Study Notes

Heart Failure

Elevated Jugular Venous Pressure (JVP): A sign of heart failure, indicating fluid overload and increased pressure in the jugular veins.
Pulmonary Crackles: Abnormal lung sounds during breathing, caused by fluid buildup in the alveoli.
S3 Heart Sound: A third heart sound during heartbeats, indicating volume overload in the heart.
Peripheral Edema: Swelling in legs and ankles due to fluid retention, a common symptom of heart failure.
Acute Heart Failure: Sudden worsening of heart failure symptoms requiring immediate treatment.
Arrhythmias: Increased risk of irregular heartbeats due to heart failure.
Organ Dysfunction: Long-term heart failure can affect the function of other organs, particularly the kidneys.
Diagnosis: Commonly involves a physical exam, medical history review, echocardiogram, chest X-ray, and blood tests (e.g., BNP levels).
Management: Treatment includes lifestyle modifications, medications (diuretics, ACE inhibitors, beta-blockers), and in severe cases, devices (pacemakers) or surgery.

Angina vs. Myocardial Infarction

Angina: Short-lasting chest pain (usually minutes), relieved by rest or nitroglycerin. No permanent heart muscle damage.
Myocardial Infarction: Prolonged chest pain (15 minutes or more), not relieved by rest or medication. Causes damage or death of heart muscle, potentially life-threatening.

Common Symptoms of Cardiac/Respiratory Disorders

Cardiac Disorders

Chest Pain or Discomfort: Feeling of pressure, squeezing, or heaviness, often radiating to arms, neck, jaw, or back.
Shortness of Breath: Difficulty breathing at rest or during activity, accompanied by anxiety.
Palpitations: Sensation of rapid or irregular heartbeats, like fluttering or pounding in the chest.
Fatigue: Unusual tiredness or lack of energy, especially during physical activity.

Complications of Myocardial Infarction

Arrhythmias: Irregular heart rhythms caused by damage to the heart's electrical system.
Cardiogenic Shock: Heart unable to pump enough blood to meet the body's needs, leading to organ failure and requiring immediate medical intervention.
Myocardial Rupture: Weakened heart wall can rupture, causing life-threatening internal bleeding.
Pericarditis: Inflammation of the pericardium (sac surrounding the heart), causing chest pain and fluid buildup.
Thromboembolism: Blood clots may form in the heart and travel to other parts of the body, causing strokes or blockages.
Ventricular Aneurysm: Weakened area of the heart wall can bulge outward, potentially leading to heart failure or arrhythmias.
Recurrent Myocardial Infarction: Increased risk of future heart attacks after experiencing one.
Psychological Complications: Patients may experience anxiety, depression, or PTSD following a heart attack, affecting their recovery.

Acute Pericarditis vs Pericardial Effusion

Acute Pericarditis: Inflammation of the pericardium.
- Causes: Viral infections, bacterial infections, post-myocardial infarction, autoimmune diseases, trauma, surgery, medications.
- Symptoms: Sharp, pleuritic chest pain (worsens with deep breathing or coughing), relieved by leaning forward, fever, pericardial friction rub (sound of inflamed layers rubbing).
- Diagnosis: Clinical history, physical exam, electrocardiogram (ECG).
Pericardial Effusion: Fluid accumulation in the pericardial sac.
- Causes: Can be caused by acute pericarditis, heart failure, infections, cancer.
- Symptoms: Chest pain, shortness of breath, palpitations, swelling in the legs and ankles.
- Diagnosis: Cardiac ultrasound, chest X-ray.

Poor Feeding in Infants

Infants may refuse to eat or drink due to difficulty breathing or fatigue.

Croup Clinical Manifestations

Barking Cough: A distinctive seal-like or barking cough, often alarming to parents.
Stridor: High-pitched, wheezing sound during inhalation, indicates narrowing of the upper airway.
Hoarseness: Hoarse voice due to laryngeal involvement.
Respiratory Distress:
- Rapid breathing (tachypnea)
- Retractions (indrawing of the chest wall)
- Nasal flaring
Fever: Mild to moderate fever, usually below 102°F (39°C).
Symptoms of Upper Respiratory Infection: Runny nose, congestion, mild sore throat.
Agitation or Anxiety: Children may become anxious due to difficulty breathing.
Cyanosis (in severe cases): Bluish discoloration of the lips or face, indicating significant respiratory distress.
Diminished Breath Sounds (in severe cases): Breath sounds may be diminished due to significant airway obstruction.

Croup Severity Classification

Mild Croup: Barking cough, no stridor at rest, no respiratory distress.
Moderate Croup: Barking cough, stridor at rest, some respiratory distress.
Severe Croup: Barking cough, stridor at rest, significant respiratory distress, possible cyanosis.

