and clinical management.

"Left ventricular filling pressure(s)" - Ambiguous and misleading terminology, best abandoned. Int J Cardiol 2015; 191:110-3. [PMID: 25965616 DOI: 10.1016/j.ijcard.2015.04.254] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2015] [Accepted: 04/30/2015] [Indexed: 11/23/2022]
Abstract
The use of the terms "left ventricular filling pressure" and "left ventricular filling pressures" is widespread in the cardiology literature, but the meanings ascribed to these terms have not been consistent. Left ventricular end-diastolic pressure (LVEDP) and mean left atrial pressure (LAP) cannot be used interchangeably as they will often differ in magnitude in the presence of cardiac disease and they also have different clinical significance. LVEDP is the best pressure to use when considering left ventricular function, whereas mean LAP is the most relevant pressure when considering the tendency to pulmonary congestion. The mean LAP is also the most relevant pressure for determining whether pulmonary hypertension has a left heart (post-capillary) component. If only a left ventricular pressure tracing is available then a technique to measure the mean left ventricular diastolic pressure is the best option for estimating the mean LAP. If only right heart pressures are available then the pulmonary artery end-diastolic pressure will provide a reasonable estimate of LVEDP, but only when the heart and pulmonary circulation are normal. If there is mitral valve disease, left ventricular disease or pulmonary hypertension the LVEDP cannot be estimated from right heart pressures. The problem of the ambiguity of "filling pressure (s)" is readily solved by the abandonment of this term and the use of either LVEDP or mean LAP as appropriate.

Abstract
BACKGROUND Left ventricular (LV) diastolic dysfunction is associated with new-onset atrial fibrillation (AF), and the estimation of elevated LV filling pressures by E/e' ratio is related to worse outcomes in patients with AF. However, it is unknown if restoring sinus rhythm reverses this process. OBJECTIVE To evaluate the impact of AF ablation on estimated LV filling pressure. METHODS A total of 141 patients underwent radiofrequency (RF) ablation to treat drug-refractory AF. Transthoracic echocardiography was performed 30 days before and 12 months after ablation. LV functional parameters, left atrial volume index (LAVind), and transmitral pulsed and mitral annulus tissue Doppler (e' and E/e') were assessed. Paroxysmal AF was present in 18 patients, persistent AF was present in 102 patients, and long-standing persistent AF in 21 patients. Follow-up included electrocardiographic examination and 24-h Holter monitoring at 3, 6, and 12 months after ablation. RESULTS One hundred seventeen patients (82.9%) were free of AF during the follow-up (average, 18 ± 5 months). LAVind reduced in the successful group (30.2 mL/m(2) ± 10.6 mL/m(2) to 22.6 mL/m(2) ± 1.1 mL/m(2), p < 0.001) compared to the non-successful group (37.7 mL/m(2) ± 14.3 mL/m(2) to 37.5 mL/m(2) ± 14.5 mL/m(2), p = ns). Improvement of LV filling pressure assessed by a reduction in the E/e' ratio was observed only after successful ablation (11.5 ± 4.5 vs. 7.1 ± 3.7, p < 0.001) but not in patients with recurrent AF (12.7 ± 4.4 vs. 12 ± 3.3, p = ns). The success rate was lower in the long-standing persistent AF patient group (57% vs. 87%, p = 0.001). CONCLUSION Successful AF ablation is associated with LA reverse remodeling and an improvement in LV filling pressure.

Abstract
Background According to some international studies, patients with acute coronary syndrome
(ACS) and increased left atrial volume index (LAVI) have worse long-term
prognosis. However, national Brazilian studies confirming this prediction are
still lacking. Objective To evaluate LAVI as a predictor of major cardiovascular events (MCE) in patients
with ACS during a 365-day follow-up. Methods Prospective cohort of 171 patients diagnosed with ACS whose LAVI was calculated
within 48 hours after hospital admission. According to LAVI, two groups were
categorized: normal LAVI (≤ 32 mL/m2) and increased LAVI (> 32
mL/m2). Both groups were compared regarding clinical and
echocardiographic characteristics, in- and out-of-hospital outcomes, and
occurrence of ECM in up to 365 days. Results Increased LAVI was observed in 78 patients (45%), and was associated with older
age, higher body mass index, hypertension, history of myocardial infarction and
previous angioplasty, and lower creatinine clearance and ejection fraction. During
hospitalization, acute pulmonary edema was more frequent in patients with
increased LAVI (14.1% vs. 4.3%, p = 0.024). After discharge, the occurrence of
combined outcome for MCE was higher (p = 0.001) in the group with increased LAVI
(26%) as compared to the normal LAVI group (7%) [RR (95% CI) = 3.46
(1.54-7.73) vs. 0.80 (0.69-0.92)]. After Cox regression, increased LAVI
increased the probability of MCE (HR = 3.08, 95% CI = 1.28-7.40, p = 0.012). Conclusion Increased LAVI is an important predictor of MCE in a one-year follow-up.

