Long-term results of endovascular treatment of ischemic heart disease in hypertensive patients

Aim. To ascertain long-term prognosis after endovascular treatment of ischemic heart disease (IHD) in patients with arterial hypertension (AH). Material and methods. The trial enrolled 87 IHD patients (mean age 54 +/- 8 years) who have undergone successful transluminal ballon coronary angioplasty (TBCA) or stenting. The patients were divided into two groups. Group I consisted of IHD patients with mild or moderate AH, group 2 - of IHD patients without A H. The repeat examination was made 1-72 months (34 +/- 12) after TBCA, control coronarography was performed in 42 (48%) patients. Results. The groups did not differ much by clinical and angiographic characteristics. Within 72 months the number of unfavourable clinical outcomes (UCO) in group I was significantly higher (68 and 19516, respectively; p = 0.02) as well as frequency of repeated TBCA (43 and 19%, respectively, p = 0.03). In both groups TBCA were repeated more frequently because of restenosis than of fresh lesions (91 and 33%, p < 0.0001; 70 and 20916, p = 0.04, respectively). The probability of no need in repeated TBCA was significantly less in group 1 than group 2 (41 and 72%, respectively; p = 0.007), the probability regressing more actively within 8 months after the intervention. Conclusion. Total incidence of UCO seventy two months after the endovascular treatment was higher in AH patients primarily due to repeated TBCA. Most of TBCAs were conducted within 8 months after the intervention for restenosis.
