Albus M, Zimmermann T, Median D, Rumora K, Isayeva G, Amrein M, et al.
Eur Heart J Cardiovasc Imaging . 2024 Apr; 25(9):1197-1205. PMID: 38591997
Aims: We aimed to test the hypothesis if combining coronary artery calcium score (Ca-score) as a quantitative anatomical marker of coronary atherosclerosis with high-sensitivity cardiac troponin as a quantitative biochemical...

Wussler D, Belkin M, Maeder M, Walter J, Shrestha S, Kupska K, et al.
Eur J Heart Fail . 2023 Oct; 25(12):2218-2229. PMID: 37871997
Aims: Sex-specific differences in acute heart failure (AHF) are both relevant and underappreciated. Therefore, it is crucial to evaluate the risk/benefit ratio and the implementation of novel AHF therapies in...

Koechlin L, Strebel I, Zimmermann T, Nestelberger T, Walter J, Lopez-Ayala P, et al.
Ann Emerg Med . 2023 Feb; 82(2):194-202. PMID: 36774205
Study Objective: The diagnostic performance of T-wave amplitudes for the detection of myocardial infarction is largely unknown. We aimed to address this knowledge gap. Methods: T-wave amplitudes were automatically measured...

Amrein M, Meier S, Schafer I, Schaedelin S, Willemse E, Benkert P, et al.
Biomarkers . 2023 Jan; 28(3):341-351. PMID: 36714921
Functionally relevant coronary artery disease (fCAD), causing symptoms of myocardial ischemia, can currently only be reliably detected with advanced cardiac imaging. Serum neurofilament light chain (sNfL) is a biomarker for...

Williams S, Ostroff R, Hinterberg M, Coresh J, Ballantyne C, Matsushita K, et al.
Sci Transl Med . 2022 Apr; 14(639):eabj9625. PMID: 35385337
A reliable, individualized, and dynamic surrogate of cardiovascular risk, synoptic for key biologic mechanisms, could shorten the path for drug development, enhance drug cost-effectiveness and improve patient outcomes. We used...

Amrein M, Li X, Walter J, Wang Z, Zimmermann T, Strebel I, et al.
Clin Res Cardiol . 2022 Feb; 111(6):692-704. PMID: 35220448
Background: Trimethylamine N-oxide (TMAO) has been associated with cardiovascular outcomes. However, the diagnostic value of TMAO and its precursors have not been assessed for functionally relevant coronary artery disease (fCAD)...

Lopez-Ayala P, Nestelberger T, Boeddinghaus J, Koechlin L, Ratmann P, Strebel I, et al.
Circulation . 2021 Aug; 144(10):773-787. PMID: 34376064
Background: The non-ST-segment-elevation myocardial infarction (NSTEMI) guidelines of the European Society of Cardiology (ESC) recommend a 3h cardiac troponin determination in patients triaged to the observe-zone of the ESC 0/1h-algorithm;...

Belkin M, Wussler D, Gualandro D, Shrestha S, Strebel I, Goudev A, et al.
ESC Heart Fail . 2021 Aug; 8(5):4218-4227. PMID: 34355538
Aims: We aimed to assess the long-term effect of a strategy of comprehensive vasodilation versus usual care on health-related quality of life (HRQL) among patients with acute heart failure (AHF)....

J Virol . 2021 Apr; 95(14):e0013021. PMID: 33893170
The nasal mucosa constitutes the primary entry site for respiratory viruses, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). While the imbalanced innate immune response of end-stage coronavirus disease 2019...

Wildi K, Boeddinghaus J, Nestelberger T, Haaf P, Koechlin L, Ayala Lopez P, et al.
Clin Biochem . 2021 Feb; 91:16-25. PMID: 33636187
Background: Combining high-sensitivity cardiac troponin (hs-cTn) with estimated glomerular filtration rate and glucose within the Clinical Chemistry Score (CCS) could help in the assessment of patients with suspected acute myocardial...
