In brief Carotid pulse counting is widely used to monitor exercise intensity. However, some researchers believe it may underestimate postexercise heart rates by initiating the carotid sinus reflex. This study compared carotid, radial, and ECG pulse rates in 20 asymptomatic adults. The authors concluded that carotid pulse counts can be used safely by many healthy adults, but because at least one subject had low heart rate counts after carotid palpations, they present some guidelines: Exercisers should (1) perform the procedure correctly, (2) periodically compare the carotid and radial pulses, and (3) exercise at the lower range of their target heart rate zone.

Objectives: The enormous burden that cardiovascular diseases put on individuals and societies warrants reliable biomarkers of disease risk to optimize disease prevention. We studied longitudinal movement (LMov) in arterial walls using ultrasound of the common carotid artery (CCA). We believe that LMov could be a sensitive biomarker of cardiovascular health and in this study, we evaluate the intra-observer repeatability and inter-observer precision of our method.

The brain is highly innervated by sympathetic nerve fibres; however, their physiological purpose is poorly understood. We hypothesized that unilateral cerebral norepinephrine (NE) spillover, an index of cerebral sympathetic nerve activity (SNA), would be elevated when engaging the baroreflex [via lower-body negative pressure (LBNP; -20 and -40 Torr)] and respiratory chemoreflexes [via carbon dioxide (CO) administration (+8 Torr)], independently, and in combination. Twelve young and healthy participants (5 females) underwent simultaneous blood sampling from the right radial artery and internal jugular vein.

This study aimed to analyze the clinical characteristics and prognosis of Takayasu's arteritis (TA) with carotid artery occlusion in children. This study collected clinical data and follow-up information on the first diagnosis and treatment of c-TA combined with carotid artery occlusion in pediatric patients at the Children's Hospital affiliated with the Capital Institute of Pediatrics and Inner Mongolia Medical University Affiliated Hospital from 2013 to 2023. This study included four female patients with a mean age of (13.

Rationale And Objectives: Increased aortic or central arterial stiffness (CAS) is a major factor in cardiovascular morbidity and mortality in patients with vascular risk factors. Decreased glomerular filtration rate (GFR) and increased urinary albumin excretion (uALB) are associated with lethal and non-lethal cardiovas-cular events. The pathophysiological mechanisms of this association are not fully defined.

Endovascular arterial recanalization has become the mainstay therapy for peripheral arterial occlusive disease. Although immediate technical success is achieved in greater than 90% of cases, longer-term results continue to vary based on the clinical presentation, and the treated target lesion. In the current era, sustained patency can be expected following intervention in the carotid, coronary, renal, and iliac arteries.
