Factors Related to Nonachievement of Intensive Blood Pressure-Lowering Target in Patients with Intracerebral Hemorrhage.

BACKGROUND

Spontaneous intracerebral hemorrhage (ICH) is one of the most disabling forms of stroke. Intensive lowering of blood pressure (BP) has been postulated as one of the therapies that can improve functional outcomes. However, this intensive reduction is not always achieved. We aimed to study the differences between patients in whom intensive BP lowering was achieved during the first 24 h after admission and those in whom this BP lowering was not possible.

METHODS

We retrospectively reviewed medical charts to obtain information on BP management during the first 24 h. Our protocol establishes that intensive BP lowering below 140 mm Hg of systolic BP should be pursued.

RESULTS

In total, 210 patients were included. In 107 (51.0%), an intensive target BP was not achieved. This group of patients had higher initial National Institutes of Health Stroke Scale scores and poorer clinical evolution, with more early neurological deterioration, higher requirements for antihypertensive treatment, higher necessity for surgical evacuation, more withdrawal of life-sustaining therapies, and higher mortality at 3 months (all p < 0.05). In the multivariable analysis, high BP levels at admission remained related to the nonachievement of BP-lowering goals, despite a higher administration of antihypertensive medications.

CONCLUSIONS

In this study, the intensive BP-lowering goal was not achieved in about half of the patients with ICH, despite the high proportion of patients receiving antihypertensive medications. This group of patients had poorer outcomes and higher mortality rates at 3 months. High BP at presentation may be difficult to control in patients with high clinical severity of ICH despite aggressive management.
