RESUMEN
BACKGROUND: Lower income is associated with high incident cardiovascular disease (CVD) and mortality. CVD is an important cause of morbidity and mortality in cancer survivors. However, there is limited research on the association between income, CVD, and mortality in this population. METHODS: This study utilized nationally representative data from the National Health and Nutrition Examination Survey (NHANES), a cross-sectional survey evaluating the health and nutritional status of the US population. Our study included NHANES participants aged ≥20 years from 2003-2014, who self-reported a history of cancer. We evaluated the association between income level, prevalence of CVD, and all-cause mortality. All-cause mortality data was obtained through public use mortality files. Income level was assessed by poverty-income ratio (PIR) that was calculated by dividing family (or individual) income by poverty guideline. We used multivariable-adjusted Cox proportional hazard models through a backward elimination method to evaluate associations between PIR, CVD, and all-cause mortality in cancer survivors. RESULTS: This cohort included 2,464 cancer survivors with a mean age of 62 (42% male) years. Compared with individuals with a higher PIR tertiles, those in the lowest PIR tertile had a higher rate of pre-existing CVD and post-acquired CVD. In participants with post-acquired CVD, the lowest PIR tertile had over two-fold increased risk mortality (Hazard Ratio (HR) = 2.17; 95% CI: 1.27-3.71) when compared to the highest PIR tertile. Additionally, we found that PIR was as strong a predictor of mortality in cancer survivors as CVD. In patients with no CVD, the lowest PIR tertile continued to have almost a two-fold increased risk of mortality (HR = 1.72; 95% CI: 1.69-4.35) when compared to a reference of the highest PIR tertile. CONCLUSIONS: In this large national study of cancer survivors, low PIR is associated with a higher prevalence of CVD. Low PIR is also associated with an increased risk of mortality in cancer survivors, showing a comparable impact to that of pre-existing and post-acquired CVD. Urgent public health resources are needed to further study and improve screening and access to care in this high-risk population.

AIMS: Although impaired left ventricular (LV) global longitudinal strain (GLS) with apical sparing is a feature of cardiac amyloidosis (CA), its diagnostic accuracy has varied across studies. We aimed to determine the ability of apical sparing ratio (ASR) and most common echocardiographic parameters to differentiate patients with confirmed CA from those with clinical and/or echocardiographic suspicion of CA but with this diagnosis ruled out. METHODS AND RESULTS: We identified 544 patients with confirmed CA and 200 controls (CTRLs) as defined above (CTRL patients). Measurements from transthoracic echocardiograms were performed using artificial intelligence software (Us2.AI, Singapore) and audited by an experienced echocardiographer. Receiver operating characteristic curve analysis was used to evaluate the diagnostic performance and optimal cut-offs for the differentiation of CA patients from CTRL patients. Additionally, a group of 174 healthy subjects (healthy CTRL) was included to provide insight on how patients and healthy CTRLs differed echocardiographically. LV GLS was more impaired (-13.9 ± 4.6% vs. -15.9 ± 2.7%, P < 0.0005), and ASR was higher (2.4 ± 1.2 vs. 1.7 ± 0.9, P < 0.0005) in the CA group vs. CTRL patients. Relative wall thickness and ASR were the most accurate parameters for differentiating CA from CTRL patients [area under the curve (AUC): 0.77 and 0.74, respectively]. However, even with the optimal cut-off of 1.67, ASR was only 72% sensitive and 66% specific for CA, indicating the presence of apical sparing in 32% of CTRL patients and even in 6% healthy subjects. CONCLUSION: Apical sparing did not prove to be a CA-specific biomarker for accurate identification of CA, when compared with clinically similar CTRLs with no CA.

