This study followed patients presenting to the ED with elevated (SBP>180, DBP>120) blood pressure without evidence of end organ dysfunction for one year. The patients were followed for major adverse cardiac events. They found:
“A total of 12,044 patients were enrolled. The prevalence of MACE within one year was 1,865 (15.5%). Older age, male gender, history of cardiovascular disease, cerebrovascular disease, diabetes, smoking, presentation with chest pain, altered mental status, dyspnea, treatment with intravenous and oral hydralazine, and oral metoprolol were independent predictors for one-year MACE. Additionally, discharge with an SBP ?160 mm Hg was not associated with 30-day MACE-free survival after propensity matching (hazard ratio 0.99, 95% confidence interval 0.78–1.25, P?=?0.92).”
Treating to reach a magic number did not help. Most likely, long term control of blood pressure is a more important factor than attempts to lower in the ED. While this is a high risk group, there is no evidence that acute lowering of blood pressure impacts long term survival.
