James Edwards does a two-part chat with Dr. Sean Lal. Sean’s clinical and research interests are in heart failure.
In this second part of the podcast, we look at:
In Part 1 we go through what heart failure is and it’s common causes.

Heart failure (HF) is a clinical condition. It’s a result of an impaired ability of the heart to provide output to perfuse organs sufficiently. This is due to abnormalities of heart structure and function. There are two main mechanisms by which heart failure can occur.
Systolic heart failure results in impaired contractile function. Thereby, it reduces the output to the body.
Diastolic dysfunction results from abnormal cardiac relaxation. And this happens where a stiff ventricle is not able to fill adequately. These two pathological processes often coexist together.

Introduction
Heart failure (HF) is a clinical condition resulting from an impaired ability of the heart to provide output to perfuse organs sufficiently due to abnormalities of heart structure and function. There are two main mechanisms by which heart failure can occur. Systolic heart failure results in impaired contractile function thereby reducing output to the body. Diastolic dysfunction, on the other hand, results from abnormal cardiac relaxation where a stiff ventricle is not able to fill adequately. These two pathological processes often coexist together. In this second part of the podcast, we will look at how best to investigate heart failure, what are the common precipitants, what type of drugs are used and when to escalate care.
