The functioning of the heart totally depends upon the supply of coronary blood vessels to your heart. The richer the supply of blood to the heart the more fit the functioning of the heart. If there is any obstruct in the coronary blood supply then the functioning of the heart will slow down and cause coronary heart disease. A cardiac stent is a technique of heart surgery that is used to narrow the coronary artery for a proper supply of blood to the heart. In case of a heart attack, it can be used to flow the speed of the blood to the heart. Cardiac stents are made up of metal coils that run down the artery and open up space for the flow of blood. It used expandable coils for treating the cardiac disease. The doctor uses this technique for coronary angioplasty surgery. This takes place with the help of a device that is capable of opening up the artery for a short time.
Changing of heart stent:
The necessity of keeping a heart stent is only to the fluidity of the blood inside the arteries. But once the surgery conducted then it is mandatory to remove the stent and replace it with the new one. The following reason will help you to know about the changing of heart stent:
- Heart tissue damage: The patient needs to for regular check-ups once they go with heart stent surgery. When the efficiency of working for the stent decreases then less blood gets supplied to the muscle of the heart. This results in less supplying oxygen in the muscle of the heart and causes damage to tissue. In this situation, we need to change the heart stent as per the demand of the situation.
- Severe coronary intervention: It is the situation when a varying type of heart stent is not able to hold the artery for a longer time. In such cases, heart stent with wider size is preferred for allowing a little more volume of blood to pass through the arteries. The surgery for severe coronary intervention should be followed with proper procedure otherwise it may lead to severe bradycardia or heart choke.
- Replacement: The effect of the following tube can last up to 6 months. Heart stent is not a permanent cure for the heart. But still, it is a life-saving process for those who have the most chances of having severe heart attacks. It is this necessary to replace the hollow tube with the another for balancing the functioning of the heart in the diseased condition and helping in saving the life of the patient. If the replacement can’t be done at the given time intervals then it may have chances of blockage of the blood tissue and condition become worse.
- Cholesterolemia: It will be better if you stop eating more amount of fatty acid and oils. Consuming more cholesteric food then made larger fat deposition inside the body vessel. This will obstruct the flow of blood even if you are using a heart stent. So, try to take control of the food you are eating and follow a proper diet from the doctor. If the problem of cholesterolemia persists before 6 months of the surgery then you need to again so for the surgical method for balancing the cholesterol in the body.
- DES: Drug-Eluting Stents are also a method for reducing the obstruction if the flow of blood. It uses metal-containing drugs like paclitaxel that increases the flow of blood in the arteries and thus saves the surgical method of heart stent. If the drug is showing some adverse reaction in the patient then there is the necessity for changing the heart stent quickly and follow some different methods for maintaining the fluidity of blood.
- Age effects: When the age grows older the risk for replacement also goes on increasing. At older ages, the myocardial muscles are not able to pump blood in a balanced manner. In such cases, using treatment measures line heart stent also doesn’t give proper results as the increasing flow of blood will only pass the blood to the heart. The ventricles of the heart should also be ready to pump it out from the chambers. In most of the cases, there is no problem seen in the first year if the treatment. The problem arises when the obstruction rate is even higher even after the treatment. This spending can only give support to the patient for a maximum of 5 years. Then it depends upon the age and factors of the body like how it is adapting with the artificial metallic stents. The risk factors are especially seen among 1 to 2% of the patients.
