Score-2 in heavy smokers: are we underestimating the risk?

Abstract Background The shared diagnostic decision-making process in patients with atypical chest pain is challenging, especially when functional tests are negative. SCORE2 (1) can help in making decisions. In this score, the risk is assessed based on geographical origin, age, sex, current smoking, systolic blood pressure, cholesterol values. However, it does not take into account the quantity of cigarettes smoked but only the current binary value, yes or no. In our study we wanted to evaluate the impact of smoking on prognosis, considering the number of cigarettes smoked and in particular focusing on heavy smokers. Methods In the last 15 years we evaluated 3,588 outpatients aged >35 years (average 64±9, women 55%) for the presence of stable chest pain. We excluded 290 patients who had ECG changes compatible with recent ischemia, history of myocardial infarction or any other major cardiovascular event, evidence of heart failure, left ventricular dysfunction, or cardiomyopathies. In the other 3,298 cases we applied the traditional classification of typical, atypical angina and non-anginal pain. A functional test was performed in all patients. In 2,774 patients with atypical chest pain and negative functional test we evaluated the extent of cardiovascular risk based on SCORE2 and the number of cigarettes currently smoked. One year follow-up was carried out to evaluate vital status and any fatal and non-fatal cardiovascular events. Results Table 1 shows the events in patients classified according to the degree of cardiovascular risk of SCORE2 and in heavy smokers (≥ 20 cigarettes per day) aged <70 years as a cathegory in itself. In moderate smokers (<20 cigarettes/day) of any age, the risk was considered binary as in the conventional assessment. Tables 2 and 3 show the risk stratification in male and female patients. SCORE2 is unable to intercept the extremely high risk of heavy smokers aged <70 years. This happens both in males, considered at moderate risk in 76% of cases but with a rate of fatal events of 2.4% and as many non-fatal events, both in women with a risk considered moderate in 80% of cases but with a 12% rate of fatal events (as seen in Table 1). Conclusions SCORE2 does not consider the quantity of cigarettes smoked per day, so if we rely on it heavy smokers seem to have a moderate risk. On the contrary, based on our analysis, they all have an extremely high risk, regardless of other risk factors, and in any case higher than non-smoking or moderately smoking patients. Especially heavy smoking women aged <70 years with atypical chest pain and negative functional tests have an extreme risk of fatal cardiac events (12% at one year). Probably these patients (male and female), regardless of the outcome of functional tests, should be sent for an anatomical evaluation for the detection of high-risk stenosis, as well as firmly urged to improve lifestyles and treat risk factors .

Multi-centre post-mortem study on the use of coronary inflammation in CCTA to improve the diagnosis of the coronary related cause of death with histopathology validation

