Chapter 3402 [3402] Cold Knowledge

This is why Cao Dong’s first impression when he observed this pathological section was myocardial necrosis. Indeed, a feature of myocardial fibrosis is myocardial cell death.

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

If you want to conduct in-depth academic discussions in scientific research, you cannot simply say that myocardial fibrosis is generalized, nor can you say that the impression is myocardial necrosis slices. The accurate statement should be the pathological description, and if the patient is to be diagnosed on this slice, it cannot simply be said to be a slice of myocardial necrosis.

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 blood vessels and is a pathology in which the myocardium responds to myocardial load and inflammation.

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

Recalling the cases we mentioned before, it can be roughly inferred that patients with valvular cardiomyopathy are expected to have such lesions. The reason why it was not mentioned before is because pathological anatomy cannot be done in vivo for this examination, only a myocardial biopsy can be done. Myocardial biopsies around the vessels are not easy to perform and the potential risk to the patient should be considered.

Now we want to talk about the meaning of scientific research. Doing pathological analysis after death is like an afterthought, but a thorough study of the pathogenesis can bring good news to other patients. It can be said that every patient is benefiting future patients at his own expense, and human medicine is the most important manifestation of human righteousness and the true meaning of a community with a shared future.

Another type of myocardial fibrosis is the above-mentioned response to myocardial cell death. After myocardial fibrosis, reparative scarring is formed, which is called reparative fibrosis. It often occurs not around the blood vessels, but in the myocardial interstitium, and the corresponding common patient type is patients with myocardial infarction myocarditis.

To specific clinical cases, the two types are often mixed together in the cases of ventricular remodeling. As in patients with myocardial infarction, the periphery of the repair scar is reactive fibrosis and hypertrophic cardiomyocytes that surround the scar area.

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

Looking back and talking about this large piece of myocardial fibrosis in this pathological section, I hardly saw anything else, which is really rare. The pathology of patients with myocardial infarction several days later will still have a little granulation tissue on the edge.

"It's possible that this part is not right." Teacher Yuan Fang said.

For pathological sectioning, appropriate lesions should be selected. If the location is not accurate, it may not represent the pathological characteristics of the entire human organ. What Teacher Yuan Fang said makes sense.

What Cao Yudong needs to correct is: "What you said is possible. But if not, we should probably consider other causes and diagnoses."

Consider all aspects when discussing.

In fact, most of the heart disease is the pathological feature of myocardial fibrosis. Looking back at the example of patients with myocardial fibrosis, almost all types of heart disease patients are covered.

The cold knowledge has arrived, including patients such as drowning, myocardial fibrosis may occur.

Thank you for your support! ! Good night folks~ I'm so tired, today's 5th shift.
