Do slow breathing exercises improve quality of life and reduce heart rate and blood pressure in hypertensive patients following primary PCI for STEMI?
A structured 8-week slow breathing exercise program significantly improves quality of life and lowers heart rate and diastolic blood pressure in hypertensive patients recovering from primary PCI for STEMI.

Abstract This study was conducted to determine the effects of slow breathing exercises performed following primary percutaneous coronary interventions (PCI) on the heart rate, blood pressure, and quality of life of patients. Data were collected from patients admitted to the cardiology inpatient clinic of a hospital in Türkiye after primary PCI between October 2023 and November 2024. Patients were randomly assigned to intervention ( n = 34) and control ( n = 33) groups. The intervention group performed slow breathing exercises twice daily for 10 min over an 8-week home follow-up period. Both groups monitored their heart rate and blood pressure at home during this time. Data were collected using a “Patient Information Form” and the “MacNew Heart Disease Health-Related Quality of Life Questionnaire” at discharge, as well as at the 4th and 8th weeks post-discharge. In all follow-up measurements, the quality of life of the patients in the intervention group was significantly better than that of those in the control group. Throughout the follow-up period, the antihypertensive medication doses of the patients in the control group needed to be increased significantly more. Slow breathing exercises increased the quality of life and reduced the heart rate and diastolic blood pressure values of patients following primary PCI. The exercises led to decreases in heart rate and blood pressure immediately after they were performed. Registry : ClinicalTrials.gov, TRN: NCT06098222, Registration date: 5 October 2023.
Çelik et al. (2026) conducted an RCT in ST-Elevation Myocardial Infarction (STEMI) post-primary Percutaneous Coronary Intervention (PCI) (n=67). Slow breathing exercises vs. Standard care was evaluated on MacNew Heart Disease Health-Related Quality of Life Questionnaire total score at 8 weeks (p=0.001). Slow breathing exercises performed for 8 weeks significantly improved health-related quality of life and reduced heart rate and diastolic blood pressure in patients following primary PCI.
