Abstract Aims Incidence of stroke in patients with an advanced stage hypertrophic cardiomyopathy (HCM) is associated with adverse outcome, impaired quality of life and loss of productivity. Still today, however, the real burden of stroke in both patients with and without atrial fibrillation (AF) is unresolved. To assess the prevalence and incidence of AF and stroke in patients with an advanced stage HCM implanted with cardiac implantable electronic devices (CIEDs) at our institution, a long-standing high flow referral centre for cardiomyopathies. Methods and results Clinical and instrumental data of HCM patients implanted with CIEDs [either pacemakers (PM) or implantable cardioverter defibrillator (ICD)] from 1998 to 2019 were retrospectively reviewed. Inclusion criteria were site-designated diagnosis of HCM, age at diagnosis >18 years, Follow-up >1 year. HCM phenocopies (e.g. Fabry disease) were carefully excluded. Patients were divided into three categories according to presence of AF (‘AF prior to CIED implantation’ vs. ‘AF after CIED implantation’ vs. ‘sinus rhythm’). Outcome was measured against incidence of thromboembolic events [stroke or transient ischaemic attack (TIA)] at Follow-up. Patients were also stratified by left atrial diameter (LAD) in two groups (<47 vs.  > 48mm). Of 1861 patients followed at our Unit, a total of 185 (9.9%) patients implanted with a CIED were included (57% men, mean age at implantation 54 ± 17 years). At baseline, AF was present in 72 (36%) patients. Mean CHA2DS2VASc was 1.7 + 1.3 with no differences among patients with or without AF. Patients with AF at baseline had a more pronounced LAD dilation (51 ± 7 vs. 44 ± 8, P < 0.001) and a lower ejection fraction (55 ± 11 vs. 64 ± 12, P < 0.001). After 5.0 ± 3.8 years from CIED implantation, de novo AF was detected in 24 (21%) individuals, resulting in an annual incidence rate of 4.1%/year. Overall, 89 (48%) of patients remained is sinus rhythm. Stroke/TIAs were reported in 19 (10.3%) patients: seven (37%, 1.1%/year) occurred in patients with prior history of AF, three (16%, 2.2%/year) in patients with de novo AF, and nine (63%, 2.3%/year) in patients with no history of arrhythmias documented at CIED interrogation. Among patients in sinus rhythm, those with a LAD > 48 mm had the greatest risk of stroke (4.8%/year vs. 0.5%/year, P < 0.01, for LAD > 48 vs. LAD < 47, respectively). At multivariable analysis, after adjustment for CHA2DS2VASc, AF, and obstructive physiology, only LAD was associated with a higher risk for stroke (HR: 1.09, 95% CI: 1.03–1.11, P < 0.001). Conclusions In a large cohort of consecutive high risk HCM patients referred to CIED implantation, the incidence of stroke was high, with 1-in-10 patients experiencing at least one event. Among patients in sinus rhythm, those with a marked left atrial dilatation were at highest risk of ischaemic stroke, suggesting the existence of an unmet need to stratify risk of stroke even in patients with no detected arrhythmias.

Abstract Introduction Atrial fibrillation (AF) is highly prevalent in patients with hypertrophic cardiomyopathy (HCM) and is associated with adverse outcome, impaired quality of life, loss of productivity, and the risk for embolic stroke. However, still today, the real burden of AF is unresolved due to the unknown frequency of silent asymptomatic episodes. Purpose To assess the prevalence of device-detected AF and stroke in patients with HCM implanted with cardiac implantable electronic devices (CIEDs) at our institution, a long-standing high flow referral center for cardiomyopathies. Methods Clinical and instrumental data of HCM patients implanted with CIEDs (either pacemakers [PM] or implantable cardioverter defibrillator [ICD]) from 1998 to 2019 were retrospectively reviewed. Inclusion criteria were site-designated diagnosis of HCM, age at diagnosis >18 years, >1 follow up visit, follow up >1 year. HCM phenocopies (e.g. Fabry disease) were carefully excluded. Patients were divided into three categories according to presence of AF (“AF prior to CIED implantation” vs “AF after CIED implantation” vs “no arrhythmia detected”). Outcome was measured against prevalence of thromboembolic events (stroke or transient ischemic attack [TIA]) at follow up. All-cause and cardiovascular (CV) mortality were also assessed. Results A total of 255 patients received a CIED (57% men, mean age at implantation 54±17 years). Men were younger at implantation (52±17 vs 56±18 years, p=0.022). At baseline, AF was present in 90 (35.3%) patients. During 5.0±4.1 years, de novo AF was detected in 30 (11.8%) individuals, resulting in an annual incidence rate of 6.1%/year. Overall, 135 (52.9%) of patients remained is sinus rhythm. Stroke/TIAs were reported in 30 (11.8%) patients: 16 (53.3%) occurred in patients with prior history of AF, 3 (10%) in patients with de novo AF (with men being at higher risk, OR 3.73, 95% CI 1.88–6.09, p=0.041), and 11 (36.7%) in patients with no history of arrhythmias. Long term, 45 (17.6%) patients died (CV mortality N=38, 14.9%). At multivariable analysis, history of stroke was directly related to all-cause mortality irrespective of AF in men (OR 4.15, 95% CI 1.35–12.77, p=0.018) but not in women (OR 0.891, 95% CI 0.17–4.64, p=0.801). Conclusions In a large cohort of consecutive high risk HCM patients referred to CIED implantation, the incidence of de-novo AF was high. Thromboembolic events were associated to worse outcome only in men, likely due to competing heart failure related causes in women. Strategies promoting early identification of AF and anticoagulation may play an important role in management and prevention of disease-related complications.

