Anxiety-Driven Hemodynamics in Patients Undergoing Coronary Angiography: A Cross-Sectional Study

Objectives Coronary angiography (CAG) is an essential diagnostic procedure for coronary artery disease (CAD); however, patients frequently experience pre-procedural anxiety, which may affect physiological stability. Therefore, this study aimed to assess pre-procedural anxiety and its impact on hemodynamic parameters among patients undergoing CAG. Material and Methods A descriptive study was conducted from October 2024 to July 2025 among 58 patients undergoing CAG at a tertiary care hospital in Mangalore, India. Participants were selected using convenience sampling. Data were collected using a demographic proforma, the State-Trait Anxiety Inventory (STAI), a sphygmomanometer, and a pulse oximeter. Eligible participants were aged 30–65 years, while those with prior angiography, anxiolytic use, cognitive or psychiatric disorders, hypertensive conditions, or critical illness were excluded. Data were analysed using SPSS v20. Results Among 58 participants, 65.5% were males, with a mean age of 58.39 ± 8.10 years. The STAI results showed that 68.97% of the patients experienced moderate anxiety and 31.03% had mild anxiety, with no cases of severe anxiety. Hemodynamic findings demonstrated elevated mean systolic (142.93 ± 14.26 mmHg) and diastolic blood pressure (87.93 ± 9.78 mmHg) values among the participants. The mean heart rate was 89.32 ± 11.49 beats per minute, reflecting a moderately elevated heart rate. Oxygen saturation remained within the normal range (96.53 ± 3.17%). Conclusion Patients undergoing CAG experienced mild to moderate anxiety accompanied by elevated blood pressure and a modest increased heart rate, highlighting the importance of assessing and managing anxiety to maintain physiological stability and improve procedural outcomes.
