An Evaluation of Aspirin Treatment Preferences ORIGINAL INVESTIGATION of Physicians in Hypertensive Patients in Terms of Current Guidelines: A Subgroup Analysis of the ASSOS Trial in Turkey.

BACKGROUND: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial has been the largest study ever conducted among patients in Turkey regarding aspirin treatment. In the subgroup analysis of the hypertensive group of the Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial, we aimed to evaluate the physicians' adherence to current guidelines regarding their aspirin treatment preferences. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial is a cross-sectional and multicenter study conducted among 5007 consecutive patients aged ≥18 years. The study population consisted of outpatients on aspirin treatment (80-300 mg). The patient data were obtained from 30 different cardiology clinics of 14 cities from all over Turkey. In this subgroup analysis, patients were divided into 2 groups: the hypertensive group (n=3467, 69.3%) and the group without hypertension (n=1540, 30.7%) according to the 2018 European Society of Cardiology/ European Society of Hypertension Guidelines for the Management of Arterial Hypertension. RESULTS: Aspirin use for primary prevention was higher in patients with hypertension compared to patients without hypertension [328 (21.3%); 1046 (30.2%); P < .001]. Treatment with a dose of 150 mg aspirin (n=172, 5%) was mostly preferred by internists for hypertensive patients (n =226, 6.5%); however, a daily dose of 80-100 mg aspirin therapy (n=1457, 94.6%) was mostly prescribed by cardiologists (n=1347, 87.5%) for patients without hypertension. CONCLUSION: Aspirin was found to be used commonly among patients with hypertension for primary prevention despite the current European Society of Cardiology Arterial Hypertension Guideline not recommending aspirin for primary prevention in patients with hypertension.

B-type natriuretic peptide/ferritin ratio as a predictor of the risk of developing acute renal injury in acute decompensated heart failure.

OBJECTIVES: Acute decompensated heart failure (ADHF) is a clinical condition that requires urgent diagnosis and treatment. Patients present with pulmonary capillary wedge pressure, pulmonary arterial pressure, and venous pressure elevation. Along with the progressive deterioration observed in the clinical picture, impairment or deterioration of kidney function may also occur. In this study, we evaluated the B-type natriuretic peptide (BNP)/ferritin ratio as a predictor of the risk of developing acute renal injury (ARI) in ADHF. METHODS: A total of 157 patients with a diagnosis of ischemic dilated cardiomyopathy for more than 6 months that presented to our clinic with ADHF were included in this cohort study. After the treatment protocol was applied, the sample was divided into two groups as patients with and without ARI. The BNP and ferritin levels were examined along with the routine blood parameters (BNP), and the BNP, ferritin, and BNP/ferritin values were compared between the groups. RESULTS: ARI was present in 34.3% (n = 54) of the patients, who were also found to have higher BNP (892.76 vs. 817.54), lower ferritin (86.78 ± 57.2 vs. 105.46 ± 38.3), and higher BNP/ferritin (10.48 ± 2.14 vs. 7.89 ± 1.89). The multivariate logistic regression analysis revealed the BNP/ferritin ratio as an independent risk factor for ARI (odds ratio = 3.19; 95% CI, 1.92-6.54; P = 0.001). Using the receiver operating characteristic curve, a cutoff value of 9.32 for BNP/ferritin ratio had a sensitivity of 81.8% and a specificity of 93.5% (area under the curve 0.842, P < 0.001) for the prediction of ARI. CONCLUSION: The BNP/ferritin ratio is a new parameter that can be used to draw attention to the severity of the treatment and renal function in ADHF cases in emergency situations.

A new proof for the relationship between erectile dysfunction and atherosclerosis: fragmented QRS?

In patients with coronary artery disease (CAD), fragmented QRS (fQRS) is a practical marker of myocardial ischemia evaluated on electrocardiography (ECG).The current study investigated the connection between FQRS and erectile dysfunction (ED), which is commonly accepted as an early sign and independent predictor of CAD. The study consisted of a 190 ED patients; 47 of them having severe, 44 moderate, 49 mild-to-moderate, and 50 mild ED, and a control group of 51 otherwise healthy adult men. None of the participants had a history of cardiac disease. There was a significant difference among the groups in terms of fQRS; severe, moderate, and mild-to-moderate ED groups had significantly higher rates of fQRS presence on ECG (27.5%, 23.5%, and 22.5%, respectively) in comparison with those of mild ED and the control groups (13.7% and 12.7%, respectively) (p < 0.001). In patients presenting with ED complaints, a fQRS finding on a simple ECG recording may serve as a first sign of the presence of CAD. As far as we know, the present study is the first in the literature assessing the possible relationship between ED and fQRS. On the ECG, the existence of fQRS was considered to be connected with ED; thus, including this basic parameter into the clinical decisions for ED patients may initiate an extensive diagnostic approach for their underlying cardiovascular diseases.

