Cardiovascular Disease, Heart Failure and Hypertension 1 Developed by Gail P. A. Kauwell, PhD, RD, LDN Updated by Gail P. A. Kauwell, PhD, RD, LDN & Anne Mathews, PhD, RD HUN 4446 - Fall 2011 Cardiovascular Disease, Hypertension and Heart Failure • Compare normal structure and function of the heart to the changes that occur in diseases of the heart and blood vessels. • Describe the risk factors, etiology, symptoms, clinical findings and pathophysiology associated with CAD, stroke, MI, heart failure and hypertension. Objectives • Describe the diagnostic tests/procedures and intervention strategies (i.e., medical, surgical, pharmacologic, nutritional) used to treat/manage CAD, stroke, MI, heart failure and hypertension. • Differentiate among CAD, stroke, MI, heart failure and hypertension based on risk factors, etiology, symptoms, clinical findings, laboratory data, diagnostic tests, pathophysiology and medical/surgical, pharmacological and nutritional management. • Relate the signs, symptoms, clinical findings, laboratory data, diagnostic tests, and medical, surgical, pharmacologic and nutritional interventions to the underlying pathophysiology of CAD, stroke, MI, heart failure and hypertension. • Interpret the results of laboratory/diagnostic tests. Objectives • Recommend appropriate nutritional management for patients with CAD, stroke, MI, heart failure and/or hypertension based on information presented in case studies. • Recommend nutritional and lifestyle strategies for reducing CHD risk. • Select appropriate medical, pharmacologic and/or surgical interventions for patients with CAD, stroke, MI, heart failure and/or hypertension based on information presented in case studies.
