    C-reactive protein to albumin ratio predicts for severity of coronary artery disease and ischemia
    (Verduci Publisher, 2022) Sabanoglu, C.; Inanc, I. H.
    OBJECTIVE: Myocardial perfu-sion scintigraphy (MPS) has prognostic importance in demonstrating myocardial ischemia, and the Syntax score (SS) in coronary angiogra-phy has prognostic importance in demonstrat-ing the extent of coronary artery disease (CAD). C-reactive protein (CRP) and albumin are prognostic markers for both atherosclerosis and inflammation. In this study, we aimed at investigating the relationship of CRP/albumin ratio (CAR) with the severity of myocardial ischemia and SS in patients with stable CAD. PATIENTS AND METHODS: We retrospec-tively evaluated 355 patients between January 2018 and January 2020. Patients were divided into normal, mild-moderate, and severe ischemia groups according to MPS. SS was classi-fied as low risk (< 32) and high risk (>= 32) groups. The association between CAR, SS, and MPS findings were analyzed. RESULTS: The median CAR level was high-er in the high-risk group compared to the low -risk group (20.7 vs. 13.8, p < 0.05), and higher in the low-risk group compared to the normal group (13.8 vs. 7.4, p < 0.05). The increase in CAR level was associated with increased ischemia severity (p < 0.001). Increased CAR level was found to be an independent predictor of both high-risk and severe ischemia (OR = 1.04, p = 0.006; OR = 1.05, p = 0.001, respectively). The cut-off value of CAR > 10.2 was a common point in predicting both low -risk and mild-moderate ischemia (AUC: 0.736, p < 0.001; AUC: 0.741, p < 0.001, respectively). CONCLUSIONS: High CAR level was an inde-pendent predictor of both the severity of ischemia and the extent of CAD. Therefore, CAR can be a potential screening tool in patients with suspected CAD and in risk stratification.

    Long-term predictive value of cardiac biomarkers in patients with COVID-19 infection
    (Verduci Publisher, 2022) Sabanoglu, C.; Inanc, I. H.; Polat, E.; Peker, S. A.
    OBJECTIVE: Several studies have investigated the association between cardiac biomarkers and short-term prognosis in the COVID-19 infection. However, the data on the pre-dictive value of cardiac biomarkers to predict long-term prognosis in COVID-19 infection are limited. We aimed at determining the relationship between N-terminal brain-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin I (hs-TnI) as cardiac biomarkers and in-hospital/ long-term outcomes in COVID-19 infection.PATIENTS AND METHODS: The study included a total of 916 patients with confirmed COVID-19 infection. The primary outcome was in-hospital and 1-year mortality. The secondary outcome was intensive care need at admission or the need to be transferred to the intensive care unit later on.RESULTS: The study included 498 (54.4%) males and 418 (45.6%) females with a mean age of 55.1 & PLUSMN;18.5 years. The patients with known heart failure (HF), COVID-19-related HF, acute renal failure (ARF), chronic kidney disease (CKD), diabetes mellitus, hypertension, coronary artery dis-ease (CAD), chronic obstructive pulmonary dis-ease (COPD)/asthma, high CO-RADS score (& GE; 4), lower EF, higher hs-TnI, and NT-proBNP levels had increased in-hospital and 1-year mortality. After multivariate analysis, NT-proBNP, hs-TnI, CKD, ARF, diabetes mellitus, and CAD were independent predictors of in-hospital and 1-year mortali-ty. After ROC analysis, NT-proBNP cut-off levels of 1022.50 (sensitivity 87.5%, specificity 87.1%) and 1008 (sensitivity 88.6%, specificity 88.0%) were found to predict in-hospital and 1-year mortality, respectively. Hs-TnI cut-off levels of 49.6 (sensitivity 88.6%, specificity 88.9%) and 34.10 (sensitivity 83.8%, specificity 84.1%) were found to predict in-hospital and 1-year mortality, respectively.CONCLUSIONS: The current study suggests that NT-proBNP and hs-TnI can be used as valuable cardiac biomarkers to predict short-term and long-term parameters in COVID-19 infection.

    The relationship of masked hypertension with autonomic dysfunction and cardiometabolic parameters: a case-control study
    (Verduci Publisher, 2022) Inanc, I. H.; Sabanoglu, C.
    OBJECTIVE: Masked hypertension (MH) is associated with cardiovascular events and mortality. Data on the association between exaggerated blood pressure response (EBPR) to exercise, heart rate recovery (HRR), which are indicators of autonomic dysfunction, and MH are lacking. This study aimed at evaluating the association between EBPR, HRR, and MH. PATIENTS AND METHODS: Between January 2020 and January 2021, 130 MH (57 male, median age = 52.8 years) and 60 healthy (28 male, median age = 40.8 years) subjects were included in this single-center, case-control, and cross-sectional study. Office blood pressure measurement, 24-hour ambulatory blood pressure monitoring, treadmill test, echocardiography, and specific biochemical parameters were evaluated. RESULTS: The frequency of blunted HRR (73 subjects, 56.2%) and EBPR (40 subjects, 30.8%) were significantly higher in patients with MH (p < 0.001). Patients with MH had higher serum uric acid levels and frequency of hyperlipidemia (p < 0.05). Diameters of the left atrium (LA), aortic root, and ascending aorta were significantly higher in MH patients (p < 0.05). Thirty-two (24.6%) patients with MH had left ventricular hypertrophy and 33 (25.4%) had diastolic dysfunction (p < 0.001). Multivariate analysis identified the presence of blunted HRR as an independent predictor factor of MH as well as smoking, hyperlipidemia, GFR, LA diameter, and aortic root diameter were other independent factors. CONCLUSIONS: The frequency of blunted HRR and EBPR were significantly higher in the MH group compared to the control group, suggesting a close relationship between MH and autonomic dysfunction.
