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.

Due to the significant spread of a new type of coronavirus (SARS-CoV-2) infection (COVID-19) in China, the Chinese government blockaded several cities in Hubei Province. Japanese citizens lost a means of transportation to return back to Japan. The National Center for Global Health and Medicine (NCGM) helped the operation of charter flights for evacuation of Japanese residents from Hubei Province, and this article outlines our experiences. A total of five charter flights were dispatched, and the majority of returnees (793/829 [95.7%]) were handled at NCGM. A large number of personnel from various departments participated in this operation; 107 physicians, 115 nurses, 110 clerical staff, and 45 laboratory technicians in total. Several medical translators were also involved. In this operation, we conducted airborne precautions in addition to contact precautions. Eye shields were also used. The doctors collecting the pharyngeal swab used a coverall to minimize the risk of body surface contamination from secretions and droplets. Enhanced hand hygiene using alcohol hand sanitizer was performed. Forty-eight persons were ultimately hospitalized after the triage at NCGM operation, which was more than the number of persons triaged at the airport (n = 34). Of those hospitalized after NCGM triage, 8.3% (4/48 patients) ultimately tested positive for SARS-CoV-2, significantly higher than the positive rate among subjects not triaged (4/48 [8.3%] vs. 9/745 [1.2%]: p = 0.0057). NCGM participated in a large-scale operation to evacuate Japanese nationals from the COVID-19 epidemic area. We were able to establish a scheme through this experience that can be used in the future.

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.

The prognosis has improved remarkably in recent years with the development of cancer treatment. With the increase in the number of cancer survivors, complications of cardiovascular disease have become a problem. Therefore, the field of onco-cardiology has been attracting attention. The field of onco-cardiology covers a wide range of areas. In the past, cardiac dysfunction caused by cardiotoxic drug therapies such as doxorubicin (Adriamycin) was the most common cause of cardiac dysfunction, but nowadays, cardiovascular complications caused by aging cancer survivors, atherosclerotic disease in cardiovascular risk carriers, thromboembolism, and new drugs (e.g., myocarditis caused by immune checkpoint inhibitors and hypertension caused by angiogenesis) are becoming more common. In this review, we summarize the latest findings of cardiotoxicity of cancer therapy, appropriate treatment and prevention, and cardiovascular complications of novel chemotherapy, which will increase in demand in the near future.

1 0 0 0 OA IgG4-Related Cardiovascular Disorders

Immunoglobulin4 (IgG4)-related disease is a systemic inflammatory disease characterized by elevation of serum IgG4. It involves various organs such as the pancreas (autoimmune pancreatitis), lacrimal gland (Mikulicz’s disease), retroperitoneum (retroperitoneal fibrosis), aorta (aortic aneurysm and aortitis), heart (constrictive pericarditis), and pseudotumors around the coronary arteries. These disorders often coexist in accordance with progression of the disease. Because IgG4-related cardiovascular disorder affects the patient’s prognosis, early detection and treatment is important. Coronary CT imaging and echocardiography accidentally detect IgG4-related disorders and 18FDG-PET imaging can identify active inflammation in the lesions. Measurement of serum IgG4 levels and tissue biopsy are necessary for diagnosis. Minor salivary gland biopsy is recommended even though 18FDG uptake is not detected when it is difficult to obtain a biopsy specimen from IgG4-related cardiovascular lesions. The first-line treatment is high-dose corticosteroid therapy, however, relapse is often reported. Corticosteroids suppress the development of active inflammatory diseases such as aortitis, pericarditis, and pseudotumors, but already-developed lesions do not respond. A large developed aneurysm can rupture even during or after corticosteroid therapy, therefore, additional surgical treatment may be needed. Treatment of IgG4-related cardiovascular disorders might require higher doses of corticosteroids than IgG4-related extracardiovascular disorders. The adequate dose of corticosteroid, type and dose of immunosuppressant, and surgical intervention should be carefully considered on a case-by-case basis.
