Palm temperature monitoring during exercise in patients with heart disease.
The quantitative use of palm temperature changes during a fixed-load treadmill exercise was evaluated in normal subjects and patients with various degrees of cardiac disability. Treadmill exercise revealed different temperature patterns between subject groups. Normal subjects showed an initial transient decrease to a plateau phase, followed by a prompt return to the control level after cessation of exercise. Cardiac patients with severe disabilities showed a progressive decrease during and even after exercise, and the return to the control level was delayed. Patients with less severe cardiac disabilities showed an intermediate pattern. A significant correlation was observed between the temperature pattern and the plasma catecholamine concentration. The simultaneous measurement of forearm and hand blood flow, and palm temperature during a supine ergometer exercise showed that the temperature change reflected the blood flow changes. In conclusion, palm temperature monitoring during treadmill exercise is a simple and useful method for assessment of the vasoconstrictor response to exercise and, therefore, the pattern of temperature changes indicates indirectly the exercise capacity in heart disease.
