Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Question: Does chronic reduction of myocardial ischemia attenuate coronary collateral development in miniswine?
Answer: We conclude that growth and development of the coronary collateral circulation measured functionally during exercise at 90% of maximal heart rate is unrelated to the extent and duration of myocardial ischemia in this model.
no

Question: Does preinjury beta blocker usage affect the heart rate response to initial trauma resuscitation?
Answer: Preinjury beta blockade is associated with a slower presenting heart rate, more bradycardia, less tachycardia, but no difference in mortality or ability to achieve a normal heart rate with resuscitation.
no
