The purpose of this note was the impact of physical exercise on release of cardiac troponins. Were evaluated 16 dogs, 8 clinically healthy (group A) and 8 (Group B) with valvular disease in the asymptomatic phase (class I, NYHA). All dogs, after a complete cardiac evaluation, underwent at exercise on a motorized treadmill with different speeds: 1.8 km/h (low speed), 3.6 km/h (medium speed), 5.4 km/h (high speed) lasting 6 minutes, each performed on different days. Plasma samples for the determination of cTnI and cTnT were taken before exercise on a treadmill and at the end of the recovery period, then in 2, 4 and 6 h later, and refrigerated at -20 ° C. cTnI concentrations were increased in Group A only to speeds higher, while cTnT showed no changes. The results suggest objectively that exercise may induce myocardial suffering.

Abstract

The purpose of this note was the impact of physical exercise on release of cardiac troponins. Were evaluated 16 dogs, 8 clinically healthy (group A) and 8 (Group B) with valvular disease in the asymptomatic phase (class I, NYHA). All dogs, after a complete cardiac evaluation, underwent at exercise on a motorized treadmill with different speeds: 1.8 km/h (low speed), 3.6 km/h (medium speed), 5.4 km/h (high speed) lasting 6 minutes, each performed on different days. Plasma samples for the determination of cTnI and cTnT were taken before exercise on a treadmill and at the end of the recovery period, then in 2, 4 and 6 h later, and refrigerated at -20 ° C. cTnI concentrations were increased in Group A only to speeds higher, while cTnT showed no changes. The results suggest objectively that exercise may induce myocardial suffering.
