Aggressive BP-lowering ‘can stave off’ conduction disorders
Treating to a target of <120mmHg systolic BP was linked to a lower risk of left ventricular conduction disease
Intensive blood pressure treatment lowers the risk of left ventricular conduction disease in older adults with hypertension, according to US and Danish researchers.
Their findings, published in JAMA Cardiology, suggest that cardiac conduction disease may be a modifiable outcome “susceptible to prevention strategies”.
In their post-hoc analysis of the Systolic Blood Pressure Intervention Trial (SPRINT), the team analysed outcomes data from 8000 patients (mean age 68) with hypertension who were randomly treated to standard target of <140mmHg systolic BP or intensive target of <120mmHg systolic BP.
During an average 3.5 years’ follow-up, 203 participants developed left ventricular conduction disease as assessed by serial ECG.