Abstract
OBJECTIVES To identify differences in cardiac hemodynamic changes between the Valsalva maneuver and nitroglycerin (NTG) administration. METHODS Fifty-three subjects (37 men, 43 ± 12 years) with normal cardiac function [left ventricular ejection fraction ≥55%, early to late mitral inflow velocity ratio (E/A) ≥1, left atrial volume index ≤34 ml/m(2) and early diastolic mitral annulus velocity (E') ≥8 cm/s] were enrolled. Doppler parameters were determined at rest, during the Valsalva maneuver and after NTG administration. RESULTS Decreased E, A and E/A were observed both during the Valsalva maneuver and after NTG administration (p < 0.0001 for all). However, the reduction in E (ΔEValsalva: -30 ± 16 cm/s vs. ΔENTG: -17 ± 17 cm/s) and E/A (ΔE/AValsalva: -0.37 ± 0.28 vs. ΔE/ANTG: -0.19 ± 0.25) and the prolongation of the deceleration time (DT) of E (ΔDTValsalva: 105 ± 74 ms vs. ΔDTNTG: 83 ± 63 ms) were more prominent during the Valsalva maneuver than with NTG administration (p < 0.0001 for all). Particularly, a greater decrease in E' was observed during the Valsalva maneuver (ΔE'Valsalva: -3 ± 2 cm/s vs. ΔE'NTG: -2 ± 2 cm/s, p < 0.0001). Eighteen subjects (34%) showed ΔE/A ≥0.5 during the Valsalva maneuver; thus, they were mislabeled as 'pseudonormal', while only 3 subjects (6%) showed ΔE/A ≥0.5 after NTG administration. CONCLUSIONS The Valsalva maneuver not only decreases preload but also affects myocardial performance, thus, its use can result in the mislabeling of normal subjects as pseudonormal.

Tissue doppler myocardial performance index in patients with heart failure and its relationship with haemodynamic parameters. Int J Cardiovasc Imaging 2014; 30:1057-64.

Abstract
The myocardial performance index (MPI) reflects both the systolic and diastolic function of the heart, and is easily applied in practice. In this study, we aimed to determine the relationship between MPI and invasive haemodynamic parameters in heart failure patients. A total of 126 patients with heart failure were selected, all of whom were referred for diagnostic cardiac catheterisation, and were divided into two groups. Group I consisted of 59 patients (32 men and 27 women, mean age 61 ± 10; functional capacity New York Heart Association (NYHA) Class I; and left ventricular end-diastolic pressure (LVEDP) <16 mmHg). Group II included 67 patients (34 men and 33 women, mean age 60 ± 9; NYHA Class ≥ II; LVEDP ≥ 16 mmHg). The following parameters were measured in all patients: ejection fraction with Simpson method, the peak mitral early (E) and late (A) diastolic velocities, E/A ratio, deceleration time (DT) and tissue Doppler from four different areas of the mitral annulus (septum, lateral, inferior and anterior). In order to measure MPI with two methods (standard Doppler and tissue Doppler), isovolumetric contraction time (IVCT), isovolumetric relaxation time (IVRT) and ejection time (ET) were measured from four areas and mean values of MPI were calculated. There was no difference between the two groups in E/A ratios, DT and IVRT (p > 0.05). Group II patients had longer IVCT and ET, when compared with group I patients (p < 0.05). MPI, measured by both standard pulsed wave Doppler and tissue Doppler methods, was significantly higher in group II patients, when compared with the values obtained from group I patients (Group I: 0.50 ± 0.2 and 0.50 ± 0.14; group II: 0.98 ± 0.3 and 1.2 ± 0.32; p < 0.001). According to receiver operating characteristics curve analysis, the cut-off value for MPI measured by tissue Doppler was 0.74. The sensitivity and specificity of this value were measured as 92.5 and 91.5%, respectively. MPI measured by standard Doppler method was 0.67, and its sensitivity and specificity were 85.1 and 83.1%, respectively. We found a strong relationship between MPI and LVEDP (r = 0.83, p < 0.001; r = 0.96, p < 0.001), especially when measured by tissue Doppler. In addition, we observed a significant relationship between the MPI values measured by tissue Doppler and those measured by standard traditional methods (r = 0.85, p < 0.001). We showed that MPI was reliable for the evaluation of global cardiac functions in patients with heart failure, as measured with both pulsed-wave Doppler and tissue Doppler. We assert that, in order to differentiate between those patients with symptomatic heart failure from the asymptomatic cases, MPI as measured with the tissue Doppler method is an improvement on MPI as measured using traditional methods.

