Left atrial (LA) function and mechanical dispersion changes in breast cancer patients treated with chemotherapy remain unclear.LA function and LA mechanical dispersion in breast cancer patients would be impaired after chemotherapy.This single-center retrospective study included 91 consecutive breast cancer patients treated with chemotherapy and 30 controls. Patients were examined by echocardiography three times at intervals. Conventional parameters, left ventricular strain, LA strain, and LA mechanical dispersion were evaluated and compared.LA strain during reservoir phase (LASr), conduit phase (LAScd), and contraction phase (LASct) all decreased markedly after chemotherapy and were lower than those of the controls (all p .01). The standard deviation of time to peak positive strain during LA reservoir phase corrected by R-R interval (LA SD-TPSr) was significantly increased after chemotherapy and was higher than that of the controls (p .001). The change of LA function was expressed as Δ. Multivariate linear regression analyses showed that LAVIp (0.399, 95% confidence interval [CI]: 0.610, 1.756, p = .000) was independently associated with ΔLASr, LAPEF (-0.325, 95% CI: -45.123, -10.676, p = .002) and age (0.227, 95% CI: 0.021, 0.350, p = .027) were independently associated with ΔLAScd, and LAVImax (0.341, 95% CI: 0.192, 0.723, p = .001) was independently associated with ΔLASct. LAVImax (0.505, 95% CI: 0.000, 0.001, p = .039) and mitral E (-0.256, 95% CI: 0.000, 0.000, p = .024)were independently associated with ΔLA SD-TPSr.Mechanical function of LA declined after chemotherapy in breast cancer patients. With the decrease of LA mechanical function, LA mechanical dispersion assessed by two-dimensional speckle-tracking echocardiography increased significantly, and its clinical value needs to be further studied.

Objective We examined the associations among the circadian rhythms of blood pressure (BP), heart rate (HR) and left atrial function in essential hypertensive patients. Methods The study included 237 essential hypertensive patients who completed 24-h ambulatory BP, HR monitoring and two-dimensional speckle tracking echocardiography (2DSTE). The strain and strain rate images were studied, and the following parameters were measured: left atrial reservoir strain and strain rate (LAS-S and LASR-S), left atrial conduit strain and strain rate (LAS-E and LASR-E), and left atrial booster strain and strain rate (LAS-A and LASR-A). The left atrial stiffness index (LASI) was identified as the ratio of E/e' to LAS-S. All participants were divided into three groups according to the percentage of nocturnal BP dipping (dippers, nondippers and reverse dippers). Results The LASI was significantly higher in BP reverse dippers than in dippers and nondippers. LAS-S, LAS-E and LASR-E were significantly lower in BP reverse dippers than dippers and nondippers. Multivariate logistic regression analysis demonstrated that age, night-time mean SBP and the percentage of nocturnal HR decline were independently related to an increased LASI. Conclusion Impairment of the left atrial reservoir and conduit functions was correlated with abnormal BP and HR circadian rhythms in hypertension. Increased left atrial stiffness was associated with night-time SBP and the percentage of nocturnal HR decline.

Cardiology and Cardiovascular Medicine - Abstract
BackgroundEosinophilic leukemia (EL) is a rare, serious and potentially life-threatening condition characterized by the overproduction of eosinophils leading to tissue eosinophilic infiltration and damage. Although multiple organ systems may be involved, progressive eosinophilic myocarditis (EM) is the most common cause of morbidity and mortality. Early diagnosis and follow-up surveillance combined with multimodal imaging are crucial for appropriate treatment of EM.Case SummaryIt’s a rare case of EL with EM and intracardiac thrombus in a 59-year-old patient who presented with asthenia for 3 weeks. Full blood count analysis indicated significant eosinophilia. Bone marrow aspirate revealed dysplastic eosinophilia and a FIP1L1-PDGFRA fusion gene (4q12) was detected, confirming EL. Echocardiography revealed EM with intracardiac thrombus. This was later confirmed by cardiac magnetic resonance imaging. The patient was commenced on imatinib and prednisolone and good clinical response was obtained. Through 18F-FAPI PET/CT imaging, we obtained in vivo visualization of fibroblast activation changes in the early stage of cardiac structure remodeling. With anti-fibrotic therapy after heart failure, the patient achieved a good clinical response.ConclusionThis case demonstrates in vivo visualization of fibroblast activation after EM. Multimodality imaging can provide early diagnosis and may guide tailored antifibrotic therapy in early stage of EM.

