Congestive Heart Failure Overview Part 1: Systolic vs Diastolic - Do you or a loved one suffer from shortness of breath, or do you get swelling in your legs, your feet, your ankles, and how about when you sleep?
Do you find that you have to prop yourself up on a bunch of pillows at night in order to breathe well while you sleep, or do you sometimes have to literally sleep sitting up in a chair in order to breathe well? If so, you might have congestive heart failure.
In this congestive heart failure overview we'll discuss the definition, the types of congestive heart failure, we'll talk about the causes as well as the warning signs and symptoms, the diagnosis, and the treatment. Click Here To See Part 1 of This 2 Part Series.

What Is Congestive Heart Failure?
Congestive heart failure (CHF) is a condition when the heart does not pump well enough in order to move blood throughout the body the way that it should.

How The Heart Works
The heart works in two phases. It works in phase one by contracting and squeezing blood and moving it forward, this is the systolic phase, and then phase two is the relaxation phase, when the heart relaxes and fills with blood. This is the diastolic phase.
Systolic vs Diastolic Heart Failure
Systolic Heart Failure
There are two types of heart failure, systolic heart failure, and diastolic heart failure. So let's first talk about systolic heart failure. Systolic heart failure, also called congestive heart failure with reduced ejection fraction, occurs when there is a failure of the heart to move enough blood forward during the contraction or the squeezing phase of the heart.
So what is the ejection fraction, or reduced ejection fraction? Ejection fraction is the amount or the proportion of blood that is squeezed out with each contraction. What does that mean? Let me give you an example.
If in a heart chamber you have 100 milliliters of blood when the heart is relaxed, and then after it squeezes, after systole, you move out 65 milliliters of blood, then you have moved out 65 of the 100 milliliters of blood. You've moved out 65%, you've ejected 65%, so your ejection fraction is 65%, and this is considered normal in most cases. 50 to 70% ejection fraction is what we consider normal, but be sure to consult your physician and your heart doctor to find out which ejection fraction is a goal for you.
Causes of Systolic Heart Failure
• Ischemic Heart Disease
• Heart Attack Or Myocardial Infarction
• Hypertension
• Dilated Cardiomyopathy
Diastolic Heart Failure
Now let's talk about diastolic heart failure or heart failure with a preserved ejection fraction. Diastolic heart failure occurs when the heart does not relax well enough in order to fill properly with blood, and yes, it's still congestive heart failure. Now even though in this diastolic heart failure you have a preserved ejection fraction, that doesn't necessarily mean that you are pumping out an adequate amount of blood.
Causes Of Diastolic Heart Failure
• Coronary Artery Disease
• Restrictive Cardiomyopathy
• Aortic Stenosis And Hypertrophic Cardiomyopathy
