Heart Disease Guide

What is Heart Disease?

Heart disease refers to a range of cardiovascular conditions that affect the structure and function of the heart. It can involve blood vessel diseases, heart rhythm problems, and congenital heart defects, among others. These conditions can lead to complications like heart attacks, heart failure, and strokes, requiring proper management and treatment.

Classification of Heart Disease

Illness: Heart disease is classified as a chronic medical condition affecting the cardiovascular system. It encompasses a variety of disorders that impact the heart’s ability to function efficiently.

Heart Disease Statistics

Heart disease is the leading cause of death worldwide, responsible for over 18 million deaths annually. In the United States, approximately 1 in 4 deaths is attributed to heart disease, with an increasing prevalence in low- and middle-income countries.

Types of Heart Disease

1. Coronary Artery Disease (CAD): Blockage of arteries supplying the heart.
2. Heart Arrhythmias: Irregular heart rhythms, such as atrial fibrillation.
3. Heart Valve Disease: Malfunctioning heart valves.
4. Congenital Heart Defects: Structural heart abnormalities present at birth.
5. Cardiomyopathy: Weakened or thickened heart muscle.
6. Heart Failure: The heart’s inability to pump blood effectively.
7. Peripheral Artery Disease (PAD): Narrowing of arteries in the extremities.

Health Signs and Symptoms

Early Detection: Symptoms often develop gradually, so early recognition is key.

Common Signs and Symptoms:

• Chest pain or discomfort (angina)
• Shortness of breath
• Fatigue and weakness
• Swelling in the legs, ankles, or feet
• Irregular heartbeat (palpitations)
• Dizziness or fainting
• Pain in the neck, jaw, or back

Anatomy and Physiology

Affected Body Parts:

• Heart: The primary organ affected, including its muscles, valves, and electrical system.
• Blood Vessels: Arteries, veins, and capillaries that supply blood to the heart and body.
• Lungs: May be impacted in cases of heart failure or pulmonary hypertension.

Causes

Heart disease is caused by a combination of genetic, lifestyle, and environmental factors.

Common Causes:

1. Atherosclerosis: Plaque buildup in arteries.
2. Hypertension: High blood pressure damages blood vessels.
3. Smoking: Increases risk of coronary artery disease.
4. Diabetes: Contributes to blood vessel damage.
5. Obesity: Increases strain on the heart.
6. Sedentary Lifestyle: Weakens the cardiovascular system.
7. Genetics: Family history of heart disease.

Heart Disease Stages

1. Stage A (At Risk): No symptoms but risk factors are present.
2. Stage B (Asymptomatic): Structural heart disease without symptoms.
3. Stage C (Symptomatic): Structural damage with symptoms like fatigue or chest pain.
4. Stage D (Advanced): Severe symptoms and limited heart function.

Prevention

• Maintain a heart-healthy diet (low in sodium, trans fats, and cholesterol).
• Exercise regularly (at least 150 minutes of moderate activity per week).
• Avoid smoking and limit alcohol consumption.
• Manage stress with relaxation techniques.
• Regularly monitor blood pressure, cholesterol, and blood sugar levels.

Heart Disease Diagnosis

Diagnosis is based on medical history, physical examination, and diagnostic tests to assess heart function and detect abnormalities.

Tests & Examinations

1. Electrocardiogram (ECG): Records the heart’s electrical activity.
2. Echocardiogram: Uses ultrasound to create heart images.
3. Stress Tests: Measures heart function under physical exertion.
4. Blood Tests: Checks for markers like cholesterol and troponin.
5. Coronary Angiography: Uses X-rays to view blood flow in the arteries.

Health Professionals

1. Cardiologists: Specialists in heart diseases.
2. Cardiothoracic Surgeons: Perform surgical interventions.
3. Primary Care Physicians: Manage risk factors and coordinate care.
4. Dietitians: Provide dietary advice to reduce risk.
5. Rehabilitation Specialists: Assist with post-heart attack recovery.
