RESUMO

Objectives: Aim of the study was to perform a systemic review and meta-analysis of the current case-control studies based on the assessment of the left ventricular (LV) systolic function with standard and advanced echocardiographic methods. Materials and methods: Objectives of the study, methods of statisticalanalysis, literature search strategy, inclusion andexclusion criteria, and outcome measurementswere defined according to Cochrane Collaborationsteps, 13 including recommendations for metaanalysisof observational studies in epidemiology (MOOSE). Results: A total of 850 papers were collected. Of those, eight papers (10 groups) including 174,442 SLE patients and 45,608,723 controls with heart failure (HF), 20 papers including 1,121 SLE patients and 1,010 controls with an evaluated LV ejection fraction (LVEF), and eight studies (nine groups) including 462 SLE patients and 356 controls with a measured LV global longitudinal strain (LVGLS) met the predefined inclusion criteria. HF rate in SLE patients was 2.39% (4,176 of 174,442 patients with HF), and SLE patients showed a 3.4 times higher risk for HF compared to controls. SLE patients had a lower LVEF compared to controls. LVGLS was more impaired in SLE patients compared to controls, irrespective of two-dimensional or three-dimensional speckle tracking echocardiography. Conclusion: Heart failure rate in SLE patients is high, and SLE patients showed a 3.4 times higher risk in patients with SLE compared to controls. LV systolic function, as measured by LVEF and LVGLS, is significantly affected in SLE patients, and LVGLS potentially represents a new tool for the early assessment of LV function.

RESUMO

BACKGROUND AND AIM: Pulmonary hypertension (PH) is a frequent complication of connective tissue disorders (CTDs), with a major impact on the prognosis of the disease. The aim of our study was to perform a systemic review and meta-analysis of published literature evaluating survival function in patients with systemic sclerosis (SSc) with and without PH and to compare survival function between patients with SSc, systemic lupus erythematosus (SLE), other CTDs, and conditions associated with PH. METHODS: The established protocol of the Cochrane Collaboration Steps and meta-analysis of observational studies in epidemiology recommendations (MOOSE) were used. RESULTS: 7 studies, including 1470 SSc-PH patients and 1368 SSc patients without PH, and 4 studies, including 108 SLE-PH patients and 1288 SLE patients without PH, assessed survival function were selected. Six studies (including 777 SSc, 249 SLE, 90 idiopathic pulmonary arterial hypertension (IPAH) and 29 primary Sjogren's syndrome patients) comparing survival function in different subgroups of patients with confirmed PH were included. SSc patients with PH showed the worst survival as compared to SSc patients without PH [OR (95% CI) 3.70 (2.42-5.67); p<0.00001]. The same pattern was observed in patients with SLE. SSc patients with PH were characterized by lower survival function compared to other reasons for PH, including SLE [OR (95% CI) 2.76 (1.95-3.91); p<0.00001]. CONCLUSIONS: Patients with SSc-PH are characterized by significantly lower survival function as compared to SSc patients without PH. Among the different entities of PH, SSc shows the worst survival, underlining prognostic significance of detection and evaluation of PH according to the currently established approach.

RESUMO

BACKGROUND: Cardiovascular involvement is one of the leading causes of mortality in systemic sclerosis (SSc) and is reported to be higher in men as compared with women. However, the cause of this difference is largely unknown. The objective of this study was to assess sex differences in echocardiographic characteristics, including left ventricular global longitudinal strain (LV GLS), as a potential explanation of sex differences in outcomes. METHODS: A total of 746 patients with SSc from four centres, including 628 (84%, 54±13 years) women and 118 (16%, 55±15 years) men, were evaluated with standard and advanced echocardiographic examinations. The independent association of the echocardiographic parameters with the combined endpoint of cardiovascular events-hospitalisation/death was evaluated. RESULTS: Men and women with SSc showed significant differences in disease characteristics and cardiac function. After adjusting for the most important clinical characteristics, while LV ejection fraction and diastolic function were not significantly different anymore, men still presented with more impaired LV GLS as compared with women (-19% (IQR -20% to -17%) vs -21% (IQR: -22% to -19%), p<0.001). After a median follow-up of 48 months (IQR: 26-80), the combined endpoint occurred in 182 patients. Men with SSc experienced higher cumulative rates of cardiovascular events-hospitalisation/mortality (χ2=8.648; Log-rank=0.003), and sex differences were maintained after adjusting for clinical confounders, but neutralised when matching the groups for LV GLS. CONCLUSION: In patients with SSc, male sex is associated with worse cardiovascular outcomes even after adjusting for important clinical characteristics. LV GLS was more impaired in men as compared with women and potentially explains the sex difference in cardiovascular outcomes.

