Insights
The six-minute walking test is safe for heart patients post-percutaneous coronary intervention. It safely assesses functional capacity, with vital signs returning to normal after the test.
Area of Science:
- Cardiology
- Rehabilitation Medicine
- Clinical Exercise Physiology
Background:
- Heart disease is a leading cause of mortality, impacting functional capacity.
- The six-minute walking test (6MWT) assesses functional ability in chronic cardiopulmonary conditions.
- Assessing 6MWT safety in post-percutaneous coronary intervention (PCI) inpatients is crucial.
Purpose of the Study:
- To evaluate the safety of the 6MWT in inpatients following PCI.
- To assess physiological responses during and after the 6MWT in this patient group.
- To analyze changes in vital signs, Borg scale, and angina scale post-PCI.
Main Methods:
- A one-group pre-test/post-test design was employed.
- Thirty inpatients post-PCI performed the 6MWT twice with a rest period.
- Vital signs, Borg scale (including dyspnea and leg fatigue), and angina scale were measured before and after the test.
Main Results:
- The 6MWT was safely completed by all participants, with no major adverse events.
- Systolic/diastolic blood pressure, pulse, and respiratory rate increased during the test and returned to baseline (p<0.05).
- Changes in oxygen saturation, Borg scale ratings for dyspnea/fatigue, and angina scale were not statistically significant.
Conclusions:
- The 6MWT is a safe and feasible assessment tool for inpatients after PCI.
- Physiological responses observed during the 6MWT are within expected parameters.
- The 6MWT provides valuable insights into functional capacity and recovery post-PCI.
Background:
Heart disease is one of the non-communicable diseases that cause the highest mortality. Its symptoms affect the patient's functional capacity and activities. The six-minute walking test can be done to assess a person's functional ability, response to therapy, and prognosis of chronic heart-lung conditions. The study aims to determine the safety of the six-minute walking test in inpatients after percutaneous coronary intervention by assessing the response of vital signs, Borg scale, and angina scale.
Methods:
This study was a one-group pre-and post-test design study with subjects of inpatients after percutaneous coronary intervention at the Integrated Cardiac Service in Cipto Mangunkusumo General Hospital Jakarta. Research subjects conducted a six-minute walking test twice with a five-minute break in between. Examination of vital signs, Borg scale, and angina scale before and after walking test. The number of subjects was 30 (27 male and 3 female) with the majority classified as a low-risk stratification.
Results:
The six-minute walking test was performed over two days or more in 56.7% of the subjects. The mean covered distance was 294.68 ± 57.02 meters. Vital signs of systolic and diastolic blood pressure, pulse rate, respiratory rate, and Borg rating of perceived exertion (RPE) scale increased during the test. They decreased to baseline after resting for five minutes with p-value <0.05 in the Wilcoxon Signed Rank test. Changes in saturation, dyspnea, and leg fatigue of the Borg scale, and angina scale were not statistically significant. All study subjects did not have major adverse events.
Conclusion:
The six-minute walking test is safe to do in inpatients after percutaneous coronary intervention with vital signs, Borg scale, and angina scale change accordingly to physiological response.
