Patients with congestive heart failure have a high incidence of sudden cardiac death that is attributed to ventricular arrhythmias. The mortality rate in a group of patients with class III and IV heart failure is about 40% per year, and half of the deaths are sudden.
Most people with end-stage heart failure have a life expectancy of less than 1 year. 4. The leading causes of heart failure are diseases that damage the heart, such as heart disease, high blood pressure, and diabetes.
Although it can be a severe disease, heart failure is not a death sentence, and treatment is now better than ever. When this happens, blood and fluid may back up into the lungs (congestive heart failure), and some parts of the body don't get enough oxygen-rich blood to work normally.
Systolic Heart Failure This is the most common cause of heart failure and occurs when the heart is weak and enlarged. The muscle of the left ventricle loses some of its ability to contract or shorten. In turn, it may not have the muscle power to pump the amount of oxygenated and nutrient-filled blood the body needs.
Although heart failure is a serious condition that progressively gets worse over time, certain cases can be reversed with treatment. Even when the heart muscle is impaired, there are a number of treatments that can relieve symptoms and stop or slow the gradual worsening of the condition.
Cardiomyopathy is disease in which the heart muscle becomes weakened, stretched, or has another structural problem. It often contributes to the heart's inability to pump or function well. Many people with cardiomyopathy have heart failure.
Cardiomyopathy is a progressive disease of the myocardium, or heart muscle. In most cases, the heart muscle weakens and is unable to pump blood to the rest of the body as well as it should. There are many different types of cardiomyopathy, caused by a range of factors, from coronary heart disease to certain drugs.
You may have trouble breathing, an irregular heartbeat, swollen legs, neck veins that stick out, and sounds from fluid built up in your lungs. Your doctor will check for these and other signs of heart failure. A test called an echocardiogram is often the best test to diagnose your heart failure.
Adults age 65 and older are more likely than younger people to suffer from cardiovascular disease, which is problems with the heart, blood vessels, or both. Aging can cause changes in the heart and blood vessels that may increase a person's risk of developing cardiovascular disease.
Chronic heart failure is a long-term condition for which there's currently no cure. However, with medication, many people are able to maintain a reasonable quality of life.
Doctors usually treat heart failure with a combination of medications. Depending on your symptoms, you might take one or more medications, including: Angiotensin-converting enzyme (ACE) inhibitors. These drugs relax blood vessels to lower blood pressure, improve blood flow and decrease the strain on the heart.
The progress of heart failure is unpredictable and different for each person. In many cases, the symptoms remain at a stable level for quite some time (months or years) before becoming worse. In some cases the severity and symptoms become gradually worse over time.
In general, about half of all people diagnosed with congestive heart failure will survive 5 years. About 30% will survive for 10 years. In patients who receive a heart transplant, about 21% of patients are alive 20 years later.
Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body. If this happens, you may feel dizzy, very tired or weak, and short of breath. Sometimes bradycardia doesn't cause symptoms or complications.
Chronic kidney disease can look like heart failure. Both diseases cause fluids to backup, leading to swelling, or edema, in your lower extremities, meaning in your legs and feet. Fluid can build up in the lungs, as well, in both diseases, leading to (once again) shortness of breath.
In end stage heart failure, the body can no longer compensate for the lack of blood the heart pumps, and the heart has limited functional recovery. A person may find it difficult to breathe even when they are resting.
Most often, heart failure is caused by another medical condition that damages your heart. This includes coronary heart disease, heart inflammation, high blood pressure, cardiomyopathy, or an irregular heartbeat.
Tests for heart failure
Tests you may have to diagnose heart failure include: blood tests – to check whether there's anything in your blood that might indicate heart failure or another illness. an electrocardiogram (ECG) – this records the electrical activity of your heart to check for problems.
If you have heart failure, you may not have any symptoms, or the symptoms may range from mild to severe. Symptoms can be constant or can come and go. Heart failure symptoms are related to the changes that occur to your heart and body, and the severity depends on how weak your heart is.
Stress can cause a heart attack, sudden cardiac death, heart failure, or arrhythmias (abnormal heart rhythms) in persons who may not even know they have heart disease.
