RESUMO

BACKGROUND: Optimal glycemic control is necessary to prevent cardiovascular events in patients with type 2 diabetes. The positive impact of sodium-glucose cotransporter-2 inhibitors (SGLT2i) on cardiovascular events and mortality in these patients has been demonstrated by previous studies although the mechanism is unclear. AIMS: We aimed to compare the influence of SGLT2i on left ventricular remodeling and strain in diabetic patients with coronary artery disease (CAD) and without CAD during 6-month follow-up. METHODS: Between October 2021 and June 2022, 100 diabetic patients with preserved ejection fraction (HbA1c levels 6.5-10%) were started on SGLT2i (empagliflozin or dapagliflozin) and were prospectively followed up. Conventional and speckle-tracking echocardiography was performed by blinded sonographers, at baseline and then at 1 month and 6 months of treatment. After 6 months, the initial and biochemical blood tests were administered, and N-terminal pro-B-type natriuretic peptide levels of the patients were measured. RESULTS: Patients with CAD were older (P = 0.008), more frequently hypertensive (P = 0.035), and had dyslipidemia (P = 0.021). N-terminal pro-B-type natriuretic peptide levels did not change significantly after treatment in both groups. Left ventricular ejection fraction, global, 2-chamber, and 3-chamber strain values were improved significantly following SGLTi administration for the overall patient cohort, regardless of CAD status (P < 0.05 for all groups). CONCLUSIONS: Treatment with SGLT2i resulted in improvement in left ventricular strain parameters, which indicates that they might have a positive impact on outcomes for diabetic patients with preserved EF.

RESUMO

Background and Objectives: Pulmonary arterial hypertension (PAH) is a rare chronic disease of the small pulmonary arteries that causes right heart failure and death. Accurate management of PAH is necessary to decrease morbidity and mortality. Understanding current practices and perspectives on PAH is important. For this purpose, we intended to determine physicians' knowledge, attitudes, and practice patterns in adult pulmonary arterial hypertension (PAH) in Turkey. Materials and Methods: Between January and February 2022, an online questionnaire was sent via e-mail to all cardiologists and pulmonologists who were members of the Turkish Society of Cardiology (TSC) and the Turkish Thoracic Society (TTS). Results: A total of 200 physicians (122 pulmonologists and 78 cardiologists) responded to the questionnaire. Cardiologists were more frequently involved in the primary diagnosis and treatment of PAH than pulmonologists (37.2% vs. 23.8%, p = 0.042). More than half of the physicians had access to right heart catheterization. In mild/moderate PAH patients with a negative vasoreactivity test, the monotherapy option was most preferred (82.8%) and endothelin receptor antagonists (ERAs) were the most preferred group in these patients (73%). ERAs plus phosphodiesterase-5 inhibitors (PDE-5 INH) were the most preferred (69%) combination therapy, and prostacyclin analogues plus PDE-5 INH was preferred by only pulmonologists. Conclusions: Overall, clinical management of patients with PAH complied with guideline recommendations. Effective clinical management of PAH in specialized centers that having right heart catheterization achieve better outcomes.

RESUMO

OBJECTIVE: The purpose of this study was to explore the efficacy of the triglyceride glucose (TyG) index on in-hospital mortality in nondiabetic coronavirus disease 2019 (COVID-19) patients with myocardial injury. METHODS: This was a retrospective study, which included 218 nondiabetic COVID-19 patients who had myocardial injury. The TyG index was derived using the following equation: log [serum triglycerides (mg/dL) ×fasting blood glucose (mg/dL)/2]. RESULTS: Overall, 49 (22.4%) patients died during hospitalization. Patients who did not survive had a higher TyG index than survivors. In multivariate Cox regression analysis, it was found that the TyG index was independently associated with in-hospital death. A TyG index cutoff value greater than 4.97 was predicted in-hospital death in nondiabetic COVID-19 patients with myocardial damage, with 82% sensitivity and 66% specificity. A pairwise evaluation of receiver operating characteristic (ROC) curves demonstrated that the TyG index (AUC: 0.786) had higher discriminatory performance than both triglyceride (AUC: 0.738) and fasting blood glucose (AUC: 0.660) in predicting in-hospital mortality among these patients. CONCLUSIONS: The TyG index might be used to identify high-risk nondiabetic COVID-19 patients with myocardial damage.

