What is Coronary Artery Disease? Featured

Coronary Artery Disease, also called Coronary Heart Disease, affects millions of Americans. This serious disease is a result of plaque buildup in your arteries.

The arteries, which start out smooth and elastic, get plaque on their inner walls, which can make them more rigid and narrowed. This restricts blood flow to your heart, which also restricts the flow of oxygen to your heart.

If the flow of oxygen-rich blood to your heart muscle is reduced or blocked, angina or a heart attack can occur. A heart attack occurs if the flow of oxygen-rich blood to a section of heart muscle is cut off. If blood flow isn’t restored quickly, the section of heart muscle begins to die. Without quick treatment, a heart attack can lead to serious health problems or death.

Over time, Congenital Heart Disease can weaken the heart muscle and lead to heart failure and arrhythmias

Symptoms of Coronary Heart Disease

  • Chest pain (angina). You may feel pressure or tightness in your chest, as if someone were standing on your chest. This pain, referred to as angina, usually occurs on the middle or left side of the chest. Angina is generally triggered by physical or emotional stress. 
  • Shortness of breath. If your heart can't pump enough blood to meet your body's needs, you may develop shortness of breath or extreme fatigue with exertion.
  • Heart attack. A completely blocked coronary artery may cause a heart attack. The classic signs and symptoms of a heart attack include crushing pressure in your chest and pain in your shoulder or arm, sometimes with shortness of breath and sweating.

Women are somewhat more likely than men are to experience less typical signs and symptoms of a heart attack, such as neck or jaw pain. Sometimes a heart attack occurs without any apparent signs or symptoms.

Causes of Coronary Heart Disease

Coronary artery disease is thought to begin with damage or injury to the inner layer of a coronary artery, sometimes as early as childhood. The damage may be caused by a variety of factors, including:

Risk factors

Risk factors for coronary artery disease include:

  • Age - Simply getting older increases your risk of damaged and narrowed arteries.
  • Sex - Men are generally at greater risk of coronary artery disease. However, the risk for women increases after menopause.
  • Family history - A family history of heart disease is associated with a higher risk of coronary artery disease, especially if a close relative developed heart disease at an early age.
  • Smoking - People who smoke have a significantly increased risk of heart disease.
  • High blood pressure - Uncontrolled high blood pressure can result in hardening and thickening of your arteries, narrowing the channel through which blood can flow.
  • High blood cholesterol levels - High levels of cholesterol in your blood can increase the risk of formation of plaques and atherosclerosis.
  • Diabetes - Diabetes is associated with an increased risk of coronary artery disease. Type 2 diabetes and coronary artery disease share similar risk factors, such as obesity and high blood pressure.
  • Overweight or obesity - Excess weight typically worsens other risk factors.
  • Physical inactivity - Lack of exercise also is associated with coronary artery disease
  • High stress. Unrelieved stress in your life may damage your arteries as well as worsen other risk factors for coronary artery disease.
