Left ventricular structural abnormalities in the assessment of diastolic function in the elderly: source of discrepancies between the 2009 and 2016 criteria.

Diastolic dysfunction (DD) is routinely evaluated in echocardiography to support diagnosis, prognostication, and management of heart failure, a condition highly prevalent in elderly patients. Clinical guidelines were published in 2009, and updated in 2016, pursuing to standardize and improve DD categorization. We aimed to assess the concordance of DD between these two documents in an elderly population and to investigate how left ventricular structural abnormalities (LVSA) impact the reclassification. To evaluate this we analyzed the 308 consecutive transthoracic echocardiograms in patients older than 60 years (70.4 ± 7.7 years-old, 59% women) that fulfilled the inclusion criteria out of the 1438 echocardiograms performed in a tertiary hospital. We found that the prevalence of DD was lower according to the 2016 criteria (64% vs. 91%; p < 0.001), with 207 (67.2%) patients changing category, indicating poor agreement between the guidelines (kappa = 0.21). There were 188 (61%) patients with LVSA, which drove most of the reclassifications in 2016 Grade I DD cases. The prevalence of elevated filling pressures by Doppler halved in this elderly population using the updated recommendations (20.9% vs. 39.2%; p < 0.001). In conclusion the prevalence of DD was lower applying the 2016 guidelines, with a poor agreement with 2009 guidelines in all DD grades. The role of LVSA in reclassifications was particularly evident in Grade I DD, while Doppler parameters drove reclassifications among the more severe grades. If not properly addressed, these discrepancies may undermine the reliance on DD as a diagnostic and prognostic tool, particularly in an elderly population at a higher risk of heart failure.

Monocyte-to-lymphocyte ratio as predictor of cancer therapy-related cardiotoxicity in patients with breast cancer: a pilot cohort study.

BACKGROUND: Elevated pre-treatment baseline inflammation has been associated with cancer therapy-related cardiac dysfunction (CTRCD) in patients with breast cancer. Monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio and systemic immune-inflammation index (NLR × platelets) have emerged in clinical context as markers of disease-related inflammation. OBJECTIVES: To evaluate development of CTRCD according to pre-treatment blood inflammatory biomarkers in patients with breast cancer. METHODS: Pilot cohort study including consecutive female patients ≥ 18 years with HER2-positive early breast cancer who consulted at the institution's breast oncology outpatient clinic between march/2019 and march/2022. CTRCD: absolute reduction in LVEF > 10% to below 53% (2D-echocardiogram). Survival analysis was performed using Kaplan-Meier curves, compared by the log-rank test, and discrimination ability was evaluated through AUC-ROC. RESULTS: Forty-nine patients (53.3 ± 13.3 y) were included and followed-up for a median of 13.2 months. CTRCD was observed in 6 (12.2%) patients. Patients with high blood inflammatory biomarkers had lower CTRCD-free survival (P < 0.050 for all). MLR showed statistically significant AUC (0.802; P = 0.017). CTRCD was observed in 27.8% of patients with high MLR versus 3.2% with low MLR (P = 0.020); negative predictive value was 96.8% (95%CI 83.3-99.4%). CONCLUSION: In patients with breast cancer, elevated pre-treatment inflammatory markers were associated with increased risk of cardiotoxicity. Among these markers, MLR had good discriminatory performance and high negative predictive value. The incorporation of MLR might improve risk evaluation and selection of patients for follow-up during cancer therapy.

Prognostic value of right ventricular strain and peak oxygen consumption in heart failure with reduced ejection fraction.