e19036 Background: Recent studies have shown smoking to be an independent risk factor for MDS. We aimed to assess whether smoking is associated with worse outcomes among patients (pts) with MDS at Montefiore Medical Center, Bronx, NY. Methods: Pts with MDS and chronic myelomonocytic leukemia (CMML) diagnosed between June 16, 2000 and November 13, 2020 were analyzed. Those without available tissue diagnosis or smoking history data were excluded. Descriptive statistics compared ever-smokers to non-smokers. Cox PH regression was used to analyze the risk of transformation to acute myeloid leukemia (AML) and mortality in the 2 groups and multivariable analysis (MVA) adjusted for age, sex, de novo disease and R-IPSS. Results: A total of 147 pts were identified, 109 (74.1%) had a diagnosis of de novo MDS, 89 (60.5%) had history of active or former smoking and 58 (39.5%) were non-smokers. Smokers were predominantly males (66.3%) in contrast to non-smokers (37.9%) (p=0.001). Smokers were diagnosed more frequently with high or very high risk MDS, although the difference was not statistically significant (38.1% vs 28.6%, respectively; p=0.28). TP53 mutations were numerically more frequent among smokers (24.4%), compared to non-smokers (12.8%) (p=0.16). Median follow-up time for smokers and non-smokers was 19.4 and 31.4 months, respectively. In MVA, there was a trend for increased risk of AML transformation in smokers vs non-smokers (HR 2.03, 95% CI 0.99 – 4.15; p=0.052). Smokers with MDS were found to have significantly greater mortality compared to non-smokers (HR 2.08, 95% CI, 1.22 – 3.54; p=0.007). Conclusions: Smoking was associated with worse survival among MDS pts in our cohort. Although not significantly different, the prevalence of TP53 mutations was higher among smokers. Larger studies are warranted to confirm our findings.[Table: see text]

Abstract Background Atrial fibrillation (AF) impairs mechanical function of the heart, especially atria and restoration of sinus rhythm (SR) leads to improvement of mechanics. The predicting role of changes in strain parameters for AF recurrence is not established yet. Purpose To analyse changes in left atrial (LA) and left ventricular (LV) mechanical function after conversion to SR and their prognostic values for AF recurrence during 24 months follow-up. Methods Prospective study involved 59 patients after successful electrical cardioversion (EC) because of nonvalvular AF (mean age 65±4 years, 47% female). Speckle tracking analysis (STE) was applied to calculate longitudinal strain of LV and LA before EC and within 24 hours after restoration of SR and additionally total left heart strain (TS) defined as a sum of absolute peak LV and LA strain. We calculated change in strain between AF and SR analyses expressed as delta (Δ). During follow-up we noticed AF recurrence in 42 (71%) patients, most of them (93%) during 1st year after EC. Median time of AF recurrence was 3 months. Results We noticed significant immediate post-EC improvement in peak LA longitudinal strain (PALS) and LV global longitudinal strain (LVGLS) (table). Unlike CHA2DS2-VASc score, strain parameters were predictors of AF recurrence. Every 1% increment in ΔLVGLS was related with 13% increase in AF recurrence risk (p=0.02) and every 1% increment in ΔPALS and ΔTS were related with 9% decrease in AF recurrence risk (p=0.007 and p=0.0014, respectively). Multivariate analysis revealed ΔTS as a strongest predictor with 9% decrease in AF risk per every 1% increment. The criterion of ΔTS ≤7.5% allows to predict AF recurrence with 81% sensitivity and 63% specificity. Conclusions Speckle tracking measurements are able to detect early mechanical changes in LA even within 24 hours of SR and these absolute changes in LVGLS as well as PALS can predict AF recurrence, with optimal stratification by novel parameter - TS.

