Understanding Heart Disease
Heart disease is the leading cause of death for both men and women in the United States. It is a condition that affects the heart and blood vessels. Heart disease can lead to a heart attack, which occurs when blood flow to the heart is blocked.
There are many different types of heart disease, but the most common type is coronary artery disease (CAD). CAD occurs when the arteries that supply blood to the heart become narrowed or blocked by plaque. Plaque is a buildup of cholesterol, fat, calcium, and other substances.

- Age: The risk of heart disease increases with age.
- Sex: Men are more likely to develop heart disease than women.
- Family history: A family history of heart disease increases your risk.
- Race: African Americans are more likely to develop heart disease than whites.
- High blood pressure: High blood pressure is a major risk factor for heart disease.
- High cholesterol: High cholesterol levels can increase your risk of heart disease.
- Diabetes: Diabetes is a major risk factor for heart disease.
- Obesity: Obesity is a major risk factor for heart disease.
- Smoking: Smoking is a major risk factor for heart disease.
- Physical inactivity: Physical inactivity is a major risk factor for heart disease.
- Unhealthy diet: A diet high in saturated fat, cholesterol, and sodium can increase your risk of heart disease.
Symptoms of Heart Disease
The symptoms of heart disease can vary depending on the type of heart disease. Some common symptoms include:

- Blood tests: Blood tests can measure your cholesterol levels, blood sugar levels, and other factors that can increase your risk of heart disease.
- Electrocardiogram (ECG): An ECG is a test that measures the electrical activity of your heart. It can help your doctor identify heart rhythm problems and other signs of heart disease.
- Echocardiogram: An echocardiogram is a test that uses sound waves to create images of your heart. It can help your doctor assess the structure and function of your heart.
- Cardiac catheterization: Cardiac catheterization is a test that involves inserting a thin tube into your heart. It can help your doctor identify blockages in your arteries and other heart problems.
Treatment for Heart Disease
The treatment for heart disease depends on the type of heart disease and the severity of the condition. Treatment options may include:
- Medications: Medications can be used to lower blood pressure, reduce cholesterol levels, prevent blood clots, and improve heart function.
- Lifestyle changes: Lifestyle changes, such as eating a healthy diet, getting regular exercise, and quitting smoking, can help reduce your risk of heart disease and improve your overall health.
- Surgery: Surgery may be necessary to repair or replace damaged heart valves or arteries.
Prevention of Heart Disease
