[Proignostic Factors of Cardiovascular Complications After Ischemic Stroke]

Area of Science:

• Neurology
• Cardiology
• Epidemiology

Background:

• Ischemic stroke survivors face a high risk of subsequent cardiovascular events (CVE).
• Identifying predictors of CVE is crucial for secondary prevention strategies.
• Previous studies have explored various risk factors, but comprehensive analysis in this cohort is needed.

Purpose of the Study:

• To identify independent predictors of cardiovascular events (CVE) in patients following an ischemic stroke.
• To analyze the association between baseline characteristics, comorbidities, and antihypertensive therapy with CVE occurrence.
• To inform secondary prevention guidelines for ischemic stroke patients.

Main Methods:

• Prospective cohort observational study including 148 ischemic stroke patients (aged 60 [52; 68] years).
• Follow-up duration of 35 [28; 40] months, registering recurrent stroke, transient ischemic attack, myocardial infarction, unstable angina, heart failure, and cardiovascular death.
• Multivariate regression analysis was employed to determine independent predictors of CVE.

Main Results:

• During follow-up, 37 patients (25%) experienced 50 CVE.
• Independent predictors of CVE included age over 67 years, chronic ischemic heart disease, and high-grade ventricular arrhythmias.
• Low standard deviation of cardiointervals (SDNN) (< 71 ms) and absence of thiazide diuretics in antihypertensive therapy were also significant predictors.

Conclusions:

• Age, chronic ischemic heart disease, ventricular arrhythmias, low SDNN, and lack of thiazide diuretic use are significant independent predictors of CVE after ischemic stroke.
• These findings highlight the importance of comprehensive risk assessment and tailored antihypertensive strategies in stroke survivors.
• Further research should focus on the mechanisms underlying these associations and the efficacy of interventions targeting these predictors.
