Abstract

A pre-experimental study was conducted among 35 coronary artery disease patients selected by purposive sampling technique who were admitted at Apollo Main Hospitals, Chennai. A pre-experimental, one group pre test & post test design was adopted.  The instruments used for data collection were demographic variables proforma, clinical variables proforma & Modified Karen Yontz stress questionnaire. Pretest was conducted with the help of structured questionnaire to assess the level of stress among selected coronary artery disease patients before progressive muscle relaxation therapy(PMRT). After the pre-test PMRT was administered on the same day through headphone for 2 sessions (morning & evening) over 30 mts with interval of 6 hours.  The PMRT was administered for 3 consecutive days (6 sessions). All the selected CAD patients were informed regarding post-test which was scheduled exactly after 3 days of administration of PMRT. Post test was done on the same group with the help of the same structured questionnaire which was used in the pre-test. This study revealed that PMRT was an effective tool to reduce the level of stress among patients with coronary artery disease.
