Aim:
To evaluate the effects of pre-procedural acupressure on pain, anxiety, and vital signs among patients undergoing transradial coronary angiography.
Design:
A single-blind, three-arm randomized controlled trial was conducted.
Methods:
Ninety-three eligible participants were randomly allocated to acupressure, sham, or control groups. The acupressure intervention was applied for 20 minutes to the HT7, LI4, and PC6 acupoints prior to the procedure. Pain, anxiety, and vital signs were assessed at five time points: twice before transradial coronary angiography and at 0, 2, and 4 hours postprocedure.
Results:
Pain, anxiety, and systolic blood pressure were significantly lower in the acupressure group than in the sham and control groups. No significant differences were observed in diastolic blood pressure, heart rate, respiratory rate, or oxygen saturation.
Conclusions:
Preprocedural acupressure effectively reduces pain and anxiety and contributes to hemodynamic stability in patients undergoing transradial coronary angiography.
Clinical Implications:
Acupressure may be considered a simple and low-cost complementary nursing intervention that could support symptom management in patients undergoing cardiovascular procedures.

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.

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:
