Can Blood Test Detect Heart Attack

Don't Miss

Will Your Insurance Pay

New blood test could help prevent heart attacks

Compared with the $760,000 it costs to treat a single heart attack patient, these tests are cheapbut some insurers won’t pay for them. “The system rewards doctors who do bypasses but doesn’t pay for prevention,” says Arthur Agatston, MD. Many companies are coming around: Most will pay for the stress EKG, blood glucose, and advanced cholesterol tests. Some will cover the gene tests and CIMT. Cardiac calcium scoring usually isn’t covered. Call your carrier beforehand to find out what it will pay for and what your co-payment will be.

Blood Test To Diagnose Heart Attacks Is Flawed Warn Researchers

One in 20 patients had test levels higher than recommended limit – study results could help to avoid misdiagnosis and inappropriate treatment

The blood test used to diagnose a heart attack in patients admitted to hospital can be misleading, warn researchers in a study published by The BMJ today.

Of 20,000 consecutive patients undergoing blood tests at University Hospital Southampton, one in 20 had levels of troponin greater than the manufacturers recommended upper limit. But in most of these patients were being seen for other conditions and so there were no clinical signs or symptoms of a heart attack.

Troponin levels also differed according to several factors such as age, sex and whether inpatient or outpatient.

The researchers, led by cardiologist Professor Nick Curzen, say these results highlight the need for medical staff to interpret troponin levels carefully in order to avoid misdiagnosis of a heart attack and inappropriate treatment.

Current guidelines recommend troponin tests to help exclude or diagnose a heart attack. Manufacturers of troponin tests provide a recommended level based on values from a few hundred healthy individuals.

This recommended level is used as the upper limit of normal . In other words, if the value of troponin is above the 99th percentile, that is considered to be abnormal, and would indicate a heart attack in appropriate clinical circumstances.

The average age of participants was 61 and 53% were women.

What Are The Implications

This meta-analysis generally supports NICE recommendations around the use of the high sensitivity troponin test in people with a suspected heart attack but without the classic ECG signs of ischaemia.

Although it is not reliable less than three hours after the onset of pain, where the ECG is normal the new high sensitivity assay may reduce waiting times and avoid unnecessary hospital admissions and associated costs.

Risk Factors You Can Control

The major risk factors for a heart attack that you can control include:

Some of these risk factorssuch as obesity, high blood pressure, and high blood sugartend to occur together. When they do, it’s called metabolic syndrome.

In general, a person who has metabolic syndrome is twice as likely to develop heart disease and five times as likely to develop diabetes as someone who doesn’t have metabolic syndrome.

Anxiety And Depression After A Heart Attack

New blood test could rapidly detect if you

After a heart attack, many people worry about having another heart attack. Sometimes they feel depressed and have trouble adjusting to new lifestyle changes.

Talk about how you feel with your health care team. Talking to a professional counselor also can help. If you’re very depressed, your doctor may recommend medicines or other treatments that can improve your quality of life.

Joining a patient support group may help you adjust to life after a heart attack. You can see how other people who have the same symptoms have coped with them. Talk with your doctor about local support groups or check with an area medical center.

Support from family and friends also can help relieve stress and anxiety. Let your loved ones know how you feel and what they can do to help you.

What Does The Test Show

When your heart muscle has been damaged, which can happen during a heart attack, your body releases substances into your blood. Blood tests can measure the levels of these substances and show if, and how much of, your heart has been damaged.

The most common blood test after a heart attack will check levels of a protein called troponin in your blood.Blood tests are also done to measure the level of other substances in your blood, such as blood fats and minerals.

The blood test can also show how your bodys organs are functioning, such as your kidneys, liver or hormone-producing glands. This information helps to guide treatment and diagnosis.

Utilizing Blood Tests Ecg And Imaging Studies

A heart attack, referred to medically as myocardial infarction, occurs when the blood flow to a part of the heart suddenly slows or stops, causing damage to the heart muscle. Roughly 735,000 heart attacks occur in the United States each year. Of these, around 26% of women and 19% of men will die as a result of the event within a year, according to the American Heart Association .

Knowing the signs and obtaining a timely diagnosis can increase your chances of survival and recovery.

Signs Symptoms And Complications

Not all heart attacks begin with the sudden, crushing chest pain that often is shown on TV or in the movies. In one study, for example, one-third of the patients who had heart attacks had no chest pain. These patients were more likely to be older, female, or diabetic.

The symptoms of a heart attack can vary from person to person. Some people can have few symptoms and are surprised to learn they’ve had a heart attack. If you’ve already had a heart attack, your symptoms may not be the same for another one. It is important for you to know the most common symptoms of a heart attack and also remember these facts:

  • Heart attacks can start slowly and cause only mild pain or discomfort. Symptoms can be mild or more intense and sudden. Symptoms also may come and go over several hours.
  • People who have high blood sugar may have no symptoms or very mild ones.
  • The most common symptom, in both men and women, is chest pain or discomfort.
  • Women are somewhat more likely to have shortness of breath, nausea and vomiting, unusual tiredness , and pain in the back, shoulders, and jaw.

