The examine included sufferers who met particular inclusion standards. These standards required the sufferers to be between the ages of 18 and 60 and keen to endure non-emergency coronary artery graft surgical procedure. Alternatively, exclusion standards included sufferers who skilled lack of consciousness till the day following surgical procedure, those that didn’t have a smartphone, people with extreme postoperative arrhythmias and hemodynamic problems, and sufferers who have been prohibited by their physician from taking part in rehabilitation.


Software program manufacturing

Previous to the software program’s design, intensive analysis was carried out to organize its content material. This concerned reviewing varied texts, together with articles, reference books, and gathering insights from skilled nurses in specialised care items. The content material was then submitted to a panel of 10 specialists for validation, and their steered revisions have been included.

The tutorial content material of the software program coated a variety of matters, together with respiratory diaphragmatic workouts, directions on bodily workouts and their correct execution, discussions and interactions with sufferers, and encouragement for sufferers to interact in routine actions. These ideas have been primarily introduced by means of tutorial movies and interesting animations.

As soon as the content material was finalized, it was handed over to the software program growth and data expertise crew for the creation of the software program. After the preliminary software program was developed, a specialised validation course of was carried out by 10 IT consultants to make sure its performance and effectiveness.

To validate the software program, each white-box and black-box testing strategies have been employed. In black-box testing, customers with no data of the software program’s inside construction enter their desired objects and confirm the recorded info. The goal is to make sure correct knowledge recording. White-box testing, then again, requires customers to have data of the software program’s inside construction and is usually executed by designers or consultants. As an example, to evaluate the software program’s pace, varied objects have been chosen at completely different speeds, and the accuracy of the alternatives was examined.

The subsequent section concerned compatibility testing and safety testing. Compatibility testing concerned putting in the appliance on a number of Android-based smartphones and tablets to evaluate its efficiency on every machine. In safety testing, a double affirmation methodology was applied to make sure correct recording of every affected person’s points. This concerned the affected person confirming their chosen merchandise by clicking once more, decreasing the potential for unintended knowledge entry errors.

The augmented actuality software program was registered and accredited throughout the digital providers system of the Info Know-how Group of Iran.

To guage affected person satisfaction with the augmented actuality software program, the Cellular Utility Score Scale (MARS) was employed.

This scale evaluates the appliance’s high quality and efficiency throughout 4 dimensions: attractiveness (5 questions), performance (4 questions), aesthetics (3 questions), info (7 questions), and subjective high quality (4 questions). Every merchandise within the scale was rated on a 5-point scale. The utmost achievable rating was 115, whereas the minimal acceptable rating was set at 23. For an in depth presentation of the outcomes, please discuss with (Desk 1).

Part I cardiac rehabilitation coaching based mostly on augmented actuality

After establishing the required agreements with officers at Ghaem Hospital in Mashhad, Iran, the primary creator of the examine initiated the sampling course of. Within the intervention group, the rehabilitation program coaching began upon the affected person’s entry into the cardiac surgical procedure intensive care unit and continued till their discharge from the unit.

Throughout a number of periods, augmented actuality software program was utilized to coach sufferers in bodily actions, corresponding to strolling across the inpatient ward and climbing stairs. These workouts have been completed beneath the direct supervision of the researcher and have been individually taught to every affected person utilizing the augmented actuality software program. The period of bodily exercise diverse based mostly on the affected person’s situation and size of hospital keep, starting from 5 to 10 min. All through the rehabilitation periods, ECG and the perceived train depth have been carefully monitored and managed.

Within the management group, the rehabilitation coaching program was applied utilizing a routine methodology based mostly on the Ministry of Well being protocol. The researcher supplied face-to-face coaching throughout the unit. Each the intervention and management teams accomplished the cardiac self-efficacy questionnaire upon admission and on the time of discharge within the particular care unit of cardiac surgical procedure.


Within the knowledge assortment course of, two demographic info questionnaires and a cardiac self-efficacy questionnaire have been utilized.

The cardiac self-efficacy questionnaire used on this examine was the Cardiovascular Administration Self-Efficacy Questionnaire, which was developed by Estka from Italy in 2015. This questionnaire consists of 9 questions, every rated on a 5-point Likert scale, starting from “utterly assured” to “under no circumstances assured.” The questionnaire consists of three subscales.

The primary 4 questions assess an individual’s perception of their capacity to stop smoking, keep correct vitamin, have interaction in train, and keep away from aggravating conditions. This subscale is known as self-efficacy of cardiac danger elements. Questions 5 and 6 pertain to an individual’s confidence in remembering to take medicines appropriately, representing self-efficacy of therapy adherence. Lastly, questions 7–9 consider an individual’s perception of their capacity to establish signs and indicators of illness exacerbation, indicating self-efficacy in symptom recognition.

Every response is assigned a rating, with “not assured in any respect” receiving a rating of 1, “barely assured” receiving a rating of two, “considerably assured” receiving a rating of three, “pretty assured” receiving a rating of 4, and “utterly assured” receiving a rating of 5. The entire scores vary from 9 to 45, with increased scores indicating larger self-efficacy in cardiovascular administration [21]. Borzou et al. (2017) evaluated the validity and reliability of this software in Iran [33]. The sufferers accomplished the Cardiovascular Administration Self-Efficacy Questionnaire each earlier than and after the intervention.

Pattern measurement and randomization

The examine concerned the continual and purposeful number of sufferers who have been then randomly assigned to considered one of two teams. After confirming that they met the inclusion standards, eligible people have been divided into intervention and management teams utilizing a random sequence generated by SPSS software program. This sequence was stored in a sealed envelope to take care of confidentiality. Whereas it was difficult to blind the members on this trial, the end result assessors and statisticians have been unaware of the kind of intervention, guaranteeing a degree of objectivity.

Since no comparable examine was discovered that examined the efficacy of section I cardiac rehabilitation coaching based mostly on augmented actuality on the self-efficacy of sufferers present process coronary artery bypass graft surgical procedure, a pattern measurement of 10 members was decided for every group. The pattern measurement was calculated utilizing the imply comparability formulation, with a confidence interval of 95% and a check energy of 80% for every group, leading to a complete of 20 members. To account for potential dropout likelihood, an extra 30 members have been added to every group, representing a ten% improve from the calculated values within the formulation.

$$N = {textual content{ }}left( {Z1 – alpha /2{textual content{ }} + {textual content{ }}Z1 – beta } proper)2{textual content{ }}left( {S12{textual content{ }} + {textual content{ }}S22} proper)/left( {X1 – X2} proper)2$$

$${Z_{1 – alpha /2}} = {textual content{ }}196$$

$${Z_{1 – beta }} = {textual content{ }}0.85$$

$${X_2} = {textual content{ }}8.3$$

Statistical strategies

After knowledge assortment and sampling, the collected knowledge have been analyzed utilizing SPSS 21. Varied statistical exams have been employed, together with unbiased t-test, Mann-Whitney check, paired t-test, and chi-square check. These exams have been carried out with a 95% confidence degree to make sure statistical significance. Descriptive indicators corresponding to imply, customary deviation, and frequency have been additionally used to supply a complete overview of the information. Cohen’s d was additionally used to judge the magnitude of the impact measurement, calculated by standardized imply distinction, with g > 0.2 to 0.5 = small impact measurement, g > 0.5 to 0.8 = medium impact measurement and g > 0.8 = giant impact measurement [38].
