Commonly used medical tests to diagnose heart disease
Examinations of the blood
When your muscle is damaged, such as during a heart attack, your body releases substances into your bloodstream. Blood tests can detect the substances and determine whether or not your heart muscle has been damaged.Blood tests are also used to determine the concentrations of other substances in your blood, such as blood fats (such as cholesterol and triglycerides), vitamins, and minerals.
A vein in your arm is used to draw your blood. The sample is then tested in a laboratory and the results are sent to your doctor, who will explain the findings to you and will cure you through medicine in case your heart requires to have an emergency cure, then the angioplasty will be done right away. The cost of angioplastyin Karachi is around 25000 to 30000 depending upon the hospital and the expertise of the doctor.
Tests
The following tests can be used to help diagnose
or monitor coronary artery disease:
Electrocardiogram (ECG) (ECG or EKG). This simple
and painless test assesses the electrical activity of the heart. It can
indicate how quickly or slowly the heartbeats. Your
provider can examine signal patterns to see if you're having or have had a
heart attack.
Echocardiogram. This test employs sound waves to
generate images of the beating heart. An echocardiogram can demonstrate how
blood flows through the heart and its valves.
A lack of oxygen or a heart attack can cause
parts of the heart to move slowly. This could be a sign of coronary artery disease
or something else.
Stress test with exercise If your symptoms are worse when you exercise, your provider may ask you to walk on a treadmill or ride a stationary bike during your ECG. A stress echocardiogram is a test that is performed while performing these exercises. If you are unable to exercise, you may be given medications that stimulate the heart in the same way that exercise does.
Nuclear stress examination. This test is similar to an exercise stress test, but it includes images in addition to ECG recordings. A nuclear stress test demonstrates how blood flows to the heart muscle at rest and under stress. IV administers a radioactive tracer. The tracer improves the visibility of the heart arteries on images.
CT scan of the heart (cardiac). A CT scan of the heart can reveal calcium deposits and artery blockages. Calcium deposits can cause artery narrowing.
During this test, the dye may be administered
via IV. The dye aids in the creation of detailed images of the heart arteries.
The test is known as a CT coronary angiogram if the dye is used.
Angiogram and cardiac catheterization. A
cardiologist gently inserts a flexible tube (catheter) into a blood vessel,
usually in the wrist or groin, during cardiac catheterization. The catheter is
guided gently to the heart. It is guided by X-rays. Dye is pumped through the
catheter. The dye enhances the visibility of blood vessels in the images and
highlights any blockages.
If an artery blockage needs to be treated, a
balloon on the catheter's tip can be inflated to open the artery. To keep the
artery open, a mesh tube (stent) is typically used.