Causes of Cirrhosis

Chronic Alcohol Abuse: Prolonged excessive alcohol consumption leads to alcoholic liver disease, progressing to cirrhosis overtime.
Chronic Viral Hepatitis: Viral infections like hepatitis B can cause chronic liver disease leading to cirrhosis.

Causes of GERD

Weak Lower Esophageal Sphincter (LES): Relaxed LES allows stomach acid to flow back up into the esophagus.
Hiatal Hernia: Part of the stomach protrudes through the diaphragm, impairing LES function.
Increased Stomach Acid Production: Excessive stomach acid increases likelihood of reflux.
Delayed Gastric Emptying: Slow emptying of the stomach can lead to increased pressure and reflux, commonly seen in conditions like gastroparesis.
Stress: While not a primary cause, stress can worsen GERD symptoms.
Age: Older adults may have weakened LES function and increased risk factors for GERD.
Medications: Certain medications can relax the LES or irritate the esophagus (e.g., antihistamines, calcium channel blockers, sedatives, NSAIDs).

Clinical Manifestations of Appendicitis

Abdominal Pain: Begins around the umbilicus (navel), then shifts to the right lower quadrant (RLQ) of the abdomen (McBurney's point).
Nausea and Vomiting: Often occurs after the onset of abdominal pain.
Loss of Appetite: Sudden decrease in hunger often precedes or accompanies pain.
Fever: Low-grade fever (99°F to 102°F), typically develops with inflammation.
Constipation or Diarrhea: More common to experience constipation, though diarrhea may also occur.
Abdominal Tenderness: Physical exam often shows tenderness in the RLQ, rebound tenderness or guarding indicates irritation of the peritoneum.
Changes in Bowel Habits: Changes in regular bowel habits, related to underlying inflammation.
Pain with Movement: Worsened pain with coughing, walking, jarring movements.
Psoas and Obturator Signs:
- Psoas sign: Pain when the hip flexed against resistance.
- Obturator sign: Pain when the hip flexed and rotated inward.

Transmission of Hepatitis A, B, and C

Hepatitis A:
- Fecal-Oral Route: Primary transmission through consuming contaminated food or water.

Hypoxemia Symptoms

Fatigue: Weakness and tiredness.
Shortness of Breath: Difficulty breathing.
Cyanosis: Bluish discoloration of skin or lips, indicating low oxygen level.
Clubbing: Abnormal widening of the fingertips, observed in chronic hypoxemia.
Dizziness and Lightheadedness: Insufficient oxygen delivered to the brain, especially when standing up quickly.
Headaches: Reduced oxygen levels in the brain can cause headaches.
Cold Extremities: Decreased peripheral blood flow due to body prioritizing oxygen to vital organs.

Compensatory Mechanisms for Hypoxemia

Increased Heart Rate (Tachycardia): To enhance cardiac output and improve oxygen delivery.
Increased Cardiac Output: To pump more blood and deliver oxygen.
Increased Respiratory Rate: To increase oxygen uptake and eliminate carbon dioxide.
Redistribution of Blood Flow: Blood directed from less essential organs to vital organs to maintain oxygen.
Erythropoiesis: Kidneys release erythropoietin (EPO) to stimulate red blood cell production in bone marrow, taking weeks to fully develop.
Increased 2,3-Bisphosphoglycerate (2,3-BPG): Enhanced production in red blood cells to facilitate oxygen release from hemoglobin, improving oxygenation despite low hemoglobin levels.

Types of Anemia: Pernicious, Hemolytic, Sickle Cell

Pernicious Anemia:
- Definition: Macrocytic anemia caused by vitamin B12 deficiency due to malabsorption.
- Causes: Autoimmune gastritis, destruction of gastric parietal cells leading to lack of intrinsic factor required for absorption, surgery removing parts of stomach or intestines, strict vegetarian/vegan diet without B12 supplementation.
- Pathophysiology: Without B12, red blood cell production is impaired, leading to large dysfunctional RBCs.
Hemolytic Anemia:
- Definition: Premature destruction of red blood cells.
- Causes: Genetic disorders (e.g., sickle cell anemia), autoimmune diseases, infections, medications, blood transfusions.
- Pathophysiology: Abnormal red blood cells may be destroyed by the body's immune system, leading to anemia.
Sickle Cell Anemia:
- Definition: Inherited blood disorder causing sickle-shaped, fragile red blood cells which can block blood flow.
- Causes: Genetic inheritance of defective hemoglobin gene.
- Pathophysiology: Abnormal red blood cells lack flexibility, getting trapped in blood vessels causing blockages and pain.
