Treatment of Coronary Artery Disease Anti-cholesterol drugs (e.g. statins) – to reduce the deposits on the arterial walls. Beta blockers – to decrease the cardiac demand for oxygen by means of lowering the heart rate and blood pressure levels. Calcium channel blockers – used in combination with beta blockers.
Which is better CABG or stenting?
For severe heart disease, bypass surgery slightly better than stenting — with caveats, study finds. Among heart-disease patients in a study who received stents, the incidence of a major complication — death, heart attack, stroke or the need for a repeat procedure — was 10.6% after a year.Nov 4, 2021
Is CABG a type of PCI?
Percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are considered revascularization procedures, but only CABG can prolong life in stable coronary artery disease.Mar 5, 2019
When is CABG preferred over PCI?
CABG is the preferred option for left main disease with 2- and 3-vessel disease and a SYNTAX score >32. CABG is also the preferred option even in the presence of a lower SYNTAX score when multiple complex lesions are present and PCI remains technically limited to achieve complete revascularization.
What surgery is done for blocked arteries?
Overview. Coronary angioplasty (AN-jee-o-plas-tee), also called percutaneous coronary intervention, is a procedure used to open clogged heart arteries.

What is a surgical guide for dental implants?
Surgical guides have been in use for years, and some clinicians experienced in placing dental implants still find that a simple surgical guide is sufficient to ensure a successful surgery. However, with the increasing popularity of CAD/CAM technologies, it is becoming more common to use CAD/CAM guided surgery, which utilizes surgical guides that have been manufactured to replicate a digital treatment plan. The need for accurate implant placement is well-known, particularly for achieving the correct angulation of implants in preparation for restoration. As this technology becomes more widely adopted, clinicians can more precisely plan surgery and prosthetic treatment phases, providing patients with better and more predictable treatment outcomes.
How to make surgical guide?
Several different methods can be used when manufacturing a surgical guide. The first is called stereolithography, which consists of hardening layers of a liquid resin bath using a laser. Another similar method is called selective laser sintering, where, instead of a resin bath, a powder bed is used to make the guide. Milling technologies can be used to manufacture a surgical guide from a solid block of material. Conversely, 3D printing technologies are becoming more common. No matter which method you choose, all provide precise transfer of surgery data to the guide.
Why is it important to use CAD/CAM?
It is important to closely monitor treatment to help eliminate the potential for errors. One area where errors might occur is during the data gathering and planning phases. All the data collected should be carefully evaluated to ensure any possible errors are detected before planning the implant treatment. It is essential to precisely carry out the implant positioning and the planning phases for prosthetics. Generally, an implant specialist from the dental laboratory liaises closely with clinicians during the planning phase, and treatment is co-planned before the final plan is approved by the clinician. Despite the advantages of using advanced technology, proper planning and good clinical judgment are still of paramount importance to the success of implant treatment.

What is CAD in medical terms?
Coronary artery disease (CAD) is a condition in which plaque (plak) builds up inside the coronary arteries. These arteries supply your heart muscle with oxygen-rich blood.
How does angioplasty work?
Angioplasty opens blocked or narrowed coronary arteries. During angioplasty, a thin tube with a balloon or other device on the end is threaded through a blood vessel to the narrowed or blocked coronary artery. Once in place, the balloon is inflated to push the plaque outward against the wall of the artery.
What does it feel like to have a CAD?
A common symptom of coronary artery disease (CAD) is angina. Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough oxygen-rich blood. Angina may feel like pressure or a squeezing pain in your chest. You also may feel it in your shoulders, arms, neck, jaw, or back.
How does CAD start?
Research suggests that CAD starts when certain factors damage the inner layers of the coronary arteries. When damage occurs, your body starts a healing process . This healing causes plaque to build up where the artery is damaged. Over time, the plaque may crack and causes blood clots to form in the arteries.
What causes angina in the heart?
When your coronary arteries are narrowed or blocked, oxygen-rich blood can't reach your heart muscle. This can cause angina (an-JI-nuh or AN-juh-nuh) or a heart attack. Angina is chest pain or discomfort that occurs when not enough oxygen-rich blood is flowing to an area of your heart muscle.
What is the most common heart disease?
CAD is the most common type of heart disease. It's the leading cause of death in the United States for both men and women. Lifestyle changes, medicines, and/or medical procedures can effectively prevent or treat CAD in most people.
How old do you have to be to get CAD?