RESUMO

AIMS: Aortic stenosis (AS) induces left atrial (LA) remodelling through the increase of left ventricular (LV) filling pressures. Peak LA longitudinal strain (PALS), reflecting LA reservoir function, has been proposed as a prognostic marker in patients with AS. Feature-tracking (FT) multi-detector computed tomography (MDCT) allows assessment of LA strain from MDCT data. The aim of this study is to investigate the association between PALS using FT MDCT and survival in patients with severe AS who underwent transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: A total of 376 patients (mean age 80 ± 7 years, 53% male) who underwent MDCT before TAVI and had suitable data for assessment of PALS using dedicated FT software, were included. The patients were classified into four groups according to PALS quartiles; PALS > 19.3% (Q1, highest reservoir function), 15.0-19.3% (Q2), 9.1-14.9% (Q3), and ≤9.0% (Q4, lowest reservoir function). The primary outcome was all-cause mortality. During a median of 45 (22-68) months follow-up, 148 patients (39%) died. On multivariable Cox regression analysis, PALS was independently associated with all-cause mortality [hazard ratio (HR): 1.044, 95% confidence interval (CI): 1.012-1.076, P = 0.006]. Compared with patients in Q1, patients in Q3 and Q4 were associated with higher risk of mortality after TAVI [HR: 2.262 (95% CI: 1.335-3.832), P = 0.002 for Q3, HR: 3.116 (95% CI: 1.864-5.210), P < 0.001 for Q4]. CONCLUSION: PALS assessed with FT MDCT is independently associated with all-cause mortality after TAVI.

RESUMO

Several studies have shown an association between aortic stenosis (AS) and coronary atherosclerosis. This study aimed to evaluate the gender differences in aortic valve calcium (AVC) and coronary artery calcium (CAC) and the association between CAC and all-cause mortality in patients with severe AS. A total of 260 patients (80 ± 7 years, 39% men) with severe AS who were scheduled for transcatheter aortic valve implantation (TAVI) were included. AVC and CAC before TAVI were assessed by noncontrast cardiac computed tomography. Patients with coronary intervention or aortic valve replacement before cardiac computed tomography were excluded. Standard reference values of CAC score were used to classify the percentile groups and the distribution of AVC was assessed. The primary end point was all-cause mortality. In men, the AVC score was 3,911 Hounsfield units (HUs) (interquartile range [IQR] 2,525 to 5,259) and in women, 2,409 HU (IQR 1,588 to 3,359) (p <0.001). CAC score in men was 824 HU (IQR 328 to 1,855) and in women, 478 HU (IQR 136 to 962) (p <0.001). In men, the AVC score increased along with the CAC score, whereas in women, the AVC score was similar across the CAC percentile groups. During a median follow-up of 1,095 days, 59 patients (23%) died. No significant gender-difference was seen in all-cause mortality for CAC score (p = 0.187). Men with severe AS show higher AVC and CAC scores than women. Although the pattern of CAC distribution was similar between men and women, the AVC score increased along with the CAC score in men; whereas, in women, the AVC score remained similar across the various percentiles. CAC score was not associated with cumulative mortality in patients with severe AS who underwent TAVI.

