Abnormal Myocardial Blood Flow Reserve Observed in Cardiac Amyloidosis [PDF]

open access: yes, 2016
We performed real-time myocardial contrast echocardiography on a patient with cardiac amyloidosis and previous normal coronary angiography presenting with atypical chest pain to assess myocardial blood flow reserve (MBFR).

Cardiac Resynchronization Improves Coronary Blood Flow

open access: yesThe Tohoku Journal of Experimental Medicine, 2007
Asynchronous ventricular activation, induced by left bundle branch block, is known to have deleterious effects on the systolic and diastolic functions of the left ventricle (LV). Cardiac resynchronization therapy (CRT) has been proposed as a complementary method to improve the LV systolic performance by restoring the synchronized contraction patterns ...

Alterations in Cerebral Blood Flow after Resuscitation from Cardiac Arrest

open access: yesFrontiers in Pediatrics, 2017
Greater than 50% of patients successfully resuscitated from cardiac arrest have evidence of neurological disability. Numerous studies in children and adults, as well as in animal models have demonstrated that cerebral blood flow (CBF) is impaired after ...

Fractal Rigidity in Migraine [PDF]

open access: yes, 2003
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...

Correlation of carotid blood flow and corrected carotid flow time with invasive cardiac output measurements

open access: yesCritical Ultrasound Journal, 2017
Background Non-invasive measures that can accurately estimate cardiac output may help identify volume-responsive patients. This study seeks to compare two non-invasive measures (corrected carotid flow time and carotid blood flow) and their correlations ...

Influence of BMI on Cardiac Output and Peripheral Blood Flow in Young Adult Males [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Introduction: Obesity is increasing at an alarming rate in young population which has a direct effect on their cardiovascular health resulting in development of hypertension, dyslipidaemia and peripheral vascular diseases at an early stage of life.

Function of arteries and veins in conditions of simulated cardiac arrest [PDF]

open access: yesBioImpacts, 2021
Introduction: The study examined the behavior of vasculature in conditions of eliminated cardiac function using mathematical modeling. In addition, we addressed the question of whether the stretch-recoil capability of veins, at least in part accounts for

The Effects of Involuntary Respiratory Contractions on Cerebral Blood Flow during Maximal Apnoea in Trained Divers. [PDF]

open access: yesPLoS ONE, 2013
The effects of involuntary respiratory contractions on the cerebral blood flow response to maximal apnoea is presently unclear. We hypothesised that while respiratory contractions may augment left ventricular stroke volume, cardiac output and ultimately ...

Postsynaptic α1-Adrenergic vasoconstriction is impaired in young patients with vasovagal syncope and is corrected by nitric oxide synthase inhibition [PDF]

open access: yes, 2016
BACKGROUND: Syncope is a sudden transient loss of consciousness and postural tone with spontaneous recovery; the most common form is vasovagal syncope (VVS).

Congenital heart malformations induced by hemodynamic altering surgical interventions

open access: yesFrontiers in Physiology, 2014
Embryonic heart formation results from a dynamic interplay between genetic and environmental factors. Blood flow during early embryonic stages plays a critical role in heart development, as interactions between flow and cardiac tissues generate ...
