Myocardial perfusion Imaging

[Aqeel11]

Hello!
My MIBI Pharmacological Myorcardial Perfusion imaging report with procedure and findings are as under.
Can you help me understand the test results and findings with further advice!

Procedure: Pharmacological stress Tc-99m MIBI scan was performed with Dipyridamole given at arate of 0.14 mg/Kg/min over 4 minutes followed by injection of radio tracer 6 minutes later.

Findings are: Peak stress images revealed hypoperfused infero-septal and apical segment, which showed reversal at rest.

Impression: Findings are consistent with infero-septal and apical reversible ischemia.

Thanks all!

Hello!
Thanks for the reply!

Further, I recently had an angiography, the report is as...


LMS: Normal
LAD: 55-60 % stenosis in mid LAD,
D1 has mild disease in ostium and tight disease in mid course

LCx: Plaques at ostium . Rest is normal.
Ramus: Subcritical disease in ostial Ramus
RCA: Good size, dominant vessel and normal

Can any one suggest me what that report is all about? What should be the Way forward!

Thanks

Hi, a nuclear stress test provides information regarding the coronary artery blood flow to the heart muscle. A "perfusion defect" is a way of saying that there is the appearance of reduced blood flow to a part of the heart muscle. When images return to normal at rest, this indicates there is no permanent injury to the heart muscle. Reversible perfusion defect is an area of the heart muscle that does not receive an adequate amount of blood at stress (ischemia) but does so at rest (reversible ischemia). Here the muscle can be saved and the areas identified are infero-septal and apical segment. After identifying the defects a cardiac catheterization helps to study the arterial structure of the heart and to identify the blocks for further therapy. So, your doctor may next ask for cardiac catheterization. Please follow up with him. Regards.
