Key result
Elderly patients (≥80 years) with COVID-19 had a significantly higher risk of in-hospital mortality (approximately 30%) compared to younger patients, regardless of cardiovascular comorbidities.
Why the study?
The study investigated the effects of age on COVID-19 outcomes and cardiac biomarker profiles, particularly in patients with cardiovascular diseases and/or risk factors.
Does advanced age (≥80 years) increase the risk of in-hospital mortality and cardiac biomarker elevation in COVID-19 patients with cardiovascular diseases and/or risk factors?
Cohort (n=1,518)
Yes
Does advanced age (≥80 years) increase the risk of in-hospital mortality and cardiac biomarker elevation in COVID-19 patients with cardiovascular diseases and/or risk factors?
In patients with COVID-19, advanced age (≥80 years) is associated with a higher risk of in-hospital mortality and elevated cardiac biomarkers, independent of underlying cardiovascular diseases or risk factors.

Age ≥80 years flags higher COVID-19 mortality and cardiac biomarker elevations; leaves open incremental prognostic value in CVDRF patients.
BACKGROUND: This study investigated the effects of age on the outcomes of coronavirus disease 2019 (COVID-19) and on cardiac biomarker profiles, especially in patients with cardiovascular diseases and/or risk factors (CVDRF). METHODS AND RESULTS: A nationwide multicenter retrospective study included 1,518 patients with COVID-19. Of these patients, 693 with underlying CVDRF were analyzed; patients were divided into age groups (<55, 55-64, 65-79, and ≥80 years) and in-hospital mortality and age-specific clinical and cardiac biomarker profiles on admission evaluated. Overall, the mean age of patients was 68 years, 449 (64.8%) were male, and 693 (45.7%) had underlying CVDRF. Elderly (≥80 years) patients had a significantly higher risk of in-hospital mortality regardless of concomitant CVDRF than younger patients (P<0.001). Typical characteristics related to COVID-19, including symptoms and abnormal findings on baseline chest X-ray and computed tomography scans, were significantly less prevalent in the elderly group than in the younger groups. However, a significantly (P<0.001) higher proportion of elderly patients were positive for cardiac troponin (cTn), and B-type natriuretic peptide (BNP) and N-terminal pro BNP (NT-proBNP) levels on admission were significantly higher among elderly than younger patients (P<0.001 and P=0.001, respectively). CONCLUSIONS: Elderly patients with COVID-19 had a higher risk of mortality during the hospital course, regardless of their history of CVDRF, were more likely to be cTn positive, and had significantly higher BNP/NT-proBNP levels than younger patients.

Matsumoto et al. (2021) conducted a cohort in COVID-19 with cardiovascular diseases and/or risk factors (n=1,518). Older age (≥80 years) vs. Younger age (<80 years) was evaluated on In-hospital mortality (p=<0.001). Elderly patients (≥80 years) with COVID-19 had a significantly higher risk of in-hospital mortality (approximately 30%) compared to younger patients, regardless of cardiovascular comorbidities.
