Is the Effect of Intensive Antihypertensive Treatment in Acute Intracerebral Hemorrhage Dependent on Hematoma Volume? A Traditional Meta-analysis of the Effect of Antihypertensive Regimens, a Bayesian Network Meta-analysis of the Mortality of Antihypertensive Drugs and Systematic Review
摘要
Intensive or conventional antihypertensive treatment for acute intracerebral hemorrhage is still controversial. This study aimed to compare those antihypertensive regimens and analyze the efficacy of antihypertensive drugs.
MethodsRetrieval was conducted through four databases. Meta-analysis and Bayesian network meta-analysis were performed to evaluate the safety of antihypertensive treatments and the efficacy of antihypertensive drugs.
ResultsA total of 9271 patients were included. Intensive strategy showed an advantage in 24-h hematoma enlargement (relative risk, RR = 0.76; 95% confidence intervals, CI = 0.67–0.87; P < 0.0001) and 90-day intracranial rebleeding (RR = 0.71, 95% CI = 0.52–0.96, P = 0.03) compared with conventional strategy. Meanwhile, the 90-day renal insufficiency (RR = 2.31, 95% CI = 1.05–5.05, P = 0.04) and renal failure (RR = 2.42, 95% CI = 1.20–4.86, P = 0.01) were increased. When cerebral hematoma volume was less than 15 ml, intensive strategy had a protective effect on 24-h hematoma enlargement (RR = 0.77, 95% CI = 0.67–0.89, P = 0.0003), but it increased 90-day renal failure (RR = 2.33, 95% CI = 1.07-5.04, P = 0.03). For the volume greater than 15 ml, it enhanced 90-day functional independence (RR = 0.78, 95% CI = 0.65–0.94, P = 0.01) and decreased intracranial rebleeding (RR = 0.68, 95% CI = 0.49–0.94, P = 0.02). Labetalol was the best, with the mortality risk probability of 0.09 and the surface under the cumulative ranking curve of 0.33.
ConclusionsThis meta-analysis suggests that for intracerebral hematoma volume greater than 15 ml, intensive antihypertensive treatment can improve functional independence and reduce intracranial bleeding. Labetalol has the best effect among the four antihypertensive regimens studied.
