Treatment Options

There are four main approaches to treating Coronary Artery Disease (CAD):

  • Lifestyle modifications
  • Medication
  • Minimally invasive surgical procedures
  • Bypass surgery


Early detection and treatment are important to control the disease and allow you a full selection of treatment options.

Your health care provider will determine the best treatment option for you based on your medical history and the severity of your condition.

Lifestyle Modifications

CAD treatment often includes making long-lasting lifestyle modifications. If you have CAD or want to lower your risk, your health care provider may prescribe one or more of the following:

  • Quit smoking. Don’t smoke, and if you do, quit. Consult with your health care provider to develop an effective cessation plan.
  • Lower your numbers. Work with your health care provider to correct any high blood pressure, cholesterol, and blood glucose levels.
  • Follow a healthy eating plan. Choose foods that are low in saturated fat, trans fat, and cholesterol. Be sure to include whole grains, vegetables, and fruits.
  • Get moving. Make a commitment to be more physically active. Aim for 30 minutes of moderate-intensity activity on most, preferably all, days of the week.
  • Aim for a healthy weight. If you are overweight or obese, work with your health care provider to develop a supervised weight loss plan.
  • Manage diabetes. Lower blood glucose levels to reach an A1C of less than seven.

According to the American Heart Association, 16.3 million people in the United States have been diagnosed with CAD, the most common form of heart disease. CAD is common in patients with diabetes1,2, kidney disease3 and smokers.4


In addition to lifestyle modifications, your health care provider may prescribe one or more medications. Medications are used to:

  • Lower high blood pressure and cholesterol levels and treat diabetes
  • Prevent the formation of blood clots that could cause a heart attack or stroke
  • Lower cholesterol and manage angina symptoms


For people suffering from Coronary Arterial Disease (CAD), a build-up of plaque in the vessels of your heart causes a narrowing in the opening and reduces the amount of blood that can flow to your heart. Over time, this plaque can become severely calcified—or hardened—with limited options to successfully treat the problem – until now.

CSI’s Orbital Atherectomy System

The good news is that a procedure called “orbital atherectomy” [ath-uh-rek-tuh-mee] can help reduce the hard plaque in your vessels and increase blood flow to your heart.

The Diamondback 360® Coronary Orbital Atherectomy System is the only device that is FDA approved to treat severe calcium and has been used on more than 5,000 patients. It is backed by clinical evidence that demonstrated that it is an effective treatment to facilitate stent delivery.

The Orbital Atherectomy System uses simple physics to treat complex CAD with severe calcium. It applies the basic principles of centrifugal force to orbit around the vessel wall. As it moves, its diamond-coated crown sands calcium deposits into tiny microparticles (smaller than the size of a red blood cell) that the bloodstream can naturally flush away – restoring blood flow.

Though the Orbital Atherectomy System has a substantiated safety profile in treating coronary lesions, results may vary. Also, not all patients may be eligible for orbital atherectomy treatment based on their unique health considerations.

If you’ve already been diagnosed with CAD, you may want to ask your doctor if orbital atherectomy is a treatment option for you.

Balloon Angioplasty

Balloon angioplasty is a procedure where a balloon is inflated and plaque is pushed against the arterial walls, causing the artery to widen and restoring blood flow.

When Orbital Atherectomy is used prior to stent placement in severely calcified lesions, it is associated with long term durable outcomes.


A stent (tiny metal cylinder) is often placed in the artery after the angioplasty procedure with the intent to keep the diseased artery open.

Bypass Surgery

Surgery may be necessary if blood flow through multiple arteries is completely or almost completely blocked. In bypass surgery, a blood vessel from another part of the body or a tube made of synthetic material is used to bypass the blockage in the artery. This allows blood to flow around the blockage and back into the artery.

Bypass surgery is major surgery. Some patients, due to other risk factors, may not be good surgical candidates.
