ABSTRACT
BACKGROUND: Coronary care units are sophisticated clinics established to reduce deaths due to acute cardiovascular events. Current data on coronary care unit mortality rates and predictors of mortality in Turkey are very limited. The MORtality predictors in CORonary care units in TURKey (MORCOR-TURK) trial was designed to provide information on the mortality rates and predictors in patients followed in coronary care units in Turkey. METHODS: The MORCOR-TURK trial will be a national, observational, multicenter, and noninterventional study conducted in Turkey. The study population will include coronary care unit patients from 50 centers selected from all regions in Turkey. All consecutive patients admitted to coronary care units with cardiovascular diagnoses between 1 and 30 September 2022 will be prospectively enrolled. All data will be collected at one point in time, and the current clinical practice will be evaluated (ClinicalTrials.gov number NCT05296694). In the first step of the study, admission diagnoses, demographic characteristics, basic clinical and laboratory data, and in-hospital management will be assessed. At the end of the first step, the predictors and rates of in-hospital mortality will be documented. The second step will be in cohort design, and discharged patients will be followed up till 1 year. Predictors of short- and long-term mortality will be assessed. Moreover, a new coronary care unit mortality score will be generated with data acquired from this cohort. RESULTS: The short-term outcomes of the study are planned to be shared by early 2023. CONCLUSION: The MORCOR-TURK trial will be the largest and most comprehensive study in Turkey evaluating the rates and predictors of in-hospital mortality of patients admitted to coronary care units.

OBJECTIVE: Acute coronary syndrome (ACS) is one of the leading causes of mortality, globally. Atherosclerosis is an underlying factor in ACS process and coagulative cascade is activated secondary to atherosclerotic plaque rupture. Fibrinopeptide A (FPA) takes an active role in thrombus formation and is an indicator of coagulative process. We aimed to evaluate serum FPA level in patients with ACS. METHODS: Patients diagnosed with ACS and chronic coronary syndrome (CCS), with non-obstructive coronary artery disease as a control group, were included in the study. Blood samples and demographic data of all patients were obtained at admission. Obtained data were compared between ACS and control groups. RESULTS: The study consisted of 107 patients with ACS and 69 patients with CCS. ACS group was older (p<0.001) with male preponderance (p<0.001), more likely to had hypertension (p<0.001), and had a higher smoking rate (p<0.001). Serum FPA level was highest in the ST elevated myocardial infarction group (p<0.001). FPA>3.38 ng/mL predicted ACS with 89.7% sensitivity and 78% specificity (AUC: 0.825, 95% CI 0.745-0.905; p<0.001). CONCLUSION: Serum FPA may be used for the differential diagnosis of ACS. In addition, patients with increased FPA may be considered to be given more aggressive antithrombotic medication.
ABSTRACT
Aim The objectives of this study were to determine the relationship between the systemic immune-inflammation index (SII) and new onset atrial fibrillation (NOAF) in patients with acute coronary syndrome (ACS), and to assess the use of this relation, if any, to predict NOAF in the context of ACSMaterial and Methods A total of 622 patients diagnosed with ACS and followed up between September 2019 and September 2021 were included in this study. 35 (5.6â%) of these patients, suffering from NOAF, were designated as the patient group, and the remaining 577 (94.4â%) patients were designated as the control group. SII was calculated with the formula [ (platelet count x neutrophil count)â/âlymphocyte count] in all patients.Results SII was significantly increased in the NOAF group [1641 (778-4506) vs. 660 (54-2835); p<0.001. The multivariable logistic regression analysis revealed that SII [OR: 1.002, 95â%CI: 1.001-1.002, p<0.001] is one of the independent predictors for NOAF, in addition to age (p=0.003) and left atrium size (p=0.005).Conclusion The SII index is an independent predictor of NOAF in ACS patients. This index can be used as an easily accessible value in the clinic. Assessment of risk factors for NOAF may permit early treatment and close follow-up of patients with poor prognosis who may develop AF.

