Impact of Coronary Intervention on In-Hospital Mortality in Octogenarians and Nonagenarians, Compared to Elderly Patients Aged < 80 Years with Acute Coronary Syndromes.

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
Background: Given that the Australian population is aging, with older patients presenting with acute coronary syndrome (ACS), its management over the past 20 years is likely to have changed. Methods: Retrospective observational study from the New South Wales statewide Admission Patient Data Collection database of those aged ≥ 65 years hospitalized for ACS between January 2002 and December 2021. Patients were stratified into 3 age groups: 65-79 years, 80-89 years, ≥ 90 years). Temporal trends of ACS, coronary angiogram (CA), and percutaneous coronary intervention (PCI) and in-hospital mortality were evaluated. Multivariable analysis was used to adjust for baseline profiles and year of admission in mortality analysis. Results: The study cohort comprised 118,608 patients (56.7% aged 65-79 years [n = 67,211]; 34.1% aged 80-89 years [n = 40,452]; 9.2% aged ≥ 90 years [n = 10,945]). Those aged 65-79 years, compared to older groups, had proportionally more male patients, with higher rates of ischemic heart disease, diabetes, smoking history, prior PCI and/or surgical bypass revascularization, and obesity. Heart failure, chronic pulmonary and renal disease, and dementia were more common in the older age groups. Proportionally, ST-elevation myocardial infarction decreased over time, whereas non-ST-elevation myocardial infarction rates increased. Although fewer CAs were performed in the older age groups, PCI rates in those who had CA were higher in those aged ≥ 80 years. Multivariable analysis showed that in-hospital mortality fell 49% in the group admitted in 2017 or later, vs in 2006 or earlier; for the younger, vs the older age groups, mortality fell by 55.4%, 52.5%, and 44.6%, respectively. The group aged ≥ 90 years had 3.1-fold higher adjusted odds of in-hospital death, compared to the group aged 65-79 years. Conclusions: Over the past 2 decades, with increasing rates of coronary intervention, rates of in-hospital mortality in the elderly decreased, but older patients continue to have poorer outcomes following ACS.
