OBJECTIVES: Pulmonary hypertension (PH) is closely related to clinical decompensation and poor clinical outcomes in atrial fibrillation (AF) patients. However, the association between PH and ischemic cerebrovascular events (ICE) in AF patients has not been investigated. The authors purposed to examine this relationship.
MATERIALS AND METHODS: The researchers conducted an observational study on 371 AF patients between January and November 2021. In line with the European Society of Cardiology guideline recommendations, echocardiographic parameters suggestive of PH were performed. The study population was stratified into two groups based on the presence (n = 98, 31%) or non-presence (n = 219, 69%) of PH. Also, we did logistic regression analyses for the independent predictors of the ICEs in AF patients.
RESULTS: Ischemic cerebrovascular events were significantly more frequent in the PH group than the non-PH group (n = 30, 13% vs. n = 18, 18%, p = 0.03). At univariable analysis, hypertension, diabetes mellitus, PH (OR = 0.23 [95% CI, 0.13-0.41], p = 0.005) and diastolic dysfunction were significantly related to ICE in AF patients. Moreover, at multivariable analysis, age, diabetes mellitus, PH (OR = 0.19 [95% CI, 0.10-0.36], p = 0.01), and diastolic dysfunction were predictive of ICE.
CONCLUSIONS: Pulmonary hypertension is likely associated with ischemic cerebrovascular events in patients with AF, requiring further investigation to determine its association.
