The outcome of the diagnostic exercise test depends on such patient-related factors as age, maximum exercise heart rate, exercise time and severity of the underlying coronary artery disease (CAD).
In the detailed ECG subset, data recorded included exercise time, maximum workload, maximum heart rate, maximum blood pressure, diagnostic change in ST segment, arrhythmias, and reason for stopping (limiting symptoms, ST segment displacement of more than 1 mm 0.08 seconds after the J point, or target heart rate achieved).
Maximum workload and total exercise time were recorded; predicted VO2-peak was calculated automatically taking gender and age into account.
In each session, they will have a warm up period of two minutes at 20% of the short time maximum exercise capacity (figure 2).
We therefore chose a work/recovery ratio of 1 2 that prevents from high lactate accumulation.[ 14] From short time maximum exercise capacity, we will derive the initial work rate for interval exercise (in Watts), which is set at 50% of the short time muscular maximum exercise capacity as measured by the steep ramp test.
If patients have to rest more than twice per session, physical therapists will lower the workload from 50% of the short time maximum exercise capacity by steps of 10% while the length of intervals remains constant.
Then they exercise for 20 minutes at high intensity intervals of 20 seconds at 50% and at low intensity intervals of 40 seconds at 20% of the short time maximum exercise capacity, i.e. with a work/recovery ratio of 1 2.
Our goal of using genetically modified mice with compromised phenotype for performing maximum exercise while obtaining real-time blood pressure measurements was realized by elaborating refined methods for telemetric transmitter implantation and postoperative intensive care.
Of these patients, 818 (65%) had significant CAD, and 852 (68%) were type A. There were no differences between type A and B patients in either maximum heart rate or total exercise time.
The vital clinical variables in this study included blood pressure, the values of body-metabolic status (i.e., FBG, TC, TG, LDL_C, HDL_C, and UA), variables for the measurement of cardiac structure (i.e., LVDd, IVSd, and LVPWd), and variables for the measurement of cardiac function (i.e., EF, FS, treadmill exercise time, METs, maximum net ST segment deviation, and DTS).
