Angina treatment: calcium antagonist mechanism
Angina treatment by calcium channel blockers. Artwork showing a calcium antagonist drug blocking membrane calcium channels in smooth muscle. This drug treats angina, hypertension and certain kinds of cardiac arrhythmia. Calcium channel blockers (green) interfere with the entry of calcium ions (orange) into smooth muscle cells via calcium channels (mauve). This impairs contraction of muscle fibres (bottom) inside the cells and causes relaxation of muscle in blood vessel walls. This improves the circulation of blood through the heart and reduces the blood pressure. The passage of nerve impulses through the heart are slowed, which helps correct certain arrhythmias

EDITORS COMMENTS
This artwork from Science Photo Library beautifully illustrates the mechanism behind angina treatment using calcium channel blockers. The print showcases a calcium antagonist drug effectively blocking membrane calcium channels in smooth muscle, offering relief to patients suffering from angina, hypertension, and certain types of cardiac arrhythmia. The image highlights how these green-colored calcium channel blockers interfere with the entry of orange-colored calcium ions into smooth muscle cells through mauve-colored calcium channels. By doing so, they impair the contraction of muscle fibers located at the bottom inside the cells and induce relaxation in blood vessel walls. This crucially improves blood circulation throughout the heart and reduces blood pressure. Furthermore, this intricate process also slows down nerve impulses passing through the heart, aiding in correcting specific arrhythmias that patients may experience. Science Photo Library's visually striking representation not only educates viewers about this vital medical treatment but also serves as a testament to their commitment to providing high-quality scientific imagery for healthcare professionals and researchers alike.