Abstract
OBJECTIVES The study sought to determine the prognostic importance of left atrial (LA) dilation in patients with type 2 diabetes mellitus (T2DM) and no history of cardiovascular disease (CVD). BACKGROUND T2DM is associated with the development of CVD, and morphological changes in the heart may appear before symptoms arise. METHODS A total of 305 T2DM patients without known CVD referred to a diabetes clinic were included consecutively (age 58.6 ± 11.3 years, diabetes duration 2.0 [interquartile range: 0 to 6.0] years). Each patient underwent a comprehensive echocardiogram and a myocardial perfusion scintigraphy (MPS) at inclusion. Patients were divided according to left atrial volume index (LAVi) ≥32 ml/m(2). Patients were followed for median of 5.6 (interquartile range: 5.1 to 6.1) years for the occurrence of major cardiac events and death. RESULTS LAVi ≥32 ml/m(2) was found in 105 patients (34%). During follow-up, 60 patients (20%) experienced the composite endpoint, of whom 28 (9%) died. Patients with LAVi ≥32 ml/m(2) had a significantly higher cardiac event rate and death rate (p < 0.001 and p = 0.002, respectively). Univariate predictors of the composite endpoint were age, hypertension, left ventricular diastolic function, E/e'septum-ratio and LAVi ≥32 ml/m(2); however, myocardial ischemia on MPS was not a predictor. When adjusting for age and hypertension, only LAVi ≥32 ml/m(2) was a predictor of the composite endpoint (hazard ratio: 1.82 [95% confidence interval: 1.08 to 3.07], p = 0.024). CONCLUSIONS Increased LAVi was an independent and incremental predictor of cardiovascular morbidity and mortality in T2DM patients with no history of CVD.

Clin Res Cardiol 2013; 102:563-70.

Abstract
OBJECTIVES The value of conventional non-invasive Doppler parameters to predict ventricular end-diastolic pressure (EDP) and diastolic function in congenital heart diseases is limited. The aim of our prospective study was to investigate whether the ratio of mitral early blood inflow velocity to early diastolic velocity of the mitral annulus (E/e') as assessed by pulsed tissue Doppler is related to EDP in patients with different congenital heart disease (CHD) undergoing left heart catheterization. METHODS A total of 115 hospital inpatients (64 male) with different CHD referred for cardiac catheterization were simultaneously examined by echocardiography for non-invasive estimation of ventricular EDP during heart catheterization. The mean age at catheterization was 8.71 years (range 3 days to 18 years). These patients were divided into two groups according to the different hemodynamic and morphology conditions: group A consisted of patients with biventricular heart and group B of patients with univentricular heart. RESULTS For all the studied patients, a significant positive correlation was found between E/e' and EDP (r = 0.54, P < 0.001). EDP correlated rather weakly with combined measurements E/global LV early diastolic velocity (r = 0.27, P = 0.02). A significant relationship was also found between ventricular EDP and early mitral inflow velocity E (r = 0.36, P = 0.001). The ratio of pulmonary venous flow velocities s/d was not found to be related to invasively measured EDP (r = -0.16, P = 0.13). Group A (n = 96) had similar results, but for group B (n = 19), these parameters did not show a relationship to EDP. The analysis of these parameters showed that the larger area under the curve (AUC) was found for the ratio of E/e' (AUC = 0.77) compared with E/global e' (AUC = 0.57). E/e' > 10.7 had 69 % sensitivity and 81 % specificity for EDP > 10 mmHg. CONCLUSION Doppler and tissue Doppler-derived E/e' ratio is related to simultaneous invasive measurement of EDP in a heterogeneous group of patients with CHD and may provide an additional surrogate non-invasive estimation of ventricular diastolic performance in the routine follow-up of these patients.

