Lifetime obesity trends are associated with subclinical myocardial injury: The Trøndelag health study
Background
Obesity is associated with subclinical myocardial injury as quantified by concentrations of cardiac troponin T, but whether lifetime excess weight history is associated with increased concentrations of cardiac troponin I (cTnI) and how indices of abdominal adiposity and glycemic dysregulation affect these associations remain unclear.
Methods
We analyzed cTnI with a high-sensitivity assay in 9739 participants in the Trøndelag Health (HUNT) Study at study visit 4 (2017–2019). BMI was assessed at study Visit 1 (1984–1986), 2 (1995–1997), 3 (2006–2008), and 4.
Results
Median age at visit 4 was 68.7 years and 59% were women. Concentrations of cTnI were detectable in 84.1% of study participants, with a median of 2.5 (1.5–4.5 ng/L). We identified three clusters of BMI trajectories from visit 1 to 4, (1) stable normal weight, (2) stable overweight, and (3) stable obesity. Participants in clusters 2 and 3 were at increased risk of elevated concentrations of cTnI at visit 4 (odds ratio 1.27, 95% CI 1.09–1.47, and odds ratio 1.70, 95% CI 1.33–2.17, p for trend <0.001). Participants in cluster 3 had 22.0 (95% CI 14.1–29.9) higher concentrations of cTnI compared to participants in cluster 1 (p for trend <0.001). Dysregulated glucose metabolism and abdominal obesity did not influence our results.
Conclusions
Individuals with stable overweight or obesity are at increased risk of subclinical myocardial injury, independently of glycemic dysregulation and abdominal adiposity. Our data support a direct detrimental effect of long-standing obesity on cardiovascular health

Clinical, radiographic, and pathologic abnormalities in dogs with multiple epiphyseal dysplasia: 19 cases (1991–2005)
Cardiac pathology 6 months after hospitalization for COVID-19 and association with the acute disease severity
Background
Coronavirus disease 2019 (COVID-19) may cause myocardial injury and myocarditis, and reports of persistent cardiac pathology after COVID-19 have raised concerns of long-term cardiac consequences. We aimed to assess the presence of abnormal cardiovascular resonance imaging (CMR) findings in patients recovered from moderate-to-severe COVID-19, and its association with markers of disease severity in the acute phase.
Methods
Fifty-eight (49%) survivors from the prospective COVID MECH study, underwent CMR median 175 [IQR 105-217] days after COVID-19 hospitalization. Abnormal CMR was defined as left ventricular ejection fraction (LVEF) <50% or myocardial scar by late gadolinium enhancement. CMR indices were compared to healthy controls (n = 32), and to circulating biomarkers measured during the index hospitalization.
Results
Abnormal CMR was present in 12 (21%) patients, of whom 3 were classified with major pathology (scar and LVEF <50% or LVEF <40%). There was no difference in the need of mechanical ventilation, length of hospital stay, and vital signs between patients with vs without abnormal CMR after 6 months. Severe acute respiratory syndrome coronavirus 2 viremia and concentrations of inflammatory biomarkers during the index hospitalization were not associated with persistent CMR pathology. Cardiac troponin T and N-terminal pro-B-type natriuretic peptide concentrations on admission, were higher in patients with CMR pathology, but these associations were not significant after adjusting for demographics and established cardiovascular disease.
Conclusions
CMR pathology 6 months after moderate-to-severe COVID-19 was present in 21% of patients and did not correlate with severity of the disease. Cardiovascular biomarkers during COVID-19 were higher in patients with CMR pathology, but with no significant association after adjusting for confounders.
