Background Cardiovascular involvement in coronavirus disease 2019 (COVID‐19) is common and leads to worsened mortality. Diagnostic cardiovascular studies may be helpful for resource appropriation and identifying patients at increased risk for death. Methods and Results We analyzed 887 patients (aged 64±17 years) admitted with COVID‐19 from March 1 to April 3, 2020 in New York City with 12 lead electrocardiography within 2 days of diagnosis. Demographics, comorbidities, and laboratory testing, including high sensitivity cardiac troponin T (hs‐cTnT), were abstracted. At 30 days follow‐up, 556 patients (63%) were living without requiring mechanical ventilation, 123 (14%) were living and required mechanical ventilation, and 203 (23%) had expired. Electrocardiography findings included atrial fibrillation or atrial flutter (AF/AFL) in 46 (5%) and ST‐T wave changes in 306 (38%). 27 (59%) patients with AF/AFL expired as compared to 181 (21%) of 841 with other non‐life‐threatening rhythms ( P <0.001). Multivariable analysis incorporating age, comorbidities, AF/AFL, QRS abnormalities, and ST‐T wave changes, and initial hs‐cTnT ≥20 ng/L showed that increased age (HR 1.04/year), elevated hs‐cTnT (HR 4.57), AF/AFL (HR 2.07), and a history of coronary artery disease (HR 1.56) and active cancer (HR 1.87) were associated with increased mortality. Conclusions Myocardial injury with hs‐cTnT ≥20 ng/L, in addition to cardiac conduction perturbations, especially AF/AFL, upon hospital admission for COVID‐19 infection is associated with markedly increased risk for mortality than either diagnostic abnormality alone.

Increased levels of plasma troponins and natriuretic peptides in the general population are associated with increased future risk of cardiovascular disease, but only limited information exists on these biomarkers and stroke occurrence. In a prospective epidemiological study, the Atherosclerosis Risk in Communities (ARIC) Study, we tested the hypothesis that high-sensitivity troponin T (TnT) and N-terminal pro B-type natriuretic peptide (NT-proBNP) are associated positively with incidence of stroke. We measured plasma high-sensitivity TnT and NT-proBNP in 10,902 men or women initially free of stroke and followed them for a mean of 11.3 years for stroke occurrence (n=507). Analyses were performed using proportional hazards modeling. Both biomarkers were associated positively with total stroke, nonlacunar ischemic, and especially, cardioembolic stroke, but not with lacunar or hemorrhagic stroke. After adjustment for other stroke risk factors, the hazard ratio (95% CI) per one SD greater increment of natural log-transformed TnT was 1.23 (1.13, 1.35) for total stroke, 1.27 (1.15, 1.40) for total ischemic stroke, and 1.36 (1.14, 1.62) for cardioembolic stroke. Likewise, the hazard ratio per one SD greater natural log-transformed NT-proBNP, was 1.37 (1.26, 1.49) for total stroke, 1.39 (1.27, 1.53) for total ischemic stroke, and 1.95 (1.67, 2.28) for cardioembolic stroke. The hazard ratios for jointly high values of TnT (≥0.013 ug/L) and NT-proBNP (≥155.2 pg/mL), versus neither biomarker high, were 2.70 (1.92, 3.79) for total stroke and 6.26 (3.40, 11.5) for cardioembolic stroke, and somewhat stronger for NT-proBNP than TnT. Strikingly, approximately 58% of cardioembolic strokes occurred in the highest quintile of pre-stroke NT-proBNP (versus 3% occurring in the lowest quintile), and 32% of cardioembolic strokes occurred in participants who had both NT-proBNP in the highest quintile and were known by ARIC to have atrial fibrillation sometime before their cardioembolic stroke occurrence. In conclusion, in the general population, elevated plasma TnT and NT-proBNP concentrations are associated with increased risk of cardioembolic and other nonlacunar ischemic strokes.

Background: We assesse the evolution and prognostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP) and high-sensitivity troponin T (cTnT-HS) in transthyretin amyloid cardiomyopathy (ATTR-CA) before and after tafamidis treatment. Methods and Results: 454 ATTR-CA patients without tafamidis (Cohort A) and 248 ATTR-CA with tafamidis (Cohort B) were enrolled. Event-free survival (EFS) events were death, heart transplant, or acute heart failure. In Cohort A, 27% of patients maintained NT-proBNP < 3000 ng/L and 14% cTnT-HS < 50 ng/L at 12 months relative to baseline levels. In Cohort B, the proportions were 49% and 29%, respectively. In Cohort A, among the 333 patients without an increased NT-proBNP > 50% relative to baseline EFS was extended compared to the 121 patients with an increased NT-proBNP > 50% (HR: 0.75 [0.57; 0.98]; p = 0.032). In Cohort A, baseline NT-proBNP > 3000 ng/L and cTnT-HS > 50 ng/L and a relative increase of NT-proBNP > 50% during follow-up were independent prognostic factors of EFS. The slopes of logs NT-proBNP and cTnT-HS increased with time before and stabilized after tafamidis. Conclusion: ATTR-CA patients with increasing NT-proBNP had an increased risk of EFS. Tafamidis stabilize NT-proBNP and cTnT-HS increasing, even if initial NT-proBNP levels were >3000 ng/L. Thus suggesting that all patients, irrespective of baseline NT-proBNP levels, may benefit from tafamidis.

