Insights

Radial artery occlusion (RAO) after transradial procedures does not increase the risk of major adverse cardiac and cerebrovascular events. Age and coronary artery disease extension are independent predictors of adverse events.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Medicine

Background:

  • Radial artery occlusion (RAO) is a common complication following transradial procedures.
  • The prognostic implications of RAO on patient outcomes have not been well-established.

Purpose of the Study:

  • To investigate the association between radial artery occlusion and major adverse cardiac and cerebrovascular events (MACCE).
  • To identify independent risk factors for MACCE after transradial coronary procedures.

Main Methods:

  • Prospective study of 837 patients undergoing transradial coronary procedures.
  • Radial artery patency assessed at 24 hours; RAO occurred in 4.8% of patients.
  • One-year follow-up using Kaplan-Meier and Cox proportional-hazards models to assess event-free survival and risk factors.

Main Results:

  • At 1-year follow-up, MACCE occurred in 4.8% of patients (2 with RAO, 35 without).
  • One-year survival rates were similar between groups (94.9% vs. 95%).
  • Age and extent of coronary artery disease were identified as independent predictors of adverse events.

Conclusions:

  • Radial artery occlusion does not appear to have a significant prognostic impact on major adverse cardiac and cerebrovascular events.
  • Age and coronary artery disease extension are significant independent predictors of adverse outcomes following transradial procedures.

Assessment of radial pulse

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

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...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

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...

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...