Abstract
Purpose Interatrial block (IAB) frequently coexists with sinus node disease and is considered a risk factor of left atrial dysfunction, atrial arrhythmias, and heart failure development. Conventional right atrial appendage (RAA) pacing impairs intra- and interatrial conductions and consequently prolongs P wave duration. Biatrial (BiA) pacing helps correct IAB, but its advantageous influence remains controversial. The aim of the study was to compare the effects of BiA and RAA pacing on cardiac hemodynamics and serum concentrations of inflammatory markers and neuropeptides. Methods Twenty-eight patients with IAB and preserved atrio-ventricular conduction treated with BiA pacing were studied. Standard invasive hemodynamic measurements were performed during BiA and RAA pacings. Furthermore, the influence of 1 week of BiA and RAA pacing on neuropeptides: atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) and markers of inflammation: high sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), and neopterin was examined. Results BiA pacing resulted in significant increase of cardiac output (CO) and reduction of pulmonary capillary wedge pressure. We demonstrated significantly lower concentrations of ANP, hs-CRP, IL-6, and neopterin after 1 week of BiA in comparison to RAA pacing. BNP levels remained unchanged. Conclusions BiA pacing in comparison to RAA pacing improves hemodynamic performance in patients with IAB and preserved atrio-ventricular conduction. BiA pacing is associated with reduction of ANP and markers of inflammation (hs-CRP, IL-6, and neopterin).

Abstract
OBJECTIVE This study evaluated the prognostic value of the aortic calcification index (ACI), an estimate of abdominal aortic calcification by plain abdominal computed tomography (CT), in terms of left ventricular (LV) diastolic dysfunction, mortality, and nonfatal cardiovascular (CV) events in peritoneal dialysis (PD) patients. METHOD PD patients who received both abdominal CT and echocardiography were divided into a low-ACI group (n=46) and a high-ACI group (n=46). RESULTS During follow-up (median, 35.2 months; range, 3.6-111.3), 30 patients (32.6%) died and 10 patients (10.9%) developed nonfatal cardiovascular (CV) events. The 5-year event-free survival rates for mortality and nonfatal CV events were significantly lower in the high-ACI group compared with those in the low-ACI group (35.7% vs. 64.1%, P = 0.01). The ACI was positively correlated with left atrial diameter and ratio of peak early transmitral flow velocity to peak early diastolic mitral annular velocity (E/E' ratio; a marker of left ventricular diastolic function). Using multivariate analyses, the high-ACI group (vs. low-ACI group, HR 5.25, 95% CI 1.77-15.58, P = 0.003) and increased E/E' ratio (HR 1.16, 95% CI 1.03-1.31, P = 0.013) were independent predictors for mortality and CV events. The ACI provided a higher predictive value for adverse outcomes (AUC = 0.755, P = 0.002) than the E/E' ratio (AUC = 0.543, P = 0.61). CONCLUSION The ACI was significantly associated with left ventricular diastolic dysfunction and predicted all-cause mortality and nonfatal CV events in PD patients.

Abstract
Mitral regurgitation (MR) of even mild severity affects the prognosis of patients with acute coronary syndrome (ACS). The present study retrospectively analyzed 1,142 patients with ACS and MR of varying severity. Of the 95 patients with severe MR, 57 (60%) underwent primary percutaneous coronary intervention only and 38 (40%) underwent coronary artery bypass grafting (CABG) and mitral valve replacement (MVR). The severity of MR was significantly associated with the risk of heart failure but not with in-hospital or long-term mortality. In patients with severe MR, in-hospital mortality was no greater in those treated with CABG and MVR than in those treated with percutaneous coronary intervention alone. However, the incidence of long-term hard events (heart failure and all-cause mortality) was lower in those who had received the combined treatment. Multivariate analysis showed that, compared to percutaneous coronary intervention alone, CABG combined with MVR at the acute phase of ACS resulted in a significantly improved prognosis (odds ratio 0.172, 95% confidence interval 0.046 to 0.649, p = 0.009), even after adjusting for age, left ventricular filling pressure, and ejection fraction. In conclusion, the severity of MR in patients with ACS is associated with long-term heart failure events. Even at the acute phase of ACS, CABG combined with MVR results in an acceptable in-hospital mortality rate. The combined strategy also reduced the long-term hard events.

