Blood Test For Congestive Heart Failure

Don't Miss

Preparing For The Bnp Lab Test

BNP Blood Test and its use diagnosing Congestive Heart Failure

You dont need to fast or do anything to prepare for the test. You can get it at any time of day.

Make sure your doctor knows about all medications, vitamins, herbs, and supplements you take. That includes ones that dont need a prescription. These can affect how your doctor interprets your BNP readings.

What Is The Importance Of Ejection Fraction

Your ejection fraction is one way to measure the severity of your condition. If its below normal, it can mean that you have heart failure. Your ejection fraction tells your healthcare provider how good of a job your left or right ventricle is doing at pumping blood. Usually, your EF number is talking about how much blood your left ventricle is pumping out because its your heart’s main pumping chamber.

Several non-invasive tests can measure your EF. With this information, your healthcare provider can decide how to treat you or find out if a treatment is working as it should.

A normal left ventricular ejection fraction is 53% to 70%. An LVEF of 65%, for example, means that 65% of the total amount of blood in your left ventricle is pumped out with each heartbeat. Your EF can go up and down, based on your heart condition and how well your treatment works.

Stage B Treatment Options

While stage A CHF is managed with lifestyle changes, the treatment plan for stage B typically includes taking medications regularly. People at this stage should still make the same lifestyle changes as those appropriate for stage A. However, your doctor may also prescribe additional treatments such as:

  • Angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, if you arent taking any as part of your stage A treatment plan
  • Beta blockers if youve had a heart attack and your EF is 40% or lower, if you arent taking any as part of your stage A treatment plan
  • Possible surgery or intervention as a treatment for coronary artery blockage, heart attack, valve disease, or congenital heart disease

Definition of the congestive heart failure

  • Heart failure is also called congestive heart failure.
  • Congestive heart failure is due to damage to the cardiac muscles.
  • In this condition, the heart cannot pump the blood at a rate needed by the body for the metabolism of the tissues.

Pathophysiology of Congestive Heart Failure

  • The heart failure may be due to:
  • Coronary artery disease . If the coronary arteries become blocked or severely narrowed, the heart becomes starved of oxygen and nutrients.
  • The heart attack damages the heart muscle, resulting in a scarred area that does not function properly.
  • Cardiomyopathy. Damage to the heart muscle causes other than artery or blood flow problems, such as infections or alcohol or drug abuse.
  • High blood pressure leads to overwork of the heart.
  • Other diseases like valvular diseases, thyroid disease, kidney disease, diabetes, or heart defects present at birth can all cause heart failure.
  • Heart failure can occur when several diseases or conditions are present at once.
  • In many pathologic conditions, the onset of heart failure is preceded by cardiac hypertrophy, which is the compensatory response of the heart.

    Congestive heart failure

  • Clinical presentation of heart failure

  • Congestive heart failure is the most common cause of transudative pleural effusion.
  • In treated cases, transudate may change into exudate.
  • Effusion due to congestive heart failure is more on the right side.
  • Classification of congestive heart failure:

    Stage A:

    How Is Heart Failure Treated

    Congestive cardiac Failure

    Your treatment will depend on the type of heart failure you have and, in part, what caused it. Medications and lifestyle behaviors are part of every treatment plan. Your healthcare provider will talk to you about the best treatment plan for you. Treatment is the same, regardless of gender.

    As heart failure gets worse, your heart muscle pumps less blood to your organs, and you move toward the next stage of heart failure. Since you cant move backward through the heart failure stages, the goal of treatment is to keep you from moving forward through the stages or to slow down the progression of your heart failure.

    Stage A treatment

    The usual treatment plan for people with Stage A heart failure includes:

    • Regular exercise, being active, walking every day.
    • Stopping the use of tobacco products.
    • Treatment for high blood pressure .
    • Treatment for high cholesterol.
    • Not drinking alcohol or using recreational drugs.
    • Angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker if you have coronary artery disease, diabetes, high blood pressure, or other vascular or cardiac conditions.
    • Beta-blocker if you have high blood pressure.

