Maternal Right Ventricular and Left Atrial Function in Uncomplicated Twin Pregnancies: A Longitudinal Study. J Clin Med 2022; 11:5432. [PMID: 36143080 PMCID: PMC9503833 DOI: 10.3390/jcm11185432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 09/11/2022] [Accepted: 09/13/2022] [Indexed: 11/25/2022] Open
Abstract
Objective: The knowledge regarding maternal cardiovascular hemodynamic adaptation in twin pregnancies is incomplete. We performed a longitudinal investigation of maternal right ventricular (RV) and left atrial (LA) function in a cohort of uncomplicated twin pregnancies compared to singleton pregnancies. Study design: Healthy women with uncomplicated twin pregnancies were prospectively enrolled and assessed by transthoracic echocardiography at 10−15 weeks’ (w) gestation (T1), 19-26 w gestation (T2), and 30−38 w gestation (T3). Subjects with uneventful singleton pregnancies were selected as controls at the same gestational ages. Cardiac findings were compared to those of women with uneventful singleton gestations. RV systolic and diastolic functions were assessed by conventional echocardiography (FAC, TAPSE, sPAP, E, A, DT) and tissue Doppler imaging (TDI) (E’, A’, S’, IVA, IVCT, IVRT, ET, MPI), and LA dimensions were calculated. Speckle-tracking imaging was also applied to evaluate RV global longitudinal strain and LA 2D strains (at LV end-systole (LAS) and at atrial contraction (LAA)). Results: Overall, 30 uncomplicated twin and 30 uncomplicated singleton pregnancies were included. Regarding maternal RV function in twins, all the parameters (FAC, TAPSE, sPAP, E, A, E/A, DT, E/E’, IVA, IVCT, MPI and 2D longitudinal strain) were almost stable throughout gestation, with the exception of the TDI findings (E’ decreased from T1 to T3 (p = 0.03), while E’/A’ increased from T1 to T2 and then decreased (p = 0.01); A’ and basal S’ increased (p = 0.04 and p = 0.03, respectively), while IVRT and ET significantly decreased (p = 0.009 and p = 0.007, respectively)). These findings were similar to those found for singleton pregnancies. LA dimensions significantly increased throughout gestation in both twins and singletons (p < 0.001), without intergroup difference. LA strains did not vary during either twin or singleton pregnancies, except for LAA in T1, which was higher among twins than among singletons. Conclusion: Maternal RV and LA function in uncomplicated twin pregnancies does not seem to undergo more significant changes than in singletons, being characterized by similar findings in RV systolic and diastolic functions, as well as LA dimensions and strains.

Maternal Left Ventricular Function in Uncomplicated Twin Pregnancies: A Speckle-Tracking Imaging Longitudinal Study. J Clin Med 2022; 11:jcm11185283. [PMID: 36142928 PMCID: PMC9504023 DOI: 10.3390/jcm11185283] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 08/28/2022] [Accepted: 09/06/2022] [Indexed: 12/04/2022] Open
Abstract
Objective: The knowledge of maternal cardiovascular hemodynamic adaptation in twin pregnancies is incomplete. We aimed to longitudinally investigate maternal left ventricular (LV) function in uncomplicated twin pregnancies. Methods: 30 healthy and uncomplicated twin pregnant women and 30 controls with normal singleton pregnancies were prospectively enrolled to undergo transthoracic echocardiography at 10–15 week’s gestation (w) (T1), 19–26 w (T2) and 30–38 w (T3). LV dimensions and volumes, as well as LV ejection fraction (LVEF), mass (LVM) and diastolic parameters (at transmitral pulsed wave Doppler and mitral annular plane tissue Doppler), were calculated. Speckle-tracking imaging was also applied to evaluate LV global longitudinal (GLS), radial and circumferential 2D strains. Results: During twin pregnancy, maternal LV dimensions, volumes and LVM had an increasing trend from T1 to T3, similar to singletons, while LVEF remained stable. There was LV remodeling/hypertrophy in 50% of women at T2 and T3 in both groups. Diastolic function had a worsening trend from T1 to T3 with no differences between twins and singletons, except for higher LV filling pressure (i.e., E/E′) at T2 in twins. Two-dimensional strains did not vary during gestation in either group, except for a linear trend to increase (i.e., worsen) GLS in singletons. Radial and circumferential 2D strains were impaired in about half of the women at each trimester, while GLS was altered in one-fourth/one-third of them in both groups. Conclusion: Maternal LV geometry, dimensions and function are significantly impaired during twin pregnancies, in particular in the second half of gestation, with no significant differences compared to singletons.

Abstract
OBJECTIVE There is scant information about maternal cardiovascular hemodynamic change during twin pregnancies. Aim of the study is to investigate longitudinal changes in maternal arterial stiffness, elastic aortic properties and ventricular-arterial coupling (VAC) in uncomplicated twin pregnancies compared to singleton ones. APPROACH In this prospective longitudinal study, we performed applanation tonometry and transthoracic echocardiography in the first (T1; 10-15 weeks' gestation (w)), second (T2; 19-26 w) and third trimesters (T3; 30-38 w) in women with uncomplicated twin pregnancies, both monochorionic and dichorionic. Heart-rate-corrected augmentation index (AIx@75) was studied as indicator of arterial stiffness. Aortic diameters and elastic properties were calculated. VAC was defined as the ratio between aortic elastance (Ea) and left ventricular end-systolic elastance (Ees). Finally, stroke volume (SV), cardiac output (CO) and total vascular resistance (TVR) were evaluated. The findings were compared to those of women with uncomplicated singleton pregnancies. MAIN RESULTS Thirty women with twin gestations (11 monochorionic) and 30 singleton controls were obtained for analysis. Blood pressure and TVR significantly decreased from T1 to T2 and then rose in T3, with higher values in twins than in singletons. AIx@75 showed the same trend in both groups with lower values at T2 in twins. SV and CO linearly increased throughout gestation with no significant intergroup difference. Aortic diameters and elastic properties remained stable throughout gestation, with no significant intergroup differences. Both Ea and Ees were greater (i.e. worse) in twins than in singletons at T1 and T3, showing a significant linear trend towards reduction in the two groups, meaning lower vascular and ventricular loads. Using longitudinal analysis blood pressure, TVR, Ea and Ees depended from both multiple gestation and gestational age. SIGNIFICANCE In twins, maternal hemodynamics does not seem to undergo more significant changes than in singletons being characterized by higher blood pressures and TVR with no differences in CO, SV, aortic dimensions and elastic properties. Despite VAC is maintained within its normal range, total vascular load (i.e., Ea) resulted higher in twin than singleton pregnancies throughout gestation. It is conceivable that these findings may represent one of the underlying cause for the increased risk of adverse obstetric outcomes described in multiple gestations.