RESUMO

Systemic sclerosis (SSc) is a chronic autoimmune disorder with unknown triggering factors, and complex pathophysiologic links which lead to fibrosis of skin and internal organs, including the heart, lungs, and gut. However, more than 100 years after the first description of cardiac disease in SSc, sclerodermic cardiomyopathy (SScCmp) is an underrecognized, occult disease with important adverse long-term prognosis. Laboratory tests, electrocardiography (ECG) and cardiovascular multimodality imaging techniques (transthoracic 2D and 3D echocardiography, cardiac magnetic resonance (CMR), and novel imaging techniques, including myocardial deformation analysis) provide new insights into the cardiac abnormalities in patients with SSc. This state-of-the-art review aims to stratify all the cardiac investigations needed to diagnose and follow-up the SScCmp, and discusses the epidemiology, risk factors and pathophysiology of this important cause of morbidity of the SSc patient.

RESUMO

Cardiac involvement is the main cause of death in Becker muscular dystrophy (BMD). Identification of left ventricular (LV) function is crucial, but standard echocardiographic measurements such as LV ejection fraction (LVEF) might not be sensitive enough to detect early myocardial dysfunction. We explored the value of LV global longitudinal strain (GLS) as a more accurate echocardiographic parameter to detect and monitor LV dysfunction in BMD. Furthermore, we studied possible factors associated with LV dysfunction and progression. A total of 40 patients with BMD (age 39.0 ± 13.2 years) and 21 matched controls were included. Clinical variables, pulmonary tests, serum biomarkers, and echocardiograms were collected at baseline and after 2 years. LV systolic function was assessed by LVEF and LV GLS; a significant progression in LV dysfunction was defined as an absolute LV GLS deterioration ≥15%. Responsiveness to cardiac disease progression was determined using standardized response means. Patients showed impaired LVEF and LV GLS compared with controls (p <0.001). Of interest, 31 patients (77.5%) showed impaired LV GLS (defined as greater than -18%), whereas only 24 patients (60%) had reduced LVEF. LV GLS and LVEF correlated with troponin I (ρ = 0.553 and -0.523) and N-terminal pro-b-type natriuretic peptide (ρ = 0.506 and -0.585), but not with skeletal muscle or pulmonary function. At follow-up (2.0 ± 0.5 years, n = 29), LV GLS worsened significantly (-1.3 ± 0.8%, p = 0.002, standardized response mean = 0.70, annually = 0.60%), whereas LVEF remained stable. No risk factors for LV dysfunction progression were identified. In BMD, LV GLS is frequently impaired and shows deterioration over time compared with LVEF. LV GLS could be used as a more sensitive parameter to identify and monitor LV dysfunction.

RESUMO

AIMS: Peak left atrial longitudinal strain (PALS) is a marker of the left atrial (LA) reservoir function. Novel feature tracking (FT) software allows assessment of LA strain from multidetector computed tomography (MDCT) data. This study aimed at evaluating the agreement between speckle tracking echocardiography (STE) and FT MDCT for the measurement of PALS in patients with sinus rhythm (SR) and with atrial fibrillation (AF). METHODS AND RESULTS: The current study included 318 patients (80 ± 7 years, 54% male) with dynamic MDCT data acquired prior to transcatheter aortic valve implantation. PALS was measured by transthoracic echocardiography using STE (PALSecho) and MDCT using dedicated FT software (PALSCT). In the overall population, the median values of PALSecho and PALSCT were 19.0 [interquartile range (IQR) 12.0-25.0] % and 15.3 (IQR 9.2-19.7) %, respectively. High correlation between PALSecho and PALSCT was observed (r = 0.789, P < 0.001) with a mean bias of -3.7%. The correlation between PALSecho and PALSCT was better among patients with SR (N = 258; r = 0.704, P < 0.001) as compared to patients with AF (N = 60; r = 0.622, P < 0.001). CONCLUSION: PALSecho and PALSCT showed a good agreement in patients with severe aortic stenosis (AS) regardless of the cardiac rhythm. FT MDCT may be an important adjuvant modality for assessing LA reservoir function in patients with severe AS.

