Background: Nocturnal Hypertension (NHT) has an impact on cardiovascular morbidity and mortality. Our aim was to evaluate the association between NHT and cardiovascular events. Methods: We carried out a retrospective cohort study including adults which had an ambulatory blood pressure monitoring test between March 2017 and July 2020 at a hospital in Buenos Aires City Argentina, with up to 36 months follow-up. Univariate and multivariate analyzes were performed to identify associated factors. Results: Four hundred and ninety four patients were included in the final analysis, 48% male, average age 58.9 years. Sixty two percent (n=308) presented NHT. A higher incidence of the cardiovascular composite endpoint was found in this group compared to those who did not present it, 10.4% vs 3.8% (p=0.013). In the final multivariate Cox regression analysis NHT was an independent predictor of cardiovascular events (HR= 3.9; 95% CI 1.56–9.81; p= 0.001), even independently of daytime HTN and the different circadian patterns of pressure. Conclusions: In this contemporary cohort from Buenos Aires, NHT was related to cardiovascular events incidence. Different measures should be taken to increase NHT awareness and diagnosis.
