Abstract

OBJECTIVES To evaluate the incidence and prognostic power of arterial hypertension in patients with coronary artery disease treated with surgical myocardial revascularisation, before and after the operation. BACKGROUND Arterial hypertension is one of the leading modifiable risk factors in CAD patients who underwent CABG surgery with the major impact on clinical outcome in these patients. METHODS 749 patients with mean age of 55 +/- 8 years, (639 male/119 female) were analyzed for their preoperative: demographic, clinical, left ventricular morphologic and functional and angiographic, perioperative: type of operation, type and number of applied conduits, in-hospital morbidity and mortality, and post-operative: demographic, clinical, left ventricular morphologic and functional and angiographic characteristics. Mean postoperative follow-up period was 5.97 +/- 4.27 years. RESULTS Hypertension was found in 52.7% of patients before the operation, and it was the most frequent risk factor, without any differences between different age groups, but significantly more often in females (p = 0.0001), diabetics (p = 0.0001), and patients with preserved LV function (p = 0.011). Although significantly correlated with in-hospital morbidity (r = 0.085 and p = 0.023), HTA was not identified as independent predictor. The most predictable was the occurrence of early neurological complications. HTA was also found to be a predictor of long life prognosis in CABG patients, but not as independent prognostic factor. Significant reduction in incidence was found in post-CABG patients (30.1%), which is most likely a result of applied pharmacologic treatment. ACE-inhibitors, Ca-antagonists and B-blockers were applied in 39.44%, 30.1% and 33.6% of patients respectively, with significant positive correlations found for all of them as follows: r = 0.221, p = 0.0001, r = 0.316, p = 000.1 and r = 0.093, p = 0.031. CONCLUSION Hypertension is the most powerful risk factor in CAD patients who undergo CABG surgery in our country, and a powerful prognostic factor of early and late clinical outcome. There is a trend toward decreasing the incidence of HTA in post-CABG patients, as a result of improved pharmacologic treatment after the operation (Tab. 5, Fig. 1, Ref. 13).
