We know someone is a heart patient if they have a history of cardiovascular disease, such as a heart attack, stroke, angina, high blood pressure, or other heart-related conditions. Other signs and symptoms may also be present, such as chest pain, palpitations, shortness of breath, dizziness, or fatigue. Additionally, a physical examination may reveal an abnormal heart rhythm, an enlarged heart, or a weakened heart muscle.
Laboratory tests, such as a blood test, urine test, or imaging tests, such as an electrocardiogram (ECG), echocardiogram, or stress test, may also be used to determine if someone is a heart patient. The ECG is a test that records the electrical activity of the heart, while the echocardiogram is an ultrasound of the heart that can detect abnormalities in the heart's structure or function. A stress test can help detect ischemia, which is when the heart doesn't get enough oxygen.
Finally, a cardiologist may order additional tests, such as a cardiac catheterization, angiogram, coronary angiography, or cardiac MRI, to further evaluate a patient's cardiovascular health. These tests can provide more detailed information about the size and shape of the heart, as well as any blockages in the coronary arteries and other heart structures.
Ultimately, the diagnosis of a heart patient depends on the results of the tests mentioned above, as well as the patient's medical history and symptoms.
