Study Notes

Varicose Veins

Blood pools in veins, causing them to become distended, tortuous, and palpable
Caused by damaged valves and increased pressure due to gravity
Common in people who stand for long periods, wear restrictive garments, or cross their legs
Risk factors: age, female gender, family history, obesity, pregnancy, deep vein thrombosis (DVT), previous leg injury
Can progress to chronic venous insufficiency (CVI)

Chronic Venous Insufficiency (CVI)

Inadequate venous return over a long period
Venous hypertension, circulatory stasis, and tissue hypoxia cause skin ulcerations
Infection can occur due to poor circulation and impaired immune response
Symptoms: edema in the lower extremities, hyperpigmentation of the skin, slow circulation (capillary refill > 3 seconds)
Treatment: elevating legs, compression stockings, exercise, endovenous ablation, sclerotherapy, surgical ligation and stripping

Thrombus Formation in Veins

Thrombus: a blood clot attached to a vessel wall
Embolism: a thrombus that breaks free and travels through the bloodstream
Deep Vein Thrombosis (DVT): a blood clot that blocks veins, typically in the lower extremities
Virchow's Triad: the three factors that promote venous thrombosis: venous stasis, venous endothelial damage, hypercoagulability

Orthostatic (Postural) Hypotension

A decrease in systolic and diastolic blood pressure upon standing
Lack of normal blood pressure compensation in response to gravity
Can be acute or chronic
Signs and symptoms: dizziness, syncope, blurring or loss of vision
Treatment: changing positions slowly, compression stockings, fluid intake, avoiding alcohol, increasing salt intake, eating small meals, exercise

Aneurysm

A local dilation or outpouching of a vessel wall or cardiac chamber
True aneurysms involve all three layers of the arterial wall
False aneurysms are extravascular hematomas that communicate with the intravascular space
Most common locations: thoracic or abdominal aorta, cerebrum
Can lead to dissection or rupture
Risk factors: genetics, smoking, diet, atherosclerosis, hypertension

Clinical Manifestations, Diagnosis, & Treatment of Aneurysms

Clinical manifestations vary depending on location
Diagnosis: ultrasound, CT, MRI, angiography
Treatment:
- If not ruptured: cessation of smoking, reduction of blood pressure and blood volume
- If ruptured or still growing: surgical treatment

Arteriosclerosis/Atherosclerosis

Arteriosclerosis: thickening and hardening of a vessel wall
Atherosclerosis: a type of arteriosclerosis caused by lipid accumulation within the arterial wall, leading to plaque formation
Leading cause of Coronary Artery Disease (CAD) and Cerebrovascular Disease
Risk factors: smoking, hypertension, diabetes, high LDL cholesterol, low HDL cholesterol, autoimmunity
Clinical manifestations: inadequate tissue perfusion, ischemia, infarction
Diagnosis: history of risk factors, lipid panel, glucose reading, imaging
Treatment: stabilizing/reversing plaques with medication, restoring blood flow if obstructed, lifestyle modifications

Peripheral Artery Disease (PAD)

Atherosclerotic disease of arteries that perfuse the limbs, primarily the lower extremities
Narrowed arteries reduce blood flow to the arms or legs
Risk factors: similar to atherosclerosis, with major links to diabetes and smoking
Clinical manifestations: leg numbness, weakness, pain when walking (claudication), no pulse or weak pulse in foot, shiny skin on legs, skin colour changes, slower toenail growth, coldness in the lower leg or foot, sores on toes, legs or feet that may lead to gangrene
Diagnosis: history and physical focusing on atherosclerotic disease, ankle-brachial index (ABI)
Treatment: similar to atherosclerosis, managing risk factors, medications, surgery

Myocardial Infarctions (MI)

Infarction of the myocardium extending from the endocardium to the pericardium (full thickness)
Causes ST elevation on ECG
Clinical manifestations: sudden severe crushing chest pain radiating to the neck, jaw, shoulder, or left arm; back pain (more common in women), indigestion, nausea, vomiting, cool and clammy skin, increased HR and BP
Can result in cardiac arrest due to ischemia, left ventricular dysfunction, and electrical instability
Diagnosis: history and physical examination, ECG results, cardiac troponin elevations
Treatment: aspirin, pain relief (nitroglycerin and morphine), oxygen, positioning in high Fowler's, telemetry monitoring, antithrombotics and anticoagulation, percutaneous coronary intervention (PCI) or thrombolytics if PCI is not available

Post Myocardial Infarction Care

Cardiac monitoring
Bed rest with gradual return to activities of daily living (ADLs)
DVT prophylaxis
Stool softeners
Education: diet, caffeine intake, smoking cessation, exercise

Disorders of the Heart Wall

Disorders of the pericardium: acute pericarditis, pericardial effusion
Disorders of the myocardium: cardiomyopathy (dilated, hypertrophic, restrictive)
Disorders of the endocardium: infective endocarditis, valve dysfunctions (stenosis and regurgitation)
Other: heart failure (left-sided vs. right-sided), rheumatic fever and rheumatic heart disease

Acute Pericarditis

Inflammation of the pericardium
Most often idiopathic, but can be caused by viral infections
Clinical manifestations: chest pain that worsens with respiratory movements or laying down, friction rub at the cardiac apex, ECG changes, new or worsening pericardial effusion
Diagnosis: CT, US, MRI
Treatment: anti-inflammatory drugs, colchicine, aspiration of pericardial effusion if present

Pericardial Effusion & Cardiac Tamponade

Accumulation of fluid in the pericardial cavity
Usually idiopathic, but can be caused by infection; ultimately indicates an underlying disorder
Can lead to cardiac tamponade, a life-threatening condition where pressure on the heart prevents it from filling and pumping effectively
Beck's Triad: low BP, distended jugular veins, muffled or diminished heart sounds
Diagnosis: echocardiogram, CT
Treatment: pericardiocentesis, pain management, potential surgery

Infective Endocarditis

Inflammation of the endocardium
Caused by bacteria, viruses, fungi, parasites
Clinical manifestations: fever, new or changed cardiac murmur, petechial lesions, Osler nodes, Janeway lesions, weight loss, back pain, night sweats, heart failure
Diagnosis: positive blood cultures, echocardiogram, C-reactive protein (CRP)
Treatment: antibiotics

Cardiomyopathies

Conditions that affect the heart muscle, preventing it from efficiently pumping blood
Progresses over time
Treatment can slow progression and improve quality of life
