In Orlando cardiology doctors employ different tests to diagnose coronary artery diseases and vascular diseases. A stress test helps the Orlando doctors to check how the heart works during physical stress. Certain heart related problems are easier to detect when the heart is working hard.

Orlando doctors can check the severity of coronary artery diseases and can also check other problems such as heart valve disorders and heart failure through stress testing.

Coronary diseases occur when the blood vessels that supply blood to the heart muscles become hard and narrow due to plaque deposits. This plaque is built up of cholesterol, fat, calcium and other substances found in the blood. Excessive plaque deposits in the internal walls of arteries obstruct the blood flow.  A person may not normally have any signs or symptoms of heart diseases but when he/she works hard during an exercise, the heart requires additional supply of oxygenated blood. Arteries blocked with plaque fail to supply this blood and this can cause discomfort, pain and breathlessness. This is why it is important to go for a check up and diagnosis of a possible coronary artery disease.

As per experienced FL doctors in the field of cardiology, a stress test can detect following indications that a person’s heart does not get adequate blood during exercise:

Abnormal changes in the heart rate or blood pressure
Symptoms such as breathlessness and/or chest pain
Abnormal changes in the heart rhythm or electrical activity of the heart

During the stress test if the person cannot exercise for as long as what is considered normal for someone his/her age, it may be a sign that adequate blood is not reaching the heart. Proper medication and/or treatment may then be required before the symptoms get more serious. In Orlando doctors at a heart hospital may prescribe blood thinning medicines like aspirin along with other medications to unclog the arteries in such people.

Standard exercise stress tests use EKGs (electrocardiograms) and breathing and blood pressure monitoring to check blood flow in the heart. Imaging stress tests that use echocardiography, radioactive dyes, or magnetic resonance imaging (MRI), show how well blood flows in heart muscle.
