RESUMEN

Aim    In heart failure (HF) patients with iron deficiency, cardiac electrical irregularity is a cause of arrhythmias. The aim of our study was to evaluate the effect of ferric carboxymaltose (FCM) treatment on T wave peak to end (Tp-e) interval and the Tp-e / QT and Tp-e / corrected QT (QTc) ratios that reflect the transmural dispersion of repolarization in HF patients with iron deficiency.Material and methods    Forty HF patients with iron deficiency that were treated with FCM were included in our single center, observational study. Repolarization parameters on electrocardiograms recorded before and 12 wks after FCM treatment were compared. Additionally, these parameters were compared with ventricular repolarization parameters of 40 healthy age and gender matched individuals and with another group of 40 HF patients without iron deficiency.Results    In the HF patients with iron deficiency, the Tp-e interval and the Tp-e / QT and Tp-e / QTc ratios before FCM treatment were 103.7±19.1 ms, 0.25± 0.04, 0.23±0.04, respectively. These values were higher compared to the healthy the group and HF group without iron deficiency (p<0.001). In the HF patients with iron deficiency, the Tp-e interval and the Tp-e / QT and Tp-e / QTc ratios after FCM treatment were lower compared to pre-treatment and similar to the HF patients without iron deficiency (89.4±18.6 ms, 0.22±0.04, 0.20±0.04, respectively; p<0.001).Conclusion    FCM treatment of HF patients with iron deficiency corrects prolonged Tp-e interval and high Tp-e / QT and Tp-e / QTc ratios, which are risk factors for ventricular arrhythmias.

RESUMEN

Background/aim: This study aimed to evaluate the effect of successful percutaneous mitral balloon valvuloplasty (PMBV) on left ventricular systolic functions using strain and strain rate echocardiography in moderate­severe mitral stenosis (MS) patients with normal left ventricular systolic function confirmed by conventional echocardiography. Materials and methods: Patients with moderate­severe MS who had undergone successful PMBV were included. Conventional echocardiographic parameters were evaluated before and after PMBV. Peak systolic strain and strain rate values of basal, mid, and apical segments of the left ventricular anterior, inferior, septum, and lateral walls were determined. Results: After PMBV, significant decreases were determined in the peak and mean gradients of the mitral valve and pulmonary artery pressure, but a significant increase in the mitral valve area. Significant increases (improvement) were determined in the peak systolic strain and strain rate in the basal, mid, and apical segments of the left ventricular septum, lateral, anterior, and inferior walls and in the left ventricular global peak systolic strain (­17.32 ± 0.58% vs. ­12.38 ± 1.06%) and strain rate (­1.65 ± 0.07 vs. ­1.22 ± 0.12). Conclusion: Strain and strain rate echocardiography can be used for quantitative evaluation of the effect of PMBV on the left ventricular systolic functions in moderate­severe MS patients.

RESUMEN

BACKGROUND: In this study, we examined the relative usefulness of serum copeptin levels as a surrogate marker of vasopressin (AVP) in adult polycystic kidney disease (ADPKD) by correlating it with baseline and longitudinal changes in markers of both renal function and common CVD manifestations (hypertensive vascular disease, atherosclerosis and endothelial dysfunction) that accompany the progression of this disease. METHODS: We studied a cohort of young and otherwise healthy ADPKD patients (n = 235) and measured cardiovascular function using flow-mediation dilatation (FMD), carotid intima media thickness (cIMT) and pulse wave velocity (PWV), as well as serum copeptin (commercial ELISA, a stable marker of AVP activity). The same analyses were carried out at baseline and after 3 years of follow-up. RESULTS: At baseline, median eGFR was 69 mL/min./1.73 m2, mean FMD 6.9 ± 0.9%, cIMT 0.7 ± 0.1 mm, and PWV 8.1 ± 1.2 m/s. At follow-up, equivalent values were 65 (44-75) mL/min./1.73 m2, 5.8 ± 0.9%, 0.8 ± 0.1 mm. and 8.2 ± 1.3 m/s. with all changes statistically significant. Plasma copeptin also rose from 0.62 ± 0.12 to 0.94 ± 0.19 ng/mL and this change correlated with ΔeGFR (-0.33, p < 0.001), ΔFMD (0.599, p < 0.001), ΔcIMT (0.562, p < 0.001) and ΔPWV (0.27, p < 0.001) also after linear regression modeling to correct for confounders. Finally, ROC analysis was done for a high baseline copeptin with ΔeGFR [cut-off:≤59], ΔFMD [cut-off: ≤7.08], ΔcIMT [cut-off:>0.76], and ΔPWV [cut-off:≤7.80]. CONCLUSIONS: Vascular dysfunction as reflected by FMD and cIMT, but not PWV or an altered cardiac geometry, precede most other signs of disease in ADPKD but is predicted by elevated levels of the circulating AVP-marker copeptin.

