Many people &#8211; even patients and sometimes clinicians &#8211; use them interchangeably, but they are not exactly the same. Understanding the distinction can help you recognize symptoms early, seek timely medical care, and explore modern tools like ECG monitoring to protect your heart health.<\/span><\/p>\n<h2><b>What Is Coronary Artery Disease (CAD)?<\/b><\/h2>\n<p><a href=\"https:\/\/blog.fourthfrontier.com\/what-is-coronary-artery-disease-and-how-can-you-detect-it-early\/\"><span style=\"font-weight: 400;\">Coronary Artery Disease<\/span><\/a><span style=\"font-weight: 400;\"> refers specifically to a condition where the coronary arteries, the vessels that supply oxygen-rich blood to the heart, become narrowed or blocked. This narrowing usually happens due to atherosclerosis &#8211; the buildup of fatty deposits, cholesterol, and calcium (known as plaque) inside the arteries.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When the arteries are narrowed, blood flow to the heart muscle is reduced, increasing the risk of chest pain (angina), shortness of breath, or even myocardial infarction (heart attack).<\/span><\/p>\n<p><b>Common CAD symptoms include:<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pressure or pain in the chest (angina)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Shortness of breath during exertion<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fatigue or weakness<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pain radiating to the neck, jaw, shoulders, or arms<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">CAD is often described as the most common type of heart disease and is sometimes referred to as arteriosclerotic cardiovascular disease or atherosclerotic heart disease in medical literature.<\/span><\/p>\n<h2><b>What Is Ischemic Heart Disease (IHD)?<\/b><\/h2>\n<p><a href=\"https:\/\/blog.fourthfrontier.com\/ischemic-heart-disease-symptoms-types-and-effective-treatments\/\"><span style=\"font-weight: 400;\">Ischemic Heart Disease<\/span><\/a><span style=\"font-weight: 400;\"> is a broader term that refers to any heart problem caused by reduced blood supply (ischemia) to the heart muscle.
