Key result
Ambient air pollution and higher temperatures are linked to increased readmissions for MI and stroke.
Why the study?
Does intermediate and long-term exposure to ambient air pollution and temperature increase the risk of hospital admissions for second cardiovascular events in Medicare beneficiaries?

Answers are grounded in this paper and cite their sources.
Exposure to ambient air pollution and higher temperatures is associated with an increased risk of recurrent cardiovascular events, highlighting the environmental impact on cardiovascular health.
BACKGROUND: Air pollution has been linked to cardiovascular diseases (CVDs). In this study, we assess whether exposure to air pollutants and ambient temperature is associated with repeated admissions with adverse cardiovascular outcomes. METHODS: < 50 ppb. RESULTS: exhibited a slight protective effect for both outcomes. Higher temperatures were associated with a higher hazard of second admissions with stroke. These results persisted at lower concentrations. CONCLUSION: are associated with increased rates of second admissions with MIs and strokes. Higher temperatures were also further associated with an increase in the rate of second admissions with stroke.

Yazdi et al. (2025) conducted an observational in Cardiovascular diseases. Ambient air pollution and temperature was evaluated on Second hospital admissions with myocardial infarctions and strokes. Exposure to ambient air pollution and higher temperatures is associated with increased rates of second hospital admissions for myocardial infarctions and strokes among Medicare beneficiaries.
