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.

Input: Consider Input: Question: Does transient ischemia limit subsequent ischemic regional dysfunction in humans : a transesophageal echocardiographic study during minimally invasive coronary artery bypass surgery?
Answer: Ischemic dysfunction was precipitated by the 5-min LAD occlusion, as shown by the increase in LVWMS and pulmonary artery pressure. However, a 5-min coronary occlusion and the resulting ischemia do not alter regional left ventricular systolic function during subsequent ischemia in humans.

Output: no


Input: Consider Input: Question: Do gNAS gene variants affect β-blocker-related survival after coronary artery bypass grafting?
Answer: GNAS haplotypes independently associate with an increased risk of death after primary coronary artery bypass graft surgery. These results are most pronounced in patients receiving βAR blockers, strengthening the rationale for personalized treatment, to decrease medication side effects and improve outcomes.

Output: yes


Input: Consider Input: Question: Is cardiac comorbidity a risk factor for mortality and morbidity following surgery for primary non-small cell lung cancer?
Answer: With careful assessment and patient selection, patients with cardiac comorbidity were not found to be at increased risk of mortality and morbidity following lung resection for primary non-small cell lung cancer in a propensity-matched population.


Output: no
