    The effect of body mass index on complications in cardiac implantable electronic device surgery
    (WILEY, 2023) Güzel, Tuncay; Demir, Muhammed; Aktan, Adem; Kılıç, Raif; Arslan, Bayram; Günlü, Serhat; Altıntaş, Bernas; Karahan, Mehmet Zülkif; Özbek, Mehmet; Aslan, Burhan; Arpa, Abdulkadir; Coşkun, Mehmet Sait; Altunbaş, Mahsum; Tüzün, Rohat; Akgümüş, Alkame; Karadeniz, Muhammed; Aydın, Saadet; Güzel, Hamdullah; Aslan, Selen Filiz; Söner, Serdar; Taş, Ahmet; Ertaş, Faruk
    Background: Cardiac implantable electronic device (CIED) procedures are prone to complications. In our study, we investigated the effect of body mass index (BMI) on CIED-related complications. Methods: 1676 patients who had undergone CIED surgery (de novo implantation, system upgrade, generator change, pocket revision or lead replacement) at two heart centers in Turkey and met the study criteria were included in our study. For analysis of primary and secondary endpoints, patients were classified as non-obese (BMI < 25 kg/m2), overweight (25 ≤ BMI < 30 kg/m2), and obese (BMI ≥ 30 kg/m2). The primary endpoint was accepted as cumulative events, including the composite ofclinically significant hematoma (CSH), pericardial effusion or tamponade, pneumoth- orax, and infection related to the device system. Secondary outcomes included each component of cumulative events. Results: The rate of cumulative events, defined as primary outcome, was higher in the obese patient group, and we found a significant difference between the groups (3.0%, 4.3%, 8.9%, p = .001). CSH and pneumothorax rates were significantly higher in the obese patient group (0.3%, 0.9%, 1.9%, p = .04; 1.0%, 1.4%, 3.3%, p = .04, respectively). According to our multivariate model analysis; gender (OR:1.882, 95%CI:1.156–3.064, p = .01), hypertension (OR:4.768, 95%CI:2.470–9.204, p < .001), BMI (OR:1.069, 95%CI:1.012–1.129, p = .01) were independent predictors of cumulative events rates. Conclusions: Periprocedural complications associated with CIED (especially hematoma and pneumothorax) are more common in the group with high BMI.

    The predictive effect of shock index on mortality in patients with acute heart failure
    (AME Publishing, 2023) Günlü, Serhat; Kayan, Fethullah; Karahan, Mehmet Zülkif
    Background: The predictive usefulness of the shock index (SI), which is determined as a proportion of heart rate (HR) to systolic blood pressure (SBP), and age-adjusted SI (SI × age) for clinical outcomes other than mortality in acute heart failure (AHF) is not well established. This research aimed to examine whether SI and SI × age measured non-invasively at a patient’s bedside can identify mortality risk in patients admitted to the coronary care unit (CCU) with AHF. Methods: This research was carried out as a retrospective case-control study. Indices were calculated. The receiving operating characteristic (ROC) and Youden index were applied to calculate the optimal SI and SI × age cut-off for estimating mortality. Using multivariate analysis to determine independent indicators of mortality in patients with AHF. Results: A total of 1,468 patients who were hospitalized at the CCU with AHF were included. The population’s median age was 81 (73–91) years and 53.7% were male. In the survivor group, the median SI was 0.6 (0.5–0.75), and the median SI × age was 46 (38–58). In the non-survivor group, the median SI was 0.62 (0.55–0.81) and the median SI × age was 53 (44–66). According to the Youden index, the best value of SI was 0.56 with a specificity of 46% and a sensitivity of 70%, and the best value of SI × age was 44.8 with a specificity of 48% and a sensitivity of 76%. In the multivariate analysis, the power of SI × age to predict mortality was 2.39 times greater than other independent predictors. Conclusions: SI and SI × age calculated in the CCU may be valuable prognostic markers for identifying AHF patients at high risk for adverse outcomes.
