Abstract

Pulmonary embolism (PE) is a life-threatening emergency that is sometimes difficult to diagnose due to nonspecific symptomatology and laboratory findings. A 65 years old women who has past stable angina pectoris history was admitted to the our emergency department with severe acute dyspnea and chest pain. The ECG revealed negative T waves in leads V1 through V6 and initial troponin was 16.8 ng/ml and D-dimer 897ug/L. Since these both laboratory and echocardiographic findings and clinical presentation did not let us establish a definite diagnosis, we sent the patient to the catheterization laboratory in order to perform both coronary and pulmonary angiography. We detected severe stenosis of proximal-mid left anterior descending artery and partially occluded left main pulmonary artery by large thrombo-emboli at the catheterization laboratory and treated successfully.
