PRESENTATION OVERVIEW Brief review of intracranial hemorrhaging (ICH) Review of current AHA/ASA guidelines Qureshi A, Palesch Y, Barsan W, Hanley D, Hsu C, Martin R et al. article
Conclusions Questions
INTRACRANIAL HEMORRHAGE Definition Type of bleeding that occurs within the skull
Incidence Crude incidence is approximately 15.9 per 100000
Mortality rates 34.6% at 7 days 50.3% at 30 days 59% at 1 year Diabetes mellitus and posterior fossa hemorrhage had higher mortality rates
GUIDELINES FOR THE MANAGEMENT OF SPONTANEOUS
INTRACEREBRAL HEMORRHAGEHemphill J, Greenberg S, Anderson C, Becker K, Bendok B, Cushman M et al.
CURRENT BLOOD PRESSURE LOWERING GUIDELINES Elevated BP in ICH Very common symptom of acute ICH Generally due to stress, pain, increase intracranial pressure (ICP) and premorbid acute or persistent high BP
High systolic blood pressure (SBP) generally associated with greater neurological detriment, death, hematoma expansion and dependency post ICH
Current Guidelines ICH patients with SBP between 150 and 220 mmHg
Reduce to SBP to 140 mmHg ICH patients with SBP >220 mmHg
Aggressive reduction with IV infusion and frequent monitoring
CURRENT STANDARD OF CARE Nicardipine Used to lower patients to <160 mmHg Current standard of care Based on ATACH (Antihypertensive Treatment of Acute Cerebral Hemorrhage) trial
BP Lowering Presenting with SBP 150-220 mmHg without contraindication
Treat to a SBP 140 mmHg Presenting with SBP >220 mmHg
Reasonable for aggressive BP reduction Continuous IV infusion and frequent BP monitoring
INTENSIVE BLOOD-PRESSURE LOWERING IN PATIENTS WITH
ACUTE CEREBRAL HEMORRHAGEQureshi A, Palesch Y, Barsan W, Hanley D, Hsu C, Martin R et al
DESIGN Trial Randomized Multicenter Two-group Open-label
Population (n=1000) Within 4.5 hours of symptom onset >18 years old Glasglow Coma Scale (GCS) >5 Intraparencymal heatoma <60 cm3
Qureshi A et al. Intensive Blood-Pressure Lowering in Patients with Acute Cerebral Hemorrhage. NEJM
MEASURES Primary Outcomes Proportion of patients having moderately severe-severe disability
Modified Rankin scale score, 4-6 Proportion of patients having died
Secondary Outcomes EQ-5D score Visual-analogue scale (VAS) at 3 months Proportion of patients with a >33% volume increase in hematoma size
Statistical Analysis Proportion of risk

OUTCOMES
OUTCOMES Primary Outcomes No difference between intensive and standard treatment
Secondary Outcomes No difference between treatment groups
Other Outcomes No differences between groups in rate of death at 3 months post randomization No difference between groups in neurological deterioration at 24 hours post randomization
Qureshi A et al. Intensive Blood-Pressure Lowering in Patients with Acute Cerebral Hemorrhage. NEJM
ADVERSE EVENTS 72 hours after randomization 1.6% of the intensive treatment group 1.2% of the standard treatment group No significant difference
3 months after randomization 25.6% of the intensive treatment group 20.0% of the standard treatment group No significant difference
Renal Adverse events Significantly higher in the intensive treatment group than standard treatment group
Only significant difference across adverse-event groupsQureshi A et al. Intensive Blood-Pressure Lowering in Patients with Acute Cerebral Hemorrhage. NEJM
CONCLUSIONS Trial Observations Rate of death or disability at 3 months was much lower than expected based on current literature 37.7% in trial 60% in literature
Trial Conclusions No overall differences between groups Acute reduction to a target systolic blood pressure of 110-139 mmHg not supported
Significant renal adverse events within 7 days of randomization for intensive treatment group
No support for the idea that lowering blood pressure to the above stated range improves functional outcomes for patients with ICHQureshi A et al. Intensive Blood-Pressure Lowering in Patients with Acute Cerebral Hemorrhage. NEJM