Our purpose is to evaluate the combined predictive value of cardiopulmonary exercise testing (CPET) and echocardiographic evidence of left ventricular (LV) and right ventricular (RV) strain in predicting mortality and heart transplant (HTx) in a series of outpatients with heart failure with reduced ejection fraction (HFrEF). A retrospective cohort study of 66 patients with HFrEF (median age, 57 years; 51% women) who underwent CPET and echocardiography (up to 90 days apart) to assess prognosis. The primary outcome was a composite of death and need for HTx. At a median follow-up of 27 [20-39] months, 19 patients (29%) experienced the primary outcome. In unadjusted analysis, most echocardiographic and CPET parameters were associated with the primary outcome, including percentage of predicted peak oxygen consumption (ppVO2), VE/VCO2 slope, LV ejection fraction, and LV and RV longitudinal strain. After adjusting for other clinical, echocardiographic and CPET variables, RV free wall longitudinal strain and ppVO2 remained significantly associated with the primary outcome. Kaplan-Meier survival curves for death and HTx, based on the best cutoff values, showed lower survival rates in patients with impairment in both ppVO2 and RV FW-LS than in those with one or neither parameter impaired (p < 0.001). RV dysfunction and low cardiorespiratory fitness were independent markers of death and need for HTx. Impairment of both ppVO2 and RV FW-LS had a strong additive impact on prognostic assessment in this cohort of patients with HFrEF.

Ecocardiografia Tridimensional na avaliação de endocardite de válvula nativa: um relato de caso e semelhança entre achados ecocardiográficos e cirúrgicos / Three-Dimensional transesophageal echocardiography in native valve endocarditis: a case report and similarities between echocardiography and surgical findings

A endocardite de valva nativa é uma doença incomum, complexa, e de alta morbimortalidade. Requer tratamento clínico prolongado, com várias complicações possíveis, e o seu tratamento cirúrgico é complexo e tecnicamente difícil. O ecocardiograma transtorácico e transesofágico são fundamentais na avaliação da doença, inclusive seus achados são parte dos critérios diagnósticos de endocardite. Adicionalmente, o ecocardiograma tridimensional (3D) contribui com detalhamento anatômico na avaliação das estruturas cardíacas acometidas pela doença. Mostramos um caso em que é ilustrado o papel da ecocardiografia no diagnóstico e avaliação de complicações da endocardite, comparando as imagens do ecocardiograma 3D pré-operatórias, com os achados durante o ato cirúrgico. (AU)

Native valve bacterial endocarditis is an uncommon, complex, and highly morbid disease that requires prolonged clinical treatment and challenging surgical interventions. Transthoracic and transesophageal echocardiography are paramount assessment tools whose findings are included in the diagnostic criteria. Three-dimensional echocardiography shows further realistic imaging details. Here we present a case demonstrating the role of echocardiography in the diagnosis of endocarditis and the identification of its complications to show how advanced imaging techniques may have a remarkable resemblance with in vivo surgical findings.

Right ventricular function during trastuzumab therapy for breast cancer.

Cardiotoxicity (CDT) is the main adverse effect related to trastuzumab (TTZ). The role of the right ventricle (RV) in this context is not clear. We aimed to evaluate the longitudinal changes in RV function during TTZ therapy and to determine RV function changes associated with subclinical CDT. Breast cancer patients underwent echocardiograms at the beginning of TTZ treatment (Exam 1) and every 3 months during the first year (Exams 2, 3, and 4). Subclinical CDT was defined as ≥ 12% relative reduction of left ventricle global longitudinal strain (LV GLS). Twenty-five women (52.1 ± 13.1 y-o) were included. We found a decrease in LV ejection fraction between the first and fourth exams (Ex1: 64.1% ± 4.9 vs Ex4: 60.9% ± 4.9, p = 0.003) and the LV GLS gradually decreased during follow-up (Ex1: - 20.6% ± 2.0; Ex2: - 19.4% ± 2.1; Ex3: - 19.2% ± 1.8; Ex4: - 19.0% ± 2.1, all p < 0.05). RV GLS changed from baseline to 3 month and to 6 month (Ex1: - 23.9% ± 1.6; Ex2: - 22.5% ± 2.1; Ex3: - 22.5% ± 2.3, all p < 0.05), and the RV Fractional Area Change was lower in the third exam (Ex1: 44.3% ± 6.6 vs Ex3: 39.9% ± 6.0, p = 0.004). We found subclinical CDT in 13 patients (52%); worsening in RV parameters did not differ between those with and without subclinical CDT. In this sample, the RV function decreased during TTZ therapy and the decrease was not associated to the observed LV cardiotoxicity.

