Alarmingly Increased Public Interest in “Chest Pain” During the COVID-19 Pandemic: Insights From Google Trends Analysis

Background The coronavirus disease 2019 (COVID-19) pandemic has been linked to a myriad of cardiac symptoms and disorders. Reports also suggest decreased hospital visits by patients with known cardiovascular disorders. Methodology To better elucidate the public interest in the information regarding “chest pain” during the COVID-19 pandemic, we conducted a Google Trends analysis from March 2019 to March 2021 to compare the internet searches between pre-COVID era and during the pandemic with country-wise [the United States (US) versus the United Kingdom (UK) versus India] variation. Results We observed a significantly rising public interest in “chest pain” internet searches during the peak COVID-19 pandemic. Rising trends were most prominent in the UK, followed by USA and India. Our analysis noted a spike in the trend of “chest pain” search in early March in the UK and USA, whereas in March and June 2020 for India. This shows an important temporal association between the surge of COVID-19 cases and the search for “chest pain” online. Conclusion Google Trends analyses indicate rising public interest in chest pain during the pandemic months and the possible association between COVID-19 and chest pain. These findings warrant further research, especially with increasing reports suggesting contradictory reports of decreased hospital visits by patients with known cardiovascular diseases.
