- Abstract
Echocardiographic evaluation of left ventricular diastolic function relies on a multi-pronged algorithm, which incorporates Doppler-based and volumetric parameters. Integration of clinical data in diastolic assessment is recommended, though not clearly outlined. We sought to develop an automated tool for diastolic function, compare its performance to human-generated diagnoses and identify the common sources of error. Our software tool is based on the 2016 diastolic guidelines algorithm, which uses 8 parameters as input, with 10 conditions as the logic and 5 possible outputs as final diagnoses. Initially, we prospectively studied 563 patients whose diastolic function was independently evaluated by an expert echocardiographer and by the automated tool. Incongruent cases were further analyzed, after which features of myocardial disease were integrated into a refined version of the software that was tested in an independent cohort of 1106 patients. In the initial analysis, 202/563 grades (36%) were incongruent between the automated and human reads, with the highest rate of discordance for mild and indeterminate categories. In 17% of cases, human diagnoses differed from that dictated by the algorithm due to integration of clinical factors. Follow-up analysis using the refined automated tool did not improve the discordance rate (440/1106; 40%). There was more discordance in cases of: age > 40 years, impaired mitral inflow patterns (E/A < 0.8) and reduced mitral e' values. Further analysis revealed differences in how readers interpreted the interaction between these factors and diastolic function, which could not be incorporated into the automated tool. In conclusion, although assessment of diastolic function relies on an algorithm that can be automated, this algorithm does not include clear guidance on how to incorporate age, or age-related changes in Doppler-based parameters, often resulting in discordant diagnoses. Standardized interpretation of these factors is needed to improve the reproducibility of diastolic function grading by human readers and the accuracy of the automated classification., (© 2021.

- Abstract
The purpose of this study was to investigate factors associated with AF in patients with hyperthyroidism beyond heart failure (HF), coronary heart disease (CHD), or valvular diseases. A total of 136 patients (mean age, 52 ± 15 years; 86 [63%] female) who were diagnosed with hyperthyroidism for the first time were enrolled. Patients who had HF, CHD, or significant valvular diseases were excluded. Patients were classified into two groups according to the presence (group 1, n = 40) and absence of AF (group 2, n = 96). AF occurred in 40 (29%) patients and 23 (58%) of these patients showed paroxysmal AF. Among the symptoms of hyperthyroidism, the most common chief complaint was palpitation (30%). Advanced age, presence of prior cerebrovascular events, and presence of palpitations were associated with AF. Larger left atrial volume index (LAVI), increased left ventricular mass index, and decreased left ventricular ejection fraction (LVEF) and S' velocity were associated with AF. Among them, presence of palpitations and increased LAVI were independently associated with the occurrence of AF. In addition, strain analysis, decreased LA expansion index (EI), ejection fraction (EF), peak atrial longitudinal strain, contraction strain, and late diastolic strain rate (A sr) and systolic strain rate (S sr) were associated with the occurrence of AF and LAVI. Presence of palpitations and enlarged left atrium were associated with the occurrence of AF in patients with hyperthyroidism irrespective of conventional risk factors. Additional LA analysis revealed that decreased LA function was associated with AF and enlarged left atrium., (© 2021. The Author(s), under exclusive licence to Springer Nature B.V.)

- Abstract
Systemic chronic inflammation may favor the onset of metabolic syndrome (MetS) which represents a risk factor for CV events. Rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are disorders with high prevalence of MetS. We assessed the factors associated with MetS and its prognostic role in non-selected RA/AS/PsA patients. Between March 2014 and April 2016, 458 patients (228 RA, 134 PsA, 96 AS) selected for a primary prevention program for cardiovascular diseases were analyzed. Primary and co-primary end points were a composite of all-cause death/all-cause hospitalization and CV death/CV hospitalization, respectively. MetS was diagnosed according to the IDF Task Force on Epidemiology and Prevention. Patients were divided into MetS + (73 = 16%) and MetS - (385 = 84%). At multivariate logistic analysis, cancer, moderate/high disease activity, higher LV mass (LVM) and degree of LV diastolic dysfunction were independently associated with MetS. At 36-month follow-up, the event rate for primary/co-primary end point was 52/15% in MetS + vs 23/7% in MetS - (both p < 0.001). At multivariate Cox regression analysis, MetS was related to primary end point (HR 1.52 [CI 1.01-2.47], p = 0.04) together with higher LVM, disease duration and higher prevalence of biologic DMARDs refractoriness, and to co-primary end point (HR 2.05 [CI 1.16-3.60], p = 0.01) together with older age and higher LVM. The RA/AS/PsA phenotype MetS + is a subject with moderate/high disease activity, LV structural and functional abnormalities at increased risk for cancer. MetS + identifies RA/AS/PsA patients at higher risk for CV and non-CV events, independently of traditional CV risk factors analyzed individually and traditional indexes of inflammation.

