Student’s Name: Professor’s Name: Course Title: Date of Submission: Hemodynamic Changes in Patients with Pulmonary Hypertension The article clearly defines how hemodynamic changes contribute to pulmonary hypertension and the medication complications associated with the PH drugs. The main shortcoming of the article is that it does not address the technical aspects that define the condition. It fails to give the hemodynamic figures used in diagnosing the PH. Pulmonary hypertension (PH) refers to a hemodynamic state that is characterized by a mean pulmonary pressure of 25 mm Hg and above at resting point. It is defined by chronic elevation PAH and PVR eventually resulting in ventricular enlargement and hypertrophy. Since the definition of PH is based on hemodynamic criteria, it is caused by various diseases and conditions. It may be caused by respiratory and cardiac diseases. PH is classified into various categories based on the clinical characteristics and pathophysiology. PAH diagnosis is determined by assessing whether the mean pulmonary arterial pressure (PAP) is over 25 mmHg or whether the filling pressure of the left ventricular does not exceed 15 mmHg (Steele, et a. 9-12). According to Steele et al. (2010), it is often difficult to differentiate between PAP and PVH. The main diagnosis approach for PH is conducting a right heart catheterization (RHC). RHC is vital in providing valuable diagnostic information that can differentiate PAH and PVH. Several hemodynamic values are vital in providing the prognosis value of idiopathic PAH. The hemodynamic parameters include mean PAP, right arterial pressure (RAP) and cardiac index. It has been established that
