Background: Myocardial infarction is a life threatening disease that affects the physical and social conditions of the individuals. Life expectancy and self-efficacy are important to determine the risk of cardiac complications in patients with myocardial infarction. This study was conducted to investigate the effect of short message service intervention on life expectancy and self-efficacy in patients with acute myocardial infarction.
Methods: This single blinded randomized clinical trial study was performed on 80 patients with acute myocardial infarction, hospitalized in Shahrekord university educational centers in 2018. The subjects were selected and randomly distributed in the control and experimental groups. Routine intervention was performed in the control group. In the experimental group, four educational text messages were weekly sent for three straight months. Life expectancy and self-efficacy of these patients were assessed before and immediately after the intervention in both groups. The data were analyzed using descriptive statistics, independent t, paired t and Chi-square tests via SPSS software.
Results: The results showed that the mean difference score of total life expectancy change was significantly different between experiment (12.23± 10.48) and control group (0.06±7.16) (p < 0.001). Mean difference score of self-efficacy in the experiment group (21.94±12.76) was significantly higher than that in the control group (4.66±9.49) (P<0.001).
Conclusion: Using a short message service intervention had positive effects on life expectancy and self-efficacy of patients with acute myocardial infarction. Therefore, this intervention can be used as a low-cost and available method to promote these patients’ life expectancy and self-efficacy.