Some people don’t have symptoms at all. Heart attacks that occur without any symptoms or with very mild symptoms are called silent heart attacks.

Why Do Some Blood Tests Require Fasting

Heart Attack Blood Test: Troponin

Everything you eat and drink contains vitamins, proteins, and other nutrients that can cause the related levels in your blood to temporarily spike or drop.

Fasting for 812 hours helps ensure that blood test results are free from these variables, making your test results as accurate as possible.

Some common tests that may require fasting include:

  • cholesterol tests

Results may take anywhere from a few hours to a few days to become available. Heres an overview of how long some common tests may take:

  • complete blood count : 24 hours
  • basic metabolic panel: 24 hours
  • complete metabolic panel: 2472 hours
  • lipid panel: 24 hours.

This can depend on the specific lab where you get tested or how many tests you get done at once. If you order multiple tests, you may not get the complete results until all of the tests are completed.

Sometimes a lab will only release results to your doctor, who reviews them and then releases them to you.

Half Of Heart Attacks And Strokes Occur In People With Normal Cholesterol

Traditionally, medical providers have checked patients for certain standard risk factors, such as high blood pressure, high cholesterol, and a family history of CVD. However, many heart attacks and strokes occur in people who lack these factors. For example, the AHA reports that about 50 percent of these events strike people with normal cholesterol levels.

For a more comprehensive assessment of cardiovascular health, Dr. Doneen now offers the new tests, which she uses in conjunction with inflammation testing and other CVD screening methods in her practice. The new tests help us further fine-tune risk assessment and prevention strategies for our patients.

Here is a closer look at the three blood testsand why Dr. Doneen recommends them to her patients.

When Do I Do If Someone Else Has A Heart Attack

An easy-to-use device called an AED is available in many public places and can be used by almost anyone to treat cardiac arrest. This device works by shocking the heart back into a normal rhythm.

Hereâs how to use an AED:

1. Check responsiveness

  • For an adult or older child, shout and shake the person to confirm whether theyâre unconscious. Do not use AED on a conscious person.
  • For an infant or young child, pinch their skin. Never shake a young child.
  • Check breathing and pulse. If absent or uneven, prepare to use the AED as soon as possible.

2. Prepare to use AED

  • Make sure the person is in a dry area and away from puddles or water.
  • Check for body piercings or outline of an implanted medical device, such as a pacemaker or implantable defibrillator.
  • AED pads must be placed at least 1 inch away from piercings or implanted devices.

3. Use AED

For newborns, infants, and children up to age 8, use a pediatric AED, if possible. If not, use an adult AED.

  • Turn on the AED.
  • Plug in connector, if necessary.
  • Make sure no one is touching the person.
  • Push the âAnalyzeâ button.
  • If a shock is advised, check again to make sure no one is touching the person.
  • Push the âShockâ button.
  • Start or resume continue compressions.
  • Follow AED prompts.

4. Continue CPR

Advanced Lipid Profile And Lipoprotein Test

How They Work: Unlike the traditional cholesterol blood test, which measures total cholesterol, HDL, LDL, and triglycerides, the advanced test also looks at particle size. This is important because some particles are big and fluffy, so they tend to bounce off artery walls as they travel through the body. Others are small and dense, meaning they can penetrate the artery lining and form clumps of plaque. The Lp blood test analyzes a specific type of cholesterol that can triple heart risk.

Cost: $19 each

Duration: 5 minutes

Why They’re Heart Smart: Sizing up your particles gives a clearer picture of heart risk than the conventional test: Having a lot of large particles cuts risk, while small ones raise it. The more Lp you have, the worse it is tooit makes LDL particles extra sticky, so they cling to the lining of blood vessels, causing plaque and clots.

Get Them If: You have a family history of heart disease.

What the Results Mean: “You do not want more than 15% of your particles to be the small, dense type,” says Dr. Agatston. For Lp, levels above 30 mg/dl put you at increased risk.

Next Steps: If you have small particles, your doctor may prescribe a drug to increase their size, most likely a fenofibrate or niacin , along with a healthy diet and exercise. Niacin is also among the best treatments for high Lp.

Can Blood Tests Detect Blocked Arteries

Irish scientists develop 13 blood test which can detect ...

Blood tests are used to find out your risk of heart and blood vessel disease.

Elevated levels of substances in your blood, including fats such as cholesterol and triglycerides, proteins and glucose can increase your risk for blocked arteries, known as atherosclerosis. Liver blood tests can also indicate the narrowing of arteries.

If blood tests suggest a high risk of blocked or narrowed arteries, then your doctor will request further cardiology tests to confirm this.