Abstract Background/Introduction A limitation of post-mortem computed tomography (PMCT) is the diagnostic accuracy of coronary related death, which constitute majority of investigations. Measurements using coronary inflammation with fat attenuation index (FAI) Score, clinical risk factors and coronary plaque metrics from CCTA to predict fatal cardiac events (AI-Risk) in living patients has not been used in post-mortem setting. Purpose This study investigates two new techniques to aid the diagnosis of coronary related death in the post-mortem setting: (1) minimally invasive interventional technique to perform PMCT; (2) diagnostic accuracy of FAI-assisted PMCT with histopathology validation. Method Adults with sudden death of unknown cause <48 hours from death were included. Ultrasound guided femoral access to deliver guidewire to the aortic root (Figure 1A), followed by inflation of aortic occlusion balloon and injection of contrast for angiogram. A cardiac radiologist performed the coronary and FAI analysis (1B &C). Two experienced radiologists reported the cause of death without/with aid of FAI score results. The technique was introduced at a second PMCT centre. Results PMCT analysis of 37 participants (27 males, 10 females, age range 42-98) – 15 minimally invasive PMCT, and 22 PMCT from previous study showed FAI score (1D) and AI-Risk (1E) were significantly higher in participants who had coronary related death vs non-coronary related causes. In the receiver operating characteristic (ROC, 1F) analysis, thresholding at 42% for AI-Risk and 34 for Mean FAI score, was able to detect all 18 true positives, 2 false positives (1xpulmonary embolism, and 1xdual pathology of ruptured abdominal aneurysm with severe coronary artery disease; these cases showed high FAI score and AI-Risk), and all true negatives. Both radiologists identified 17/18 coronary related death. There were 5 cases of false positives for coronary related death in Radiologist 1 (3 years’ experience); 8 false positives in Radiologists 2 (10 years’ experience). In non-coronary related deaths, Radiologist 1 identified 14/19 true negative cases, and Radiologist 2 identified 11/19 true negative cases. In all the false positive and negative cases, the radiologists’ diagnostic confidence level was either possible, or unascertain. With the aid of FAI score results, all the true coronary related deaths were identified and no false negative case. This method was introduced at a second centre with 108 PMCTs analysed. There were 40 cases of non-coronary death, and 68 cases of coronary related death on PMCT (imaging diagnosis only). In the non-coronary group, FAI-score assisted results showed 100% concordance. In the coronary group, there was 10% dis-concordance (7/68). Conclusion Minimally invasive PMCT with FAI score-assisted diagnosis has the potential to increase the diagnostic confidence and accuracy of coronary-related cause of death.

Strain rate during isovolumic relaxation as a prognostic biomarker for long-term cardiovascular morbidity and mortality: an exploratory study on a general population.

Left ventricular (LV) strain rate (SR) during early relaxation correlates with LV filling pressures and has been assessed as a prognostic biomarker in several cardiac diseases. Conversely, even though LV SR during isovolumic relaxation (SRIVR)is more strongly related to invasive measurements of LV diastolic function, to date, studies on the role of SRIVR in the long-term prognosis assessment are lacking. Thus, the goal of this study was to assess the potential additive prognostic value of SRIVR on top of conventional cardiovascular risk factors in a general population. 657 subjects (mean age 51.6y; 47.6% males) were included in this study and, besides clinical and standard echocardiographic assessment, tissue Doppler imaging (TDI)-based SR was measured during IVR (SRIVR), early diastole (SRe), and atrial contraction (SRa) in the mid-segment of the inferior, inferolateral, lateral, and septal wall of the LV. During the follow-up period (median 12.1years), the total number of major adverse cardiac events was 85 (13.4%). Overall, after adjustment for known cardiovascular risk factors and important echocardiographic indices in a multivariable-adjusted Cox regression model, SRIVR of the inferolateral wall (SRIVRinflat) remained an independent predictor of fatal and nonfatal cardiac events (HR: 1.49, p = 0.016), along with GLS (HR: 1.35, p = 0.027), age (HR: 1.09, p < 0.001), and male sex (HR: 2.06, p = 0.037). None of SRIVR measured in the other myocardial walls were associated with cardiac outcome. SRIVRinflat predicted adverse outcome in the general population, on top of conventional cardiovascular factors. However, its incremental value as a prognosticator remained limited.

Факторы и уровень суммарного сердечно-сосудистого риска у населения северо-востока России

