About

This study was designed as a randomized controlled experimental type in order to determine the effect of slow breathing exercise applied after the procedure on heart rate, blood pressure and quality of life in patients who underwent Primary Percutaneous Coronary Intervention (PCI) I after the diagnosis of ST Elevation Myocardial Infarction (STEMI).

Patients who underwent primary PCI due to STEMI in a Training and Research Hospital in Istanbul will constitute the study population. A sample will be formed with a total of 80 patients, 40 experimental and 40 control groups, selected by computer assisted simple randomization method among volunteer patients who underwent primary PCI and met the inclusion criteria.

In this study, slow breathing exercise training will be given to the experimental group by the coordinator. In their home followmup after discharge, they will be asked to do slow breathing exercises for 10 minutes twice a day for eight weeks.

Data will be collected using the "Patient Information Form", "MacNew Heart Disease Health Related Quality of Life Scale", "VAS Breath Therapy Satisfaction Evaluation Form", "Self-Monitoring Form" and "Patient Follow up Form". Patients will be seen again during the outpatient clinic examination in the fourth and eighth weeks and the effectiveness of slow breathing exercises will be evaluated with data collection forms.

Full description

Cardiovascular Diseases (CVD) is still the leading cause of death in the world and in our country, despite significant advances in its diagnosis and treatment. Acute Coronary Syndromes (ACS), which are among the CVD's, occur with the deterioration of the integrity of the atherosclerotic plaque in the coronary vessels. The deadliest form of ACS is ST Elevation Myocardial Infarction (STEMI).

Primary Percutaneous Coronary Intervention (PCI) is recommended primarily in the treatment of acute myocardial infarction. In these patients, changes in vital signs resulting from diagnosis and treatment and a permanent effect on quality of life can be observed.

Slow breathing exercise is a behavioral technique in which a low breathing rate is applied. Breathing exercises reduce heart rate, blood pressure, reduce anxiety and pain while shown to improve symptoms and improve quality of life in patients with chronic obstructive pulmonary disease and asthma. This technique provides conscious deep and slow breathing and effective breathing, as well as improving conscious control over relaxation and increasing awareness.

This study was designed as a randomized controlled experimental type in order to determine the effect of slow breathing exercise applied after the procedure on heart rate, blood pressure and quality of life in patients who underwent PCI after the diagnosis of STEMI. Study data will be collected between 23 October 2023- 30 April 2024 Patients who underwent primary PCI due to STEMI in a Training and Research Hospital in Istanbul will constitute the study population. A sample will be formed with a total of 80 patients, 40 experimental and 40 control groups, selected by computer assisted simple randomization method among volunteer patients who underwent primary PCI and met the inclusion criteria.

In the study, slow breathing exercise training will be given to the experimental group by the coordinator. In their home followmup after discharge, they will be asked to do slow breathing exercises for 10 minutes twice a day for eight weeks. It will be ensured that video calls and breathing exercises are performed together in the form of conference calls.. "Slow Breathing Exercise Training Booklet" and "Slow Breathing Exercise Short Film Video" will be used in the trainings. A calibrated portable digital upper arm sphygmomanometer will be used for heart rate and blood pressure measurement. Groups will be asked to record their own pulse and blood pressure measurements at home.

Data will be collected using the "Patient Information Form", "Mac New Heart Disease Health Related Quality of Life Scale", "VAS Breath Therapy Satisfaction Evaluation Form", "Self-Monitoring Form" and "Patient Follow up Form". Patients will be seen again during the outpatient clinic examination in the fourth and eighth weeks and the effectiveness of slow breathing exercises will be evaluated with data collection forms.

SPSS (IBM Corp., Armonk, NY, USA) program will be used in the analysis of the findings. Before analysis, the normality of the data will be evaluated with the Shapiro-Wilk test. Comparisons between the two groups will be made with descriptive statistics (frequency, percentage, etc.) in the analysis, as well as the Independent Sample t-test (in data with normal distribution) and Mann-Whitney U test (in data that does not show normal distribution) in quantitative data. In comparisons of more than two groups, One-Way Analysis of Variance (One-way ANOVA) or its non-parametric equivalent Kruskal-Wallis test will be used. Paired Samples t-Test or its non-parametric equivalent Wilcoxon test will be used to test the difference in quantitative repeated measurements. Qualitative comparisons between groups will be made with the Chi-Square test. Results, significance in the 95% confidence interval will be evaluated under p<0.05.

Slow breathing exercise training

Experimental group

Description:

Slow breathing exercise training will be given to patients in the experimental group. After discharge, patients will be asked to do slow breathing exercises twice a day for 10 minutes every day for eight weeks. Daily and/or weekly online, weekday, weekend, daytime, evening, video phone calls will be made with patients who are discharged at the end of the training to practice the slow breathing exercise every day according to the patients' demand. It will be provided that breathing exercises will be performed together with a video call in the form of a conference call. Patients will be asked to take measurements a total of two days a week, one day on weekdays and one day on weekends, in the morning, after a light breakfast, at least five minutes of rest and breathing exercises. Pulse and blood pressure measurements at home on weekdays will be asked to be measured Decouply from breathing exercise, and on weekends before and after breathing exercise.

Treatment:

Behavioral: Slow breathing exercise training

Control group

No Intervention group

Description:

In the control group, patients will be shown and told self-blood pressure and pulse measurement at home at discharge. A reminder text message will be sent to the mobile phones of patients for blood pressure and pulse measurement at home. The control group will also be asked to perform their own blood pressure and pulse monitoring at home and record a Self-Monitoring Form (for the Control group).During home follow-up, patients will be sent reminder text messages to their mobile phones two days a week. According to the request of patients, daily and/or weekly online, weekdays, weekends, daytime, evening, phone calls will be made to measure pulse and blood pressure values two days a week.
