It turns out that a lot of people have had chest pains. Some people think they’re having a heart attack, and more people don’t hear about it. Yes, it can be a sign of coronary heart disease, but it can also be just a trivial chest wall pain, or stomach acid acting up. So, what tests should be done for chest fossa pain caused by angina pectoris? The following is a brief introduction: 1.Electrocardiogram Electrocardiogram is the most commonly used non-invasive test for the diagnosis of myocardial ischemia. Patients whose electrocardiogram is within the normal range at rest may be considered for ambulatory electrocardiogram recording and/or cardiac stress test. 2.X-ray There may be no abnormal findings, but some patients may see changes such as enlarged heart shadow, widened aorta, and pulmonary congestion. 3.Radionuclide Commonly used radionuclides are 201Tl or 99mTc-MIBI, which can make the normal myocardium appear but not the ischemic area. 4.Selective coronary angiography By injecting contrast into the coronary arteries, it can show the obstructive lesions in the left and right coronary arteries and their branches. Although it is an invasive test, it is also the most valuable means of detecting atherosclerotic lesions in the coronary arteries. 5.Intravascular ultrasound imaging is to send a miniature ultrasound probe into the coronary artery through the cardiac catheter, which can simultaneously understand the narrowing of the coronary lumen and the lesion of the wall. 6.Angiography can directly observe the lumen of coronary arteries, especially for thrombotic lesions.