Design and rationale for the ASSOS study: Appropriateness of aspirin use in medical outpatients a multicenter and observational study.

OBJECTIVE: The aim of this study was to describe the current status of aspirin use and the demographic characteristics of patients on aspirin for primary and secondary prevention of cardiovascular diseases. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study (ASSOS) trial was a multicenter, cross-sectional, and observational study conducted in Turkey. The study was planned to include 5000 patients from 14 cities in Turkey. The data were collected at one visit, and the current clinical practice regarding aspirin use was evaluated (ClinicalTrials.gov number NCT03387384). RESULTS: The study enrolled all consecutive patients who were admitted to the outpatient cardiology clinics from March 2018 until June 2018. Patients should be at least 18 years old, have signed written informed consent, and on aspirin (80-325 mg) therapy within the last 30 days. Cardiologists from the hospital participates in the study. Patients were divided into 2 categories according to presence or absence of atherosclerotic cardiovascular disease, namely secondary prevention group and primary prevention group, respectively. The appropriate use of aspirin in the primary and secondary prevention groups was assessed according to the European Society of Cardiology guidelines and US Preventive Services Task Force. The patients' gastrointestinal bleeding risk factors and colorectal cancer risk were evaluated. CONCLUSION: The ASSOS registry will be the most comprehensive and largest study in Turkey evaluating the appropriateness of aspirin use. The results of this study help understand the potential misuse of aspirin in a real-world setting.

Determinants of Chronic Total Occlusion in Patients With Peripheral Arterial Occlusive Disease.

Chronic total occlusion (CTO) is a common finding in 40% of the patients with peripheral arterial disease (PAD). The aim of this study was to investigate the determinants of CTO in patients with PAD. The study included a total of 211 nonanemic patients with PAD. All patients were categorized according to the Fontaine classification. In lower extremity angiography cohorts, CTO- patients were designated as group 1 and CTO+ patients were designated as group 2. Patients with CTO had significantly higher red cell distribution width (RDW), neutrophil-lymphocyte ratio, uric acid, and high-sensitivity C-reactive protein compared to patients without CTO ( P ≤ .001, P = .036, P ≤ .001, and P = .015, respectively). Albumin, total bilirubin, and direct bilirubin were significantly lower in the patients with CTO compared to patients without CTO ( P = .023, P ≤ .001, and P = .049, respectively). Multivariate logistic regression analysis showed that RDW, uric acid, and total bilirubin were independent predictors of CTO in patients with PAD. We demonstrated that increased RDW and uric acid levels and lower total bilirubin values were independently associated with CTO in patients with PAD.

Bilirubin Levels and Thrombus Burden in Patients With ST-Segment Elevation Myocardial Infarction.

We investigated whether serum bilirubin level (a marker of heme oxygenase activity) is a predictor of thrombus burden in patients with acute myocardial infarction. Patients (n = 229; male 72.9%; mean age 63 ± 13.4 years) who were admitted with ST-segment elevation myocardial infarction (STEMI) were enrolled. Patients were divided into 2 groups. Group 1 was defined as low thrombus burden and group 2 was defined as high thrombus burden. Patients with high thrombus burden had higher total bilirubin levels (14.4 [4.3-22.9] vs 7.7 [2.4-20.3] µmol/L, P ≤ .001), (0.84 [0.25-1.34] vs 0.45 [0.14-1.19] mg/dL P ≤ .001) and direct bilirubin levels (3.1 [2.1-8.4] vs 1.7 [0.5-6.5] µmol/L, P ≤ .001), (0.18 [0.03-0.49] vs 0.10 [0.03-0.38] mg/dL, P ≤ .001). At multivariate analysis, total bilirubin (odds ratio: 1.05, 95% confidence interval: 1.03-1.08, P ≤ .001) was the independent predictor of high thrombus burden. In conclusion, total bilirubin level is independently associated with high thrombus burden in patients with STEMI.

New inflammatory markers for prediction of non-dipper blood pressure pattern in patients with essential hypertension: Serum YKL-40/Chitinase 3-like protein 1 levels and echocardiographic epicardial adipose tissue thickness.

The aim of the present study was to investigate whether YKL-40 levels and epicardial adipose tissue (EAT) thickness were associated with non-dipping pattern in essential hypertension (HT). Age- and sex-matched 40 dipper hypertensive patients and 40 non-dipper hypertensive patients were included in the study. Non-dippers had significantly increased EAT thickness and higher YKL-40 and high-sensitivity C-reactive protein levels than dippers. Multivariate logistic regression analysis showed that the EAT thickness and serum levels of YKL-40 and high-sensitivity C-reactive protein were independent predictors of non-dipping pattern in essential HT. In essential HT, presence of non-dipping pattern is associated with increased inflammatory response.

