Study Notes

Diseases of the Veins

Varicosities: Areas of pooled blood in veins, often saphenous veins. Caused by damaged valves or chronic venous distention.
Chronic Venous Insufficiency: Inadequate venous return over time, leading to ischemic changes in tissues (skin, vasculature).
Superior Vena Cava Syndrome: Compression of the SVC (superior vena cava) often by tumors.

Diseases of the Arteries

Hypertension: Sustained elevation of systemic arterial blood pressure due to increased cardiac output or peripheral resistance.
Atherosclerosis: Inflammatory disease; leading cause of coronary artery and cerebrovascular disease. Starts with endothelial injury, leading to plaque formation.
Peripheral Artery Disease (PAD): Atherosclerosis in arteries supplying the limbs, often asymptomatic but can present with intermittent claudication (leg pain).
Coronary Artery Disease (CAD): Occlusion of coronary arteries, often due to atherosclerosis, reducing blood flow to the heart. Risk factors include age, gender, hypertension, dyslipidemia, and diabetes, among others.
Acute Coronary Syndromes (ACS): Sudden coronary obstruction due to thrombosis (clot formation). Includes unstable angina (reversible ischemia) and myocardial infarction (MI) (irreversible damage).
Myocardial Infarction (MI): Death of heart muscle due to prolonged ischemia. Types include subendocardial and transmural.
Vasospastic Disorders: Include conditions like thromboangiitis obliterans and Raynaud's disease, involving arterioles in the extremities.