Progression of Cardiovascular Manifestations in Adults and Children With Mucopolysaccharidoses With and Without Enzyme Replacement Therapy.

Background: Cardiovascular involvement is among the main features of MPS disorders and it is also a significant cause of morbidity and mortality. The range of manifestations includes cardiac valve disease, conduction abnormalities, left ventricular hypertrophy, and coronary artery disease. Here, we assessed the cardiovascular manifestations in a cohort of children and adults with MPS I, II, IV, and VI, as well as the impact of enzyme replacement therapy (ERT) on those manifestations. Methods: We performed a chart review of 53 children and 23 adults with different types of MPS that had performed echocardiograms from January 2000 until October 2018. Standardized Z scores were obtained for heart chamber sizes according to the body surface area. When available, echocardiographic measurements that were performed before ERT and at least 18 months after that date were used for the assessment of pre- and post-treatment parameters. Results: Left side valvular disease was a frequent finding, with mitral and aortic thickening being reported in most patients in all four MPS types. Left atrium dilatation was present in 26% of the patients; 25% had increased relative wall thickness; 28% had pulmonary hypertension. The cardiovascular involvement was, in general, more prevalent and more severe in adults than in children, including conduction disorders (40 vs. 16%), mitral stenosis (26 vs. 6%), aortic stenosis (13 vs. 4%), and systolic dysfunction (observed in only one adult patient). ERT promoted a significant reduction of the left ventricular hypertrophy parameters, but failed to improve valve abnormalities, pulmonary hypertension, and left atrial dilatation. Conclusions: Adult patients with MPS may develop severe cardiovascular involvement, not commonly observed in children, and clinicians should be aware of the need for careful monitoring and timely management of those potentially life-threatening complications. Our results also confirm the impact of long-term ERT on left ventricular hypertrophy and its limitations in reversing other prevalent cardiovascular manifestations.

Cardiovascular findings in classic homocystinuria.

OBJECTIVE: describe cardiovascular findings from echocardiograms and electrocardiograms in patients with Classic Homocystinuria. METHODS: this retrospective exploratory study evaluated fourteen subjects with Classic Homocystinuria (median age = 27.3 years; male n = 8, B6-non-responsive n = 9 patients), recruited by convenience sampling from patients seen Hospital de Clínicas de Porto Alegre (Brazil), between January 1997 and July 2020. Data on clinical findings, echocardiogram and electrocardiogram were retrieved from medical records. RESULTS: Eight patients presented some abnormalities on echocardiogram (n = 6) or electrocardiogram (n = 5). The most frequent finding was mild tricuspid regurgitation (n = 3), followed by mitral valve prolapse, mild mitral regurgitation, enlarged left atrium and aortic valve sclerosis (n = 2 patients each). Aortic root ectasia was found in one patient. Venous thrombosis was reported in six patients: deep vein thrombosis of lower limbs (n = 3), ischaemic stroke (n = 1), cerebral venous sinus thrombosis (n = 1) and pulmonary vein thrombosis (n = 1). CONCLUSION: mild valvulopathies seen to be common in patients with Classic Homocystinuria, but more studies regarding echocardiogram and electrocardiogram in this population are needed to draw absolute conclusions.

Association between electrocardiographic and echocardiographic atrial abnormalities and prognosis in cryptogenic stroke.

