Sex Differences in Diastolic Function Following Myocardial Infarction on Doppler Echocardiography [PDF]

open access: yes
Background Whilst females have relatively greater preservation of left ventricular ejection fraction (LVEF) following myocardial infarction (MI), they have higher rates of heart failure, presumably due to diastolic dysfunction (DD).

Left Bundle Branch Area Pacing Reverts Electromechanical Window Negativity to a Similar Extent as Biventricular Pacing

open access: yesPacing and Clinical Electrophysiology, EarlyView.
BiVP = biventricular pacing; CRT = cardiac resynchronization therapy; EMW = electromechanical window; LBBAP = left bundle branch area pacing; QAoC = Time interval from the onset of the QRS complex to the center of the aortic valve closure artifact; QT = QT interval measured by tangent method.

Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to

Impact of ahemodialysis session on cardiac function in patients withchronic renal failure

open access: yesТерапевтический архив, 2004
Aim. To determine the impact of hemodialysis (HD) session on cardiac function in patients with chronic renal failure. Material and methods. Thirty patients (17 male, 13 female, mean age 49 ± 11 years) on bicarbonate HD were studied.

Reference Values of Tissue Doppler Imaging and Pulsed Doppler Echocardiography for Analysis of Left Ventricular Diastolic Function in Healthy Adults

open access: yes, 2010
To determine reference values for tissue Doppler imaging (TDI) and pulsed Doppler echocardiography for left ventricular diastolic function analysis in a healthy Brazilian adult population. Observations were based on a randomly selected healthy population

Cerebral haemodynamic responses to inspiratory muscle work

open access: yesExperimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Clearance of p16‐positive cardiac cells improves age‐related cardiac remodeling in mice

open access: yesExperimental Physiology, EarlyView.
Abstract Senescent cells are characterized by expression of markers like p16 and secretion of profibrotic and proinflammatory factors. The role of cellular senescence in age‐related cardiac remodeling and dysfunction is incompletely understood. This study aimed to: (i) evaluate the effect of p16‐ positive cell clearance on cardiac function and ...

Three-dimensional color Doppler flow assessment of ischemic mitral regurgitation

open access: yes, 2010
Purpose. Volume-rendered images of the mitral valve apparatus have enabled visualization of the MV leaflets, orifice, and submitral apparatus in a manner that is not possible using conventional 2-dimensional echocardiography.

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

open access: yesExperimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.
