3.   Cannon said he expected that in six months, patients with ST elevation heart attacks will be taken only to the hospitals that perform angioplasty.

4.   Four months later, doctors performed an angioplasty on Cheney, and he has been under close medical supervision ever since.

5.   His cardiologist at Baptist Medical Center, Dr. William C.L. Wu, performed another angioplasty and implanted a new stent.

6.   Some hospitals can only inject clot-dissolving drugs while others can perform angioplasty.

7.   Such facilities are generally required by state regulation or community standards before a hospital can perform angioplasty.

8.   The doctors performed an angioplasty, a procedure that opens the artery, and implanted a stent, a mesh tube that keeps the blood vessel open.

9.   The researchers want assurance that all seven hospitals that perform angioplasties do so around-the-clock every day so that all patients will get angioplasties and not TPA.

10.   Then, the angioplasty might be performed again, a stent may be added, or bypass surgery might be done, depending on the progress of the disease.
