Resistant Hypertension: Secondary Causes and Emergencies

Join our CE course for Physicians, Nurses, and Physician Assistants on Resistant Hypertension in Primary Care to explore the complexities of diagnosing and managing patients whose blood pressure remains uncontrolled despite optimal therapy. Resistant hypertension, defined as blood pressure that remains above goal despite the concurrent use of three antihypertensive agents of different classes, poses significant risks for cardiovascular morbidity and mortality. This course delves into the secondary causes of resistant hypertension, such as renal artery stenosis, primary hyperaldosteronism, and pheochromocytoma, and how early recognition can lead to targeted and potentially curative treatments.

Participants will gain practical tools for identifying hypertensive emergencies and applying evidence-based guidelines to stabilize patients in critical care settings. The course also emphasizes lifestyle modifications, appropriate pharmacological regimens, and strategies for evaluating adherence and white coat hypertension. By the end of this training, participants will be better equipped to manage high-risk patients in primary care and collaborate effectively with specialists in cardiology, nephrology, and endocrinology to improve outcomes.

Educational Objectives

After completing this activity, learners will be able to:

• Define resistant hypertension and identify its underlying causes and diagnostic criteria.
• Recognize the pathophysiology, clinical features, and treatment strategies for renal artery stenosis in the context of resistant hypertension.
• Evaluate endocrine disorders such as pheochromocytoma and primary hyperaldosteronism as contributors to resistant hypertension, and outline appropriate testing and management strategies.
• Apply evidence-based treatment guidelines to manage resistant hypertension and hypertensive emergencies in the primary care setting, including pharmacologic and non-pharmacologic interventions.

Who Should Do This Course

This course is ideal for:

• Physicians specializing in Family Medicine, General Practice, Internal Medicine, Cardiology, Nephrology, and Endocrinology
• Nurse Practitioners and Registered Nurses working in Primary Care, General Medicine, or Patient-Centered Care
• Physician Assistants involved in diagnosing and managing hypertensive patients in outpatient or hospital settings

Did You Know?

• Approximately 10-20% of people with hypertension meet the criteria for resistant hypertension. (American Heart Association)
• Resistant hypertension is associated with a twofold increased risk of cardiovascular events, including stroke and heart failure. (Hypertension Journal, 2018)
• Primary hyperaldosteronism is the most common identifiable secondary cause of resistant hypertension, accounting for up to 20% of cases. (Lancet Diabetes Endocrinol, 2015)
• Renal artery stenosis is responsible for approximately 5% of all secondary hypertension cases and may be corrected with stenting or surgery. (JAMA, 2016)
• Adherence issues account for nearly 50% of cases labeled as resistant hypertension. (Current Hypertension Reports, 2019)
