Compare the time course of ischemic endpoints and the need for further medical care in BARI patients receiving PTCA or CABG?
The BARI trial compared secondary endpoints related to ischemia, such as angina, anti-angina medication, ischemia on treadmill, repeat hospitalizations, and repeat revascularization procedures in the two randomized reports. Each o f these ischemia markers showed more abnormalities in patients treated with angioplasty. Both therapies were quite effective in relieving angina and decreasing ischemia on treadmill testing. However, small but significant differences in these parameters suggested CABG provided more definitive relief of myocardial ischemia than PTCA. Need for secondary procedures was most marked in the PTCA group, which required one or more secondary procedures in 70% of the PTCA population at five years in comparison to 10% of the CABG population. However, with the use of one or more additional PTCAs, only 30% of the PTCA population required CABG within five years. Therefore, for patients with an overriding goal to avoid CABG, the choice of PTCA will be 70% effective in achie
