This was replaced by a protocol in which all patients underwent both exercise testing and CT, and decision making was based on CCS.
Except two cases that underwent both "exercise ECG test" and "ergonovine echocardiogram," diagnostic coronary angiography was performed in 19 patients (90.4%) by the Judkins technique.
The HR was monitored before and during both exercise tests.
Both exercise tests are submaximal, however, the 6MWT is a self-paced while the CET at 75% is a constant load exercise test.
In both exercise tests, the Swiss patients showed higher exercise capacity than the Dutch patients.
Exercise tolerance as assessed by both a maximal exercise test and a 6-minute walk test (6MWT) was shown to be lower than in people with COPD than in sedentary healthy subjects [ 6].
However, all of the studied patients had both a negative exercise test and CFR ≥ 2.0, indicating that there was no significant LAD stenosis [ 7, 8, 27].
The clinical and laboratory characteristics of these subjects did not differ from those of the normotensive group, but higher blood pressure levels were demonstrated during both the ABPM and exercise test.
However, all of the studied patients had both a negative exercise stress test and CFR ≥2.0, indicating that there was no significant LAD stenosis [ 22, 23].
Heart rate (HR) (RS800; Polar Electro, Kempele, Finland) was averaged every 30 s during both the maximal graded exercise test and the intermittent cycling exercise tests.
