Investigation Myocardial Perfusion Scan Parameters and Walls Motion in Patients undergoing Cardiac Surgery

Area of Science:

• Cardiology
• Diagnostic Imaging
• Nuclear Medicine

Background:

• Coronary heart disease, a leading cause of cardiovascular disease, stems from arterial blood flow blockages.
• Myocardial Perfusion Scan (MPS) offers a non-invasive assessment of cardiac function.
• Key MPS parameters include End Diastolic Volume (EDV), End Systolic Volume (ESV), Ejection Fraction (EF), Lung to Heart Ratio (LHR), and Transient Ischemic Dilatation (TID).

Purpose of the Study:

• To investigate how gated heart scan parameters change in patients considered for heart surgery.
• To establish the diagnostic utility of these parameters in surgical candidates.

Main Methods:

• A descriptive cross-sectional study involving 40 heart surgery candidates.
• Evaluation of gated heart scan parameters: TID, ESV, LHR, and EF.
• Analysis of cardiac output and heart wall motion.

Main Results:

• One-sample t-test revealed statistically significant differences in parameters (P<0.0001).
• All analyzed parameters were within the normal range.
• Observed changes in cardiac output and heart wall motion in all patients.

Conclusions:

• Myocardial Perfusion Scan (MPS) parameters are valuable for diagnosing patients requiring heart surgery.
• Gated heart scan analysis provides an effective diagnostic method for pre-surgical cardiac assessment.
