It also has its own blood supply via the coronary arteries.<\/p>\n<p>The term <em>myocardial<\/em> means \u201cmuscle of the heart\u201d. An infarction is an interruption of the blood supply to a tissue, usually caused by a blood clot, or thrombus. Therefore, a myocardial infarction is the interruption of the blood supply to the heart. This typically occurs due to <a class=\"ylist\" href=\"https:\/\/www.mometrix.com\/academy\/coronary-artery-disease\/\">blockage of coronary arteries<\/a>.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2025\/03\/heart-blockage.webp\" alt=\"\" width=\"\" height=\"\" class=\"aligncenter size-full wp-image-215971\"  role=\"img\" \/><\/p>\n<p>Loss of blood to an area of the heart equals loss of oxygen. When our tissues in the body are deprived of oxygen for a period of time they can become damaged and even die. Myocardial infarction is commonly referred to as a heart attack.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2025\/03\/loss-of-blood-and-oxygen.webp\" alt=\"\" width=\"\" height=\"\" class=\"aligncenter size-full wp-image-215971\"  role=\"img\" \/><\/p>\n<p>A heart attack occurs in three stages: ischemia, injury, and infarction.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2025\/03\/heart-stages-or-something-idk.webp\" alt=\"\" width=\"\" height=\"\" class=\"aligncenter size-full wp-image-215971\"  role=\"img\" \/><\/p>\n<p><strong>Ischemia<\/strong> is a restriction of blood flow (and thus a shortage of oxygen) to tissues in the body. Again, this occurs typically due to an occlusion or blood clot. Prolonged lack of oxygen to the heart muscle causes <strong>injury<\/strong> to the cells of the myocardium. If the circulation is not restored, cell death or <strong>infarction<\/strong> occurs, meaning a portion of the heart muscle dies or sustains permanent damage.<\/p>\n<p>Three types of heart attack are: ST-segment elevation myocardial infarction (STEMI), Non-ST-segment elevation myocardial infarction (non-STEMI), and Coronary spasm (also known as unstable angina).<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2025\/03\/3-types-of-heart-attacks.webp\" alt=\"\" width=\"\" height=\"\" class=\"aligncenter size-full wp-image-215971\"  role=\"img\" \/><\/p>\n<p>STEMI is named for the ST elevation seen on an electrocardiogram. The PQRST waves show the electrical conduction through the heart muscle, and when ST is elevated this is demonstrating a partial or complete blockage of a major coronary artery and is life-threatening. <\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2025\/03\/pqrst.webp\" alt=\"\" width=\"\" height=\"\" class=\"aligncenter size-full wp-image-215971\"  role=\"img\" \/><\/p>\n<p>Depending on the number and type of blockages, the patient may need to have an emergent cardiac catheterization to remove the blockage, or open-heart surgery.<\/p>\n<\/div>\n<\/div>\n\n<div class=\"home-buttons\">\n<p><a href=\"https:\/\/www.mometrix.com\/academy\/biology\/\">Return to Biology Videos<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Return to Biology Videos<\/p>\n","protected":false},"author":1,"featured_media":186485,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":{"0":"post-63811","1":"page","2":"type-page","3":"status-publish","4":"has-post-thumbnail","6":"page_category-anatomy-and-physiology-videos","7":"page_category-biology-videos","8":"page_category-cardiovascular-videos","9":"page_category-physiological-integrity","10":"page_category-video-pages-for-study-course-sidebar-ad","11":"page_type-video","12":"subject_matter-nursing"},"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 4.9.8 - aioseo.com -->\n\t<meta name=\"description\" content=\"The heart is a crucial organ for life because it circulates blood throughout the body.
