Using music to reduce anxiety and stress in patients undergoing coronary angioplasty: A randomized clinical trial protocol

In the current health context, there is a widespread increase in chronic non-communicable diseases that predominantly affect the cardiovascular system. Recent epidemiological data in Brazil indicate a rise in these diseases, which can result in severe harm to patients, including death. This study aims to present a study protocol to evaluate the effect of music in reducing anxiety and stress in patients undergoing coronary angioplasty. A randomized, controlled, double-blind clinical trial will be conducted with 52 patients undergoing coronary angioplasty. The patients will be randomly assigned to one of two groups: a Control Group or an Experimental Group, to assess the effect of music on anxiety and stress. Two key points will be considered to evaluate the intervention's impact: data on patients' anxiety and stress, collected through structured forms, will be gathered both before and after the intervention, along with an assessment of vital signs. The primary expected outcome is a reduction in anxiety and stress, while the secondary expected outcome is stability in vital signs.