    Stage B treatment

    The usual treatment plan for people with Stage B heart failure includes:

    Stage C treatment

    The usual treatment plan for people with Stage C HF-rEF includes:

    If the treatment causes your symptoms to get better or stop, you still need to continue treatment to slow the progression to Stage D.

    What Are The Complications Of Heart Failure

    Some of the complications from heart failure include:

    • Irregular heartbeat.
    • History of taking drugs that can damage your heart muscle, such as some cancer drugs.

    Stage B

    Stage B is considered pre-heart failure. It means your healthcare provider has given you a diagnosis of systolic left ventricular dysfunction but youve never had symptoms of heart failure. Most people with Stage B heart failure have an echocardiogram that shows an ejection fraction of 40% or less. This category includes people who have heart failure and reduced EF due to any cause.

    Stage C

    People with Stage C heart failure have a heart failure diagnosis and currently have or previously had signs and symptoms of the condition.

    There are many possible symptoms of heart failure. The most common are:

    • Shortness of breath.
    • Need to urinate while resting at night.
    • Rapid or irregular heartbeats .
    • A dry, hacking cough.
    • A full or hard stomach, loss of appetite or upset stomach .

    There may be times that your symptoms are mild or you may not have any symptoms at all. This doesn’t mean you no longer have heart failure. Symptoms of heart failure can range from mild to severe and may come and go.

    Unfortunately, heart failure usually gets worse over time. As it worsens, you may have more or different signs or symptoms.Its important to let your doctor know if you have new symptoms or if your symptoms get worse.

    Physical Exam For Heart Failure

    First, your doctor will want to know if you:

    Your doctor will also do a physical exam. They’ll look for signs of heart failure as well as other illnesses that may have weakened your heart.

    During your visit, your doctor will:

    Theyâll also look at your appearance while you sit, do mild activity, and lie flat. People with mild or moderate heart failure may appear comfortable at rest, but when active, they often become short of breath. Those with heart failure may be uncomfortable if they lie flat for a few minutes.

    Your doctor may check for fluid in your lungs with a stethoscope. People with heart failure may also have neck veins that are larger than normal, swelling of the legs or abdomen, or an enlarged liver.

    Bnp Blood Test Overview

    If your doctor orders a BNP test, you are probably showing symptoms of heart failure. The test measures a hormone called brain natriuretic peptide.

    During heart failure, pressure builds up in the chambers of your heart and creates BNP. When the heart works harder and doesnt pump blood well, it releases this hormone in large amounts. BNP widens your blood vessels to help improve circulation. Thats why higher levels may be a sign of heart failure.

    Emergency departments can get your BNP test results in about 15 minutes.

    Here is information you can use to get a clearer understanding of heart failure and the value of this test. It will help you understand what the results mean and how you can use them to help improve your health.

    Risk Factors And Symptoms

    The blood test that detects heart failure

    Risk factors for cardiomyopathy and heart failure include a family history of coronary artery disease, a previous heart attack, excessive alcohol consumption, drug abuse, and obesity. Certain conditions can also increase risk, including high blood pressure, diabetes, thyroid disorders, a buildup of iron in the heart muscle, and sarcoidosis, which causes inflammation in the bodys organs. Cancer treatments, including radiation and certain types of chemotherapy, may also increase a persons risk.

    In its earliest stages, cardiomyopathy and heart failure may not cause noticeable symptoms. However, as the condition progresses, a person may experience fatigue or shortness of breath, especially with physical exertion. They may also have swelling of the legs, feet, and abdomen, which occurs when the body overproduces fluid in response to a reduction in blood pumped from the heart. Other symptoms include heart palpitations or lightheadedness caused by irregular heartbeats, or arrhythmias.

    Are you aware that your heart, the organ which you usually and casually blame for your unwarranted actions, actually doesnt control your emotions? It, in fact, allows pumping of blood, oxygen, and nutrients throughout your body. It beats over 100,000 times per day and pumps about 1.5 gallons of blood every minute. It keeps itself superactive so that you can keep going. But are you taking enough care of your heart health? Heart disease has become one among the emerging health issues in developing India.As per the WHO, more than four out of five heart disease deaths are due to heart attacks and strokes, and one third of these deaths occur prematurely in people below 70 years of age.Dont let your sedentary lifestyle invite health problems for you.

