Importance: The risk of ischemic stroke during periods of warfarin discontinuation for surgical procedures is recognized but not well characterized. Objective: The study aimed to quantitate the risk of ischemic stroke associated with high risk atrial fibrillation during periods of warfarin discontinuation. Design, Setting and Participants: A cohort of 4,060 patients (mean follow-up period of 3.5 ± 1.3 years) were randomized into the Atrial Fibrillation Follow-Up Investigation of Rhythm Management study. Patients enrolled in the study had atrial fibrillation plus at least one other risk factor for stroke or death: age ≥65 years', systemic hypertension, diabetes mellitus, congestive heart failure, transient ischemic attack, prior stroke, left atrium >50 mm, left ventricular fractional shortening <25% or left ventricular ejection fraction <40%. Exposure: Warfarin discontinuation for procedure. Main Outcome and Measures: The association of warfarin discontinuation with the incidence of ischemic stroke using pooled repeated measures and Cox proportional hazards analyses during follow-up after adjusting for age, gender, obesity, diabetes mellitus, hypercholesterolemia, cigarette smoking and study period. Results: Warfarin discontinuation for procedure occurred in 265 (0.4%) of the 71,355 person observations. Compared with those without warfarin discontinuation, the rate of ischemic stroke was higher among participants with surgery-related warfarin discontinuation (1.1% of 265 person observations vs. 0.2% of 71,090 person observations, p = 0.001). Warfarin discontinuation was associated with an increased risk for ischemic stroke (relative risk 5.8; 95% CI 1.8-18.4) after adjusting for potential confounders. The population-attributable risk associated with surgery-related warfarin discontinuation was estimated to be 23.1% (95% CI 15.2-30.9%) for ischemic stroke. Conclusions and Relevance: The 6-fold higher risk of ischemic stroke associated with discontinuation of warfarin for surgical procedures must be recognized in high risk atrial fibrillation patients and considered in the risk-benefit analysis of any procedure.

BACKGROUND: The risk of ischemic stroke during periods of warfarin discontinuation for surgical procedures is recognized nut not well characterized. We performed this study to quantitate the risk of ischemic stroke associated with strial fibrillation during periods of warfarin discontinuation. METHODS: We evaluated the association of warfarin discontinuation for procedure with the incidence of ischemic stroke using pooled repeated measures and Cox proportional hazards analyses during follow-up after adjusting for age, gender, obesity, diabetes mellitus, hypercholesterolemia, cigarette smoking, and study period in a cohort of A total of 4060 patients were randomized into the AFFIRM study. Patients enrolled in the study had AF plus at least one other risk factor for stroke or death: age >65 yrs, systemic hypertension, diabetes mellitus, congestive heart failure, transient ischemic attack, prior stroke, left atrium 50+ mm, left ventricular fractional shortening <25%, or left ventricular ejection fraction <40%. RESULTS: Warfarin discontinuation for procedure occurred in 17 (0.5%) of the 11,116 person observations with a mean follow-up period of 9.9+/-1.0 years. The rate of ischemic stroke was higher among participant with warfarin discontinuation (17 of 3313 person observations versus 209 of 36505 person observations, p=0.047). Warfarin discontinuation was associated with an increased risk for ischemic stroke (relative risk [RR], 2.2; 95% CI, 0.5 to 9.3). among the 11,802 person observations after adjusting for potential confounders. CONCLUSIONS: The risk associated with discontinuation of warfarin for procedures must be recognized and considered in the risk benefit analysis of any procedure.

