Functional capacity of heart failure patients evaluated by cardiopulmonary exercise test and New York Heart Association class.
The purpose of this study was to evaluate the capacity of the New York Heart Association (NYHA) classification to discriminate heart failure (HF) individuals classes II and III using cardiopulmonary exercise test (CPET) variables. Seventeen patients class II (age 44.47±10.11 years; ejection fraction...

Seventeen patients class II (age 44.47±10.11 years; ejection fraction 32.11±10.37%) and 15 class III (age 46.73±8.74 years; ejection fraction 30.46±10.23%) of NYHA participated in this study. They did a maximal CPET in a treadmill ergometer. According to the distribution of data, correlation of Pearson or Spearman was performed and, to compare the functional classes of NYHA, the Student's t-test was used. Significant correlations (p<0.05) between oxygen consumption (VO2) and oxygen pulse (r=0.76), age (r=0.35) and body mass index (r=0.45) were found. There was no significant correlation between ventricular ejection fraction and the others studied variables. Comparing the functional classes of NYHA, significantly differences were found to VO2 and oxygen pulse (p<0.05). In this study, the correlations reflect the complexity in analyzing and understanding the process of disfunction in HF, once probably other factors influence each of the variables studied. The classification of NYHA was effective to differentiate the patients with HF, reinforcing the indication of this stratification to identify different groups of HF patients to scientific researches and therapeutic interventions. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: Portuguese refInfo: holdings: @attributes: islocal: N |