Importance: Drug overdose (OD) is a public health challenge and an important cause of out-of-hospital cardiac arrest (OHCA). Existing studies evaluating OD-related OHCA (OD-OHCA) either aggregate all drugs or focus on opioids. The epidemiology, presentation, and outcomes of drug-specific OHCA are largely unknown. Objective: To evaluate the temporal pattern, clinical presentation, care, and outcomes of adult patients with OHCA overall and according to the drug-specific profile. Design, Setting, and Participants: This cohort study of adults with OHCA in King County Washington was conducted between January 1, 2015, and December 31, 2021. Etiology of OHCA was determined using emergency medical service, hospital, and medical examiner records. Etiology was classified as non-OD OHCA or OD-OHCA, with drug-specific profiles categorized as (1) opioid without stimulant, (2) stimulant without opioid, (3) opioid and stimulant, or (4) all other nonstimulant, nonopioid drugs. Statistical analysis was performed on July 1, 2023. Exposure: Out-of-hospital cardiac arrest. Main Outcomes and Measures: The primary outcome was survival to hospital discharge. The secondary outcome was survival with favorable functional status defined by Cerebral Performance Category 1 or 2 based on review of the hospital record. Results: In this cohort study, there were 6790 adult patients with emergency medical services-treated OHCA from a US metropolitan system. During the 7-year study period, there were 702 patients with OD-OHCA (median age, 41 years [IQR, 29-53 years]; 64% male [n = 450] and 36% female [n = 252]) and 6088 patients with non-OD OHCA (median age, 66 years [IQR, 56-77 years]; 65% male [n = 3944] and 35% female [n = 2144]). The incidence of OD-OHCA increased from 5.2 (95% CI, 3.8-6.6) per 100â¯000 person-years in 2015 to 13.0 (95% CI, 10.9-15.1) per 100â¯000 person-years in 2021 (P < .001 for trend), whereas there was no significant temporal change in the incidence of non-OD OHCA (P = .30). OD-OHCA were more likely to be unwitnessed (66% [460 of 702] vs 41% [2515 of 6088]) and less likely to be shockable (8% [56 of 702] vs 25% [1529 of 6088]) compared with non-OD OHCA. Unadjusted survival was not different (20% [138 of 702] for OD vs 18% [1095 of 6088] for non-OD). When stratified by drug profile, combined opioid-stimulant OHCA demonstrated the greatest relative increase in incidence. Presentation and outcomes differed by drug profile. Patients with stimulant-only OHCA were more likely to have a shockable rhythm (24% [31 of 129]) compared with patients with opioid-only OHCA (4% [11 of 295]) or patients with combined stimulant-opioid OHCA 5% [10 of 205]), and they were more likely to have a witnessed arrest (50% [64 of 129]) compared with patients with OHCA due to other drugs (19% [14 of 73]) or patients with combined stimulant-opioid OHCA (23% [48 of 205]). Patients with a combined opioid-stimulant OHCA had the lowest survival to hospital discharge (10% [21 of 205]) compared with patients with stimulant-only OHCA (22% [29 of 129]) or patients with OHCA due to other drugs (26% [19 of 73]), a difference that persisted after multivariable adjustment. Conclusions and Relevance: In a population-based cohort study, the incidence of OD-OHCA increased significantly from 2015 to 2021, with the greatest increase observed among patients with a combined stimulant-opioid OHCA. Presentation and outcome differed according to the drug-specific profile. The combination of increasing incidence and lower survival among among patients with a opioid-stimulant OHCA supports prevention and treatment initiatives that consider the drug-specific profile.

OBJECTIVES: Patients with congenital heart disease (CHD) are increasingly pursuing pregnancy, highlighting the need for data on late cardiovascular events (more than 6 months after delivery). We aimed to determine the incidence of late cardiovascular events in postpartum patients with CHD and evaluate the accuracy of the existing risk scores in predicting these events. STUDY DESIGN: We identified patients with CHD who delivered between 2008 and 2020 at a tertiary centre and had follow-up data for greater than 6 months post partum. Late cardiovascular events were defined as heart failure, arrhythmia, thromboembolic events, endocarditis, urgent cardiovascular interventions or death. Survival analysis and Cox proportional model were used to estimate the incidence of late cardiovascular events and determine the hazard ratio of factors associated with these events. RESULTS: Of 117 patients, 19% had 36 late cardiovascular events over a median follow-up of 3.8 years. Annual incidence of any late cardiovascular event was 5.7%. Hazards of late cardiovascular events were significantly higher among those with higher Cardiac Disease in Pregnancy Study (CARPREG) II and Zwangerschap bij Aangeboren HARtAfwijking-Pregnancy in Women With Congenital Heart Disease (ZAHARA) risk scores and among patients with prepregnancy New York Heart Association class≥II. C-statistic to predict the late cardiovascular events was highest for ZAHARA (0.7823), followed by CARPREG II (0.6902) and prepregnancy New York Heart Association class≥ II (0.6677). CONCLUSIONS: Currently available risk tools designed for prognostication during the peripartum period can also be used to determine risks of late maternal cardiovascular events among those with CHD. These findings provide important new information for counselling and risk modification.

