Background The 2022 Ukraine-Russian War has led to significant anxiety, anguish, and trauma among the people in Ukraine. The objective of this study was to analyze the Google Trend results of common cardiac symptoms in Ukraine, Russia, and worldwide in 2022 and compare that to 2021 with the hypothesis that common cardiac symptoms in the war-affected regions would be higher compared to the rest of the world. We hypothesize that the search trends of cardiac symptoms would increase in Ukraine given the turmoil caused by the Russian invasion. Methods We queried Google Trends for common cardiac symptoms such as chest pain, dizziness, palpitations, syncope, etc. Google Trends provides results as relative search volume (RSV) displayed in a geographical format. The RSV ranges from 0 to 100, with 0 indicating that the search term is not popular, and 100 indicating the search term's popularity is at its peak. Google Trends of cardiac symptoms in Russia, Ukraine, and worldwide was taken two weeks before and after February 24, 2022, compared with the same period in 2021. To assess the difference in Google Trends between the study periods in 2022 and 2021, the paired t -test was used. Results Overall, Google Trends for cardiac symptoms was lower in Ukraine and Russia than worldwide, in both 2021 and 2022 during the study period. There was a significant reduction in search for chest pain (14 vs. 30.5; p<0.049), pedal edema (40.0 vs 66.6; p approaching 0), and syncope (37.8 vs. 58.4; p<0.002) in Ukraine during the study periods in 2022 compared to 2021. There was a decrease in the searches for dyspnea (44.6 vs. 55.4; p<0.029) in Russia and for dizziness (87.6 vs. 92.8; p<0.005) worldwide. There was an increase in the searches for edema (93.6 vs. 91; p <0.002) and for fatigue (88.6 vs 79.5; p approaching 0) worldwide in study periods in 2022 as compared to 2021. There was no other significant difference between cardiac symptom search trends during the periods evaluated in Ukraine, Russia, and worldwide. Conclusion There appears to be a significant reduction in searching for a few cardiovascular symptoms, namely, chest pain, pedal edema, and syncope in Ukraine, which may be due to a focus on other immediate problems related to war and the availability of the Internet.
