- Abstract
Background: COPD usually is diagnosed late in its natural course because patients may adapt to the condition or doctors may not notice the symptoms. Spirometry is however only one way of interpreting COPD disease severity. Quantitative assessment of symptoms like dyspnoea, measurement of PEFR and exercise test like 6-minute walk test (6-MWT), which are cheaper modes of diagnosis, can be considered to substitute the spirometry at places where it is not available. Therefore, this study aims to find out correlation of Six Minutes' Walk Test with Spirometric and Clinical parameters in COPD patients. Materials & Methods: A hospital based prospective study was carried out in COPD patients at Government (RVRS) Medical College & Attached groups of Mahatma Gandhi Hospital, Bhilwara, Rajasthan. A total of 50 patients were included in the study, reporting to the OPD or admitted in the wards. At the time of test, the patient's heart rate, blood pressure and oxygen saturation were measured. The 6MWT was performed according to the ATS guidelines. The SPSS 16.0 software package was used for statistical analyses, and a value of p < 0.05 was considered significant. Results: Our study showed that the mean value of six-minute walk distance (6MWD) was 373.5±67.82 in stage I COPD, 266.7±50.88 in stage II, 199.3±63.12 in stage III & 152.2±50.5 in stage IV, which was statistical significant (P<0.0001). It means inverse relationship in six-minute walk distance (6MWD) and severity of COPD. The mean 6MWD was 237.9 ± 86.92 meters (range 88-500 m) and correlated positively to weight, BMI and negatively correlated to breathlessness (mMRC grade) (P<0.0001). Conclusion: Our results suggested that 6MWT can be used as an additional tool in combination with other physiological parameters in assessing the lung function in COPD patients. In conclusion, in COPD patients 6MWT is useful test to assess the severity of disease.
