Study Notes

Right-Sided Heart Failure

Right-sided heart failure results from a weakened right ventricle, causing reduced blood flow to the lungs.
This leads to blood accumulation in veins, increasing pressure and pushing fluid into tissues, causing swelling (anasarca) in the legs, abdomen, and other areas.

Left-Sided Heart Failure

Left-sided heart failure results in pulmonary congestion, characterized by crackles, S3 heart sound, and dyspnea on exertion (DOE).
Other symptoms include orthopnea, dry cough, oliguria, and weight gain.

Causes of Heart Failure

Coronary artery disease and heart attacks are common causes.
Cardiomyopathy, both genetic and viral, can contribute to heart failure.
Congenital heart disease, present at birth, can lead to heart failure.
Hypertension, or high blood pressure, is a significant risk factor.
Arrhythmia, an irregular heartbeat, can strain the heart.
Kidney disease can impact heart function.
Obesity (BMI over 30), tobacco and recreational drug use, alcohol use, and certain medications like chemotherapy drugs can contribute to heart failure.

Symptoms of Heart Failure

Shortness of breath, especially at night, is a common symptom.
Chest pain, heart palpitations, and fatigue are also associated with heart failure.
Ankle and leg swelling, weight gain, and nocturnal urination are characteristic signs.
Dry cough, abdominal bloating, loss of appetite, and nausea can be present.

Complications of Heart Failure

Irregular heartbeat, sudden cardiac arrest, and heart valve problems can occur.
Fluid accumulation in the lungs (pulmonary edema) and pulmonary hypertension can develop.
Kidney and liver damage are potential complications.

Diagnosis and Treatment of Heart Failure

Assessment, blood tests, cardiac catheterization, chest X-ray, echocardiogram, heart MRI, cardiac CT, EKG, stress test, and genetic testing help diagnose heart failure.
Treatment focuses on lifestyle changes, medication, and surgery.
A low-sodium diet and fluid restriction are encouraged.
Medications include ACE inhibitors, beta-blockers, and diuretics.
Left ventricular assist devices (LVADs) may be considered.

Atherosclerosis

Atherosclerosis is the buildup of plaque within arteries, narrowing the vessel and reducing blood flow.
The condition often remains asymptomatic until significant narrowing or blockage occurs.
Symptoms can include shortness of breath, chest pain (angina), heart palpitations, fatigue, peripheral artery disease (PAD), and elevated blood pressure.

Diagnosis and Treatment of Atherosclerosis

Diagnosis involves physical examination, blood tests, angiography, CT scan, EKG, exercise stress test, and carotid ultrasound.
Treatment includes lifestyle changes, medications (thrombolytics and anticoagulants), and procedures like angioplasty and coronary artery bypass grafting (CABG).

Peripheral Occlusive Disease

Peripheral occlusive disease, also known as arterial insufficiency of the extremities, primarily affects the legs but can involve the arms.
Symptoms include pain, fatigue, decreased walking distance, coldness, and numbness.

Aneurysms

An aneurysm is an abnormal bulge in an artery caused by weakness in the artery wall.
Aneurysms can be asymptomatic or rupture, causing life-threatening hemorrhage.
Fusiform aneurysms bulge on all sides of the artery, while saccular aneurysms bulge on one side.

Aortic Aneurysm

The aorta is the largest artery, extending from the heart to the abdomen.
Abdominal aortic aneurysms (AAAs) are the most common type, affecting the aorta in the abdomen.
Thoracic aortic aneurysms (TAAs) affect the aorta in the chest.
Aortic aneurysms can be deadly, potentially causing a sudden rupture.
Symptoms may include abdominal pain, lower back pain, and pulsating sensations in the abdomen.

Cerebral Aneurysm

Cerebral aneurysms occur in the arteries supplying blood to the brain.
Ruptured brain aneurysms can be fatal within 24 hours.
Approximately 40% of brain aneurysms are fatal, and about 60% of survivors experience neurological impairment or disability.
Ruptured cerebral aneurysms are a major cause of subarachnoid hemorrhage (SAH).

Peripheral Aneurysm

Peripheral aneurysms can occur in arteries outside the aorta.
Common types include popliteal (behind the knee), femoral (groin), carotid (neck), and visceral (bowel and kidney) aneurysms.
Peripheral aneurysms are less likely to rupture than aortic aneurysms.

