Description of intervention(s) / exposure
To compare the heart rate response during isometric exercise using a dynamometer Analog palmar prehension (handgrip). Were performed 2 days of sampling with an interval of 5 days between them, consisting of 2 sets of 3 contractions in both days. On the first day of collection performed maximal voluntary contractions in 5 seconds and 10 seconds, held on the second day 30% and 60% of maximum voluntary contraction of 5 seconds.The participants also undergo a program of cardiac rehabilitation for an average duration of 6 months prior to completion of this study (60 minutes per session, 3 times per week, predominantly aerobic, including exercises on a treadmill and cycle ergometer at an intensity between 70 and 75% heart rate reached during the exercise test clinically).
The study was observational prospective.

Outcomes
Primary outcome [1] 238112 0
Evaluate the responses of heart rate during three isometric contractions of different intensities in patients with coronary artery disease and / or risk factors for it.
The isometric contractions were performed using an analog of palmar prehension dynamometer (Jamar - Sammons Preston, Inc. Bolingbrook, IL, USA), with the patient sitting in a chair with back support and adjustable arm so that the bending angle the forearm maintained at 90.