RESUMO

Introduction: The focus of this research was to explore the link between CRP (C-reactive protein) /albumin ratio (CAR), a novel inflammatory response marker, and no-reflow (NR) phenomena in non-ST elevation myocardial infarction (non-STEMI) patients during percutaneous coronary intervention (PCI). Methods: The current study recruited 209 non-STEMI participants who underwent PCI. The patients were divided into two groups based on their post-intervention Thrombolysis in Myocardial Infarction (TIMI) flow grade; those with and without NR. Results: In all, 30 non-STEMI patients (6.9%) had NR after PCI. CAR values were substantially greater in the NR group. The CAR was identified to be a determinant of the NR (OR: 1.250, 95% CI: 1.033-1.513, P=0.02), although CRP and albumin were not independently related with NR in the multivariate analysis. In our investigation, low density lipoprotein-cholesterol levels and high thrombus burden were also predictors of the occurrence of NR. According to receiver operating characteristic curve evaluation, the optimal value of CAR was>1.4 with 60% sensitivity and 47% specificity in detecting NR in non-STEMI patients following PCI. Conclusion: To the best of knowledge, this is the first investigation to demonstrate that the CAR, a new and useful inflammatory marker, can be utilized as a predictor of NR in patients with non-STEMI prior to PCI.

RESUMO

Introduction: P-wave dispersion (PWD) obtained from the standard 12-lead electrocardiography (ECG) is considered to reflect the homogeneity of the atrial electrical activity. The aim of this investigation was to evaluate the effect of percutaneous chronic total occlusion (CTO) revascularization on the parameters of P wave duration and PWD on ECG in cases before and after procedure at 12th months. Methods: We analyzed 90 consecutive CTO cases who were on sinus rhythm and underwent percutaneous coronary intervention (PCI). P-wave maximum (P-max) and P-wave minimum (P-min), P-wave time, and PWD were determined before and twelve months after the CTO intervention. The study population was categorized into two groups as successful and unsuccessful CTO PCI groups. Results: The CTO PCI was successful in 71% of cases (n=64) and it was unsuccessful in 29% of cases (n=26). Both groups, except for age and hypertension, were similar in terms of demographic and clinical aspects. CRP levels were significantly elevated in the unsuccessful CTO PCI group. Pre-PCI ECG parameters showed no significant difference. Irrespective of the target vessel revascularization, we observed that PWD and P-max values were significantly lower in the 12th months follow-up. In all Rentrop classes, PWD values were significantly decreased at 12th months follow-up in comparison to the pre-CTO PCI values. Conclusion: This study has determined that PWD and P-max, which are both risk factors for atrial arrhythmias, are significantly reduced within 12th months after successful CTO PCI regardless of the target vessel.

RESUMO

Ticagrelor is believed to be a more potent and faster antiplatelet agent compared with clopidogrel and may result in lower ischemic outcomes in patients with acute coronary syndrome. However, the best strategy of switching from ticagrelor to clopidogrel is unclear. Current guidelines advocate clopidogrel bridging with a 600 mg loading dose (LD). This study aimed to compare the safety and feasibility of switching protocols from ticagrelor to clopidogrel 600 mg or 300 mg LD in patients with unstable angina pectoris (USAP). One hundred and eighty patients with USAP undergoing adhoc percutaneous coronary intervention (PCI) received preprocedural ticagrelor 180 mg/daily. The decision to switch antiplatelet therapy to clopidogrel with either 300 mg LD or 600 mg LD at 12 h was left to the discretion of the treating physician. The primary outcome was a composite of an efficacy endpoint major adverse cardiac and cerebrovascular events (MACCEs) and a safety endpoint Bleeding Academic Research Consortium scale (BARC) (≥1). There were no differences in our composite clinical endpoint of MACCE between the two strategies, with one event occurring in each group. One patient in each group had myocardial infarction due to stent thrombosis, and the patient in the 300 mg switching group died due to stent thrombosis. No difference between the two arms was observed in terms of BARC bleeding criteria. This study showed that among USAP patients undergoing PCI, switching to clopidogrel with 300 mg LD showed no significant difference compared to 600 mg clopidogrel LD. Ticagrelor LD in ad hoc PCI and de-escalation to clopidogrel with 300 mg LD could translate to lower costs for patients with USAP without compromising safety and efficacy.