Your risk increases if your father or a brother was diagnosed with CAD before 55 years of age, or if your mother or a sister was diagnosed with CAD before 65 years of age. Although age and a family history of early heart disease are risk factors, it doesn't mean that you will develop CAD if you have one or both.
Why do you need a stent for a clogged artery?
In most cases, a small metal coil called a stent is placed in the clogged artery to help keep the artery open and reduce the risk of it narrowing again. Angioplasty may be done during your cardiac catheterization if your doctor thinks it's the best treatment option for you.
What does a doctor do during cardiac catheterization?
During cardiac catheterization, your doctor will examine images of the inside of your coronary arteries. If cholesterol plaques in these arteries (coronary artery disease) have caused areas of narrowing, your treatment options depend on various factors, including:
What are the symptoms of a narrowed artery?
Symptoms, such as chest pain and shortness of breath. Other medical conditions, such as heart valve disease, diabetes, kidney disease, peripheral artery disease, or prior stroke or heart attack. For some people, medications and lifestyle changes may be the treatment of choice — especially if only one artery is narrowed.
What is the purpose of CAD/CAM?
Its purpose is to transfer the diagnostic and planning of both surgical and prosthetic facets of treatment from the planning stage to the patient during surgery. Being a very precise transfer tool, CAD/CAM surgical guides demand a very precise planning.
What tissues are used for surgical guides?
Consequently, we can observe three main tissues used for support of surgical guides. First, there are teeth supported guides, which make use of the remaining teeth to anchor the surgical guide in place. Then, there are mucosa-supported guides, which will find support on the soft tissues.
What is selective laser sintering?
Also, a similar method, known as selective laser sintering, uses a powder bed instead of a resin bath to manufacture the guide. Another technique uses 3D printing to literally print out the guide. There is also the use of milling technologies to manufacture the final product from a block of material.
What is the information needed to make a surgical guide?
First there is the radiological data, which is obtained from a cone-beam computed tomography.
Can dental laboratories make surgical guides?
There are countless dental laboratories and companies who can produce a CAD/CAM surgical guide, each having different designs and materials. Nonetheless, the very first step in this process is the transmission of the planning datasets to the manufacturing party so it can design and create the guide.
What happens if surgery is not an emergency?
If surgery is not an emergency, the decision-making process becomes more complex. In this situation, the clinician should follow a systematic approach that incorporates the inherit risk of the surgery with the individual’s risk of cardiovascular complications and functional status.
What is preoperative assessment?
For patients undergoing noncardiac surgery, preoperative assessment and perioperative management may be the first comprehensive evaluation of the patient. As such, it should be used as an opportunity to provide optimal medical therapy and minimize long-term risk of cardiovascular disease.
What is a thorough patient history?
A thorough patient history will help elucidate the severity of known cardiac conditions, including ischemic heart disease, heart failure, valvular heart disease, or significant arrhythmia. Special attention should be placed on the stability of coronary syndromes, history of syncope or presyncope, prior history and timing of MI, and presence of implantable devices such as pacemakers or defibrillators.
Is a chest radiograph necessary for perioperative risk assessment?
Routine radiologic imaging for perioperative risk assessment is not necessary. However, if decompensated heart failure is a concern, plain radiographs of the chest in both posterior-anterior and lateral projections can provide corroborating evidence of pulmonary vascular redistribution consistent with congestive heart failure.
Study Questions
What are the long-term outcomes after coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) with drug-eluting stents (DES) in patients with left main or multivessel coronary artery disease (CAD)?
Methods
Data were pooled from the BEST, PRECOMBAT, and SYNTAX trials. The primary outcome was a composite of all-cause death, myocardial infarction, or stroke.
Results
The median follow-up was 60 months, and follow-up was completed for 96.2% of patients. The rate of primary outcome was significantly lower with CABG than with PCI (13.0% vs. 16.0%; hazard ratio [HR], 0.83; 95% confidence interval [CI], 0.69-1.00; p = 0.046).
Conclusions
The authors concluded that CABG, as compared to PCI with DES, reduced long-term rates of the composite of all-cause death, myocardial infarction, or stroke in patients with left main or multivessel CAD.
Perspective
This study reports that CABG, as compared to PCI with DES, significantly reduced the risk of all-cause death, myocardial infarction, or stroke in patients with left main or multivessel CAD. The advantage of CABG over PCI with DES was consistent in most major clinical subgroups, and it continued to accrue over time.
