Brief Summary:
The primary objective is to evaluate if use of the AngioGuard™ XP improves myocardial reperfusion after PTCA as assessed by ST segment resolution at the end of PTCA.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Device: Angioguard distal protection device Other: PTCA Phase 2

Detailed Description:
This is a prospective, randomized, multicenter trial. Patients will be randomized either to be treated by PTCA only or in combination with the An-gioGuard™ XP device. The patients will be followed for six-months post-procedure.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 56 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single
Primary Purpose: Treatment
Official Title: Distal Protection Combined With PTCA in AMI Patients -- The DIPLOMAT Study.
Study Start Date : March 2002
Actual Study Completion Date : August 2004

Arm Intervention/treatment
Other: PTCA
PTCA with angioguard
Device: Angioguard distal protection device
PTCA with the Angioguard distal protection device.
Other Name: Cordis AngioGuard™ XP

Primary Outcome Measures :
  1. Absolute ST segment resolution. [ Time Frame: post-PTCA ]

Secondary Outcome Measures :
  1. ST segment resolution (> 50% decrease). [ Time Frame: pre- and post-PTCA ]
  2. TIMI Frame Count [ Time Frame: post PTCA ]
  3. Composite endpoint of slow flow, no reflow or distal embolization. [ Time Frame: at anytime ]
  4. Regional wall motion index by echocardiography. [ Time Frame: discharge and 6 month follow-up ]
  5. Clinical success evaluation; qualitative evaluation of device and delivery system characteristics. [ Time Frame: post-procedure ]
  6. Cardiac function assessed by echocardiography. [ Time Frame: before discharge and at 6 month follow-up ]