Testing: What To Expect

The hours following a heart attack can be scary and confusing. Your medical team may be incredibly busy and focused, and hard-pressed to explain everything thats happening.

You and your caregivers are sure to have questions. You may wonder about the tests and procedures that are being performed.

In the section below, youll find descriptions of the kinds of diagnostic procedures you may encounter as your doctors strive to identify the underlying causes of your heart attack.

The Blood Test That Confirms A Heart Attack

In the Enhanced Cardiac Access Suite at Capital Cardiology Associates is a sign that reads, When its your heart it just cant wait.

Many heart attacks surface a month in advance, the symptoms go undetected until the individual experiences common indicators like chest pain or pressure. Our ECA Suite is located on the 4th floor of our Corporate Woods office and is the only Capital Region walk-in cardiac clinic. It was specifically designed to serve patients and non-patients who need attention for chest pain, shortness of breath, palpitations, or rapid heart rate.

Tips For Heart Attack Prevention

The goal after your heart attack is to keep your heart healthy and lower your risk of having another heart attack. Take your medications as directed, make healthy lifestyle changes, see your doctor for regular heart checkups, and consider a cardiac rehabilitation program.

Why do I need to take drugs after a heart attack?

You might take certain drugs after a heart attack to:

  • Prevent blood clots

Other Common Signs And Symptoms

New blood test speeds up heart attack diagnosis

Pay attention to these other possible symptoms of a heart attack:

  • Breaking out in a cold sweat
  • Feeling unusually tired for no reason, sometimes for days
  • Nausea and vomiting
  • Light-headedness or sudden dizziness
  • Any sudden, new symptoms or a change in the pattern of symptoms you already have

Not everyone having a heart attack has typical symptoms. If you’ve already had a heart attack, your symptoms may not be the same for another one. However, some people may have a pattern of symptoms that recur.

The more signs and symptoms you have, the more likely it is that you’re having a heart attack.

Mike Marber, professor of cardiology at King’s College London and head of the UK arm of the research, said: Weve shown that this test is not only just as good as the current test for working out who has had a heart attack, but its also much better at working out who hasnt.

Dr Tom Kaier, one of the lead researchers, said the new test could quickly reassure thousands of patients that they are fine and would help free up valuable hospital beds in A& E departments and wards across the country.

Professor Sir Nilesh Samani of the British Heart Foundation said more research was needed before the current test could be replaced.

But he added: Big heart attacks are often easy to diagnose with an ECG but smaller heart attacks, which are more common and also life-threatening, are more challenging.

A Simple And Highly Sensitive Blood Test Can Detect If You Just Suffered A Heart Attackand This Test Is So Super Sensitive That It Can Detect Even A Mild Heart Attack

The blood test is for an enzymatic protein called troponin. The troponin blood test for heart attack is highly sensitive and is considered the gold standard for determining damage to cardiac muscle.

Cardiac enzymes are chemicals contained within heart cells, says Christopher J. Hanifin, PA-C, who was previously a physician assistant in open heart surgery with Cardiothoracic Surgery of South Bend in South Bend, IN.

Normally, they are essentially undetectable in the bloodstream, continues Hanifin.

When a person suffers a heart attack, cells in the heart die and rupture, releasing these enzymes into the blood where they can be detected.

Diagnosis of a heart attack is usually based upon the detection of elevated levels of these chemicals in the blood.

If you go into an emergency room complaining of current or recent chest pain, the doctor or physician assistant will order a blood draw to check your troponin levels.

So if a patient goes to the emergency department with chest pain and their cardiac enzymes tests are negative, are they in the clear? Not necessarily, says Hanifin.

It takes some time for cardiac enzymes to appear in the blood. If a patient is tested in the early stages of a heart attack, it is very possible that their levels will be within normal ranges.

However, an elevated troponin level alone should not be used to outright diagnose heart attack.

Its never elevated by accident. As mentioned, this blood test is super sensitive.

What Does Current Guidance Say On This Issue

Current NICE guidance on chest pain recommends that patients with a suspected heart attack should receive an ECG and high sensitivity troponin test on hospital arrival. If patients do not have the typical ECG features of a heart attack , a repeat high sensitivity troponin three hours later can confirm or rule out non-ST elevation heart attack.

Troponin measurement is not recommended for people presenting with chest pain who are not clinically suspected of having a heart attack.

Stress Ekg Or Echocardiogram

New Version of Blood Test Can Predict Heart Attacks ...

Stress tests are performed to see how the heart performs under physical stress. The heart can be stressed with exercise on a treadmill or in a few instances, a bicycle. If a person cannot exercise on a treadmill or bicycle, medications can be used to cause the heart rate to increase, simulating normal reactions of the heart to exercise.

During the stress test, you will wear EKG leads and wires while exercising so that the electrical signals of your heart can be recorded at the same time. Your blood pressure is monitored throughout the test. The stress test can be performed together with the echocardiogram, described above.
