Background: There are some reports that blood pressure was significantly decreased after endovascular treatment (EVT) for renal artery stenosis (RAS), but whether the decrease in blood pressure improve the prognosis or not still remains unknown.
Methods: There were 364patients who underwent EVT for RAS in Kokura memorial hospital from 1996 to 2015. Among them we selected and analyzed 217 patients we could check their blood pressure within 12months after EVT for RAS retrospectively to investigate the impact of decrease in blood pressure after EVT for RAS.
Results: The mean follow-up was 5.97±3.2 years. The mean change of Blood pressure within 12 months after EVT was -9.1±2.3mmHg. At 6 years in the patients group whose blood pressure had dropped more than 15mmHg, compared to the other group, overall survival and freedom from MACE (Major Adverse Cardiovascular Events) were significantly higher (64.7% vs 30.1% P<0.001;39.5% vs 31.5%,P<0.001). On multivariate analysis, medication of ACE-I/ARB (hazard ratio [HR] 1.43, 95% 1.05 to 1.95 P=0.023), multiple medicines for hypertension (more than 2) (hazard ratio [HR] 1.45, 95% 1.05 to 1.98 P=0.031) and chronic kidney disease (eGFR <50) (hazard ratio [HR] 0.63, 95% 0.40 to 0.98 P=0.023) were the independent predictors of decrease in blood pressure more than 15mmHg.
Conclusions: The prognosis of the patient whose blood pressure had dropped more than 15mmHg after EVT for RAS was better than the patient who was not in the case.
