What is multivessel PCI?

What is multivessel PCI?

Background. In patients with ST-elevation myocardial infarction (STEMI) who have multivessel disease, percutaneous coronary intervention (PCI) for nonculprit lesions (complete revascularization) is superior to treatment of the culprit lesion alone.

Do you do PCI for NSTEMI?

In contrast to St-segment elevation myocardial infarction (STEMI), where immediate coronary revascularization by percutaneous coronary intervention (PCI) for completely-occluded infarct-related artery is a guideline-mandated treatment, in non-ST-segment elevation myocardial infarction (NSTEMI) the optimal timing of …

What is the pathophysiology of NSTEMI?

Pathophysiology. NSTE-ACS is most commonly caused by disruption of a coronary artery atherosclerotic plaque, with myocardial ischemia and injury often resulting from partial or intermittent occlusion along the ischemic cascade. Other causes beyond the focus of this work include embolism and revascularization.

What is multivessel coronary atherosclerosis?

Multi-vessel coronary artery disease (CAD) is a disease stage in which at least two or three of the epicardial coronary arteries is involved with atherosclerosis of significant severity. Multivessel disease is often associated with a higher burden of comorbidities, left ventricular dysfunction, and cardiovascular risk.

What is multivessel disease?

Multivessel coronary artery disease (MVD) is defined as luminal stenosis of at least 70% in at least two major coronary arteries or in one coronary artery in addition to a 50% or greater stenosis of the left main trunk.

How is multivessel disease treated?

Coronary artery bypass surgery (CABG) and percutaneous coronary intervention (PCI) are equally safe, and both are established treatment modalities of revascularization in patients with multivessel CAD.

Do you stent NSTEMI?

For NSTEMI patients, coronary stenting has a more modest benefit on both survival and symptoms—effects that are most notable in high-risk patients.

What is difference between PTCA and PCI?

Percutaneous transluminal coronary angioplasty (PTCA) also called percutaneous coronary intervention (PCI) is a minimally invasive procedure to open blocked or stenosed coronary arteries allowing unobstructed blood flow to the myocardium.

What happens to the heart during NSTEMI?

STEMI heart attacks are diagnosed when part of the wave, the ST segment, rises higher than normal. In most cases, a STEMI heart attack happens because of a total blockage of one of the main coronary arteries that provide blood flow to your heart muscle.

What is the pathophysiology of ACS?

The underlying pathophysiology in ACS is decreased blood flow to part of heart musculature which is usually secondary to plaque rupture and formation of thrombus. Sometimes ACS can be secondary to vasospasm with or without underlying atherosclerosis.

What is multivessel coronary artery stenosis?

Multivessel coronary artery disease (MVCAD) is defined by the presence of ≥50 % diameter stenosis of two or more epicardial coronary arteries. The presence of MVCAD indicates poorer prognosis and a significantly higher mortality than single-vessel disease.

What is 2 vessel coronary artery disease?

Definitions. 2VD + pLAD was defined as 70% or greater diameter stenosis of the pLAD and 50% or greater stenosis of either the left circumflex artery or the right coronary artery, determined visually by the cardiologist who performed the index diagnostic catheterization procedure between January 1997 and May 1999.