Abstract
PURPOSE OF REVIEW Nearly half of patients presenting with heart failure have a preserved left ventricular ejection fraction (LVEF), previously known as diastolic heart failure. The diagnosis requires fulfillment of three criteria: signs or symptoms of heart failure, presence of a normal LVEF, and evidence of diastolic dysfunction. Two of the criteria can be evaluated by echocardiography. This article reviews the echocardiographic approach to the patient with suspected heart failure with a normal left ventricular ejection fraction (HFNEF). RECENT FINDINGS Echocardiography is the primary modality for evaluating left ventricular (LV) systolic and diastolic function in heart failure patients. Measurements of LVEF from two-dimensional echocardiography can have significant variability despite the use of quantitative methods. The use of contrast agents and three-dimensional echocardiography can improve the accuracy. Newer modalities of tissue Doppler imaging and deformation imaging are challenging the concept that systolic function is preserved in HFNEF. Evaluation of diastolic function with echocardiography requires a comprehensive approach using multiple modalities to quantitate transmitral flow, pulmonary venous flow, mitral annular motion, myocardial deformation, and cardiac structure. The clinical applicability of parameters used for evaluating diastolic function and filling pressures is dependent on the LVEF, necessitating a unique approach in patients with suspected HFNEF. SUMMARY A comprehensive examination with knowledge of the potential limitations of echocardiography is required to accurately interpret LV systolic and diastolic function in patients with suspected HFNEF.

Abstract
The purpose of this study is to assess the relationship between left atrial (LA) size and outcome after acute myocardial infarction (AMI) in patients undergoing primary percutaneous coronary intervention (PCI) and to evaluate dynamic changes in LA size during long-term follow-up. Echocardiographic analyses were performed on 253 AMI patients (174 male and 79 female, 65.4 ± 13.7 yr) undergoing PCI. These subjects were studied at baseline and at 12 months. Clinical follow-up were done at 30.8 ± 7.5 months. We assessed LA volume index (LAVI) at AMI-onset and at 12-month. Change of LAVI was an independent predictor of new onset of atrial fibrillation or hospitalization for heart failure (P = 0.002). Subjects who survived the 12-month period displayed an increased LAVI mean of 1.86 ± 4.01 mL/m(2) (from 26.1 ± 8.6 to 28.0 ± 10.1 mL/m(2), P < 0.001). The subject group that displayed an increased LAVI correlated with a low left ventricular ejection fraction, large left ventricle systolic and diastolic dimensions and an enlarged LA size. In conclusion, change of LAVI is useful parameter to predict subsequent adverse cardiac event in AMI patients. Post-AMI echocardiographic evaluation of LAVI provides important prognostic information that is significantly greater than that obtained from clinical and laboratory parameters alone.

Abstract
Because of diastolic coupling between the left atrium and left ventricle, we hypothesized that left atrial (LA) function mirrors the diastolic function of left ventricle. The aims of this study were to assess whether LA volume parameters can be good indexes of left ventricular diastolic dysfunction. Six hundred fifty-nine patients underwent cardiac catheterization and measurements of left ventricular filling pressure (LVFP). Echocardiographic examinations including tissue Doppler and LA volumes were also assessed. Ratio of early diastolic mitral inflow velocity to early diastolic mitral annular velocity and LVFP tended to increase after progression of diastolic dysfunction. The inverse phenomenon existed in LA ejection and LA distensibility. LA distensibility was superior to LA ejection fraction and early diastolic mitral inflow velocity/early diastolic mitral annular velocity for identifying LVFP >15 mm Hg (areas under receiver operating characteristic curve 0.868, 0.834, and 0.759, respectively) and for differentiating pseudonormal from normal diastolic filling (areas under receiver operating characteristic curve 0.962, 0.907, and 0.741, respectively). Multivariate logistic regression showed that LA ejection fraction and LA distensibility were associated significantly with the presence of pseudonormal/restrictive ventricular filling. In conclusion, LA volume parameters can identify LVFP >15 mm Hg and differentiate among patterns of ventricular diastolic dysfunction. For assessing diastolic function LA parameters offer better performance than even tissue Doppler.

