Objective:
Older age and cardiovascular comorbidities are well-known risk factors for all-cause mortality in COVID-19 patients. Hypertension (HT) and age are the two principal determinants of arterial stiffness (AS). The objective of this study is to estimate AS in COVID-19 patients requiring hospital admission and analyze its association with all-cause mortality.
Design and method:
This cross-sectional, observational, retrospective multicenter study includes 122170 patients who required hospital admission in 150 Spanish centers, included in the nationwide SEMI-COVID-19 Network. We compared estimated AS as pulse pressure > 60 mmHg and compared clinical characteristics between survivors and nonsurvivors.
Results:
Mean age was 67.5 ± 16.1 years, 42.5% were women. Most patients were white (90.0%). Globally, 2606 (21.4%) subjects died. Blood pressure (BP) < 120 mmHg and BP > 140 at admission predicted higher all-cause mortality (23.5% and 22.8%, respectively, p < 0.001), compared to BP between 120–140 mmHg (18.6%). 4379 patients with AS (36.0%) were older and had higher systolic and lower diastolic BP. Multivariate analysis showed that even adjusting for gender (males, OR: 1.6, p = 0.0001), age tertiles (second and third tertiles, OR: 2.0 and 4.7, p = 0.0001), Charlson-Index (second and third tertiles, OR: 4.8 and 8.6, p = 0.0001), heart failure, previous and in-hospital antihypertensive treatment, AS and BP < 120 mmHg significantly and independently predicted all-cause mortality (OR: 1.27, p = 0.0001 and OR: 1.48, p = 0.0001, respectively).
Conclusions:
Our data show that arterial stiffness, defined as pulse pressure above 60 mmHg at hospital admission, and BP at admission < 120 mmHg were important determinants with independent prognostic value for all-cause mortality in COVID-19 patients requiring hospitalization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
