Arterial structural and functional remodeling is recognized as a key determinant of incident heart failure, although the contribution of arterial properties on left ventricular (LV) remodeling is not ...
The study cohort consisted of 539 participants without overt cardiac disease who underwent extensive cardiovascular examination. Aortic root diameter was measured by two-dimensional echocardiography a...
Aortic root diameter and ePWV were correlated with LV mass index and LVGLS, while only ePWV was related to E / e' ratio. In multivariable analysis, aortic root diameter and ePWV were significantly rel...
Aortic root size and ePWV were independently associated with unfavorable LV remodeling in individuals free of cardiac disease, which might provide useful information into the pathogenesis-linking arte...
Cardiac sarcoidosis (CS) is an important cause of cardiomyopathy. The trajectory of left ventricular ejection fraction (LVEF) in patients with CS undergoing treatment remains unclear. Patients with CS...
Peripartum cardiomyopathy (PPCM) is a rare type of cardiomyopathy that manifests as acute heart failure associated with pregnancy. Delays in early identification result in poor recovery of left ventri...
All baseline and clinical parameters were prospectively collected from a cohort of patients with PPCM admitted to Dr. Hasan Sadikin General Hospital in Bandung, Indonesia between January 2014 and Dece...
This prospective cohort study included 113 patients with PPCM (84 recovered and 29 non-recovered patients). Significant mitral regurgitation (MR), left ventricular ejection fraction (LVEF) <30%, left ...
PPCM recovery score is a convenient scoring system based on clinical and echocardiography assessment that may assist in distinguishing which patients are more likely to develop poor LV function recove...
Iron deficiency anemia (IDA) is a common health problem worldwide. The objective of this study was to noninvasively and quantitatively evaluate early changes in left ventricular systolic function in p...
Sixty-two patients with IDA were selected and divided into two groups based on hemoglobin (Hb) concentration: Group B with Hb > 9 g/dL and group C with 6 g/dL < Hb < 9 g/dL. Thirty-three healthy indiv...
Compared to group A, GWI and GCW were reduced in group B (both P < 0.01). Compared with groups B and A, GLS, GWI, GCW and GWE, and E/A were all diminished, and GWW, LVEDV, LVESV, and E/mean e' were al...
LV-PSL allows noninvasive quantitative assessment of early impaired LV systolic function in IDA patients with preserved LV ejection fraction, and GWI has high sensitivity and specificity compared with...
Left atrial (LA) strain has emerged as a useful parameter for the assessment of left ventricular (LV) diastolic function and the estimation of LV filling pressures. Some have advocated using LA strain...
Spirometric abnormalities have been related to incident heart failure in general population, who generally have preserved left ventricular ejection fraction (LVEF). We aimed to investigate the associa...
Subjects presenting with exertional dyspnoea and received spirometry and echocardiography were eligible for this study. Forced vital capacity (FVC) and forced expiratory volume in the first second (FE...
Among a total of 8669 participants (65.8 ± 16.3 years, 56% men), 3739 (43.1%), 829 (9.6%), 3050 (35.2%) and 1051 (12.1%) had normal, obstructive, restrictive and mixed spirometry pattern, respectively...
The restrictive spirometry pattern or the declined FVC was associated with left ventricular diastolic dysfunction, which aggravated the long-term mortality in the ambulatory dyspnoeic subjects....
Coronary microvascular dysfunction (CMD) has been proposed as an important pathophysiological mechanism in Takotsubo syndrome (TTS). Our aims were (i) to evaluate and compare levels of CMD in patients...
We conducted a prospective study of 27 female TTS patients and an equally sized, age- and gender-matched, cohort of INOCA patients. Coronary microvascular function was quantified invasively using the ...
Coronary microvascular dysfunction is common in patients with TTS and more frequent than in patients with INOCA. CMD in TTS is more severe in the apical compared with the midventricular phenotype of t...
The relationship between left ventricle (LV), extracellular matrix remodeling and fibrosis-linked amphiregulin (ARG) in cirrhotic cardiomyopathy (CCM) is unknown. The aim of the study was to investiga...
Significant left-to-right shunt across a ventricular septal defect (VSD) may lead to left ventricle (LV) volume overload and dilation. The acute loss of LV preload after repair of VSD may contribute t...
To explore left ventricular structural/functional abnormalities in preeclampsia patients by using multimodal echocardiography and to analyze the cardiac impact in preeclampsia subtypes....
A total of 103 individuals, including 64 preeclampsia patients and 39 healthy pregnant women were recruited for this study from 2019 to 2021. There were 34 patients with preeclampsia with severe featu...
EO-SPE patients showed decreased left ventricular ejection fractions, peak longitudinal systolic strain at apical four-chambers, peak circumferential, and radial systolic strain at the apical and mitr...
EO-SPE patients were characterized by left ventricular injury and systolic function reduced. LO-SPE patients were characterized by left ventricular hypertrophy and reduced diastolic function. Multimod...