In northern regions, cardiovascular pathology tends to be more aggressive, is likely to occur at a young age already and often results in disability and even mortality among people who have not yet reached the retirement age. The aim of this study was to assess the structure and age-specific dynamics of basic factors able to cause cardiovascular diseases in men living in northern regions and the total cardiovascular risk. We conducted a one-center experimental cross-sectional comparative one-sample study of 116 men living in the north of the Magadan region. The complex study program included questioning, anthropometric examination, laboratory biochemical tests and molecular-genetic screening of candidate genes of essential hypertension (AGT (rs 4762), AGTR1 (rs5186), ADD1 (rs4961), NOS3 (rs2070744), and АСЕ (rs4340)). Genotyping was performed using real-time polymerase chain reaction. The total cardiovascular risk was calculated using the SCORE scale. The structure of basic risk factors that can cause cardiovascular diseases in men in the Magadan region includes both modifiable (smoking, obesity, essential hypertension, and dyslipidemia) and non-modifiable ones (climatic-geographic and genetic risk factors) in various age groups. With age, risk factors exert stronger influence on each other thus aggravating the clinical course of cardiovascular diseases and increasing risks of fatal cardiac events. This is especially important for northern regions where people are exposed to such non-modifiable risk factors as extreme climate. Moderate risk of cardiovascular diseases (according to the SCORE scale) was established for all men living in the North already at a young age. Therefore, a key task is to develop a strategy for active prevention of cardiovascular pathology that covers public at large starting from younger age groups.

Resistant hypertension and the risk of major adverse cardiac and cerebrovascular events in outpatients

Objective: To investigate the prevalence and associated risk of cardiovascular event of resistant hypertension in treated outpatients. Methods: This study was a nationwide multi-center prospective cohort study. The participants were treated outpatients enrolled in the China Nationwide Ambulatory and Home Blood Pressure Registry study of 42 hospitals in 19 provinces across the country from August 2009 to October 2017. Apparent resistant hypertension was defined as uncontrolled office blood pressure (≥140/90 mmHg, 1 mmHg=0.133 kPa) in spite of the use of three antihypertensive drugs or controlled office blood pressure (<140/90 mmHg) with four antihypertensive drugs or more. Subjects diagnosed with uncontrolled office blood pressure were further subdivided as pseudo-resistant hypertension and true resistant hypertension based on 24 h ambulatory blood pressure monitoring. The primary endpoint was fatal and non-fatal cardiovascular and cerebrovascular events, which was a composite endpoint consisting of cardiovascular and cerebrovascular death, ischemic and hemorrhagic stroke, myocardial infarction, coronary artery revascularization, unstable angina, heart failure, and coronary artery stenosis≥50% confirmed by coronary angiography. Secondary outcomes included fatal and non-fatal stroke or cardiac events. Patients with controlled office blood pressure after taking only 1 or 2 antihypertensive drugs were included as control. Kaplan-Meier survival curves, log-rank test, and Cox proportional risk model were used to evaluate the risk of apparent refractory hypertension in relation to cardiovascular and cerebrovascular prognosis. Results: A total of 2 782 treated hypertensive patients, aged (58.1±12.3) years were enrolled, including 1 403 (50.4%) men. The prevalence of apparent and true resistant hypertension was 15.1% (420/2 782) and 10.5% (293/2 782), respectively. Among patients with apparent resistant hypertension, during a median of 5 years follow-up, the cumulative incidence rate was 28.2, 11.2 and 19.1 per 1 000 person-years for fatal and non-fatal cardiovascular events (n=58), stroke (n=24) and cardiac events (n=40), respectively. The Kaplan-Meier curve and log-rank test showed that those patients with true resistant hypertension, had the highest cumulative incidence rate of fatal and non-fatal cardiovascular events, stroke, and cardiac events. Multivariable Cox regression analyses showed that true resistant hypertension was associated with a significantly higher risk of fatal and non-fatal cardiovascular events (HR=1.73, 95%CI 1.17-2.56, P=0.006) and stroke (HR=2.81, 95%CI 1.53-5.17, P=0.001). Conclusion: Resistant hypertension, especially true resistant hypertension, is associated with a higher risk of fatal and non-fatal cardiac and cerebrovascular events.

BackgroundDavoceticept (ALPN-202) is an Fc fusion of a CD80 variant immunoglobulin domain designed to mediate programmed death-ligand 1 (PD-L1)-dependent CD28 co-stimulation while inhibiting the PD-L1 and cytotoxic T-lymphocyte-associated antigen 4...

