The Clinical Effect of Psychological Nursing on Patients Undergoing Coronary Angiography Based on Gold Nanoparticle Contrast Agents

Abstract

To study the clinical effect of psychological nursing on cardiovascular patients undergoing coronary angiography. Sixty cardiovascular patients in our hospital who needed coronary angiography were randomly divided into two groups (30 in each group); contrast agents based on gold nanoparticles were used for all patients. The experimental group received psychological nursing alongside conventional nursing care, and the control group received only conventional nursing care. The two groups were compared for ease of receiving coronary angiography, medical imaging, anxiety, depression, blood pressure, heart rate, efficacy, and patient satisfaction. A gold nanoparticle contrast agent has very low toxicity to cardiovascular endothelial cells, good biocompatibility, and a metabolic effect in vivo. Compared to the control group, the coronary angiography in the experimental group was easier; the medical images were clearer; patients’ anxiety, depression, blood pressure, and heart rate decreased; and curative effect and patient satisfaction were higher. Psychological nursing may significantly improve the psychological and physical condition of cardiovascular patients undergoing coronary angiography, effectively improve the efficacy as well as satisfaction of patients, and has obvious application value in clinical treatment. Similarly, gold nanoparticle contrast agents have important value in the clinical application of coronary angiography.
