Coronary heart disease (CHD) can develop gradually without causing symptoms that are easy to recognize. As the coronary arteries become increasingly narrowed, the supply of blood and oxygen to the heart muscle can decrease, potentially causing chest pain, shortness of breath, and even a heart attack.
The heart works continuously to pump blood throughout the body. To perform this function, the heart muscle also needs its own supply of blood and oxygen, which is delivered through the coronary arteries.
Coronary arteries are blood vessels located on the surface of the heart that carry oxygen-rich blood to the heart muscle. Problems can occur when these arteries become narrowed or blocked.
One condition associated with this process is atherosclerosis, in which plaque builds up along the walls of the arteries. Plaque can contain cholesterol, fat, calcium, and other substances that gradually accumulate over time.
As plaque increases and the artery becomes more narrowed, blood flow to the heart muscle can become restricted.
How Does Coronary Heart Disease Develop?
Coronary heart disease usually does not develop suddenly. The process can take place over many years, and a person may not notice changes in the coronary arteries during the early stages.
Atherosclerosis is one of the key processes involved in the development of CHD. As plaque builds up along the artery wall, the space inside the artery becomes narrower, limiting blood flow.
Several factors can increase the risk of plaque buildup and coronary heart disease.
High Cholesterol
High levels of low-density lipoprotein (LDL) cholesterol can contribute to the buildup of fatty deposits in artery walls. Over time, this can cause the arteries to become increasingly narrowed.
High Blood Pressure
Uncontrolled hypertension can place continuous stress on artery walls. This may increase the risk of blood vessel damage and contribute to plaque formation.
Smoking
Chemicals in cigarette smoke can damage blood vessels and increase the risk of heart disease. Smoking can also worsen the process of narrowing the arteries.
Diabetes
Persistently high blood sugar levels can affect blood vessel health and increase the risk of coronary heart disease.
Physical Inactivity and an Unhealthy Lifestyle
Lack of physical activity, an unbalanced diet, and excess body weight can increase several risk factors for CHD, including high blood pressure, high cholesterol, and diabetes.
Age and Family History
The risk of coronary heart disease can also be influenced by age, family history, and certain underlying health conditions.
When Plaque Ruptures, Heart Attack Risk Can Increase
Narrowed arteries are not the only concern in coronary heart disease. The surface of a plaque can become damaged or rupture, causing the body to form a blood clot at the site.
If the clot becomes large enough, it can restrict or completely block blood flow to the heart muscle. When blood flow is interrupted, a heart attack can occur.
For this reason, sudden symptoms—particularly chest pain or pressure accompanied by other symptoms—require immediate attention.
Recognizing the Symptoms of Coronary Heart Disease
Symptoms of CHD are not the same for everyone. Some people experience more typical symptoms, while others may have mild symptoms or may not realize that a heart problem is developing.
Possible symptoms include:
Chest Pain or Discomfort
Chest symptoms may feel like pressure, heaviness, squeezing, fullness, or burning.
Discomfort may occur during physical activity or emotional stress and may improve with rest. It can also spread to the arms, shoulders, neck, jaw, back, or upper abdomen.
Shortness of Breath
Reduced blood flow to the heart muscle can affect the heart's ability to function properly. Shortness of breath may occur, particularly during physical activity.
New or worsening shortness of breath, especially when accompanied by chest pain, should be medically evaluated.
Unusual Fatigue
Unusual tiredness, particularly when performing activities that were previously easy, can occur with heart problems.
However, fatigue is a common symptom that can have many other causes. Medical evaluation may be needed to determine the underlying cause.
Dizziness or Feeling Faint
Problems with blood flow or certain conditions affecting heart rhythm can cause dizziness, weakness, or a sensation of being about to lose consciousness.
These symptoms should be evaluated, particularly if they occur repeatedly or are accompanied by chest pain, shortness of breath, or a racing or irregular heartbeat.
Pain That Spreads to Other Areas
Heart-related discomfort is not always limited to the chest. Pain or discomfort can spread to one or both arms, the shoulders, back, neck, jaw, or upper abdomen.
For this reason, discomfort in these areas should not automatically be assumed to be caused by muscle problems or indigestion, especially when it occurs together with other symptoms that may indicate a heart problem.
Cold Sweats and Nausea
Some people may experience cold sweats, nausea, vomiting, upper abdominal discomfort, or severe weakness.
Heart attack symptoms can vary from person to person. In some groups, including women and people with diabetes, symptoms may be less typical.
When Should You Go to the Emergency Department?
Chest pain or pressure lasting several minutes, particularly when accompanied by shortness of breath, cold sweats, nausea, dizziness, or pain spreading to the arms, jaw, back, or shoulders, can be a sign of a medical emergency.
Do not wait for the symptoms to become more severe. Seek emergency medical care immediately if symptoms suggest a possible heart attack.
Prompt treatment is important because the longer blood flow to the heart muscle is disrupted, the greater the potential for damage to the heart muscle.
How to Reduce the Risk of Coronary Heart Disease
Not all CHD risk factors can be changed. However, many can be addressed through healthier habits and regular health checkups.
Follow a Balanced Diet
Eat more vegetables, fruits, whole grains, and healthy sources of protein.
Limit excessive consumption of foods high in saturated fat, trans fat, added sugar, and salt, as well as highly processed foods.
Stay Physically Active
Engage in regular physical activity according to your ability and health condition.
In general, adults are advised to get about 150 minutes of moderate-intensity physical activity per week or about 75 minutes of vigorous-intensity activity per week.
Walking, cycling, and actively doing household tasks can all be part of a healthier lifestyle.
Quit Smoking
Quitting smoking is an important step toward reducing heart disease risk. Exposure to secondhand smoke should also be avoided whenever possible.
Maintain a Healthy Weight
Aim to maintain a healthy weight through a combination of a balanced diet and regular physical activity.
Manage Stress
Long-term stress can affect several aspects of health.
Make time for rest, enjoyable activities, exercise, or relaxation techniques that work for you.
Monitor Blood Pressure
Hypertension often causes no noticeable symptoms. Regular blood pressure checks are important so that high blood pressure can be identified and managed earlier.
Check Your Cholesterol
Cholesterol testing can help assess the levels of fats in your blood.
If your cholesterol is high, discuss lifestyle changes or treatment options with your doctor.
Manage Blood Sugar
For people with diabetes, keeping blood sugar under control is an important part of reducing the risk of complications involving the blood vessels and heart.
Protecting Your Heart Starts With Everyday Habits
Coronary heart disease can develop gradually and may not cause obvious symptoms in its early stages. For this reason, protecting heart health should begin before symptoms appear.
Understanding risk factors, following healthy lifestyle habits, having regular health checks, and paying attention to unusual symptoms are all important parts of maintaining heart health.
If you experience chest pain or pressure lasting several minutes, especially when accompanied by shortness of breath, cold sweats, nausea, dizziness, or pain spreading to the arms, jaw, back, or shoulders, seek emergency medical care immediately.
Taking care of your heart is not only about preventing disease. It also means recognizing changes in your body and taking action when symptoms require medical attention.
