Coronary Artery Disease Blood Test

What is Coronary Artery Disease?

Coronary artery disease is a condition where the major blood vessels supplying the heart become narrowed or blocked. It is caused by atherosclerotic plaque buildup consisting of cholesterol, fatty deposits, and inflammatory cells in the coronary arteries. The Lipid Panel is the most important test for assessing coronary artery disease risk because it measures LDL cholesterol levels that directly contribute to plaque formation.

What causes coronary artery disease?

Coronary artery disease is caused by atherosclerosis, a process where plaque composed of cholesterol, fat, calcium, and other substances accumulates in the coronary arteries. This buildup is primarily driven by elevated LDL cholesterol levels, chronic inflammation, high blood pressure, diabetes, and smoking. Over time, these plaques narrow the arteries, restricting oxygen-rich blood flow to the heart muscle and increasing the risk of heart attack and other cardiac events.

What is the best test for coronary artery disease?

The Lipid Panel is the most important blood test for coronary artery disease because it measures total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides that directly contribute to plaque formation. For more comprehensive risk assessment, the Cardio IQ Advanced Lipid Panel provides detailed analysis of lipid particle sizes and subtypes, while the Lipoprotein Fractionation NMR test measures the actual number of LDL particles (LDL-P), which is a stronger predictor of cardiovascular risk than standard LDL cholesterol alone. The Myeloperoxidase test can identify unstable plaques that are more likely to rupture and cause heart attacks.

When should I get tested for coronary artery disease?

You should get tested if you have a family history of heart disease, are over 40 years old, have high blood pressure or diabetes, smoke, or are overweight. Testing is also important if you experience symptoms like chest pain or discomfort, shortness of breath with activity, unusual fatigue, or pain radiating to your jaw, neck, or arm. Adults should have their cholesterol checked at least every 4-6 years starting at age 20, with more frequent testing if risk factors are present.

What are the symptoms of coronary artery disease?
The most common symptom of coronary artery disease is angina, which feels like chest pressure, tightness, or squeezing that often occurs during physical activity or emotional stress. You might also experience shortness of breath, extreme fatigue, pain in the shoulders, arms, neck, jaw, or back, and heart palpitations. Some people, especially women and those with diabetes, have atypical symptoms like nausea, indigestion, or weakness. Many people with early coronary artery disease have no symptoms at all, which is why screening blood tests are so important.
Who is at risk for coronary artery disease?
People at highest risk include those with high LDL cholesterol, low HDL cholesterol, high blood pressure, diabetes, or a family history of early heart disease. Smoking significantly increases risk, as does being overweight or obese, living a sedentary lifestyle, and experiencing chronic stress. Men over 45 and women over 55 (or after menopause) face increased risk. Certain ethnic groups, including African Americans, Mexican Americans, and Native Americans, also have higher rates of coronary artery disease.
What happens if coronary artery disease is left untreated?
Untreated coronary artery disease progressively worsens as plaques continue to build up and narrow the arteries. This can lead to heart attack when a plaque ruptures and forms a blood clot that completely blocks blood flow to part of the heart muscle. Chronic reduced blood flow can weaken the heart muscle, leading to heart failure where the heart cannot pump blood effectively. You may also develop dangerous heart rhythm problems (arrhythmias), and the overall risk of sudden cardiac death increases significantly without treatment.
Can coronary artery disease be diagnosed with a blood test?
Blood tests cannot definitively diagnose coronary artery disease, but they are essential for assessing your risk and detecting the underlying conditions that cause it. Lipid panels measure the cholesterol levels that contribute to plaque buildup, while advanced tests like Myeloperoxidase can identify inflammatory markers associated with unstable plaques. BNP levels can indicate if your heart is under stress from reduced blood flow. Definitive diagnosis typically requires imaging tests like coronary angiography, but blood tests guide treatment decisions and help monitor disease progression.
How is coronary artery disease treated?
Treatment focuses on lifestyle changes, medications, and sometimes procedures to restore blood flow. Lifestyle modifications include adopting a heart-healthy diet low in saturated fats, exercising regularly, quitting smoking, and managing stress. Medications like statins lower cholesterol, while blood pressure medications, aspirin, and other antiplatelet drugs reduce complications. For more advanced disease, procedures like angioplasty with stent placement or coronary artery bypass surgery may be necessary to restore adequate blood flow to the heart muscle.
How can I prevent coronary artery disease?
Prevention centers on controlling risk factors through healthy lifestyle choices. Maintain healthy cholesterol levels through a diet rich in fruits, vegetables, whole grains, and lean proteins while limiting saturated fats and trans fats. Exercise for at least 150 minutes per week, maintain a healthy weight, and avoid tobacco products. Manage conditions like high blood pressure and diabetes through regular monitoring and medication if needed. Regular blood tests to check cholesterol and other cardiac markers help you catch problems early when they are easiest to address.
What natural remedies help with coronary artery disease?
While natural approaches should complement rather than replace medical treatment, certain strategies support heart health. Omega-3 fatty acids from fish or supplements can reduce inflammation and triglycerides. Plant sterols and soluble fiber from oats, beans, and fruits help lower cholesterol naturally. Regular consumption of nuts, especially almonds and walnuts, improves lipid profiles. Green tea contains antioxidants that protect blood vessels, and garlic may have mild cholesterol-lowering effects. Stress reduction through meditation, yoga, or deep breathing exercises can lower blood pressure and reduce cardiac stress.

What this means

Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
