Abstract :
Objectives: Myocardial perfusion scintigraphy (MPS) is widely used in functional assessment of myocardial perfusion. But, some study results are in contradiction with severity of coronary artery disease detected by coronary angiography (CA). It is frequently encountered case that CA is completely normal whereas MPS describes ischemia. In this study, we aimed to investigate whether mild atherosclerotic lesions cause ischemia. Materials and methods: MPS with 99mTc-MIBI was performed in 52 patients who applied to cardiology clinics for history of chest pain and underwent diagnostic CA within 3 months. Results: In 22 of 52 patients with mild atherosclerotic lesions, ischemia in various degrees was detected on MPS. In statistical analysis, any signifi cant relationship was not found between ischemia and gender, hypertension, DM, dyslipidemia, smoking, mitral valve insuffi ciency, left ventricular hypertrophy, exercise testing result and affected coronary artery. Conclusion: Our study fi ndings have shown that mild atherosclerotic lesions even at very early stage may cause myocardial ischemia
