Abstract
Cardiac rehabilitation is considered a cost-effective treatment that optimizes outcomes for cardiac patients. Nowadays, cardiac rehabilitation is spreading rapidly in Vietnam, providing promising preliminary achievements. Exercise stress testing plays a vital role in developing cardiac rehabilitation programs. There are several well-known stress tests in clinical practice, such as the six-minute walk test, exercise stress test, and cardiopulmonary exercise stress test. The choice of test depends on clinical demand, convenience, and availability in the clinics.