RESUMO

BACKGROUND: The study investigators previously reported that moderate aortic stenosis (AS) is associated with a poor prognosis in patients with heart failure (HF) with reduced left ventricular ejection fraction (LVEF) (HFrEF). However, the respective contribution of moderate AS versus HFrEF to the outcomes of these patients is unknown. OBJECTIVES: This study sought to determine the impact of moderate AS on outcomes in patients with HFrEF. METHODS: The study included 262 patients with moderate AS (aortic valve area >1.0 and <1.5 cm2; and peak aortic jet velocity >2 and <4 m/s, at rest or after dobutamine stress echocardiography) and HFrEF (LVEF <50%). These patients were matched 1:1 for sex, age, estimated glomerular filtration rate, New York Heart Association functional class III to IV, presence of diabetes, LVEF, and body mass index with patients with HFrEF but no AS (i.e., peak aortic jet velocity <2 m/s). The endpoints were all-cause mortality and the composite of death and HF hospitalization. RESULTS: A total of 262 patients with HFrEF and moderate AS were matched with 262 patients with HFrEF and no AS. Mean follow-up was 2.9 ± 2.2 years. In the moderate AS group, mean aortic valve area was 1.2 ± 0.2 cm2, and mean gradient was 14.5 ± 4.7 mm Hg. Moderate AS was associated with an increased risk of mortality (hazard ratio [HR]: 2.98; 95% confidence interval [CI]: 2.08 to 4.31; p < 0.0001) and of the composite of HF hospitalization and mortality (HR: 2.34; 95% CI: 1. 72 to 3.21; p < 0.0001). In the moderate AS group, aortic valve replacement (AVR) performed in 44 patients at a median follow-up time of 10.9 ± 16 months during follow-up was associated with improved survival (HR: 0.59; 95% CI: 0.35 to 0.98; p = 0.04). Notably, surgical AVR was not significantly associated with improved survival (p = 0.92), whereas transcatheter AVR was (HR: 0.43; 95% CI: 0.18 to 1.00; p = 0.05). CONCLUSIONS: In this series of patients with HFrEF, moderate AS was associated with a marked incremental risk of mortality. AVR, and especially transcatheter AVR during follow-up, was associated with improved survival in patients with HFrEF and moderate AS. These findings provide support to the realization of a randomized trial to assess the effect of early transcatheter AVR in patients with HFrEF and moderate AS.

RESUMO

The aim of this study is to evaluate the agreement between three-dimensional (3D) transesophageal echocardiography (TEE) and multidetector computed tomography (MDCT) for assessing mitral annular (MA) dimensions. A total of 105 patients (79 ± 9 years old, 52% male) who underwent clinically indicated 3D TEE and MDCT feasible for MA geometrical assessment were included. Using dedicated semi-automated postprocessing software, MA geometry, including mitral annular area (MAA), perimeter, septal-lateral (SL) diameter, and inter-trigonal (TT) diameter, was evaluated using 3D TEE and MDCT. Compared to 3D TEE, MAA, perimeter, and SL distance measured on MDCT data were larger (9.9 ± 3.0 vs. 9.3 ± 3.1 cm2 for MAA; 115 ± 18 vs. 108 ± 18 mm for perimeter; and 35 ± 5 vs. 32 ± 5 cm for SL distance, all p < 0.001). By contrast, the TT distance was comparable between MDCT and 3D TEE (26 ± 4 vs. 26 ± 4 cm, p = 0.258). The correlations of all the MA dimensions were good to excellent between the two modalities (R = 0.911 for MAA, 0.890 for perimeter, 0.739 for TT distance, and 0.857 for SL distance, respectively, all p < 0.001). This study showed good agreement between 3D TEE- and MDCT-derived MA measurements although MDCT systematically provided larger MAA, perimeter, and SL distance compared with 3D TEE.