Abstract Background Hypertension is one of the major risk factors of cardiovascular events in patients with atrial fibrillation (AF). However, relationship between diastolic blood pressure (DBP) and cardiovascular events in AF patients remains unclear. Methods The Fushimi AF Registry is a community-based prospective survey of AF patients in Japan. Follow-up data were available in 4,466 patients, and 4,429 patients with available data of DBP were examined. We divided the patients into three groups; G1 (DBP&lt;70 mmHg, n=1,946), G2 (70≤DBP&lt;80, n=1,321) and G3 (80≤DBP, n=1,162), and compared the clinical background and outcomes between groups. Results The proportion of female was grater in G1 group, and the patients in G1 group were older and had higher prevalence of heart failure (HF), diabetes mellitus (DM), chronic kidney disease (CKD). Prescription of beta blockers was higher in G1 group, but that of renin-angiotensin system-inhibitors and calcium channel blocker was comparable. During the median follow-up of 1,589 days, in Kaplan-Meier analysis, the incidence rates of cardiovascular events (composite of cardiac death, ischemic stroke and systemic embolism, major bleeding and HF hospitalization during follow up) were higher in G1 group and G3 group than G2 group (Figure 1). When we divided the patients based on the systolic blood pressure (SBP) at baseline (≥130 mmHg or &lt;130 mmHg), the incidence of rates of cardiovascular events were comparable among groups. Multivariate Cox proportional hazards regression analysis including female gender, age (≥75 years), higher SBP (≥130 mmHg), DM, pre-existing HF, CKD, low left ventricular ejection fraction (&lt;40%) and DBP (G1, G2, G3) revealed that DBP was an independent determinant of cardiovascular events (G1 group vs. G2 group; hazard ratio (HR): 1.40, 95% confidence intervals (CI): 1.19–1.64, G3 group vs. G2 group; HR: 1.23, 95% CI: 1.01–1.49). When we examined the impact of DBP according to 10 mmHg increment, patients with very low DBP (&lt;60 mmHg) (HR: 1.50,95% CI:1.24–1.80) and very high DBP (≥90 mmHg) (HR: 1.51,95% CI:1.15–1.98) had higher incidence of cardiovascular events than patients with DBP of 70–79 mmHg (Figure 2). However, when we examined the impact of SBP according to 20 mmHg increment, SBP at baseline was not associated with the incidence of cardiovascular events (Figure 3). Conclusion In Japanese patients with AF, DBP exhibited J curve association with higher incidence of cardiovascular events. Funding Acknowledgement Type of funding source: None

Abstract Background/Introduction Previous studies have focused on only 1 or 2 echocardiographic parameters as prognostic marker in patients with acute ischemic stroke (AIS). Purpose Various echocardiographic parameters in the same patient were systemically evaluated for their prognostic significance in AIS. Methods A total of 900 patients with AIS who underwent transthoracic echocardiography (TTE) (72.6 ± 12.0 years and 60% male) were retrospectively reviewed. Composite events including all-cause mortality, non-fatal stroke, non-fatal myocardial infarction, and coronary revascularization were assessed during clinical follow-up. Results During a median follow-up of 3.3 years (interquartile range, 0.6-5.1 years), there were 151 (16.8%) composite events. Univariable analyses showed that low left ventricular ejection fraction (LVEF) (&lt; 60%), increased peak tricuspid regurgitation (TR) velocity (&gt; 2.8 m/s) and aortic valve (AV) sclerosis were associated with composite events (P &lt; 0.05 for each). In the multivariable analyses after controlling for potential confounders, LVEF &lt; 60% (hazard ratio [HR], 1.90; 95% confidence interval [CI], 1.30-2.77; P = 0.001) and AV sclerosis (HR, 1.56; 95% CI, 1.10-2.21; P = 0.013) were independent prognostic factors associated with composite events. Multivariable analysis showed that HR for composite events gradually increased according to LVEF and AV sclerosis: HR was 2.8-fold higher in the highest-risk group than in the lowest group (P = 0.001). Conclusions In patients with AIS, LVEF &lt; 60% and the presence of AV sclerosis predicts the future vascular events. Patients with AIS exhibiting reduced LVEF and AV sclerosis may benefit from aggressive secondary prevention Abstract P1348 Figure. COX plot for composite event