RESUMO

Background and objectives: In this study, we aimed to evaluate whether the systemic immune-inflammation index (SII) has a prognostic value for major adverse cardiac events (MACEs), including stroke, re-hospitalization, and short-term all-cause mortality at 6 months, in aortic stenosis (AS) patients who underwent transcatheter aortic valve implantation (TAVI). Materials and Methods: A total of 120 patients who underwent TAVI due to severe AS were retrospectively included in our study. The main outcome of the study was MACEs and short-term all-cause mortality at 6 months. Results: The SII was found to be higher in TAVI patients who developed MACEs than in those who did not develop them. Multivariate Cox regression analysis revealed that the SII (HR: 1.002, 95%CI: 1.001-1.003, p < 0.01) was an independent predictor of MACEs in AS patients after TAVI. The optimal value of the SII for MACEs in AS patients following TAVI was >1.056 with 94% sensitivity and 96% specificity (AUC (the area under the curve): 0.960, p < 0.01). We noted that the AUC value of SII in predicting MACEs was significantly higher than the AUC value of the C-reactive protein (AUC: 0.960 vs. AUC: 0.714, respectively). Conclusions: This is the first study to show that high pre-procedural SII may have a predictive value for MACEs and short-term mortality in AS patients undergoing TAVI.

RESUMO

OBJECTIVE: To investigate whether inflammation based scores including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR) and monocyte to high-density lipoprotein cholesterol (HDL-C) ratio (MHR) predict the slow flow (SF)/no-reflow (NR) phenomenon comparatively in patients with non-ST-elevated Myocardial Infarction (NSTEMI) undergoing percutaneous coronary intervention (PCI). METHODS: Current study is retrospective designed and includes 426 NSTEMI patients (mean age of 56.8 ± 11.4 years). The patients were grouped into non slow flow/no-reflow and slow flow/no-reflow groups according to postintervention thrombolysis in myocardial infarction flow grade. RESULTS: The slow flow/no-reflow group had significantly higher MHR and lower LMR values than the non slow flow/no-reflow group (P < 0.01 and P < 0.01, respectively). Lower LMR [odds ratio (OR): 0.659, P < 0.01] and higher MHR (OR: 1.174, P = 0.04) were independent predictors of slow flow/no-reflow phenomenon in model 1 and 2 multivariate analyses, respectively. Furthermore, left ventricular ejection fraction (LVEF) (OR: 0.934, P = 0.01; OR: 0.930, P < 0.01), smoking (OR: 2.279, P = 0.03; OR: 2.118, P = 0.04), Syntax score (1.038, P = 0.04; 1.046, P = 0.01) and high thrombus grade (OR: 7.839, P < 0.01; OR: 8.269, P < 0.01), independently predicted the slow flow/no-reflow development in both multivariate analysis models, respectively. The predictive performance of LMR and MHR was not different (P = 0.88), but both predictive powers were superior to NLR (P < 0.01 and P = 0.03, respectively). CONCLUSION: The MHR and LMR may be useful inflammatory biomarkers for identifying high-risk individuals for the development of slow flow/no reflow in NSTEMI patients who underwent PCI.

RESUMO

OBJECTIVES: The inter-arm systolic blood pressure difference (IASBPD) is closely related to cardiovascular mortality and morbidity. The SYNTAX score indicates the extent and complexity of coronary artery disease, which are determined by coronary angiography. The aim of our study is to examine the relationship between the IASBPD (which is easily calculated in routine practice) and the SYNTAX score. METHODS: 104 patients were included in this cross-sectional study. The IASBPD was calculated by blood pressure measurements obtained simultaneously from both arms. The SYNTAX score was calculated by coronary angiography. RESULTS: Patients were divided into two groups: those with a high SYNTAX score (≥20) and those with a low SYNTAX score (<20). The mean IASBPD values were significantly higher in the group with a high SYNTAX score (≥20) (p<0.001). The patients with IASBPD≥10 were more likely to have a high SYNTAX score compared to the patients with IASBPD<10 (p<0.001). Multiple logistic regression analysis revealed that only the IASBPD values were found to be independently associated with high SYNTAX score (OR: 1.717 (CI: 1.307-2.257), p<0.001). CONCLUSION: The IASBPD values obtained by only blood pressure measurements are closely related to the extent of coronary artery disease.

