Heart Disease

What is Heart Disease?

Heart disease, also known as cardiovascular disease (CVD), encompasses a range of conditions that affect the heart and blood vessels. It primarily involves narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina), or stroke. However, heart disease also includes conditions that affect the heart's muscles, valves, or rhythm.

How common is heart disease?

Heart disease is the leading cause of death in the United States. In 2024, cardiovascular disease claimed 931,578 lives in the United States, marking a small rise from the previous year. This elevated the age-adjusted death rate for cardiovascular disease to 233.3 per 100,000 people, reflecting a 4% increase. This upward trend is likely influenced by factors such as lifestyle changes, aging demographics, and potentially lingering effects from the COVID-19 pandemic, which heightened the risk of heart-related complications. Public health efforts are increasingly focusing on early detection, preventive measures, and lifestyle modifications to mitigate the risk factors associated with cardiovascular disease.

Types of Heart Disease:

1. Coronary Artery Disease (CAD): 

The most common type, caused by the buildup of plaque (fatty deposits) in the arteries that supply blood to the heart. This buildup narrows the arteries, limiting blood flow and potentially leading to heart attacks.

2. Congenital Heart Disease:

Congenital heart disease (CHD) includes a wide range of structural heart abnormalities present from birth, each affecting the heart's function differently. Key types of congenital heart defects are:

Atypical heart valves: Valves may not open fully, or they might leak, leading to improper blood flow.

Septal defects: A hole in the wall separating the heart's chambers allows blood to mix between them.

Atresia: A condition where one of the heart's valves is missing, which disrupts normal blood flow.

More severe forms of CHD may involve complex structural issues, like the absence of a ventricle or abnormal connections between major arteries.

According to the American Heart Association (AHA), heart murmurs—a common sign of blood flow irregularity—often occur in children. However, not all murmurs indicate a heart defect, as many are benign and harmless.

3. Arrhythmias: 

These are irregular heartbeats, such as atrial fibrillation, that can interfere with the heart’s ability to pump blood effectively. Arrhythmia refers to an irregular heartbeat. It occurs when the electrical impulses that coordinate the heartbeat do not function correctly. As a result, the heart may beat too quickly, too slowly, or erratically.

There are various types of arrhythmias, including:

Tachycardia: A rapid heartbeat.

Bradycardia: A slow heartbeat.

Premature contractions: Early heartbeats.

Atrial fibrillation: A type of irregular heartbeat.

4. Heart Valve Disease: 

Problems with one or more of the heart’s four valves, which regulate blood flow through the heart, can lead to conditions like stenosis (narrowing) or regurgitation (leaking).

5. Cardiomyopathy: 

A condition where the heart muscle becomes enlarged or rigid, often leading to heart failure. In dilated cardiomyopathy, the heart muscle stretches and thins, causing the heart chambers to dilate. While toxins, arrhythmias, and previous heart attacks are the most common causes, genetics may also play a role. As a result, the heart becomes weaker and is unable to pump blood effectively. This can lead to heart failure, blood clots in the heart, and arrhythmias. It typically affects individuals between the ages of 20 and 60, according to the American Heart Association (AHA).

6. Heart Failure: 

When someone has heart failure, their heart continues to work, but it doesn't function as effectively as it should. Congestive heart failure, a specific form of heart failure, can result from issues with the heart's pumping or relaxing abilities.

Heart failure can arise from untreated coronary artery disease, high blood pressure, arrhythmias, and other underlying conditions that interfere with the heart's capacity to pump or relax properly.

While heart failure can be life-threatening, early intervention for heart-related conditions can help prevent serious complications.

7. Myocardial infarction:

Myocardial infarction, commonly known as a heart attack, occurs when blood flow to the heart is blocked, potentially damaging or destroying part of the heart muscle. The most frequent cause of a heart attack is the buildup of plaque, a blood clot, or a combination of both in a coronary artery. It can also happen if an artery suddenly narrows or experiences a spasm.

8. Mitral Valve Prolapse:

Mitral valve prolapse occurs when the flaps of the mitral valve do not close properly and bulge into the left atrium. This can lead to a heart murmur. While mitral valve prolapse is typically not life-threatening, some individuals may require treatment. The condition is often caused by genetic factors or connective tissue disorders and affects approximately 2% of the population.

9. Aortic Stenosis:

Aortic stenosis occurs when the aortic valve becomes thickened or fused, preventing it from opening properly. This makes it difficult for the heart to pump blood from the left ventricle into the aorta. The condition can be present from birth due to congenital valve abnormalities, or it may develop later in life as a result of calcium buildup or scarring.

10. Mitral Valve Regurgitation:

This condition happens when the mitral valve in the heart doesn't close properly, allowing blood to leak back into the heart. As a result, blood flow through the heart and body becomes less efficient, causing pressure to build up in the heart chambers. Over time, this can lead to heart enlargement and potentially heart failure.

