Assessment of patient-reported treatment burden in patients with coronary artery disease.

Introduction: Patient-reported treatment burden (TBN) refers to the patient's time and effort invested in the management of their chronic health conditions. The aim of this research was to explore TBN in patients with coronary artery disease (CAD). Methods: Consecutive patients with chronic medical condition(s) were invited to complete the study questionnaires (TBN and EQ-5D). Results: Of 514 enrolled patients, 116 (22.6%) patients had CAD. The mean TBN score for CAD vs. non-CAD was 40.49 ±21.54 and 46.17 ±21.44 (p = 0.023), respectively. Conclusions: Patients with CAD could have a lower TBN in comparison to patients with other chronic medical conditions.

Clinical outcomes of patients with atrial fibrillation in relation to multimorbidity status changes over time and the impact of ABC pathway compliance: a nationwide cohort study.

Patients with atrial fibrillation (AF) commonly have associated comorbidities. The primary aim was to determine the effect of increasing numbers of comorbidity on clinical outcomes. The secondary aims were (1) the association of comorbidities with oral anticoagulants (OAC) discontinuation, and quality control, (2) the impact of holistic care based on the ABC pathway on clinical outcomes. The primary outcome was the composite of all-cause death, ischemic stroke/systemic embolism, major bleeding, and heart failure. A total of 3405 patients were enrolled; mean age 67.8 ± 11.3 years, 41.8% female. Compared to low comorbidity group [n = 897 (26.3%)], hazard ratios (HR) and 95% confidence intervals (CI) for the composite outcome in the high [n = 929 (27.3%)] and moderate comorbidity [n = 1579 (46.4%)] groups were 5.40 (4.20-6.94) and 2.54 (1.97-3.27), respectively. ABC pathway adherence was associated with reduction of the composite outcome overall (HR 0.63; 0.54-0.74). High comorbidity adversely impacted on OAC use, OAC discontinuation, and quality of warfarin control. If quality of anticoagulation control was included as part of the ABC pathway adherence, the reduction in composite outcome risk was greater (HR 0.46; 0.36-0.58). During 3-year follow-up, 33.9% changed from low- to the moderate-high comorbidity groups and 22.3% changed from moderate- to the high comorbidity group. In conclusion, comorbidity burden in AF patients is an important determinant of clinical outcomes, and changed over time. OAC use, OAC discontinuation, and quality of OAC control were impacted by comorbidity burden. ABC pathway adherence was associated with a reduced risk of adverse clinical outcomes.

Association of Insulin Resistance With Cardiovascular Disease and All-Cause Mortality in Type 1 Diabetes: Systematic Review and Meta-analysis.

OBJECTIVE: The association of insulin resistance (IR) with cardiovascular disease (CVD) and all-cause mortality in type 1 diabetes (T1D) remains unclear. PURPOSE: To investigate whether IR is associated with CVD and all-cause mortality among individuals with T1D. DATA SOURCES: PubMed, Embase, and the Cochrane Library databases were searched from inception to 31 October 2023. STUDY SELECTION: Observational studies reporting the associations between IR, as calculated by the estimated glucose disposal rate (eGDR), and the risk of CVD and all-cause mortality in individuals with T1D were eligible for inclusion. DATA EXTRACTION: Data from eight selected studies were extracted, pooled by random-effects models, and results are presented as hazard ratios (95% CIs). DATA SYNTHESIS: Eight studies involving 21,930 individuals were included, of which five studies involving 19,960 individuals with T1D reported the risk of CVD. During a median follow-up of 10 years, there were 2,149 cases of incident CVD. The pooled hazard ratio for composite CVD outcome per 1-unit increase in the eGDR index was 0.83 (95% CI 0.78-0.90, I2 = 58.9%). Five studies involving 19,403 individuals reported the risk of all-cause mortality. During a median follow-up of 10 years, 1,279 deaths were observed. The pooled hazard ratio for all-cause mortality per 1-unit increase in the eGDR index was 0.84 (95% CI 0.81-0.87, I2 = 0%). LIMITATIONS: The small number of available studies restricted our ability to perform meta-regression analyses or more detailed subgroup analyses. CONCLUSIONS: IR, as calculated by the eGDR, may be an additional risk factor for CVD and all-cause mortality in T1D.

Sex-specific comparative outcomes between oral anticoagulants in patients with atrial fibrillation: a systematic review and meta-analysis.

AIMS: Women with atrial fibrillation (AF) are under-represented in randomised controlled trials (RCTs) of direct oral anticoagulants (DOACs). This systematic review and meta-analysis of RCTs and observational studies examined sex-specific outcomes of DOACs in AF. METHODS: PubMed, Embase, Web of Science and Cochrane Library were searched from January 2008 to November 2022. Sex-specific comparative outcomes of stroke/systemic embolism (SE), major bleeding, intracranial haemorrhage (ICH) and gastrointestinal bleeding (GIB) between oral anticoagulants were pooled using random effects models. P values for interaction were calculated to examine differences in results between sexes. RCTs and observational studies were meta-analysed separately. RESULTS: 5 RCTs and 33 observational studies were included, totalling 1 085 931 women and 1 387 123 men. Meta-analyses showed that for both sexes, DOAC versus warfarin was generally associated with lower risk of stroke/SE, major bleeding and ICH; in DOAC-DOAC comparisons, rivaroxaban versus dabigatran had higher GIB risk. The only sex-specific difference observed was that when compared with warfarin, women had higher GIB risk with rivaroxaban (women: pooled risk ratio (pRR)=1.34, 95% CI=1.18 to 1.51; men: pRR=0.97, 95% CI=0.85 to 1.10; p value for interaction (p for interaction)<0.001) and possibly dabigatran (women: pRR=1.25, 95% CI=0.92 to 1.70; men: pRR=0.83, 95% CI=0.72 to 0.97; p-for-interaction=0.02). The sex difference in GIB remained for rivaroxaban when a Bonferroni-corrected significance level was used (α=0.003). No sex-specific GIB data for apixaban and edoxaban was available for the meta-analysis. CONCLUSIONS: For both sexes, DOACs generally demonstrated favourable effectiveness and safety over warfarin. However, observational data suggested that women may have higher GIB risk with rivaroxaban and possibly dabigatran than warfarin. Further studies are warranted to verify our findings and elucidate sex-specific GIB risk with apixaban and edoxaban, of which the data is currently lacking.

