Blood Test For Heart Failure: Diagnosis of Heart Failure By Testing Blood

This article aims to clarify a blood test for heart failure: everything you need to know. Various tests are done to diagnose heart disease treating the patient. Tests are done to determine the chest discomfort and if the heart is not working efficiently as it does daily.

A blood test is one of the important tests for diagnosing Heart Failure. Detection of heart disease can save a life. Various tests are done to diagnose heart failure disease as:

  • Blood Test
  • Urine Test
  • B-type Natriuretic Peptide (BNP) Blood Test
  • Chest X-ray
  • Echocardiogram
  • Electrocardiogram
  • Radionuclide Ventriculography
  • Cardiac MRI
  • Exercise Stress Rate

Blood Test Process For Heart Failure

Standard amount of cholesterol in blood is 200 milligram per deciliter (mg/dL) or 5.2 (mmol/L) test. A blood test is one of the most effective tests to diagnose heart failure. This test is done to observe kidney function and cholesterol level and to check anemia.

A blood test can observe the patient’s heart health. It helps to determine if the heart is at risk of failure or attack. Some blood tests done by the doctor to diagnose heart failure are as follows:

Cholesterol Test

A cholesterol test is done to determine the lipid or fats in the4 heart. This can show the risk of heart attack or another heart disease. This test also includes some tests of total cholesterol.

It determines the cholesterol level in the blood and shows if the heart is at risk of failure or other heart diseases. A high level of cholesterol increases the risk of heart disease. Total cholesterol should be below 200mg per deciliter (mg/dl) or 5.2 millimoles per liter (mmol/L)

Low-Density Lipoprotein Cholesterol (LDL)

It is called bad cholesterol in the blood. Too much cholesterol in the blood may cause plaque in arteries and reduce blood flow. LDL cholesterol should be less than 130 mg/dl (3.4 mmol/L). The desirable level is around 100 mg/L.

Patients having records of heart attack, heart stent, or heart bypass surgery have a high risk of a heart attack. So they are suggested to keep the LDL level around 70 mg/L

High-Density Lipoprotein (HDL)

It is called good cholesterol. It helps to carry away bad cholesterol (LDL) and keep arteries open and blood flow more freely. HDL level should be 40 mg/L in men and 50 mg/L in women.


Another type of fat in the blood is triglyceride. If someone contains high triglyceride i9n blood, they eat more cholesterol regularly. This high level of cholesterol is highly responsible for heart disease. So blood test is also done to check the triglycerides level.

Non-HDL Cholesterol

Non-HDL cholesterol is the difference between total cholesterol and HDL cholesterol. This Non-HDL contains cholesterol in lipoprotein particles that are involved in hardening arteries. So blood test is done to see the level of NON-HDL cholesterol for treatment.


The blood test is one of the important tests for diagnosing heart failure. It helps to determine if the heart is at risk of failure or attack. This article discusses various tests that can diagnose heart failure, focusing on blood tests. It explains how these tests work and what they can reveal about a person’s heart health.
