Vascular Health Problems: Hypertension, PVD, and Related Conditions, Lecture notes of Pathophysiology
An overview of vascular health problems, focusing on hypertension, peripheral vascular disease, deep vein thrombosis, varicose veins, arteriospastic disease, thromboangiitis obliterans, and aneurysms. It includes definitions of key terms such as aneurysm, chronic venous insufficiency, thrombus, and embolus. The document also covers risk factors associated with vascular health problems, including hypertension, arterial and venous diseases, aneurysms, thrombophlebitis, raynaud's disease, and buerger's disease. It further discusses the pathophysiology of hypertension, including the regulation of blood pressure, cardiac output, peripheral vascular resistance, and neurohormonal mediators. Useful for medical students and healthcare professionals seeking to understand vascular health issues and their management.

Aneurysm
a dilatation or an outpouching of a wall of an artery or vein that can occur anywhere in body
Chronic venous insufficiency
chronic failure of venous valves to function, resulting in interference with venous blood return to heart and production of generalized systemic edema
Embolus
A foreign object such as a piece of a thrombus floating in bloodstream until such time as it becomes trapped in a vessel
Ischemia https://www.youtube.com/watch?v=PCdLBXb7JO
a deficiency in supply of oxygenated blood caused by a circulatory obstruction; client experiences considerable pain in affected part
Peripheral vascular resistance (PVR)
sum of all resistances within vascular system
Pheochromocytoma
https://www.youtube.com/watch?v=JfguwfFqt- Pheochromocytoma is a rare tumor that usually starts in the cells of one of your adrenal glands and is responsible for about 0.1-2.0% of cases of hypertension; tumor cells release catecholamines that cause episodic and sustained heart palpitations, sweating, headaches, fainting, and hypertensive emergencies
Secondary hypertension
An elevated blood pressure associated with pulmonary, circulatory, endocrine, and renal diseases such as hyperaldosteronism, pheochromocytoma, Cushing's disease, diabetes mellitus, coarctation of aorta, and hyperthyroidism
Systolic pressure of blood against arterial walls when ventricles of heart are contracted Diastolic pressure of blood against arterial walls when ventricles of heart are at rest
Varicose veins https://www.youtube.com/watch?v=9Wf8bLXVwFI
dilated, tortuous leg veins
Primary varicose veins
dilated superficial veins; seldom involves communicating veins; if valvular breakdown occurs, it is caused by hereditary factors
Thrombophlebitis https://www.youtube.com/watch?v=1N_bxIzFGOI
inflammation of a vein with clot formation within that vein
White coat phenomenon
hypertension that occurs in a normotensive client when a health care professional measures blood pressure; differentiation between white coat hypertension and secondary hypertension is essential for effective therapy to begin