Introduction: Elevated plasma levels of lipoprotein(a) [Lp(a)] are associated with increased risk for coronary artery disease (CAD), but the strength of the association and whether it is independent of other risk factors remains controversial. Differences in prospective studies may be partially explained by variability in methods used to measure Lp(a). Methods: We utilized two different analytical methods (electrophoretic and immunologic) to measure Lp(a) and determine the predictive value of Llp(a) in assessing angiographic coronary artery disease (CAD) and association with major adverse events in 500 patients. Results: In univariate analyses, median Lp(a) cholesterol and Lp(a) mass were significantly associated with angiographic CAD. In a multivariable model, Lp(a) cholesterol remained a significant correlate of CAD (OR 1.61, 95% CI 1.13-2.31, P = 0.009) while Lp(a) mass was not (OR 1.18, 95% CI 0.95-1.47, P = 0.14). Additionally, on multivariable analysis, the presence of a detectable amount of Lp(a) cholesterol (> or =2.5 mg/dL) was more strongly correlated with CAD than HDL cholesterol < 40 mg/dL, and, along withLp(a) cholesterol, was strongly correlated with major adverse events (OR 2.08 95% CI 1.22-3.56, P = 0.007 and OR 1.22, 95% CI 1.05-1.42, P = 0.012, respectively). Conclusions: Lp(a) cholesterol measured electrophoretically is independently correlated with angiographic CAD and presence of major adverse events, and may be used as an alternative or supplement to Lp(a) mass analysis.

Objective: The aim of this study was to determine the independent value of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein to predict onset of cardiopulmonary disease in a large, multi-center systemic sclerosis cohort followed prospectively. Methods: Subjects from the Canadian Scleroderma Research Group registry with data on N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were identified. Outcomes of interest were death, systolic dysfunction (left ventricular ejection fraction < 50% or medications for heart failure), pulmonary arterial hypertension by right heart catheterization, pulmonary hypertension by cardiac echocardiography (systolic pulmonary artery pressures ⩾ 45 mmHg), arrhythmias (pacemaker/implantable cardiac defibrillator or anti-arrhythmic medications), and interstitial lung disease. Multivariate Cox proportional hazard models were generated for each outcome. Results: A total of 675 subjects were included with a mean follow-up of 3.0 ± 1.8 years. Subjects were predominantly women (88.4%) with mean age of 58.2 ± 11.3 years and mean disease duration of 13.7 ± 9.1 years. One hundred and one (101, 15%) subjects died during follow-up, 37 (6.4 %) developed systolic dysfunction, 18 (2.9%) arrhythmias, 34 (5.1%) pulmonary arterial hypertension, 43 (7.3%) pulmonary hypertension, and 48 (12.3%) interstitial lung disease. In multivariate analyses, elevated levels of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were associated with increased risk of death, while elevated levels of N-terminal pro b-type natriuretic peptide and C-reactive protein were associated with increased risk of developing pulmonary hypertension. Conclusion: In systemic sclerosis, N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein have independent predictive value for death and pulmonary hypertension. A larger study would be required to determine the predictive value of these biomarkers for less common systemic sclerosis outcomes.

ObjectiveWe sought to explore the prevalence and immediate clinical implications of acute myocardial injury in a cohort of patients with COVID-19 in a region of China where medical resources are less stressed than in Wuhan (the epicentre of the pandemic).MethodsWe prospectively assessed the medical records, laboratory results, chest CT images and use of medication in a cohort of patients presenting to two designated covid-19 treatment centres in Sichuan, China. Outcomes of interest included death, admission to an intensive care unit (ICU), need for mechanical ventilation, treatment with vasoactive agents and classification of disease severity. Acute myocardial injury was defined by a value of high-sensitivity troponin T (hs-TnT) greater than the normal upper limit.ResultsA total of 101 cases were enrolled from January to 10 March 2020 (average age 49 years, IQR 34–62 years). Acute myocardial injury was present in 15.8% of patients, nearly half of whom had a hs-TnT value fivefold greater than the normal upper limit. Patients with acute myocardial injury were older, with a higher prevalence of pre-existing cardiovascular disease and more likely to require ICU admission (62.5% vs 24.7%, p=0.003), mechanical ventilation (43.5% vs 4.7%, p<0.001) and treatment with vasoactive agents (31.2% vs 0%, p<0.001). Log hs-TnT was associated with disease severity (OR 6.63, 95% CI 2.24 to 19.65), and all of the three deaths occurred in patients with acute myocardial injury.ConclusionAcute myocardial injury is common in patients with COVID-19 and is associated with adverse prognosis.

