Background:Several studies have reported elevated troponin levels in coronavirus disease 2019 (COVID-19) patients, so we investigated myocardial damage by measuring high-sensitivity troponin T (hsTnT) levels and analyzed the relationship with comorbidities.Methods and Results:Of 209 patients who recently recovered from COVID-19, 65% had an elevated hsTnT level that was higher than levels in patients with acute phase infection despite most patients (79%) having a mild illness. The hsTnT levels correlated with disease severity, sex, comorbidities, and ACEi and ARB use.Conclusions:Myocardial damage occurs in the recovery phase of COVID-19, and its evaluation, regardless of patient age, should be considered.

Background: Patients with atrial fibrillation (AF) and heart failure (HF) have elevated left ventricular end-diastolic pressure in addition to decreased left atrial (LA) function, but there are few reports of useful prognostic indices that can be seen on echocardiography. In this study, we investigated the association between LA reservoir strain (LARS) and prognosis in this group of patients.Methods and Results: We retrospectively enrolled patients with acute HF complicated by AF who were consecutively admitted to hospital between January 2014 and December 2018. A total of 320 patients (mean age 79±12 years, 163 women) were included in the analysis. During a median follow-up of 473 days, 92 cardiovascular deaths and 113 all-cause deaths occurred. In the multivariate analysis, LARS was an independent predictor of all-cause death (hazard ratio [HR] 0.94, 95% confidence interval [CI] 0.90–0.99, P=0.016). Multivariate analysis also showed that the patients in the lowest LARS tertile (<7.16%) had a significantly increased risk of cardiovascular death (HR 1.76, 95% CI 1.05–2.96; P=0.033) and all-cause death (HR 1.90, 95% CI 1.17–3.08; P=0.009) in comparison with patients in the highest LARS tertile (>10.52%).Conclusions: We found a significant association between LARS and death in patients with AF and HF. Patients with reduced LARS had poor prognosis, suggesting the need for aggressive therapy to improve their LA dysfunction.

The aim of this study is to investigate myocardial damage in recovering coronavirus disease 2019 (COVID-19) patients with high-sensitivity troponin levels (hsTnT) and echocardiography. In this single-center cohort study, 215 COVID-19 recovered patients were recruited from all over Japan between April and September 2020. Demographic characteristics, hsTnT levels, and echocardiography data were collected for 209 patients, after excluding those without serum samples or good-quality echocardiographic images. The mean (± standard deviation) age was 44 (± 12) years (range: 36-55 years), and 50.7% of the patients were males. The median time interval (interquartile range) from COVID-19 onset to post-recovery examination was 56 days (34-96 days). Seventy-four recovered patients (35.4%) had hsTnT less than detection sensitivity (< 3 pg/mL) and 135 recovered patients (64.6%) had hsTnT ≥ 3 pg/mL. Ejection fraction was more than 50% in all cases. Left ventricular global longitudinal strain (LVGLS) and right ventricular free-wall longitudinal strain (RVFWLS) were reduced in 62 (29.7%) and 8 patients (3.8%), respectively. They were significantly associated with elevated hsTnT levels. In cases with hsTnT above 5 pg/mL, the LVGLS was greatly reduced to 19.0 ± 2.2% (p < 0.001). Multivariate linear regression analysis showed that elevated hsTnT level was an independent predictor of reduced LVGLS (standardized β = -0.34; p < 0.001). In recovered COVID-19 patients, even a slight increase in hsTnT above detection sensitivity was associated with decreased LVGLS. hsTnT and echocardiography may be useful tools to detect myocardial injury in recovered COVID-19 patients.
