Resumo Fundamento: A isquemia com artéria coronária não obstrutiva (INOCA) é uma doença cardíaca isquêmica que inclui principalmente disfunção microvascular coronariana e/ou vasoespasmo coronariano epicárdico devido à disfunção vascular coronariana subjacente e pode ser observada mais comumente em pacientes do sexo feminino. O índice de inflamação imunológica sistêmica (SII, relação plaquetas × neutrófilos/linfócitos) é um novo marcador que prediz resultados clínicos adversos na doença arterial coronariana (DAC). Objetivo: Este estudo tem como objetivo investigar a relação entre INOCA e SII, [...] Resumo Fundamento: A isquemia com artéria coronária não obstrutiva (INOCA) é uma doença cardíaca isquêmica que inclui principalmente disfunção microvascular coronariana e/ou vasoespasmo coronariano epicárdico devido à disfunção vascular coronariana subjacente e pode ser observada mais comumente em pacientes do sexo feminino.

A decrease in the left ventricular ejection fraction (≤40%) in the setting of ST-segment elevation myocardial infarction is a significant predictor of mortality in the young ST-segment elevation myocardial infarction population. In this study, we aimed to investigate the predictors of left ventricular ejection fraction reduction and evaluate the long-term mortality rates in young ST-segment elevation myocardial infarction patients with or without decreased left ventricular ejection fraction. We enrolled retrospectively 411 consecutive ST-segment elevation myocardial infarction patients aged 45 years or below who underwent primary percutaneous coronary intervention. Young ST-segment elevation myocardial infarction patients were divided into two groups according to their left ventricular ejection fraction (≤40%, n=72 and >40%, n=339), which were compared with each other. Statin use, white blood cell count, C-reactive protein, peak creatine kinase-MB, prolonged ischemia time, left anterior descending artery-related infarction, proximally/ostial located lesion, and no-reflow were independently associated with low left ventricular ejection fraction. Additionally, long-term mortality was considerably higher in the left ventricular ejection fraction ≤40% group than those in the left ventricular ejection fraction>40% group (18.1% versus 2.4%; p<0.001). In young ST-segment elevation myocardial infarction patients, lesion properties (left anterior descending lesion, proximally located lesion), no-reflow, and prolonged ischemia time appeared to be important determinants for the left ventricular ejection fraction decline, rather than coronary disease severity or demographic and hematological parameters. Statin use may be preventive in the development of left ventricular ejection fraction decline in young ST-segment elevation myocardial infarction patients.

Objective: In recent years, an increasing number of evidences suggests that inflammation plays a significant role in the pathophysiology of pulmonary embolism. Although the association between inflammatory markers and pulmonary embolism prognosis has been previously reported, no studies have investigated the ability of the C-reactive protein/albumin ratio, defined as an inflammation-based prognostic score, to predict death in patients experiencing a pulmonary embolism. Materials and methods: This retrospective study included 223 patients experiencing a pulmonary embolism. The study population was divided into two groups according to their C-reactive protein/albumin ratio values and analyzed whether the C-reactive protein/albumin ratio was an independent predictor of late-term mortality. Then, the performance of the C-reactive protein/albumin ratio in predicting patients’ outcomes was further compared with its components. Results: Out of 223 patients, death was observed in 57 patients (25.60%) during an average follow-up of 18 months (range: 8–26). The average C-reactive protein/albumin ratio was 0.12 (0.06–0.44). The group with a higher C-reactive protein/albumin ratio was older and had a higher troponin level and simplified Pulmonary Embolism Severity Index score. Independent predictors of late-term mortality were found to be C-reactive protein/albumin ratio (hazard ratio: 1.594, 95% CI: 1.003–2.009; p < 0.001), cardiopulmonary disease, simplified Pulmonary Embolism Severity Index score and fibrinolytic therapy. Receiver operating characteristic curve comparisons for both 30-day and late-term mortality demonstrated that the C-reactive protein/albumin ratio was a better predictor than both albumin and C-reactive protein, separately. Conclusion: The present study revealed that the C-reactive protein/albumin ratio is an independent predictor of both 30-day and late-term mortality in patients experiencing a pulmonary embolism. As a marker that can be easily obtained, and calculated, and does not require additional costs C-reactive protein/albumin ratio can be an effective parameter used for prognosis estimation of pulmonary embolism.

By the beginning of this study in 2019, it was known that hypertension is a risk factor for erectile dysfunction, and also, there are circadian changes that occur in blood pressure. Further, non-dipping hypertension is known to be linked to poor cardiac outcomes and erectile functions, so the research described in this article was initiated with an aim to explore the potential relationship between erectile dysfunction and circadian patterns of newly diagnosed hypertension. Between April 2019 and May 2022, 583 patients aged 30-70 years were diagnosed with erectile dysfunction (ED) in our outpatient clinic. Applying our exclusion criteria to 583 patients, a group of 371 patients left with us; these patients were referred to the cardiology clinic for hypertension evaluation with consecutive ambulatory blood pressure monitoring (ABPM). Data were collected for the study prospectively. Of the 371 patients evaluated with ABPM, 125 had newly diagnosed hypertension (mean BP ≥135/85 mmHg in ABPM). These patients were divided into two groups according to the pattern of hypertension identified in ABPM: dippers (Group D) and non-dippers (Group ND). They were then compared using clinical and laboratory findings, including erectile function scores. While the number of patients in the ND group was 83, the number in the D group was 42. In the ND group, the mean age was higher (59 ± 10 vs. 54 ± 12, p = 0.0024). IIEF-5 (international index of erectile function) scores were determined to be significantly lower in the ND group (14.4 ± 4.9 vs. 11.5 ± 4.6, p = 0.001). Also, serum creatinine levels were higher in Group ND than in D (0.96 ± 0.12 vs. 1 ± 0.15, p = 0.001). In our multivariate analysis, IIEF-5 scores (OR: 0.880, 95% CI: 0.811-0.955; p = 0.002) and serum creatinine levels (OR: 1027, 95% CI: 1003-1052; p = 0.025) were found to be independent risk factors of non-dipper HT. The cut-off value of the IIEF-5 score for non-dipper HT in a ROC curve analysis was 13.5 with 64.3% sensitivity and 66.1% specificity (area under curve value: 0.673 [95% CI: 0.573-0.772, p < 0.001]). This study showed that, in patients with ED, the non-dipper pattern was associated with poorer erectile function when HT was newly diagnosed. We also found that the severity of erectile dysfunction is an independent marker for non-dipper HT.

We aimed to investigate the association between the HALP score and in-hospital mortality in patients with non-ST segment myocardial infarction (NSTEMI). In this retrospective study participants were divided into two groups, based on the median HALP score. Findings were compared between the groups. A total of 1648 patients included. The median HALP score cutoff value was 3.87. While the low HALP score group (3.87) included 824 patients. Patients with the low HALP score were older and had a higher prevalence of comorbidities. A HALP score ≤ 2.62 predicted in-hospital mortality with sensitivity of 72.5% and a specificity of 77.3% (area under curve 0.809), according to ROC curve analysis. In multivariate analysis, age, diastolic blood pressure, Killip Class > 1 and Syntax Score, creatinine level, LVEF and HALP Score (OR: 0.504, 95% CI: 0.415-0.613; p < 0.001) were independently associated with in-hospital mortality. According to the current study, the HALP score was independently associated with in-hospital mortality in patients with NSTEMI. Moreover, HALP score might be used as a predictor of in-hospital mortality in this population.
