The book "Secondary Hypertension" by Dr. George Mansoor offers a comprehensive analysis of the secondary forms of hypertension that are often overlooked in clinical practice. It highlights advancements in the diagnosis and treatment of these conditions and notes that previous assumptions about the prevalence of secondary causes of hypertension have been significantly underestimated. The work is divided into various chapters that address screening and diagnostic techniques, as well as medical and surgical interventions for known causes of secondary hypertension in adults and children. Notably, it emphasizes lesser-known causes such as obstructive sleep apnea and the effects of medications that can interfere with antihypertensive therapy. This thorough examination makes the book a valuable resource for professionals dealing with hypertension and vascular diseases.