Cardiotoxic profiles of CAR-T therapy and bispecific T-cell engagers in hematological cancers

BackgroundChimeric antigen receptor (CAR) T-cell therapy and bispecific T-cell engagers, which redirect T-cells to tumor antigens, have immensely benefitted patients with relapsed/refractory B-cell cancers. How these therapies differ in cardiotoxicity is underexplored. We used the World Health Organization pharmacovigilance database, VigiBase, to compare cardiotoxicity profiles between CD19-targeted CAR-T therapy and blinatumomab (a CD19/CD3-targeted bispecific T-cell engager).MethodsSafety reports in VigiBase were filtered for diffuse large B-cell lymphoma (DLBCL, n = 17,479) and acute lymphocytic leukemia (ALL, n = 28,803) for all adverse reactions. Data were further filtered for patients taking CAR-T therapy or blinatumomab. Reporting odds ratios (ROR) and fatality rates were compared between CAR-T cell products (e.g. tisagenlecleucel and axicabtagene ciloleucel), and between CAR-T therapy and blinatumomab.ResultsTisagenlecleucel is associated with cardiac failure (IC025 = 0.366) with fatality rates of 85.7% and 80.0% in DLBCL and pediatric ALL patients respectively. For DLBCL patients, axicabtagene ciloleucel has greater reporting for hypotension than tisagenlecleucel (ROR: 2.54; 95% CI: 1.28–5.03; p = 0.012), but tisagenlecleucel has higher fatality rates for hypotension than axicabtagene ciloleucel [50.0% (tisagenlecleucel) vs 5.6% (axicabtagene ciloleucel); p < 0.001]. Blinatumomab and tisagenlecleucel have similar fatality rates for hypotension in pediatric ALL patients [34.7% (tisagenlecleucel) vs 20.0% (blinatumomab); p = 0.66].ConclusionsTisagenlecleucel is associated with severe and fatal adverse cardiac events, with higher fatality rates for hypotension compared to axicabtagene ciloleucel in DLBCL patients, but similar hypotension fatality rates compared to blinatumomab in pediatric ALL patients. Effective management necessitates experienced physicians, including cardio-oncologists, skilled in interdisciplinary approaches to manage these toxicities.

REAL-TIME PROCESSING STAGES OF ELECTROCARDIOGRAM SIGNAL: A REVIEW

Signal analysis is a multidisciplinary field that combines various processes to create robust pipelines for automating data analysis. Within the medical field, its application revolves around physiological signals. Electrocardiogram (ECG) signal provides vital information concerning various cardiac conditions affecting the human heart. ECG analysis is a central pillar of medical research with the goal of detecting and preventing potentially fatal cardiac events. This review article aims to provide a comprehensive analysis of real-time processing techniques for electrocardiogram signals. It discusses the different methods and algorithms used for detecting and analyzing ECG signals in real-time, with a focus on their effectiveness and efficiency. Where, it evaluates the use of various techniques such as ECG signal preprocessing (denoising), ECG fiducial points detecting and ECG signal classification. It also highlights the challenges faced in real-time ECG signal processing, such as High-fidelity signal acquisition and noise reduction, and computational efficiency and resource constraints. Furthermore, the article presents an overview of the existing QRS-peak detection strategies, including methods such as Haar wavelet transform, and modified MaMeMi Filter.

Decreased cholinesterase level combined with renal dysfunction and sympathetic denervation associated with increased cardiac mortality in systolic heart failure.