The relation between erectile dysfunction and extent of coronary artery disease in the patients with stable coronary artery disease.

INTRODUCTION: Erectile dysfunction (ED) and coronary artery disease (CAD) are closely related as a result of endothelial dysfunction leading to the restriction of blood flow. ED is a potential independent risk factor of CAD. We investigated the prevalence and severity of ED, the extent of CAD and the time interval between the symptoms of ED and CAD in the stable coronary artery patients. MATERIALS AND METHODS: 161 patients applied coronary angiography were divided into two groups according to SYNTAX score as group 1 (n=81) SYNTAX score ≤22, and group 2 (n=80) SYNTAX score >22. The prevalence and severity of ED was determined by using The International Index of Erectile Function (IIEF). RESULTS: The prevalence of ED was 43.2% in group 1 and 61.3% in group 2 (P=0.022). The score of IIEF was 23.1 (15-29) in group 1, 19.3 (6-29) in group 2; there was a significant difference (P=0.000). In the multivariate logistic regression analysis carried out in order to determine the independent predictors on Syntax score, it was found that LDL (odds ratio: 1.032, 95% confidence interval: 1.009-1.055, P=0.007) and IIEF score (odds ratio: 0.825, 95% confidence interval: 0.733-0.928, P=0.001) were the independent predictors. The time between the symptoms of ED and CAD 30.1 ± 4.8 months in group 1, and 40.5 ± 4.3 months in group 2 (P=0.000). CONCLUSION: The severity of ED is an independent factor predicting the extent of CAD. The early detection of ED enables to make a cardiovascular evaluation. Therefore, taking the cardiovascular risk factors under an aggressive treatment may contribute to prevent the cardiovascular cases which may develop in the future.

Determination of correlation among heart rate variability, left atrium global strain, and nighttime blood pressure among patients with tinnitus.

BACKGROUND: We aimed to examine the correlation among nighttime blood pressure, heart rate variability, and left atrium peak systolic global longitudinal strain among patients with subjective tinnitus. MATERIAL AND METHODS: Eighty patients with tinnitus were assigned to Group 1 and 80 healthy individuals were assigned to Group 2. Clinical blood pressure measurements, ambulatory blood pressure monitoring, and Holter electrocardiography monitoring were performed. All of the cases included in the study were examined with conventional echocardiography and 2-dimensional speckle tracking echocardiography. RESULTS: Mean nighttime systolic blood pressure (130.3±5.4) and mean nighttime diastolic blood pressure (82.8±3.9) in Group 1 were higher than in Group 2 (125.1±5.4 and 80.7±4.7, respectively) (p<0.05). Mean heart rate in Group 1 was significantly lower than in Group 2 but there was no statistically significant difference between the groups in terms of heart rate variability parameters and left atrium peak systolic global longitudinal strain values (p>0.05). CONCLUSIONS: Nighttime systolic blood pressure and nighttime diastolic blood pressure were higher among the patients with tinnitus. In light of these results, we can conclude that both clinical blood pressure measurement and ambulatory blood pressure monitoring are important for patients with tinnitus.

Evaluation of biatrial size and functions by different echocardiographic parameters in patients with acute coronary syndromes.

After acute coronary syndromes (ACS), cardiac remodelling affecting not only ventricles but also both atria is an important problem associated with an increased risk for adverse cardiovascular outcomes. However, it is usually underestimated to evaluate atrial size and functions. The aim of the present study is to compare left and right atrial size and functions in ACS patients with healthy controls during transthoracic echocardiography by means of diameter, area and volume measurements, and pulsed-wave tissue Doppler imaging (TDI). 150 ACS patients (128 male, 22 female) and 25 healthy controls (19 male, 6 female) were enrolled into the study. Of the ACS patients, 75 had ST-segment elevation myocardial infarction (STEMI) and 75 had non-STEMI. Biatrial diameters, areas, and volumes were measured from different echocardiographic views. Atrial total emptying fraction and expansion index values were calculated from volume measurements. By the pulsed-wave TDI of the atrial walls; peak systolic (S'), peak early diastolic (E'), and peak late diastolic (A') velocities were measured. Almost all left atrial parameters for diameter, area, and volume measurements were higher in ACS patients. Similarly, they had higher values for the same right atrial parameters. Left and right atrial total emptying fraction and expansion index values were lower in ACS patients than controls. All left and right atrial walls had lower S' and E' velocities in ACS patients. ACS cause important alterations in the biatrial size and functions evaluated by echocardiographic diameter, area and volume measurements, and pulsed-wave TDI.