OBJECTIVE The objective of this study was to identify the natural history and clinical predictors of postoperative recurrence of skull base and non–skull base meningiomas. METHODS The authors performed a retrospective hospital-based study of all patients with meningioma referred to their institution from September 1993 to January 2014. The cohort constituted both patients with a first-time presentation and those with evidence of recurrence. Kaplan-Meier curves were constructed for analysis of recurrence and differences were assessed using the log-rank test. Cox proportional hazard regression was used to identify potential predictors of recurrence. RESULTS Overall, 398 intracranial meningiomas were reviewed, including 269 (68%) non–skull base and 129 (32%) skull base meningiomas (median follow-up 30.2 months, interquartile range [IQR] 8.5–76 months). The 10-year recurrence-free survival rates for patients with gross-total resection (GTR) and subtotal resection (STR) were 90% and 43%, respectively. Skull base tumors were associated with a lower proliferation index (0.041 vs 0.062, p = 0.001), higher likelihood of WHO Grade I (85.3% vs 69.1%, p = 0.003), and younger patient age (55.2 vs 58.3 years, p = 0.01). Meningiomas in all locations demonstrated an average recurrence rate of 30% at 100 months of follow-up. Subsequently, the recurrence of skull base meningiomas plateaued whereas non–skull base lesions had an 80% recurrence rate at 230 months follow-up (p = 0.02). On univariate analysis, a prior history of recurrence (p < 0.001), initial WHO grade following resection (p < 0.001), and the inability to obtain GTR (p < 0.001) were predictors of future recurrence. On multivariate analysis a prior history of recurrence (p = 0.02) and an STR (p < 0.01) were independent predictors of a recurrence. Assessing only patients with primary presentations, STR and WHO Grades II and III were independent predictors of recurrence (p < 0.001 for both). CONCLUSIONS Patients with skull base meningiomas present at a younger age and have less aggressive lesions overall. Extent of resection is a key predictor of recurrence and long-term follow-up of meningiomas is necessary, especially for non–skull base tumors. In skull base meningiomas, recurrence risk plateaus approximately 100 months after surgery, suggesting that for this specific cohort, follow-up after 100 months can be less frequent.

Abstract Funding Acknowledgements Type of funding sources: None. INTRODUCTION STEMI gets complicated very often by a heart failure (HF), which it is important to know associated factors. The aim of this study  was to determinate the predictor factors of onset of de novo HF after STEMI in patients with no prior history of heart failure recorded at baseline. METHODS A retrospective, descriptive study from 1 center in Morocco, including 210 patients hospitalized in a cardiology intensive care unit for STEMI from September 2019 to November 2020. The main outcomes were HF Killip class at hospital presentation and intra-hospital mortality. RESULTS The main age was 59.3 ± 7.02 and Sex ratio: 2, 86. The incidence of de novo HF at admission was higher in women (40, 4% vs. 29.5%, [OR 1, 61; 95%, [CI] 0, 83-3, 11). Forty-nine point eight percent were in Killip≥ 2. The method of early revascularization was Thrombolysis in 82, 3% compared to primary coronary angioplasty without significant difference in onset of the novo HF. There was no association of age, comorbidities, delay to hospital presentation and coronary involvement with incidence of onset of de novo HF.  Women had higher mortality than men with the novo HF (28, 6% vs. 20.5%; OR: 1, 55; 95%). CONCLUSION  Gender has appeared associated to onset of de novo HF after STEMI with a superiority of the female sex after controlling for others factors described in the literature. Anterior studies have related this to the increased prevalence of microvascular disease in women predisposing them to heart failure after STEMI.

