Key result
In patients with hypertensive heart failure, valvular regurgitations were associated with significantly more supraventricular tachycardia (81 vs 4.4 episodes/24h; P=0.016) and ventricular arrhythmias.

May warrant arrhythmia monitoring in hypertensive HF with regurgitations; leaves open whether valvular intervention reduces events.
Observational (n=46)
Does the presence of valvular regurgitations increase the risk of cardiac arrhythmias in patients with hypertensive heart failure?
Absolute Event Rate: 81% vs 4.4%
p-value: p=0.016
Multivalvular regurgitations in hypertensive heart failure are associated with a significantly increased burden of supraventricular and complex ventricular arrhythmias.
Ajayi et al. (2012) conducted an observational in Hypertensive heart failure and hypertensive heart disease (n=46). Valvular regurgitations (VHD) vs. Absence of valvular regurgitations (NVHD) was evaluated on Mean supraventricular tachycardia (SVT) episodes per 24 hours (p=0.016). In patients with hypertensive heart failure, valvular regurgitations were associated with significantly more supraventricular tachycardia (81 vs 4.4 episodes/24h; P=0.016) and ventricular arrhythmias.
