Hemodynamic responses were diminished after bilateral vagotomy and abolished after bilateral
sympathectomy.
Conclusion Since activation of cardiac afferent nerves and reflex responses remained intact after
TMLR, but changed after vagotomy or sympathectomy, TMLR does not denervate the heart sufficiently
to be the cause of improved angina after TMLR (Transmyocardial laser revascularization)
