It develops when the blood vessels that supply\u00a0<\/p>\n<p>blood to the heart muscle become narrow or blocked. When the heart does not receive enough blood and oxygen, it can cause\u00a0<\/p>\n<p>chest discomfort and other symptoms. The good news is that coronary artery disease can often be managed when it is detected\u00a0<\/p>\n<p>early. Knowing the warning signs and getting the right medical evaluation can help protect your heart health.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:heading --><\/p>\n<h2 class=\"wp-block-heading\">What Is Coronary Artery Disease?<\/h2>\n<p><!-- \/wp:heading --><!-- wp:paragraph --><\/p>\n<p>The heart needs a continuous supply of oxygen-rich blood to work properly. This blood reaches the heart through the coronary\u00a0<\/p>\n<p>arteries. Over time, fatty deposits called <strong>plaque<\/strong> can build up inside these arteries. This process is known as atherosclerosis. As<\/p>\n<p>\u00a0plaque increases, the artery can become narrower, making it harder for blood to reach the heart muscle.In some cases, a blood\u00a0<\/p>\n<p>clot can form around a damaged plaque and suddenly block blood flow. This can lead to a heart attack and requires immediate\u00a0<\/p>\n<p>medical attention.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:heading --><\/p>\n<h2 class=\"wp-block-heading\">What Causes Coronary Artery Disease?<\/h2>\n<p><!-- \/wp:heading --><!-- wp:paragraph --><\/p>\n<p>Coronary artery disease usually develops gradually over many years.