Background: The predictive power of the CHADS2 and CHA2DS2-VASc scores for the presence of Left atrial thrombus (LAT)/ spontaneous echo contrast (SEC) in non-valvular atrial fibrillation (NVAF) is modest. The aim of this analysis is to define clinical and ultrasonic variables associated with LAT/SEC and to propose nomograms for individual risk prediction.Methods: Data on 1,813 consecutive NVAF patients who underwent transesophageal echocardiography (TEE) from January 2016 to January 2021 were collected. The univariate and multivariate logistic regression analyses were used to construct a nomogram. We examined the predictive ability of the risk scores by calculating the area under the curve (AUC). Moreover, the performance of the nomogram was assessed with respect to calibration, discrimination, and clinical usefulness.Results: LAT/SEC was found in 260 (21.0%) and 124 (21.6%) patients in the training and validation cohorts, respectively. On multivariate analysis, independent factors for LAT/SEC were Age, left atrial diameter (LAD), left ventricular ejection fraction (LVEF), hypertension (HTN), previous stroke or transient ischemic attack, Non-paroxysmal AF and a nomogram was built based on these variables. The calibration curve for the probability of LAT/SEC showed good prediction agreement with actual observation. The nomogram achieved good concordance indexes of 0.836 and 0.794 in predicting LAT/SEC in the training and validation cohorts, respectively. Decision curve analysis demonstrated that the nomogram would be clinically useful.Conclusions: In this study, a nomogram was constructed that incorporated six characteristics of NVAF patients. The nomogram may be of great value for the prediction of LAT/SEC in NVAF patients.

Cardiac remodeling is an important pathological process ultimately leading to heart failure. Ubiquitin carboxy-terminal hydrolase 1 (UCHL1) is a deubiquitinase that plays a critical role in neurodegenerative diseases and cancer. However, its role in cardiac remodeling in spontaneously hypertensive rats remains unclear. Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHRs) were administered the UCHL1 inhibitor LDN-57444 (20 μg/kg/day) from 2 months of age for 4 months. Blood pressure, cardiac hypertrophy, fibrosis, inflammation, and oxidative stress were evaluated by the tail-cuff system, echocardiography, and histological analysis. Gene and protein expression levels were examined by real-time PCR and immunoblotting analysis. At 6 months of age, the expression of UCHL at the mRNA and protein levels was significantly upregulated in SHRs compared with WKYs. Moreover, systolic blood pressure, cardiac performance, left ventricular (LV) hypertrophy, fibrosis, inflammation, and superoxide production were significantly increased in SHRs compared with WKYs, and these effects were markedly attenuated by LDN-57444 after 4 months of administration. These beneficial actions were possibly associated with a reduction in blood pressure and inactivation of multiple signaling pathways, including AKT, ERK1/2, STAT3, calcineurin A, TGF-β/Smad2/3, and NF-κB. In conclusion, the results indicate that UCHL1 is involved in hypertensive cardiac remodeling in SHRs, and targeting UCHL1 activity may be a novel potential therapeutic approach for the treatment of hypertensive heart diseases.