Cardiac mortality in patients with heart failure (HF) is likely to be aggravated by malnutrition, assessed by serum cholinesterase (ChE) level, as well as by kidney dysfunction or impairment of cardiac sympathetic denervation. Their prognostic interactions, however, have not been determined. A total of 991 systolic HF patients were enrolled in our HF database following clinical evaluation including evaluation of the nutrition state and assessment of standardized heart-to-mediastinum ratio (sHMR) of iodine-123-labeled meta-iodobenzylguanidine activity. Patients were followed up for an average of 43 months with the primary endpoint of fatal cardiac events (CEs). The CE patient group had a lower level of ChE, lower estimated glomerular filtration rate (eGFR) and lower late sHMR than those in the non-CE patient group. A five-parameter model with the addition of serum ChE selected in the multivariate logistic analysis (model 2) significantly increased the AUC predicting risk of cardiac events compared with a four-parameter model without serum ChE (model 1), and net reclassification analysis also suggested that the model with the addition of serum cholinesterase significantly improved cardiac event prediction. Moreover, in overall multivariate Cox hazard analysis, serum ChE, eGFR and late sHMR were identified to be significant prognostic determinants. HF patients with two or all of the prognostic variables of serum ChE < 230 U/L, eGFR < 48.8 ml/min/1.73 m2 and late sHMR < 1.90 had significantly and incrementally increased CE rates compared to those in HF patients with none or only one of the prognostic variables. Decreases in cholinesterase level and kidney function further increase cardiac mortality risk in HF patients with impairment of cardiac sympathetic innervation.

Increasing averaging beats improves the test accuracy on Holter-based late potentials in patients with myocardial infarction.

The prevalence of Holter-based late potentials (H-LPs) in cases of fatal cardiac events has increased. Although the noise level of H-LP is higher than that of conventional real-time late potential (LP) recording, a procedure to reduce the noise severity in H-LP by increasing the averaging beats has not been investigated. We enrolled 104 patients with post-myocardial infarction (MI) and 86 control participants. Among the patients, 30 reported sustained ventricular tachycardia (VT), and the remaining 74 had unrecorded VT. H-LPs were measured twice in all groups to evaluate the efficacy of increasing the averaging beats for H-LPs. Thereafter, the average of LP was calculated at 250 (default setting), 300, 400, 500, 600, 700, and 800 beats. Across all three groups (MI-VT group, MI non-VT group, and control group), the noise levels significantly decreased in consonance with the increase in averaging beats. In the MI-VT group, the H-LP positive rate considerably increased with the increase in the averaging beats from 250 to 800 both at night and daytime. In the MI-VT group, the LP parameters significantly deteriorated, which led to a positive judgment corresponding to the increment of the averaged night and day beats. The H-LP positive rates were unchanged in the MI non-VT and control groups, while the LP parameters remained consistent, despite the increased averaging beats in the MI non-VT and control groups. Increasing the calculated averaging beats in H-LPs can improve the sensitivity of predicting fatal cardiac events in patients with MI.

Dissection intramyocardial a rare complication of myocardial infraction: Case report

Intramyocardial dissecting hematoma (IDH) after acute myocardial infarction (MI) is a rare form of subacute cardiac rupture, resulting from hemorrhagic separation of helical fibers within the myocardium, which has been described in most studies as an incomplete cardiac rupture or a specific type of cardiac rupture. The management of myocardial dissection is variable and poorly documented, with clinical outcomes ranging from asymptomatic recovery to fatal cardiac events. We present here a case of myocardial dissection diagnosed by echocardiography.

Non-Conventional Risk Factors: "Fact" or "Fake" in Cardiovascular Disease Prevention?

Cardiovascular diseases (CVDs), such as arterial hypertension, myocardial infarction, stroke, heart failure, atrial fibrillation, etc., still represent the main cause of morbidity and mortality worldwide. They significantly modify the patients' quality of life with a tremendous economic impact. It is well established that cardiovascular risk factors increase the probability of fatal and non-fatal cardiac events. These risk factors are classified into modifiable (smoking, arterial hypertension, hypercholesterolemia, low HDL cholesterol, diabetes, excessive alcohol consumption, high-fat and high-calorie diet, reduced physical activity) and non-modifiable (sex, age, family history, of previous cardiovascular disease). Hence, CVD prevention is based on early identification and management of modifiable risk factors whose impact on the CV outcome is now performed by the use of CV risk assessment models, such as the Framingham Risk Score, Pooled Cohort Equations, or the SCORE2. However, in recent years, emerging, non-traditional factors (metabolic and non-metabolic) seem to significantly affect this assessment. In this article, we aim at defining these emerging factors and describe the potential mechanisms by which they might contribute to the development of CVD.