RESUMEN

Numerous studies have investigated a probable association between androgenetic alopecia (AGA) and cardiovascular disease (CVD) by researching limited and dispersed parameters. We aimed to evaluate both traditional and non-traditional cardiovascular risk factors in male patients with early-onset AGA. This case-control study included 68 participants: 51 male patients with early-onset AGA and 17 healthy male controls. Patients with AGA were classified into three groups according to the Hamilton-Norwood scale and the presence of vertex hair loss. Traditional and non-traditional cardiovascular risk factors were examined in all study subjects. Metabolic syndrome was diagnosed in 25 patients with AGA and in two control subjects (p < 0.05). The carotid intima-media thickness values were found to be significantly higher in patients with vertex pattern AGA than in patients without vertex baldness and controls (p < 0.05). The pulse-wave velocity values were also found to be significantly higher in patients (p < 0.001). A limitation of this study was the small study population. In conclusion, vertex pattern AGA appears to be a marker for early atherosclerosis. This finding supports the hypothesis that early-onset AGA alone could be an independent risk factor for CVD and metabolic syndrome.

RESUMEN

BACKGROUND: Atrial electromechanical delay (AEMD) times were considered independent predictors of cardiovascular morbidity among the general population. We aimed at evaluating AEMD times and other risk factors associated with 2-year combined cardiovascular (CV) events in HD patients. MATERIAL AND METHODS: Sixty hemodialysis (HD) and 44 healthy individuals were enrolled in this prospective study. Echocardiography was performed before the mid-week dialysis session for HD patients. Data were expressed as mean ± SD. Spearman test was used to assess linear associations. Survival was examined with the Kaplan-Meier method. Multivariate Cox regression analysis was used to determine the predictors of combined CV events in this cohort. RESULTS: At the beginning of the study, left intra-atrial-AEMD times were significantly longer in HD patients compared to the left intra-atrial-AEMD times in healthy individuals. After 24 months, 41 patients were still on HD treatment and 19 (31.6%) had died. Serum triglyceride, total cholesterol and albumin were found to be higher and C-reactive protein (CRP) levels, left intra-atrial EMD time (LIAT) and interatrial EMD times were found to be lower in survived HD patients. With the cut-off median values of 3.5 g/dl for albumin, 0.87 mg/dl for CRP, 157 mg/dl for total cholesterol and 151 mg/dl for triglyceride, the Kaplan-Meier curves demonstrated significant differences in terms of all-cause mortality. We also demonstrated the Kaplan-Meier survival curves of HD patients according to tertile values of LIAT. Cox regression analysis revealed that increased CRP and higher LIAT were found to be independent predictors of combined CV events. CONCLUSIONS: Increased LIAT and inflammation were found to be closely associated with 2 years combined CV events and all-cause mortality in HD patients.

RESUMEN

BACKGROUND: Migraine is a common type of primary headache predominantly seen in women. This study aimed to evaluate endothelial function in patients with migraine using pulse wave velocity (PWV). METHODS: The study included 73 patients with newly diagnosed migraine and 80 healthy subjects. All patients and controls underwent baseline transthoracic echocardiography and PWV measurements. Patients were randomized to three groups to receive propranolol, flunarizine or topiramate, and the measurements were repeated at the end of 1 month. RESULTS: The newly diagnosed migraine patients and the control group exhibited no differences in baseline clinical characteristics, and the measurements showed that PWV was 7.4 ± 1.0 m/s in the patient group and 6.0 ± 1.0 m/s in the control group (p < 0.001). The same measurements were repeated during a control visit at the end of 1 month. Following treatment, a significant decrease was observed in PWV in all patient groups compared to baseline (p < 0.001). Subgroup analysis showed significantly decreased PWV in all drug groups, with the most prominent decrease in the topiramate group. CONCLUSIONS: The increased PWV demonstrated in migraine patients in this study stands out as an additional parameter elucidating endothelial dysfunction in these patients. Decreasing the number of migraine attacks with prophylactic treatment may reduce PWV and decrease cardiovascular risk in long-term follow-up.

