RESUMEN

Percutaneous structural interventions are being performed at increased numbers and rare findings or complications occur more frequently. Lipomatous hypertrophy of the interatrial septum (LHIS) is a relatively uncommon finding on transthoracic echocardiogram (TTE). The major challenge is the difficulty in performing transseptal puncture. We aimed to report the difficulties that were experienced during the left atrial appendage (LAA) closure in a case with an extreme form of LHIS.

RESUMEN

Background: Pacing-induced cardiomyopathy (PICM) occurs as a result of high-burden right ventricular (RV) pacing, which usually develops in patients with complete atrioventricular (AV) block. There is a paucity of data on the association between PICM and pre-implantation left ventricular mass index (LVMI). Thus, the purpose of this study was to analyze the influence of LVMI on PICM in patients who had dual chamber permanent pacemakers (PPMs) implanted secondary to complete AV block. Methods: Overall, 577 patients with dual chamber permanent pacemakers (PPMs) were classified into three tertiles according to their pre- implantation LVMI. The average follow-up period was 57 ± 38 months. The baseline characteristics, laboratory and echocardiographic variables were compared between the tertiles. PICM was defined as a ≥ 10% drop in left ventricular ejection fraction (LVEF) from pre-implantation with a resultant LVEF < 50%. PICM occurred in 42 (7.2%) patients. The independent predictors of PICM development, as well as the impact of LVMI on PICM, were investigated. Results: After controlling for confounding baseline variables, the tertile with the greatest LVMI had a 1.8 times higher risk for the development of long-term PICM compared with the tertile with the lowest LVMI, which was accepted as the reference group. A receiver operating characteristic curve analysis revealed that the best LVMI cut- off value for predicting long-term PICM was 109.8 g/m2 with 71% sensitivity and 62% specificity (area under curve: 0.68; 95% confidence interval: 0.60-0.76; p < 0.001). Conclusions: This investigation revealed that pre-implantation LVMI had a prognostic role in predicting PICM in patients with an implanted dual chamber PPM due to complete AV block.

RESUMEN

BACKGROUND: Pro-inflammatory pathways play an important role in the follow-ups of patients with intracardiac defibrillators (ICDs) for heart failure (HF) reduced with ejection fraction (HFrEF). A newly defined index - the systemic immune-inflammation index (SII)-has recently been reported to have prognostic value in patients with cardiovascular disease. This study's aim is to evaluate the SII value regarding its association with long-term mortality and appropriate ICD therapy during a 10-year follow-up. METHODS: This retrospective study included 1011 patients with ICD for HFrEF. The SII was calculated as the neutrophil-to-lymphocyte ratio × total platelet count in the peripheral blood. The study population was divided into two groups according to the SII's optimal cut-off value to predict long-term mortality. The long-term prognostic impact of SII on these patients was evaluated regarding mortality and appropriate ICD therapy. RESULTS: The patients with a higher SII (≥1119) had significantly higher long-term mortality and appropriate ICD therapy rates. After adjustment for all confounding factors, the long-term mortality rate was 5.1 for a higher SII. (95% CI: 2.9-8.1). The long-term appropriate ICD therapy rate was 2.0 for a higher SII (95% CI: 1.4-3.0). CONCLUSION: SII may be an independent predictive marker for both long-term mortality and appropriate ICD therapy in patients with HFrEF.

RESUMEN

BACKGROUND: There is a dearth of data on the predictors of atrial fibrillation (AF) and the association between AF and long-term mortality in octogenarians with dual-chamber permanent pacemakers (PPM). We investigate the occurrence of AF and whether it is associated with overall mortality among octogenarians with dual-chamber PPM implants. METHODS: Three hundred and fifty-four patients with PPM implants were divided into two groups based on their long-term survival status. Baseline characteristics, laboratory variables, and echocardiographic variables were then compared between the groups, and independent predictors of the long-term incidence of AF and mortality were determined. RESULTS: Multivariable Cox regression analysis performed after adjusting for the parameters in univariable analysis revealed that diabetes, urea levels, albumin levels, paced QRS duration, and the frequency of atrial high-rate episodes (AHREs) were independently associated with a long-term risk of AF in octogenarians after having dual chamber PPMs implanted. The left ventricular (LV) ejection fraction, left atrial (LA) anteroposterior diameter, and AHRE + AF (HR 1.498, 95%CI 1.003-2.237, p = 0.048) were independent risk factors for the long-term mortality in octogenarians receiving dual-chamber PPMs implants. CONCLUSION: The occurrence of AF following dual-chamber PPM implantation is a significant prognostic factor in octogenarian patients.

