Abstract
Background:
Cardiac syndrome X (CSX) is regarded as a form of ischemic heart disease with functional coronary microvascular abnormalities. This abnormal functioning of coronary microvasculature, often associated with endothelial dysfunction, results in a reduced coronary blood flow reserve. The incidence of CSX in patients undergoing invasive diagnostics for coronary heart disease was approximately 20–30%. Moreover, about 60–70% of CSX patients are female. The CSX symptoms are often debilitating and sufferers have a poor quality of life, with costly demand for healthcare services.
METHODS
The quasi-experimental survey was conducted in a teaching hospital. In this study, 100 Iranian outpatients who were referred to the heart clinic were recruited by randomized sampling. CSX patients were asked to fill out the demographic characteristics form and questionnaires in pre-test then after the period of intervention has been performed the post-test.
Results:
The independent t-test for continuous variable and chi - square test for categorical variables were used. There was no significant difference between two groups for all demographic of intervention and control groups, and RM-Manova was done for main research variables. The result revealed that score of knowledge on CSX risk factors was significantly higher in the experimental group (mean = 20.96) & (SD = 1.77), compared with the control group (mean = 16.32) & (SD = 3.12).
Conclusion
The mobile health messaging intervention significantly is useful for CSX Patients. The educational programs and Lifestyle modification represent a highly effective and low-cost intervention in order to improve the adherence to a healthy lifestyle among cardiac patients.
