From a patient's perspective, the cardiac catheterization procedure generally begins with the patient registering at the registration desk of the cardiac catheterization lab. The patient is then brought back to the admission unit, where he is prepared for the procedure. This could include placing an IV in his arm as well as prepping and shaving the groin or arm area, depending on where the cardiac catheterization will be performed. After this, the patient is brought back to the catheterization laboratory, generally given mild sedation, and the procedure itself takes generally no longer than 15-30 minutes. The patient is then brought back to the recovery unit, where the catheter is removed. The patient is then observed for several hours and then released. Occasionally, the procedure will be combined with additional therapeutic procedures such as coronary intervention, which will then lengthen the procedure generally by one hour.

What are the chances of reblockage within a coronary stent?
Doctors hope that every coronary stent that they put in will last forever, and generally a lot of them do. Current technology includes a stent with drug coating on it, which helps to prevent reblockage within the stent while the artery is healing.
There have been very low reblockage issues with stent placement. Trials have shown that there is a reblockage rate of around 5% after two to five years. For certain stents, that rate seems to plateau off. For other stents, the rate still seems to climb every year; however, the latest generation of stents has lower reblockage rates.Helpful? 1 person found this helpful.
How do I care for someone with coronary heart disease?
When caring for someone with coronary heart disease, you can help them manage their symptoms by encouraging them to lead a healthy lifestyle. Prepare healthy meals rich in fruits, vegetables, and fiber, and low in sodium. Help them to be active; go for a walk together. If they are on medication to control high blood pressure, cholesterol, or diabetes, be sure they take the medication as prescribed. Understand the warning signs for a heart attack and be prepared to seek help if the person you care for suddenly collapses.