RESUMEN

INTRODUCTION: Arterial stiffness is a risk marker for cardiovascular events in peritoneal dialysis (PD) patients. Strict volume control strategy has been shown to result in better cardiac functions and control of hypertension in these patients. The aim of the study was to identify the determinants of arterial stiffness and evaluate the changes in cardiac biomarkers in PD patients under strict volume control strategy. METHODS: 58 PD patients were enrolled into this prospective observational study. Arterial stiffness determined by aortic pulse wave velocity (PWV), echocardiography, ambulatory blood pressure and NT-pro-BNP levels were measured at baseline and at first year. RESULTS: The mean age of the patients was 46.4 ± 14 years. 30 patients were on automated PD (APD) and 28 on continuous ambulatory PD (CAPD) group. In both groups, there were significant differences in PWV values at baseline and at the end of the study. A similar decrease was observed with NT-proBNP and PWV levels. In addition, a significant improvement was found in echocardiographic parameters in all patients. Comparison of APD and CAPD groups with respect to change in one year, showed no difference in echocardiographic findings, while the reduction in PWV, NTproBNP and blood pressure values was higher in the CAPD group. CONCLUSIONS: In PD patients, strict volume control leads to a reduction in NT-pro-BNP levels, better control of blood pressure and significant improvements in cardiac functions and arterial stiffness.

RESUMEN

BACKGROUND/AIMS: Early onset of hypertension and its consequences account for the great majority of deaths in patients with autosomal dominant polycystic kidney disease (ADPKD). Renin-angiotensin system (RAS) components have been shown in ADPKD kidneys independent of systemic RAS. Thus, we examined the urinary angiotensinogen (UAGT) levels as a biomarker of intrarenal RAS status in ADPKD patients with/without hypertension and healthy subjects. METHODS: Eighty-four ADPKD patients (43 with hypertension and 41 without hypertension) and 40 healthy controls were studied cross-sectionally. Patients with glomerular filtration rate <60 ml/min were excluded from the study. Hypertension was diagnosed with ambulatory blood pressure monitoring. Urinary and plasma concentration of angiotensinogen, spot urine microprotein and creatinine (UCre) levels were recorded for each participant. RESULTS: UAGT/UCre levels were higher in hypertensive ADPKD patients (23.7 ± 8.4) compared with normotensive ADPKD patients (16.6 ± 5.2) and healthy controls (6.9 ± 3.3; p < 0.001). In univariate analysis, UAGT correlated with systolic blood pressure, diastolic blood pressure (DBP) and proteinuria. The independence of these correlations was analyzed in a regression model, and UAGT was shown to be significantly predicted by proteinuria and DBP. CONCLUSION: Intrarenal RAS activation which is monitored by UAGT levels clinically may be a harbinger of hypertension and kidney disease in ADPKD patients.

RESUMEN

BACKGROUND/AIMS: Patients with autosomal dominant polycystic kidney disease (ADPKD) exhibit endothelial dysfunction (ED) despite normal levels of renal function. Hyperuricemia occurs in these patients and has been postulated to affect ED through the generation of oxidative stress. We therefore investigated the prevalence of ED and its association with serum uric acid levels in early-stage ADPKD. METHODS: A cross-sectional design was used for the assessment of prevalent patients with early-stage (normal renal function) ADPKD (n = 91) from two academic medical centers. ED was assessed using ischemia-induced forearm flow-mediated vasodilation (FMD). Serum uric acid levels were evaluated using an Olympus AU2700 autoanalyzer. RESULTS: ADPKD patients with higher serum uric acid levels had a higher asymmetric dimethylarginine (ADMA) level (1.19 ± 0.2 vs. 1.47 ± 0.3, p < 0.001) and lower FMD rates (8.1 ± 1.3 vs. 6.8 ± 0.7, p < 0.001). In multiple regression analysis for predictors of cohort FMD, uric acid (ß = -0.32, p < 0.001), ADMA (ß = -0.36, p < 0.001), high-sensitivity C reactive protein (CRP; ß = -0.32, p < 0.001) and estimated glomerular filtration rate (eGFR; ß = 0.33, p < 0.001) all predicted FMD. CONCLUSIONS: In early-stage ADPKD patients, uric acid levels, serum ADMA and eGFR all independently predict ED in a similar manner. Future studies are needed to investigate the causes of elevated serum uric acid, ADMA and CRP in these patients.