RESUMEN

BACKGROUND: This investigation aimed to examine and compare the predictive value of MADIT-II, FADES, PACE and SHOCKED scores in predicting one-year and long-term all-cause mortality in implantable cardioverter-defibrillator (ICD) implanted patients, 75 years old and older, since there has been an area of uncertainty about the utility and usefulness of these available risk scores in such cases. METHODS: In this observational, retrospective study, 189 ICD implanted geriatric patients were divided into two groups according to the presence of long-term mortality in follow-up. The baseline characteristics and laboratory variables were compared between the groups. MADIT-II, FADES, PACE and SHOCKED scores were calculated at the time of ICD implantation. One-year and long-term predictive values of these scores were compared by a receiver-operating curve (ROC) analysis. RESULTS: A ROC analysis showed that the best cutoff value of the MADIT-II score to predict one-year mortality was ≥ 3 with 87% sensitivity and 74% specificity (AUC 0.83; 95% CI 0.73-0.94; p < 0.001) and that for long-term mortality was ≥ 2 with 83% sensitivity and 43% specificity (AUC 0.68; 95% CI 0.60-0.76; p < 0.001). The predictive value of MADIT-II was superior to FADES, PACE and SHOCKED scores in ICD implanted patients who are 75 years and older. CONCLUSION: MADIT-II score has a significant prognostic value as compared to FADES, PACE and SHOCKED scores for the prediction of one-year and long-term follow-up in geriatric patients with implanted ICDs for heart failure with reduced ejection fraction.

RESUMEN

Idiopathic ventricular arrhythmias (VA) are common and treatment options include anti-arrhythmic drugs (AAD) or catheter ablation. Patients presenting with idiopathic VA which is originating from the left ventricular summit (LVS) poses a particular challenge as the success for catheter ablation is low and AAD's may not be used long-term due to side effects. Ivabradine is an inhibitor of funny current (If) in cardiac pacemaker cells by blocking hyperpolarization-activated cyclic nucleotide-gated (HCN). In the present case, we reported the use of ivabradine in treatment of idiopathic VA which was originated from LVS and was resistant to multiple AAD's and catheter ablation.

RESUMEN

BACKGROUND: Patients with heart failure with reduced ejection fraction (HFrEF) who received implantable cardiac defibrillator (ICD) still remain at high risk due to pump failure and prevalent comorbid conditions. The primary aim of this research was to evaluate the predictive value of C-reactive protein-to-albumin ratio (CAR) for all-cause mortality among patients with HFrEF despite ICD implantation. MATERIALS AND METHODS: Those who were implanted ICD for HFrEF in our institution between 2009 and 2019 were included. Data were extracted from hospital's database. CAR was calculated as ratio of C-reactive protein (CRP) to serum albumin concentration. Patients were grouped into tertiles in accordance with CAR at the time of the implantation. During follow-up duration of 38 [17-77] months, survival times of tertiles were compared by using Kaplan-Meier survival method. Forward Cox proportional regression model was used for multivariable analysis. RESULTS: Thousand and eleven patients constituted the study population. Ischaemic cardiomyopathy was the primary diagnosis in 92.3%, and ICD was implanted for the primary prevention among 33.9% of patients. Of those, 14.5% died after the discharge. Patients in tertile 3 (T3) had higher risk of mortality (4.2% vs 11.0% vs 28.5%) compared with those in other tertiles. Multivariable analysis revealed that when patients in T1 were considered as the reference, both those in T2 and those in T3 had independently higher risk of all-cause mortality. This finding was consistent in the unadjusted and adjusted multivariable models. CONCLUSION: Among patients with HFrEF and ICD, elevated CAR increased the risk of all-cause mortality at long term.