RESUMO

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with potential cardiovascular involvement. The aim of this study was to assess left ventricular (LV) systolic function in a large cohort of patients with SLE using standard echocardiographic measurements and global longitudinal strain (GLS) by two-dimensional speckle-tracking analysis. Furthermore, the association between echocardiographic parameters and the occurrence of cardiovascular events was assessed. METHODS: A total of 102 patients with SLE (88% women; mean age, 43 ± 14 years) undergoing a dedicated multidisciplinary assessment were analyzed, including echocardiography, at the time of their first visit. A control group consisted of 50 age- and sex-matched healthy subjects. RESULTS: Compared with control subjects, patients with SLE showed impaired LV systolic function on the basis of LV ejection fraction (51 ± 6% vs 62 ± 6%, P < .001) and by LV GLS (-15 ± 3% vs -19 ± 2%, P < .001). During a median follow-up period of 2 years (interquartile range, 1-6 years), 38 patients (37%) developed cardiovascular events. Kaplan-Meier survival curves showed that patients with SLE with more impaired LV GLS (on the basis of the median value of -15%) experienced higher cumulative rates of cardiovascular events compared with those with less impaired LV GLS (χ2 = 8.292, log-rank P = .004). On multivariate Cox regression analysis, LV GLS demonstrated an independent association with cardiovascular events (hazard ratio, 2.171; 95% CI, 1.015-4.642; P = .046), whereas LV ejection fraction was not significantly associated with the outcome. CONCLUSIONS: In patients with SLE, LV systolic function as measured by LV GLS is significantly impaired and associated with cardiovascular events, potentially representing a new tool to improve risk stratification in these patients.

RESUMO

Aortic stenosis (AS) and renal dysfunction share risk factors and often occur simultaneously. The influence of renal dysfunction on the prognosis of patients with various grades of AS has not been extensively described. The present study aimed to assess the prognostic implications of renal dysfunction in a large cohort of patients with aortic sclerosis and patients with various grades of AS. Patients diagnosed with various grades of AS by transthoracic echocardiography were assessed and divided according to renal function by estimated glomerular filtration rate (eGFR). The occurrence of all-cause mortality (primary end point) and aortic valve replacement (AVR) was noted. Of 1,178 patients (mean age 70 ± 13 years, 60% male), 327 (28%) had aortic sclerosis, 86 (7%) had mild AS, 285 (24%) had moderate AS, and 480 (41%) had severe AS. Renal dysfunction (eGFR <60 ml/min/1.73 m2) was present in 440 (37%) patients, and moderate to severe AS was observed more often in these patients compared to patients without (70 vs 62%, respectively; p = 0.008). After a median follow-up of 95 [31 to 149] months, 626 (53%) patients underwent AVR and 549 (47%) patients died. Severely impaired renal function (eGFR <30 ml/min/1.73 m2) and AVR were independently associated with all-cause mortality after correcting for AS severity. In conclusion, renal dysfunction is highly prevalent in patients with various grades of AS. After correcting for AS severity and AVR, severely impaired renal function (eGFR <30 ml/min/1.73 m2) was independently associated with all-cause mortality. Independent of renal function, AVR was associated with improved survival.

RESUMO

Computed tomography plays a central role in the evaluation of patients with severe aortic stenosis who underwent transcatheter aortic valve implantation (TAVI). Advances in left ventricular (LV) analysis with multidetector row computed tomography (MDCT) permit measurement of LV global longitudinal strain (GLS). The present study aimed at evaluating the association between feature tracking (FT) MDCT derived LV GLS and all-cause mortality in patients treated with TAVI. A total of 214 patients with severe aortic stenosis (51% male, 80 ± 7 years) who underwent TAVI and with dynamic MDCT data allowing LV GLS measurement with novel FT algorithm were included. LV GLS was measured at baseline and were divided according to a previously published cut-off value of LV GLS associated with all-cause mortality (≤-14% [more preserved LV systolic function] vs >-14% [more impaired LV systolic function]). Patients were followed for the occurrence of all-cause mortality. Mean FT MDCT-derived LV GLS was -12.5 ± 4%. During a median follow-up of 45 months (interquartile range: 29 to 62 months), 67 (31%) patients died. The cumulative rate of all-cause mortality for the patients with FT MDCT-derived LV GLS ≤-14% was 15% versus28% for the patients with FT MDCT-derived LV GLS >-14%, Log rank p = 0.001). FT MDCT-derived LV GLS was independently associated with all-cause mortality (hazard ratio: 0.851; 95% confidence interval: 0.772 to 0.937; p = 0.001). In conclusion, impaired FT MDCT-derived LV GLS is independently associated with all-cause mortality in patients treated with TAVI. Besides aortic valve area and calcification, FT MDCT-derived LV GLS is an important prognostic marker.