Abstract Background Monitoring left-ventricular ejection fraction (LVEF) is a routinely-practiced strategy to survey patients with breast cancer (BC) towards cardiotoxic treatment effects. However, whether the LVEF as a single measurement or as a trajectory over time is truly sufficient to identify patients at high risk for cardiotoxicity is currently debated. Purpose To quantify the prognostic impact of LVEF and its change over time for predicting cardiotoxicity in women with HER2+ early BC. Methods We analyzed 1,136 echocardiography reports from 185 HER2+ early BC patients treated with trastuzumab ± chemoimmunoendocrine therapy in the neoadjuvant/adjuvant setting (Table 1). Cardiotoxicity was defined as a 10% decline in LVEF below 50%. Results Median baseline LVEF was 64% (25th-75th percentile: 60–69). Nineteen patients (10%) experienced cardiotoxicity (asymptomatic n=12, symptomatic n=7, during treatment n=19, treatment modification/termination n=14), Median time to cardiotoxicity was 6.7 months, and median LVEF decline in patients with cardiotoxicity was 18%. One-year cardiotoxicity risk was 7.6% in the 35 patients with a baseline LVEF≥60% and 24.5% in the 150 patients with a baseline LVEF<60% (Hazard Ratio (HR)=3.45, 95% CI: 1.35–8.75, Figure 1). During treatment, LVEF declined significantly faster in patients who developed cardiotoxicity than in patients without cardiotoxicity (1.3%/month vs. 0.1%/month, p<0.0001). A higher rate of LVEF decrease predicted for higher cardiotoxicity risk (HR per 0.1%/month higher LVEF decrease/month=2.50, 95% CI: 1.31–4.76, p=0.005), and cardiotoxicity risk increased by a factor of 1.7 per 5% absolute LVEF decline from baseline to first follow-up (HR=1.70, 95% CI: 1.30–2.38, p<0.0001). Thirty-six patients (19%) developed an LVEF decline of at least 5% from baseline to first follow-up (“early LVEF decline”). One-year cardiotoxicity risk was 6.8% in those without early LVEF decline and a baseline LVEF≥60% (n=117), 15.7% in those without an early LVEF decline and a baseline LVEF<60% (n=65), and 66.7% in those with an early LVEF decline and a baseline LVEF<60% (n=3), respectively (log-rank p<0.0001). Table 1. Baseline characteristics Age (years, median [IQR]) 55 [49–65] Estrogen receptor positive (n, %) 124 (67%) Neoadjuvant setting (n, %) 103 (56%) Figure 1. Risk of Cardiotoxicity. Conclusion Both a single LVEF measurement and the rate of LVEF decrease strongly predict cardiotoxicity in early BC patients undergoing HER2-targeted therapy. Routine LVEF monitoring identifies individuals at high risk of cardiotoxicity that may benefit from more sensitive screening techniques such as strain imaging.

Abstract Objective to compare the efficacy of radiofrequency ablation (RFA) and drug therapy in patients with atrial fibrillation (AFib) and heart failure (HF) within 12-month follow-up. Materials and methods 130 patients (men-75%, average age-62.8 ± 11.8 years) with AFib and HF with left ventricular ejection fraction (LVEF)&lt;50% were included in a prospective study. In 107 (82%) of the included patients, intermediate LVEF was detected (40-49%). At the time of inclusion, paroxysmal AFib (PaAFib) was recorded in 60 (46%) of patients and persistent AFib (PeAFib) in 70 (54%). AFib RFA was performed in 65 patients, 65 patients continued to receive optimal antiarrhythmic therapy. Prior to the intervention and after 12 months, all patients underwent transthoracic echocardiography and quality of life (QoL) assessment using the SF-36 questionnaire. Results the freedom from AFib within 12 months follow-up period was registred in 49 (75%) of patients in the RFA group and 26 (40%) in the drug therapy group. After 12 month follow-up period we revealed increase of LVEF (p &lt; 0.001), decrease of anteroposterior size (p &lt;0.001) and volume (p &lt; 0.001) of left atrium (LA), improvement of mental (p = 0.008) and physical (p = 0.048) health components according to the SF-36 questionnaire in the RFA group. In the group of drug rhythm control, after 12 months there was only the improvement of mental (p = 0.006) and physical p = 0.016) health components and it was much less than in RFA group (р&lt;0.001). Similar results were received in patients who were free from Afib within 12 months in both groups. Conclusions in patients with AFib and HF with LVEF &lt; 50%, restoration and maintenance of sinus rhythm using RFA was accompanied by an increase in LVEF, decrease of  LA size, and an improvement of QoL. In the group of drug therapy, there was a lower freedom from AFib and there was the slight improvement only in QoL.