RESUMEN

BACKGROUND AND AIMS: Effective treatment of high low-density lipoprotein cholesterol (LDL-C) levels has been shown to improve cardiovascular outcomes of patients with diabetes mellitus (DM). Herein, we aimed to provide insight to the real-life management of patients with DM in terms of LDL-C goal attainment and adherence to lipid management recommendations. Our objective was also to reveal the reasons of poor LDL-C goal attainment by assessing the perceptions of both physicians and patients. METHODS: We compared the diabetic and non-diabetic patients from the database of a nationwide registry conducted in cardiology outpatient clinics with regard to the demographic characteristics, educational status, comorbidities, medications, laboratory parameters and LDL-C goal attainment. Also, both the patients and attending physicians were surveyed to analyse perceptions and awareness of hypercholesterolemia. RESULTS: Of the 1868 consecutively enrolled patients, 873 (47%) had DM. Proportion of patients on statins was significantly lower in patients with DM (67.8% vs 55.3%; P < .001). The proportion of patients who attained LDL-C targets were lower among the diabetic patients (17.8% vs 15%; P = .06). The most common causes of the discontinuation of statin therapy were negative media coverage about statins (32.1%), and recommendations of physicians to stop the lipid lowering therapy (29.6%). Analysis of the physician survey revealed that the physicians could determine the off-target patients accurately (negative predictive value 98.4%) while the positive predictive value (48.8%) was low. The reasons for not attaining the LDL-C goals in diabetic patients were not prescription of statins (38%) and inadequate (eg low-dose, non-adherent) statin (28.3%) dosages. CONCLUSIONS: In real-life clinical cardiology practice, diabetic patients are far below the recommended LDL-C treatment goals. High-intensity statin treatment in diabetic population is still avoided because of the concerns about polypharmacy and drug interactions. Also, the inertia of physicians and even cardiologists is probably a major cause of refraining of prescription of optimal statin dosages.

RESUMEN

BACKGROUND: Coronavirus disease 2019 (COVID-19) primarily causes lung infection, but recent studies have shown that cardiac involvement is associated with a worse prognosis. OBJECTIVES: We conducted a systematic review and meta-analysis to examine the prevalence of cardiac arrhythmias detected by the electrocardiogram and their relationships with adverse outcomes in patients with COVID-19. METHODS: PubMed and Google were searched for studies that reported on cardiac arrhythmias and/or examined the relationship between arrhythmias and adverse outcomes. RESULTS: Thirty studies with 12,713 participants were included in the systematic review, and 28 studies (n = 12,499) in the meta-analysis. The mean age was 61.3 ± 16.8 years; 39.3% were female. In 25 studies with 7578 patients, the overall prevalence of cardiac arrhythmias was 10.3% (95% confidence interval [CI]: 8.4%-12.3%). The most common arrhythmias documented during hospitalization were supraventricular arrhythmias (6.2%, 95% CI: 4.4%-8.1%) followed by ventricular arrhythmias (2.5%, 95% CI: 1.8%-3.1%). The incidence of cardiac arrhythmias was higher among critically ill patients (relative risk [RR]: 12.1, 95% CI: 8.5-17.3) and among non-survivors (RR: 3.8, 95%, CI: 1.7-8.7). Eight studies reported changes in the QT interval. The prevalence of QTc > 500 ms was 12.3% (95% CI: 6.9%-17.8%). ST-segment deviation was reported in eight studies, with a pooled estimate of 8.7% (95% CI: 7.3% to 10.0%). CONCLUSION: Our meta-analysis showed that QTc prolongation, ST-segment deviation, and various other cardiac arrhythmias were observed in patients hospitalized with COVID-19. The presence of cardiac arrhythmias was associated with a worse prognosis.

RESUMEN

BACKGROUND: The benefit of implantable cardiac defibrillator (ICD) in patients with heart failure and reduced ejection fraction (HFrEF) could be limited in a particular group of patients. Low prognostic nutritional index (PNI) indicates malnutrition and proinflammatory condition. We sought to investigate the value of PNI in predicting long-term mortality among HFrEF patients with ICD. METHODS: Electronic database was searched for identifying patients with HFrEF who were implanted ICD in our institution between 2009 and 2019. Demographic and clinical characteristics of included patients were recorded. PNI was calculated according to the formula: 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (per mm3 ). Patients were divided into the quartiles according to PNI values. Differences between the groups were analyzed by the log-rank test. A forward Cox proportional regression model was used for multivariable analysis. RESULTS: One thousand and hundred patients were included to the study. The underlying heart failure etiology was ischemic and nonischemic in 77.3% and 22.7% of patients, respectively. Mortality rate in Q1 (5.1%) was considered as the reference. In the unadjusted model the mortality rate was 9.5% (hazard ratio [HR] 1.76, 95% confidence interval [95% CI] [0.92-3.38]) in Q2, 10.2% (HR 1.88, 95% CI 0.99-3.58) in Q3, and 39.6% (HR 8.12, 95% CI 4.65-14.17) in Q4. The same trend was consistent in the age- and sex-adjusted, comorbidities-adjusted, and covariates-adjusted models. CONCLUSION: Among patients who were implanted with ICD secondary to HFrEF, lower PNI value predicted all-cause mortality during long-term follow-up. This is the first study demonstrating the value of PNI in this population.

