%X <B>OBJECTIVE: </B>To investigate the association between blood pressure (BP) time in range (TIR) and composite cardiovascular outcomes in patients with primary aldosteronism (PA).<BR><B>METHODS: </B>Between January 2019 and December 2021, 47 patients with PA were recruited from the First Affiliated Hospital of Xiamen University. Twenty-four-hour ambulatory BP monitoring (ABPM) and cardiovascular outcomes were assessed in all patients during the first diagnosis of PA.<BR><B>RESULTS: </B>The mean age of the patients was 48.8 ± 11.4 years. Compared to PA without composite cardiovascular outcomes, the nighttime systolic BP TIR [31.2% (6.2%, 81.2%) vs. 11.5% (0.0%, 29.7%), p = 0.02] and defined daily dose (DDDs) of antihypertensive medication [2.0 (1.0, 2.8) vs. 1.0 (1.0, 2.0), p = 0.03] were lower in PA patients with composite cardiovascular outcomes, while higher glucose (5.0 ± 1.0 mmol/L vs. 5.9 ± 1.5 mmol/L) and prevalence of a history of alcohol intake was higher in PA patients with composite cardiovascular outcomes. There were no differences in age, sex, BMI, smoking, duration of hypertension, lipid levels, aldosteronism, clinic BP, 24-hour mean BP, daytime or nighttime BP, percentage of nocturnal SBP or DBP decline, 24-hour BP TIR, daytime BP TIR, or nighttime DBP TIR between the two groups. After adjusting for confounding factors, nighttime systolic BP TIR was significantly associated with composite cardiovascular outcomes (adjusted OR = 0.92 [95% CI 0.86, 0.99]) in multiple logistic regression analysis.<BR><B>CONCLUSIONS: </B>Nighttime systolic BP TIR was significantly associated with composite cardiovascular outcomes in patients with PA.