RESUMO

INTRODUCTION: Usage of the Perclose ProGlide® (PP: Abbott Laboratories, Chicago, IL, USA) closure device is becoming increasingly prevalent during percutaneous endovascular aortic repair (EVAR) and transcatheter aortic valve implantation (TAVI). The respective conditions treated via these procedures, abdominal aortic aneurysm and aortic valve stenosis, share risk factors but are two different physiopathological problems. AIM: Our aim was to compare the complication and success rates of PP closure device use in patients undergoing EVAR and TAVI. MATERIALS AND METHODS: A total of 74 patients, including 58 undergoing TAVI and 16 undergoing EVAR, were analysed in our study. RESULTS: Of the TAVI patients treated using the PP closure device, two (3.4%) had access to site-related bleeding complications and two (3.4%) experienced device failure. Of the EVAR patients who received the PP closure device, three (18.8%) had bleeding complications and three (18.8%) experienced device failure. CONCLUSION: Due to the underlying diffuse aortic wall pathology, the success rate of PP closure device use was lower and the complication rate of PP closure device was higher in the EVAR group versus the TAVI group.

RESUMO

BACKGROUND: The neutrophil to lymphocyte ratio (NLR), has been proposed as potential indicator of cardiovascular events. Our aim was to determine the relationship between NLR and development of myocardial injury after non-cardiac surgery (MINS). METHODS: This observational cohort study included 255 consecutive noncardiac surgery patients aged ≥45 years. Electrocardiography recordings and high sensitivity cardiac troponin T (hscTnT) levels of the patients were obtained for a period of 3 days postoperatively. RESULTS: MINS was detected in 30 (11.8%) patients using the cut-off level of ≥14 ng/L for hscTnT. In the MINS group NLR (3.79 ± 0.7 vs. 2.69 ± 0.6, p < 0.000) values were higher than non-NLR group. The NLR to be independently associated with the development of MINS (OR: 11.690; CI: 4.619-29.585, p < 0.000). CONCLUSIONS: NLR seems to be a simple, easy and cheap tool to predict the development of MINS in patient undergoing non-cardiac surgery.

RESUMO

BACKGROUND: Subclinical hypothyroidism is the most common thyroid dysfunction in the general population. The relationship between overt thyroid dysfunction and hypertension is generally understood. Besides high blood pressure, non-dipper hypertension is known to increase cardiovascular risk. Our aim is to investigate daily blood pressure changes and the frequency of non-dipping patterns in patients with subclinical hypothyroidism. METHODS: Forty-nine patients without hypertension with subclinical hypothyroidism were compared with 50 healthy sex- and age-matched controls using ambulatory blood pressure monitoring. RESULTS: Thyroid-stimulating hormone (TSH) levels were significantly higher in the subclinic hypothyroidism group, and there was no difference between free triiodothyronine (FT3) and free thyroxine (FT4) levels which could be predicted as a result of the study design. Levels of mean diastolic, daytime diastolic, nighttime diastolic and nighttime systolic blood pressure were significantly higher in the subclinic hypothyroidism group (p = 0.001 for mean, daytime and nighttime diastolic and p = 0.01 for nighttime systolic). Diastolic non-dipping occurred more frequently in the subclinic hypothyroidism group [subclinical hypothyroidism group 24 patients (49%), control group 13 patients (26%), p = 0.01]. On multivariate analysis, subclinical hypothyroidism was independently associated with diastolic non-dipping (95% confidence interval 1.162-8.053, odds ratio 1.182, p = 0.024). CONCLUSIONS: Our study found that both the frequency of diastolic non-dipping pattern and diastolic blood pressure increase with subclinical hypothyroidism. Therfore, it would appear that searching for non-dipping pattern can add valuable information for patients with subclinical hypothyroidism.

