Objectives: This meta-analysis aims to investigate the role of high sensitivity-cardiac troponin I (hs-cTnI) as a prognostic factor for cardiac injury and as a risk factor of death for patients with coronavirus disease 2019 (COVID-19). This meta-analysis studies the impact of hs-cTnI elevated levels on C-reactive protein (C-RP) protein, interleukin-6 (IL-6), and D-dimer (DD) levels in COVID-19 affected individuals. Methods: Of 557 downloaded articles according to chosen criteria for this meta-analysis, 11 were finally chosen as they met the criteria. Results: Male and elderly individuals were noticeably prone to COVID-19 infection and considerably underwent death in comparison with female and young individuals. Levels of hs-cTn I, C-RP, IL-6, and DD were significantly higher among dead compare to survivors for COVID-19 affected individuals. Conclusions: Levels of C-RP, IL-6, and DD were considerably high and in linear relation with elevated hs-cTn I levels. Hs-cTn I can be considered a reliable marker for COVID-19 infection prognosis and potent predictor of decease.

Background: The majority of sudden cardiac deaths (SCDs) occur in low-risk populations often as the first manifestation of cardiovascular disease (CVD). Biomarkers are screening tools that may identify subclinical cardiovascular disease and those at elevated risk for SCD. We aimed to determine whether the total to high-density lipoprotein cholesterol ratio, high-sensitivity cardiac troponin I, NT-proBNP (N-terminal pro-B-type natriuretic peptide), or high-sensitivity C-reactive protein individually or in combination could identify individuals at higher SCD risk in large, free-living populations with and without cardiovascular disease. Methods: We performed a nested case-control study within 6 prospective cohort studies using 565 SCD cases matched to 1090 controls (1:2) by age, sex, ethnicity, smoking status, and presence of cardiovascular disease. Results: The median study follow-up time until SCD was 11.3 years. When examined as quartiles or continuous variables in conditional logistic regression models, each of the biomarkers was significantly and independently associated with SCD risk after mutually controlling for cardiac risk factors and other biomarkers. The mutually adjusted odds ratios for the top compared with the bottom quartile were 1.90 (95% CI, 1.30–2.76) for total to high-density lipoprotein cholesterol ratio, 2.59 (95% CI, 1.76–3.83) for high-sensitivity cardiac troponin I, 1.65 (95% CI, 1.12–2.44) for NT-proBNP, and 1.65 (95% CI, 1.13–2.41) for high-sensitivity C-reactive protein. A biomarker score that awarded 1 point when the concentration of any of those 4 biomarkers was in the top quartile (score range, 0–4) was strongly associated with SCD, with an adjusted odds ratio of 1.56 (95% CI, 1.37–1.77) per 1-unit increase in the score. Conclusions: Widely available measures of lipids, subclinical myocardial injury, myocardial strain, and vascular inflammation show significant independent associations with SCD risk in apparently low-risk populations. In combination, these measures may have utility to identify individuals at risk for SCD.

Detection Of Biomarkers

ABSTRACTC-reactive protein (CRP) and cardiac troponin I (cTnI) biomolecules represent the earliest enzymes that appear in the blood when a cardiac injury occurs. Real-time and selective detection of these biomarkers is essential for the prediction and detection of cardiovascular diseases at an early stage. Here we report on the label-free specific detection of both proteins at picomolar concentrations using fabricated nanowire-based biosensors. We demonstrate a novel functionalization technique based on the attachment of dibenzocyclooctyne (DBCO)-linked troponin-specific aptamers to azide-functionalized silicon (Si) nanowire (NW) surface. Due to the fast and reliable immobilization of cTnI-specific aptamers and CRP-specific antibodies on the Si NWs, the fabricated devices can rapidly detect target biomolecules demonstrating high sensitivity. We confirm the attachment of proteins to the surface of Si NWs by atomic force microscopy (AFM). Moreover, we demonstrate that nanowire structures of different sizes enable the detection of biomarkers in a wide concentration range (from 1 pg/ml to 1 µg/ml), corresponding to CRP and cTnI elevation levels during the early stage of disease formation.
