AHA Releases Guide for Cardiopulmonary Exercise Tests

Says CPX provides clinicians with comprehensive information beyond standard exercise testing

MONDAY, June 28 (HealthDay News) -- In response to the increasing clinical value of cardiopulmonary exercise testing (CPX), the American Heart Association has developed the Clinician's Guide to Cardiopulmonary Exercise Testing in Adults to complement existing exercise testing guidelines with details on CPX. The new guide is being released as a scientific statement and published online June 28 in Circulation.

In this Clinician's Guide, Gary J. Balady, M.D., of Boston University, and colleagues provide a comprehensive overview of CPX, with guidelines outlining its integration into clinical practice.

According to the report, CPX provides comprehensive information beyond standard exercise testing that can aid in the management of complex cardiovascular and pulmonary disease. The authors recommend that CPX systems should be properly maintained and calibrated to ensure high-quality data, and should be operated by competent individuals, with CPX test protocol selection necessary for optimization of test data. In addition, they write that CPX data in combination with exercise electrocardiogram data provides optimal use of CPX.

"CPX in clinical populations has been well studied and appears most useful in the evaluation of patients with heart failure and those with unexplained dyspnea," the authors write. "Other uses include the assessment of patients with mitochondrial myopathies, development of the exercise prescription in patients with cardiovascular disease or stroke, and the assessment of disability in patients with cardiac or pulmonary disease."
