Prediction of Mortality and Morbidity With a 6-Minute Walk Test in Patients With Left Ventricular Dysfunction

Transplante de células da medula óssea na insuficiência cardíaca chagásica: relato da primeira experiência humana

“…At baseline, a clinical evaluation was performed, and the following clinical data and variables were recorded: a) NYHA functional class, b) quality-of-life score based on the "Minnesota Living With Heart Failure Questionnaire" 20 ; c) hematological and biochemical variables; d) twelve-lead electrocardiogram; e) transthoracic echocardiogram; f) sixminute walking test 21 ; g) 24-hour Holter monitoring. After the procedure, patients were referred to the Intensive Care Unit, where they were monitored for at least 24 hours.…”

“…The six-minute walking test was performed according to the protocol used by Bitner et al 21 in the SOLVD study 13 . After a fifteen-minute rest, a new test was carried out, and the average of the distances walked in the two tests was used as the result.…”

Differential response to resistance training in CHF according to ACE genotype

“…The major symptoms of chronic heart failure (CHF) are exertional fatigue and breathlessness (6), with poor exercise capacity being a strong and independent prognostic indicator of morbidity in CHF (7). Aerobic exercise training improves  VO 2 peak and exercise tolerance (8) in these patients, while similar changes coupled with increases in muscular strength have been observed with resistance training (9).…”

Variable effect of comorbidity on the association of chronic cardiac failure with disability in community-dwelling older persons

“…CF has been demonstrated to limit independence in several tasks (Guccione et al, 1994), to have a significantly negative impact on determinants of the quality of life (Guyatt, 1993), to bear an increased risk of disability in older individuals living in the community (Pinsky et al, 1990), and to increase the risk for loss of employment in younger (< 65 year-old) patients with chronic coronary artery disease (Mark et al, 1992). Conversely, it was demonstrated in CF patients that the evaluation of physical function by the 6-min walk test is a predictor of mortality and of the rate of hospital admissions stronger than left ventricular ejection fraction (Bittner et al, 1993). Our data are substantially consistent with these reports.…”
