Optimal combination secondary prevention drug treatment and stroke outcomes.

ABSTRACT:

Objective

To investigate the effect of optimal combination of evidence-based drug therapies including antihypertensive agents, lipid modifiers, and antithrombotic agents on risk of recurrent vascular events after stroke.

Methods

We analyzed the database of a multicenter trial involving 3,680 recent noncardioembolic stroke patients aged 35 years or older and followed for 2 years. Patients were categorized by appropriateness level 0 to III depending on the number of drugs prescribed divided by the number of drugs potentially indicated for each patient (0 = none of the indicated medications prescribed and III = all indicated medications prescribed). Independent associations of medication appropriateness level with recurrent stroke (primary outcome), stroke/coronary heart disease/vascular death as major vascular events (secondary outcome), and death (tertiary outcome) were assessed.

Results

The unadjusted rate of stroke declined with increasing medication appropriateness level (15.9% for level 0, 10.3% for level I, 8.6% for level II, and 7.3% for level III). Compared with level 0: the adjusted hazard ratio of stroke for level I was 0.51 (95% confidence interval, 0.21-1.25), level II 0.50 (0.23-1.09), and level III 0.39 (0.18-0.84); of stroke/coronary heart disease/vascular death for level I 0.60 (0.32-1.14), level II 0.45 (0.25-0.80), and level III 0.39 (0.22-0.69); and of death for level I 0.89 (0.30-2.64), level II 0.71 (0.26-1.93), and level III 0.35 (0.13-0.96).

Conclusions

Optimal combination of secondary prevention medication classes after a recent noncardioembolic stroke is associated with a significantly lower risk of stroke, major vascular events, and death.

Project description:BackgroundLack of compliance to medication and uncontrolled risk factors are associated with increased risk of recurrent stroke and acute coronary syndrome in patients with recent stroke. Multimodal patient education may be a strategy to improve the compliance to medication and early adoption of nonpharmacological measures to reduce the vascular risk factor burden in patients with stroke. We thus aim to develop multilingual short messaging services (SMS), print, and audio-visual secondary stroke prevention patient education package. The efficacy of the package will be tested in a randomized control trial to prevent major cardiovascular and cerebrovascular events.MethodsIn the formative stage, intervention materials (SMS, video, and workbook) were developed. In the acceptability stage, the package was independently assessed and modified by the stakeholders involved in the stroke patient care and local language experts. The modified stroke prevention package was tested for implementation issues (implementation stage).ResultsSixty-nine SMS, six videos, and workbook with 11 chapters with 15 activities were developed in English language with a mean ± SD SMOG index of 9.1 ± 0.4. A total of 355 stakeholders including patients (24.8%), caregivers (24.8%), doctors (10.4%), nurses (14.1%), local language experts (2.8%), physiotherapists (13.2%), and research coordinators (9.8%) participated in 10 acceptability stage meetings. The mean Patient Education Material Assessment Tool understandability score in all languages for SMS, video scripts, and workbook was 95.2 ± 2.6%, 95.2 ± 4.4%, and 95.3 ± 3.6%, respectively. The patients [n = 20, mean age of 70.3 ± 10.6 years and median interquartile range (IQR) baseline NIHSS 1 (0-3)] or the research coordinators (n = 2) noted no implementation issues at the end of 1 month.ConclusionAn implementable complex multilingual patient education material could be developed in a stepwise manner. The efficacy of the package to prevent major adverse cardiovascular events is being tested in the SPRINT INDIA study.
