  1. How does the classification system for pulmonary hypertension (PH) aid in understanding the pathophysiology, diagnostic evaluation, and treatments for this condition?

  2. What signs and symptoms might increase the suspicion for elevated pulmonary arterial pressures?

  3. What is a rational diagnostic approach to suspected PH?

  4. What is the meaning of an elevated pulmonary pressure determined by echocardiography?

  5. When should right heart catheterization be considered in the evaluation of suspected PH?

  6. What are the key steps in the evaluation and management of acute right heart failure secondary to elevated pulmonary arterial pressure?

  7. What are the common side effects of the medications used to treat PH?

Pulmonary hypertension (PH) is simply defined as a mean pulmonary arterial pressure > 25 mm Hg at rest. However, this deceptively simple definition encompasses a broad spectrum of clinical entities. In this chapter, we will present an evidence-based approach to the care of the patient with elevated pulmonary arterial pressures. Table 244-1 lists landmark studies supporting the approach presented in this chapter.