BACKGROUND AND PURPOSE: The role of atrial fibrillation in cryptogenic stroke (CS) is well known. However, the usefulness of left atrial (LA) electrical and morphological abnormalities to identify more disabling strokes in sinus rhythm patients is less studied. We evaluated the association between electrocardiographic P-wave abnormalities and echocardiographic LA measures with neurological disability in patients with cryptogenic stroke. METHODS: In a retrospective cohort, we included all consecutive hospitalized patients with cryptogenic stroke. Patients were classified according to modified Rankin scale at hospital discharge and at 3 months. LA abnormalities were identified by electrocardiographic (ECG) P-wave, axis and LA enlargement criteria, and by bidimensional echocardiograph through left atrial diameter and volume index. RESULTS: Among the 143 patients with CS (63.4 ± 14.2 years, 53% women), 70 patients were classified as non-disabling stroke (Rankin score < 2) and 73 patients as disabling stroke (Rankin score ≥ 2) at hospital discharge. On echocardiogram, more patients with disabling stroke presented with enlarged LA volume index (48% vs. 25%; p = 0.01). This difference remained significant after adjustment for age, gender, CHA2DS2-VASc and NIHSS scores (p = 0.02) and even when the LA volume index was analyzed as a continuous variable (p = 0.055). Also, enlarged LA volume index was more prevalent (52% vs. 25%; p = 0.03) among those with disabling stroke at 3 months after hospital discharge. Among ECG criteria, only the LA enlargement assessed by downward deflection was more prevalent in disabling stroke. CONCLUSION: Our study demonstrated an association between left atrial enlargement, assessed by downward deflection from ECG and volume index from echocardiogram, and more disabling cryptogenic strokes. This information could help to identify patients with poorer prognosis, or a subgroup where atrial cardiopathy may play a role in cardioembolic pathway.

Impaired Right Ventricular Function in Heart Transplant Rejection / Disfunção Ventricular Direita e Rejeição em Transplante Cardíaco

Abstract Background: The practice of screening for complications has provided high survival rates among heart transplantation (HTx) recipients. Objectives: Our aim was to assess whether changes in left ventricular (LV) and right ventricular (RV) global longitudinal strain (GLS) are associated with cellular rejection. Methods: Patients who underwent HTx in a single center (2015 - 2016; n = 19) were included in this retrospective analysis. A total of 170 biopsies and corresponding echocardiograms were evaluated. Comparisons were made among biopsy/echocardiogram pairs with no or mild (0R/1R) evidence of cellular rejection (n = 130 and n = 25, respectively) and those with moderate (2R) rejection episodes (n=15). P-values < 0.05 were considered statistically significant Results: Most patients were women (58%) with 48 ± 12.4 years of age. Compared with echocardiograms from patients with 0R/1R rejection, those of patients with 2R biopsies showed greater LV posterior wall thickness, E/e' ratio, and E/A ratio compared to the other group. LV systolic function did not differ between groups. On the other hand, RV systolic function was more reduced in the 2R group than in the other group, when evaluated by TAPSE, S wave, and RV fractional area change (all p < 0.05). Furthermore, RV GLS (−23.0 ± 4.4% in the 0R/1R group vs. −20.6 ± 4.9% in the 2R group, p = 0.038) was more reduced in the 2R group than in the 0R/1R group. Conclusion: In HTx recipients, moderate acute cellular rejection is associated with RV systolic dysfunction as evaluated by RV strain, as well as by conventional echocardiographic parameters. Several echocardiographic parameters may be used to screen for cellular rejection.

