The Prognostic Value of Bendopnea In-Hospital Mortality In Patients With Acute Coronary Syndrome

Öz

Background: Bendopnea, also known as flexi-dyspnea, has recently been defined as the development of shortness of breath within 30 seconds by bending forward in patients with systolic and decompensated heart failure. There is no clear data in the literature regarding acute coronary syndrome (ACS) patients and in-hos-pital mortality. This study investigated the effect of the presence of bendopnea on in-hospital mortality in ACS patients. Materials and Methods: A cross-sectional analysis was conducted on patients admitted with ACS (unstable angina and non-ST elevation myocardial infarction (NSTEMI)) between March 2023 and January 2024. The presence of orthopnea, bendopnea, paroxysmal nocturnal dyspnea PND and venous jugular distention (VJD) recorded. Coronary angiography was performed in all patients. A total of 395 patients were enrolled in this study. Results: The patients were divided into 2 groups as living and deceased. The deceased group was significantly older. Bendopnea, PND, and orthopnea were statistically higher in the deceased group. left ventricular ejec-tion fraction(LVEF) was statistically lower, syntax score was statistically higher in the deceased group. Age (%95 CI:1.254-1.627 , OR: 1.411 p:0.001), uric acid (%95 CI: 1.151-1.394 OR: 1.278 p:0.001), bendopnea (%95 CI: 1.285-1.611 OR: 1.452 p: 0.001), syntax score (%95 CI: 1.103-1.358 OR: 1.258 p:0.001) were shown to be independent risk factors for mortality. Conclusions: The presence of bendopnea in patients with ACS may be closely associated with in-hospital mor-tality.

Bendopnenin Akut Koroner Sendromlu Hastalarda Hastane İçi Mortalitesindeki Öngördürücü Değeri

Öz

Amaç: Flexi-dispne olarak da bilinen bendopne, son zamanlarda sistolik ve dekompanse kalp yetmezliği olan hastalarda öne doğru eğilerek 30 saniye içinde nefes darlığı gelişmesi olarak tanımlanmıştır. Bu çalışmada AKS hastalarında bendopne varlığının hastane içi mortalite üzerine etkisi araştırıldı. Materyal ve Metod: Mart 2023 ile Ocak 2024 arasında AKS (kararsız anjina ve ST yükselmesiz miyokard en-farktüsü (NSTEMI)) ile başvuran hastalar üzerinde kesitsel bir analiz yapıldı. Bendopne varlığı kaydedildi. Tüm hastalara koroner anjiyografi yapıldı. Bu çalışmaya toplam 395 hasta dahil edildi. Bulgular: Hastalar yaşayanlar ve ölenler olarak 2 gruba ayrıldı. Ölen grup istatististiksel olarak daha yaşlıydı. Bendopne, paroksismal nokturnal dispne (PND) ve ortopne, ölen grupta istatistiksel olarak daha yüksekti. Ölen grupta sol ventrikül ejeksiyon fraksiyonu istatistiksel olarak daha düşük, syntax skoru ise istatistiksel olarak daha yüksekti. Yaş ((%95 CI:1.254-1.627 , OR: 1.411 p:0.001), ürik asit (%95 CI: 1.151-1.394 OR: 1.278 p:0.001), bendopne (%95 CI: 1.285-1.611 OR: 1.452 p: 0.001), syntax skoru ((%95 CI: 1.103-1.358 OR: 1.258 p:0.001), mortalite için bağımsız risk faktörleri olduğu gösterilmiştir. Sonuç: AKS'li hastalarda bendopnenin varlığı hastane içi mortalite ile yakından ilişkili olabilir
