The analysis included 2.28 million adults from five cohort studies conducted in Italy, Germany, the UK, Norway, and Sweden between 1994 and 2010. Participants with and without cardiovascular disease at baseline were included. Data on mortality and new-onset disease were collected through death and disease registries and follow-up surveys. Daily average air temperatures at participants' home addresses were collected from local weather stations orestimated using modeling of temperature data from weather stations.
The analysis found increased risks of death from cardiovascular disease overall and ischaemic heart disease in particular, as well as an elevated risk of new-onset ischaemic heart disease, associated with cold weather. With an approximately 10°C temperature drop, from 5°C to -5°C, there was a 19% greater risk of death from cardiovascular disease. There was a 4% higher risk of new-onset ischaemic heart disease associated with an approximately 11°C temperature drop, from 2°C to -9°C
The heat was not related to detrimental effects on the overall study population. However, the temperature rises from 15°C to 24°C were associated with 25% and 30% elevated risks of death from cardiovascular disease and stroke, respectively, in people with heart disease at baseline.