Elastic properties of ascending aorta and ventricular-arterial coupling in women with previous pregnancy complicated by HELLP syndrome. J Hypertens 2020; 37:356-364.

Abstract
OBJECTIVE To compare the elastic properties of the ascending aorta and ventricular-arterial coupling (VAC) in women with a previous pregnancy complicated by hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome, women who experienced preeclampsia, and healthy controls. METHODS Women with a history of preeclampsia (n = 60) or HELLP syndrome (n = 49) and matched healthy controls (n = 60) underwent transthoracic echocardiography at 6 months to 4 years after delivery. Aortic M-mode and tissue Doppler imaging (TDI) parameters were measured. Aortic diameters were assessed at end-diastole at four levels: Valsalva sinuses, sinotubular junction, tubular tract, and aortic arch. Aortic compliance, distensibility, stiffness index, Peterson's elastic modulus, pulse-wave velocity, and M-mode strain were calculated using standard formulae. Aortic expansion velocity, early and late diastolic retraction velocities, and peak systolic tissue strain (TDI-ε) were determined. VAC was defined as the ratio between aortic elastance (Ea) and left ventricular end-systolic elastance (Ees). All women were free from cardiovascular risk factors. RESULTS Women with a history of HELLP syndrome showed larger aortas than those with previous preeclampsia or controls, probably related to a higher blood pressure. Aortic elastic properties, including Ea, were similar between HELLP and preeclampsia groups, even comparing cases with early-onset preeclampsia and HELLP. In contrast, Ees was more impaired in the HELLP group than in the other two. Consequently, about one-quarter of women who experienced HELLP syndrome had a pathological VAC, whereas only 5% of previously preeclamptic patients did. Multivariate analysis confirmed the association between HELLP syndrome and VAC, whereas other parameters including aortic compliance, distensibility, stiffness index, and elastic modulus are linked only to gestational age at preeclampsia onset, ad also Ea and Ees did. CONCLUSIONS We found a significant overlap between the aortic elastic properties in women with a history of preeclampsia and those with a previous HELLP syndrome, suggesting a common pathophysiologic pathway. However, women who experienced HELLP syndrome showed a higher blood pressure than other cases and controls, probably determining larger aortas. In addition, VAC was more altered in the HELLP group than in the others because of a higher Ea and a lower Ees.

Abstract
BACKGROUND Accelerated atherosclerosis, responsible for premature cardiovascular disease, has been estimated to develop or progress in 10% of systemic lupus erythematosus (SLE) patients each year and to be 6-fold more frequent in SLE compared with the general population. The mechanisms underlying accelerated atherosclerosis in SLE are complex and involve classical and "non-classical" cardiovascular risk factors. Subclinical and disseminated atherosclerosis is associated with endothelial dysfunction and arterial stiffness. OBJECTIVE The aim of this review is to analyze the association between SLE and endothelial dysfunction. RESULTS AND CONCLUSION Different mechanisms have been proposed to explain the prevalence of endothelial dysfunction in SLE, which are briefly reported in this review: impaired clearance of apoptotic cells, oxidative stress markers, B cell activation with different circulating autoantibodies, different subtypes of T lymphocytes, cytokine cascade. Several studies and meta-analyses show a significant trend towards a prevalence of subclinical accelerated atherosclerosis in patients with SLE compared with healthy controls, since childhood. Based on general considerations, we suggest a multidisciplinary management to assess endothelial dysfunction at the diagnosis of the disease and to periodically search for and treat the traditional cardiovascular risk factors. Prospective studies are needed to confirm the benefits of this management.

Abstract
Strain echocardiography is able to detect subclinical ventricular systolic and diastolic dysfunction. Prolonged survival to cystic fibrosis favors heart and vessel involvement. The purpose of the present study was to compare clinically stable adult patients affected by cystic fibrosis without overt pulmonary hypertension with controls to evaluate right ventricular (RV) systolic and diastolic function by means of strain and tissue Doppler imaging (TDI), respectively. 22 adults affected by cystic fibrosis and 24 healthy volunteers matched for age and sex were enrolled. None had known cardiovascular risk factors or overt pulmonary hypertension. All people underwent blood pressure measurement and transthoracic echocardiography. Cystic fibrosis patients showed higher sPAP [median 25 (IQR 21-30) vs 22 (22-22) mmHg; p = 0.02] and more frequent RV diastolic dysfunction (p < 0.001). Among cases, some RV systolic parameters were significantly altered than controls, such as TAPSE [20 (18-24) vs. 23 (21-28) mm; p = 0.001], FAC [34 (26-44) vs. 49 (48-50)%; p < 0.001], midwall tissue strain [- 25.0 (- 31.3 to - 22.8) vs. - 30.5 (- 31.8 to - 29.3)%; p = 0.03], apical tissue strain [- 22 (- 29.3 to - 19.0) vs. - 30.5 (- 32.8 to - 28.3)%; p = 0.001] and 2D strain [- 22.0 (- 25.1 to - 19.0) vs. - 29.5 (- 31.8 to - 27.3)%; p < 0.001]. Finally, 2D strain correlated with spirometric FEV1 (ρ = - 0.463, p = 0.03) and nearly with FEF25-75% (ρ = - 0.393, p = 0.07). Our study confirmed a RV subclinical systo-diastolic dysfunction in clinically stable patients affected by cystic fibrosis without overt pulmonary hypertension nor cardiovascular risk factors. This may be due to systemic inflammation and temporary recurrent pulmonary hypertension. We retain that RV 2D strain and TDI echocardiography could become an important tool in the follow-up of these patients.

Abstract
Resting heart rate (HR) is considered a powerful predictor of mortality both in healthy subjects and in cardiovascular (CV) patients, including those affected by heart failure (HF). Its reduction below 70 bpm is the treatment target in chronic HF with reduced ejection fraction (HFrEF) when sinus rhythm is present. In acute HF (AHF) HR is usually elevated but its role as risk marker is still unknown. Notably, in unstable patients, beta-blockers can be reduced or stopped, thus enhancing this phenomenon. Moreover, some data in literature suggest that HR reduction during hospitalization or HR at discharge or in the vulnerable phase after it are more predictive of early-term events and may be therapeutic targets. On the other hand, ivabradine is a pure HR-lowering drug with no effects on inotropism. Its role in the AHF setting has been recently investigated and is the object of this review.

Abstract
Wellens' syndrome is a pattern of electrocardiographic T-wave changes seen in the precordial leads in patients with unstable angina. Two different patterns have been described. Type A presents with biphasic T-waves in V2-V3 and type B presents with symmetrical deep T-wave inversions in V2-V3. The etiology is related to a critical stenosis in the proximal left anterior descending artery (LAD). We describe a patient who presented at our emergency department with intermittent chest pain and showing Wellens' pattern T-wave inversions in the precordial leads of the electrocardiogram. She was found to have 95% stenosis in mid LAD.

