Symptom-limited Stair Climbing Test in Heart Failure

Completed

• Conditions: Chronic Heart Failure

• Registration Number: NCT04352426
• Lead Sponsor: KTO Karatay University

Brief Summary

Aims: To assess the efficacy of symptom-limited stair-climbing test (SLSCT), in determining the exercise capacities of patients with chronic heart failure (CHF) in comparison with cardiopulmonary exercise test (CPET) and 6-minute walk test(6MWT) and to interpret the results according to the clinical status of the patients.

Methods: Thirty-one patients, aged 50-75 years, with stage II-III CHF according to the New York Heart Association Classification and left ventricular ejection fraction (LVEF) of ≤45% were included. The demographic and clinical characteristics of the patients were recorded. Exercise capacity was assessed by SLSCT, 6MWT, and CPET. The duration of patients' performance in the test, reasons for ending the test and predicted maximal oxygen consumption (VO2max) were recorded. Heart rate (HR), blood pressure (BP), dyspnoea severity \[Modified Borg Scale (MBS)\] and peripheral oxygen saturation were recorded. Pulmonary functions were assessed by spirometry.
