Post-mortem specimen of human heart
Post-mortem specimen of a human heart featuring an occluded (blocked) coronary artery; the blockage appears as the redder area at top centre. Branches of both left & right coronary arteries, which supply the heart muscle with oxygen, are seen below the surface. Total occlusion of a coronary artery typically occurs as a result of clot (thrombus) formation, often when the diameter of the interior (lumen) has been reduced by the formation of fatty atheroma plaque. As a result of the occlusion, blood supply to heart muscle below the blockage is reduced (ischaemia) or ceased, leading to the death of tissue supplied - an acute myocardial infarction or heart attack

EDITORS COMMENTS
This striking print from Science Photo Library captures a post-mortem specimen of a human heart, revealing the devastating effects of an occluded coronary artery. The top center area appears redder, indicating the blockage that has occurred. Below the surface, we can observe the branches of both left and right coronary arteries, responsible for supplying oxygen to the heart muscle. The total occlusion of a coronary artery is typically caused by clot formation, often due to fatty plaque build-up within the artery's interior. This narrowing reduces blood flow and leads to ischemia or even complete cessation of blood supply below the blockage. Consequently, this lack of oxygen-rich blood results in tissue death - an acute myocardial infarction or heart attack. This image serves as a powerful reminder of how crucial it is to maintain cardiovascular health and prevent conditions like coronary artery disease. It highlights the intricate network within our bodies that ensures proper functioning but can also be vulnerable if not cared for properly. Science Photo Library provides us with invaluable visual resources like this one that aid medical professionals in understanding diseases and disorders related to cardiac health. Through such images, we gain insight into these complex conditions while appreciating the delicate balance required for optimal well-being.
