Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

1.5K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Peripheral Artery Disease I: Introduction

133
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Summary

Ultra-endurance running acutely increases arterial stiffness and vascular resistance, as measured by pulse wave velocity and Doppler parameters. However, carotid artery thickness in ultra-marathon runners remains within normal limits.

Area of Science:

  • Cardiovascular Physiology
  • Exercise Science
  • Sports Medicine

Background:

  • Limited research exists on the cardiovascular effects of ultra-endurance exercise.
  • Understanding acute arterial changes post-ultra-marathon is crucial for athlete health.
  • Carotid artery morphology and function are key indicators of vascular health.

Purpose of the Study:

  • To evaluate acute changes in arterial stiffness (carotid-femoral pulse wave velocity).
  • To assess carotid Doppler-derived parameters and intima-media thickness after an ultra-marathon.
  • To investigate the relationship between vascular markers and muscle damage indicators.

Main Methods:

  • Twenty athletes underwent measurements before and immediately after a 246 km ultra-marathon.
  • Key measurements included carotid-femoral pulse wave velocity, carotid blood flow velocities, pulsatility index, resistivity index, and biochemical markers.
  • Carotid intima-media thickness was measured pre-race.

Main Results:

  • Ultra-marathon running significantly increased carotid-femoral pulse wave velocity (22.6%) and pulsatility index (10.2%).
  • Body weight decreased by 3.35%, and muscle damage markers increased post-race.
  • C-reactive protein correlated with post-race pulsatility and resistivity indices.

Conclusions:

  • Acute increases in arterial stiffness and vascular resistance are evident immediately after a 246 km ultra-marathon.
  • Carotid artery intima-media thickness in ultra-marathon runners is within normal ranges.
  • These findings highlight the acute vascular stress induced by extreme endurance events.
