Background Chronic obstructive pulmonary disease (COPD) is a progressive respiratory condition characterised by airflow limitation and reduced exercise capacity. The Six-Minute Walk Test (6MWT) and Two-Minute Walk Test (2MWT) are commonly used to assess functional exercise capacity in COPD patients. This study aims to evaluate the correlation between the distance covered in the 2MWT and 6MWT with spirometric indices (such as Forced Expiratory Volume in 1 second (FEV₁), Forced Vital Capacity (FVC), and FEV₁/FVC) in COPD patients.

Background/objectives: The association between chronic obstructive pulmonary disease (COPD) and metabolic syndrome (MetS) is a common one, with long-term therapeutic and prognostic impact. In view of the high pulmonary and cardiovascular morbidity and mortality, self-management contributes to decreasing the risk of an acute cardiac event or pulmonary decompensation.
Methods: We conducted a prospective cohort study on 100 patients admitted to Iasi Clinical Rehabilitation Hospital who were divided into two groups according to the presence (67 patients) or absence (33 patients) of MetS.
Averaged oxygen desaturation improves the prognostic value of the six-minute walk test in elderly patients with heart failure.

Heart failure (HF) is a major cause of hospitalization, and exercise capacity is a key prognostic marker. The six-minute walk test (6MWT) is widely used to assess exercise capacity, but six-minute walk distance (6MWD) varies among individuals, especially the elderly. This study aimed to assess the hypothesis that Δ[Formula: see text]-Ex, the average oxygen desaturation during the 6MWT, could enhance the prognostic value of 6MWD in elderly patients with HF for cardiovascular risk prediction.

Article Synopsis
- A study in Lithuania evaluated outcomes in 87 elderly patients hospitalized with chronic heart failure (CHF) using various diagnostic methods, including transthoracic impedance cardiography and NT-proBNP levels.
- Key results showed that high thoracic fluid content, elevated NT-proBNP levels, short walking distance, and specific changes on chest X-ray are all linked to a poor prognosis in these patients.
- The findings suggest that these parameters can be valuable for assessing the diagnosis and predicting cardiovascular death in CHF patients.
Percent Predicted vs. Absolute Six-Minute Walk Distance as Predictors of Lung Transplant-Free Survival in Fibrosing Interstitial Lung Diseases.

Introduction: Fibrosing interstitial lung diseases (ILDs) often progress despite treatment and become life-threatening, with lung transplant (LTx) remaining the only curative option. Six-minute walk distance (6MWD) is increasingly recognized as reliable predictor of clinical course, especially when longitudinally considered. The use of reference equations to express 6MWD as percent predicted (6MWD%) has not been previously studied in fibrosing ILDs.