Abstract
Increasing survival from cystic fibrosis show untypical systems involvement, such as cardiocirculatory. In particular, the presence of CFTR in smooth muscle and endothelial cells, systemic inflammation and oxidative stress could explain vascular alterations in these patients. We aimed at noninvasely evaluating macro- and microvascular dysfunction in cystic fibrosis adults without cardiovascular risk factors. Twenty-twoadults affected by cystic fibrosis and 24 healthy volunteers matched for age and sex were enrolled. None had known cardiovascular risk factors. All people underwent blood pressure measurement, microvascular function assessment by EndoPAT-2000 device (calculating RH-PAT index) and macrovascular evaluation by pulse wave velocity (PWV). RH-PAT index was significantly lower in patients than in controls (1.74±0.59 vs 2.33±0.34; p<0.001). Thirteen patients of 22 had a value inferior to the threshold of 1.67 (59.1%), while no controls had (p<0.001). Carotid-femoral PWV did not differ between the two groups (5.2±1.5 m/s vs 5.4±1.1; p=0.9), while brachial-ankle one did (11.0±2.2 m/s vs 10.1±0.8 m/s; p=0.04).Adults patients affected by cystic fibrosis show peripheral endothelial dysfunction, which is the first alteration in atherosclerotic phenomenon. Moreover, arterial stiffness measured by PWV unclearly seems to differ respect of healthy people, perhaps because PWV alterations are typical of above 50 years old people. It is unclear what prognostic role of future developing of atherosclerotic disease these findings could be, but it seems evident that cystic fibrosis directly affects cardiovascular system itself.

Abstract
OBJECTIVE The objective of this paper is to analyse whether digital capillary morphology, analysed by nailfold videocapillaroscopy (NVC), and the number of circulating CD3 + CD31 + CXCR4 + lymphocytes (angiogenic T cells) could be markers of endothelial dysfunction (ED) in systemic lupus erythematosus (SLE) without cardiovascular disease (CVD) and CV risk factors. METHODS Nineteen consecutive SLE patients, according to Systemic Lupus International Collaborating Clinics Classification Criteria, with a disease duration less than five years, low disease activity, without CVD and CV risk factors (diabetes, chronic renal disease, uncontrolled systemic arterial hypertension, smoking, hypercholesterolemia, obesity), statin or beta-blocker use were enrolled. Each patient and sex- and age-matched healthy control (HC) underwent Doppler echocardiogram, an endothelial function study by peripheral arterial tonometry technique, NVC and peripheral blood immunophenotyping. RESULTS SLE ED+ more frequently showed NVC abnormalities compared with HCs ( p < 0.0001) in terms of minor alterations ( p = 0.017), lower capillary numbers ( p = 0.0035) and major alterations. SLE ED + showed a higher rate of CD3 + CD31 + CXCR4 + lymphocytes compared with SLE ED- and with HCs. NVC + SLE showed a significantly reduced rate of total CD3 + cells, but a higher rate and absolute number of CD3 + CD31 + CXCR4 + , compared with NVC- SLE. CONCLUSION NVC alterations are frequent in SLE without any CV risk factors and CVD. They are associated with ED and increased circulating CD3 + CD31 + CXCR4 + lymphocytes. These findings demonstrate a clear microvascular perturbation in patients with short disease duration, low disease activity and no CV risk factors.

Abstract
BACKGROUND Coronary artery bypass grafting (CABG) remains the standard of care for patients with coronary artery disease (CAD). Debate exists concerning several factors, which include percutaneous coronary intervention (PCI) vs. CABG, single vs. bilateral mammary artery grafts, radial artery vs. saphenous vein grafts, right internal mammary artery vs. radial artery grafts, endoscopic vs. open vein-graft harvesting, and on-pump vs. off- pump surgery. Moreover, challenging is the management of diabetic patients with CAD undergoing CABG. This review reports current indications, practice patterns, and outcomes of CABG. METHODS Randomized controlled trials comparing CABG to other therapeutical strategies for CAD were searched through MEDLINE, EMBASE, Cochrane databases, and proceedings of international meetings. RESULTS Large multicenter randomized and observational studies (SYNTAX, BEST, PRECOMBAT, ASCERT) have reported excellent outcomes in CABG patients, with always fewer rates of operative mortality and major morbidity, than PCI. The 10-year follow-up of ARTS II trial showed no difference between single and bilateral mammary artery. BARI 2D, MASS II, CARDia, FREEDOM trials showed that CABG is the best choice for diabetic patients. CONCLUSION CABG still represents one of the most widespread major surgeries, with well-known benefits on symptoms and prognosis in patients with CAD. However, further studies and follow-up data are needed to validate these evidences.

Inappropriate left ventricular mass after preeclampsia: another piece of the puzzle Inappropriate LVM and PE. Hypertens Res 2018; 42:522-529.

Abstract
Excessive left ventricular (LV) mass (LVM) increase results in inefficient LV work with high energy waste and a negative prognostic effect. We aimed to investigate the presence of inappropriate LVM and to calculate the myocardial mechanoenergetic efficiency index (MEEi) in asymptomatic women with a history of early-onset (EO) or late-onset (LO) pre-eclampsia (PE). Among all women diagnosed with PE in the years 2009-2013, after applying inclusion/exclusion criteria and cost-effectiveness analysis, we randomly selected thirty women who experienced EO-PE, thirty with a previous LO-PE and thirty healthy controls to undergo echocardiography from 6 months to 4 years after delivery. Data regarding gestational age (GA) and mean uterine artery (UtA) pulsatility index (PI) at PE onset were collected from medical records. All women were free from cardiovascular risk factors. LVM excess was calculated as the ratio between observed LVM and predicted LVM (by sex, stroke work and height), while MEEi was calculated as the ratio between stroke work and "double product" (to approximate energy consumption), indexed to LVM. Concentric remodeling was present in 60% of EO-PE and 53% of LO-PE. LVM excess was significantly more often present in the EO-PE group than in the control group. LVM was inappropriate in 52% of EO-PE and 17% of LO-PE. MEEi showed a tendency towards lower values in the EO-PE group. Multivariate regression analysis showed that both LVM excess and MEEi were independently associated with lower GA and higher mean UtA PI at PE onset. Inappropriate LVM with a tendency towards reduced MEEi in the first 4 years after delivery may partially explain the elevated cardiovascular risk in former pre-eclamptic women compared to the general population.