Resumo Fundamento: A prática de triagem para complicações tem proporcionado altas taxas de sobrevida entre pacientes que receberam transplante cardíaco (TC). Objetivos: Visamos avaliar se alterações no strain longitudinal global (SLG) do ventrículo esquerdo (VE) e do ventrículo direito (VD) estão associadas à rejeição celular. Métodos: Pacientes que foram submetidos à TC em um único centro (2015 - 2016; n = 19) foram incluídos nesta análise retrospectiva. Foram avaliados um total de 170 biópsias com ecocardiogramas correspondentes. Foram realizadas comparações entre pares de biópsia/ecocardiograma com nenhuma ou leve (0R/1R) evidência de rejeição celular (n = 130 e n = 25, respectivamente) e aqueles com episódios de rejeição moderada (2R) (n = 15). Foram considerados estatisticamente significativos os valores de p < 0,05. Resultados: A maioria dos pacientes eram mulheres (58%) com idade média de 48 ± 12,4 anos. Em comparação com os ecocardiogramas dos pacientes com rejeição 0R/1R, os pacientes com biópsias 2R apresentaram maior espessura da parede posterior do VE, relação E/e' e relação E/A, em comparação com o outro grupo. A função sistólica do VE não diferiu entre os grupos. Por outro lado, a função sistólica do VD foi reduzida no grupo 2R em comparação ao outro grupo, quando avaliada por TAPSE, onda S e variação fracional da área do VD. Adicionalmente, SLG VD (−22,97 ± 4,4% no grupo 0R/1R vs. −20,6 ± 4,9% no grupo 2R, p = 0,038) foi reduzido no grupo 2R, em comparação com o grupo 0R/1R. Conclusão: Em pacientes de TC, rejeição celular aguda moderada está associada à disfunção sistólica do VD, avaliado pelo strain do VD, bem como por parâmetros ecocardiográficos convencionais. Vários parâmetros ecocardiográficos podem ser utilizados para realizar triagem para rejeição celular.

Ecocardiografia na pré-hipertensão e hipertensão estágio I / Echocardiography in pre-hypertension and hypertension stage I

Fundamento: A pré-hipertensão e a hipertensão estágio I estão associadas ao remodelamento do ventrículo esquerdo (VE). No presente estudo, comparamos os parâmetros ecocardiográficos de lesão de órgãos-alvo pré-clínicos da hiper-tensão arterial em indivíduos com pré hipertensão e hipertensão estágio I selecionados a partir da mesma população. Métodos: Comparou-se as medidas ecocardiográficas basais dos participantes incluídos no estudo PREVER com pré-hi-pertensão (PREVER-prevention; n = 106) ou hipertensão estágio I (PREVER-treatment; n = 128). Investigou-se também as diferenças relacionadas ao sexo, verificadas nos parâmetros ecocardiográficos. Resultados: A pressão arterial sistólica e diastólica média mostrou-se significativamente maior no grupo hipertensão estágio I (141,0/90,4 mmHg) quando comparada com o grupo pré-hipertensão (129,3/81,5 mmHg, P<0,001 para ambos os grupos). A média de idade foi de 55 anos (30 a 70), com um número quase igual de homens e mulheres, dos quais 80% eram brancos e 7% tinham diabetes. A maioria dos parâmetros de massa do VE, dimensão do AE e função diastólica mostrou-se semelhante entre os grupos pré-hipertensão e hipertensão estágio I. Os indivíduos hipertensos apresentavam AE com maior diâmetro e maior espessura da parede posterior, além de menores velocidades laterais e, mesmo após ajuste para idade, sexo e índice de massa corporal. A análise em relação ao sexo mostrou VE com maior massa na hipertensão estágio I em comparação à pré-hipertensão apenas em mulheres (141,1 ± 34,1 gvs. 126,1 ± 29,1 g, P<0,05). Conclusões: Em indivíduos de meia-idade com baixo risco cardiovascular, as diferenças nos parâmetros ecocardiográficos relacionadas à lesão de órgãos-alvo são sutis entre a pré-hipertensão e a hipertensão estágio I, embora mulheres com hipertensão estágio I tenham VE com massa significativamente maior, o que pode indicar resposta adaptativa específica do sexo à pressão arterial em estágios iniciais de hipertensão

Diuretics are Similar to Losartan on Echocardiographic Target-Organ Damage in Stage I Hypertension. PREVER-Treatment Study.