Abstract Background Percutaneous coronary intervention (PCI) presents a relevant alternative to coronary bypass surgery for the treatment of patients with complex coronary artery disease and high perioperative risk. By temporary implantation of a percutaneous ventricular assist devices (pVAD) interventionalists attempt to anticipate the hemodynamic risk of those high-risk patients in a so-called protected PCI. The Impella® system presents the currently most common device for protected PCI and could show hemodynamic stability in earlier trials. Methods This study is a retrospective, observational multi-center registry of ten hospitals in Germany. We included patients undergoing protected high-risk PCI with Impella® support. The primary endpoint was defined as major adverse cardiac events (MACE) during a 180-day follow-up and consisted of all-cause mortality, myocardial infarction (MI) and stroke. Results Six of the participating hospitals performed a follow-up. In total, 157 patients (80.3% male; mean age 71.8±10.8 years) were included in the present study. Prior to PCI, median left ventricular ejection fraction was 39.0% (25.0%-50.0%) and median SYNTAX-Score I was 33.0 (24.0–40.5). The 180-day follow-up was available for 149 patients (94.9%). Eight patients (5.1%) were lost to follow-up. During the follow-up period, 34 patients (22.8%) suffered from a MACE. A total of 27 patients (18.1%) died. Nine patients (6.0%) sustained a MI, while 4 patients (2.7%) had a stroke. Kaplan-Meier curves for primary endpoint Conclusions Patients undergoing protected high-risk PCI with Impella® support show a good 180-day clinical outcome regarding rates of MACE and mortality. However, a head-to-head comparison of Impella supported patients to protected PCI with other pVADs is pending.

Abstract We conducted a 4-yr prospective trial to evaluate the long-term effects of combined deferiprone (DFP)/deferoxamine (DFO) on reversal of cardiac complications in thalassemia major compared to those of DFO alone. Twenty-eight patients (pts) with cardiac disease requiring medication were stratified according to their risk for cardiac death. Fourteen pts were high risk, serum ferritin (SF) > 2500 ug/L on two-thirds of occasions since the onset of cardiac disease. Of those with a SF < 2500 ug/L (low risk), six had progressive decrements of left ventricular ejection fraction (LVEF). Nine high-risk pts and six low-risk pts were placed on DFP/DFO (DFP, 75 mg/kg/d divided t.i.d.; DFO, 40 – 50 mg/kg over 8 – 12 h at night 5 – 7 d/wk. The others infused DFO alone. If SF fell below 500 ug/L, DFO infusions were reduced to 2 d/wk. Cardiac follow-up (including blood work and ECG) was done at 4-m intervals. M-mode and two-dimensional echocardiograms were done at 4- to 6-m intervals. Cardiac T2* was not available at the beginning of the study. All but eight patients (3 death, 1 refusal, 2 claustrophobic, 2 pacemaker) subsequently had at least one T2* assessment. Routine lab tests were done at 1- to 6-m intervals. Blood counts were done at 7- to 10-d intervals for those taking DFP. Mean follow-up was approximately 40 m. Compliance with DFO was significantly better among low-risk pts in both treatment groups (DFP/DFO, 82% vs 61%; DFO alone, 83% vs 52%) as was that with DFP (94% vs 76%). At baseline, no statistically significant differences were observed between the SF levels, LVEFs or left ventricular shortening fractions (LVSFs) of pts on DFP/DFO or DFO alone in either risk group except for the LVEFs of the low-risk group (DFP/DFO, 56.5% +/− 5.5%; DFO alone, 65.4% +/− 5.0%; p = 0.032). In the high-risk group, four cardiac events (3 deaths, 1 worsening of CHF) occurred in the group getting DFO alone vs none in the DFP/DFO-treated group. The latter pts showed a decrease in SF and an increase in both LVEF and LVSF at the end of study (EOS). The three pts who died (at 17 to 35 m) had increased SFs. These pts were not rescued by IV DFO (98 +/− 12 mg/kg/d). The two DFO-treated pts who survived had marginally improved T2*s (1.5 to 3.0 ms and 7.6 to 8.8 ms) over the year prior to EOS. Only one of the seven evaluable pts on DFP/DFO had a T2* < 10 ms, the others averaging 19.4 +/− 6.7 ms. Among the low-risk pts, those on DFP/DFO showed a reduction in SF and an improvement in both LVEF and LVSF. Those on DFO alone had increased SF but essentially no change in LVEFs or LVSFs. Five pts on DFP/DFO had T2* evaluations. In two pts, T2* rose from 9.0 to 37 ms (38 m) and from 9.3 to 11.8 ms (17 m). The remaining three had T2* values > 20 ms at EOS. Similar results were seen in low-risk pts on DFO alone. These finding clearly support the notion that DFP/DFO has a beneficial effect upon the heart, even in well established disease. Moreover, our finding of low T2* values associated with low SF levels indicates the importance of tailoring treatment to each individual.