Metastatic Urothelial Carcinoma

BACKGROUND: Outcomes of patients with metastatic urothelial carcinoma (mUC) with early bone metastases (eBM) vs no early bone metastases (nBM) have not thoroughly been described in the age of immuno-oncology. OBJECTIVE: To compare survival and other clinical outcomes in patients with eBM and nBM. METHODS: We used a multi-institutional database of patients with mUC treated with systemic therapy. Demographic, metastatic site, treatment patterns, and clinical outcomes were recorded. Wilcoxon rank-sum, chi-square tests were performed. Survival was estimated by Kaplan-Meier method; multivariable Cox analysis was performed. RESULTS: We identified 270 pts, 67%men, mean age 69±11 years. At metastatic diagnosis, 27%had≥1 eBM and were more likely to have de novo vs. recurrent metastases (42%vs 19%, p <  0.001). Patients with eBM had shorter overall survival (OS) vs. those with nBM, (6.1 vs 13.7 months, p <  0.0001). On multivariable analysis, eBM independently associated with higher risk of death, HR = 2.52 (95%CI: 1.75–3.63, p <  0.0001). OS was shorter for patients with eBM who received initial immune checkpoint inhibitor vs platinum-based chemotherapy, (1.6 vs 9.1 months, p = 0.02). Patients with eBM received higher opioid analgesic doses compared to patients with nBM and received quantitatively more palliative radiation. CONCLUSIONS: Patients with mUC and eBM have poorer outcomes, may benefit less from anti-PD-1/PD-L1 therapy and represent an unmet need for novel therapeutic interventions. Dedicated clinical trials, biomarker validation to assist in patient selection, as well as consensus on reporting of non-measurable disease are required.

Background: Overweight and obese adults living with heart failure (HF) have lower mortality compared to those of normal weight. However, the specific relationships of overall weight status and central adiposity with mortality among those with HF are less well-defined. We examined the relationships among body mass index (BMI), waist circumference (WC) and mortality among patients hospitalized for HF in the REGARDS Study. Methods: REGARDS is a national cohort of US community-dwelling adults aged >45 recruited from 2003 to 2007. We measured all-cause mortality rates among 565 participants hospitalized with HF who were normal weight (BMI 18.5-24.9 kg/m 2 ), overweight (BMI 25.0-29.9 kg/m 2 ), or obese (BMI > 30.0 kg/m 2 ) at baseline. Underweight participants (BMI < 18.5 kg/m 2 ) were excluded. Baseline WC, weight, and height were measured during an in-home exam. Index HF hospitalizations during follow-up were adjudicated by a panel of experts. Vital status was determined using the Social Security Death Index or the National Death Index. Cox proportional models estimated hazard ratios for all-cause mortality following the index HF hospitalization. Models were sequentially adjusted for WC, sociodemographics, HF severity (EF and BNP during HF hospitalization, prior history of HF, prior history of diastolic dysfunction), comorbidities, and health behaviors. Results: Among 565 participants hospitalized for HF, 116 (21%) were normal weight, 209 (37%) overweight, and 240 (42%) obese at baseline. Over a mean follow-up of 2.5 years, 253 deaths occurred. In multivariable analyses, overweight was associated with lower all-cause mortality in all models (Table). Each 1-cm increase in WC was associated with higher risk of all-cause mortality, but the relationship was not statistically significant after health behaviors were added in the final model. . Conclusions: Among adults hospitalized for HF, overweight as assessed by BMI may be associated with lower risk for mortality. However, central adiposity may confer higher risk of mortality.

Antidepressant Use

Introduction: SSRIs, the most commonly prescribed antidepressants (AD) in the US, are linked to an increased intracerebral hemorrhage (ICH) risk possibly related to impaired platelet function. In the Florida Stroke Registry (FSR), we studied the proportion of cases presenting with ICH amongst AD users and the rate of SSRI prescription amongst stroke patients discharged on AD. Methods: From Jan 2010 to Dec 2019 we included 127,915 cases from FSR in whom information on AD use was available. Multivariable logistic regression was used to evaluate ICH proportions amongst AD and non-AD users and rates of prescribed SSRIs at discharge. Results: The rate of ICH amongst prior AD users (n=17,009, median age 74, IQR=19) and non-AD users (n=110,906, median age 72, IQR=21) were 11% and 14% respectively. Prior AD users were more likely to be female (17% vs. 10% male), non-Hispanic White (16% vs. 8% non-Hispanic Black vs. 12% Florida Hispanic vs. 6% Puerto Rican Hispanic), have hypertension (HTN) (14.% vs. 10%), diabetes mellitus (DM) (16% vs.12%), use oral anticoagulants (OAC) (17 % vs. 13%), antiplatelets (AP; 17% vs. 11%), and statins (17% vs. 10%) prior to hospital presentation. In multivariable analysis adjusting for age, race, prior history of HTN, DM, prior OAC, AP and statin use, AD users just as likely to present with spontaneous ICH as compared to non-AD users (OR=0.92, 95% CI 0.85, 1.01). A total of 3.4% of all ICH patients and 9% of those in whom AD information was available were discharged home on an AD (74 % SSRI, 24% other AD). Conclusion: In this large population-based study, we did not find an association between prior AD use and an increased rate of ICH. Importantly AD (mostly SSRIs) are commonly prescribed to patients with ICH in routine clinical practice. The association between types, duration, and safety of antidepressant use in ICH patients deserves further studies.