    What Is The Outlook With Heart Failure

    With the right care, congestive heart failure wont stop you from doing the things you enjoy. Your prognosis, or outlook for the future, will depend on:

    • How well your heart muscle is working.
    • Your symptoms.
    • How well you respond to your treatment plan.
    • How well you follow your treatment plan.

    One study says that people with heart failure have a life span 10 years shorter than those who dont have heart failure. Another study showed that the survival rates of people with chronic heart failure were 80% to 90% for one year, but that dropped to 50% to 60% for year five and down to 30% for 10 years.

    A different study found that people who had heart failure and were discharged from the hospital had expected life spans ranging from three to 20 years, depending on various factors like age and gender. Its important to look at your specific situation when considering your prognosis.

    UNDERSTANDING THE LAB WORK NEEDED TO DIAGNOSE HEART FAILURE

    Blood is usually drawn when a patient starts developing symptoms of heart failure. The reason for lab testing is to see is any other disease are present and contributing to the failure. The other reason to assess for other conditions with bloodwork is because heart failure treatment may be more complicated depending on any other conditions a person has. Some common blood tests used in initial assessment of heart failure include:

    Albumin blood testmeasures the amount of albumin in your blood. Albumin is a protein made by your liver. Albumin helps keep fluid in your bloodstream so it doesnt leak into other tissues. It is also carries various substances throughout your body, including hormones, vitamins, and enzymes. Low albumin levels can indicate a problem with your liver or kidneys.

    ALT -ALT, which stands for alanine transaminase, is an enzyme found mostly in the liver. When liver cells are damaged, they release ALT into the bloodstream. An ALT test measures the amount of ALT in the blood. High levels of ALT in the blood can indicate a liver problem, even before you have signs of liver disease, such as jaundice , a condition that causes your skin and eyes to turn yellow. An ALT blood test may be helpful in early detection of liver disease.

    Complete blood count or CBC is a blood test that measures many different parts and features of your blood, including:

    Different types of iron tests include:

    Tests For Heart Failure

    The doctor may suggest you get some tests to find the cause of your heart failure and see how severe it is.

    Blood tests. They look at your kidney and thyroid gland health and measure your cholesterol levels. They also check if you have anemia, which happens when you don’t have enough healthy red blood cells.

    B-type natriuretic peptide blood test. Brain natriuretic peptide is a substance your body makes. Your heart releases it when heart failure develops. It is turned into N-terminal pro-brain natriuretic peptide . Levels of both can be higher in people with heart failure. These tests can be used to help figure out if a patientâs shortness of breath is caused by heart failure.

    Chest X-ray. This shows the size of your heart. It also lets your doctor know if there’s a buildup of fluid around your heart and lungs.

    Echocardiogram. This test, often called an “echo,” shows your heart’s movement. During this exam, your doctor places a wand on the surface of your chest. It sends ultrasound waves that show pictures of your heart’s valves and chambers. Those images let your doctor look at how well your ticker is pumping.

    Your doctor may combine an echocardiogram with tests called Doppler ultrasound and color Doppler to check blood flow across your heart’s valves.

    Cardiac catheterization. This measures whether you have clogged heart arteries . Your doctor may also call it coronary angiogram.

    Signs Of Heart Failure

    Signs associated with heart failure depend on the causes of the heart failure and the heart chamber that is affected. With left-sided congestive heart failure, signs are associated with a backup of pressure in the vessels delivering blood to the left ventricle. This causes fluid to accumulate within the lungs . Coughing, difficulty breathing, and exercise intolerance are the most common signs. Many dogs with left-sided congestive heart failure faint due to lack of blood flow and oxygen to the brain. They may also have a low heart rate and low blood pressure and may collapse. Dogs with left-side congestive heart failure often breathe faster than healthy dogs. Your veterinarian may direct you to count the number of breaths your dog takes within a minute when it is sleeping or resting. This sleeping respiratory rate can then be regularly monitored to identify early heart failure and assess whether your dog is responding to treatment.

    Right-sided congestive heart failure results in increased pressure in the vessels delivering blood to the right atrium and the bodys veins and capillaries. This may cause fluid to build up in the abdomen , the chest cavity, liver, and the limbs.
