Coronary Artery Disease with Subsequent Heart Damage - Medical Illustration, Human Anatomy Drawing
This illustration demonstrates three stages of coronary artery anatomy and pathology. In the normal condition, the coronary arteries, including the left and right coronary arteries, branch from the aorta to supply oxygenated blood to the myocardium. Key branches such as the circumflex artery and left anterior descending artery (LAD) are labeled, showing a healthy vascular structure. The second panel depicts coronary artery occlusions, including complete blockages in the circumflex artery and its first marginal branch, the right coronary artery at the first inferior bend, and the distal LAD, as well as a 30-50% stenosis in the first diagonal branch off the LAD. The final panel illustrates myocardial infarction, where arterial blockages have resulted in ischemia and necrosis of the affected heart muscle tissue, highlighting areas of infarction caused by insufficient blood flow.
