| Abstract: | AIM: To characterize coronary arteries and myocardial perfusion in isolated ischemic heart disease (IHD) and IHD combined with blood hypertension (BH). MATERIALS AND METHODS: 20 patients with isolated IHD and 25 patients with combined IHD have undergone coronarography, scintigraphy of the myocardium with Tc-99m, echocardiography. RESULTS: In the combined IHD, overall involvement of the heart arteries appeared less than in isolated IHD (33.40 +/- 7.07% versus 41.40 +/- 8.9%). In the combined IHD and left ventricular hypertrophy (LVH) overall involvement of the heart arteries was less while occurrence of perfusion disorders higher than in the absence of LVH (35.98 +/- 4.73% vs 47.21 +/- 5.91%, and 33.7 vs 25.0%, respectively). Defects in the myocardial perfusion both in right and left coronary artery, isolated and combined IHD were of the same type location. CONCLUSION: Disturbed myocardial perfusion is an essential factor in the onset of coronary insufficiency. |