Blood pressure (BP)-lowering therapy improves left ventricular (LV) parameters of hypertensive target-organ damage in stage II hypertension, but whether there is a drug-class difference in echocardiographic parameters in stage I hypertension patients is less often studied. In the PREVER treatment study, where individuals with stage I hypertension were randomized for treatment with diuretics (chlorthalidone/amiloride) or losartan, 110 participants accepted to participate in a sub-study, where two-dimensional echocardiograms were performed at baseline and after 18 months of antihypertensive treatment. As in the general study, systolic BP reduction was similar with diuretics or with losartan. Echocardiographic parameters showed small but significant changes in both treatment groups, with a favorable LV remodeling with antihypertensive treatment for 18 months when target blood pressure was achieved either with chlorthalidone/amiloride or with losartan as the initial treatment strategy. In conclusion, even in stage I hypertension, blood pressure reduction is associated with improvement in echocardiographic parameters, either with diuretics or losartan as first-drug regimens.

Resumo A terapia de redução da pressão arterial (PA) melhora os parâmetros do ventrículo esquerdo (VE) na lesão a órgãos-alvo causada pela condição hipertensiva na hipertensão de estágio II; no entanto, se existem ou não diferenças relacionadas à classe de medicamentos nos parâmetros ecocardiográficos de pacientes com hipertensão estágio I é menos frequentemente estudado. No estudo PREVER-treatment, em que indivíduos com hipertensão estágio I foram randomizados para tratamento com diuréticos (clortalidona/amilorida) ou losartana, 110 participantes aceitaram participar de um subestudo, no qual foram realizados ecocardiogramas bidimensionais basais e após 18 meses de tratamento anti-hipertensivo. Como no estudo geral, a redução da PA sistólica foi semelhante com diuréticos ou com losartana. Os parâmetros ecocardiográficos mostraram pequenas mas significativas alterações em ambos os grupos de tratamento, com um remodelamento favorável do VE com tratamento anti-hipertensivo por 18 meses, quando a pressão arterial alvo foi atingida com clortalidona/amilorida ou com losartana como estratégia inicial de tratamento. Em conclusão, mesmo na hipertensão estágio I, a redução da pressão arterial está associada à melhora nos parâmetros ecocardiográficos tanto com o uso de diuréticos ou losartana como primeiro esquema de tratamento farmacológico.

Echocardiographic Left Ventricular Reverse Remodeling After 18 Months of Antihypertensive Treatment in Stage I Hypertension. Results From the Prever-Treatment Study.

BACKGROUND: Antihypertensive treatment improves echocardiographic parameters of hypertensive target organ damage in stage II hypertension, but less is known about the effects in stage I hypertension. METHODS: In a cohort study nested in the randomized double-blind trial PREVER-treatment, 2-dimensional echocardiograms were performed in 110 individuals, aged 54.8 ± 7.9 years-old, with stage I hypertension at baseline and after 18 months of treatment with chlorthalidone/amiloride or losartan. RESULTS: At baseline, 66 (60%) participants had concentric remodeling. After antihypertensive treatment, systolic (SBP) and diastolic blood pressure (BP) were reduced from 141/90 to 130/83 mm Hg (P = 0.009). There was a significant reduction in left ventricular (LV) mass (LVM) index (82.7 ± 17.1 to 79.2 ± 17.5 g/m2; P = 0.005) and relative wall thickness (0.45 ± 0.06 to 0.42 ± 0.05; P < 0.001), increasing the proportion of participants with normal LV geometry (31% to 49%, P = 0.006). Left atrial (LA) volume index reduced (26.8 ± 7.3 to 24.9 ± 6.5 ml/m2; P = 0.001), and mitral E-wave deceleration time increased (230 ± 46 to 247 ± 67 ms; P = 0.005), but there was no change in other parameters of diastolic function. LVM reduction was significantly higher in the 2 higher tertiles of SBP reduction compared to the lower tertile. CONCLUSIONS: Treatment of patients with stage I hypertension for 18 months promotes favorable effects in the LA and LV remodeling. This improvement in cardiac end-organ damage might be associated with reduction of long term clinical consequences of hypertensive cardiomyopathy, particularly heart failure with preserved ejection fraction.
