Study Notes
Cardiovascular Diseases (CVDs)
- CVDs encompass various disorders affecting the heart and blood vessels.
- These conditions include coronary artery disease (CAD), heart failure, stroke, hypertension, and peripheral artery disease.
- CVDs are a leading cause of global death, significantly impacting morbidity, mortality, and healthcare costs.
- Globally, CVDs account for approximately 17.9 million deaths annually, representing 32% of all global deaths (WHO).
Epidemiology
- CVD risk factors vary globally and are influenced by lifestyle choices, genetics, and environmental factors.
- CVD incidence increases with age, being more prevalent in men earlier in life but becoming more common in women after menopause.
Types of Cardiovascular Diseases
- Coronary Artery Disease (CAD): Narrowing of coronary arteries supplying oxygen-rich blood to the heart.
- Stroke: Sudden interruption of blood supply to the brain, leading to ischemia and potential brain damage.
- Heart Failure: Inefficient pumping of blood by the heart to meet the body's needs.
- Hypertension (High Blood Pressure): Consistently high blood pressure within arteries, increasing the heart's workload and other CVD risks.
- Peripheral Artery Disease (PAD): Blockage of arteries supplying the limbs, especially the legs, leading to poor circulation.
Pathophysiology of CVDs
- Atherosclerosis: A buildup of fatty deposits (plaque) inside arteries, reducing blood flow.
- Atherosclerosis begins with endothelial dysfunction, allowing lipids to accumulate in the arterial walls, followed by inflammation and plaque formation.
- Plaque growth can block the artery entirely or rupture, leading to thrombosis (clot formation), heart attacks, or strokes.
Risk Factors
- Non-modifiable: Age, gender (men initially at higher risk but women's risk increases post menopause), family history (genetic predisposition), and ethnicity (some ethnic groups have higher risks for certain conditions like hypertension).
- Modifiable: Smoking, unhealthy diet (high in saturated and trans fats, sodium), physical inactivity (leading to obesity), obesity (especially abdominal), high cholesterol, hypertension, and diabetes.
Symptoms of CVDs
- Chest pain (angina): Often during physical exertion, indicating ischemia.
- Shortness of breath: Frequently associated with heart failure or valve problems.
- Palpitations: Irregular heartbeats, possibly symptomatic of arrhythmias.
- Dizziness or fainting (syncope): Can occur in heart rhythm disorders or severe heart failure.
- Leg pain (claudication): May be seen in peripheral artery disease.
Diagnosis of CVDs
- History and physical examination: Detailed clinical history for symptoms, lifestyle, and risk factors.
- Electrocardiogram (ECG): Measures heart's electrical activity to detect issues like arrhythmias, heart attacks, or ischemia.
- Echocardiogram: Ultrasound imaging assessing the heart's structure and function.
- Stress tests: Evaluating heart function under physical exertion.
- Coronary angiography: Imaging technique for detecting coronary artery blockages.
- Blood tests: Measuring markers (like troponins, cholesterol, and glucose) indicative of cardiac health.
Specific Heart Rythm Disorders
- Sinus Arrhythmia: Heart rate variation with breathing cycles.
- Sinus Bradycardia: Slow sinus heart rate (under 60 bpm).
- Sinus Tachycardia: Fast sinus heart rate (over 100 bpm).
Management and Treatment
- Lifestyle modifications: Encouraging a heart-healthy diet, regular physical activity, smoking cessation, and maintaining a healthy weight.
- Medications: Antiplatelets (e.g., aspirin) to reduce clot formation, statins to lower cholesterol, antihypertensives to control blood pressure, beta-blockers and ACE inhibitors to manage heart failure or prevent recurrent heart attacks.
- Surgical interventions: For severe cases, coronary artery bypass grafting (CABG), angioplasty, or implantable devices (pacemakers, defibrillators).
Prevention of CVDs
- Primary prevention: Reducing risk factors in healthy individuals (promoting physical activity, balanced diet).
- Secondary prevention: Preventing recurrence in individuals with prior cardiovascular events (more aggressive management of risk factors).
Global Burden and Challenges
- CVDs have significant socioeconomic impacts, especially in low- and middle-income countries where healthcare access might be restricted.
- The rise in CVDs correlates with factors like urbanization, sedentary lifestyles, and poor dietary choices.
- There’s an urgent need for public health policies, focused on education, prevention, and improved healthcare access to reduce CVD prevalence.
