We assessed the hypothesis that blood pressure (BP) lowering therapy may decrease the incidence of recurrent stroke in patients with hypertension in the long-term follow up after coronary artery bypass grafting (CABG).Design and method:
A total of 660 patients with history of stroke, who underwent CABG procedure in our centre, between October 2007 and November 2011, studied and divided into 4 groups based on mean office BP achieved: hypertension (HTN) group with poor BP control (n = 80), HTN group with moderate BP control (n = 246), HTN group with goal BP control (n = 218) and normotensive group (n = 116).Results:
The incidence of recurrent stroke during 36 months after CABG was significantly higher in HTN group with poor BP control (hazard ratio: 5.03, 97% confidence interval: 3.311–17.030, p < 0,001). The incidence of recurrent stroke depended on long-term level of BP control.Conclusions:
In the long-term follow up patients after CABG procedure, poor blood pressure control increased the risk of recurrent stroke in patients with hypertension.
