    Welcome back to the third lecture in the basic vascular medicine series. In this one, we’re going to talk about making the diagnosis of problems in the vascular system. And we’ll start with basic diagnostic techniques. So the learning objectives. The first one: what kind of diagnostic techniques are there? What is the range of diagnostic techniques? Here you can see a little diagram showing you the various types of diagnostic techniques. There are basic diagnostic techniques such as the history – that is what the patient tells you – and the physical exam. And then, there are more sophisticated diagnostic techniques that are usually instrument-based and consist of a number of tests: blood tests or other forms of tests. And we’ll be talking about each of those later in this lecture. Why is the patient’s history so very important? Let’s consider that for a few moments. First of all, it’s important to remember that cardiovascular disease is the leading cause of death in the world regardless of racial or ethnic groups. For example, in 2012 there were 7.4 million ischemic heart disease deaths – that is disease due to narrowing of the blood vessels in the heart – and 6.7 million deaths that resulted from stroke. So you can see that that’s a huge number of people in the world who have died of cardiovascular disease. In making the diagnosis of either one of those entities – ischemic heart disease or stroke – it is critically important to know what symptoms the patient’s been having because that directs you in terms of your thinking as to what’s going on in this particular patient. The history provides information about the symptoms, how they might have developed. It indicates potential or underlying disease states. It helps in identifying significant factors that...