Incidence and Risk Factors for Development of Cardiac Toxicity in Adult Patients with Newly Diagnosed Acute Myeloid Leukemia.

The incidence of cardiac morbimortality in acute myeloid leukemia (AML) is not well known. We aim to estimate the cumulative incidence (CI) of cardiac events in AML patients and to identify risk factors for their occurrence. Among 571 newly diagnosed AML patients, 26 (4.6%) developed fatal cardiac events, and among 525 treated patients, 19 (3.6%) experienced fatal cardiac events (CI: 2% at 6 months; 6.7% at 9 years). Prior heart disease was associated with the development of fatal cardiac events (hazard ratio (HR) = 6.9). The CI of non-fatal cardiac events was 43.7% at 6 months and 56.9% at 9 years. Age ≥ 65 (HR = 2.2), relevant cardiac antecedents (HR = 1.4), and non-intensive chemotherapy (HR = 1.8) were associated with non-fatal cardiac events. The 9-year CI of grade 1-2 QTcF prolongation was 11.2%, grade 3 was 2.7%, and no patient had grade 4-5 events. The 9-year CI of grade 1-2 cardiac failure was 1.3%, grade 3-4 was 15%, and grade 5 was 2.1%; of grade 1-2, arrhythmia was 1.9%, grade 3-4 was 9.1%, and grade 5 was 1%. Among 285 intensive therapy patients, median overall survival decreased in those experiencing grade 3-4 cardiac events (p < 0.001). We observed a high incidence of cardiac toxicity associated with significant mortality in AML.

Working Alone and/or in Remote Locations: Opportunities to Prevent the Risk of Fatality From Cardiovascular Events in Oil and Gas Extraction Workers.

The aim of the study is to explore personal and work factors related to fatal cardiac events among oil and gas extraction (OGE) workers. The National Institute for Occupational Safety and Health Fatalities in Oil and Gas Extraction database was reviewed to identify fatal cardiac events among OGE workers from 2014 through 2019. A case series design was used to review case files, provide descriptive statistics, and summarize the findings. There were 75 fatalities identified, including 55 (73%) with sufficient information for review. Of the 55 workers, 18 (33%) worked alone. Thirty-six fatal cardiac events (66%) were unwitnessed by a coworker. Toxicology findings suggested some possible exposures to hydrogen sulfide or hydrocarbon gases or vapors. Missing data were common. This study identified the need for cardiovascular disease prevention and treatment, emergency preparedness, lone worker programs, medical screening, and enhanced exposure control in the OGE industry.

Pregnancy-related maternal deaths due to cardiovascular diseases in Japan from 2010 to 2019: an analysis of maternal death exploratory committee data

Objective Cardiovascular disease (CVD) is the leading cause of maternal deaths in high-income countries. This study aimed to assess the characteristics of maternal deaths due to CVDs and the quality of care provided to patients, and to identify elements to improve maternal care in Japan. Methods This descriptive study used the maternal death registration data of the Maternal Deaths Exploratory Committee of Japan between 2010 and 2019. Results Of 445 eligible pregnancy-related maternal deaths, 44 (9.9%) were attributed to CVD. The most frequent cause was aortic dissection (18 patients, 40.9%), followed by peripartum cardiomyopathy (8 patients, 18.2%), and pulmonary hypertension (5 patients, 11.4%). In 31.8% of cases, cardiopulmonary arrest occurred within 30 min after initial symptoms. Frequent symptoms included pain (27.3%) and respiratory symptoms (27.3%), with 61.4% having initial symptoms during the prenatal period. 63.6% of the patients had known risk factors, with age ≥35 years (38.6％), hypertensive disorder (15.9%), and obesity (15.9%) being the most common. Quality of care was assessed as suboptimal in 16 (36.4%) patients. Cardiac risk assessment was insufficient in three patients with preexisting cardiac disease, while 13 patients had symptoms and risk factors warranting intensive monitoring and evaluation. Conclusion Aortic dissection was the leading cause of maternal death due to CVDs. Obstetrics care providers need to be familiar with cardiac risk factors and clinical warning signs that may lead to impending fatal cardiac events. Timely risk assessment, patient awareness, and a multidisciplinary team approach are key to improving maternal care in Japan.

