Pulmonary Hypertension is defined as the mean pulmonary artery pressure measured by right heart catheterization greater than 25mmHg at rest. Symptoms and signs include shortness of breath, lightheadedness, syncope, tiredness, chest pain, swelling of the legs, poor appetite, chest pain, right-sided abdominal pain, palpitations, cyanosis and rarely non-productive cough, exercise-induced nausea, and vomiting. A diagnosis of Pulmonary Hypertension requires clinical suspicion based on symptoms and physical examination. In our daily practice, it is necessary to raise awareness for this patient group, whose diagnosis is delayed, and the specialist referral centers should be determined and the referral chain should be operated. We herein present 3-year Follow-up Results of Abant Izzet Baysal University Training and Research Hospital Patients with Pulmonary Hypertension.
