In recent years, there have been such rumors almost every once in a while—the heart stent has been phased out in the United States, but China has become a disaster.
In fact, the issue of cardiac stents has always been controversial.
As the most representative and most frequently discussed device in contemporary cardiology, whether it is to praise the advancement of modern medicine or criticize the expensiveness of medical consumables, the small “stent” is typical representative.
Heart stents are unlikely to be eliminated
You must know that a heart stent is a common emergency treatment method for improving the symptoms of coronary heart disease and treating myocardial infarction. It has also been introduced since the 20th century. narrow medical technology.
The principle is to re-expand the narrowed and blocked blood vessels through the placement of stents, relieving the symptoms of myocardial ischemia.
The remarks that cardiac stents, a rescue method for coronary heart disease and myocardial infarction, have been eliminated in the United States, mainly from the debate among American doctors. The point of contention is which type of coronary heart disease patients is suitable for stents. .
Heart stent surgery is not recommended for patients with chronic coronary heart disease without obvious symptoms. Later, this remark was continuously spread and deteriorated, just like the Chinese saying “three people become tigers” generally.
Originally, what the doctor wanted to express was that heart stents could not be abused, but eventually it became that heart stents have been eliminated by the United States.
But in fact, the number of stent surgeries performed in the United States exceeds one million each year, which is significantly higher than that in China.
In acute myocardial infarction, no physician would object to emergency stenting
Whether it is the American Heart Association, the European Society of Cardiology and other guidelines for the treatment of acute myocardial infarction, or the latest Chinese guidelines for the treatment of acute myocardial infarction, it clearly states:
Early, rapid, and complete patency of the infarcted artery is the key to improving outcomes for patients with myocardial infarction.
This also means that, if conditions permit, the patient should be sent to the cardiac catheterization lab as soon as possible for direct PCI, which is currently the most beneficial and life-saving operation.
It cannot be denied that there is a problem of the abuse of stent surgery in our country
Few patients in the United States have more than 3 cardiac stents implanted, but in China, many patients have more than 3 stents, or even 5-10 stents above.
The reason for this is that it is affected by many factors, including the patient’s personal fear of the disease, the doctor’s treatment skills, and financial factors.
Heart stents are not a panacea
Not every patient with heart disease is suitable for cardiac stenting. The premise is that strict implantation indications are required. Usually, stent placement should be considered in these cases:
/p>
First, acute myocardial infarction
If the coronary artery has been completely occluded and a sudden myocardial infarction occurs, angina pectoris, dyspnea, palpitations, and a sense of impending death will occur in a short period of time. Symptoms and may even progress to shock, heart failure and sudden death.
In this case, the patient should go to a qualified hospital for interventional treatment as soon as possible within 6 hours of myocardial infarction, and quickly open the completely blocked blood vessel. The faster the treatment, the better the patient prognosis.
Second, unstable angina
Often, angina pectoris caused by coronary heart disease has a predisposing cause.
Sudden precordial tightening, such as patients with severe mood swings, overwork, or vigorous physical activity , Crush-like pain, the symptoms will be relieved and disappeared after proper rest or oral nitroglycerin.
But if you have recently had unusual angina pectoris.
That is, in rest state, emotional stability, sudden angina pectoris during sleep, no obvious relief after taste nitroglycerin, there is a certain possibility of inducing acute myocardial infarction , in this case, cardiac stenting should be placed.
Third, coronary stenosis
In addition to the above two abnormal symptoms, if the patient does not have myocardial infarction, but the coronary artery has been excessively narrowed, and the degree of stenosis exceeds 70~75%, it also needs to be placed under the advice of the doctor. bracket.
Whether cardiac stenting is required, the patient’s condition and physical condition must first be considered.
If the doctor recommends stent treatment, in most cases, the condition has reached a relatively serious level. In order to minimize the risk of sudden death in the future, follow the doctor’s advice in time. and arrangements are necessary.
