Higher C-Reactive Protein to Albumin Ratio Portends Long-Term Mortality in Patients with Chronic Heart Failure and Reduced Ejection Fraction.

Background and Objectives: In this study, we aimed to investigate the prognostic value of the C-reactive protein to albumin ratio (CAR) for all-cause mortality in patients with chronic heart failure with reduced ejection fraction (HFrEF). Materials and Methods: In total, 404 chronic HFrEF patients were included in this observational and retrospective study. The CAR value of each patient included in this analysis was calculated. We stratified the study population into tertiles (T1, T2, and T3) according to CAR values. The primary outcome of the analysis was to determine all-cause mortality. Results: The median follow-up period in our study was 30 months. In the follow-up, 162 (40%) patients died. The median value of CAR was higher in patients who did not survive during the follow-up [6.7 (IQR = 1.6-20.4) vs. 0.6 (IQR = 0.1-2.6), p < 0.001]. In addition, patients in the T3 tertile (patients with the highest CAR) had a higher rate of all-cause mortality [n = 90 cases (66.2%), p < 0.001]. Multivariate Cox regression analysis revealed that CAR was an independent predictor of mortality in patients with HFrEF (hazard ratio: 1.852, 95% confidence interval: 1.124-2.581, p = 0.005). In a receiver operating characteristic curve analysis, the optimal cut-off value of CAR was >2.78, with a sensitivity of 66.7% and specificity of 76%. Furthermore, older age, elevated N-terminal pro-brain natriuretic peptide levels, and absence of a cardiac device were also independently associated with all-cause death in HFrEF patients after 2.5 years of follow-up. Conclusions: The present study revealed that CAR independently predicts long-term mortality in chronic HFrEF patients. CAR may be used to predict mortality among these patients as a simple and easily obtainable inflammatory marker.

Predictive value of P wave parameters, indices, and a novel electrocardiographic marker for silent cerebral infarction and future cerebrovascular events.

BACKGROUND: Silent cerebral infarction (SCI) is a neuronal injury without a clinically apparent stroke or transient ischaemic attack. Left atrial cardiomyopathy is closely associated with SCI. P wave changes in the electrocardiogram (ECG) provide significant information about the development of atrial cardiomyopathy. This study evaluated the role of P wave parameters and indices and a novel ECG parameter in predicting SCI, future cerebrovascular events, and atrial fibrillation/flutter. MATERIALS AND METHODS: A total of 272 patients were retrospectively screened and divided into two groups according to SCI. Cerebrovascular events and atrial fibrillation/flutter were defined as the study's outcomes. P wave parameters, indices, and a novel ECG parameter called the P wave ratio (PWR) were calculated from ECGs, and the relationship between SCI and outcomes was investigated. RESULTS: The maximum P wave duration (PWD), P wave dispersion (PWdisp), PWD measured from the D2 lead (PWDD2), P wave peak time measured from the D2 lead (PWPTD2), PWPT measured from the V1 lead (PWPTV1), and P wave terminal force (PWTFV1) were significantly longer in the SCI group. Both partial and advanced inter atrial block (IAB) were significantly high in the SCI group. The novel parameter P wave ratio (PWR) was significantly longer in the SCI group (0.55 ± 0.08 vs. 0.46 ± 0.09; p < 0.001). In multivariate regression analysis, PWdisp (OR: 1.101, p < 0.001), PWPTD2 (OR: 1.095, p = 0.017), and PWR (OR: 1.231, p < 0.001) were found to be independent predictors of SCI. Cox regression analysis revealed that the PWR (HR 1.077; 95% CI 1.029-1.128; p = 0.001) was associated with cerebrovascular events and atrial fibrillation/flutter. CONCLUSION: In our study, we observed that PWR could be a valuable parameter for predicting SCI and future cerebrovascular events.

Euglycemic diabetic ketoacidosis associated with ST segment elevation myocardial infarction following SGLT-2 inhibitor therapy.

Sodium-glucose cotransporter-2 (SGLT-2) inhibitors are the latest approved class of oral antidiabetic agents that inhibit renal SGLT-2 receptors and increase urinary glucose excretion in the luminal membrane of the proximal tubule. Diabetic ketoacidosis (DKA) is a triad of hyperglycemia, ketosis, and a high anion gap with metabolic acidosis. We present the case of 61 years-old men with severe euglycemic DKA (EDKA) complicated ST-segment elevation myocardial infarction following SGLT-2 inhibitor therapy for type 2 diabetes mellitus. Atypical presentation of ketoacidosis without hyperglycemia can delay diagnosis and may result in catastrophic complications. Quick diagnosis, appropriate clinical and biochemical assessment, and effective treatment protocols ensure successful resolution of EDKA.

