This is why Cao Dong's first impression of observing this pathological section is myocardial necrosis section. It is true that one characteristic of myocardial fibrosis is cardiomyocyte death.

Dr. Cao Dong's main job is a clinician, and his speech is more simple and straightforward.

If scientific research requires in-depth academic discussion, we cannot simply say myocardial fibrosis, nor can we say that it is a myocardial necrosis section. The exact statement should be a pathological description. If the patient is diagnosed on this section, we cannot simply say that myocardial necrosis section.

The first point to be clear is that myocardial fibrosis is a pathological diagnosis term, not a disease name. It is actually divided into two types. One is reactive fibrosis, which occurs around the blood vessels and is a lesion in which the myocardial muscle responds to myocardial load and inflammation.

Through this definition, we can know that this pathological lesions usually occur in patients with myocardial load or inflammation, such as hypertrophic cardiomyopathy, left ventricular hypertrophy, aortic stenosis, myocarditis and other patients.

Recalling the cases we mentioned before, it can be roughly inferred that patients with cardiomyopathy with valvular disease are expected to have this lesion. The reason why there was no emphasis before is that this examination cannot be performed in vivo, and a myocardial biopsy can only be performed. Myocardial biopsy around the blood vessels is not easy to do and the potential examination risks of the patient should be considered.

Now let’s talk about the significance of scientific research. Doing pathological analysis after death is like a hindsight, but thorough research on the pathogenesis can bring good news to other patients. It can be said that each patient is benefiting future patients at the expense of their own. Human medicine is the most demonstrating the righteousness of mankind and the true meaning of a community with a shared future.

Another type of myocardial fibrosis is the response to cardiomyocyte death mentioned above. Repair scar formation after myocardial fibrosis is called repair fibrosis. It often occurs not around the blood vessels, but in the myocardial interstitial. The corresponding common type of patient is patients with myocardial infarction and myocarditis.

In specific clinical cases, two types often occur in cases where ventricular remodeling occur together. For example, patients with myocardial infarction, the peripheral area of ​​the repair scar is composed of reactive fibrosis and hypertrophic cardiomyocytes that surround the scar area.

Regarding the great harm of myocardial fibrosis, you can directly refer to Xiao Shugang for example.

Let’s talk about this pathological section, which is very rare. Patients with myocardial fibrosis after several days of myocardial infarction will still have a little granulation tissue on the edge.

"It is possible that the part it takes is not right," said Teacher Yuan Fang.

If you do pathological sections, you must select the appropriate lesions to do it. If the position is not accurate, it may not represent the pathological characteristics of the entire human organ. What Mr. Yuan Fang said makes sense.

What Cao Yudong needs to correct is: "There is a possibility of what you said. But if not, we might have to consider other causes and diagnoses."

All aspects should be considered when discussing.

In fact, heart disease is mostly pathological characteristics of myocardial fibrosis. Looking back at the examples of myocardial fibrosis patients, almost all types of heart disease patients are covered soon.

Cold knowledge has arrived, and patients such as drowning may develop myocardial fibrosis.
