Dyspnea is a subjective feeling of difficulty of breath and could be due to many causes. If no cause is found on clinical examination the term unexplained dyspnea is applied. Aim of the work: to evaluate patients with unexplained dyspnea with global longitudinal strain at rest and with dobutamine stress echocardiography. Methods: 43 patients with dyspnea were included in the study. They were divided into 2 groups: group one included 30 patients and group two included 13 patients. All patients have normal baseline echocardiography and negative dobutamine stress echocardiography for ischemic heart disease. Patients were then checked with global longitudinal strain (GLS) at rest and after DSE. Results: patients in group two showed reduced GLS after DSE (12 ± 1%) than in group one (1... view more»
