Study Notes
Hemolytic Anemia and Congestion
- In hemolytic anemia, most oxygenated blood remains in the lungs, hindering the left heart's ability to pump sufficient oxygenated blood to systemic circulation, resulting in hypoxia.
- Congestion of the inferior vena cava impacts lower body circulation; blood accumulates in the liver, causing hepatomegaly.
Chronic Hypoxia and the Renin-Angiotensin-Aldosterone System (RAAS)
- Chronic hypoxia triggers the kidney to release renin, initiating the RAAS cascade.
- The liver produces angiotensinogen, which is converted to angiotensin I in the lungs by ACE.
- Angiotensin II, a vasoconstrictor, increases blood pressure and stimulates aldosterone release from the adrenal cortex.
- RAAS causes hypokalemia and increases blood pressure.
Congestive Heart Failure (CHF) Symptoms
Right-Sided CHF
- Jugular vein distention
- Leg edema
- Portal hypertension
- Severe anemia, possibly from splenomegaly
- Hepatomegaly
- Splenomegaly
- Elevated central venous pressure
- Jaundice (due to liver involvement)
- Internal hemorrhoids
Left-Sided CHF
- Orthopnea (need for multiple pillows to sleep)
- Rales/crackles
- Hypokalemia (due to RAAS activation)
- Hypertension (e.g., 150/100 mmHg)
- Polycythemia (increased RBC due to erythropoietin release in response to hypoxia)
- Clubbing of fingers
- Anorexia, weight loss, weakness (due to decreased metabolism from hypoxia)
- Elevated pulmonary artery pressure
Different Types of Anemia
- Inadequate oxygen supply to tissues is a characteristic of anemia.
SIADH (Syndrome of Inappropriate ADH) and Diabetes Insipidus (DI)
- SIADH is characterized by water retention, leading to dilutional hyponatremia (low serum sodium). Urine is concentrated.
- DI involves water loss, resulting in concentrated blood and dilute urine.
- ADH (vasopressin) in SIADH causes water retention in distal renal tubules and collecting ducts, but not electrolytes.
- The urine specific gravity is an indicator of urine concentration (normal range: 1.010-1.025). High specific gravity indicates concentrated urine.
- In SIADH, urine is concentrated and blood is diluted; In DI, the opposite is true.
Hyperparathyroidism and Hypoparathyroidism
Hyperparathyroidism
- Hypercalcemia
- Muscle cramps (due to hypocalcemia at cellular level)
- Hypophosphatemia
- Increased urine output
- Polydipsia
- Increased risk of bone fractures
- Hypertension
Hypoparathyroidism
- Hypocalcemia
- Dry, scaly skin
- Dry, brittle hair and nails
- Muscle weakness
- Low blood pressure
- Seizures
- Tingling in lips, fingers, and toes
- Positive Chvostek’s sign
- Positive Trousseau’s sign
- Laryngospasm
Cushing’s Disease and Addison’s Disease
Cushing's Disease (Hypercortisolism)
- Anorexia
- Nausea and vomiting
- Muscle weakness
- Fatigue
- Paralysis
- Dysrhythmias
- Renal damage
- Moon face
- Hyperglycemia
- Edema
- Hypertension
- Delayed wound healing
- Thinning scalp hair
- Osteoporosis
- Bradycardia
- Hirsutism
- Obesity in trunk, thin arms and legs
- Purple striae
- Hypocalcemia
Addison’s Disease (Adrenal Insufficiency)
- Hypotension
- Hyponatremia
- Bronze/eternal tan skin
- Dehydration
- Hyperkalemia
- Hypoglycemia
- Loss of appetite
- Fatigue
- Nausea and vomiting
- Depression
- Weight loss
- Muscle weakness
Effects of Adrenal Cortex Hormones
- Mineralocorticoids (like aldosterone): regulate salt balance.
- Sex hormones (estrogen and testosterone): produced by adrenal cortex, even after oophorectomy or hysterectomy.
Cranial Nerves
- The notes mention cranial nerves but do not list all of them or their functions. Only the olfactory nerve is mentioned (CN I).

Description
This quiz explores the complexities of hemolytic anemia and its impact on the heart and systemic circulation. It covers the relationship between chronic hypoxia, the Renin-Angiotensin-Aldosterone System, and symptoms associated with congestive heart failure, particularly right-sided CHF. Test your understanding of these critical cardiovascular pathologies.