Causes and Risk Factors:

Heart disease can result from a combination of genetic factors and lifestyle choices. Major risk factors include high blood pressure, high cholesterol, diabetes, smoking, obesity, and sedentary lifestyles. Some individuals may have a genetic predisposition to heart disease, which increases their risk regardless of lifestyle.

Symptoms:

Heart disease symptoms can vary depending on the underlying condition. Symptoms may include:

1. Chest pain or discomfort (angina).

2. Shortness of breath.

3. Fatigue.

4. Swelling in the legs, ankles, or feet.

5. Irregular heartbeats.

6. Pounding or racing heart (palpitations).

7. Sweating. 

8. Lightheadedness. 

9. Dizziness or sudden unexplained loss of consciousness. 

10. Chest or upper body pain, pressure, heaviness or discomfort. 

11. Neck pain. 

12. Heartburn or indigestion. 

13. Nausea or vomiting. 

14. Swelling in your lower body.

15. Exhaustion. 

16. Difficulty sleeping. 

17. Inability to handle exercise. 

18. Fever.

Who is at a higher risk of heart disease?

The likelihood of developing heart disease can be influenced by a combination of genetic, lifestyle, and environmental factors. Individuals at higher risk include:

1. Older adults: 

The risk increases with age, especially after 45 for men and 55 for women.

2. Men: 

Generally, men have a higher risk at a younger age compared to women, though the risk for women increases after menopause.

3. Those with a family history of heart disease: 

If your close relatives had heart disease, especially at an early age, you may be more likely to develop it as well.

4. People with certain ethnic backgrounds: 

African Americans, Hispanics, Native Americans, and certain other groups are more prone to heart disease.

5. Individuals with unhealthy lifestyles: This includes those who:

▪️Eat a poor diet (high in unhealthy fats, refined carbs, and salt).

▪️Are physically inactive.

▪️Smoke or are regularly exposed to secondhand smoke.

▪️Drink alcohol excessively.

▪️Experience chronic stress.

6. People with existing health conditions: 

▪️High blood pressure or high cholesterol.

▪️Diabetes or obesity.

▪️Chronic kidney disease, autoimmune diseases, or metabolic syndrome.

7. High cholesterol:

Elevated cholesterol levels raise the risk of atherosclerosis, a condition associated with an increased likelihood of heart attacks and strokes.

8.Obesity: 

Carrying excess weight often aggravates other risk factors for heart disease, such as high blood pressure and cholesterol. In addition, obesity can contribute to the development of type 2 diabetes, which further increases the risk of cardiovascular complications. Maintaining a healthy weight through diet and exercise is essential for reducing these associated risks.

9. Physical Inactivity: 

Leading a sedentary lifestyle is linked to various forms of heart disease and several contributing risk factors. Regular physical activity can help manage blood pressure, reduce cholesterol levels, and support weight management, all of which are important for heart health.

10. Poor Dental Health: 

Unhealthy teeth and gums can allow harmful bacteria to enter the bloodstream, where they may reach the heart and lead to an infection known as endocarditis. Research suggests that oral health is closely connected to heart health, as infections in the gums can contribute to inflammation that affects the cardiovascular system. Maintaining good oral hygiene by brushing and flossing daily, along with regular dental checkups, is essential for both dental and heart health.

The combination of these factors increases the likelihood of developing heart disease, but many risks can be managed or mitigated with lifestyle changes and medical interventions.

Complications

Potential complications of heart disease include:

1. Heart Failure: 

A common complication where the heart is unable to pump enough blood to meet the body's demands.

2. Heart Attack: 

Occurs when a piece of plaque or a blood clot blocks an artery supplying the heart, cutting off blood flow.

3. Stroke: 

The risk factors for heart disease, such as narrowed or blocked arteries, can also lead to an ischemic stroke, where insufficient blood reaches the brain.

4. Aneurysm: 

A bulging artery wall that can rupture, causing life-threatening internal bleeding.

5. Peripheral Artery Disease: 

This condition, often caused by atherosclerosis, results in poor blood circulation to the arms or legs, leading to symptoms like leg pain (claudication), especially when walking.

6. Sudden Cardiac Arrest: 

The sudden cessation of heart activity, breathing, and consciousness, usually due to a malfunction in the heart's electrical system. It is a medical emergency that, if not treated immediately, can lead to sudden cardiac death.

What tests are done to diagnose heart disease?

Tests used to diagnose different types of heart disease include:

▪️Electrocardiogram (EKG or ECG)

▪️Ambulatory monitors

▪️Echocardiogram (Echo)

▪️Cardiac computerized tomography (CT)
