Background and Aims: Accurate blood pressure monitoring is crucial for patients undergoing angiography due to the high prevalence of cardiovascular diseases. The present study aimed to investigate the effect of targeted physical nurse presence on patients' mean arterial pressure (MAP) during the waiting period in the waiting room.
Materials and Methods: This two-group, randomized clinical trial was conducted in Birjand, Iran, from June to October 2023. A total of 70 patients, candidates for their first angiography, were selected by convenience sampling and randomly assigned to either the intervention group (n=35, receiving physical nurse presence) or the control group (n=35, receiving usual care). The MAP was measured by the researcher in two initial stages, non-invasively (using a portable Saadat vital signs monitor) and in the third stage (angiography initiation), invasively (using a catheter and a cath lab pressure transducer). Data were analyzed using an independent t-test, Fisher's test, repeated measures analysis of variance (ANOVA), and analysis of covariance (ANCOVA) (controlling for baseline MAP and age), using the SPSS (version 20) software.
Results: Groups were homogeneous regarding demographic characteristics (P>0.05). Participants' mean age was approximately 60 years, and 57.1% were male. Average MAP before angiography was 92.8±12.7 in the intervention group and 101.1±15.2 in the control group (P=0.016). The ANCOVA results demonstrated a significant reduction in MAP in the intervention group during the pre-angiography and angiography initiation stages, and this effect remained stable after controlling for baseline MAP and age. Additionally, repeated measures ANOVA revealed a distinct pattern of MAP changes over time between the two groups (P<0.05).
Conclusion: Targeted physical nurse presence in the pre-angiography stages suggests potential effectiveness in the reduction of patients' MAP. These findings emphasize on the importance of re-evaluating and incorporating this non-pharmacological intervention into standard care protocols for patients undergoing angiography.
