Analysis of lung capacity in patients undergoing coronary artery bypass grafting

Abstract

Surgical intervention in cardiac pathologies is necessary when the operative risk is less than the risk of the disorder, and when the benefits on survival exceed the expectations of the medical treatment of the condition. Cardiac anxiety (AC) is the fear of stimuli and sensations related to heart disease, perceived as negative or dangerous, commonly presented by patients with heart disease who underwent cardiac surgery. The objective was to assess whether there is change in the degree of cardiac anxiety in post-cardiac surgery. One prospective cohort study was conducted. After the inclusion and exclusion criteria to sample comprised 25 patients. This work was done on the basis of the Cardiac Anxiety Questionnaire analyzing the frequency of symptoms, attitudes and feelings of the patient. We assessed patients preoperatively and 7 days postoperatively, comparing the values before and after. The research population consisted of 18 men and 7 women with a mean age of 50.0 ±14.02. Regarding the type of surgery, 76% underwent CABG, while 8% mitral valve replacement, 8% replacement of the aortic valve and 8% correction of inter-atrial communication. The average value of cardiac anxiety questionnaire preoperatively was 50.0 ±17 and postoperative average was 29 ±11, obtaining a p <0.005. We conclude that surgery and physical therapy approach postoperatively may reduce the degree of cardiac anxiety.
