Blood pressure levels in the acute phase after intracerebral hemorrhage are associated with mortality in young adults.

Abstract：

BACKGROUND AND PURPOSE:Blood pressure (BP) levels in acute intracerebral hemorrhage (ICH) and mortality have not been thoroughly studied in the young. METHODS:The relationship between BP and mortality was assessed in consecutive patients with first-ever, non-traumatic acute ICH at ≤50 years of age, enrolled in the Helsinki ICH Young Study. BP parameters included systolic BP (SBP), diastolic BP (DBP), mean arterial pressure and pulse pressure (SBP - DBP) at admission and 24 h, and delta (admission-24 h) BP parameters. Outcome measures were 3-month and long-term mortalities, adjusted for demographics and ICH score parameters for short-term and cardiovascular risk factors for long-term prognostics. Cox regression models were used to assess independent BP parameters associated with mortality. RESULTS:Of our 334 patients (61% male), 92 (27%) had pre-stroke hypertension and 54 (16%) used antihypertensive treatment. The follow-up extended to 17 years with a median of 12 (interquartile range, 9.65-14.7) years. Both 3-month (n = 56; 16%) and long-term (n = 97; 29%) mortalities were associated with significantly higher admission SBP and mean arterial pressure levels, but not with 24-h BP levels, compared with survivors. Patients with SBP ≥ 160 mmHg (n = 156; 46%) had a significantly higher mortality rate (n = 59, 17% vs. n = 38, 11%; P = 0.001) and died earlier (9.6; 95% confidence interval, 2.9-12.9 years vs. 11.3; 95% confidence interval, 8.1-13.9 years; P = 0.001) within the follow-up period. In multivariable analyses, admission SBP ≥160 mmHg was independently associated with both 3-month (hazard ratio, 2.50; 95% confidence interval, 1.19-5.24; P < 0.05) and long-term (hazard ratio, 2.02; 95% confidence interval, 1.18-3.43; P < 0.01) mortalities. CONCLUSIONS:In young patients with ICH, acute-phase SBP levels ≥160 mmHg are independently associated with increased mortality.