Abstract
OBJECTIVES Myocardial fibrosis is associated with adverse clinical outcome in adults. Our aim was to investigate using echocardiographic calibrated integrated backscatter (cIBS) the presence of myocardial and/or aortic fibrosis in asymptomatic women with a history of early-onset (EO) or late-onset (LO) pre-eclampsia (PE). METHODS Thirty non-pregnant women whose most recent pregnancy was complicated by EO-PE, 30 with previous LO-PE pregnancy and 30 controls who had experienced only uncomplicated pregnancy previously were selected retrospectively from our electronic database and recalled between 6 months and 4 years after delivery. Data regarding gestational age (GA) and mean uterine artery (UtA) pulsatility index (PI) at diagnosis of PE were collected from their medical records. The women underwent cardiovascular assessment, during which the presence of fibrosis was investigated, by means of cIBS, at the basal interventricular septum (cIBSIVS ), the basal posterior wall (cIBSPW ) and the anterior wall of the ascending aorta, 3 cm above the valve (cIBSAO ). These findings were compared between the three patient groups. RESULTS Using cIBS imaging, we found significant left ventricular (LV) fibrosis in women with a history of EO-PE compared with those with previous LO-PE pregnancy and controls (intergroup ANOVA P < 0.001 for cIBSIVS and P = 0.005 for cIBSPW ), whereas aortic fibrosis did not differ significantly among cases and controls. Stepwise multivariate regression analysis showed that LV fibrosis was associated independently with lower GA and higher mean UtA-PI at diagnosis of PE, while cIBSAO correlated with aortic diameters, stiffness and ventricular-arterial coupling. CONCLUSIONS Women with a history of EO-PE show LV fibrosis in the short-medium term after delivery compared with women with previous LO-PE pregnancy and controls. LV fibrosis is associated with GA and mean UtA-PI at onset of PE. Larger studies using cardiac magnetic resonance imaging are needed to validate and confirm our findings. Copyright © 2017 ISUOG.

Abstract
Psoriasis is a systemic inflammatory disease with a great prevalence in general population. The inappropriate activation of the cellular immune system has been hypothesized to be an independent cardiovascular risk factor, given the higher incidence of cardiovascular disorders in psoriatic patients. Echocardiographic abnormalities have been demonstrated too: the aim of our study was to evaluate the presence of preclinical cardiac dysfunction in a cohort of psoriatic patients without cardiovascular risk factors. We enrolled 52 patients with the diagnosis of chronic plaque psoriasis, compared with a control group not affected by any relevant systemic diseases and inflammatory disorders. In all patients and control group, echocardiographic conventional and tissue Doppler (TDI) studies were conducted. The analysis of echocardiographic parameters revealed normal dimension, mass and systolic function of the left ventricle. Left ventricular diastolic dysfunction was found in 36.5% patients in the psoriasis group versus 0% in control group, and significant reduction of the E/A ratio was found also for the right ventricle. A significant increase of mitral regurgitation has been found in psoriatic patients (p=0.005). The early recognition of cardiovascular pre-clinic disease in psoriatic patients may guide a strict follow up and an early treatment, potentially improving cardiovascular prognosis.

Abstract
OBJECTIVE The objective of this study was to longitudinally evaluate maternal echocardiographic findings in uncomplicated twin gestations according to chorionicity. METHODS Healthy women with twin pregnancy were assessed with transthoracic echocardiography across the first, second, and third trimesters. Cardiac findings were compared within each group and between monochorionic (MC) and dicho-rionic (DC) pregnancies. RESULTS Overall, 19 MC and 48 DC uncomplicated twin pregnancies were included. In the MC group, no significant maternal haemodynamic changes were documented across gestation, with the exception of a decrease in ejection fraction. Compared to DC pregnancies, in the MC set lower cardiac output (second and third trimester, p = 0.001 and p = 0.006, respectively) and higher total vascular resistance (first trimester, p = 0.032) were observed. Regarding the diastolic function in MC twins, significantly higher values were observed for mitral E/A ratio (third trimester, p = 0.014), septal mitral E1/A1 ratio (third trimester, p = 0.030), lateral mitral E1 (second and third trimester, p = 0.014 and p = 0.029, respectively), and E1/A1 ratio (third trimester, p = 0.006). CONCLUSIONS Maternal cardiac adaptation in twin pregnancy seems to differ significantly according to chorionicity. In particular, in MC pregnancies the impairment of diastolic function is less pronounced, presumably due to the lower circulating volume.

Abstract
BACKGROUND Nowadays there is an increased interest in the role of aortic stiffness in the pathophysiology of heart failure (HF), as it is a major determinant of left ventricular (LV) performance. We aimed at assessing the predictive value of the aortic stiffness parameters, measured by echocardiography, in patients affected by nonischaemic dilated cardiomyopathy (DCM) regarding three end-points: death, HF rehospitalization, combined death or HF rehospitalization in a long-term follow-up. MATERIALS AND METHODS A total of 202 patients affected by nonischaemic DCM underwent an outpatient examination by echocardiography and blood pressure check at the brachial artery, in order to calculate aortic elastic properties (ie, compliance, distensibility, stiffness index, Peterson's elastic modulus, M-mode strain). ROC curves, Kaplan-Meier curves and multivariable Cox regressions (correcting for age, LV ejection fraction (LVEF), atrial fibrillation, cardiac resynchronization therapy (CRT)) were run to assess the predictive ability of aortic elastic properties against the 3 end-points. RESULTS Mean follow-up was 9.83 ± 2.80 years. 24.8% of patients died, while 34.7% were rehospitalized for HF cause and 44.6% experienced the combined end-point. LVEF did not correlate with aortic elastic properties. ROC curves and Kaplan-Meier curves were elaborated. Aortic stiffness did not predict death in our cohort. Otherwise, all aortic elastic properties predicted HF rehospitalization and combined death or HF rehospitalization, after correcting for age, LVEF, atrial fibrillation, CRT. CONCLUSIONS Elastic properties of the ascending aorta measured by echocardiography in patients with nonischaemic DCM predict long-term HF rehospitalization and combined death or HF rehospitalization, also after correcting for the confounding factors.

Abstract
BACKGROUND Low relative lymphocyte count is an important prognostic marker in acute heart failure (AHF); however, it could be influenced by other abnormalities in white cells count. Our purpose is to evaluate if low absolute lymphocyte count (ALC) is an independent predictor of events in patients with AHF. METHODS In a retrospective analysis, we included 309 patients with AHF, divided into two groups according to the median value of ALC at admission (1410 cells/μl). The primary end point was all-cause mortality or urgent heart transplantation within 1 year. RESULTS Patients with low ALC were older and had more comorbidity, namely atrial fibrillation, chronic kidney disease, chronic obstructive pulmonary disease and anemia. Low ALC was associated with higher all-cause mortality or urgent heart transplantation at 1 year (24.3 vs 13.0%; P = 0.012). In a multivariable model, the independent predictors of mortality at 1 year were ALC 1410 cells/μl or less at admission [hazard ratio 2.04; CI (confidence interval) 95% (1.06-3.95); P = 0.033], age [hazard ratio 1.08; CI 95% (1.04-1.12); P < 0.001], baseline serum creatinine [hazard ratio 1.25; CI 95% (1.05-1.50); P = 0.012] and baseline serum Na [hazard ratio 0.91; CI 95% (0.85-0.98); P = 0.013]. CONCLUSION Low ALC in patients with AHF is associated with higher in-hospital mortality during the hospitalization and is an independent predictor of long-term mortality.