RESUMEN

OBJECTIVES: Previous studies showed that subclinical abnormal left atrial (LA) function could be diagnosed with LA speckle tracking evaluation long before chamber enlargement. Osteoprotegerin (OPG) is a member of the tumor necrosis factor (TNF) receptor superfamily and was recently found to be an indicator for adverse cardiovascular outcomes and a risk factor for new onset atrial fibrillation. The authors hypothesized that OPG values could predict LA mechanical dysfunction and LA remodeling assessed by two-dimensional speckle tracking echocardiography (2D-STE) in patients with hypertension (HT) and diabetes mellitus (DM). METHODS: A single center study was conducted including consecutive patients presenting to the authors' outpatient clinic. Enrolled patients needed to have been treated for HT and DM for at least 1 year. RESULTS: The study included 80 patients (mean age, 57.5 ± 8.3 years). Patients in the impaired LA strain group were older (p = 0.035), had lower low density lipoprotein (LDL) cholesterol (mg/dl) (p = 0.021), and higher OPG (pmol/l) (p = 0.004) values than patients in the normal LA strain group. Univariate logistic regression analysis demonstrated that age (p = 0.039), LDL cholesterol (mg/dl) (p = 0.025), and OPG (pmol/l) (p = 0.008) values were associated with impaired LA strain. Backward multivariate logistic regression analysis showed that LDL cholesterol (mg/dl) (OR: 0.982, CI 95% 0.964-0.999, p = 0.049) and OPG (pmol/l) (OR: 1.438, CI 95% 1.043-1.983, p = 0.027) were independently associated with impaired LA strain. CONCLUSION: In hypertensive and diabetic patients, higher OPG values were associated with impaired LA function assessed by 2D-STE. In this high-risk patient group, serum OPG can be used as a risk predictor for LA mechanical dysfunction.

RESUMEN

BACKGROUND: It is important to identify patients that are at high risk following primary percutaneous coronary intervention (P-PCI) for the treatment of ST-segment elevation myocardial infarction (STEMI). Left ventricular ejection fraction (LVEF) is the most important parameter obtained from transthoracic echocardiography (TTE) for risk stratification. The authors evaluated the value of pulmonary artery pressure (PAP) and left atrial volume index (LAVI) for the prediction of major adverse cardiovascular events (MACE) in patients with STEMI that underwent P­PCI. METHODS: A total of 92 patients that underwent P­PCI for STEMI were included in the study. All patients underwent TTE examination before discharge. The composite primary outcome of the study was all-cause mortality and new onset heart failure (HF) during an 8-year follow-up period. RESULTS: The mean age of patients was 61.6 ± 12.4 years and 15 were female (16.3%). Major adverse cardiovascular events (MACE) defined as all-cause mortality and new onset HF occurred in 30 (41%) patients during a mean of 6 ± 2.7 years of follow-up. In the backward multivariate Cox regression analysis LVEF (odds ratio [OR] = 0.933, 95% confidence interval [CI]: 0.876-0.994, p = 0.031), LAVI (OR = 1.069, 95%CI: 1.017-1.124, p = 0.009), PAP (OR = 1.137, 95% CI: 1.057-1.223, p = 0.001) and creatinine level (OR = 1.730, 95% CI: 1.350-1.223, p = 0.029) were found to independently predict MACE during long-term follow-up. Receiver operating characteristic (ROC) curve analysis was performed, revealing that sPAP >24.5 mm Hg had a sensitivity and specificity of 72 and 66%, respectively; LAVI >31 ml/m2 had a sensitivity and specificity of 72.2 and 83.3%, respectively. CONCLUSION: In patients that underwent P­PCI for the treatment for STEMI, LVEF, LAVI, PAP and creatinine level independently predicted all-cause mortality and new onset HF during long-term follow-up.