Practical role of preoperative echocardiography in low-risk non-cardiac surgery.

Due to increased needs to reduce non-fatal as well as fatal cardiac events, preoperative echocardiography remains part of routine clinical practice in many hospitals. Data on the role of preoperative echocardiography in low-risk non-cardiac surgery (NCS) other than ambulatory surgeries do not exist. We aimed to investigate the role of preoperative echocardiography in predicting postoperative adverse cardiovascular events (CVEs) in asymptomatic patients undergoing low-risk NCS. The study population was derived from a retrospective cohort of 1,264 patients who underwent elective low-risk surgery at three tertiary hospitals from June 1, 2021, to June 30, 2021. Breast, distal bone, thyroid, and transurethral surgeries were included. Preoperative examination data including electrocardiography, chest radiography, and echocardiography were collected. The primary outcome was a composite of postoperative adverse CVEs including all-cause death, myocardial infarction, cerebrovascular events, newly diagnosed or acutely decompensated heart failure (HF), lethal arrhythmia such as sustained ventricular tachycardia/fibrillation, and new-onset atrial fibrillation within 30 days after the index surgery. Preoperative echocardiography was performed in 503 patients (39.8%), most frequently in patients with breast surgery (73.5%), followed by transurethral (37.7%), distal bone (21.6%), and thyroid surgeries (11.9%). Abnormal findings were observed in 5.0% of patients with preoperative echocardiography. Postoperative adverse CVEs occurred in 10 (0.79%) patients. Although a history of previous HF was an independent predictor of postoperative CVE occurrence (adjusted odds ratio, aOR: 17.98; 95% confidence interval, CI: 1.21-266.71, P = 0.036), preoperative echocardiography did not significantly predict CVE in multivariate analysis (P = 0.097). However, in patients who underwent preoperative echocardiography, the presence of abnormal echocardiographic findings was independently associated with development of CVE after NCS (aOR: 23.93; 95% CI: 1.2.28-250.76, P = 0.008). In particular, the presence of wall motion abnormality was a strong predictor of postoperative adverse CVE. In real-world clinical practice, preoperative echocardiography was performed in substantial number of patients with potential cardiac risk even in low-risk NCS, and abnormal findings were independently associated with postoperative CVE. Future studies should identify patients undergoing low-risk NCS for whom preoperative echocardiography would be helpful to predict adverse CVE.

Electrocardiographic Changes in Patients with Depression after Using Escitalopram for a Short Period