To investigate the capacity of biphasic cardiac CT (CCT) for qualitative and quantitative evaluation of different grades of left atrial appendage spontaneous echo contrast (LAASEC). The study included 267 inpatients with confirmed atrial fibrillation who underwent both CCT and transesophageal echocardiography (TEE). CT numbers for LAA, ascending aorta (AA), and left atrium (LA) were identified, and ROC curves for LAA, LAA/AA, and LAA/LA were plotted. With TEE as the standard, the sensitivity, specificity, PPV, NPV, and accuracy of CCT for LAASEC grade ≥ 1 were 60.3, 92.9, 92.4, 64.8, and 75.7%; and for grade ≥ 2 were 100.0, 84.4, 71.4, 100.0, and 88.8% respectively. The values of LAA, LAA/AA, and LAA/LA were significantly larger in LAASEC grade 0 versus 1 and in grade 1 versus 2, but were similar in grades 2 and 3 or in grades 3 and 4. The values of LAA/AA were larger in grade 2 versus 4. When the cutoff value for LAA/AA = 0.897, sensitivity, specificity, PPV, NPV, and accuracy of CCT for LAASEC grade ≥ 1 was 89.6, 83.2, 87.9, 85.5, and 86.9% and with a cutoff for LAA/AA of 0.524, the sensitivity, specificity, PPV, NPV, and accuracy for LAASEC grade ≥ 2 was 98.7, 92.7, 84.1, 99.4, and 94.4%. Although CCT showed limited diagnostic accuracy for grade 1 LAASEC, grade ≥ 2 LAASEC could be excluded when there was no LAA filling defect on first-phase CCT, and TEE can be avoided. CCT has an excellent accuracy in diagnosing LAASEC, and quantitative analysis (in particular LAA/AA) is superior.

Background Left ventricular remodeling (LVr) is common after ST-segment elevation myocardial infarction (STEMI). The aim of this study was to evaluate the prognostic value of speckle tracking echocardiography (STE) for predicting LVr 6–9 months after late percutaneous coronary intervention (PCI) in patients with STEMI. Methods Patients with first STEMI who accepted late PCI were enrolled. Echocardiography was performed within 48 hours of admission. Six to nine months after MI, an echocardiography examination was repeated. LVr was defined as >15% increase in LV end-systolic volume (LVESV) after 6 months. Results One hundred and twenty-seven patients were divided into two groups: 86 patients without LVr and 41 patients with LVr. There were significant differences in the global longitudinal strain (GLS), SD of time to peak longitudinal systolic strain (longitudinal Ts-SD), longitudinal postsystolic index, radial strain (RS), and SD of time to peak radial systolic strain (Radial Ts-SD). In multivariate logistic regression analysis, the GLS(odds ratio [OR] = 0.39, 95% confidence interval [CI] = 0.26–0.57, P

Background The aim of this study was to investigate left atrial (LA) function and synchrony in paroxysmal atrial fibrillation (PAF) patients using two-dimensional speckle tracking echocardiography (STE). Methods Forty-five PAF patients and 30 healthy controls were enrolled. LA peak ventricular systolic longitudinal strain (LAS-S) and strain rate (LASR-S) and left atrial longitudinal strain (LAS-A) and strain rate (LASR-A) during late diastole were determined using STE, and the standard deviation of the time to peak (TPSD) of the regional strains was calculated to quantify LA dyssynchrony. TPSD during ventricular systole and late diastole were named SDs and SDa, respectively. Results Left atrial peak longitudinal strain during ventricular systole (LAS-S) (29.34±8.57 vs 36.73±6.13), LASR-S (1.27±0.311 vs 1.57±0.25), LAS-A (13.11±4.91 vs 17.86±3.57), and LASR-A (−1.51±0.58 vs −1.90±0.30) were reduced in the PAF group compared with the controls (P

Background: The noninvasive evaluation of right ventricular function (RVF) in cardiovascular and pulmonary diseases remains a challenge. Internationally recommended echocardiographic parameters for the evaluation of RVF may not be applicable to China, because of the limited examination time per patient, the varying skill levels of ultrasonographers, inadequate allocation of professional specialties, and outdated instruments and equipment.Methods: Sixty-two patients admitted for right heart failure and 52 healthy volunteers were included in the analysis. The tricuspid annular plane systolic excursion (TAPSE), peak systolic velocity in the tricuspid annulus of the right ventricular free wall (S′), myocardial performance index, right ventricular fractional area change, and Doppler peak strains in the base and mid cavity were evaluated and compared between groups.Results: Compared with the control group, all RVF parameters in the right heart failure group showed significant deterioration (P < .001). However, only TAPSE and S′ were finally included in the discriminant equation. The diagnostic cutoff values derived from the receiver operating characteristic curve were Conclusion: TAPSE and S′ are more suitable than other parameters for the diagnosis of right heart failure in Chinese patients. Different combinations of TAPSE and S′ can be applied effectively for the diagnosis of right heart failure.