RESUMEN

BACKGROUND: Activation of the reninangi otens in-aldosterone system has an important role in the pathophysiology of heart failure with reduced ejection fraction. While the effects of systemic reninangi otens in-aldosterone system activation on heart failure with reduced ejection fraction are well known, the impact of the local reninangi otens in-aldosterone system on heart failure with reduced ejection fraction is not fully understood because of limited clinical research. This study aimed to investigate the effect of urinary angiotensinogen level, an accepted indicator of local reninangi otens in-aldosterone system activation, on all-cause mortality in patients with heart failure with reduced ejection fraction. METHODS: This retrospective, single-center study included 60 patients with baseline urinary angiotensinogen data and survival/mortality data at 4 years. Urinary angiotensinogen values were standardized to the urinary creatinine value measured from the same urine sample. The median urinary angio tensi nogen /urin ary creatinine value among all patients (114 µg/g) was used as a cutoff to divide the patients into 2 groups. Mortality data were obtained from the national registry systems or by telephone. RESULTS: Comparison of all-cause mortality in the 2 groups showed that 22 deaths (71%) occurred in the group with a urinary angio tensinogen/urinary creatinine ratio above the median and 10 deaths (35.5%) occurred in the group of patients with urinary angio tensinogen/urinary creatinine equal to or below the median value (P =.005). CONCLUSION: Our study suggests that urinary angiotensinogen can be used as a new biomarker in the prognosis and follow-up of heart failure patients.

RESUMEN

OBJECTIVE: This study aimed to define the association between altitude and ticagrelor-associated dyspnea in patients with acute coronary syndrome (ACS). METHODS: We studied consecutive patients with de novo ACS who were admitted to two centers at a low altitude (18 and 25 m, n = 65) and two centers at a high altitude (1313 and 1041 m, n = 136). We managed them with ticagrelor between May 2017 and September 2017. Patients with ACS underwent an interventional procedure within <90 minutes in those with ST elevation and within <3 hours in those without ST elevation. We recorded the incidence of dyspnea in patients with ACS receiving ticagrelor therapy. RESULTS: The mean age was 59.5 ± 10 years, and the mean ejection fraction was 43% ± 18%. A total of 110 (56.7%) patients had ST elevation and 84 (43.3%) did not. There were no significant differences in cardiac risk factors, concurrent medications, or procedural variables between the two groups. Dyspnea developed during hospitalization in 53 (38%) patients from high-altitude centers and in 13 (20%) patients from low-altitude centers (66 patients represented 32% of the total ACS cohort). CONCLUSIONS: Dyspnea is a common multifactorial symptom in patients following development of ACS. Ticagrelor-induced dyspnea appears to be associated with altitude.

RESUMEN

BACKGROUND/AIMS: Cardiovascular disease is the main cause of morbidity and mortality in autosomal-dominant polycystic kidney disease (ADPKD) patients. To clarify temporal relationship between ADPKD, hypertension and the loss of renal function, we examined these factors in patients with early-stage ADPKD who did not yet have hypertension. METHODS: Fifty patients with ADPKD (42% males, 36.6 ± 9.9 years, no blood pressure medication) and 50 healthy controls (44% males, 35.4 ± 6.4 years) were studied cross-sectionally. Pulse wave velocity (PWV), cardiac morphology and function, aortic elastic indexes, estimated glomerular filtration rate (eGFR), 24-hour ambulatory blood pressure, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and highly sensitive C-reactive protein (hs-CRP) were measured in all participants, using conventional methods. RESULTS: Despite a normal blood pressure, aortic stiffness index and pulse wave velocity values were increased in patients compared to controls (6.8 ± 4.7 vs. 5.1 ± 3.3, p = 0.043 and 9.6 ± 1.3 vs. 5.8 ± 1.1 m/s, p < 0.001). In univariate analysis, IL-6, TNF-α, hs-CRP and eGFR were all significantly correlated with PWV. The independence of these correlations were analyzed in a regression model, and showed PWV to be significantly predicted by IL-6, TNF-α and hs-CRP. CONCLUSION: Increased arterial stiffness and pulse wave velocity are early manifestations of ADPKD appearing before hypertension or reduced eGFR. However, these vascular abnormalities are related to signs of systemic low grade inflammation, suggesting a common pathophysiological mechanism apparently present also in other vascular diseases but yet to be elucidated.

