Bronchoconstriction: Your symptoms are consistent exercise-induced bronchoconstriction (aka exercise-induced asthma). This does not mean you necessarily have asthma. A major goal is to ensure that exercise is not avoided. As your cardiovascular condition improves this may resolve. It it persists or worsens you should see physician for possible medications/inhalers to use and determine need for further testing.
