It occurs when the coronary arteries that supply blood to the heart muscle become narrowed or blocked due to the buildup of plaque (fat, cholesterol, and other substances). This process, called atherosclerosis, can progress silently for years before showing symptoms.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The good news? If CAD is detected early, it can be treated and managed effectively, reducing the risk of heart attacks, heart failure, and other serious complications.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This article explains what CAD is, its warning signs, treatment options, and how patchless, chest-strap-based, long-term\u00a0 ECG monitors can support early detection and ongoing monitoring for people at risk.<\/span><\/p>\n<h3><b>Understanding Coronary Artery Disease<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Your coronary arteries are like pipelines that deliver oxygen-rich blood to your heart muscle. Over time, lifestyle factors, genetics, and certain health conditions can cause plaque to accumulate along their walls. As plaque builds up, arteries narrow, reducing blood flow to the heart.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If the blood supply becomes too restricted,<\/span><a href=\"https:\/\/my.clevelandclinic.org\/health\/diseases\/16898-coronary-artery-disease\"><span style=\"font-weight: 400;\"> it can lead to:<\/span><\/a><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Angina (chest pain or discomfort during exertion)<\/span>&nbsp;<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Shortness of breath<\/span>&nbsp;<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Heart attack (if the artery becomes completely blocked)<\/span>&nbsp;<\/li>\n<\/ul>\n<h3><a href=\"https:\/\/www.mayoclinic.org\/diseases-conditions\/coronary-artery-disease\/symptoms-causes\/syc-20350613\"><b>Key Symptoms of Coronary Artery Disease<\/b><\/a><\/h3>\n<p><span style=\"font-weight: 400;\">CAD can be a silent threat, with no symptoms in its early stages.
