Insights

Hand dominance impacts cardiac catheterization outcomes. Using the non-dominant hand for transradial access (TRA) may reduce the incidence of radial artery spasm and occlusion, improving patient safety.

Area of Science:

  • Cardiology
  • Vascular Surgery

Background:

  • Transradial access (TRA) is the preferred method for cardiac catheterization (CC).
  • Minimizing TRA complications is crucial for patient outcomes.
  • Hand dominance is a potential, yet understudied, factor influencing TRA success.

Purpose of the Study:

  • To investigate the influence of hand dominance on radial artery spasm (RAS) and radial artery occlusion (RAO) following CC via TRA.
  • To determine if catheterizing the dominant or non-dominant arm affects complication rates.

Main Methods:

  • A retrospective study of 1713 subjects undergoing CC via TRA between April 2020 and August 2022.
  • Patient data collected included hand dominance of the catheterized side.
  • Radial artery spasm (RAS) and radial artery occlusion (RAO) were assessed during a 1-month follow-up.

Main Results:

  • Radial artery spasm (RAS) occurred in 9.6% of subjects, significantly higher when using the dominant hand (12%) versus the non-dominant hand (7.8%; P = .004).
  • Radial artery occlusion (RAO) occurred in 1% of subjects, also higher on the spasm side (3% vs. 0.8%; P = .009).
  • Hand dominance was identified as an independent predictor of RAS (P = .006).

Conclusions:

  • Both RAS and RAO were more prevalent on the dominant hand side during TRA for CC.
  • Selecting the non-dominant hand for TRA may decrease the incidence of RAS and RAO.
  • Considering hand dominance in TRA procedures could optimize patient safety and reduce complications.

Sites for measruring blood pressure

Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.

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...
