Stress tests are one of the key Cardiovascular Diagnostics assessment tools, as they help determine the capacity of the heart to exert itself physically. Unlike resting tests, these assessments mimic conditions under which your heart functions more, making the doctors discover the problems they cannot see when you are relaxed.

In a stress test, the patient either exercises on a treadmill or cycles on a bike with a doctor and nurse watching over such aspects as the heart rate, blood pressure, and breathing. For people who cannot exercise, they can be prescribed medicines to produce the same effect as exercising in the heart. The work is to evaluate the blood flow and oxygenation in the heart during high pressure which may show any abnormalities in the coronary arteries. Stress tests work great for diagnosing diseases like coronary artery disease or arrhythmias or for determining the success of the applied treatments like stents or even bypass surgery.

In this case, they also play a preventive role because they assist in identifying danger signs even without the patient’s presentation of signs and symptoms. These tests can then be useful for people who have come into a certain risky factor such as diabetes, high blood pressure, or a family history of heart disease. Today technological developments have improved the ways to conduct stress tests. Echocardiography or nuclear imaging is often incorporated to define the contractile response of the myocardium to stress, and better visualization of the anatomy of the heart. These advancements have gone a long way in enhancing the rates of correct diagnosis.

Since the stress test depends on an electrocardiogram, one is asked to withhold any food intake for several hours and refrain from taking caffeine or specific medications before the stress test. In most cases, the test is safe, although minor risks are associated with the test, especially for candidates with severe heart conditions which underlines the need for proper supervision by practitioners.