Heart failure (HF) is a global public health concern that affects millions of people worldwide. While there have been significant therapeutic advancements in HF over the last few decades, there remain major disparities in risk factors, treatment patterns and outcomes across race, ethnicity, socioeconomic status, country and region. Recent research has provided insight into many of these disparities, but there remain large gaps in our understanding of worldwide variations in HF care. Although the majority of the global population resides across Asia, Africa and South America, these regions remain poorly represented in epidemiological studies and HF trials. Recent efforts and registries have provided insight into the clinical profiles and outcomes across HF patterns globally. The prevalence of HF and associated risk factors has been reported and varies by country and region ranges, with minimal data on regional variations in treatment patterns and long-term outcomes. It is critical to improve our understanding of the different factors that contribute to global disparities in HF care so we can build interventions that improve our general cardiovascular health and mitigate the social and economic cost of HF. In this narrative review, we hope to provide an overview of the global and regional variations in HF care and outcomes.

Since the nationally televised cardiac arrest of American National Football League player Damar Hamlin in January 2023, commotio cordis has come to the forefront of public attention. Commotio cordis is defined as sudden cardiac arrest due to direct trauma to the precordium resulting in ventricular fibrillation or ventricular tachycardia. While the precise incidence of commotio cordis is not known due to a lack of standardized, mandated reporting, it is the third most common cause of sudden cardiac death in young athletes, with more than 75% of cases occurring during organized and recreational sporting events. Given that survival is closely tied to how quickly victims receive cardiopulmonary resuscitation and defibrillation, it is crucial to raise awareness of commotio cordis so that athletic trainers, coaches, team physicians, and emergency medical personnel can rapidly diagnose and treat this often-fatal condition. Broader distribution of automated external defibrillators in sporting facilities as well as increased presence of medical personnel during sporting events would also likely lead to higher survival rates.

Advances in breast cancer (BC) treatment have contributed to improved survival, but BC survivors experience significant short-term and long-term cardiovascular mortality and morbidity, including an elevated risk of heart failure with preserved ejection fraction (HFpEF). Most research has focused on HF with reduced ejection fraction (HFrEF) after BC; however, recent studies suggest HFpEF is the more prevalent subtype after BC and is associated with substantial health burden. The increased HFpEF risk observed in BC survivors may be explained by treatment-related toxicity and by shared risk factors that heighten risk for both BC and HFpEF. Beyond risk factors with physiological impacts that drive HFpEF risk, such as hypertension and obesity, social determinants of health (SDOH) likely contribute to HFpEF risk after BC, impacting diagnosis, management and prognosis.Increasing clinical awareness of HFpEF after BC and screening for cardiovascular (CV) risk factors, in particular hypertension, may be beneficial in this high-risk population. When BC survivors develop HFpEF, treatment focuses on initiating guideline-directed medical therapy and addressing underlying comorbidities with pharmacotherapy or behavioural intervention. HFpEF in BC survivors is understudied. Future directions should focus on improving HFpEF prevention and treatment by building a deeper understanding of HFpEF aetiology and elucidating contributing risk factors and their pathogenesis in HFpEF in BC survivors, in particular the association with different BC treatment modalities, including radiation therapy, chemotherapy, biological therapy and endocrine therapy, for example, aromatase inhibitors. In addition, characterising how SDOH intersect with these therapies is of paramount importance to develop future prevention and management strategies.