Purpose To evaluate treatment patterns in patients diagnosed with incident chronic myelogenous leukemia (CML) newly initiating therapy with imatinib, dasatinib, or nilotinib. Patients were followed to determine switching and discontinuation rates. Factors associated with switching or discontinuation from index TKI therapy, reasons for discontinuation based on electronic chart notes, and frequency of laboratory monitoring were assessed during the follow-up period. Methods A retrospective cohort study was conducted in chronic myelogenous leukemia patients aged ≥ 18 years who were identified from the Kaiser Permanente Southern California (KPSC) Cancer Registry database during the study time period of 1 January 2007 to 12 December 2013. The index date was defined as the date of the first TKI prescription (imatinib, dasatinib, or nilotinib) identified during the study time period with no prior history of TKI use within 12 months. Patients had to have continuous membership with drug benefit eligibility and no prior history of stem cell transplant (SCT) or other cancers during the 12 months prior to the index date. Baseline characteristics were identified during 12 months prior to the index date and outcomes were identified during the follow-up period after the index date. All patients were followed from index TKI therapy until end of study time period (12 December 2014), death, stem cell transplant, or disenrollment from the health plan unless one of the following occurred first: a patient switched their index therapy, or a patient discontinued their index therapy. Forward stepwise selection multivariable logistic regression models were used to evaluate factors associated with patients who continued therapy compared to those who switched or discontinued therapy with the index TKI. Chart notes were reviewed 30 days prior and 30 days post index TKI discontinuation to evaluate reasons for discontinuation. Molecular and cytogenetic testing frequency was also assessed during the follow-up period among the different patient groups. Results Two hundred sixteen patients were identified with incident chronic myelogenous leukemia and use of TKI therapy: 189 (87.5%) received imatinib, 19 (8.8%) received dasatinib, and 8 (3.7%) received nilotinib. The mean age on index date was 53 years and 63% were male; 103 patients (48%) continued on their index therapy, while 62 patients (28%) switched, and 51 patients (24%) discontinued.

Abstract Background Left Atrial (LA) phasic volumes analyses is flawed with geometrical assumption requiring high endocardial border definition. LA strain analysis is an emergent technique that overcome some of these technical limitations. Prior studies of LA mechanics in pericardiectomy patients found improvement in LA strain at follow-up and manifested as symptomatic improvement, however their relationships with survival have not been investigated. Purpose We assessed LA strain before and after pericardiectomy and its association with all- cause mortality. Methods Consecutive patients with constrictive pericarditis who underwent pericardiectomy from 2000–2017 were retrospectively analyzed, analyzing pre-operative and post-operative (at 12 months) echocardiography. Exclusion criteria included atrial fibrillation, previous left sided valve surgery, concomitant valvular surgery at the index pericardiectomy, more than mild left sided valvulopathy and poor echocardiographic windows. Strain analyses was performed with Vector velocity imaging independent software. Univariate and multivariable analyses were utilized to identify factors associated with reduced survival. Results Amongst 190 patients included in the analyses, mean age was 58.5±12.7 years and 37 (19.5%) were female. The etiology of constriction was deemed idiopathic in 61.6% of the cases, median time interval surgery-postoperative echo was 67 days (IQR 6, 312 days). During median follow up of 3.3 years (IQR 0.73, 5.9 years) there were 37 deaths. After surgery, there was a significant decrease in LA reservoir, conduit and regional wall strains. (Table 1). Multivariable analysis demonstrated that postoperative 4C AL strain reservoir was independently associated with all-cause mortality (Table 2). Conclusions In pericardiectomy patients, postoperative 4C LA strain reservoir is independently associated with all-cause mortality. Perhaps, compensatory changes of septal and antero-posterior walls during constriction explain why after surgery these walls become less dynamic, negatively impacting the overall function.
