Abstract

Background

COVID-19 has been associated with a high prevalence of myocardial injury and increased cardiovascular morbidity. Copeptin, a marker of vasopressin release, has been previously established as a risk marker in both infectious and cardiovascular disease.

Methods

This prospective, observational study of patients with laboratory-confirmed COVID-19 infection was conducted from June 6th to November 26th, 2020 in a tertiary care hospital. Copeptin and high-sensitive cardiac troponin I (hs-cTnI) levels on admission were collected and tested for their association with the primary composite endpoint of ICU admission or 28-day mortality.

Results

A total of 213 eligible patients with COVID-19 were included of whom 55 (25.8%) reached the primary endpoint. Median levels of copeptin and hs-cTnI at admission were significantly higher in patients with an adverse outcome (Copeptin 29.6 pmol/L, [IQR, 16.2–77.8] vs 17.2 pmol/L [IQR, 7.4–41.0] and hs-cTnI 22.8 ng/L [IQR, 11.5–97.5] vs 10.2 ng/L [5.5–23.1], P < 0.001 respectively). ROC analysis demonstrated an optimal cut-off of 19.3 pmol/L for copeptin and 16.8 ng/L for hs-cTnI and an increase of either biomarker was significantly associated with the primary endpoint. The combination of raised hs-cTnI and copeptin yielded a superior prognostic value to individual measurement of biomarkers and was a strong prognostic marker upon multivariable logistic regression analysis (OR 4.274 [95% CI, 1.995–9.154], P < 0.001). Addition of copeptin and hs-cTnI to established risk models improved C-statistics and net reclassification indices.

Conclusion

The combination of raised copeptin and hs-cTnI upon admission is an independent predictor of ICU admission or 28-day mortality in hospitalized patients with COVID-19.

VHF-Ablation nützt wohl nur bei reduzierter Auswurfleistung

02.05.2024 Ablationstherapie Nachrichten

Ob die Katheterablation von Vorhofflimmern bei Patienten mit Herzinsuffizienz die Komplikationsraten senkt, scheint davon abzuhängen, ob die Auswurfleistung erhalten ist oder nicht. Das legen die Ergebnisse einer Metaanalyse nahe.

Das Risiko für Vorhofflimmern in der Bevölkerung steigt

02.05.2024 Vorhofflimmern Nachrichten

Das Risiko, im Lauf des Lebens an Vorhofflimmern zu erkranken, ist in den vergangenen 20 Jahren gestiegen: Laut dänischen Zahlen wird es drei von zehn Personen treffen. Das hat Folgen weit über die Schlaganfallgefährdung hinaus.

Weniger Extremitätenischämien mit dualer Plättchenhemmung

02.05.2024 Thrombozytenaggregationshemmer Nachrichten

Eine Behandlung mit Ticagrelor zusätzlich zu ASS kann das Risiko für Revaskularisierungen und Amputationen von Extremitäten bei Diabetikern mit stabiler KHK deutlich reduzieren, vor allem für solche mit PAVK. Dafür spricht eine Auswertung der Interventionsstudie THEMIS.

Beutel versus Maschine: Beste Beatmungstechnik bei Herzstillstand gesucht

Stehen die Chancen auf eine Rückkehr der Spontanzirkulation nach Herz-Kreislauf-Stillstand bei manueller oder maschineller Beatmung besser? Und unterscheidet sich das neurologische Outcome nach der Reanimation? Das belgische Herzstillstand-Register liefert die Daten für einen direkten Vergleich zwischen Beutel und Beatmungsgerät.