RESUMO

BACKGROUND: Left ventricular (LV) systolic function is a prognostic factor in patients with severe aortic stenosis (AS). Multi-detector row computed tomography (MDCT) data are key in the evaluation of patients undergoing transcatheter aortic valve implantation (TAVI) and when acquired retrospectively, LV systolic function can be assessed. Novel software permits assessment of LV global longitudinal strain (GLS) from MDCT data. OBJECTIVES: The present study investigated the feasibility of feature tracking MDCT-derived LV GLS and its agreement with echocardiographic LV GLS in patients treated with TAVI. METHODS: LV GLS was measured on transthoracic echocardiography using speckle tracking analysis and on dynamic MDCT using feature tracking technology. Agreement between the measurements of two different modalities was assessed using Bland-Altman analysis. RESULTS: A total of 214 patients (51% male, mean age: 80 ± 7 years) were analysed. Mean LV GLS on echocardiography was -13.91 ± 4.32%, whereas mean feature tracking MDCT-derived GLS was -12.46 ± 3.97%. Correlation of measurements between feature tracking MDCT-derived LV GLS and echocardiographic LV GLS demonstrated a large effect size (r = 0.791, p < 0.001). On Bland-Altman analysis, feature tracking MDCT-derived strain analysis underestimated LV GLS compared to echocardiography with a mean difference of 1.44% (95% limits of agreement -3.85% - 6.73%). CONCLUSIONS: Assessment of LV GLS on dynamic feature tracking MDCT data is feasible in TAVI patients. Compared to speckle tracking echocardiography, feature tracking MDCT underestimates the value of LV GLS.

RESUMO

BACKGROUND: After transcatheter aortic valve replacement (TAVR), changes in left ventricular (LV) function are partly influenced by the vascular afterload. The burden of thoracic aorta calcification is a component of vascular afterload. OBJECTIVE: To assess changes in LV systolic function measured with global longitudinal strain (GLS) in relation to the burden of thoracic aorta calcification in patients with severe aortic stenosis treated with TAVR. METHODS: Calcification of the thoracic aorta was estimated on noncontrast computed tomography in 210 patients (50% male, 80 ± 7 years) undergoing TAVR. Conventional and speckle-tracking echocardiography were performed at baseline (prior to TAVR) and 3-6 months and 12 months after TAVR. Patients were divided according to tertiles of calcification burden of the thoracic aorta. RESULTS: At baseline, patients within the first tertile of thoracic aorta calcification (0-1,395 Hounsfield Units, HU) had better LV systolic function (LV ejection fraction [LVEF], 47% ± 9%; and LV GLS, -15% ± 5%) as compared with the second tertile (1,396-4,634 HU; LVEF, 46% ± 10%; and LV GLS, -14% ± 4%), and the third tertile (>4,634 HU; LVEF, 44% ± 10%; and LV GLS, -12% ± 4%). During follow-up, patients within tertile 1 of calcification of thoracic aorta achieved significantly better LV systolic function and larger regression of LV mass at 12 months of follow-up than patients within the other tertiles. This pattern was more pronounced in patients with reduced LVEF at baseline. CONCLUSIONS: After TAVR, LVEF and GLS improves and LV mass index is reduced significantly at 3-6 and 12 months of follow-up. Patients within the lowest burden of thoracic aorta calcification achieved the best values of LVEF and LV GLS at 1-year follow-up.