RESUMEN

Introduction: It is important to identify those at higher risk for ventricular arrhythmia among hypertensive patients. Epicardial adipose tissue (EAT) leads to electromechanical changes in the heart by endocrine and paracrine effects with cytokines and mediators. Higher amount of EAT carries the risk of QT prolongation. Therefore, we investigated the association between EAT thickness and QTc interval in patients with arterial hypertension. Methods: A total of 230 patients who previously diagnosed with arterial hypertension between February 2019 to March 2020 were included in the study. Patients with atrial fibrillation, U-wave, atrioventricular block, left anterior or posterior fascicular block, right bundle branch block, left bundle branch block, and taking QT-prolonging medication were excluded. The corrected QT (QTc) interval was calculated with Bazzet's formula following the calculated QT interval in the semi-automatic application tool. EAT was measured at the point on the free wall of the right ventricle using transthoracic echocardiography. Results: The mean age was 62.1 ± 11.4 years and 95 (41.3%) of the patients were male. QTc was over 450 ms were considered as the prolonged interval. Both groups were similar in terms of age (p = .862), gender (p = .265) and other demographic characteristics. Left ventricle mass index (LVMI) (82.5 ± 29.5 vs 91.9 ± 32.6 g/1.7.m2, p = .051) and EAT thickness (5.3 ± 2.3 vs 6.6 ± 2.6 mm, p = .001) were higher in the prolonged QTc group. Serum potassium (K) level was lesser in the prolonged QTc group (4.2 ± 0.39 vs 4.1 ± 0.4 mmol/mL, p = .005). Multivariate Cox regression analysis revealed that EAT thickness [OR = 1.227, 95% CI: 1.081-1.393, p = .002] and serum K level [OR = 0.348, 95% CI: 0.157-0.772, p = .009] predicted the prolonged QTc interval, independently. Conclusion: EAT thickness predicted prolonged QTc interval in patients with arterial hypertension. Patients with higher amount of EAT should be followed by closely monitoring to prevent arrhythmic events that may develop in the future. In addition, medications that have a potential effect on QTc interval prolongation may be carefully used in patients with higher EAT thickness.

RESUMEN

A 30-year-old lady was admitted to the hospital with progressive exertional dyspnoea and bradycardia. A complete atrioventricular block was diagnosed using 12­lead electrocardiography and a transthoracic echocardiography revealed a severely impaired left ventricular systolic dysfunction with an ejection fraction of 20%. Following hospitalization, her coronary angiography was normal, so a whole exome sequencing was conducted. The novel Lamin A/C Gene missense mutation c.263C > A,p.Ala88Asp in exon 3 was identified. A CRT-D was implanted due to the high risk of life-threatening ventricular arrhythmias and low potential for left ventricular reverse remodelling. The patient is undergoing follow-ups at the outpatient clinic, showing a 25% improvement in left ventricular ejection fraction during the last visit.

RESUMEN

BACKGROUND: Atrial fibrillation (AF) is the most common preventable cause of stroke. Diagnosis of new AF is frequent after acute ischemic stroke (AIS). We aimed to evaluate the predictive value of the recently developed morphology-voltage-P-wave duration (MVP) ECG risk score for in-hospital and long-term AF diagnosis following AIS. MATERIAL AND METHODS: In this observational investigation, we evaluated the ability of the MVP ECG risk score to predict AF in 266 consecutive patients with AIS. The study population was divided into three groups according to their calculated MVP ECG risk score on admission electrocardiography. The groups were compared in terms of their predictive value for in-hospital and long-term AF diagnosis. RESULTS: After adjustment for confounding baseline variables, MVP ECG risk score 5-6 group had 13.2 times higher rates of in-hospital AF compared to MVP ECG risk score 0-2 group, which was used as the reference group. For long-term follow-up, MVP ECG risk score 5-6 group had 5.2 times higher rates of long-term AF compared to MVP ECG risk score 0-2 group. A ROC analysis showed that the optimal cut-off value of the MVP ECG risk score to predict in-hospital AF was 4 with 78% sensitivity and 76% specificity (AUC: 0.80; 95% CI: 0.64-0.96; p < 0.001), the optimal cut-off value of the MVP ECG risk score to predict long-term AF was 3 with 85% sensitivity and 59% specificity (AUC: 0.81; 95% CI: 0.76-0.86; p < 0.001). CONCLUSION: The MVP ECG risk score, which can be easily calculated from a surface ECG, can be used to guide who needs stricter monitoring for the diagnosis of long-term AF in patients with AIS.

