[Coronary artery function and myocardial perfusion in patients with ischemic heart disease isolated and in combination with arterial hypertension].

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.
