Less air pollution did not explain the decline in admissions for AMI during the first wave of COVID-19 pandemic in Sardinia, Italy.

During the COVID-19 pandemic, hospitalizations for acute myocardial infarction (AMI) decreased worldwide. We compared the admissions for AMI in the four regional 24/7 cath lab during the national lockdown, the 8 weeks before the lockdown, the 8 weeks after the e lockdown, and the corresponding time period in 2019 and we analyzed the average level of pollution in the studies areas. A marked decline in AMI admissions was observed during the lockdown period in comparison with the 8 weeks before the lockdown (p < 0.0001) and a significant increase in the 8 weeks after the lockdown (p < 0.00001). No significant change in air pollutants density were highlighted. Since air pollution did not change substantially in our region, the environment factor cannot explain the decline in the number of admissions for AMI we recorded during the lockdown. Fear of contagion is the most plausible reason for the drop of hospitalizations during the lockdown period.

Acute cardiovascular events triggered by the COVID-19 pandemic-related stress in non-infected individuals. The Jordan COVID-19 Acute Cardiovascular Events (JoCORE) study.

The Corona Virus Disease 2019 (COVID-19) has become an unprecedented global public health crisis and a pandemic associated with vicarious psychosocial and economic stresses. Such stresses were reported to lead to behavioral and emotional disturbances in individuals not infected with the COVID-19 virus. It is largely unknown if these stresses can trigger acute cardiovascular events (CVE) in such individuals. Covid-19-neagtive adults presenting with acute myocardial infarction (AMI), cerebrovascular accident (CVA), or out-of-hospital cardiac arrest (OHCA) during the COVID-19 pandemic in Jordan from March 15, 2020 through March 14, 2021 were enrolled in the study if they reported exposure to psychosocial or economic stresses related to the pandemic lockdown. Of 300 patients enrolled (mean age 58.7 ± 12.9 years), AMI was diagnosed in 269 (89.7%) patients, CVA in 15 (5.0%) patients, and OHCA in 16 (5.3%) patients. Triggering events were psychosocial in 243 (81.0%) patients and economic stressors in 157 (52.3%) patients. The psychosocial stresses included loneliness, hopelessness, fear of COVID-19 infection, anger, and stress-related to death of a significant person. The economic stressors included financial hardships, job loss or insecurity, volatile or loss of income. Exposure to more than one trigger was reported in 213 (71.0%) patients. In-hospital mortality of the patients admitted for AMI or CVA was 2.1%, and none of the OHCA survived the event. The COVID-19 pandemic continues to be a source of significant psychosocial and economic hardships that can trigger life-threatening acute CVE among individuals not infected with the virus.