Abstract
Background: the transition to microgravity eliminates the hydrostatic gradients in the vascular system. The resulting fluid redistribution commonly manifests as facial edema, engorgement of the external neck veins, nasal congestion, and headache. This experiment examined the responses to modified Valsalva and Mueller maneuvers measured by cardiac and vascular ultrasound (ECHO) in a baseline steady state and under the influence of thigh occlusion cuffs available as a countermeasure device (Braslet cuffs). Methods: nine International Space Station crewmember subjects (expeditions 16–20) were examined in 15 experiment sessions 101 ± 46 days after launch (mean ± SD; 33–185). Twenty-seven cardiac and vascular parameters were obtained with/without respiratory maneuvers before and after tightening of the Braslet cuffs (162 parameter states/session). Quality of cardiac and vascular ultrasound examinations was assured through remote monitoring and guidance by investigators from the NASA Telescience Center in Houston, TX, and the Mission Control Center in Korolyov, Moscow region, Russia. Results: 14 of 81 conditions (27 parameters measured at baseline, Valsalva, and Mueller maneuver) were significantly different when the Braslet was applied. Seven of 27 parameters were found to respond differently to respiratory maneuvers depending on the presence or absence of thigh compression. Conclusions: acute application of Braslet occlusion cuffs causes lower extremity fluid sequestration and exerts commensurate measurable effects on cardiac performance in microgravity. Ultrasound techniques to measure the hemodynamic effects of thigh cuffs in combination with respiratory maneuvers may serve as an effective tool in determining the volume status of a cardiac or hemodynamically compromised patient at the “microgravity bedside.”

Abstract
BACKGROUND Atrial fibrillation (AF), a common complication after coronary artery bypass graft surgery (CABG), is associated with prolonged hospital stay. This prospective study assessed the accuracy of left atrial parameters and additional preoperative characteristics for predicting post-CABG AF and in-hospital mortality. METHODS A total of 197 patients without hemodynamic-significant valvular problems, who received isolated CABG, were enrolled. Echocardiography was performed before CABG. RESULTS Compared with patients without post-CABG AF, those with post-CABG AF were older (71 vs 64 years, p<0.0001), had a higher incidence of CABG during index hospitalization of acute myocardial infarction and preoperative respiratory failure requiring ventilator support, lower left ventricular ejection fraction (0.41 vs 0.48, p<0.0001), lower left atrial expansion index (52.2% vs 93.3%, p<0.0001), and higher left ventricular filling pressure (24.2 vs 19.1 mm Hg, p<0.0001). Multivariate analysis of preoperative variables showed that independent predictors of AF included age (odds ratio [OR], 1.064; 95% confidence interval [CI], 1.022 to 1.107 per 1-year increase; p 0.002), maximal indexed left atrial volume (OR, 1.026; 95% CI, 1.002 to 1.051 per 1 mL/m2 increase; p 0.037) and left atrial expansion index (OR, 0.981; 95% CI, 0.962 to 0.998 per 1% increase; p 0.029). The left atrial expansion index was also significantly associated with in-hospital mortality (OR, 0.982; 95% CI, 0.951 to 0.996 per 1% increase; p 0.042). Incidence of post-CABG AF in patients with left atrial expansion index less than 120% progressively increased as left atrial expansion index decreased. CONCLUSIONS Left atrial expansion index independently predicts post-CABG AF and in-hospital mortality.

Abstract
OBJECTIVES Our goal was to investigate whether left ventricular (LV) diastolic dysfunction was an important pathophysiological mechanism underlying the initiation of new-onset post-operative atrial fibrillation (POAF). BACKGROUND Atrial fibrillation is a common complication after cardiac surgery. However, the precise mechanism underlying its development remains poorly understood. Pre-existing alterations of myocardial diastolic function may predispose patients to the development of POAF. METHODS Patients were residents of Olmsted County, Minnesota, who underwent complete LV diastolic function assessment before coronary artery bypass grafting and/or valve surgery between January 1, 2000, and December 31, 2005. All were in sinus rhythm and had no history of atrial fibrillation, a pacemaker, mitral stenosis, or congenital heart disease. POAF was defined as any episode of atrial fibrillation within 30 days after surgery. RESULTS POAF occurred in 135 of 351 patients (38.5%). Patients with POAF were older (mean age 72.5 ± 10.3 years vs. 63.1 ± 14.1 years; p < 0.001) and more likely to have abnormal diastolic function. The rate of POAF increased exponentially with diastolic function grade (DFG) severity (p < 0.001). By multivariate analysis, after adjusting for clinical and surgical risk factors, independent predictors of POAF were older age (odds ratio [OR]: 1.05; p < 0.001), higher body mass index (OR: 1.06; p = 0.03), and abnormal LV DFG (DFG 1, OR: 5.12 [p = 0.006]; DFG 2, OR: 9.87 [p < 0.001]; and DFG 3, OR: 28.52 [p < 0.001]). CONCLUSIONS LV diastolic dysfunction is a powerful, independent predisposing substrate for the initiation of POAF. Evaluation may be useful during risk stratification of patients undergoing cardiac surgery.
