Artery Research

Previous studies have demonstrated that the compliance of peripheral artery changes with arm movement. This study aimed to quantify the bilateral difference in radial artery pulse morphology with one-side arm movement. Twenty-four healthy subjects were recruited. Radial artery pulses were synchronously...

Introduction: Common carotid artery (CCA) intima-media thickness (IMT), lumen diameter, and maximum plaque thickness were assessed on ultrasound images. The objective of the study was to evaluate the intra- and inter-reader reproducibility of the measurements following a standardised protocol. Methods:...

Vascular dysfunction may be an important pathway through which ageing and other factors, such as diabetes and obesity, can cause diseases of the heart and brain. Vascular dysfunction includes dysfunction of large arteries (due to arterial stiffness), the microcirculation (microvascular dysfunction) and...

Purpose: To evaluate whether the acute effects of aerobic or isometric exercise on arterial stiffness parameters differ between boys and men. Methods: Fourteen boys (10 ± 2 years, BMI 17.8 ± 1.9 kg/m2) and nine men (26 ± 3 years, BMI 24.4 ± 3.3 kg/m2) completed maximal aerobic and isometric exercise...

Catecholamines are organic compounds derived from amino acids tyrosine and phenylalanine, which acts as neurotransmitters and also functions as hormones in the blood circulation. They bind to plasma proteins and circulate in the blood stream. High levels of catecholamines will cause increase in the heart...

Background: Nowadays, cardiac disease is the most widespread reason of death in most countries such as Iran. Some studies have correlated serum uric acid level with risk of death in the patients of acute coronary syndrome. The study aimed to determine if there is any correlation between serum uric level...

Sleep is a major modulator of cardiovascular function. Since it’s more difficult to maintain adequate sleep duration among night watchmen during their working schedule, so in this study, we hypothesized that, the short sleep duration (<3 h) for 7 days in their night shift schedule, may possibly influence...

Background: Multiple sclerosis (MS) is associated with increased risk of cardiovascular disease (CVD) and approximately 25–54% of patients report poor sleep quality. There is evidence from the general population of an association between poor sleep and increased CVD risk, but this is poorly understood...

Introduction: Arterial restenosis after angioplasty/stenting has hindered coronary artery disease treatment, especially in diabetics. We theorized that gastrin-releasing peptide (GRP) antagonists and growth hormone-releasing hormone (GHRH) antagonists might decrease neointimal hyperplasia and restenosis...

Internal thoracic artery (ITA) and small saphenous vein (SSV) are two viable conduits for coronary artery bypass grafts. The aim of this study was to investigate the viscoelastic behavior of the small saphenous vein and internal thoracic artery under compressive and tensile loadings at body temperature....

Background: Our study was aimed at the assessment of the age-specific hemodynamic response to the active orthostatic test (OT). Methods: Two groups (60-Y/O and 20-Y/O) were subjected to OT (three 5-minute periods: baseline supine, upright standing, recovery supine). Continuous electrocardiogram was...

Objective: To evaluate the cerebral blood flow and the cerebral hemodynamic alteration by Doppler ultrasound in preterms with early onset-neonatal sepsis. Method: Total forty two preterms divided into two groups whether with clinical and laboratory diagnosis of early onset neonatal sepsis (EONS) or...

Background: Increase in central blood pressure is more predictive of future cardiovascular disease than increased brachial blood pressure. Arterial stiffness causes an early return of the reflected pressure wave to the aorta, with subsequently augmented central systolic pressure. It has been reported...
