This educational material details the pathophysiology, diagnosis, and management of various cardiovascular and peripheral vascular conditions. It defines hypertension through specific blood pressure stages and highlights how lifestyle factors like smoking, diet, and stress contribute to arterial damage. The text distinguishes between arteriosclerosis, which is age-related vessel hardening, and atherosclerosis, the accumulation of plaque that restricts blood flow. Furthermore, it compares peripheral artery disease (PAD), characterized by oxygen deprivation and "rest pain," with peripheral venous disease (PVD), which involves blood pooling and valve failure. Clinical assessments such as ultrasound, lipid panels, and ankle-brachial indices are presented as vital tools for monitoring these systemic issues. Finally, the sources outline treatments ranging from anticoagulant drug therapy to surgical interventions like revascularization and thrombectomies.