RESUMEN

BACKGROUND: Erectile dysfunction (ED) has been proposed as an early indicator for future coronary and peripheral vascular disease. AIM: We aimed to investigate the longitudinal change in proportion and predictors for ED with changes in erectile function domain (EFD) of the International Index of Erectile Function-15 (IIEF-15) in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PPCI). METHODS: Between December 2018 and June 2019, 286 male patients aged between 40 and 70 years who were treated with PPCI for STEMI were included. The patients were asked to complete the IIEF-EFD form 3 days after the procedure for the evaluation of baseline erectile functions. During follow-up 3 months after the index procedure, the patients were asked to refill the IIEF-EFD form. Both baseline and third-month IIEF-EFD scores were calculated, and the patients were classified into ED severity groups as per the IIEF-EFD scores. A linear mixed model was used to identify predictors of ED at 3 months. OUTCOMES: This study identifies the prevalence and predictors of ED with STEMI who underwent PPCI. RESULTS: The median age was 54 (range 48-61) years. The median IIEF-EFD scores at 3 days and 3 months were 25.5 (range 20.0-27.0) and 22.00 (range 18.25-25.00), respectively. Half of the patients were found to have ED with varying severity as per baseline IIEF-EFD scores. This rate increased to 79% at the 3-month follow-up visit. The IIEF-EFD scores of the patients decreased over time (P < .001). Advanced age (ß = -0.603, se = 0.192, P = .002), presence of three-vessel coronary artery disease (ß = -3.828, se = 0.783, P < .001), and diabetes (ß = -2.934, se = 0.685, P < .001) were found to be inversely associated with the IIEF-EFD scores. CLINICAL IMPLICATIONS: Advanced age, presence of three-vessel disease, and diabetes mellitus are the indicators of sexual rehabilitation needs in patients after STEMI. STRENGTHS & LIMITATIONS: This is the first study investigating the predictor variables for the development of ED after coronary artery disease treatment. The limitations include the lack of evaluation of anxiety and depression and the measurements of testosterone levels. CONCLUSION: The prevalence of ED was high among patients with coronary artery disease, and the frequency of ED increased during 3-month follow-up. Advanced age, three-vessel disease, and diabetes were significant predictors of ED with changes in IIEF-EFD score in patients with STEMI who underwent PPCI. Karabay E, Karsiyakali N, Cinier G, et al.

RESUMEN

BACKGROUND: Interatrial block (IAB) is an electrical conduction delay between the right and left atrium and is associated with some cardiovascular disorders. Arterial stiffness is a useful prognostic marker for cardiovascular events. In the present study, we aimed to investigate the coexistence of increased arterial stiffness and IAB in overweight subjects. METHODS: A total of 110 overweight people were enrolled (56 subjects with IAB, and 54 age- and gender-matched subjects without IAB) into the study. Surface 12-lead standard ECGs were recorded. I.E.M. Mobil-O-Graph ambulatory blood pressure monitor device was used to assess the arterial stiffness. RESULTS: The mean age of the patients was 54.1 ± 11.5 years, and 53.6% were male. PWV and Aix were significantly higher in IAB (+) group than IAB (-) group (9.34 ± 1.5 vs. 7.86 ± 1.3, p < .001; 29.18 ± 11.2 vs. 22.75 ± 10.4, p < .001, respectively), and also, positive linear correlation was observed between arterial stiffness parameters and P-wave duration (r = .758 for PWV; r = .682 for Aix, respectively). CONCLUSION: The present study is the first to focus on evaluating the relationship between the presence of IAB and arterial stiffness in overweight subjects. If there is a coexistence of increased arterial stiffness and IAB in overweight subjects, it should be considered as requiring clinically closer follow-up.

