Heart Disease
What is Heart Disease?
Heart disease refers to several conditions that affect your heart's structure and function. The most common type is coronary artery disease, which happens when blood vessels that supply your heart become narrow or blocked. This reduces blood flow and oxygen to your heart muscle.
When plaque builds up in your arteries, it causes inflammation and restricts circulation. Over time, this can lead to chest pain, heart attack, or heart failure. Heart disease develops slowly over many years, often without obvious warning signs.
The good news is that many forms of heart disease can be prevented or managed through lifestyle changes and early detection. Understanding your risk factors and monitoring key biomarkers can help you take steps to protect your heart health before serious problems develop.
Symptoms
- Chest pain or discomfort, often described as pressure or squeezing
- Shortness of breath during activity or at rest
- Pain or numbness in your arms, shoulders, neck, jaw, or back
- Fatigue or unusual tiredness that limits daily activities
- Rapid or irregular heartbeat
- Swelling in your legs, ankles, or feet
- Dizziness or lightheadedness
- Nausea or loss of appetite
Many people with early heart disease have no symptoms at all. This is why regular blood testing to check inflammation and cholesterol levels is so important for prevention.

Causes and risk factors
Heart disease develops when plaque made of cholesterol, fat, and other substances builds up inside your arteries. This process is called atherosclerosis. Inflammation in your blood vessels speeds up plaque formation and increases risk. High cholesterol, especially high LDL and low HDL, contributes to blockages. High blood pressure damages artery walls over time. Smoking harms blood vessels and reduces oxygen in your blood. Diabetes raises your risk because high blood sugar damages arteries.
Other risk factors include being overweight, eating a diet high in processed foods and saturated fats, lack of physical activity, chronic stress, and excessive alcohol consumption. Family history plays a role too. Age increases risk, especially after 45 for men and 55 for women. Some nutrients like folate affect homocysteine levels, an amino acid linked to heart disease risk when elevated. Elevated GGT levels may also indicate increased risk, though researchers are still studying this connection.
How it's diagnosed
Doctors diagnose heart disease through a combination of medical history, physical exam, and diagnostic tests. Blood tests are often the first step to check for risk factors. Key markers include cholesterol levels like HDL, LDL, and total cholesterol, along with the cholesterol to HDL ratio. C-reactive protein measures inflammation in your blood vessels. Folate levels matter because low folate can increase homocysteine, which raises heart disease risk. GGT levels may also indicate increased risk.
Rite Aid offers blood testing that checks these important markers twice a year. Testing helps you catch warning signs early, before symptoms appear. Your doctor may also order an EKG to check your heart rhythm, a stress test to see how your heart performs during activity, or imaging tests like an echocardiogram or CT scan to look at your heart structure and blood flow.
Treatment options
- Eat a heart healthy diet rich in vegetables, fruits, whole grains, lean proteins, and healthy fats like olive oil and fish
- Reduce processed foods, added sugars, and saturated fats
- Exercise at least 150 minutes per week with a mix of cardio and strength training
- Quit smoking and limit alcohol to no more than 1 drink per day for women or 2 for men
- Maintain a healthy weight and reduce stress through practices like meditation or yoga
- Get 7 to 9 hours of quality sleep each night
- Statins to lower cholesterol levels when lifestyle changes are not enough
- Blood pressure medications like ACE inhibitors or beta blockers
- Aspirin therapy to prevent blood clots in some cases
- Diabetes medications to control blood sugar if needed
- Procedures like angioplasty or bypass surgery for severe blockages

Frequently asked questions
Early heart disease often has no symptoms, which is why regular blood testing is so important. When symptoms do appear, they may include chest discomfort, shortness of breath, unusual fatigue, or pain in your arms or jaw. Some people notice their symptoms only during physical activity at first.
While you cannot completely reverse damage to your arteries, you can slow or stop progression through major lifestyle changes. Studies show that a plant based diet, regular exercise, stress management, and quitting smoking can reduce plaque buildup. Some people have even seen plaque reduction with intensive lifestyle programs. Early detection and consistent action give you the best chance to protect your heart.
Key blood tests include cholesterol panels that measure HDL, LDL, and total cholesterol levels. C-reactive protein checks for inflammation in your blood vessels. Folate levels matter because low folate increases homocysteine, which raises heart disease risk. GGT levels may also indicate increased risk, though research is ongoing.
Most adults should check cholesterol and inflammation markers every 4 to 6 years starting at age 20. If you have risk factors like high cholesterol, diabetes, or family history, testing twice a year helps you track changes and adjust your prevention plan. Rite Aid offers testing twice yearly to help you stay on top of your heart health.
For most people, total cholesterol should be below 200 mg/dL, LDL below 100 mg/dL, and HDL above 40 mg/dL for men or 50 mg/dL for women. Your target numbers may differ based on your individual risk factors. The ratio of total cholesterol to HDL is also important, with lower ratios indicating better heart health.
Family history increases your risk, but it does not guarantee you will develop heart disease. Genetics load the gun, but lifestyle pulls the trigger. Even with a strong family history, you can lower your risk significantly through healthy eating, regular exercise, maintaining a healthy weight, and not smoking. Know your family history and share it with your doctor.
Focus on vegetables, fruits, whole grains, beans, nuts, seeds, and fatty fish like salmon. Olive oil, avocados, and other sources of healthy fats support heart health. Limit red meat, processed meats, fried foods, and foods high in added sugar or salt. The Mediterranean diet pattern has strong evidence for heart disease prevention.
Chronic stress contributes to heart disease through multiple pathways. It raises blood pressure, increases inflammation, and often leads to unhealthy coping behaviors like overeating or smoking. Stress hormones like cortisol can damage blood vessels over time. Managing stress through exercise, meditation, social connection, and adequate sleep helps protect your heart.
Heart disease develops over decades, so the choices you make in your 20s and 30s matter. Plaque buildup starts early in life, especially with poor diet and inactivity. Young adults with risk factors like obesity, diabetes, or smoking can develop serious heart problems before age 40. Prevention should start at any age.
LDL cholesterol is often called bad cholesterol because it deposits in artery walls and forms plaque. HDL cholesterol is called good cholesterol because it carries cholesterol away from arteries back to your liver for removal. Higher HDL and lower LDL reduce your heart disease risk. The size of LDL particles also matters, with smaller particles being more harmful.
