Relationship between DBP and the myo-cardial ischemia in myocardial perfusion scintigraphy (MPS) was investigated.Methods: Patients with chronic coronary artery disease who underwent MPS were included. One day stress/rest gated MPI with Tc-99m MIBI protocol was applied to all patients. Blood pressures was measured before MPI. Patients were divided into 2 groups as ?75 mmHg and >75 mmHg according to DBP. The SDS were calculated using the sum of the 17-segment.Results: The patients with DBP ?75 mmHG and with DBP>75 mmHG were compared, there was no significant differ-ence in SDS (4.44±4.67 and 4.65±4.70 respectively; p=0.657). Association of DBP ?75 mmHg with SDS appeared to be primarily among those with SBP >130 mmHg. Patients with DBP ?75mmHg and SBP >130mmHg had different SDS (6.87±6.00 and 4.99±4.77; p=0.015) between patients with DBP >75 mmHg and SBP >130mmHg. Conclusion: Coexistence lower diastolic blood pressures (?75mmHg) with higher systolic blood pressures (>130mmHg) could be a predictor of myocardial ischemia in patients who underwent adenosine stress MPI

Amaç:Kronik koroner hastalığı (KAH) olan hastalarda, düşük diyastolik kan basıncının (DKB) mortalite dahil olmak üzere olumsuz kardiyovasküler sonuçlarla ilişkilidir, ancak iskemi ile ilişkisi bilinmemektedir. Bu çalışmamızda düşük diyastolik kan basıncının (DKB) miyokard perfüzyon sintigrafinde (MPS) iskemi ile ilişkisi araştırıldı.Yöntemler:Tüm hastalara tek gün TI-99m MIBI protokolü uygulandı. Kan basınçları işlemden hemen önce ölçüldü. Hastalar DKB değerlerine göre ?75mmHg ve >75mmHg olarak iki gruba ayrıldı. 17 segment kullanılarak SDS (summed difference score) hesaplandı
