Blood-Pressure Variability Seen to Predict Cognitive Decline

Visit-to-visit variation in systolic blood pressure (BP) and mean heart rate (HR) are both independently related to cognitive dysfunction and decline in patients at high cardiovascular risk, and together their predictive effects are additive, suggests research published online January 12, 2015 in Hypertension. Mean systolic BP didn’t have a significant effect on cognition.

“The take-home message is that HR should be at an optimal rate below 70 bpm, because using beta-blockers [to lower HR] does no harm, especially when a beta-blocker is already indicated as in coronary artery disease or heart failure,” Dr Michael Böhm (Universitatsklinikum des Saarlandes, Homburg/Saar, Germany).