RESUMEN

AIM: Current literature lacks a definitive threshold of idiopathic premature ventricular complex (PVC) burden for predicting cardiomyopathy (CMP). The main objective of the present study was to evaluate relationship between the PVC burden and left ventricular ejection fraction (LVEF). METHOD: This multicenter, cross-sectional study included 341 consecutive patients with more than 1,000 idiopathic PVC in 24 hr of Holter monitoring admitted to the cardiology clinics between January 2019 and May 2019 in the nineteen different centers. The primary outcome was the LVEF measured during the echocardiographic examination. RESULT: Overall, the median age was 50 (38-60) and 139 (49.4%) were female. Percentage of median PVC burden was 9% (IQR: 4%-17.4%). Median LVEF was found 60% (55-65). We used proportional odds logistic regression method to examine the relationship between continuous LVEF and candidate predictors. Increase in PVC burden (%) (regression coefficient (RE) -0.644 and 95% CI -1.063, -0.225, p < .001), PVC QRS duration (RE-0.191 and 95% CI -0.529, 0.148, p = .049), and age (RE-0.249 and 95% CI -0.442, -0.056, p = .018) were associated with decrease in LVEF. This inverse relationship between the PVC burden and LVEF become more prominent when PVC burden was above 5%. A nomogram developed to estimate the individual risk for decrease in LVEF. CONCLUSION: Our study showed that increase in PVC burden %, age, and PVC QRS duration were independently associated with decrease in LVEF in patients with idiopathic PVC. Also, inverse relationship between PVC burden and LVEF was observed in lower PVC burden than previously known.

RESUMEN

Background: YKL-40 (human cartilage glycoprotein 39, chitinase-3-like protein 1) is an inflammatory marker secreted mainly by macrophages and has distinctive roles on extracellular matrix remodeling, macrophage maturation, adhesion, and migration. Despite the presence of robust data suggesting the association of YKL-40 with variety of cardiovascular diseases (CV), there is no study up to date evaluating the role of YKL-40 on the long-term prognosis in patients with hypertension (HT).Methods: A single center, prospective, observational cohort study that included 327 consecutive hypertensive patients which were presented to a cardiology outpatient clinic. Patients were followed up for 7.89 ± 0.12 years. Primary outcome of the study was the occurrence of major cardiovascular outcomes (MACE) defined as all-cause mortality, new onset heart failure (HF), and coronary artery disease (CAD) requiring revascularization.Results: A total of 135 patients constituted the final study population [mean age: 52.4 ± 10.2, female: 63 (46%)]. A total of 28 (20.7%) patients had MACE during the follow up. Cox regression analysis revealed that age (HR: 1.046, 1.016-1.093 CI 95%, p = .026), diabetes (HR: 2.278, 1.026-5.057 CI 95%, p = .043), and YKL-40 level (HR: 1.019, 1.013-1.026 CI 95%, p = .005) significantly predicted MACE. We found that sensitivity and specificity of YKL-40 > 93.5 for predicting MACE was 71.4% and 65%, respectively with an area under curve (AUC) 0.723 (0.617-0.828 CI 95%, p < .001)Conclusion: Elevated serum YKL-40 level predicted MACE in hypertensive patients during a long-term follow up.

RESUMEN

BACKGROUND: Recent studies demonstrated that epicardial fat tissue (EFT) was associated with prevalent AF and recurrences following the catheter ablation. We evaluated the value of EFT for the prediction of advanced interatrial block (a-IAB) in the surface electrocardiography (ECG) among hypertensive patients. METHODS: Patients with prior diagnosis of hypertension (HT) were included in the study. Surface ECG and transthoracic echocardiography (TTE) were performed to each patient. A-IAB was defined as P-wave duration longer than 120 ms with biphasic morphology in the inferior leads. EFT was identified by using TTE and was measured perpendicularly in front of the right ventricular free wall at the end-systole. RESULTS: Between February 2019 and February 2020 245 patients met the eligibility criteria. A-IAB was found among 35 patients and compared to those without IAB, they had increased waist circumference, elevated left ventricular mass index (LVMI) and left atrial volume index (LAVI), lower LDL and increased P wave duration. EFT thickness was higher in patients with a-IAB compared to those without (5.3 ±â€¯2.2 mm vs 7.6 ±â€¯2.4 mm). Multivariable analysis revealed that increased EFT thickness and lower LDL level predicted a-IAB. CONCLUSION: Among patients with prior diagnosis of HT, higher EFT thickness evaluated by TTE predicted the presence of a-IAB on the surface ECG.