RESUMO

BACKGROUND: Rheumatic mitral valve stenosis (RMVS)-induced left atrial thrombus (LAT) and embolic complications may have clinically devastating consequences. Stasis in the left atrium induced by valvular obstruction is a major factor in the development of thrombus. However, the development of thrombus may not be solely associated with stasis, as it is known that the inflammatory process increases the tendency for thrombosis. The study aim was to examine the relationship between the neutrophil-to-lymphocyte ratio (NLR), an indicator of inflammation, and the existence of LAT. METHODS: A total of 313 consecutive patients with RMVS and mitral valve area (MVA) <2 cm2 was included in this cross-sectional study. Patients were allocated to two groups with or without LAT using transthoracic and transesophageal echocardiography. Routine biochemical analyses and electrocardiographic examinations were also carried out. The NLR was calculated utilizing blood count analysis. RESULTS: The presence of LAT was identified in 78 RMVS patients (24.9%). No significant differences in terms of age, gender, body mass index were found between the groups with and without LAT. On echocardiographic examination, a higher mean gradient and left atrial diameter, as well as a smaller MVA, were determined in patients with LAT (p<0.001). In those patients with LAT, higher C-reactive protein levels and higher leukocyte and neutrophil counts (p <0.001) and lower lymphocyte counts were noted (p = 0.001). The NLR was shown to be higher in patients with LAT (p <0.001). Multivariate regression analysis showed that the relationship between LAT and a high NLR continued independently (OR 5.3; 95% CI 2.9-9.4; p <0.001). CONCLUSIONS: The NLR is an easily obtained, low-cost and easily repeated parameter that seems effective for identifying RMVS patients who are at high risk of developing LAT.

RESUMO

OBJECTIVE: Rheumatic carditis-induced mitral valve disease is associated with a chronic inflammatory process. The close relationship between inflammation and prothrombotic processes is known. Our goal was to examine the relationship between the presence of left atrial (LA) thrombus in patients with rheumatic mitral valve stenosis (RMVS) and platelet-to-lymphocyte ratio (PLR), which is an inflammatory marker. METHODS: This cross-sectional study included 351 consecutive patients diagnosed with RMVS upon presentation to the cardiology polyclinic. All patients were evaluated using transthoracic and transesophageal echocardiography and were divided into 2 groups: those with and without LA thrombus. In addition to echocardiographic and biochemical parameters, PLR was compared between the groups. Student's t-test, Mann-Whitney U test, logistic regression analysis, and receiver operating characteristic (ROC) curve analysis were used for statistical analysis. RESULTS: No significant differences in terms of age, gender, body mass index, and comorbidities were found between the groups with and without LA thrombus. In the group with LA thrombus, higher red cell distribution width, mean platelet volume, and platelet count and lower lymphocyte count were detected. In addition, C-reactive protein levels were significantly higher in the LA thrombus group (4.7 vs. 2.7 mg/L, p<0.001). PLR was significantly higher in patients with thrombus than in those without (133±38 vs. 119±31, p=0.001). Higher PLR was identified as independently associated with the presence of LA thrombus (odds ratio: 1.03, 95% confidence interval: 1-1.06, p=0.016). CONCLUSION: Higher PLR was detected in the LA thrombus group of patients with RMVS.

