    Study Notes

    Cardiovascular Conditions Overview

    • Main focus includes Coronary Artery Disease, Acute Coronary Syndromes, Stable Angina, Heart Failure, and Sickle Cell Disease.
    • Objective is to describe key conditions, their signs, symptoms, and management strategies.

    Risk Factors for Coronary Artery Disease

    • Heredity: Family history significantly contributes to risk.
    • Obesity and Sedentary Lifestyle: Both are modifiable risk factors.
    • Gender: Males are generally more susceptible; women's risk increases post-menopause.
    • Diet: High intake of refined carbohydrates, saturated fats, and cholesterol raises risk.
    • Age: Increasing age correlates with higher risk.
    • Smoking and Alcohol: Both habits are significant risk factors.
    • Diabetes Mellitus and Hypertension: These conditions contribute to increased risk.
    • Emotional Stress: Excessive stress is a recognized factor.

    Atherosclerosis

    • Accumulation of cholesterol in the tunica media leads to plaque formation.
    • White blood cells form a fibrous cap around this plaque.
    • Plaque rupture can result in blockage elsewhere, causing ischemia or infarction.

    Stable Angina (Angina Pectoris)

    • Ischaemic chest pain arises from reduced blood supply to the myocardium.
    • Triggered by emotional stress or exertion, presenting with:
      • Chest discomfort characterized by pain, tightness, or indigestion.
      • Possible radiation to back, arms, neck, or jaw.
      • Relief often occurs with rest or nitrates.

    Management of Stable Angina

    • Implement DR ABCDE protocol.
    • Provide rest to decrease heart workload.
    • Administer analgesia (Entonox) if needed.
    • Monitor with an ECG.

    Heart Failure

    • Defined as an abnormality in cardiac structure/function, leading to inadequate oxygen delivery.
    • Can be categorized as acute or chronic, and right-sided, left-sided, or both.
    • Cardiac output is influenced by stroke volume, heart rate, preload, contractility, and afterload.

    Signs and Symptoms of Heart Failure

    • Common symptoms include fatigue, dyspnoea, and congestion.
    • Patients may experience breathlessness while lying down.

    Management of Heart Failure

    • Follow DR ABCDE guidelines.
    • Keep the patient at rest and monitor vital signs.
    • Administer oxygen to maintain saturation above 94%.
    • Conduct an ECG for further assessment.

    Acute Coronary Syndrome (ACS)

    • ACS encompasses unstable angina, NSTEMI, and STEMI.
    • Results from reduced blood flow leading to ischaemia and potential infarction, mainly affecting the left ventricle.

    Symptoms of ACS

    • Chest pain: Heavy, squeezing, or crushing.
    • Radiating pain to arms, jaw, or neck.
    • Accompanying symptoms may include nausea, sweating, pallor, and feelings of impending doom.
    • Atypical presentations (e.g., shortness of breath) may occur, especially in specific demographics.

    Management of ACS

    • Perform a 12 lead ECG immediately.
    • Address major airway, breathing, and circulation problems.
    • Administer medications according to local practice guidelines.
    • Provide oxygen for saturation below 94% and ensure rapid transport to a hospital.

    Sickle Cell Disease

    • A hereditary condition affecting haemoglobin, resulting in sickle-shaped red blood cells under deoxygenated conditions.
    • Deformed cells hinder movement through blood vessels, leading to ischemia.

    Sickle Cell Crisis

    • Early breakdown of sickle cells leads to reduced lifespan and anemia.
    • Symptoms include severe joint pain, difficulty breathing, jaundice, dehydration, hypotension, tachycardia, and altered level of consciousness.

    Assessment & Management of Sickle Cell Crisis

    • Use ABCD assessment method.
    • Check if the patient has an individualized treatment plan.
