Introduction: This study aims to assess the changes in cardiovascular remodeling attributable to bodyweight gain in a middle-aged abdominal obesity cohort. A remodeling worsening might explain the increase in cardiovascular risk associated with a dynamic of weight gain.Methods: Seventy-five middle-aged subjects (56 ± 5 years, 38 women) with abdominal obesity and no known cardiovascular disease underwent MRI-based examinations at baseline and at a 6.1 ± 1.2-year follow-up to monitor cardiovascular remodeling and hemodynamic variables, most notably the effective arterial elastance (Ea). Ea is a proxy of the arterial load that must be overcome during left ventricular (LV) ejection, with increased EA resulting in concentric LV remodeling.Results: Sixteen obese subjects had significant weight gain (>7%) during follow-up (WG+), whereas the 59 other individuals did not (WG–). WG+ and WG– exhibited significant differences in the baseline to follow-up evolutions of several hemodynamic parameters, notably diastolic and mean blood pressures (for mean blood pressure, WG+: +9.3 ± 10.9 mmHg vs. WG–: +1.7 ± 11.8 mmHg, p = 0.022), heart rate (WG+: +0.6 ± 9.4 min−1 vs. −8.9 ± 11.5 min−1, p = 0.003), LV concentric remodeling index (WG: +0.08 ± 0.16 g.mL−1 vs. WG−: −0.02 ± 0.13 g.mL−1, p = 0.018) and Ea (WG+: +0.20 ± 0.28 mL mmHg−1 vs. WG−: +0.01 ± 0.30 mL mmHg−1, p = 0.021). The evolution of the LV concentric remodeling index and Ea were also strongly correlated in the overall obese population (p < 0.001, R2 = 0.31).Conclusions: A weight gain dynamic is accompanied by increases in arterial load and load-related concentric LV remodeling in an isolated abdominal obesity cohort. This remodeling could have a significant impact on cardiovascular risk.

Introduction: Obesity is linked to an adverse cardiac structural phenotype in cross-sectional studies. However, the effects of longitudinal changes in generalized and central adiposity on left ventricular (LV) remodeling are unknown. Methods: Participants without baseline cardiovascular disease or LV dysfunction in the Dallas Heart Study underwent assessment of body composition and cardiac structure by MRI at baseline and then 7 years later. Associations between change in weight and waist circumference with alterations in structure and function were assessed using multivariable linear regression. Results: The study cohort (n=1262) had a mean age of 44 years and was 43% (545 of 1262) male, 44% (556 of 1262) African-American, and 36% (460 of 1262) obese at baseline. At 7 years follow-up, 7% (85 of 1262) had >10% weight loss, 8% (108 of 1262) had 5-10% weight loss, 44% (551 of 1262) had <5% weight change, 20% (248 of 1262) had 5-10% weight gain, and 21% (270 of 1262) had >10% weight gain. Those who gained >10% weight were younger, had lower BMI and LV mass at baseline, and had greater increases in blood pressure, glucose, triglycerides, LDL cholesterol, and hs-CRP over follow-up. In multivariable models adjusted for age, sex, race, and baseline and interim development of comorbidities, 1-standard deviation increases in body weight and waist circumference over follow-up were significantly associated with higher LV mass, LV wall thickness, and concentricity; but minimally or not significantly associated with LV end-diastolic volume or ejection fraction (EF) (Table). Conclusion: Increases in generalized and central adiposity are characterized primarily by concentric remodeling, with a more modest impact on LV volume and EF. These results support the notion that the development of specific obesity patterns may impact cardiac remodeling with potential implications for the development of cardiac hypertrophy and heart failure.

Abstract BACKGROUND Total anomalous pulmonary venous connection (TAPVC) is a rare correctable congenital heart lesion. According to the modified World Health Organization classification (mWHO) of maternal cardiovascular risk, pregnant patients with successfully repaired TAPVC are at low cardiovascular risk (mWHO class I), but the risk rises to mWHO class III if left ventricular (LV) impairment and ventricular arrhythmias are present. CASE SUMMARY A 34 years old woman with corrected supracardiac TAPVC, pregnant with a spontaneous monochorionic diamniotic twin pregnancy (TP) complicated by twin-to-twin transfusion syndrome (TTTS) was referred to the cardiologist in preparation for fetoscopic laser coagulation (FLC). She was born with a TAPVC to the innominate vein associated with an atrial septal defect (ASD), repaired at the age of 3 months by anastomosing the PVC to the posterolateral wall of the left atrium and closure of the ASD with a pericardial patch. At follow up a few years later she developed asymptomatic mild LV dysfunction and alternating brady and tachyarrhythmias including non-sustained ventricular tachycardias (NSVT). At 17th weeks of gestation she presented mild dyspnoea (NYHA functional class II) and an alternance of sinus bradycardia, atrial fibrillation and NSVT. 2D echocardiography showed moderate LV dilatation and dysfunction (LVEF 47%). She was treated with loop-diuretics, but refused antiarrhythmic and anticoagulant therapy. At 19th weeks, TTTS was diagnosed and successful FLC of placental anastomoses was carried out. Symptomatic worsening of LV function and functional class developed in the ensuing weeks (NYHA III, LVEF 40%). Induction of foetal lung maturity with maternal administration of steroids was carried out at 28 weeks but stopped because of spontaneous preterm labour. After delivery, the arrhythmic burden increased to the point of requiring admission to the intensive care unit (ICU) where pacemaker implant was indicated, but refused by the patient. Diuretics and ACE-inhibitors were titrated, but no beta-blockers nor other antiarrhythmics could be started due to intermittent av block. At discharge, the patient was asymptomatic at rest and there were no clinical signs of heart failure. At 17 months of follow-up, she was still asymptomatic, though LV function remained poor. The 2 newborns were discharged after a stormy 4 months in the neonatal ICU and are still being treated for bronchopulmonary dysplasia and the sequels of intraventricular haemorrages. DISCUSSION We are not aware of other described twin pregnancies in repaired TAPVC with residual LV dysfunction and arrhythmia. As the haemodynamic load of twin pregnancy is more severe and the twin pregnancy itself at high risk both for prematurity and maternal cardiac deterioration, evaluation by a Specialist Multidisciplinary referral Unit should occur before conception especially in mNYHA class III and higher, as per current guidelines.