Pheochromocytomas are catecholamine-producing tumors and a rare cause of sudden cardiac death. We describe the case of a previously healthy 28-year-old man who presented after a ventricular fibrillation out-of-hospital cardiac arrest (OHCA). His clinical investigation, including a coronary evaluation, was unremarkable. A protocolized head-to-pelvis computed tomography (CT) scan was ordered and revealed a large right adrenal mass with subsequent laboratory studies showing markedly elevated urine and plasma catecholamines. This raised suspicion for a pheochromocytoma as the underlying etiology behind his OHCA. He received appropriate medical management, underwent adrenalectomy with subsequent normalization of his metanephrines, and fortunately did not have recurrent arrythmias. This case highlights the first documented case of a ventricular fibrillation arrest as the initial presentation of pheochromocytoma crisis in a previously healthy individual, and how the use of early protocolized sudden death CT scan allowed for the prompt diagnosis and management of a rare cause of OHCA. Learning objective: We review the typical cardiac manifestations of pheochromocytoma and describe the first case of a pheochromocytoma crisis presenting as sudden cardiac death (SCD) in a previously asymptomatic individual. In young patients with unexplained SCD, it is important to consider pheochromocytoma in the differential diagnosis. We also review why an early head-to-pelvis sudden death computed tomography scan protocol may be helpful in the evaluation of patients resuscitated from SCD without an obvious etiology.
RESUMEN
Background With improving survival of patients with single ventricle physiology who underwent Fontan palliation, there is also an increase in the prevalence of overweight and obesity in these patients. This tertiary care single-center study aims to determine the association of body mass index (BMI) with the clinical characteristics and outcomes in adults with Fontan. Methods and Results Adult patients (aged ≥18 years) with Fontan who were managed at a single tertiary care center between January 1, 2000, and July 1, 2019, and had BMI data available were identified via retrospective review of medical records. Univariate and multivariable (after adjusting for age, sex, functional class, and type of Fontan) linear and logistic regression, as appropriate, were utilized to evaluate associations between BMI and diagnostic testing and clinical outcomes. A total of 163 adult patients with Fontan were included (mean age, 29.9±9.08 years), with a mean BMI of 24.2±5.21 kg/m2 (37.4% of patients had BMI ≥25 kg/m2). Echocardiography data were available for 95.7% of patients, exercise testing for 39.3% of patients, and catheterization for 53.7% of patients. Each SD increase in BMI was significantly associated with decreased peak oxygen consumption (P=0.010) on univariate analysis and with increased Fontan pressure (P=0.035) and pulmonary capillary wedge pressure (P=0.037) on multivariable analysis. In addition, BMI ≥25 kg/m2 was independently associated with heart failure hospitalization (adjusted odds ratio [AOR], 10.2; 95% CI, 2.79-37.1 [P<0.001]) and thromboembolic complications (AOR, 2.79; 95% CI, 1.11-6.97 [P=0.029]). Conclusions Elevated BMI is associated with poor hemodynamics and worse clinical outcomes in adult patients with Fontan. Whether elevated BMI is the cause or consequence of poor clinical outcomes needs to be further established.

We present a case of a woman with past medical history notable for mild COVID-19 infection who presented with dyspnea on exertion, then developed progressively worsening exertional desaturations and was found to have a patent foramen ovale (PFO). Extensive cardiopulmonary testing revealed no clear alternate etiology for her symptoms. After much discussion, she underwent successful closure of the PFO with complete resolution of her symptoms and significantly improved exertional desaturation.

We report the case of a 37-year-old transgender patient with a history of orchiectomy on gender-affirming estrogen therapy who was hospitalized with an acute onset of chest pain with a resolution shortly after the presentation. On presentation, the patient had a rapid rise in troponin level and was urgently taken to the cardiac catheterization lab where spontaneous coronary artery dissection was diagnosed and treated with cutting balloon angioplasty and medical management. After a multidisciplinary discussion, the only notable risk factor was estrogen supplementation after gender reassignment surgery. To our knowledge, this is the only report of a male to female transgender patient reported to have spontaneous coronary artery dissection.

OBJECTIVE: This tertiary centre study aims to identify factors associated with adverse outcomes in adult survivors with total cavopulmonary connection (TCPC) Fontan palliation for single ventricle. METHODS: This retrospective review of medical records identified adult (≥18 years) survivors of TCPC Fontan palliation who were followed at a single tertiary centre between 1 January 2000 and 1 July 2019. Adverse outcomes were defined as arrhythmia, pacemaker/implantable cardioverter defibrillator placement, liver cirrhosis, protein losing enteropathy, hospitalisation for heart failure, thromboembolic complication and/or death. RESULTS: 160 adult TCPC patients met the inclusion criteria: 117 (73.1%) extracardiac and 43 (26.9%) lateral tunnel. The median (IQR) duration of follow-up since TCPC palliation was 17.5 (11.8-21.3) years. An adverse outcome occurred in 87 (54.4%) patients. Adverse outcome-free survival rates at 10, 20 and 25 years post TCPC were 89% (95% CI 82% to 93%), 60% (95% CI 50% to 69%) and 24% (95% CI 15% to 35%), respectively. On multivariate analysis, extracardiac Fontan (HR 2.21, 95% CI 1.20 to 4.08, p=0.011) was observed to be an independent risk factor for adverse outcomes after adjusting for age, race, morphology of the systemic ventricle and history of fenestration. CONCLUSIONS: In this single-centre retrospective study of adult survivors of TCPC palliation, extracardiac Fontan was associated with an increased hazard for adverse outcomes. This finding could guide clinicians in developing risk modification strategies and management decisions to improve long-term outcomes in these patients.