Background - Bucindolol is a genetically targeted β-blocker/mild vasodilator with the unique pharmacologic properties of sympatholysis and ADRB1 Arg389 receptor inverse agonism. In the GENETIC-AF trial conducted in a genetically defined heart failure (HF) population at high risk for recurrent atrial fibrillation (AF), similar results were observed for bucindolol and metoprolol succinate for the primary endpoint of time to first atrial fibrillation (AF) event; however, AF burden and other rhythm control measures were not analyzed. Methods - The prevalence of ECGs in normal sinus rhythm, AF interventions for rhythm control (cardioversion, ablation and antiarrhythmic drugs), and biomarkers were evaluated in the overall population entering efficacy follow-up (N=257). AF burden was evaluated for 24 weeks in the device substudy (N=67). Results - In 257 patients with HF the mean age was 65.6 ± 10.0 years, 18% were female, mean left ventricular ejection fraction (LVEF) was 36%, and 51% had persistent AF. Cumulative 24-week AF burden was 24.4% (95% CI: 18.5, 30.2) for bucindolol and 36.7% (95% CI: 30.0, 43.5) for metoprolol (33% reduction, p < 0.001). Daily AF burden at the end of follow-up was 15.1% (95% CI: 3.2, 27.0) for bucindolol and 34.7% (95% CI: 17.9, 51.2) for metoprolol (55% reduction, p < 0.001). For the metoprolol and bucindolol respective groups the prevalence of ECGs in normal sinus rhythm was 4.20 and 3.03 events per patient (39% increase in the bucindolol group, p < 0.001), while the rate of AF interventions was 0.56 and 0.82 events per patient (32% reduction for bucindolol, p = 0.011). Reductions in plasma norepinephrine (p = 0.038) and NT-proBNP (p = 0.009) were also observed with bucindolol compared to metoprolol. Conclusions - Compared with metoprolol, bucindolol reduced AF burden, improved maintenance of sinus rhythm, and lowered the need for additional rhythm control interventions in patients with HF and the ADRB1 Arg389Arg genotype.

Introduction: Based on the data from CASTLE-AF trial, in patient with Atrial Fibrillation (AF) and heart failure (HF) catheter ablation may offer a significant reduction in both death, and hospitalization, while promoting maintenance of sinus rhythm as well as improvement in left ventricular ejection fraction (LVEF). This multi-center randomized trial is hailed as a paradigm shifting study in catheter ablation, however it is not without fault. One of the critiques of the CASTLE-AF trial was the high frequency of crossover between the treatment arms. To help sort out this potential source of confounding, we performed a systematic meta-analysis of prospective trials for catheter ablation in AF in patients with Class II through IV heart failure. Hypothesis: The reduction in death, and hospitalization, as well as the maintenance in sinus rhythm and improvement in LVEF seen CASTLE-AF trial are support by other similarly designed AF ablation trials. Methods: Using the inclusion/exclusion criteria from the CASTLE-AF trial, we performed a systematic meta-analysis of 28 published studies. Randomized and non-randomized observational studies comparing the impact of catheter ablation of AF in HF. Studies were identified using the Cochrane Library, EMBASE, and PubMed. Results: A total of 29 studies were identified (n =2,339). Mean follow-up was 25 (95% confidence interval, 18-40) months. Efficacy in maintaining sinus rhythm at follow-up end was 60% (43%-76%). Left ventricular ejection fraction improved significantly during follow-up by 15% (P<0.001). Conclusions: Following our meta-analysis, we found data to support the findings of improved LVEF and maintenance of sinus rhythm reported in the CASTLE-AF trial. However, due to differences in study design, we were unable to further validate the reduction in both hospitalization and death seen in CASTLE-AF. We recommend future prospective trials be conducted without cross over to further explore this topic.