Abstract
The case deals with an anaphylactoid reaction to intravenous ampicillin/sulbactam resulting in cardiogenic syncope and myocardial damage. Symptoms and ECG modifications promptly disappeared after corticosteroids administration. The Kounis syndrome is an acute coronary syndrome, including coronary spasm, acute myocardial infarction and stent thrombosis, resulting from an anaphylactic or anaphylactoid or allergic or hypersensitivity insult. First described in 1991, it can be caused by a lot of substances, particularly antibiotics. The management should be directed to both the allergic reaction and the myocardial damage. The Kounis syndrome is a not rare disease that every physician should know because of the wideness of triggers and the possible fatal evolution if not promptly recognized.

Effects of ivabradine on endothelial function, aortic properties and ventricular-arterial coupling in chronic systolic heart failure patients. Cardiovasc Ther 2018; 36:e12323.

Abstract
AIM Heart rate (HR) is an important prognostic factor in patients affected by chronic heart failure (CHF); ivabradine has been demonstrated to significantly reduce nonfatal myocardial infarction and hospitalization rate for acute heart failure and to improve left ventricular (LV) reverse remodeling, quality of life, exercise capacity, and arterial elastance (Ea) in these patients. We aimed at evaluating the short-term effects of ivabradine on ventricular-arterial coupling (VAC), aortic stiffness, and endothelial function in stable patients with CHF. METHODS We evaluated 30 consecutive CHF patients (LVEF≤ 35%, NYHA class II) with sinus rhythm and HR ≥ 70 bpm on optimized pharmacological therapy. All of them underwent both transthoracic echocardiogram to assess aortic elastic properties (aortic distensibility, AD; aortic stiffness index, ASI; systolic aortic strain, SAS) and VAC, and peripheral arterial tonometry to measure endothelial function. Therapy with ivabradine 5 mg bid was added and each patient was evaluated with the same examinations after 4 months. RESULTS At the baseline, 73% of patients had impaired VAC and 63% endothelial dysfunction. After 4 months, there was a significant improvement in the VAC value (ΔVAC -0.10 ± 0.18, P = .021), mainly linked to Ea (ΔEa -0.40 ± 0.23 mm Hg/mL; P = .003). All the parameters of aortic elasticity underwent significant improvement (ΔAD 1.82 ± 1.43 cm² × dyn- ¹, P = .004; ΔASI -4.73 ± 6.07, P = .033; ΔSAS -7.98 ± 4.37%, P = .003). Lastly, we also noted a significant improvement of endothelial function (Δ RHI 0.35 ± 0.35; P < .001). At follow-up 40% of patients had impaired VAC (P = .018) and 33% endothelial dysfunction (P = .038). CONCLUSION In patients with CHF adding ivabradine on top to the standard optimized medical therapy, when indicated, seems to improve endothelial function, aortic properties, and VAC.

Abstract
BACKGROUND Hypertension is strongly related to arterial stiffness in a cause-effect fashion. Diabetes mellitus is also thought to determine vascular damage, mostly by means of advanced glycosylation end-products (AGEs). Aim of our study was to study the role of type 2 diabetes mellitus (T2DM) as regard ascending aortic elastic properties in hypertensive patients. METHODS We prospectively enrolled outpatients with hypertension (n = 99) and type 2 diabetes mellitus plus hypertension (n = 42) without cardiovascular events. They underwent a transthoracic echocardiography to measure aortic diameters, aortic elastic properties (ie, compliance, distensibility, stiffness index, Peterson's elastic modulus, pulse wave velocity, M-mode strain), tissue Doppler imaging (TDI) to calculate diastolic (E' and A') and systolic (S') velocities, and tissue strain. Multivariable analysis was run to assess the association between T2DM and these variables after correcting for possible confounders (age, sex, body mass index [BMI], dyslipidemia). RESULTS The two groups did not differ as regards age, sex, BMI, and blood pressure. However, T2DM patients were more likely to be dyslipidemic (43% vs 71%, P = .003). Aortic diameters were similar in the two groups, but the aortic elastic properties significantly more impaired in T2DM group. At multivariable analysis, stiffness index, Peterson's elastic modulus, the TDI waves, and the tissue strain remained associated with the co-presence of T2DM and hypertension. CONCLUSION Our data suggest that people suffering from both T2DM and hypertension have more impaired aortic elastic properties than those hypertensive alone. Considering the prognostic role of aortic stiffness, these patients may benefit from a closer follow-up.

Abstract
AIMS Obstructive sleep apnoea-hypopnoea (OSAH) is a prevalent condition characterized by repetitive pharyngeal collapse during sleep, leading to hypoxemia, hypercapnia, and persistent inspiratory efforts against an occluded airway until arousal. Several studies demonstrated that OSAH exerts acute and chronic effects on the cardiovascular system. Thus, although being a respiratory problem, the most important consequences of OSAH are cardiovascular, among which there are arrhythmias. The purpose of this review is to systematically analyse what has been recently published about the relationship between OSAH and every cardiac arrhythmia separately. METHODS We searched Pubmed, Scopus, Web of Science and Cochrane Collaboration databases for 'OSAHS arrhythmias', 'OSAH arrhythmias' and 'OSA arrhythmias'. We analyse 1298 articles and meta-analyses, excluding already edited reviews. RESULTS Arrhythmias, especially of ventricular origin, are frequent in OSAH. Ventricular premature beats, couplets and ventricular tachycardia runs are even more frequent in patients suffering from heart failure. They may be due to left heart remodelling, overwork and ischaemia and can explain at least some sudden deaths occurring between midnight and 6 a.m. Sinus pauses and atrioventricular blocks are increased according to the severity of the disturbance and may be reduced by continuous positive airway pressure therapy, preventing pace-maker implantation. Finally, atrial fibrillation, resistance against antiarrhythmic drugs and recurrences after surgical procedures are strongly related to OSAH. CONCLUSION Arrhythmias are frequent in OSAH. Treatment of OSAH may reduce some of them. An implantable cardioverter-defibrillator and continuous positive airway pressure should be considered in some patients.

