What are the indications for a CABG?

What are the indications for a CABG?

The chief anatomical indications for CABG are the presence of triple-vessel disease, severe left main stem artery stenosis, or left main equivalent disease (ie, 70 percent or greater stenosis of left anterior descending and proximal left circumflex artery)—particularly if left ventricular function is impaired.

Does CABG require sternotomy?

The usual incision for coronary artery bypass grafting (CABG) is a midline sternotomy (see the image below), although an anterior thoracotomy for bypass of the left anterior descending (LAD) artery or a lateral thoracotomy for marginal vessels may be used when an off-pump procedure is being performed.

Who is a candidate for CABG?

Who Needs Coronary Artery Bypass Grafting? Coronary artery bypass grafting (CABG) is only used to treat people who have severe coronary artery disease (CAD) that could lead to a heart attack. Your doctor may recommend CABG if other treatments, such as lifestyle changes or medicines, haven’t worked.

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 is the difference between PCI and CABG?

All comparisons of CABG to PCI or medical therapy that demonstrate survival effects with CABG also demonstrate infarct reduction. Thus, CABG may differ from PCI by providing “surgical collateralization,” prolonging life by preventing myocardial infarctions.

Which is better CABG or angioplasty?

Bypass surgery is generally superior to angioplasty. When more than one heart artery is blocked, CABG may also offer better survival rates for people with heart failure.

Which graft is used in CABG?

Internal thoracic arteries (also called ITA grafts or internal mammary arteries [IMA]) are the most common bypass grafts used. They are the standard of care, and the goal is to use these arteries for every patient who has isolated coronary artery bypass surgery.

Why must certain patients with circulatory conditions undergo angioplasty?

Angioplasty is often used when there is less severe narrowing or blockage in your arteries and when the blockage can be reached during the procedure. CABG might be chosen if you have severe heart disease, multiple arteries that are blocked, or if you have diabetes or heart failure.

Who is not a candidate for CABG?

You may not be a good candidate if you have a: Pre-existing condition including an aneurysm, heart valve disease, or blood disease. Serious physical disability including an inability to care for yourself. Severe disease of another organ, such as the lungs or kidneys.

At what point do patients get CABG?

CABG is typically performed only on patients with severe blockages in the large coronary arteries. Based on a number of factors, your doctor will decide if you are a candidate for CABG. Determining factors include presence and intensity of CAD symptoms, as well as the location of plaque buildup.

Which is better CABG or PCI?

From both short and long-term studies, it emerges that in patients with multivessel disease, coronary artery bypass grafting (CABG) is associated with better survival, lower rates of major cardiovascular events (specifically myocardial infarction or stroke) and repeat revascularization as compared with percutaneous …

Why is PCI better than CABG?

All-cause mortality was significantly higher with PCI compared with CABG. Due to the large number of individual data, subgroup analysis was feasible. It showed that in non-diabetic patients with multivessel disease and low (≤22) SYNTAX score, PCI was as safe and effective as CABG.

How are statins used to treat CABG surgery?

Statins have been shown to reduce the progression of native artery atherosclerosis, slow the process of vein graft disease, and reduce adverse cardiovascular events following surgical revascularization. 1,2,16 For many years, statins were administered after CABG to reduce low-density lipoprotein levels to <100 mg/dL.

Which is the best antiplatelet therapy for CABG?

Most importantly, the trial was limited by the use of low-dose aspirin (100 mg daily) in the control arm of the study. Current guidelines 2,3 recommend dual antiplatelet therapy for patients recovering from off-pump CABG, the primary technique used in this trial.

Are there any benefits to taking clopidogrel before CABG?

In the subgroup of 2072 patients who subsequently underwent CABG, the overall benefits of clopidogrel were maintained by the end of the study. In addition, there was a trend to fewer complications prior to surgery whilst awaiting the intervention (5.6% vs 6.7%; number needed to treat (NNT) 90).

When to use anticoagulation for post CABG atrial fibrillation?

The role of anticoagulants in patients who develop post-CABG atrial fibrillation is unclear. Aggressive anticoagulation and cardioversion may reduce the neurological complications associated with this arrhythmia. Early cardioversion within 24 hours of the onset of atrial fibrillation can probably be performed safely without anticoagulation.
