The Evaluation of Chronotropic Incompetence and Cardiac Functions in Patients Recovered from Covid-19 Disease

Abstract

Objective: Today, coronary bypass surgeries are still commonly performed with on-pump CABG and off-pump CABG techniques. In this retrospective clinical study, we investigated the short- and long-term complications of both surgical methods. Materials and Methods: In this study, patients with isolated single-vessel coronary artery disease according to Syntax scoring in our clinic between 2011 and 2015. A total of 43 patients who underwent on-pump (Group 1) and off-pump (Group 2) coronary artery surgery were included. In these patients, early postoperative complications and one-year major adverse cardiovascular and cerebral events were compared. Results: There were no statistically significant differences in terms of demographic values between the two groups. In terms of postoperative complications, atrial fibrillation was found to be significantly less in the off-pump surgery group. There was no significant difference in terms of length of stay in the intensive care unit and hospital, pneumonia, sternal infection and the amount of postoperative drainage. There was no difference between the groups in terms of major adverse cardiovascular and cerebral events (MACCE) in the long term after the operation. Conclusion: In conclusion, we suggest to determine the method to be applied in coronary bypass surgery according to the patient's risk scoring

Covid-19 Enfeksiyonu Geçirmiş ve İyileşmiş Hastalarda Kronotropik Yetersizliğin ve Kardiyak Fonksiyonların Değerlendirilmesi

Abstract

Giriş ve Amaç: Günümüzde koroner bypass ameliyatları hala yaygın olarak on-pump CABG ve off-pump CABG tekniği ile yapılmaktadır. Bu retrospektif klinik çalışmada her iki cerrahi yöntemin kısa ve uzun dönem komplikasyonlarını araştırdık. Gereç ve Yöntemler: Bu çalışmaya 2011-2015 yılları arasında kliniğimizde Syntax skorlamasına göre izole tek damar koroner arter hastalığı olan; on-pump (Grup 1) ve off-pump (Grup 2) koroner arter cerrahisi geçiren toplam 43 hasta dahil edilmiştir. Bu hastalarda postoperatif erken dönem komplikasyonlar ve bir yıllık majör advers kardiyovasküler ve serebral olaylar karşılaştırılmıştır. Bulgular: Her iki grup arasında demografik verilerde istatistiksel olarak anlamlı fark saptanmadı. Postoperatif komplikasyonlar açısından atrial fibrilasyon off-pump cerrahi yapılan grupta anlamlı olarak daha az saptanmıştır. Yoğun bakımda ve hastanede kalış süreleri, pnömoni, sternal enfeksiyon ve postoperatif drenaj miktarları açısından anlamlı farklılık saptanmamıştır. Operasyon sonrası uzun dönemde majör adverse kardiyovasküler ve serebral olaylar (MACCE) açısından gruplar arasında farklılık saptanmamıştır. Sonuç: Sonuç olarak koroner bypass cerrahisinde uygulanacak yöntemin hastanın risk skorlamasına göre belirlenmesini öneriyoruz.
