Higher ventricular rate during atrial fibrillation relates to increased cerebral hypoperfusions and hypertensive events [PDF]

Scientific Reports, 9: 3779, 2019, 2019
Atrial fibrillation (AF) is associated with cognitive impairment/dementia, independently of clinical cerebrovascular events (stroke/TIA). One of the plausible mechanisms is the occurrence of AF-induced transient critical hemodynamic events; however, it is presently unknown, if ventricular response rate during AF may impact on cerebral hemodynamics.

Revised definition of predicted left ventricular mass using ambulatory blood pressure in healthy Korean adults

Clinical Hypertension, 2017
Background Left ventricular hypertrophy is influenced by both hemodynamic and non-hemodynamic factors. Ambulatory blood pressure is correlated with left ventricular hypertrophy.

Correlation between 24-hour profile of blood pressure and ventricular arrhythmias and their prognostic significance in patients with arterial hypertension [PDF]

Vojnosanitetski Pregled, 2008
Background/Aim. Left ventricular hypertrophy (LVH), apart from arterial hypertension, is a risk factor for electrophysiologic heart condition disorder and sudden cardiac death.

The relationship between left ventricular dilation and right ventricular diastolic function in children with a patent ductus arteriosus

Annals of Pediatric Cardiology, 2023
The impact of a dilated left ventricular (LV) on right ventricular (RV) diastolic function has not been investigated. We hypothesized that in patients with a patent ductus arteriosus (PDA), LV dilation causes elevation of the RV end-diastolic pressure ...

Treatment of Left Ventricular Circulation Disorder: Application of Echocardiography Information Data Monitoring

JMIR Medical Informatics, 2020
BackgroundCardiac hypertrophy induced by pressure overload is one of the important causes of heart failure and sudden cardiac death. At present, there are few studies on the outcome of left ventricular hypertrophy and left ventricular function after ...

Physical model of end-diastolic and end-systolic pressure-volume relationships of a heart [PDF]

Frontiers in Physiology, 2023, 14:1195502, 2023
Left ventricular (LV) stiffness and contractility, characterized by the end-diastolic and end-systolic pressure-volume relationships (EDPVR & ESPVR), are two important indicators of the performance of the human heart. Although much research has been conducted on EDPVR and ESPVR, no model with physically interpretable parameters combining both ...

Comparative characteristics of indicators of peripheral arterial and central aortic pressure, remodeling of the left ventricular myocardium in salt-sensitive and salt-resistant patients with arterial hypertension

Системные гипертензии, 2021
Background. Changes in the vascular wall, in particular, an increase in its stiffness and an increase in pressure in the aorta, as well as hypertrophy of the left ventricular myocardium are factors that determine a poor prognosis in patients with ...
