It has a high mortality rate and is accompanied by a decreased functional capacity and alteration of the quality of life. Objective: This study aimed to assess the cardiovascular functional capacity of a group of patients suffering from heart failure using the 6-minute walk test (6 MWT). Methods: This was a cross-sectional study carried out in the cardiology unit of Douala’s general hospital for 4 months. We included all eligible patients aged 18 years or more who had stable chronic heart failure and gave informed consent. Those who had an acute coronary syndrome (≤1 month), tachycardia (HR ≥ 120 bpm), high blood pressure (SBP ≥ 180 mmHg and/or DBP ≥ 100 mmHg) and reduced mobility due to orthopaedic reasons were excluded. A 6 MWT was done according to the American Thoracic Society guidelines. The 6 MWT result was considered poor for - 450 m and good for >450 m. Results: We recruited a total of 81 patients (61.7% women) with a mean age of 65.9 ± 10.6 years. The most frequent risk factor for heart failure was high blood pressure (77.8%), alcohol consumption(69.1%) and a sedentary lifestyle (53.1%). The left ventricular ejection fraction was mostly preserved (42.0%) or mildly altered (46.9). The 6 MWT results were poor in 55.6% of cases, average in 19.8% of cases and good in only 24.7% of cases. More than half (59.3%) of the participants perceived the effort as being difficult. The cardiovascular functional capacity was significantly associated with age, heart failure stage and physical activity (p Conclusion: Most patients suffering from chronic stable heart failure in the general hospital of Douala have poor cardiovascular functional capacity.展开更多

Although already recognized as a research method in several specialties, 6TC has not been used in rheumatology. Patients with rheumatoid arthritis (RA) may have impaired functional capacity as well as increased cardiovascular mortality. An adequate functional evaluation of these patients is necessary and the 6TC may be useful in this sense. Objective: The aim of this study was to perform the 6-minute walk test in RA patients and to compare the performance with a control group. Method: A cross-sectional study was carried out in which the sample consisted of 85 women, 46 patients with rheumatoid arthritis and 39 healthy controls. A descriptive analysis of the data was performed. One-Way ANOVA methodology was used to compare the patient and control groups followed by the graphic analysis. Results: The distance walked on the 6TC by RA patients was on average 522.2 meters. In the distance control group found in the 6TC was on average 628.8 meters, the difference being statistically significant. Conclusion: In this study the distance covered in 6TC by women with RA was lower than that of healthy women of the same age.展开更多
