According to conventional treatment and relevant standards, this piece of myocardial tissue has been severely damaged. Even if the blood vessels are unblocked and the blood supply to the myocardium is restored, the function of this myocardium cannot be restored 100%. How much it can be restored depends on
See the recovery results of subsequent treatment.
Of course, this is conventional treatment and previous related prognosis standards. With the deepening of our research on heart diseases and the application of some new technologies, we can now also treat these damaged myocardial tissues and make them
Return to a level close to health.
For example, the previously mentioned stem cell transplantation technology is used to treat these damaged myocardial tissue cells to restore them to normal levels. Currently, this technology has been applied in many fields and has achieved very significant results.
of therapeutic efficacy.
In addition to using stem cell transplantation technology, we can also use the biological cell printing technology developed by Haoyu Technology to replace these damaged myocardial tissues through shell surgery, thereby achieving a therapeutic effect.
At present, this technology has been used many times in our medical research center, including by relatives of Mr. Wu. Speaking of this, Director Tong glanced at Wu Hao, and then said to Zhang Jun and the others.
Originally, this should be a private matter and doctors should not mention it. However, Zhang Jun was not an outsider and knew about such things. Therefore, in order to appease the family members and build their confidence, Director Tong gave an example.
Hearing Director Tong's words, Zhang Jun's mother and other relatives all looked at Zhang Jun and Wu Hao. After receiving their nods of confirmation, everyone felt a little more relieved and couldn't help but look forward to this technology.
However, what Director Tong said next poured cold water on them. He said in the meantime: "However, this technology requires surgery, and it requires surgery on the heart to remove the original necrotic parts and then replace them.
Printed cardiac tissue.
Therefore, the risk of surgery is relatively high. Unless necessary, we do not recommend such a surgical plan. And judging from the damage to the patient's myocardial tissue, we do not recommend this surgical method and use stem cell implantation for repair.
Treatment with technology is relatively reliable.”
"Then next, we look at the key areas, which are the coronary arteries of the patient's heart. These are like the bulges of old tree roots. The veins are the tubular arteries and blood vessels of our heart. These blood vessels provide nutrients for our entire heart. Once it becomes narrowed
If so, then the myocardial tissue of our heart will have symptoms of ischemia.
If the stenosis further expands, Mr. Hu said that the atherosclerotic plaque at the stenosis will fall off, which will cause blockage of this blood vessel, causing acute ischemia symptoms in the myocardial tissue extended by this set of arteries, causing the heart to
If it cannot work normally, this is myocardial infarction.
Let’s extract the patient’s cardiac tubular arteries and display them individually.”
As Director Tong slid the transparent tablet on his hand, only a vein similar to a tree root remained on the big screen, which was the patient's tubular artery.
And soon the tubular artery became translucent, allowing people to see the blood flow inside.
"Please see, the inner wall of a normal and healthy blood vessel is very smooth, just like the new water pipe we bought. With age and some diseases, the inner wall of the blood vessel will accumulate some sediment, or because of some
The stimulation of the disease causes atherosclerosis in these tubular arteries. Many of these atherosclerotic plaques will accumulate on the inner walls of the blood vessels. As more and more plaque accumulates, the inner walls of the blood vessels will become narrow, thus blocking the flow of blood.
flow, this is myocardial ischemia.
If disease, exercise, or emotional intensification will cause the heartbeat to accelerate and the blood flow rate of the heart blood vessels to increase, this will cause the hardening and loss of elasticity of the blood vessel walls where these atherosclerotic plaques accumulate to split, which will cause the inside to
The outflow of atherosclerotic plaque is blocked in a narrow location.
The platelets in the blood will automatically detect the damaged location of the blood vessel, so they will coagulate urgently to stop the bleeding. As more and more platelets aggregate, the narrowed location will become even narrower, or completely
Blockage. More narrowing will cause angina pectoris, and blockage will cause myocardial infarction. Compared with the former, myocardial infarction is more dangerous and often life-threatening, so it must not be taken lightly.
This is why even many patients with stent implantation need to take lifelong medication, which is to suppress the number of platelets in the patient's body, thereby reducing the continued accumulation of platelets in tubular arteries, especially in stenotic locations and at stent implantation locations, causing
The blood vessels continue to narrow.
This method can of course inhibit further stenosis of the patient's tubular arteries, but it will also bring about some new problems. I won't talk about the side effects of the drug. It is said that as the platelets in the blood vessels are inhibited, it will cause the patient's
The wound is very difficult to heal.
Once a patient is seriously injured, he or she may suffer from severe blood loss due to lack of platelets, which may be life-threatening.
Through this digital 3D imaging model of the patient's cardiac tubular arteries, we can clearly see the five severe stenosis locations in the patient's tubular arteries, as well as the locations of blockages in two of them.
We can see that these two positions are located at the front end of the tubular artery. Among them, point A is the most severely blocked. It has been completely blocked and no blood flows out.
At point B, the blood vessel blockage has reached 97%, which is considered a serious blockage, almost completely blocked. The remaining three stenotic positions are all around 60 to 70%, which is already
It can be regarded as severe coronary heart disease.
As for the rest, they are all small stenosis, about 30 to 40%. Of course, this cannot be taken lightly. Because the patient's blood lipid level is relatively high, the risk of blockage is still very high. Basically
More than ten times that of ordinary people.”
At this introduction, Director Tong focused on observing Zhang Jun and his family members, and then continued: "According to conventional therapy, we need to put stents in these narrow positions, but because there are many narrow positions in patients, stents are used.
More.
Although it cannot reach the nine mentioned by the hospital there before, it is still necessary to implant at least seven stents to stabilize the condition. No matter what kind of stent it is, even the nano-stent developed by our Haoyu Technology is still needed.
Take medication for life.
Depending on the condition, we cannot guarantee that the location where the stent is implanted will not be blocked again, or that there will be no blockage inside the stent."
