Insights
Antihypertensive medication use in acute ischemic stroke (AIS) patients impacts blood pressure variability and is linked to reduced mortality. Personalized management based on prior medication history may improve outcomes for AIS patients.
Area of Science:
- Neurology
- Cardiology
- Pharmacology
Background:
- Blood pressure management in acute ischemic stroke (AIS) is complex.
- The role of antihypertensive medications (AHT) before and during stroke is not fully understood.
Purpose of the Study:
- To investigate the impact of pre- and intra-stroke AHT use on blood pressure (BP) parameters and variability.
- To assess the association between AHT use and 3-month mortality in AIS patients.
Main Methods:
- Post-hoc analysis of 228 AIS patients from the PREVISE study.
- 24-hour ambulatory BP monitoring within 48 hours of symptom onset.
- Analysis of clinical data, AHT details, and 3-month mortality.
Main Results:
- Most AIS patients (84.2%) were on AHTs prior to stroke.
- Specific AHTs were associated with altered BP variability and daytime BP levels.
- AHT use during AIS was linked to reduced mortality, with certain AHT classes showing better outcomes.
Conclusions:
- Personalized BP management in AIS, considering antihypertensive history, is recommended.
- These findings can guide treatment efficacy, future research, and patient care in AIS.
Objectives:
The management of blood pressure (BP) and the role of antihypertensive medications (AHT) in acute ischemic stroke (AIS) remain uncertain. This study aimed to investigate the impact of pre- and intra-stroke AHT use on systolic (SBP), diastolic (DBP), and blood pressure variability (BPV).
Materials And Methods:
A post-hoc analysis was conducted on 228 AIS patients from the PREVISE study. All patients underwent 24-hour ambulatory blood pressure monitoring within 48 h of symptom onset. Clinical and laboratory data, as well as AHT details, were recorded. Mean BP parameters and BPV for SBP and DBP were computed. The study endpoint was 3-month mortality.
Results:
The majority of stroke patients (84.2%) were already taking AHTs. Beta blockers and ACE inhibitors use before and after stroke were linked to higher DBP variability. Prior angiotensin receptor blockers (ARBs) and vasodilators use correlated with increased SBP variability and lower daytime SBP/DBP levels, respectively. The continuation, discontinuation, or change of AHTs after stroke onset did not significantly affect outcomes. Patients under AHTs during AIS exhibited reduced mortality, with those previously using calcium channel blockers experiencing less severe strokes, and those previously using ARBs showing better outcomes at three months.
Conclusions:
These findings advocate for personalized BP management in AIS, based on a patient's antihypertensive history. These insights could enhance treatment efficacy, guide research, and improve care for acute ischemic stroke patients.