Abstract
OBJECTIVES To assess endothelial function and arterial stiffness in women with a previous pregnancy complicated by pre-eclampsia (PE) with hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome, and to compare these findings to those in women with previous PE but no HELLP and to those in controls with previous uncomplicated pregnancy, in order to investigate the influence of HELLP syndrome on subsequent cardiovascular impairment. METHODS In this prospective single-center case-control study, we performed peripheral arterial tonometry (PAT) (using the EndoPAT method) and pulse-wave velocity (PWV) assessment in 109 women who had had a singleton pregnancy complicated by PE with (n = 49) or without (n = 60) HELLP syndrome, as well as in 60 controls with previous uncomplicated pregnancy, between 6 months and 4 years after delivery. The following EndoPAT and PWV indices were compared between groups: reactive hyperemia index (RHI), as an indication of endothelial function, and peripheral and aortic heart-rate-corrected augmentation indices (AIx) standardized for a heart rate of 75 bpm (AIx@75) and carotid-femoral pulse-wave velocity (cfPWV), as indications of arterial stiffness. RESULTS PAT and arterial stiffness indices were significantly different between PE cases, with or without previous HELLP, and controls, except for carotid-femoral PWV. There were no significant differences among PE groups: women who had experienced HELLP and those with a history of PE without HELLP showed similar rates of RHI ≤ 1.67 (28.6% vs 18.3%, P = 0.254) and RHI ≤ 2.00 (61.2% vs 41.7%, P = 0.055), peripheral AIx@75 ≥ 17% (38.8% vs 30.0%, P = 0.417), aortic AIx@75 ≥ 35% (29.2% vs 20.0%, P = 0.461) and cfPWV × 0.8 > 9.6 m/s, which occurred in only three women, all in the group without previous HELLP (0% vs 5.0%, P = 0.251). On multivariate regression analysis, HELLP syndrome, intrauterine growth restriction (IUGR) and early-onset PE independently predicted endothelial dysfunction at 6 months to 4 years postpartum, after correcting for uterine artery pulsatility index, birth-weight percentile, and maternal blood pressure, age and body mass index. Women with both previous HELLP and early-onset IUGR had a significantly higher prevalence of endothelial dysfunction (P = 0.001). CONCLUSION Similar vascular abnormalities were found in women previously affected by HELLP syndrome and those with previous PE without HELLP. However, a history of HELLP syndrome, IUGR and early-onset PE seems to identify a subgroup of women with a higher risk for future development of endothelial dysfunction. Copyright © 2016 ISUOG.

Abstract
OBJECTIVE To evaluate maternal hemodynamics in asymptomatic women with a previous pregnancy affected by hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome and compare the findings to those of women with previous pre-eclampsia (PE) and controls with a previous uncomplicated pregnancy. METHODS Women with a history of PE (n = 60) or HELLP syndrome (n = 49) and matched healthy controls (n = 60) underwent echocardiography at 6 months to 4 years after delivery, recording left ventricular (LV) dimensions, ejection fraction (LVEF) and mass, right ventricular (RV) tricuspid annular plane systolic excursion and fractional area change (FAC). Diastolic filling (E/A and E/E' ratios) and tissue Doppler imaging were evaluated for both ventricles and the myocardial performance index was calculated. RESULTS Only women with previous HELLP syndrome showed significant LV concentric hypertrophy (20.4%). However, in both HELLP and PE groups, LV concentric remodeling (46.9% and 46.7%, respectively), diastolic dysfunction (expressed as altered E/A and E/E' ratios) and reduced LVEF (14.3% and 21.7%, respectively) were documented. RV variables did not differ significantly between cases and controls, except for FAC and E/E' ratio, which were slightly impaired in women with previous HELLP syndrome compared to those with previous PE (16.3% vs 10.0%, P = 0.04; 14.3% vs 3.3%, P = 0.03, respectively). CONCLUSIONS The significant overlap of echocardiographic features in women with previous PE and HELLP syndrome suggests that these two conditions share the same pathophysiology. However, HELLP syndrome may lead to more severe cardiovascular remodeling in the short to medium term after delivery. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVES To investigate cardiovascular (CV) performance status several years after early-onset (EO) or late-onset (LO) pre-eclampsia (PE), using echocardiography to assess myocardial strain and left ventricular (LV) torsional mechanics and ventricular-arterial coupling (VAC). METHODS Thirty non-pregnant women with a previous singleton pregnancy complicated by EO-PE, 30 who had experienced LO-PE and 30 controls underwent echocardiography with two-dimensional (2D) speckle tracking between 6 months and 4 years after delivery and their findings were compared. All women were free from CV risk factors. VAC was defined as the ratio between aortic elastance (Ea) and LV end-systolic elastance (Ees). RESULTS Women in the EO-PE group showed a persistent subclinical impairment in LV systole and a slight alteration in right ventricular function, with reductions in LV 2D strain (circumferential, radial and longitudinal) and right ventricular 2D strain and impairment of LV torsional mechanics, when compared both with women in the LO-PE group and with healthy controls. Although VAC was within the normal range in the whole study cohort, its individual components Ea and Ees were significantly altered more often in the EO-PE group than in both the LO-PE group and controls. All parameters investigated (except right ventricular 2D strain) were associated independently with gestational age at the time of diagnosis of PE. CONCLUSIONS Women with a history of EO-PE are more likely to have subclinical impairment of systolic biventricular function than are those with a history of LO-PE and controls. The components of VAC (Ea and Ees) show subclinical alterations which are more significant in women with a history of EO-PE than in those with a history of LO-PE and controls, although VAC itself is maintained. Our study supports the use of closer CV monitoring in previously pre-eclamptic women, particularly those in whom PE was preterm. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVES Pre-eclampsia (PE) is associated with an increased cardiovascular risk later in life. The persistence of endothelial dysfunction after delivery may represent the link between PE and cardiovascular disease. We aimed to evaluate endothelial function and arterial stiffness after delivery of pregnancy complicated by early-onset (EO) or late-onset (LO) PE and their correlation with gestational age and mean uterine artery pulsatility index at PE diagnosis and birth-weight percentile. METHODS The study included 30 women with previous EO-PE, 30 with previous LO-PE and 30 controls with no previous PE. Participants were examined at between 6 months and 4 years after delivery. All included women were free from cardiovascular risk factors and drugs. Data on demographic and clinical characteristics during pregnancy were collected retrospectively from obstetrical charts. Endothelial function and arterial stiffness were assessed by peripheral arterial tonometry and pulse-wave analysis. RESULTS All vascular parameters were significantly different, indicating circulatory impairment, in women with previous EO-PE. Women with previous LO-PE had higher vascular rigidity than did controls and all had normal values of reactive hyperemia index, although they were significantly lower when compared with those of controls. On multivariate analysis, gestational age and mean uterine artery pulsatility index at the time of PE diagnosis, and birth-weight percentile were all statistically related to the vascular indices studied, after correcting for confounding parameters. CONCLUSIONS Women with previous pregnancy complicated by PE, in particular those with early-onset disease, showed persistent microcirculatory dysfunction, as suggested by a significant reduction in reactive hyperemia index value, and increased arterial stiffness.

