BACKGROUND: Left ventricular (LV) remodeling is closely linked to the progression of heart failure. There are limited data on the epidemiology of new onset LV remodeling among elderly women, which requires further investigation. METHOD: We examined data from a community-based cohort of women aged > 65 years, who had received > 2 echocardiography scans from 2009 to 2014. Exclusion criteria for patients included prior echocardiographic evidence of left ventricular enlargement (LVE) or hypertrophy (LVH)...

BACKGROUND: The relationship between N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac structural or functional anomalies in pre-clinical, asymptomatic Asian populations has not been well identified. METHODS: From October 2005 to March 2008, we enrolled consecutive asymptomatic adults with preserved global left ventricular (LV) function (ejection fraction>50%) who underwent annual cardiovascular health survey. Circulating NT-proBNP was used to identify echo-defined cardiac structural/functional anomalies and compared to current recommended cut-off from the European Society of Heart Failure...

Obese and diabetic individuals are at increased risk for impairments in diastolic relaxation and heart failure with preserved ejection fraction. The impairments in diastolic relaxation are especially pronounced in obese and diabetic women and predict future cardiovascular disease (CVD) events in this population. Recent clinical data suggest sodium glucose transporter-2 (SGLT2) inhibition reduces CVD events in diabetic individuals, but the mechanisms of this CVD protection are unknown. To determine whether targeting SGLT2 improves diastolic relaxation, we utilized empagliflozin (EMPA) in female db/db mice...

BACKGROUND AND AIMS: The existence of non-excitable cells in the myocardium leads to the increasing conduction non-uniformity and decreasing myocardial electrical conductivity. Slowed myocardial conduction velocity (MCV) believed to enhance the probability of cardiac arryhthmia and alter the cardiac mechanical pumping efficacy, even in sinus rhythm. Though several studies on the correlation between MCV and cardiac electrical instabilities exist, there has been no study concerning correlation or causality between MCV and cardiac mechanical pumping efficacy, due to the limitation in clinical methods to document and evaluate cardiac mechanical responses directly...

Diastolic dysfunction is common in cardiac disease and an important finding independent of systolic function as it contributes to the signs and symptoms of heart failure. Tissue Doppler mitral early diastolic velocity (Ea) combined with peak transmitral early diastolic velocity (E) to obtain E/Ea ratio provides an estimate of the left ventricular (LV) filling pressure. However, E/Ea has a significant gray zone and less reliable in patients with preserved ejection fraction (>50%). Two-dimensional echocardiographic speckle tracking measure myocardial strain and strain rate (Sr) avoiding the Doppler-associated angulation errors and tethering artifacts...

Left ventricular (LV) diastolic dysfunction and subsequent overt heart failure are more prevalent in elderly women. Close interaction between arterial stiffness and LV morphology/function has been reported. The aim of this study was to investigate whether there is an age- and gender-dependent relationship between arterial stiffness and LV diastolic function. A total of 819 subjects (58.6 ± 13.3 years, 50.2% men) without structural heart disease (LV ejection fraction ≥50%) were retrospectively analyzed...

PURPOSE: There exists no consensus on the site of E/e' measurement. This study aimed to evaluate the predictive value of septal and lateral E/e' along with the importance of their intra-individual difference. METHODS: In 1775 persons from the general population, peak early diastolic velocity (e') was obtained by color tissue Doppler at the septal and lateral mitral annular sites. The endpoint was combined of cardiovascular death or admission due to heart failure or acute myocardial infarction...

Left-ventricular (LV) remodelling, associated with diastolic heart failure, is driven by an increase in myocardial stress. Therefore, normalisation of LV wall stress is the cornerstone of many therapeutic treatments. However, information regarding such regional stress-strain for human LV is still limited. Thus, the objectives of our study were to determine local diastolic stress-strain field in healthy LVs, and consequently, to identify the regional variations amongst them due to geometric heterogeneity. Effects of LV base movement on diastolic model predictions, which were ignored in the literature, were further explored...

Constrictive pericarditis (CP) represents a form of severe diastolic heart failure (HF), secondary to a noncompliant pericardium. The true prevalence of CP is unknown but it is observed in 0.2-0.4% of patients who have undergone cardiac surgery or have had pericardial trauma or inflammation due to a variety of etiologies. Despite its poor prognosis if untreated, CP is a potentially curable disease and surgical pericardiectomy can now be performed at low perioperative mortality in tertiary centers with surgical expertise in pericardial diseases...

Heart failure is characterized by the loss of sympathetic innervation to the ventricles, contributing to impaired cardiac function and arrhythmogenesis. We hypothesized that renal denervation (RDx) would reverse this loss. Male Wistar rats underwent myocardial infarction (MI) or sham surgery and progressed into heart failure for four weeks before receiving bilateral RDx or sham RDx. After a further three weeks, left ventricular (LV) function was assessed and ventricular sympathetic nerve fibre density determined via histology...