RESUMEN

BACKGROUND: We aimed to determine the status of the autonomic nervous system in patients with autosomal-dominant polycystic kidney disease (ADPKD) who were normotensive and had normal renal function. METHODS: A total of 28 normotensive ADPKD patients with normal renal function and 30 healthy control subjects consented to participate in the study. Heart rate recovery (HRR) indices were defined as the reduction in heart rate from the rate at peak exercise to the rate at the 1st, 2nd, 3rd and 5th minutes after the cessation of the exercise stress test; these results were indicated HRR(1), HRR(2), HRR(3) and HRR(5), respectively. RESULTS: The 1st- and 2nd-minute HRR indices of patients with ADPKD were significantly lower than those of the healthy control group (27.1±7.9 vs 32.0±7.9; p=0.023 and 46.9±11.5 vs 53.0±9.0; p=0.029, respectively). Similarly, HRR indices after the 3rd and 5th minutes of the recovery period were significantly lower in patients with ADPKD when compared with indices in the control group (56.7±12.0 vs 65.1±11.2; p=0.008 and 62.5±13.8 vs 76.6±15.5; p =0.001, respectively). CONCLUSION: Impaired HRR index is associated with normotensive early-stage ADPKD patients. Increased renal ischemia and activation of the renin-angiotensin-aldosterone system (RAAS) may contribute to impairment in the autonomic nervous system in these patients before the development of hypertension. Even if ADPKD patients are normotensive, there appears to be an association with autonomic dysfunction and polycystic kidney disease.

RESUMEN

OBJECTIVE: Cryptogenic stroke (CS) is considered to be the most common stroke subtype in young patients. The Risk of Paradoxical Embolism (RoPE) score is a tool that stratifies patients with CS according to the probability of patent foramen ovale (PFO). The aim of this retrospective study is to determine the prevalence of PFO in young patients with transesophageal echocardi- ography (TEE) and to evaluate the role of RoPE score in PFO-related strokes. METHODS: The medical records of patients with acute arterial ischemic stroke, who underwent TEE between 2016 and 2020, were reviewed. Patients aged 18-55 years were included in the study. Presence of PFO, PFO characteristics, presence of atrial septal aneurysm (ASA) were detected by examining the image records of the patients from the archive system. RoPE score was calculated for all patients as determined in the literature. RESULTS: Totally, 50 CS patients were included in the study (mean age: 39.6±9.4 years). PFO was detected in 19 (38%) patients and it was the most common cardiac abnormality in CS patients. ASA was detected in 7 (14%) patients. The mean RoPE score in patients with PFO was higher than patients without PFO, although it did not reach statistical significance (7.68±1.1 versus 6.77±1.9 P = .07). Eighteen of 19 patients with PFO had a RoPE score ≥7. CONCLUSION: In our study, PFO prevalence in the CS patients was higher than normal popula- tion. In patients with cryptogenic stroke, the RoPE score can help determine the probability of PFO related stroke and which patients should undergo TEE.

