What is the most accurate heart disease? The cardiologist tells you

 Occasionally I heard that my relatives and friends had heart disease, or I had some discomfort in my chest. I suspected that I had a heart disease. I always thought about what kind of examination I should do. I would like to do the examination to see if there is any heart disease. A more accurate examination, then what kind of examination is the best examination for heart disease? You'll understand after reading it.

1. The heart is composed of many structures

Since the heart is the power organ of the human circulatory system, it promotes the continuous circulation of blood throughout the body, so we often compare the heart to the engine of the human body. Of course, similar to the principle of the machine, the heart is also composed of multiple components, including the myocardium, valves (the human body has four sets of valves, mitral valve, tricuspid valve, pulmonary artery package, aortic valve), conduction beams, and cardiovascular (coronary) artery). Only when so many structures are organically combined and interlocked can the normal physiological function of a heart be exerted.

2. There are so many diseases with so many structures

Just like a machine will break, there will be problems with the heart structure, which means there will be clinical diseases. For example, heart valves have two main functions. One is to guide the heart's blood flow to a fixed direction when the valve is open, and the other is to block the backflow of blood when the valve is closed, so it is a one-way valve. . Another example is the conduction beam. The reason why our whole heart can contract and relax regularly is the bioelectricity command of the heart. This bioelectricity is generated and transmitted by the leaflet system. There are also coronary arteries, which everyone is more familiar with. Coronary heart disease is caused by clogged coronary arteries.

3. The symptoms of different diseases are quite different

Most patients with heart diseases are only discovered when they have symptoms. Different types of heart diseases have their own characteristics. For example, for heart valve disease, most people come to see the doctor due to exertional asthma; the arrhythmia caused by abnormal conduction bundles often causes palpitation, palpitations, abnormal heartbeat, and syncope; patients with coronary heart disease, the typical symptoms are angina pectoris, rest It will be fine in a few minutes.

4. Different examinations target different diseases

Each type of inspection has its expertise, just like a ruler is used to measure length, scales are used to weigh, and electric pens are used to measure electricity. Do you ask the doctor what to check for heart disease? The doctor must ask you what you are uncomfortable with, and then arrange examinations based on the suspected diseases. You can't do all the examinations. For example, if there is nothing uncomfortable and just want to have a physical examination, sometimes the doctor’s heart auscultation is enough; palpitation, palpitations, suspected arrhythmia, you can take an electrocardiogram; asthma after the activity, heart murmur, you can have a heart color ultrasound; If you suspect coronary heart disease, you can have an exercise stress ECG, coronary CTA, and coronary angiography is also optional, but because it is an invasive examination, it is not done right away and needs specific evaluation.

The structure of the heart is complex and the symptoms are diverse. Common heart-related examinations, such as electrocardiogram, workload electrocardiogram, heart color Doppler ultrasound, chest X-ray, coronary CTA, coronary angiography, cardiac radionuclide examination, cardiac magnetic resonance, etc., have their own strengths. It should be selected according to specific needs, there is no best one.