Abstract Background Heart failure (HF) is one the leading causes of hospitalization in the Western world. Women have a lower rate of HF hospitalization and mortality compared to men. Role of 12-lead electrocardiography (ECG) as a risk marker of future HF in women is not well known. Purpose We studied the association of standard 12-lead ECG and clinical risk factors to HF hospitalization in women and in men separately from a large middle aged general population sample with a long-term follow-up. Methods Standard 12-lead ECG markers were analyzed from 10,864 subjects (48.8% women, N=5,215) of the prospective Mobile Clinic Study, and their predictive value for HF hospitalization was analyzed. Results During the follow-up (29.6±11.2 yrs.), a total of 1,743 subjects had HF hospitalization; out of these, 861 were women (49.4%). Several baseline characteristics, such as age, body mass index, blood pressure, and history of prior cardiac disease predicted the occurrence of HF both in women and men (P<0.001 for all). After adjusting for baseline variables, ECG sign of left ventricular hypertrophy (LVH) (P<0.001), and atrial fibrillation (P<0.001) were the only baseline ECG variables that predicted the future HF in women. In men, HF was predicted by fast heart rate (P=0.008), T wave inversions (P<0.001), abnormal Q waves (P=0.002), and atrial fibrillation (P<0.001). Statistically significant gender interactions in prediction of HF were observed in ECG sign of LVH (P<0.001), inferolateral T wave inversions (P=0.005), and heart rate (P=0.012). Conclusions ECG sign of LVH predicts future HF in middle-aged women independently, and T wave inversions and elevated heart rate are associated with HF hospitalization in men in.

Background Left ventricule (LV) function plays an important role in the pathophysiology of decompensation after acute ST elevation myocardial infarction (STEMI). LV remodeling (LVR) after STEMI is associated with development of heart failure, predicting poor clinical outcome therefore its identification is of clinical importance to set up preventive strategies. Prediction of the left ventricular remodeling (LVR) after STEMI in patients treated by primary PCI is challenging. Purpose Finding an echocardiographic parameter that can predict left ventricular remodeling in time after STEMI. Materials and methods In this prospective study we included 30 consecutive patients, median age 60 (37-79), 76% male, with STEMI treated by primary PCI. We performed conventional 2D transthoracic echocardiography for all included patients. In addition to conventional parameters we measured LV global longitudinal strain (GLS) and LV mechanical dispersion using 2D speckle tracking imaging technique. For morphological and functional analysis of LV we used 3D echocardiography (volumes, LVEF) considering its superiority in assessment of LV. All measurements were performed at baseline (up to 7 days after STEMI) and at 5 year follow up. LVR was defined as an increase of over 15% of the LV end diastolic volume (LVEDV) in time, at 5 years after the STEMI. Results We obtained significant differences in time (up to 7 days after STEMI vs at 5 years) between 3D LVEF (46,48 vs 51,68, p = 0.002), LVEDV (97,12 vs 107,76, p = 0.000), 2D global strain (-11.76 vs - 14,1, p = 0.00), and mechanical dispersion (65,06 vs 57,66, p = 0.00) in all patients. LV remodeling at 5 years (15% increase in LVEDV) was observed in 36,6% of the included patients. At 5 years follow up, LVEDV mean value in the remodeling group was 130 ml and in the no remodeling group 90,21 ml (p = 0.002), 3D LVEF was 48,18 vs 54,42 (p = 0.05), global strain was - 12,33 vs -15,35 (p = 0.02) and LV mechanical dispersion 66,27 vs 55,55 (p = 0.05). Therefore patients with LV remodeling in time had lower LVEF, lower global strain and higher LV mechanical dispersion at baseline. Using ROC analysis we identified two cut off values, one of -11.55 for global LV strain measured at baseline (Sb 81.8%, Sp 77%, AUC 0.776, CI 95%, p = 0.022) and the other one of 63.7 for LV mechanical dispersion at admission (Sb 72,7%, Sp 62%, AUC 0.734, p 0.05) to discriminate between patients with or without LV adverse remodeling at 5 years after STEMI. We also found, using regression analysis, that GLS and LV mechanical dispersion are able to predict LV remodeling in time. Conclusion Global longitudinal strain and left ventricular mechanical dispersion measured in the acute phase can predict which patient is likely to undergo LV remodeling at 5 years after STEMI. GLS and LV dispersion could be used as predictors for future LV adverse remodeling after STEMI. Larger scale studies are needed to validate these findings.
