And even less blood will actually reach the heart muscle because of the narrowed coronary arteries.

He said the man smoked and had high cholesterol and narrowed coronary arteries.

Atherectomy is a procedure used to open up narrowed coronary arteries to increase blood flow.

In the late 1970s, doctors began using balloon angioplasty to treat narrowed coronary arteries.

For example, the scans identify narrowed coronary arteries in people with no symptoms of heart disease, like chest pains.

A heart attack occurs when a clot or spasm blocks an already narrowed coronary artery.

Atherosclerosis usually has no symptoms until the narrowed coronary arteries severely restrict blood flow to the heart.

Eventually, a narrowed coronary artery may develop new blood vessels that go around the blockage to get blood to the heart.

A balloon catheter, placed over a guide wire, is used to insert the stent into the narrowed coronary artery.

Anti-clotting drugs will probably first be used to maintain blood flow in patients with severely narrowed coronary arteries who are awaiting open-heart surgery.

Evidence of severely reduced blood flow (ischemia) to an area of heart muscle caused by one narrowed coronary artery.

Stable angina pectoris: Narrowed coronary arteries cause predictable chest pain or discomfort with exertion.

This happens as a result of the narrowed coronary arteries being always maximally dilated to compensate for the decreased upstream blood supply.

The major causes include damage from heart attacks, blocked or narrowed coronary arteries, diseased heart valves, high blood pressure and diabetes.

But they are not believed to be in immediate danger of heart attacks or hospitalization, even though accumulating plaque has narrowed coronary arteries 70 percent or more.

Percutaneous coronary intervention (PCI) is similar to cardiac catheterization but it is used to open up a narrowed coronary artery.

Usually made of metal mesh, heart stents are implanted in narrowed coronary arteries during a procedure called a percutaneous coronary intervention (PCI) or angioplasty.

A catheter, or small tube, with a deflated balloon at its tip is inserted into the femoral artery in a thigh and passed up to the narrowed coronary artery.

FFR has certain advantages over other techniques to evaluate narrowed coronary arteries, such as coronary angiography, intravascular ultrasound or CT coronarography.

With PCI, your doctor guides a thin flexible tube (catheter) into the narrowed coronary arteries to open them using special tools and to improve blood flow to your heart.

Buoyed by this evidence, many researchers now think that tiny blood clots that clog the heart's arteries are a prime culprit in heart attacks, which previously were attributed solely to narrowed coronary arteries.

The Institutes are competent to handle sny kind of cardiology cases like Acute MI, temporary and permanent pacemakers, narrowed coronary arteries, angina, valvular heart diseases and heart failure.

Dr. Nissenson and colleagues pointed out that advanced age and narrowed coronary arteries might render the hearts of the elderly less able to compensate for the effects of anemia in the event of a heart attack.

But experts say common drugs that can relieve angina are often ignored in favor of more aggressive approaches like bypass surgery or stenting, the insertion of wire mesh tubes that prop open narrowed coronary arteries.

Angioplasty, also know as percutaneous coronary intervention (PCI) or percutaneous transluminal coronary angioplasty (PTCA), is a procedure in which a catheter-guided balloon is used to open a narrowed coronary artery.
