What Is Heart Failure?

Heart failure develops because the heart muscle becomes weak or loses the ability to pump normally. The Ejection Fraction (EF) is a percent that lets us know how the heart is squeezing (normal is 60%). If the heart isn’t “squeezing” well to get enough blood to your body, you have heart failure with a reduced ejection fraction (EF < 40%). If the heart can’t “relax” to fill with enough blood between contractions, you have heart failure with preserved ejection fraction (EF > 50%). Heart muscle weakening and damage is often called cardiomyopathy, which literally means “heart muscle disease.”

Symptoms of heart failure
Heart failure interferes with the kidney’s normal function of eliminating excess sodium and waste products from the body. In congestive heart failure, the body retains more fluid, yet not all heart failure patients retain fluid. Here are the symptoms of heart failure:

1.Shortness of breath during daily activities.
2.Having shortness of breath when lying down or sleeping.
3.Weight gain with swelling in the feet, legs, ankles, or stomach.
4.Generally feeling tired ...
... or weak.
What causes heart failure?
Heart failure is most often caused by other conditions, such as atherosclerosis that is blockages in heart vessels, heart attack, high blood pressure, heart valve problems, genetics, and alcohol or drug abuse. Sometimes the damage occurs for no known reason. This is called idiopathic cardiomyopathy (idiopathic means “no known cause”) and many with this find that heart failure runs in their family.
Risk factors for heart failure
Health conditions that are left unrecognized or untreated will increase the lifetime risk of developing heart failure. Some of these diseases include:

1.Coronary heart disease that is blockages in the heart vessels (the most common type of heart disease) and heart attacks
2.High blood pressure
3.Diabetes
4.Obesity
5.Unhealthy behaviour can also increase your risk for heart failure, especially for people who have one of the diseases listed above.
Unhealthy behaviour includes:

Smoking or using tobacco
Excessive alcohol intake
Eating foods high in fat, cholesterol, and sodium
Not getting enough physical activity
Treating heart failure
Early diagnosis and treatment can improve the quality and length of life for people who have heart failure. Treatment usually involves taking medications, getting daily physical activity, and reducing the salt or sodium you eat in your diet. People with heart failure need to track their weight and symptoms each day so that they can discuss these symptoms with their health care team.

Heart failure management is a treatment strategy that can improve your heart function, reduce your symptoms, and lengthen your life. The strategy combines several treatments, including lifestyle changes, medications, and heart procedures.

The last couple of years have been exciting in having newer medications we can offer to patients with the weak heart muscle. These add to our other well-proven medications that can really help improve heart function in many people, reduce hospitalizations and improve surviving heart failure.

Some patients with heart failure may need surgery or procedures to open blocked heart arteries, or open-heart surgery. They may need heart valves fixed or replaced. Many often need procedures to help reduce heart rhythm abnormalities. Some patients with advanced heart failure may need a heart transplant or mechanical heart pump.

Living with heart failure
There are five things patients diagnosed with heart failure need to do every day at home to manage their heart failure. Follow — these basic steps:

1.Medications: Take your medications as prescribed by your doctor and heart care team, let them know if you don’t tolerate your medications and don’t run out of them.
2.Activity: Stay active every day, do what you can to keep your body strong.
3.Weight: Weigh yourself each day, recognize when changes in your weight mean you are retaining more fluid.
4.Diet: Follow your diet, which means low salt (< 2 grams per day) and limit fluid intake (< 2 litres per day).
5.Symptoms: Recognize your symptoms and know when to call for help.