BACKGROUND: Blunted nocturnal blood pressure (BP) reduction, referred to as non-dipper hypertension, is a strong predictor of cardiovascular morbidity and mortality. OBJECTIVES: This study aimed to investigate the relationship between non-dipper hypertension and the severity and complexity of coronary artery disease using SYNTAX score in hospitalized patients with acute coronary syndrome. METHODS: A total of 306 consecutive patients with acute coronary syndrome were screened. Patients who were clinically stable and admitted to the intermediate intensive care unit at least 24 hours after angiography and/or successful revascularization. After the exclusion criteria, 141 patients (34 female and 107 male; mean age 61 ± 11 years) were included. Non-dipper hypertension has been defined as a 0% to 10% decrease in average systolic BP at nighttime compared to daytime, measured at hourly intervals using the same automatic BP measuring device on bedside monitors (Vismo PVM-2701; Nihon Kohden Corp., Tokyo, Japan). SYNTAX score was calculated with an online calculator. The independent predictors of SYNTAX score were assessed using multivariable logistic regression analysis. P < 0.05 was considered statistically significant. RESULTS: The patients with non-dipper hypertension had higher SYNTAX score than the patients with dipper hypertension (11.12 ± 6.41 versus 6.74 ± 6.45, p < 0.0001). In a multivariable logistic regression model, non-dipper hypertension status (odds ratio: 5.159; 95% confidence interval: 2.246 to 11.852, p < 0.001), sex (p = 0.012) and low-density lipoprotein cholesterol (p = 0.008) emerged as independent predictors of high SYNTAX score. CONCLUSIONS: The results of our study provide a possible additional mechanism linking abnormal circadian BP profile with coronary artery disease severity and complexity in patients with acute coronary syndrome.
FUNDAMENTO: Menor redução da pressão arterial (PA) noturna, conhecida como hipertensão não-dipper, é um forte preditor de morbimortalidade cardiovascular. OBJETIVOS: Este estudo visou investigar a relação entre a hipertensão não-dipper e a gravidade e complexidade da doença arterial coronariana usando o escore SYNTAX em pacientes hospitalizados com síndrome coronariana aguda. MÉTODOS: Foram selecionados 306 pacientes consecutivos com síndrome coronariana aguda. Pacientes clinicamente estáveis internados na unidade de terapia intensiva intermediária pelo menos 24 horas após a angiografia e/ou revascularização bem sucedida. Após os critérios de exclusão, foram incluídos 141 pacientes (34 mulheres e 107 homens; idade média 61 ± 11 anos). A hipertensão não-dipper foi definida como uma queda de 0% a 10% na PA sistólica média durante a noite em comparação com o dia, medida em intervalos de 1 hora, usando o mesmo dispositivo automático de medição de PA em monitores de beira de leito (Vismo PVM-2701; Nihon Kohden Corp., Tóquio, Japão). O escore SYNTAX foi calculado com uma calculadora online. Os preditores independentes do escore SYNTAX foram avaliados por meio de análise de regressão logística multivariada. P < 0,05 foi considerado estatisticamente significativo. RESULTADOS: Os pacientes com hipertensão não-dipper apresentaram escore SYNTAX maior do que os pacientes com hipertensão dipper (11,12 ± 6,41 versus 6,74 ± 6,45, p < 0,0001). Em um modelo de regressão logística multivariável, o status de hipertensão não dipper (odds ratio: 5,159; intervalo de confiança de 95%: 2,246 a 11,852, p < 0,001), sexo (p = 0,012) e colesterol de lipoproteína de baixa densidade (p = 0,008) emergiram como preditores independentes de alto escore SYNTAX. CONCLUSÕES: Os resultados do nosso estudo fornecem um possível mecanismo adicional ligando o perfil anormal da PA circadiana à gravidade e à complexidade da doença arterial coronariana em pacientes com síndrome coronariana aguda.

ABSTRACT
The most common cause of complete atrioventricular block (CAVB) is age-related fibrotic degeneration and is referred to as primary idiopathic complete atrioventricular block (iCAVB). This study aims to investigate the relationship between iCAVB and arterial stiffness using the cardio-ankle vascular index (CAVI).In this study, of 205 CAVB patients, 41 patients with iCAVB implanted with a dual-chamber permanent pacemaker and 40 age- and gender-matched controls were studied. Arterial stiffness was assessed by a VaSera VS-1000 CAVI instrument. The CAVI values of patients with iCAVB were significantly higher compared with the controls (9.63 ± 1.42 vs 8.57 ± 1.12, P < .001). Idiopathic complete atrioventricular block frequency was higher among patients with abnormal CAVI values than those with borderline and normal CAVI (P = .04). In multivariate analysis, only CAVI was an independent predictor of iCAVB after adjusting for other relevant factors (odds ratio, 2.575; 95% CI [1.390-4.770]; P = .003). The present study demonstrated that CAVI, as a marker of arterial stiffness, was increased among elderly patients with iCAVB. Thus, we provide a possible additional mechanism linking easily measured CAVI with iCAVB.

We investigated the relationship between peripheral artery disease complexity and coronary artery disease complexity in patients with peripheral artery disease. A total of 449 patients were enrolled. SYNTAX score, a marker of coronary artery disease complexity, was assessed by dedicated computer software and complexity of peripheral artery disease was determined by Trans Atlantic Inter-Society Consensus II classification. The SYNTAX score of patients with minimal peripheral artery disease, Trans Atlantic Inter-Society Consensus A, Trans Atlantic Inter-Society Consensus B, Trans Atlantic Inter-Society Consensus C and Trans Atlantic Inter-Society Consensus D were 5 (11), 12.5 (13.25), 20 (14), 20.5 (19) and 27.5 (19), respectively (values in brackets represent the interquartile range). SYNTAX score and Trans Atlantic Inter-Society Consensus class was moderately correlated (r = 0.495, p < 0.001). In multivariate regression analysis male sex (B = 0.169, p < 0.001, CI95% = 0.270-0.735), Log10 SYNTAX score (B = 0.282, p < 0.001, CI95% = 0.431-0.782), Log10 creatinine (B = 0.081, p = 0.036, CI95% = 0.043-1.239), low-density lipoprotein (B = 0.114, p = 0.003, CI95% = 0.001-0.006) and high-density lipoprotein (B = -0.360, p < 0.001, CI95% = -0.063 to -0.041) were the independent predictors of Trans Atlantic Inter-Society Consensus II class. We have shown that patients with complex peripheral artery disease had complex coronary artery disease.