BACKGROUND: Pulmonary vein isolation (PVI) with autonomic modulation may be more successful than PVI alone for atrial fibrillation (AF) ablation and may be signaled by changes in sinus rhythm heart rate (HR) post ablation. We sought to determine if a change in sinus rhythm HR predicted AF recurrence post PVI. METHODS: Patients who underwent AF ablation from 2000 to 2011 were included if sinus rhythm was noted on ECG within 90 days pre and 7 days post ablation. Basic ECG interval and HR changes were analyzed and outcomes determined. RESULTS: A total of 1152 patients were identified (74.3% male, mean age 57 ± 11 years). Mean AF duration was 5.2 ± 5.3 years. Paroxysmal AF was noted in 712 (61.8%) of the patients. Mean EF was 61% ± 6%. Sinus rhythm HR was 61 ± 11 pre-ablation and 76 ± 13 bpm post-ablation (27% ± 24% increase, p < .001). The ability of relative HR change post-ablation to predict AF recurrence was borderline (hazard ratio 0.65 [0.41-1.01], p = .067). With patients separated into quartiles based on the relative HR change, the upper quartile with the largest relative increase in HR had a significantly lower rate of AF recurrence compared to the lowest quartile following multi variable modeling (p = .038). There were significant changes in PR (171 ± 28 to 167 ± 30 ms) and QTc (424 ± 25 to 434 ± 29 ms) intervals (both p < .001) but these were not predictive of outcome. CONCLUSION: Relative changes in HR post AF ablation correlates with AF recurrence. Further prospective studies are needed to confirm this relationship.

Spontaneous Coronary Artery Dissection (SCAD) is an important cause of myocardial infarction that typically affects women without traditional cardiovascular risk factors. It is the most common cause of myocardial infarction in pregnant and postpartum women. SCAD is often underdiagnosed due to the lack of clinician familiarity, and patients with pregnancy-associated SCAD often have more severe clinical presentations than those without. We present a case of SCAD in a multiparous woman who presented with acute chest pain in the postpartum period.
RESUMEN
BACKGROUND: Septal myectomy remains the criterion standard for treatment of symptomatic, medically refractory hypertrophic cardiomyopathy (HCM). There is no specific surgical risk calculator for septal myectomy. METHODS: This study compares the outcomes of septal myectomy at a tertiary referral center with predicted outcomes of mitral valve (MV) repair and aortic valve replacement (AVR) using the Society of Thoracic Surgeons Adult Cardiac Surgery Risk Calculator (STS Calculator). A total of 298 consecutive patients with HCM underwent isolated septal myectomy from 2011 to 2014. Observed outcomes of septal myectomy were compared with the STS Calculator predicted risk of isolated MV repair and AVR predicted within this population using 1-sample tests of proportions. RESULTS: Thirty-day mortality for myectomy in this cohort was zero. STS Calculator predicted risk of mortality for MV repair was 0.7% (Pâ¯=â¯.14) and for AVRâ¯=â¯1.1% (Pâ¯=â¯.06). Follow-up for vital status was 6.0⯱â¯0.7 years, at which 294 (98.7%) patients were alive. Hospital stay length was 4.9⯱â¯1.9 days. One (0.3%) patient experienced a postoperative deep sternal wound infection, and 1 (0.3%) patient experienced a prolonged ventilated state. Postoperative atrial fibrillation occurred in 64 (21.5%) patients. During 30 days of follow-up, no patients experienced stroke, renal failure, or needed dialysis. CONCLUSIONS: Septal myectomy, performed in a tertiary referral center, had a 30-day mortality rate of 0% and low morbidity rate. There was no difference between observed myectomy mortality and STS Calculator predicted risk for AVR and MV repair. It is possible that a larger sample could reveal lower mortality than STS prediction.

