The Cardiopulmonary Metabolic Exercise Test (CMET) provides a new diagnostic service available to the physician. This represents one of the most effective, sensitive and economic tools that provides accurate reimbursable assessments and functional evaluations. Providing this service makes it possible for a physician’s practice to expand their diagnostic services without any additional equipment or staffing.

Test Overview

Cardiopulmonary Metabolic Exercise Stress Testing (CMET) is the ultimate method of differential diagnostics, enabling the functions of the lungs, heart, circulation and cell metabolism to be analyzed at rest and during exercise. By considering the interaction of all the system components, its diagnostic reliability is far greater than that of isolated individual tests (for example blood gas analysis, spirometry, standard 12-lead ECG treadmill stress test, etc.). Evaluation of exercise performance is an integral component of every medical history. Currently, it is accomplished by means of subjective history taking. Routine exercise testing adds very little information; however, the addition of gas analysis (or cardiopulmonary exercise stress testing [CMET] ) provides the crucial objective assessment by analyzing breath-by-breath oxygen uptake, carbon dioxide production, and anaerobic threshold (AT). Obtaining accurate MET values is critical in terms of patient care. Precisely measuring rather than estimating MET values can prevent misdiagnosis and/or incorrect classification of patients as fit for work or inappropriate missing legitimate opportunities for reimbursement. The CMET test results provide a better indicator of morbidity than other risk factors such as hypertension, history of diabetes, etc. This test also predicts risk of death and prognosis from cardiovascular and pulmonary disease. In addition it is the only non-invasive cardiovascular diagnostic test that can evaluate the heart and lungs as an integrated unit during exercise thus yielding not only information about the heart but also the lungs.
