Study Notes
Cardiovascular Conditions Overview
- Primary focus: understanding disorders of the cardiovascular system, including main conditions, signs, symptoms, and management approaches.
- Key conditions covered: Coronary Artery Disease, Acute Coronary Syndromes, Stable Angina, Heart Failure, and Sickle Cell Disease.
Coronary Artery Disease (CAD)
- Significant risk factors include heredity, obesity, gender, diet (high in refined carbohydrates and fats), age, smoking, diabetes, emotional stress, hypertension, sedentary lifestyle, high LDL cholesterol, and excessive alcohol consumption.
- Modifiable risk factors highlighted in red for emphasis.
Atherosclerosis
- Involves cholesterol accumulation in the tunica media leading to plaque formation.
- Plaque can rupture, causing obstructions and resulting in ischaemia (reduced blood flow) or infarction (complete obstruction).
Stable Angina (Angina Pectoris)
- Characterized by ischemic chest pain due to diminished blood supply to the myocardium caused by CAD.
- Pain occurs during exertion or emotional stress but not at rest.
- Symptoms include classic chest discomfort, radiating pain, possible belching, relief upon rest or nitrates.
Management of Stable Angina
- Implement a DR ABCDE approach (assess, treat airway, breathing, circulation, disability, expose).
- Ensure patient rest to reduce heart workload.
- Administer analgesia and perform ECG to monitor heart activity.
Heart Failure
- Defined as an inability of the heart to meet the body's oxygen demands, can be acute or chronic.
- Can affect right side, left side, or both, leading to decreased cardiac output.
- Cardiac output determined by stroke volume and heart rate; stroke volume affected by preload, contractility, and afterload.
Signs and Symptoms of Heart Failure
- Common symptoms across all types include fatigue, dyspnoea, congestion, and breathlessness when lying down.
Management of Heart Failure
- Utilize the DR ABCDE approach, ensure patient rest, monitor vital signs, provide oxygen to maintain saturation above 94%, and perform ECG.
Acute Coronary Syndrome (ACS)
- Encompasses conditions like unstable angina, NSTEMI, and STEMI.
- Caused by blockage in coronary arteries leading to ischaemia and possible infarction with irreversible cardiac muscle damage.
Common Symptoms of ACS
- Includes chest pain described as heavy or tight, pain radiating to arms, jaw, neck, and back, nausea, vomiting, shortness of breath, clamminess, and feelings of impending doom.
Atypical Presentations of ACS
- Common in specific populations: younger adults, elderly, unwell diabetics, and women; may present without typical chest pain.
Management of Acute Coronary Syndrome
- Immediate 12-lead ECG and correction of major issues (ABC problems).
- Administer oxygen if saturation is below 94%, and transport to the appropriate hospital.
Sickle Cell Disease
- An inherited condition affecting haemoglobin; deoxygenated haemoglobin leads to sickle-shaped red blood cells causing blockages and ischaemia.
- Distinction between sickle cell trait (generally asymptomatic) and sickle cell disease (causing early cell breakdown and anaemia).
Sickle Cell Crisis
- Identified through severe pain, respiratory difficulties, jaundice, fever, dehydration, hypotension, tachycardia, and altered level of consciousness.
Assessment and Management of Sickle Cell Crisis
- Focus on ABCD assessment and check if the patient has an individualized treatment plan to guide management.