Background: Serial increases in high-sensitivity cardiac troponin (hs-cTnT) have been associated with death in community-dwelling adults, but the association remains uninvestigated in those with coronary artery disease (CAD). Methods: We measured hs-cTnT at baseline and after 5 years in 635 ambulatory Heart and Soul Study patients with CAD. We also performed echocardiography at rest and after treadmill exercise at baseline and after 5 years. Participants were subsequently followed for the outcome of death. We used a multivariable-adjusted Cox proportional hazards model to evaluate the association between 5-year change in hs-cTnT and subsequent all-cause mortality. Results: Of the 635 subjects, there were 386 participants (61%) who had an increase in hs-cTnT levels between baseline and year 5 measurements (median increase 5.6 pg/mL, IQR 3.2–9.9 pg/mL). There were 182 deaths after a mean 4.2-year follow-up after the year 5 visit. After adjusting for clinical variables, a >50% increase in hs-cTnT between baseline and year 5 was associated with a nearly 2-fold increased risk of death from any cause (hazard ratio 1.7, 95% confidence interval 1.1–2.7). When addition of year 5 hs-cTnT was compared to a model including clinical variables and baseline hs-cTnT, there was a modest but statistically significant increase in C-statistic from 0.82 to 0.83 (p = 0.04). Conclusion: In ambulatory patients with CAD, serial increases in hs-cTnT over time are associated with an increased risk of death.

Abstract Background It has been reported that coronary artery disease (CAD) is characterized by inflammation and non-obstructive CAD (NOCAD) increases the risk of cardiovascular events (CVEs) compared with ones with normal or near-normal coronary arteries (NNCA), even is similar to obstructive CAD (OCAD). We hypothesized that elevated high-sensitivity C-reactive protein (hs-CRP) may be linked to CVEs in those patients with NOCAD. Purpose To investigate the predictive role of hs-CRP in patients with NOCAD. Methods Of 7,746 consecutive patients with angina-like chest pain admissions, 4,662 eligible patients were enrolled who received coronary artery angiography (CAG) and followed up for the CVEs comprising all-cause mortality, myocardial infarction, stroke and late revascularization. According to the results of CAG, the patients were classified as NNCA group (<20% stenosis, n=698, 15.0%), NOCAD group (20–49% stenosis, n=639, 14.3%), and OCAD group (≥50% stenosis, n=3325, 70.7%). They were further subdivided into 3 groups according to baseline hs-CRP levels (<1, 1–3 and >3 mg/L). Proportional hazards models were used to assess the risk of CVEs in all patients enrolled. Results A total of 338 patients (7.3%) experienced CVEs during an average of 13403 person-years follow-up. Patients with NOCAD and OCAD had higher rates of CVEs compared to those with NNCA (p<0.05, respectively). In Cox's models after adjustment of confounders, the risk of CVEs elevated with the increasing degrees of CAD with hazard ratio of 2.01 [95% confidence interval (95% CI): 1.07–3.79, p=0.03] for patients with NOCAD and 2.81 (95% CI: 1.60–4.93, p<0.001) for patients with OCAD compared with the NNCA group. Moreover, elevated hs-CRP levels were associated with the severity of coronary lesions and an elevated increased risk of CVEs in patients with NOCAD and OCAD compared those with NNCA (p<0.05, respectively). Conclusions Patients with NOCAD had indeed worse outcomes and hs-CRP levels were positively in relation to the CVEs in those with NOCAD, which may help to the risk assessment in ones with NOCAD.

Mutation Carriers

Mutations in the lamin A/C gene are variably phenotypically expressed; however, it is unclear whether circulating cardiac biomarkers are helpful in the detection and risk assessment of cardiolaminopathies. We sought to assess (1) clinical characteristics including serum biomarkers: high sensitivity troponin T (hsTnT) and N-terminal prohormone brain natriuretic peptide (NT-proBNP) in clinically stable cardiolaminopathy patients, and (2) outcome among pathogenic/likely pathogenic lamin A/C gene (LMNA) mutation carriers. Our single-centre cohort included 53 patients from 21 families. Clinical, laboratory, follow-up data were analysed. Median follow-up was 1522 days. The earliest abnormality, emerging in the second and third decades of life, was elevated hsTnT (in 12% and in 27% of patients, respectively), followed by the presence of atrioventricular block, heart failure, and malignant ventricular arrhythmia (MVA). In patients with missense vs. other mutations, we found no difference in MVA occurrence and, surprisingly, worse transplant-free survival. Increased levels of both hsTnT and NT-proBNP were strongly associated with MVA occurrence (HR > 13, p ≤ 0.02 in both) in univariable analysis. In multivariable analysis, NT-proBNP level > 150 pg/mL was the only independent indicator of MVA. We conclude that assessment of circulating cardiac biomarkers may help in the detection and risk assessment of cardiolaminopathies.