- Abstract
Background: Preclinical left ventricular diastolic dysfunction (LVDD) is a high-risk state for heart failure. Kidney dysfunction is a known risk factor for heart failure, but its association with asymptomatic LVDD is not well-known., Methods: A hospital-based retrospective cohort study was conducted on patients who underwent echocardiogram between 2006 and 2016 to assess the association between baseline kidney function and LVDD on echocardiogram. E/e' ratio was defined as the ratio of peak velocity of early diastolic left ventricular inflow (E) to mitral annular velocity (e'). The primary outcome was time to development of LVDD, which was defined as E/e' ratio > 14. The changes in the E/e' ratio and other echocardiographic parameters were assessed using a mixed effects model., Results: Among 1167 patients, the mean age was 61 years, and the mean baseline E/e' ratio and ejection fraction were 9.6 and 69%, respectively. During a median follow-up of 3.2 years, 231 (19.8%) people developed LVDD. According to eGFR (mL/min/1.73 m
2 ), the risk for LVDD based on hazard ratio [95% confidence interval (95% CI)] was 1.20 (0.82, 1.75) for 60 to < 90, 1.42 (0.87, 2.31) for 45 to < 60, and 2.57 (1.61, 4.09) for < 45 (P trend < 0.001). The adjusted risks (95% CI) for annual change in E/e' ratio was 0.09 (0.03, 0.14) overall and 0.28 (0.11, 0.45) in the lowest eGFR group; the trend in changes in annual E/e' ratio by baseline eGFR was significant (P trend = 0.01)., Conclusions: Relatively low kidney function was related with the risks for LVDD. Long-term cohort studies are warranted to confirm the association between LVDD and symptomatic heart failure in patients with kidney dysfunction.- Published

- Abstract
To evaluate the changes in left ventricular myocardial function in patients with colorectal cancer undergoing chemotherapy with mFOLFOX6 (oxaliplatin + 5-fluorouracil + calcium folinate) using three-dimensional speckle-tracking echocardiography (3D-STE). Data were collected from 30 patients diagnosed with colorectal cancer in our hospital treated with mFOLFOX6. We used 3D-STE to measure the following parameters of left ventricle function: global longitudinal strain (GLS), global area strain (GAS), global circumferential strain (GCS), global radial strain (GRS), and left ventricular twist (LVtw). Myocardial composite index (MCI) was calculated from measured values (MCI = GLS × LVtw). The above listed parameters were compared before and after chemotherapy. Receiver operating curves (ROC) were prepared for each parameter and analyzed to identify correlations among MCI, LVEF, GLS, and cTnT. Compared with the pre-chemotherapy state, the absolute values of MCI, LVtw, GLS, GAS, GCS, and GRS decreased with increasing cumulative doses of chemotherapeutic drugs. The absolute values of GAS, GLS, MCI, and LVtw decreased after the first cycle of chemotherapy (P < 0.05). The areas under the ROC curves for MCI and GLS were 0.903 and 0.838, respectively. The correlation observed between MCI and cTnT (r = - 0.7228) was found to be stronger than that between GLS and cTnT (r = - 0.6008). In conclusion, 3D-STE may help detect early changes in left ventricular myocardial function caused by mFOLFOX6 treatment in patients with colorectal cancer. MCI is a relatively sensitive index among the various measurable parameters.
