OBJECTIVES: To compare the procedure’ s costs for myocardial revascularization performed in 2004 and 2015 , and their variations among different cities hospitals accredited by Brazilian Government Health Care System ( BGHS) , by the coronary bypass surgery (CBS) and percutaneous transluminal coronary angioplasty (PTA) among hospitals over a one-year follow up. METHODS: Data from 368 procedures and 86 patients were submitted to 87 CBS and 240 patients to 267 PTA, between January 2015 and December 2015 , and October 2003 and April 2004 respectively , were collected . Each group was subdivided in, Subgroup A ( A1 to A5 ) , B and C , in respect to the manner of payment. RESULTS: The mean cost for A subgroup were R$ 12.985,18 ( USD ~4.400 ) , subgroup B ( CBS ) was R$ 7.759,78 ( USD ~2.900 ) per procedure; in the PTA group the cost/angioplasty was R$ 6.307.79 ( USD ~2.100 ) . At the end of a year, the end values were R$ 7.875,73 ( USD~2.600 ) for the CBS and R$ 8.234,96 ( USD ~ 2.900 ) for the PTA group ( USD RATE 3:1 ) . CONCLUSIONS: The authors concludes that: There is a difference between subgroup A and B , regarding the median cost ( 33 % ) , considering 10 years gap . The cost/angioplasty in the PTA group was minor than CBS group , and 50 % minor than CBS group ten years later.
