    Welcome back to “Cardiology: An Introduction.” This is Part 5. We are going to discuss cardiovascular pharmacology in this component and also in the next. Not all cardiovascular drugs will be discussed, of course, because there’s a huge array of them. But we’re going to talk about the major drugs that are used every day for patients with a variety of heart diseases. First of all, it’s important to understand which diseases one would treat with various drugs. What are the diseases that we are going to be talking about later in much more detail? The commonest heart diseases are high blood pressure or hypertension, coronary artery disease, heart failure and cardiac arrhythmias - in other words, electrical short circuits or abnormalities in the heart. The drugs that we are going to be discussing can be used for each of these indications and we are going to go through three drug or three classes of drugs in this lecture. Now, it’s important to understand that with drugs, there is not one effect from the drug. In fact, drugs have many effects. Unfortunately, some of those effects are very unpleasant and they vary from person to person. So, let’s take a theoretical example - you have Drug A. You give it to a patient to lower the blood pressure. Wonderful! The blood pressure comes down. But, unfortunately, the drug upsets the patient’s stomach, so that every time the patient thinks about eating, they get nauseous. Well clearly, that’s not a good drug for that patient. Now, it turns out that there are many drugs for high blood pressure. So fortunately, we usually can try others in order to find one that will both take the patient’s blood pressure down and not cause indigestion or another side effect. But, since the drugs...
