Heart disease is the leading cause of death in the United States, but it is also one of the most preventable.
It refers to a broad range of conditions that affect the heart’s structure and function, from clogged arteries to irregular rhythms.
By understanding what heart disease is, what causes it, and how to detect it early, you can take control of your heart health and reduce your long-term risk.
What Is Heart Disease?
Heart disease, also known as cardiovascular disease, is a general term that describes several disorders affecting the heart and blood vessels. These include coronary artery disease, heart failure, arrhythmias, and congenital heart defects.
The most common form is coronary artery disease (CAD), which occurs when plaque builds up in the arteries that supply blood to the heart.
This reduces oxygen flow and can lead to chest pain, heart attack, or other complications.
Heart disease develops gradually over time, often beginning with damage to the inner lining of the arteries. Once this damage occurs, cholesterol and other materials accumulate and harden into plaque, narrowing the arteries and restricting circulation.
What Causes Heart Disease?
Heart disease is caused by a combination of lifestyle factors, genetics, and underlying medical conditions that damage the cardiovascular system.
Major Risk Factors
- High blood pressure
- High cholesterol
- Smoking
- Diabetes
- Obesity and lack of exercise
- Unhealthy diet high in saturated fats or sodium
- Chronic stress
- Family history of heart disease
- Excessive alcohol use
Many of these factors can be managed through lifestyle changes and regular monitoring, making early screening one of the most powerful tools for prevention.
Common Symptoms
Heart disease can present in many ways depending on the specific condition, but some of the most common symptoms include:
- Chest pain or discomfort (angina)
- Shortness of breath
- Fatigue
- Dizziness or fainting
- Irregular heartbeat
- Swelling in the legs or ankles
It is also possible to have heart disease without any noticeable symptoms, which makes preventive screening even more important.
How to Get Tested for Heart Disease
There are several tests available to evaluate heart health and detect early signs of disease. Many are noninvasive and can be completed quickly with minimal discomfort.
Common Screening Tests
- Blood pressure measurement: Detects hypertension, a major risk factor.
- Cholesterol panel: Measures LDL, HDL, and triglycerides to assess risk for plaque buildup.
- Electrocardiogram (ECG or EKG): Records electrical activity to detect irregular heart rhythms or previous heart damage.
- Echocardiogram: Uses ultrasound to assess heart structure and pumping function.
- Stress test: Evaluates how the heart performs under physical exertion.
- Coronary calcium scan: A CT scan that measures calcium buildup in coronary arteries, indicating potential blockages.
At Atlas Health Screening, our comprehensive heart health assessments combine these tests to identify potential risks early and guide you toward preventive care.
Take Control of Your Heart Health
Heart disease remains one of the most preventable chronic conditions.
Regular screening, a balanced diet, exercise, and not smoking can dramatically reduce your risk.
By catching early warning signs, you can make informed choices and protect your heart for the long term. Schedule your heart screening today and take the first step toward a stronger, healthier future.
