Introduction: international studies have shown that hospital readmissions of patients with cardiovascular diseases (CVD) are related to worse clinical outcomes and increased health costs.

Objective: to estimate one-year survival in patients with multiple admissions for cardiovascular diseases and to compare it with that of those who had a single hospital admission.

Method: a secondary analysis of hospital discharge databases of the Ministry of Public Health of patients over 14 years of age with CVD admissions in 2020 in Uruguay was performed. Two groups were generated: group 1 (G1), people with 1 hospital admission (HI), and group 2 (G2), with 2 or more hospital admissions (HIs). For the survival curves, the Kaplan-Meier method and log-rank test were used.

Results: in 2020, there were 20,354 people with HIs due to CVD alive at discharge. There were 17,499 in G1 (mean age 67.9 ± 15.3 years, 55.1% men) and 2,855 in G2 (mean age 69.7 ± 13.6 years, 58.1% men), with 37,5% of readmissions ≤ 30 days. Survival at one year for G1 vs. G2 was 84.6% vs. 71.7% (95% confidence interval (95% CI): 84.1%; 85.1% vs. 70.1%; 73.4%), p < 0.05>. CVD was the cause of death in 42.2% and 61.6%, respectively, p < 0.05. The adjusted HR of mortality at one year for G2 was 1.86 (95% CI: 1.74; 2.00) compared to G1.

Conclusions: in Uruguay, patients with HIs due to CVD had a worse life prognosis at one year, with an increased risk of death of 86%. CVD was responsible for almost 2/3 of mortality.