Causes of Aneurysms

Atherosclerosis, smoking, hypertension, infection, pregnancy, trauma, autoimmune diseases (e.g., systemic lupus), obesity, and genetic factors can contribute to aneurysms.

Symptoms of Aneurysms

Most aneurysms are asymptomatic unless they rupture.
Unruptured aneurysms can obstruct circulation or form blood clots, leading to stroke or other complications.
Abdominal aneurysms may cause pain, back pain, or pulsating sensations.
Thoracic aneurysms can cause difficulty swallowing, breathing, and pain in the chest, jaw, and upper back.

Diagnosis and Treatment of Aneurysms

Diagnosis involves assessment, lab tests, and imaging (ultrasound, CT angio, MRI).
Treatment depends on the aneurysm's size and location.
Unruptured aneurysms may not require immediate treatment, but ruptured aneurysms are considered a medical emergency.
Treatment options include open surgery with a synthetic or stent graft, and endovascular stent-graft surgery.

Deep Vein Thrombosis (DVT)

DVT is a blood clot forming in deep veins, usually in the legs.
DVT can present with leg pain, swelling, or no symptoms at all.
Certain medical conditions, prolonged immobility (e.g., traveling, bed rest), and surgery increase the risk of DVT.
DVT can be dangerous if the clot detaches (embolism), potentially traveling to the lungs (pulmonary embolism) or brain (stroke).

Treatment of DVT

Treatment aims to break up the clot and restore circulation.
Medications include anticoagulants to prevent clotting, thrombolytics to dissolve existing clots, and intravenous pain relievers.
Surgery, like angioplasty, might be used to bypass the clot, using a balloon catheter and stent to open the blocked vessel.

Varicose Veins

Varicose veins are swollen, enlarged veins, commonly appearing on the legs and feet.
They result from malfunctioning valves in the veins, leading to blood backflow and vein dilation.
Varicose veins are often asymptomatic but can cause swelling, aching, and pain.
They may rupture or develop into skin ulcers, requiring treatment.

Causes of Varicose Veins

Weakened veins with faulty valves allow blood to flow backward.
Conditions that increase abdominal pressure, such as pregnancy, constipation, and tumors, can contribute.
Gravity makes it harder for blood to flow back to the heart from the legs, making them a common site.

Symptoms of Varicose Veins

Aching, heavy legs, especially after exercise or sleep., skin shrinking, swollen ankles, spider veins, skin discoloration near the veins, red, dry, and itchy skin, and leg cramps upon standing are typical symptoms.

Complications of Varicose Veins

Venous ulcers, poor circulation, thrombophlebitis (inflammation of a vein), and DVT can occur.

Diagnosis and Treatment of Varicose Veins

Diagnosis involves assessment and physical examination.
Ultrasound and color-flow Doppler ultrasound can help visualize the veins.
Treatment may not be necessary if asymptomatic.
Home remedies like compression stockings often provide relief.
Medical treatment can address pain, complications, or cosmetic concerns.
Options include exercise, weight management, leg elevation, avoiding prolonged standing/sitting, compression stockings, and surgery.
Surgical procedures include ligation and stripping, phlebectomy, and laser treatments.

Hypertension

Blood pressure is the force blood exerts on artery walls, influenced by vessel resistance and heart workload.
Hypertension is chronically elevated blood pressure exceeding 140/90 mmHg.
Systolic pressure (130 mmHg) represents heart contraction, while diastolic pressure (80 mmHg) represents heart relaxation.
Hypertension is a primary risk factor for cardiovascular diseases like stroke, heart attack, heart failure, and aneurysm.

Blood Pressure Ranges

Normal: Under 120/80 mmHg
Elevated: 120-129/80 mmHg
Stage 1 Hypertension: 130-139/80-89 mmHg
Stage 2 Hypertension: 140/90 mmHg or higher
Hypertensive Crisis: Over 180/120 mmHg

Causes of Hypertension

Primary hypertension (essential hypertension) is unknown cause.
Secondary hypertension is due to an underlying condition.

Importance of Managing Hypertension

Controlling hypertension reduces the risk of cardiovascular diseases and promotes overall health.
A single high blood pressure reading may be normal, but sustained elevated readings over time signal hypertension.
