Abstract
Introduction
We aimed to find new predictive parameters for atrial fibrillation (AF) onset in hypertensive patients using two-dimensional (2D) conventional and speckle tracking echocardiography of the left atrium (LA).
Methods
One hundred and eight patients with essential hypertension (HTN) were prospectively enrolled, from which 67 patients had no other important comorbidities (HTN group), while 41 patients had a recent AF episode, but were in sinus rhythm at the moment of enrollment (HTN and AF group). LA diameters and maximal volume, LV mass, LV ejection fraction and diastolic function were assessed through 2D conventional echocardiography. Moreover, peak longitudinal and contractile strain of LA walls (PALS and PACS, respectively) were analyzed by speckle tracking technique. Patients were followed up for 1 year and recurrent 24-h rhythm monitoring was done, in order to identify atrial fibrillation.
Results
Age and time from diagnosis of HTN were higher in HTN and AF group than in HTN group (68.02 ± 19 years versus 57.2 ± 1.52 years, p = 0.001 and 62.2 ± 9.2 months versus 40.4 ± 6.4 months, p = 0.04). All LA diameters and LA maximal volume were significantly larger in HTN and AF group (for LA antero-posterior diameter p = 0.02, for all the rest p < 0.0001). LV ejection fraction was preserved in both groups, being significantly lower in HTN and AF patients (58.44 ± 0.79 versus 60.75 ± 0.57, p = 0.02). LV mass was higher in HTN and AF group and these patients had also a more severe diastolic dysfunction, (E/A ratio 1.8 ± 0.51 versus 0.9 ± 0.02, p = 0.04) and lower septal and lateral A′ velocities (p < 0.0001 and p = 0.002). The peak LA longitudinal and contractile strain values were also significantly lower in HTN and AF group versus HTN group (for all p < 0.0001). Among the echocardiographic parameters, we identified PALS and PACS as predictors for AF, with a good discriminating capacity (AUC = 0.88 for PALS and AUC = 0.86 for PACS).
Conclusions
Compared to patients with isolated hypertension, patients with hypertension and AF display several echocardiographic differences. Among them, LA strain parameters could be useful predictors of AF occurrence in hypertensive patients.
