Pulmonary Arterial Enlargement is Associated with Acute Chest Pain in Patients without Coronary Artery Disease

Background: Pulmonary hypertension (PH) is an uncommon cause for chest pain in patients without significant coronary artery disease (CAD). Therefore, we studied the association between chest pain, right ventricular dimensions (RVDs), and PA size on coronary coronary tomographic angiography (CCTA). Materials and methods: It was a prospective study done from the February 1, 2015 to August 31, 2015. Total of 98 patients were identified, 67 in the chest pain and 31 in the non-chest pain group. Results: Patients with chest pain without CAD showed markedly dilated right atrial and ventricular chambers compared with standard parameters. PAD was measured as 24.81± 0.47 mm in the chest pain group and 21.91 ± 0.41 mm in the control group (P
