Radiological and pathological studies in severe COVID-19 pneumonia (SARS-CoV-2) have demonstrated extensive pulmonary immunovascular thrombosis and infarction. This study investigated whether these focal changes may present with chest pain mimicking pulmonary emoblism (PE) in ambulant patients. ⋯ 32.8% ambulatory patients with suspected PE in 2020 had parenchymal changes with 7.5% diagnosed as COVID-19 infection by imaging criteria, despite the absence of other COVID-19 symptoms. These findings suggest that localized COVID-19 pneumonitis with immunothrombosis occurs distal to the bronchiolar arteriolar circulation, causing pleural irritation and chest pain without viraemia, accounting for the lack of fever and systemic symptoms.

As opposed to the decreasing overall rates of coronary heart disease (CHD) incidence and overall cardiovascular disease (CVD) mortality, heart failure (HF) and stroke incidence are increasing in young people, potentially due to rising rates of obesity and reduced cardiorespiratory fitness (CRF). ⋯ Secular trends of young-onset CVD events demonstrated a marked shift from AMI and CVD mortality to HF and stroke incidence. Trends were significantly, though moderately, influenced by changing baseline BMI and CRF.