ABSTRACT Atrial Fibrillation (AF) is an arrhythmia characterized by disorganization of atrial depolarization resulting in the impaired mechanical function of the atrium. Management of AF aims to prevent complications of ischemic stroke and systemic embolism, carried out by the administration of anticoagulant, warfarin, but warfarin has many side effects. New Oral Anticoagulants (NOAC) can be used as alternatives in preventing complications of AF.New anticoagulants such as dabigatran, rivaroxaban, and apixaban have better effects than other anticoagulants such as warfarin and have major side effects of bleeding and minimal relevant bleeding. Based on a national survey in Denmark to see a balance between stroke and intracranial bleeding, CHA2DS2-VASc 1 scores were only apixaban and both dabigatran doses (110 mg bid and 150 mg bid) which provided better clinical benefits than warfarin, but if the CHA2DS2- score VASc ≥2 of all NOACs is superior to warfarin. Atrial fibrillation can cause ischemic stroke and systemic embolism. New Oral Anticoagulant (NOACs) can be used as a solution to prevent complications from AF with minimal side effects. It is expected that the presence of new anticoagulants can reduce the rate of ischemic stroke and ischemic embolism due to AF with minimal side effects of bleeding and other side effects. Keywords: Anticoagulant,  Atrial Fibrillation, NOAC, Warfarin   ABSTRAK Atrial Fibrilasi (AF) adalah suatu aritmia yang ditandai dengan disorganisasi dari depolarisasi atrium sehingga berakibat pada gangguan fungsi mekanik atrium. Penatalaksanaan AF bertujuan mencegah komplikasiyakni stroke iskemik dan emboli sistemik, dilakukan dengan cara pemberian anti-koagulan yakni warfarin. Pemberian warfarin  memiliki banyak efek samping.  Novel Oral Anti Coagulants (NOAC) dapat dijadikan alternatif  dalam mencegah komplikasi AF. Anti-koagulan baru seperti dabigatran, rivaroxaban dan apixaban memiliki efektifitas yang lebih baik daripada anti-koagulan lainnya seperti warfarin dan memiliki efek samping perdarahan mayor dan perdarahan relevan yang minimal. Berdasarkan survei nasional di Denmark untuk melihat keseimbangan antara stroke dan perdarahan intra-kranial didapatkan bila skor Congestive heart failure, Hypertension, Age ≥75 years (skor 2), Diabetes mellitus, Stroke history (skor 2), peripheral Vascular disease, Age between 65 to 74 years, Sex Category (female) dan “C” adalah adanya disfungsi ventrikel kiri sedang hingga berat (Left Ventricular Ejection Fraction/LVEF ≤ 40%)  CHA2DS2-VASc  1 hanya apixaban dan kedua dosis dabigatran (110 mg b.i.ddan 150 mg b.i.d) yang memberikan manfaat klinis yang lebih baik daripada warfarin, tetapi apabila skor CHA2DS2-VASc ≥2 seluruh NOAC lebih superior dibanding warfarin.AF dapat menyebabkan stroke iskemik dan emboli sistemik.NOAC dapat dijadikan solusi untuk mencegah komplikasi dari AF dengan efek samping yang minimal. Diharapkan dengan hadirnya anti-koagulan baru dapat menurunkan angka stroke iskemik dan emboli iskemik akibat AF dengan efek samping perdarahan dan efek samping lainnya yang minimal.