RESUMEN
BACKGROUND: Although Doppler echocardiography is routinely used to assess left ventricle cardiac output, there are limited data about the feasibility of Doppler echocardiography for right ventricular (RV) cardiac output assessment in patients with left-to-right shunt. The purpose of the study was to determine the correlation between Doppler-derived and Fick-derived RV cardiac index (CI), and the interobserver correlation in Doppler-derived RV CI assessment. METHODS: Retrospective study of patients (age ≥18 years) with unrepaired atrial septal defect who underwent cardiac catheterization and echocardiography (within 3 days), 2004-2017. RV CI was calculated using the hydraulic orifice formula: [.785 × (right ventricle outflow tract diameter)2 × right ventricular outflow tract (RVOT) time velocity integral × heart rate]/body surface area. RESULTS: A total of 128 patients (age 52 ± 17 years; female 88 [69%]) met the inclusion criteria. There was a modest correlation between Doppler-derived and Fick-derived RV CI (r = .57, P < .001), and the mean difference between Doppler-derived and Fick-derived RV CI was -.3 (95% confidence interval of agreement, -.8 to +.9) L/min/m2 . There was also a modest correlation between Doppler-derived RV CI from observer #1 and observer #2 (r = .62, P < .001), and the mean difference between Doppler-derived RV CI from observer #1 and observer #2 was -.2 (95% confidence interval of agreement, -.9 to +.6). CONCLUSIONS: The current study demonstrated a modest correlation between Doppler-derived and Fick-derived RV cardiac output, and a modest interobserver correlation in Doppler-derived RV cardiac output assessment. Further studies are required to validate these results and to explore other potential applications such as in patients with chronic pulmonary regurgitation.

OBJECTIVES: This study hypothesized that atrial fibrillation was associated with heart failure (HF) hospitalization, and that patients who received rhythm control therapy had a lower incidence of HF hospitalization and mortality. BACKGROUND: Atrial fibrillation is a known risk factor for HF hospitalization and mortality in patients with acquired heart disease. Although atrial arrhythmias are common in adults with tetralogy of Fallot (TOF), data about prevalence and outcomes of therapy for atrial fibrillation are very limited. METHODS: The MACHD (Mayo Adult Congenital Heart Disease) database was queried for adults with repaired TOF and documented atrial fibrillation from 1990 to 2017. Primary endpoint was HF hospitalization defined as admission for volume overload (pulmonary congestion and/or peripheral edema) requiring intravenous diuretics. Secondary endpoint was the effect of rhythm control therapy on HF hospitalization and all-cause mortality. Patients were divided into rhythm control and rate control groups based on the therapy initiated at the time of arrhythmia diagnosis. RESULTS: Of 415 patients, 27 (7%) had 42 HF hospitalizations. Of these 415 patients, 88 (21%) had atrial fibrillation at age 49 ± 13 years. Atrial fibrillation was an independent risk factor for HF hospitalization (adjusted hazard ratio: 2.67; 95% confidence interval: 1.04 to 7.34; p = 0.045). The 88 patients were divided into the rhythm control group (n = 61, 69%) and the rate control group (n = 27, 31%). The rate control group had higher unadjusted annual incidence of HF hospitalization (13% vs. 3%; p = 0.001) and all-cause mortality (11% vs. 4%; p = 0.002). CONCLUSIONS: Atrial fibrillation was a risk factor for HF hospitalization and mortality in TOF patients, and rhythm control therapy was protective against these adverse events.

AIMS: Previous data suggest ventricular high rate episodes (VHREs) on pacemakers are frequent and not associated with overall mortality on short term follow up. We sought to determine whether VHREs are associated with mortality, device upgrade, or change in ejection fraction on long term follow up. METHODS: A single center, retrospective study was performed on 542 patients with permanent pacemakers followed between 2011 and 2013. Follow-up was extended to 2017 for determination of long term outcomes. "True" VHREs were defined as episodes adjudicated to be due to non-sustained ventricular tachycardia on review of electrograms and "false" VHREs were defined as supraventricular arrhythmias or noise. RESULTS: VHRE occurred in 202(37.2%)/542 included patients. True VHRE was detected in 148(27.3%) while 54(10%) had false VHRE. The mean age of the population was 72⯱â¯15 years and 46% were women. Mean follow-up was 3.3⯱â¯1.4 years. The baseline characteristics of the true, false and no VHRE patients were similar. There was no difference in all-cause mortality between groups (27% mortality in true VHRE, 33% in false VHRE and 29% in no VHRE). Furthermore, there was no difference between groups with regards to any device upgrade (5% any upgrades in the VHRE, 9% in false VHRE and 5% in no VHRE.) On follow up, EF declined in all groups: -4% vs -2.4% vs -3.5% for true, false and no VHRE. CONCLUSION: VHRE are frequently encountered on remote monitoring of pacemakers and not associated with increased risk of mortality or need for downstream device upgrade.
