Ninja Nerds!
In this lecture Professor Zach Murphy will be presenting on Antianginal Drugs. During this lecture we will be starting with a review of the basic pathophysiology of Angina. After we discuss the fundamentals of angina we will move into the various drug categories used to treat angina including: Beta Blockers, Calcium Channel Blockers, Nitrates, and Ranolazine. At the conclusion of this lecture we will be going over 10 practice problems to truly master this topic! We hope you enjoy this lecture and be sure to support us below!

Antianginal drugs are a group of medications that are used to treat angina, a condition in which the heart muscle does not receive enough blood and oxygen. This condition can cause chest pain, discomfort, shortness of breath, and other symptoms. Antianginal drugs work by dilating the blood vessels and improving blood flow to the heart muscle, which helps to relieve the symptoms of angina.
There are several types of antianginal drugs, including nitrates, beta-blockers, and calcium channel blockers. Nitrates, such as nitroglycerin, work by relaxing the smooth muscles in the blood vessels, which helps to increase blood flow to the heart. Beta-blockers, such as metoprolol, work by blocking the effects of adrenaline on the heart, which helps to slow the heart rate and reduce the workload on the heart. Calcium channel blockers, such as verapamil, work by blocking the entry of calcium ions into the heart muscle cells, which helps to relax the blood vessels and improve blood flow.
While antianginal drugs can be very effective in relieving the symptoms of angina, they are not a cure for the underlying condition. In addition, these medications can have side effects, such as headache, dizziness, and low blood pressure. It is important to work closely with a healthcare provider to determine the best treatment plan for managing angina and to monitor any potential side effects of antianginal drugs.
