Long-term cardiovascular events in individuals hospitalised with COVID-19: a retrospective cohort.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPost-COVID condition encompasses a spectrum of persistent or emerging symptoms affecting multiple organ systems, including a heightened risk of cardiovascular complications. Despite growing recognition of this phenomenon, there remains a lack of comprehensive data regarding the incidence and risk factors associated with cardiovascular events during the post-acute phase in patients previously hospitalised for COVID-19. Thus, we aimed to estimate the incidence of cardiovascular events among patients hospitalised for COVID-19 in Portugal and assess the association between patient and infection characteristics and cardiovascular events in the COVID-19 post-acute phase.
methodsWe conducted a registry-based retrospective cohort study from seven hospitals across Portugal. Data was retrospectively collected from the electronic medical record of each patient. We included individuals hospitalised due to COVID-19 between March 2020 and March 2021. Our outcome of interest was cardiovascular events in the post-acute phase of COVID-19, occurring at least 30 days after a positive SARS-CoV-2 test. The variables of interest considered were the severity of the episode, existing cardiovascular risk and vaccination status before the SARS-CoV-2 test. Person-years was estimated for each individual, and incidence rates were estimated. A Cox proportional hazard regression model was employed to assess risk factors.
resultsWe included 1,803 patients in the analysis, of which 143 (7.9%) experienced at least one cardiovascular event following COVID-19 hospitalisation. The overall incidence rate of having at least one cardiovascular event was 34.65 per 1,000 person-years (95% confidence interval (CI): 29.20; 40.82). We found higher risk of cardiovascular events for individuals with pre-existing cardiovascular risk (adjusted hazard ratio (aHR): 3.76, 95% CI: 1.53; 9.24) and lower risk for individuals with at least one vaccine dose before the SARS-CoV-2 test (partial vaccination - aHR: 0.44, 95%CI: 0.30; 0.64, complete vaccination - aHR: 0.46, 95%CI: 0.2; 0.80). We did not find a significant difference between the severity of the COVID-19 episode and the risk of having cardiovascular events post-COVID-19.
conclusionOur findings suggest a substantial burden of cardiovascular complications post-COVID-19, underscoring the need for health services to be prepared and commence screening and preventive measures for individuals at higher risk.
