Study Notes
Cardiovascular Conditions Overview
- Major cardiovascular disorders include Coronary Artery Disease, Acute Coronary Syndromes, Stable Angina, Heart Failure, and Sickle Cell Disease.
- Recognizing symptoms and effective management strategies is imperative for optimal patient care.
Coronary Artery Disease Risk Factors
- Heredity: Family history increases risk.
- Obesity: Associated with higher risk.
- Gender: Males are at greater risk until menopause, when females' risk increases.
- Diet: High in refined carbohydrates, saturated fats, and cholesterol is harmful.
- Age: Risk increases with age.
- Lifestyle Factors: Smoking, high cholesterol (LDL), sedentary lifestyle, excessive alcohol consumption, and high blood pressure are modifiable risk factors.
- Diabetes Mellitus: Significantly increases risk.
- Emotional Stress: Contributes to cardiovascular issues.
Atherosclerosis
- Formation occurs when cholesterol lodges in the tunica media, leading to inflammation and fibrous cap development.
- This process narrows coronary arteries, resulting in reduced blood flow (ischemia) or complete obstruction (infarction).
Stable Angina (Angina Pectoris)
- Characterized by ischemic chest pain due to decreased blood supply to the myocardium, primarily from CAD.
- Symptoms can radiate to the back, arms, neck, jaw, and can be provoked by stress or exertion but typically resolve with rest.
Symptoms of Stable Angina
- Classic pain or discomfort in the chest.
- Possible radiating pain and belching.
- Relieved by rest and/or nitrates.
Management of Stable Angina
- Follow DR ABCDE protocol:
- D: Danger - assess situation
- R: Rest - place the patient at rest
- A: Airway – ensure it is clear
- B: Breathing – assess breathing
- C: Circulation – monitor circulation
- D: Disability – check for neurological issues
- E: Exposure – assess for other injuries.
Heart Failure
- Results from abnormal cardiac structure or function; the heart fails to deliver sufficient oxygen.
- Can be classified as acute or chronic and may affect the right side, left side, or both sides.
- Cardiac output is determined by stroke volume and heart rate.
Key Concepts in Heart Failure
- Preload: Blood volume stretching the heart muscle at the end of diastole.
- Contractility: Strength of the heart's contraction.
- Afterload: Pressure needed for the left ventricle to eject blood.
Common Symptoms of Heart Failure
- Fatigue and exercise intolerance.
- Dyspnoea and orthopnoea (difficulty breathing while lying down).
- Congestion due to fluid build-up.
Management of Heart Failure
- Implement DR ABCDE protocol similar to Angina management.
- Maintain oxygen saturation above 94%.
- Complete a full set of observations.
Acute Coronary Syndrome (ACS)
- Encompasses unstable angina, NSTEMI, and STEMI, characterized by blood flow reduction leading to ischemia and potential tissue death.
Symptoms of ACS
- Chest pain that is heavy, squeezing, or crushing, sometimes radiating to arms, jaw, or back.
- Other symptoms may include nausea, sweating, and shortness of breath.
- Atypical presentations may occur, particularly in younger patients, diabetics, and women.
Management of ACS
- Perform a 12-lead ECG promptly.
- Address any life-threatening conditions following local protocols.
- Administer oxygen and ensure rapid transport to a hospital.
Sickle Cell Disease
- A hereditary condition affecting hemoglobin, leading to sickle-shaped red blood cells that obstruct blood vessels, causing ischemia.
Sickle Cell Trait vs. Disease
- Trait: One sickle cell gene; generally asymptomatic.
- Disease: Both genes present, leads to sickle-shaped RBCs and associated complications.
Sickle Cell Crisis
- Occurs when sickle cells clump together, obstructing blood flow.
- Signs include severe pain (especially in joints), breathing difficulties, and possible jaundice or fever.
Management of Sickle Cell Crisis
- Initial assessment via ABCD approach; review the patient's individual treatment plan.
