Study Notes
Cardiovascular Disease
- Types: Coronary heart disease, Cerebrovascular disease, Peripheral vascular disease, Deep vein thrombosis, Valvular heart disease, Congenital heart disease.
- Risk Factors: Smoking, physical stress on organs, chronically elevated blood glucose levels.
Atherosclerosis
- A common disorder that narrows arteries due to plaque buildup.
- Limits the flow of oxygen-rich blood to organs.
- Often has no symptoms, making it a "silent killer."
-
Stages:
- Fatty Streak: Lipids build up beneath damaged endothelium.
- Plaque Progression: Plaque grows into the lumen, limiting blood flow.
- Plaque Disruption: Plaque thickens fibrous capsules, further narrowing the artery.
-
Complications:
- Thrombosis: Plaque blocks the artery.
- Infarction: Poor blood flow leads to tissue death.
- Angina, myocardial infarction (heart attack), peripheral heart disease, and Ischemic heart disease.
Ischemic Heart Disease
- Restriction of blood supply to tissues, potentially damaging the myocardium.
- Can lead to myocardial infarction (heart attack) and death.
-
Causes:
- Atherosclerosis: Chronic reduced blood supply to the myocardium.
- Risk Factors: Age, smoking, hypertension, hyperlipidemia, and diabetes.
Hyperlipidemia
- High blood cholesterol levels, associated with increased risk of atherosclerosis.
- LDL (Low-density lipoproteins): Elevated levels are a major cause of atherosclerosis.
- HDL (High-density lipoproteins): Lower HDL is linked to increased risk.
- Dietary factors: Low fiber diets may increase risk.
Angina Pectoris
- Chest pain caused by narrowing coronary arteries.
- Associated with myocardial ischemia, leading to squeezing or gripping pain in the arm or jaw.
Stable or Unstable Angina
- Angina can be stable or unstable.
- Unstable: Changing pattern, prolonged pain, can lead to myocardial infarction if untreated.
Angina Pectoris - Management
- Relieved by rest or glyceryl trinitrate (GTN), a vasodilator.
- Other medications include aspirin, beta blockers, statins, ACE inhibitors.
- Angioplasty (surgery) may be an option.
Myocardial Infarction (Heart Attack)
- Blockage of a coronary artery.
- Resultant ischemia leads to necrosis (tissue death) of the myocardium.
Myocardial Infarction (Heart Attack) - Symptoms
- 10-20% Silent Infarctions: Women may present with atypical symptoms.
- Symptoms: Severe crushing pain in the left arm, lasting long, sweating, restlessness, confusion.
Myocardial Infarction (Heart Attack) - Management
- Hospital: ECG, blood tests, oxygen, echocardiogram.
- Comfort position
- 300mg of aspirin
- GTN when angina occurs
Myocardial Complications
- Acute: Can include arrhythmias, heart failure, cardiogenic shock.
- Longer term: Can include heart failure, valvular heart disease, pericarditis.
Cardiac Arrest
- Sudden loss of heart function, breathing, and consciousness.
- Difference from heart attack: While a heart attack is a circulation problem, cardiac arrest is an electrical malfunction where the heart stops beating.
- Aims: Provide circulatory support.
- CPR: Needed within 2 minutes.
- AED (Automated External Defibrillator): Used for ventricular fibrillation.
Cardiac Arrest - Management
- Registries: Need to know how to deal with cardiac arrest (CPR cycle)
- BLS (Basic Life Support) Training: Essential for all staff.
- Scenarios and Induction: Training for new staff.
Cardiac Devices
- Pacemakers: Replaces electrical conduction of the heart, causing heart muscle to contract and pump blood.
Cerebrovascular Disease
- Disorders affecting the blood vessels of the brain and cerebral circulation.
- Causes: Stenosis, thrombosis, embolism, and hemorrhage.
- Includes: Cerebrovascular accident (Stroke) and Transient Ischemic Attacks (TIAs).
-
Strokes and TIAs:
- Hemorrhagic Stroke: Intracerebral bleed.
- Ischemic Stroke: Blood clot blocks an artery.
- TIA: Temporary blockage, symptoms resolve quickly.
Peripheral Vascular Disease
- Blood circulation disorder affecting the body (excluding brain and heart), mostly legs and feet.
- Can affect arteries, veins, or lymphatic vessels.
- Symptoms include skin changes, weak pulses, and increased risk of stroke, amputation, and restricted mobility due to pain.
Aortic Aneurysm
- "Balloon-like bulges" in the artery wall.
- Caused by weakness in the arterial wall.
- Can remain silent but carries a risk of rupture leading to life-threatening hemorrhage.
- Causes: Hypertension and atherosclerosis.
- Management: Surgery to prevent rupture.
Orthostatic Hypertension
- Drop in blood pressure when getting up.
- Blood fails to constrict when standing up, leading to dizziness.
- Common in those taking antihypertensive medication, the elderly, and pregnant women.
Congenital Heart Disease
- Heart defects present at birth.
- Cyanotic: Right-to-left shunting, leading to blue skin.
- Acyanotic: Left-to-right shunting, typically asymptomatic.
Valvular Heart Disease
- Damage to heart valves.
- Stenosis: Valve fails to open fully, restricting blood flow.
- Regurgitation: Valve fails to close fully, allowing backflow of blood.
- Prolapse: Valve slips out of place.
Hypertension
- Definition: High blood pressure persistently exceeding 140/90 mmHg.
- A "silent killer," as it often has no symptoms.
- Increased risk of cardiovascular, brain, and kidney diseases.
- Affects people of all ages.
-
Types:
- Primary (Essential): 90-95% of cases, no specific cause.
- Secondary: 5-10% of cases, caused by other medical conditions (e.g., renal disease, medications, other diseases).
- Symptoms: Often asymptomatic.
- Complications: Angina, heart failure, vision loss, kidney diseases, peripheral vascular disease.
- Management: Lifestyle changes (weight loss, quitting smoking), medication (beta blockers, ACE inhibitors, calcium channel blockers).
Vascular Disease (Veins)
- DVT (Deep Vein Thrombosis): Blood clots form in deep veins, often in the legs.
- Causes: Prolonged immobility, surgery, pregnancy, inherited clotting disorders.
- Symptoms: Pain, swelling, redness, warmth in the affected leg.
Variations in Medical Conditions
- Variations in how medical conditions are identified and treated for these cases.