RESUMEN

BACKGROUND: Dipeptidyl peptidase 3 (DPP-3) is an intracellular enzyme that causes hemodynamic instability and cardiac depression in several cases such as cardiogenic shock, sepsis and burns where DPP-3 is released into the blood due to cell death. Data on the effect of higher DPP-3 levels on acute coronary syndrome (ACS) patients are currently lacking. The aim of this study was to evaluate the effect of DPP-3 levels on ACS patients. METHODS: In this prospective study, we included ACS patients including STEMI and non-STEMI groups and a control group to compare various demographic, echocardiographic and laboratory parameters including DPP-3. DPP-3 levels were measured at 24th, 48th, and 72nd h from the onset of symptoms in ACS patients and then compared with left ventricle ejection fraction (LVEF) for the assessment of left ventricle systolic function. RESULTS: A total of 70 ACS patients (age 62.5 ± 11 years, 68.6% male) were recruited and 48 normal individuals were included as control group (age 61.1 ± 10 years, 66.7% male). It has been demonstrated that DPP-3 levels are significantly higher in the ACS group than the control group like troponin I levels. DPP-3 levels were found to be one of the independent predictors of LVEF similar to NT-proBNP and troponin I. CONCLUSIONS: This study suggests that DPP-3 could be an important indicator of myocardial depression predicting left ventricle systolic function in ACS.

RESUMEN

Introduction and aim Sickle cell anemia (SCA) is the most common hemoglobinopathy worldwide, and cardiovascular diseases are the most common causes of death. In these patients, cardiac remodeling begins from childhood and leads to sickle cell cardiomyopathy in the following years. Concentric hypertrophy and eccentric hypertrophy are known to predict early cardiac events. This study aims to reveal the relationship between cardiac remodeling types and survival in patients with SCA and investigate the factors that may affect left ventricular mass. Materials and methods A total of 146 patients with SCA were included in the study, and the left ventricular mass index (LVMI) and relative wall thickness (RWT) of the patients were calculated according to echocardiographic measurements, and the patients were categorized into normal, concentric remodeling (CR), concentric hypertrophy (CH), and eccentric hypertrophy (EH) groups. Results The median age of the patients is 32 (18-72). In logistic regression analysis, hemoglobin S (HbS) and ferritin levels were independent predictors for LVMI (p = 0.01 and p < 0.001, respectively). It was observed that 56 (38.4%) of the patients had normal left ventricles, 24 (16.4%) had CR, 21 (14.4%) had CH, and 45 (30.8%) had EH. 31 (21.2%) of the patients died. When we look at the survival curves, there was a statistically significant difference between the four groups (log-rank p < 0.001). It was observed that patients with EH were the group with the lowest probability of survival. Conclusion Cardiac death is one of the most common causes of death in patients with SCA. Early detection of cardiac disorders and starting treatment may be important in reducing mortality in these patients.

RESUMEN

BACKGROUND: Indications and appropriateness of aspirin use have not been well investigated in Turkey. AIMS: To investigate the prescription patterns and appropriateness of aspirin in a real-world clinical setting. STUDY DESIGN: Cross-sectional study. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study (ASSOS) is a cross-sectional and multicenter study that included 5007 consecutive patients aged 18 or over who presented to 30 different cardiology outpatient clinics from 14 cities throughout Turkey. Only patients using aspirin (80-325 mg) were included. The study population was divided into 2 groups regarding the use of aspirin: primary prevention (PP) group and secondary prevention (SP) group. The indication of aspirin use was evaluated following the 2016 European Society of Cardiology (ESC) and the 2016 United States Preventative Services Task Force (USPTF) guidelines in the PP group. RESULTS: A total of 5007 patients (mean age 62.15 ± 11.05, 39% female) were enrolled. The PP group included 1132 (22.6%) patients, and the SP group included 3875 (77.4%) patients. Of the 1132 patients, inappropriate use of aspirin was determined in 100% of the patients according to the ESC guidelines, and 71% of the patients according to the USPTF guidelines. Multivariate logistic regression analysis showed age OR: 0.98 CI (0.97-0.99) P = .037, smoking OR: 0.60 CI (0.44-0.82) P = .001, heart failure OR: 2.11 CI (1.14-3.92) P = .017, hypertension OR: 0.51 CI (0.36-0.74) P < .001, diabetes mellitus OR: 0.34 CI (0.25-0.47) P < .001, oral anticoagulant use OR: 3.01 CI (1.10-8.25) P = .032, and female sex OR: 2.73 CI (1.96-3.80) P < .001 were independent predictors of inappropriate aspirin use in PP patients. CONCLUSION: Although there are considerable differences between the USPTF and the ESC guidelines with respect to recommendations for aspirin use in PP, inappropriate use of aspirin in Turkey is frequent in real-world practice for both guidelines. Besides, heart failure, oral anticoagulant use, and the female sex of the patients were independent predictors of inappropriate use of aspirin.