Abstract
Cardiac resynchronization therapy (CRT) is an important tool for the treatment of patients with chronic heart failure, as it can correct the heterogeneity of regional left ventricular mechanical contraction, known as dyssynchrony. Although this therapy is strongly indicated in patients with both heart failure with left ventricular systolic dysfunction and wide Q-, R- and S-waves (QRS) on electrocardiogram, about one-third of these patients are non-responders. Since the degree of mechanical dyssynchrony can vary greatly, it is interesting to quantify dyssynchrony by means of imaging methods, such as echocardiography, which might be able to lead to a better selection of CRT candidates. This article will review the role of old and new echocardiographic techniques to predict CRT response.

Abstract
Heart failure (HF) is the main cause of mortality and morbidity in Western countries. Although evidence-based treatments have substantially improved outcomes, prognosis remains poor with high costs for health care systems. In patients with HF, poor dietary behaviors are associated with unsatisfactory quality of life and adverse outcome. The HF guidelines have not recommended a specific nutritional strategy. Despite the role of micronutrient deficiency, it has been extensively studied, and data about the efficacy of supplementation therapy in HF are not supported by large randomized trials and there is limited evidence regarding the outcomes. The aim of the present review is to analyze the state-of-the-art of nutritional deficiencies in HF, focusing on the physiological role and the prognostic impact of micronutrient supplementation.

Abstract
<p><strong>Aim</strong>. Rheumatoid arthritis (RA) shows a high risk for cardiovascular disease, including heart failure. Although TNF-α has been implicated in the pathogenesis of myocardial remodelling, TNF-α inhibition did not show any efficacy in patients with advanced heart failure and should be contraindicated in RA with cardiac complications. We aimed to assess global left ventricular (LV) systolic function using global longitudinal strain (GLS) as a measure of myocardial deformation, in a group of RA patients before and during anti-TNF-α treatment. <strong>Methods</strong>. 13 patients (female:male 7:6) affected by RA were prospectively followed for one year during anti TNF-α treatment. Every subject underwent echocardiography before starting anti-TNF-α drugs and after one year of treatment, to evaluate LV ejection fraction (EF), telediastolic diameter, telediastolic volume and global longitudinal strain (GLS) that was calculated using 2D speckle tracking as the mean GLS from three standard apical views (2, 3 and 4 -chambers). The patients showed a mean age of 43 years at RA onset (SD: 13) and a mean follow-up of 7.3 years (SD: 4.8). Steroid and methotrexate were used in 84.6% and 100%, respectively, in association with etanercept (6 cases), adalimumab (4 cases) and infliximab (3 cases). <strong>Results</strong>. Patients globally showed a normal EF before and after one year of treatment (mean: 65% and 65.7%, respectively). GLS did not differ before or after anti-TNF-α treatment (mean: -15.8% and -16.7%, respectively). <strong>Conclusion</strong>. Anti-TNF-α treatment did not significantly modify myocardial contractility after 12 months.</p><p> </p><p> </p>

Abstract
AIM Red cell distribution width (RDW) is a measure of anisocytosis. Higher values are robustly associated to adverse outcome in several conditions, including chronic heart failure (HF). The present study aimed to compared its prognostic role with that of echocardiographic parameters in this kind of patients. METHODS 32 stable and optimally treated chronic HF patients were enrolled. We excluded subjects suffering from valvular diseases or atrial fibrillation. They underwent blood sampling and echocardiographic examination. The primary endpoint of the study was cardiovascular death and/or HF hospitalization in the first year after enrolment. RESULTS 49 patients reached the primary endpoint. RDW best cut-off at ROC curve was 14.45%. Univariate analysis associated mitral regurgitation grade, left ventricular ejection fraction (LVEF), posterior wall thickness (PWT), LV mass index, and RDW>14.45% to the primary endpoint. Multivariate regression analysis showed that LVEF, PWT, and RDW>14.45% predict the primary endpoint. Area under ROC curve was 0.808 for LVEF, 0.762 for NYHA class, and 0.761 for RDW. CONCLUSION In chronic HF patients RDW is a better predictor of adverse outcome than several echocardiographic parameters associated to outcome itself (LV mass index, mitral regurgitation grade), predicts prognosis even adjusting for those parameters, age and NYHA class, and is associated to several echocardiographic measurements. In conclusion, RDW can expand our tool bag in order to better follow-up these patients.

Abstract
BACKGROUND Cardiovascular manifestations of inflammatory bowel disease (IBD) are considered rare. The aim of the present study was to assess cardiac structure and function by means of traditional Doppler echocardiography and tissue Doppler imaging in order to better appreciate myocardial subclinical alterations and their future implications for these kind of patients. METHODS Twenty-seven patients affected by Crohn's disease (CD) and 43 suffering from ulcerative colitis (UC) were enrolled. They were selected without cardiovascular diseases nor risk factors. They were compared with 24 healthy subjects matched for sex and age. Everyone underwent transthoracic echocardiography. RESULTS IBD patients had larger left atrial anterior-posterior dimension (34±7 vs. 31±2 mm; P=0.001) and volume (46±7 vs. 41±6; P=0.002), reduced left ventricular (LV) ejection fraction (59±6 vs. 63±5%; P=0.006) and higher pulmonary artery systolic pressure (26±6 vs. 22±2 mmHg; P<0.001) than healthy volunteers. Moreover, LV diastolic function was slightly altered in patients in respect of controls. Atrioventricular valve regurgitation was prevalent in IBD. Finally, we found that 18 (25.7%) patients had mitral valve prolapse, 35 (50.0%) mitral valve leaflets thickening and 3 (4.3%) pericardial effusion. We did not find differences in echocardiographic parameters between CD and UC. CONCLUSIONS Our study suggests that subclinical cardiac involvement is frequent among IBD patients. The underlying mechanisms require further evaluation, but might be due to a systemic increase in cytokines and profibrotic factors.

