How to use this book This book is adapted from the first chapter of Northwestern Medical Review’s Primary Care for the USMLE and COMLEX book. It contains exceptionally high-yield material found on board exams. The mini-chapters are divided into sections containing commonly tested concepts with keywords that should immediately come to mind while you’re taking your exam. In the back of the book are two additional sections: a Test Your Knowledge section containing questions and answers with explanations from our follow-along lecture workbooks and NMR Question Bank, and a Sample Mnemonics section containing examples of memorable mnemonics from our course material. A note from the author This book is yours. It is your companion for the boards. Until your exam is over, you would be smart to have it handy – in your backpack, in your jacket, or in your pocket. You can read it anywhere – on a bus, on a train, on a plane, or even in the rain. This book has no beginning and no end. Each part is both dependent on and independent of the other parts. Much like the human body. You can start it anywhere – at the beginning, in the middle, or at the end. You can open it anytime – early morning, midday, or at night. You may write on it, draw on it, and add to it – and you may do so as your heart desires. It will tell you how much you have learned and what you have yet to learn. The more you read it, wear it, and tear it, the more you will earn from it. And when it’s all over, you will remember that you had one companion the whole way – the one that was there for you every day. Dr. Jahan Eftekar Table of Contents 1. Cardiology 1 2. Vasculitides 6 3.
