When you go to the cardiology department for consultation or consultation due to chest pain, chest tightness, panic, breath holding, dizziness. Are you clear about what tests are appropriate for you before your visit? And which aspect of the disease is predicted by each test? 1, vascular heart disease Vascular heart disease is often referred to as coronary heart disease. Simply put, it is a problem with the transportation pipeline that supplies energy to the heart muscle. In most cases, the blood vessels become narrow, which means that the pipeline is not working, and the transported blood and oxygen cannot be adequately supplied to the heart when it needs it, resulting in symptoms such as tightness in the chest, chest pain, tightness in the pharynx, and pain in the left side of the shoulder and the back. (1) The most basic test to find out if this duct is narrowed is an electrocardiogram (ECG), but it is only possible to detect the problem if the ECG is done at the onset of the symptoms; (2) If there is no cardiac discomfort during the examination, a load ECG test, a 6-minute exercise load plate test, or an exercise nuclear myocardial phenomenon test can be done to clarify the situation; (3) A cardiac CTA or coronary artery angiography can be done in serious cases to get a more intuitive picture of the underlying vascularity. (3) In severe cases, cardiac CTA or coronary angiography can be performed to better visualize the basic condition of blood vessels. Structural Heart Disease Structural heart disease is commonly referred to as a structural problem of the heart, including atrial and ventricular septal defects, valve stenosis and closure insufficiency. It is common in children, a small number of young people and some elderly people. Usually there are no symptoms, but only when the area of the defect is large or the valve stenosis or insufficiency reaches a certain level, symptoms related to cardiac insufficiency will appear, such as decreased endurance to activity, chest tightness, panic, shortness of breath, etc. Through the electrocardiogram, chest X-ray, echocardiography, cardiac magnetic resonance examination can be clear. 3.Conduction heart disease That is, the heart beats with problems, including slow heartbeat, fast heartbeat, irregular heartbeat, missed beats, etc. These people will have panic, dizziness, fainting and other uncomfortable symptoms. (1) Electrocardiogram or 24-hour ambulatory electrocardiogram with continuous monitoring is required. (2) Of course, some arrhythmias are not persistent, and such patients may undergo further invasive electrophysiological examination or cardiac buried Holter examination for clarification. Heart disease is not a trivial matter. If you experience any discomfort in your heart, it is recommended that you consult a doctor promptly so as not to miss the best time for treatment. 6 hidden manifestations are actually heart disease Many people do not know that, in addition to severe chest pain, sweating, vomiting, loss of appetite, etc. may actually be signs of heart abnormalities. …… If you find out that you must be thoroughly investigated. 1, unexplained large amount of sweating when you suddenly sweat profusely without a clear reason, to be highly suspicious of heart problems. A large reduction in cardiac output and sympathetic overactivity can cause the sweating symptoms of a heart attack. Sweating can also be caused by diabetics who are in a state of hypoglycemia, or by high levels of thyroid hormones in the blood. Sometimes, a sudden drop in blood pressure and heart rate (vasovagal syndrome) can also cause patients to sweat a lot. 2.Dyspepsia and vomitingIf this occurs without any obvious history of food poisoning, a heart problem should be suspected and an electrocardiogram is needed. 3, Loss of appetiteLoss of appetite can be caused by a variety of reasons, but sometimes, patients with heart failure do suffer from loss of appetite. 4, jaw painTypical angina begins behind the sternum. When the heart muscle doesn’t get enough oxygenated blood, it causes this painful discomfort, and the patient feels pressure in the chest, a burning, squeezing and tightening sensation in this area. Discomfort can also occur in the arms, neck, shoulders, upper abdomen, back or chin. 5. Sudden and Transient Loss of ConsciousnessFainting can be caused by a heart problem and is characterized by a sudden and temporary fainting or loss of consciousness, which recovers naturally. Decreased cardiac output and low blood pressure can cause insufficient blood flow to the brain and cause fainting; fainting can also occur in patients with a sudden very fast or slow heart rate and in patients with severe heart valve stenosis. These patients require first aid to avoid life-threatening situations.
