Welcome to the 1st lesson in our new series on Heart Failure. In this lesson we start off with the basics and talk simply about what is heart failure. The goal of this lesson isn't to go too in-depth just yet, but to give you a good overview of what exactly is going on with your patient when they have heart failure.

We start the lesson off with a quick overview of the role of the heart and then dive in to some astonishing facts about the prevalence of heart failure in not only our patients, but the entire population.

From there we take a 10,000ft view at the heart failure pathophysiology. We give a quick intro to the 2 dysfunctions, systolic and diastolic heart failure, as well as explain how these can manifest on the left side, right side, or as bi-ventricular failure.

Next we talk about the cause of heart failure. We save more specific causes for future lessons, but for this one, we mainly talk about how some other underlying disease process leads to the death of muscle cells and thus decreased cardiac output, and as a result, starts the cyclical progression of heart failure.

Finally, we cover the 3 types of compensation that you will see in your patients and what is happening with these mechanisms to try and make up for the lost cardiac output. We further show though how unfortunately these mechanisms which were designed to help our patients out actually end up having a negative impact and feed in to the cycle of progression. This leads in to the last thing we discuss which is decompensation and how these compensation mechanisms are really the basis for our patient progressing in to this state of decompensation.

Our hope by the end of this lesson is that you have a pretty good overview of heart failure in your patients and that you will be able to take this information and carry it forward in to the remaining lessons to further advance your understanding!
