Dear Editor, Cardiac rehabilitation (CR) is among the most important methods of controlling and reducing complications and the mortality rate after a cardiac event or a cardiac surgery (1). Among the various CR program formats, hospital-based cardiac rehabilitation (HBCR) is commonly the first-line treatment in developing countries, such as Iran. However, Iran has a limited number of only 16 HBCR centers in 11 cities: Tehran, Mashhad, Isfahan, Tabriz, Shiraz, Kermanshah, Yazd, Hamadan, Ahvaz, Gillan, and Qazvin. Consequently, many patients must travel long distances and face high financial and time costs to useHBCRservices. . . .
