Abstract
AIMS We investigated the associations between time in target range (TTR) of blood pressure (BP) and cardiovascular outcomes in patients with diabetes. METHODS 4651 participants from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) BP trial were included in the present study. The diastolic BP target range was defined as 70 to 80 mm Hg, and the systolic as 120 to 140 mm Hg and 110 to 130 mm Hg for the standard and intensive therapy, respectively. RESULTS After adjusting for covariates, 1-SD increase of diastolic TTR was significantly associated with lower risks of primary outcome (HR 0.82, 95% CI: 0.74-0.91, P < 0.001; HR 0.86, 95% CI: 0.77-0.95, P = 0.0044, as well as nonfatal myocardial infarction (HR 0.79, 95% CI: 0.69-0.91, P < 0.001). Meanwhile, systolic TTR was significantly associated with various cardiovascular outcomes (P ≤ 0.016) in fully-adjusted models. The diastolic TTR sustained significance in myocardial infarction when systolic blood pressure average was higher than 120 mm Hg. CONCLUSIONS In patients with diabetes, TTR of diastolic and systolic BP was independently associated with lower risks of major outcomes. The diastolic BP within the optimal target range was considerably important for reducing the risk of myocardial infarction, even when systolic BP was under stable control.