Predictive Value of the Naples Prognostic Score for Acute Kidney Injury in ST-Elevation Myocardial Infarction Patients Undergoing Primary Percutaneous Coronary Intervention.

The purpose of this investigation was to investigate whether there was an association between the Naples prognostic score and the development of acute kidney injury (AKI) in ST-elevation myocardial infarction (STEMI) patients following primary percutaneous coronary intervention (pPCI). The study comprised 2901 consecutive STEMI patients who had pPCI. For each patient, the Naples prognostic score was determined. To evaluate the predictive performance of the Naples score (which included either continuous and categorical variables), we developed a Nested model and a nested model combined with the Naples score. The Naples prognostic score was the most significant predictor of AKI occurrence after admission creatinine, age, and contrast volume. The continuous Naples prognostic score model provided the best prediction performance and discriminative ability. The C-index of the Nested and full models with continuous Naples prognostic score were significantly higher than that of the Nested model. The decision curve analysis found that the overall model had a higher full range of probability of clinical net benefit than the baseline model, with a 10% AKI likelihood. The present study found that the Naples prognostic score may be useful to predict the risk of AKI in STEMI patients undergoing pPCI.

A novel technique to reach the contralateral iliac artery in Leriche syndrome.

BACKGROUND/OBJECTIVE: The endovascular approach is the first choice of treatment in high-risk patients suffering from Leriche syndrome. Although many techniques and devices have been developed, there are still difficulties in accessing the true lumen. Herein, we reported a novel technique to increase the support and ease of crossing the lesion. METHOD: We presented a case report of a 45-year-old male patient with Leriche syndrome. The patient refused surgery; therefore, he was scheduled for endovascular treatment. RESULTS: We attempted to cross the right and left common iliac occlusions by intraluminal crossing. The left common iliac artery couldn't be cannulated despite the stiff wires and percutaneous intentional extraluminal revascularization (PIER). Afterward, a cross-over approach was performed from the right side to reach the ostium of the left common iliac artery. To increase the support, a non-absorbable suture was stitched up to the tip of the guiding catheter and kept slightly taut like a lasso. Finally, successful penetration was achieved with the novel assistive technique. CONCLUSION: Endovascular treatment for Leriche syndrome is a precious alternative to open surgery. Intraluminal crossing, PIER, and re-entry devices are the most preferred techniques. Increasing the technical success of intraluminal crossing and PIER leads to an apparent reduction in cost.

Cardioneuroablation for treatment of carotid sinus syndrome secondary to oropharyngeal squamous cell cancer.

Head and neck tumors can rarely cause carotid sinus syndrome and this often resolves by surgical intervention or palliative chemoradiotherapy. If these modalities are not an option or are ineffective, the most preferred treatment is permanent pacemaker therapy. Here, we present the first case of cardioneuroablation treatment performed in patient with oropharyngeal squamous cell cancer who developed recurrent asystole and syncope attacks due to compression of the carotid sinus on neck movement.

The Relationship between Coronary Artery Calcium Score and Monocyte to High-Density Lipoprotein Cholesterol Ratio in Patients with Stable Angina Pectoris.

OBJECTIVE: Coronary artery calcification is a cornerstone marker for coronary atherosclerosis. Therefore, the calculation of the coronary artery calcium score has become a routine method in diagnosing coronary artery disease in recent years. Monocyte to high-density lipoprotein cholesterol ratio reflects proatherogenic and antiatherogenic balance, and this ratio is associated with coronary atherosclerosis and cardiovascular events. This study aimed to investigate the value of monocyte to high-densitylipoprotein cholesterol ratio in predicting coronary atherosclerosis, which coronary artery calcium score determines. METHODS: A total of 276 patients with chest pain who underwent coronary computed tomography angiography were enrolled in the study. The patients were divided into 3 groups according to coronary artery calcium score [coronary artery calcium score=0 for very low risk (n=121), coronary artery calcium score=1-99 for low risk (n=100), coronary artery calcium score ≥ 100 for moderate-high risk (n=55)]. The monocyte to high-density lipoprotein cholesterol ratio, neutrophil-to-lymphocyte ratio, systemic immune-inflammation index, and plateletto-lymphocyte ratio were calculated from venous blood samples. RESULTS: Monocyte to high-density lipoprotein cholesterol ratio values were significantly higher in patients with moderate-high coronary artery calcium score (1.29 ± 0.59 vs 1.41 ± 0.56 vs 1.56 ± 0.58, P =.009). However, there were no differences between the groups in terms of other inflammatory markers (neutrophil-to-lymphocyte ratio, systemic immune-inflammation index, and platelet-to-lymphocyte ratio). Age (odds ratio: 1.178; 95% CI: 1.107-1.253; P < .001), dyslipidemia (odds ratio: 14.252; 95% CI: 5.459-37.211; P <.001), smoking (odds ratio: 2.893; 95% CI: 1.317-6.358; P=.008), and monocyte to high-density lipoprotein cholesterol ratio (odds ratio: 2.082 per 1-point increase; 95% CI: 1.016-4.268; P=.045) were independent predictors of coronary artery calcium score in multivariate analysis. CONCLUSION: Our data showed that high monocyte to high-density lipoprotein cholesterol ratio is significantly associated with increased coronary artery calcium score. Monocyte to highdensity lipoprotein cholesterol ratio indicates that it can be applied easily and swiftly in clinics to help predicting the coronary artery disease.