Abstract
BACKGROUND Many studies proved the prognostic importance of aortic stiffness as an independent predictor of cardiovascular morbidity and all-cause mortality. The decrease of arterial compliance has a high prevalence in patients with heart failure and affects both hemodynamics and prognosis. Aortic stiffness is partially caused by excessive activation of the renin-angiotensin-aldosterone system. Spironolactone, a mineralcorticoid receptor antagonist (MRA), has been shown to decrease aortic stiffness and fibrosis in experimental models. However, there are few studies that describe the effects of MRA on aortic stiffness in patients with nonischemic dilated cardiomyopathy. AIMS To evaluate the effect of spironolactone on aortic stiffness in patients with nonischemic dilated cardiomyopathy. MATERIALS AND METHODS We randomized (1 : 1) 102 patients with nonischemic dilated cardiomyopathy with New York Heart Association class I-II to receive spironolactone 25 mg/day (up to 100 mg/day) or placebo, in addition to recommended therapy. Aortic stiffness index, aortic strain, aortic distensibility and aortic dimensions were assessed at baseline and after 6 months. All measures were obtained with echocardiography M-mode at 3 cm above the aortic valve on parasternal long axis view and simultaneous brachial arterial pressure with sphygmomanometer. RESULTS Ascending aorta diameters, aortic stiffness index, aortic distensibility and aortic strain were similar at randomization in the two groups. After 6 months of therapy in the treated group, we found a reduction of aortic stiffness index (7.2 ± 3.5 versus 9.6 ± 4.8 mmHg; P = 0.03) and an increase of aortic distensibility (3.77 ± 1.0 versus 2.92 ± 0.55 mmHg; P = 0.01) and systolic aortic strain (10.0 ± 5.0 versus 8.0% ± 2.1%; P = 0.01). There were no difference in systolic arterial pressure, diastolic arterial pressure and differential pressure in the two groups. CONCLUSION Therapy with spironolactone is effective in reducing aortic stiffness in patients with nonischemic dilated cardiomyopathy. This effect could improve hemodynamics supporting the use of MRAs in patients with low New York Heart Association class (I-II).

Abstract
Tricuspid regurgitation (TR) is a common Doppler echocardiographic finding resulting from either intrinsic valve abnormalities or functional malcoaptation of structurally normal valves. TR caused by flail leaflets is most often post-traumatic, is caused by endocarditis or is a consequence of a myxomatously degenerated valve. The clinical presentation is severe and is characterized by excess mortality and high morbidity. Flail leaflets are reliably diagnosed using 2-dimensional and 3-dimensional echocardiography.

Abstract
Acute heart failure (AHF) represents a major healthcare burden with a high risk of in-hospital and post-discharge mortality, which remained almost unchanged in the last few decades, underscoring the need of new treatments. Relaxin is a naturally occurring human peptide initially identified as a reproductive hormone and has been shown to play a key role in the maternal hemodynamic and renal adjustments that accommodate pregnancy. Recently, the new molecule serelaxin, a recombinant form of the naturally occurring hormone relaxin has been studied in patients hospitalized for AHF. In addition to vasodilation, serelaxin has anti-oxidative, anti-inflammatory and connective tissue regulating properties. In preclinical studies, it reduced both systemic and renal vascular resistance and, in the clinical trials Pre-RELAX-AHF and RELAX-AHF, it improved dyspnea and signs of congestion. In addition, serelaxin was associated with a reduction of 180-day mortality. The aim of this review is to summarize the pharmacological properties of serelaxin and the results of the preclinical and clinical studies.

Elastic properties of ascending aorta in women with previous pregnancy complicated by early- or late-onset pre-eclampsia. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2016; 47:316-323.

Abstract
OBJECTIVES To evaluate the elastic properties of the ascending aorta in women with a previous pregnancy complicated by early-onset (EO) or late-onset (LO) pre-eclampsia (PE) and the correlation with gestational age (GA), systolic/diastolic blood pressure (SBP/DBP) and mean uterine artery pulsatility index (UtA-PI) at diagnosis of the disease as well as with birth weight of the neonate. METHODS Thirty women who had a previous pregnancy complicated by EO-PE, 30 with a previous pregnancy complicated by LO-PE and 30 normal controls were selected retrospectively from our electronic database and then recalled for assessment from 6 months to 4 years after delivery. Data regarding GA, SBP/DBP and mean UtA-PI at the diagnosis of PE were obtained from medical records. At our assessment, aortic M-mode and tissue Doppler imaging (TDI) parameters were measured. Aortic diameters were assessed at end-diastole at four levels: Valsalva sinuses, sinotubular junction, tubular tract and aortic arch. Aortic compliance, distensibility, stiffness index (SI), Peterson's elastic modulus (EM), pulse-wave velocity and M-mode strain were calculated using standard formulae. Aortic expansion velocity, early and late diastolic retraction velocities and peak systolic tissue strain (TDI-ϵ) were determined. RESULTS Aortic diameters at the four levels were significantly greater in both EO-PE and LO-PE groups than in controls. Aortic compliance and distensibility and TDI-ϵ were lower in EO-PE than in LO-PE (P = 0.001, P = 0.002 and P = 0.011, respectively) and controls (P = 0.037, P = 0.044 and P = 0.013, respectively). SI and EM were higher in EO-PE than in LO-PE (P = 0.001 and P < 0.001, respectively) and than in controls (P = 0.035 and P = 0.036, respectively). Multivariate analysis showed GA, DBP and UtA-PI at diagnosis of PE to be independent predictors of aortic elastic properties. CONCLUSIONS Elastic properties of the ascending aorta were altered in women with a previous pregnancy complicated by EO-PE, but not in those with LO-PE. Copyright © 2015 ISUOG.

Abstract
INTRODUCTION Tako-Tsubo cardiomyopathy (TTC) is an acute cardiomyopathy mimicking acute myocardial infarction. The aim of our study was to define clinical and instrumental features of an Italian population of patients with TTC and to report their short and mid-term outcome. METHODS We retrospectively evaluated 42 patients admitted to our Department with diagnosis of TTC (100% women, age 67 ± 11 years) using Mayo Clinic-modified criteria. In this population, we analyzed the stressful event (if present), the clinical presentation, the ECG and echocardiogram at admission and the markers of myocardial cytonecrosis, such as troponin I, at admission and during the hospitalization. All the patients have been clinically evaluated after 6 months and 1 year of follow-up. RESULTS In this population, a stressful event before TTC has been detected in 59% of patients. The most common clinical presentation was chest pain (81%) and the major sign was dyspnea (17%). ECG showed negative T waves and ST elevation, respectively, in 45 and 38%. Only 10% had a ST depression and 7% developed a newly acquired complete left bundle branch block. All of these abnormalities disappeared within 1.8 ± 0.9 days. The mean ejection fraction at admission was 35 ± 7% associated with apical (40%), mid-apical (56%) and mid-ventricular (4%) wall motion abnormalities. The recovery of these abnormalities occurred within 10 ± 3 days. At 6-month and 1-year follow-up, no patients had TTC recurrence, and 10 patients at 6 months and 20 patients at 1 year were re-hospitalized for a non-cardiac cause. CONCLUSION Our data describe the characteristics of TTC in a small Italian population, which are similarly described in Japanese and North American people. TTC was related to a very low mortality, both in the short and mid term, but the risk of acute heart failure in the acute phase could not be neglected.
