Early detection of heart  diseases

What is the early detection of heart disease?

Early detection tests are tests that are done to find a disease before the symptoms begin. The goal of early detection is to detect a disease at its earliest and most treatable stage. To be widely accepted and recommended by doctors, an early detection program must meet a number of criteria, including reducing the number of deaths from the disease.

Screening tests can include laboratory tests to evaluate blood and other fluids, genetic tests that look for inherited genetic markers associated with the disease, and imaging tests that produce images of the inside of the body. These tests are generally available to the general population; However, a person's needs with respect to a screening test are based on factors such as age, gender, and family history.

During an early screening test for heart disease, people who do not have signs or symptoms of coronary artery disease (the most common form of heart disease) could be evaluated to measure:

the amount of cholesterol carried in the blood, known as low density lipoprotein (LDL) (high levels can lead to a blockage of the arteries), and high density lipoprotein (HDL) that absorb cholesterol and take it back to the liver, where it is removed from the body.(heart doctor Oklahoma)

the levels of glucose in the blood which is the amount of sugar present in the blood.
the amount of C-reactive protein in the blood, together with a test called high-sensitivity C-reactive protein assay (hs-CRP). The C-reactive protein appears in greater quantity when there is inflammation or swelling in any part of the body.

blood pressure, the force of blood against the walls of the arteries when the heart beats and when it is at rest .

Depending on the results of the initial screening tests and the presence of risk factors for coronary artery disease, your doctor may recommend additional tests, including:

electrocardiogram (ECG or EKG) , which measures the electrical activity of the heart and reveals information about heart rate and rhythm.

Stress test  consists of walking on an endless treadmill or pedaling on a stationary bicycle increasing levels of difficulty, while controlling the heart rate and rhythm, blood pressure and electrical activity. heart , to determine if there is enough blood flow to the heart when the heart is required. Patients who are unable to exercise are given a medication that makes the heart beat stronger and faster.

echocardiogram, which uses ultrasound to create moving images of the heart. In the stress echocardiogram , an ultrasound of the heart is performed before and after demanding the heart, either through exercise or with a medicine that stimulates the heart.

Cardiac CT for the quantification of calcium, examines the coronary arteries to measure the amount of calcium in the coronary arteries, an indicator of the amount of plaque in the arteries. It is important to note that calcium only measures the presence of plaque. The severity of the narrowing of the coronary artery  due to plaque can not be assessed.

coronary CT angiography (CTA) that uses computed tomography andintravenous contrast (dye) to create three-dimensional images of the coronary arteries, and determine the exact location and degree of plaque accumulation.

Myocardial perfusion imaging (MPI)  where a small amount of radioactive material is injected into the patient and accumulates in the heart. A special camera takes images of the heart while the patient is at rest and after the exercises, to determine the effect of physical and emotional stress on the flow of blood through the coronary arteries and the heart muscle.

coronary angiography by catheter , which takes pictures of the flow of blood through the coronary arteries, allowing the doctor to see any obstruction or narrowing of the coronary arteries. During catheter angiography, a thin plastic tube is insertedinto an artery through a small incision in the skin. Once the catheter is guided to the heart, a contrast medium is injected through the tube, and the images are captured using X-rays.