RESUMEN

BACKGROUND: We aimed to determine the effect of blood lactate levels on cardiovascular (CV) death and hospitalization for heart failure (HF) in acute HF patients with reduced left ventricular ejection fraction (EF). METHODS: Eighty-five acute HF patients with reduced ejection fraction were divided into two groups according to admission blood lactate levels. 48 of them had low blood lactate levels (< 2 mmol/l) and 37 of them had high blood lactate levels (≥ 2 mmol/l). Patients with acute coronary syndrome, cardiogenic shock, sepsis and low blood pressure at admission were excluded from the study. Primary endpoint is the composite of cardiovascular (CV) death and hospitalization for heart failure (HHF) in 6-month follow-up. Secondary endpoint is the change in NT-proBNP levels from admission to 72 h. RESULTS: Baseline characteristics of patients were similar in two groups. On baseline echocardiographic evaluation; patients with high lactate revealed a higher mitral E/A ratio (2.34 [0.43-3.31], p = 0.008) and a lower TAPSE ratio (14 [10-27], p = 0.008) than patients with low lactate levels. Over a median follow-up period of 6 months, the primary end point occurred in 28 (75.7%) of 37 patients assigned to high lactate group and in 20 (41.7%) of 48 patients assigned to low lactate group (p = 0.006). High lactate levels significantly increased the risk of CV death and HHF at 6 months by nearly 5.35-fold in acute HF patients with reduced EF. The change in NT-proBNP levels at 72nd hour after admission were similar between two groups. CONCLUSION: Higher lactate levels at admission related with higher HHF at 6 months and may be related with higher risk of CV death in acute HF patients with reduced EF.

RESUMEN

OBJECTIVE: Dilation of one or more coronary artery segments to a diameter at least 1.5 times that of a normal adjacent segment is referred to as coronary artery ectasia (CAE). Adropin is a protein involved in endothelial function and is shown to have a protective effect on the regulation of cardiac functions. Atherosclerosis and endothelial dysfunction play an important role in the development of CAE. The aim of this study was to investigate the association between serum adropin levels and isolated CAE. METHODS: Patients with stable angina pectoris who underwent coronary angiography (CAG) between August 2017 and July 2018 were evaluated prospectively. A total of 92 subjects were included in the study-40 patients over 18 years old and diagnosed with isolated CAE based on CAG findings and a control group of 52 patients. RESULTS: Serum adropin level was found to be significantly lower in the isolated CAE group compared to the control group (1019.57 pg/mL and 1151.10 pg/mL, respectively, p=0.010). The isolated CAE group also exhibited a significantly higher mean platelet volume than that in the control group (10.75 fL and 10.17 fL, respectively, p=0.011). CONCLUSION: Our results show that there is an association between low serum adropin level and isolated CAE.

RESUMEN

BACKGROUND: Statins are commonly used in the secondary prevention of coronary artery disease. Studies have shown that the rate of statin use is low among patients with coronary artery disease. In this study, we aimed to investigate the reasons for poor patient compliance with statin treatment. METHODS: A total of 504 patients diagnosed with coronary heart disease were included in the study. Patients were asked 5 questions to assess their level of knowledge about statin therapy. RESULTS: Among the patients not using statins, 42% stated they did not take the medication because their cholesterol was not high or they did not know they should renew their prescription when they ran out and 35% because they were influenced by news reports in the media suggesting that cholesterol-lowering drugs were harmful. When patients who were aware of the pleiotropic/cardioprotective effects of statins were compared with patients who were not, the more knowledgeable patients had lower noncompliance rate and mean LDL-C level and a higher rate of LDL-C level optimization. CONCLUSION: We found that patients who are aware of the pleiotropic effects of statins were more compliant with treatment. We believe that spending more time explaining and emphasizing the mechanisms of action, reason for prescribing, and necessary treatment duration of drugs that patients must use will result in greater compliance and improve patient care. In this way, patients may be less influenced by misinformation presented by the media.
