Visceral chest pain in unstable angina pectoris and effects of transcutaneous electrical nerve stimulation (TENS)A reviewViszerale brustschmerzen bei instabiler angina pectoris und wirkung der transkutanen elektrischen nervenstimulation (TNS). Eine Übersicht

A substantial proportion of patients with chest pain referred to hospital, show signs of coronary artery disease. Anginal pain could be conceptualized as a warning signal for coronary artery disease and impending death. But, for many reasons this theory is partly disputed. Firstly, not all ischemic episodes are accompanied by anginal pain (silent ischemia). Secondly, chest pain indistinguishable from true angina pectoris may be the result of other abnormalities of thoracic viscera.