Background&#x0D; Antidepressant drugs are most commonly used for management of depressive disorders. Antidepressant drugs used in psychiatric clinics may affect the electrical activity of the heart which may induce fatal cardiac events.&#x0D; Objectives&#x0D; The purpose of the current study is to reveal the outcomes of escitalopram use for short period of time on the ECG records applying the prolongation of (heart-rate corrected interval for assessing ventricular repolarization) QTc and (corrected JT interval) JTc intervals as a predictor of the negative effects of antidepressants.&#x0D; Methods&#x0D; Twenty-eight patients with major depressive disorder and 20 healthy participants were recruited. Parameters such as weight, height, and blood pressure measurements were determined. Electrocardiographic (ECG) records and echocardiographic records [for ejection fraction (%)] were obtained before administration of escitalopram and after 4 weeks of treatment with daily escitalopram 10 mg. The intervals of JTc and QTc and the voltage criteria (R wave-V5 and S wave-V1) were measured.&#x0D; Results&#x0D; Patients with depression had a significantly prolonged interval of JTc and small-voltage criterion of the ventricles. Escitalopram significantly improves the prolongation in JTc and non-significantly ameliorate the voltage criterion. There is no significant alteration in the parameter of ejection fraction.&#x0D; Conclusion&#x0D; Irregularities in ECG records were observed in patients with major depressive disorder, and treatment with escitalopram for short period is associated with favorable results rather than negative effects. The evaluation of JTc interval in patients with depression is more suitable than QTc measurement in estimation of the effects of escitalopram.

Fragmented QRS on 12-lead electrocardiogram predicts long-term prognosis in patients with cardiac sarcoidosis.

Fragmented QRS (fQRS) on a 12-lead electrocardiogram is a known marker of fatal arrhythmias or cardiac adverse events in ischemic and non-ischemic cardiomyopathy patients. Nonetheless, the association between fQRS and clinical outcomes in patients with cardiac sarcoidosis (CS) remains unclear. Herein, we investigated whether fQRS is associated with long-term clinical outcomes in CS patients. A total of 78 patients who received immunosuppressive therapy (IST) for clinically diagnosed CS were retrospectively examined. Patients were classified into two groups according to the presence (n = 19) or absence (n = 59) of fQRS on electrocardiogram before IST. The primary outcome was the composite event of all-cause death, ventricular tachyarrhythmias (VTs), and hospitalization for heart failure. Results of late gadolinium enhancement on cardiac magnetic resonance imaging were also analyzed. During a median follow-up period of 3.7years (interquartile range: 1.6-6.2years), the primary outcome occurred more frequently in patients with fQRS than in those without (47% vs. 13%, log-rank p = 0.002). Multivariable Cox regression analyses showed that fQRS was an independent determinant of the primary outcome. The incidence of VTs, within 12months of IST initiation, was comparable between the two groups; however, late-onset VTs, defined as those occurring ≥ 12months after IST initiation, occurred more frequently in the fQRS group (21% vs. 2%, log-rank p = 0.002). The scar zone and scar border zone were greater in patients with fQRS than in those without it. In conclusion, our analysis suggests that fQRS is an independent predictor of adverse events, particularly late-onset VTs, in patients with CS.

Prevention of Sudden Death in Sports: A Global and Multidisciplinary Observatory for Scientific Research and Knowledge Transfer (PREMUBID).

The health benefits of sports and exercise training are well known. However, an acute bout of exercise transiently increases the risk of sudden cardiac death (SCD). To minimize the cardiovascular risks of exercise, more insight into the prevention and causes of SCD is needed. The observatory for the prevention of sudden death in sports, PREMUBID, was created with the aim of fostering research to assess the benefits and risks of exercise at different volumes and intensities and to get insight into the underlying mechanisms of potentially cardiac (mal) adaptations. The observatory gathers researchers from a wide range of disciplines working at institutions in Europe and North America. The guiding principles of PREMUBID are to broaden the understanding of SCD in sports, strengthening collaborative research across the globe, and to develop, implement and evaluate robust pre-participation screening and emergency care strategies to further reduce the number of fatal cardiac events in sport events. During the inaugural meeting of the observatory, members and affiliated researchers discussed possibilities to initiate collaborative research projects and to exchange staff and students to share information and practices to prevent SCD. The final goal is to translate the obtained knowledge to understandable messages for the general population and healthcare workers to ensure that the population at large benefits from it. The PREMUBID consortium aims to produce novel knowledge and insights in SCD prevention, in order to maximize the health benefits associated with acute and long-term exercise training.