RESUMO

BACKGROUND: Atrial fibrillation (AF) frequently accompanies heart failure (HF), and causes exacerbation of symptoms and treatment failure in such patients. Vitamin D was recently suggested to be an important mediator of cardiovascular disease, including HF. OBJECTIVES: The aim of this study was to evaluate the relationship between vitamin D deficiency and AF in patients with chronic HF. MATERIAL AND METHODS: The study included 180 chronic HF patients that were divided into 2 groups based on having sinus rhythm [AF (-) group] or chronic AF [AF (+) group]. Vitamin D status was assessed via measurement of the serum 25-hydroxyvitamin D (25[OH]D) concentration. RESULTS: Mean age of the patients was 66 ± 8.7 years and 53.9% were male. There weren't any significant differences in age, gender, body mass index, etiology or chronic HF stage between the 2 groups. The vitamin D level in the AF (+) group was significantly lower than in the AF (-) group (11.05 ng/mL vs. 20 ng/mL, p < 0.001) and the parathyroid hormone level was significantly higher in the AF (+) group (76.7 vs. 55 pq mL, p < 0.001). The left atrium to body surface area ratio (LA/BSA) was significantly higher in the AF (+) group (45.03 mm/m2 vs. 42.05 mm/m2, p < 0.01). Independent predictors (based on multiple regression) of AF were vitamin D level (OR = 0.854, 95% CI: 0.805-0.907, p < 0.001) and LA/BSA ratio (OR = 1.077, 95% CI: 1.003-1.156, p < 0.05). The optimal vitamin D cut-off value for the prediction of AF was 16.50 ng/mL, with a sensitivity of 76.0% and specificity of 65.5% (AUC = 0.75, 95% CI: 0.67-0.82). CONCLUSIONS: A low plasma vitamin D concentration was strongly associated with AF in patients with chronic HF.

RESUMO

BACKGROUND: Myocardial injury after non-cardiac surgery (MINS) is closely related to increased cardiovascular mortality. AIM: To evaluate the relationship between MINS and interarm systolic blood pressure difference (IASBPD), which has previously been shown to correlate with the frequency of cardiovascular events and arterial arteriosclerotic processes. METHODS: This observational, single-centre cohort study included 240 consecutive noncardiac surgery patients aged ≥ 45 years. Simultaneous blood pressure recordings were taken preoperatively and IASBPD was calculated. Patients' electrocardiography recordings and high sensitivity cardiac troponin T (hscTnT) levels were obtained for a period of three days postoperatively. RESULTS: Postoperatively, 27 (11.3%) patients were found to have MINS when hscTnT ≥ 14 ng/L was taken as a cut-off value. IASBPD > 10 mm Hg was found in 44 (18.3%) patients. When IASBPD was accepted to be a continuous variable, there was a higher IASBPD value in the MINS group (9.4 ± 5.0 vs. 4.5 ± 3.8, p < 0.000). When patients were grouped as those having IASBPD > 10 mm Hg and those not, exaggerate IASBPD was found to be more frequent in patients developing MINS (16 [59.3%] vs. 28 [13.1%], respectively, p < 0.000). Multiple logistic regression analysis found IASBPD > 10 mm Hg to be independently associated with the development of MINS (OR: 30.82; CI: 9.14-103.98; p < 0.000). Receiver operating char-acteristic curve analysis showed that the optimal IASBPD cut-off value for predicting MINS was 11.5 mm Hg, with a sensitivity of 61.0% and specificity of 89.1% (AUC = 0.79; 95% CI 0.71-0.87). CONCLUSIONS: Increased IASBPD is closely related to development of MINS. The preoperative measurement of blood pressure from both arms may be an important and easy to use clinical tool in determining cardiovascular risk.

RESUMO

OBJECTIVE: Recent studies have shown that epicardial adipose tissue (EAT) thickness is increased in patients with hypertension. In this study, we aimed to investigate the relation of EAT thickness with resistant hypertension (RHT). PARTICIPANTS AND METHODS: Study participants (n=150) were classified into three groups according to their office and ambulatory blood pressure measurements: RHT (n=50), controlled hypertension (CHT, n=50), and normotension (NT, n=50). All patients underwent a transthoracic echocardiographic examination to measure EAT thickness. RESULTS: Clinical and biochemical characteristics of the groups were similar, except the CRP level, which was significantly increased in hypertensive patients compared with patients with NT (P<0.001). EAT thickness differed significantly between groups (P<0.001). The highest values were obtained in the RHT group (4.64±1.24 cm), followed by the CHT (3.3±0.82 cm) and NT (2.6±0.76 cm) groups. Multivariate analysis indicated age, physical activity level, and EAT thickness as independent predictors of RHT. The optimal cut-off value of EAT thickness for detection of RHT was found to be 3.42 cm, with a sensitivity and specificity of 82 and 77%, respectively (AUC=0.87, 95% confidence interval 0.81-0.92, P<0.000). CONCLUSION: EAT can be effective on blood pressure by several mechanisms. In this study, for the first time in the literature, the association of EAT with RHT is reported.
