Key result
Increased left ventricular mass index is linked to a ~3-fold higher risk of ventricular premature beats.
Why the study?
The association between left ventricular remodeling types and cardiac arrhythmias in patients with arterial hypertension has been studied to clarify arrhythmia risk patterns.
Observational
Effect estimate: 1.8-fold to 3-fold increase
In patients with arterial hypertension, specific patterns of left ventricular remodeling are associated with distinct arrhythmias, highlighting the importance of echocardiographic assessment for arrhythmia risk stratification.
Echocardiographic remodeling may aid arrhythmia risk stratification in hypertension; hypothesis-generating and requires prospective validation.
The remodeling types of the left ventricle (LV) and their association with cardiac arrhythmias have been studied in patients with arterial hypertension. Atrial fibrillation predominates in patients with eccentric LV hypertrophy. The risk of atrial fibrillation increases by 1.8 times with the larger sizes of the left atrium Ventricular premature beats are common in patients with he concentric remodeling and concentric hypertrophy of the LV. The increased LV mass index leads to a 3-fold rise- in the risk of ventricular contract beats and to its 1-fold rise when the relative LV wall thickness becomes increased.

Потешкина et al. (2005) conducted an observational in Arterial hypertension. Left ventricular remodeling was evaluated on Cardiac arrhythmias (atrial fibrillation and ventricular premature beats) (1.8-fold to 3-fold increase). Larger left atrial size increased the risk of atrial fibrillation by 1.8 times, and increased left ventricular mass index led to a 3-fold rise in the risk of ventricular premature beats.