A Novel Electrocardiographic Score Predicts the Severity of Coronary Artery Disease and Clinical Outcomes in Patients with Non-ST Segment Elevation Myocardial Infarction.

Background: There are many electrocardiographic (ECG) changes in non-ST segment elevation myocardial infarction (NSTEMI). However, the diagnostic power is limited in determining the severity of coronary artery disease (CAD) and clinical outcomes. Objective: This study investigated the role of a risk-based ECG score in predicting the severity of CAD and clinical outcomes in NSTEMI patients. Methods: One hundred and fifty-two patients were enrolled in the study. Severe CAD was defined as; intermediate (> 22) or high SYNTAX score (> 32), three-vessel disease, and left main coronary artery lesions. A risk-based ECG score was calculated, and the patients were categorized. All patients were followed up, and mortality and repeat revascularizations were evaluated. Results: The severe CAD group had a significantly higher risk-based ECG score than the non-severe CAD group (p = 0.013). The patients with a high risk-based ECG score had more severe CAD (p = 0.013), higher SYNTAX score (p < 0.001), more three-vessel disease (p = 0.003), coronary artery calcification (p = 0.02), and one-year mortality (p = 0.006) than those with medium or low ECG scores. Multivariate logistic regression analysis showed that a 1-point increase in the risk-based ECG score was associated with a 1.573-fold [95% confidence interval (CI): 1.111-2.227, p = 0.011] increase probability of severe CAD. Kaplan-Meier analysis demonstrated that the high-risk group had a significantly higher one-year mortality rate than the low-risk and moderate-risk groups (hazard ratio: 2.383, 95% CI: 1.395-4.072, p = 0.001). Conclusions: This study demonstrated that higher ECG scores were associated with a higher risk of severe CAD and worse clinical outcomes in NSTEMI patients.

Role of the coronary and non-coronary cardiovascular findings on non-cardiac gated thoracic CT in predicting mortality in SARS-CoV-2 infection.

BACKGROUND: The potential effects of cardiovascular comorbidities on the clinical outcomes in severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection remain unclear. Identification of the coronary and non-coronary cardiovascular findings may help to stratify the patients' prognosis. Therefore, we aimed to evaluate the prognostic impact of the coronary and the non-coronary cardiovascular findings in SARS-CoV-2 patients. METHODS: We studied a total of 594 SARS-CoV-2 patients who were hospitalized and performed a non-cardiac gated thoracic computed tomography. Two blinded radiologists assessed the coronary artery calcification segment involvement score (CACSIS) and non-coronary atherosclerosis cardiovascular findings (NCACVF). The baseline characteristics of the patients and CT findings were evaluated according to survival status. Logistic regression analyses were performed to identify the independent predictors of mortality. RESULTS: At a mean follow-up of 8 (4-12.5) days, 44 deaths occurred (7.4%). Compared to survivors, non-survivors had increased CACSIS [27.3% (CACSIS = 0) vs 25% (CACSIS 1-5) vs 47.7% (CACSIS >5), p < 0.001]. Similarly, on NCACVF, non-survivors had much more major findings compared to survivors (29.5% vs. 2.7%, respectively, p < 0.001). At multivariable analysis, age (p = 0.009), creatinine (p < 0.001), hs-cTnI (p = 0.004) and NCACVF (HR 1.789; 95% CI 1.053-3.037; p = 0.031) maintained a significant independent association with in-hospital mortality. CONCLUSION: Our study shows that coronary and non-coronary cardiovascular findings on non-cardiac gated thoracic CT may help to predict mortality in patients with SARS-CoV-2 infection.