Noise and Light Exposure and Cardiovascular Outcomes: A Review of Evidence, Potential Mechanisms and Implications.

Cardiovascular diseases (CVD) are the leading cause of global non-communicable disease-related deaths. In recent years there has been increasing discussion about the influence of environmental risk factors, including noise and light, on the occurrence and course of these conditions. Recent studies highlight the impact of road traffic noise on an elevated risk of stroke and increased mortality in the course of coronary artery disease (CAD). In the case of threats arising from light pollution, there are more limited published studies; however, these show an increased hospitalization risk associated with CAD. Existing analyses cannot dismiss these environmental factors, highlighting the need for further research. Future studies should investigate not only road traffic noise but also consider railway and aircraft noise. Additionally, research on light pollution should include younger individuals too. In the future, incorporating individual assessments of noise and light pollution exposure, along with the identification of particularly vulnerable groups, could contribute to refining methods of individual risk stratification and implementing new preventive strategies.

Performance of HAS-BLED and DOAC scores to predict major bleeding events in atrial fibrillation patients treated with direct oral anticoagulants: A report from a prospective European observational registry.

BACKGROUND: The DOAC score has been recently proposed for bleeding risk stratification of patients with atrial fibrillation treated with direct oral anticoagulants (DOAC). OBJECTIVE: To compare the performance of HAS-BLED and DOAC score in predicting major bleeding events in a contemporary cohort of European AF patients treated with DOAC. METHODS: We included patients derived from a prospective observational registry of European AF patients. HAS-BLED and DOAC scores were calculated as per the original schemes. Our primary endpoint was major bleeding events. Receiver operating characteristic (ROC) curves were used to compare the predictive ability of the scores. RESULTS: A total of 2834 AF patients (median age [IQR] 69 [62-77] years; 39.6 % female) treated with DOAC were included in the analysis. According to the HAS-BLED score, 577 patients (20.4 %) were categorized as very low risk of bleeding, as compared to 1276 (45.0 %) according to DOAC score. A total of 55 major bleeding events occurred with an overall incidence of 1.04 per 100 patient-years. Both scores showed only a modest ability for the prediction of bleeding events (HAS-BLED area under the curve [AUC], 0.65, 95 % confidence interval [CI] 0.55-0.70; DOAC score AUC 0.62, 95 % CI 0.59-0.71, p for difference = 0.332]. At calibration analysis, the DOAC score showed modest calibration, especially for patients at high risk, when compared to HAS-BLED. CONCLUSION: In a contemporary cohort of DOAC-treated AF patients, both HAS-BLED and DOAC scores only modestly predicted the occurrence of major bleeding events. Our results do not support the preferential use of DOAC score over HAS-BLED.

Outpatient treatment of decompensated heart failure: A systematic review and study level meta-analysis.

Patients with acutely decompensated heart failure (ADHF) are usually admitted to hospital for management. There is growing interest in delivering intravenous (IV) diuretic therapy at home, in the community or at hospital day-care units; the safety and effectiveness of outpatient-based management (OPM) for ADHF has not been established. We conducted a systematic literature review and meta-analysis to investigate the short-term safety and effectiveness of OPM compared with inpatient management (IPM) of ADHF. Pre-specified endpoints were 30 day mortality and 30 day hospitalization. The meta-analysis was conducted using RevMan 5.4 software. Twenty-nine studies of OPM were identified, including 7683 patients. Only five studies directly compared OPM (n = 1303) with IPM (n = 2047), including three observational studies, and two randomized controlled trials (RCTs). The other 24 studies only stated OPM outcomes. For the five studies comparing IPM versus OPM, patients were generally aged >75 years and of similar age for each strategy, with a similar proportion of men (56%). In a study-level, aggregate analysis, 30 day all-cause mortality was 9.3% (121/1303) for OPM, compared with 15.6% (320/2047) for IPM [OR 0.29 (95% CI 0.09, 0.93) P = 0.04]. Four studies reported 30 day all-cause hospitalization; 22.0% for IPM versus 16.8% for OPM [OR 0.73 (95% CI 0.61, 0.89), P = 0.001]. In the two RCTs, we found no difference in 30 day mortality or hospitalization. In observational studies, OPM of ADHF is associated with lower 30 day hospitalization and lower 30 day mortality; such differences were not observed in two small, single-centre RCTs. A substantial, multicentre RCT is required to confirm the safety and effectiveness of OPM for ADHF.

Validation of the NULL-EASE Score for Predicting Survival in a Multiethnic Asian Cohort of Out-of-Hospital Cardiac Arrest.

BACKGROUND: NULL-PLEASE is a simple and accurate clinical scoring system developed in a Western cohort of patients with out-of-hospital cardiac arrest (OHCA). The need for blood test results limits its use in early stages of care. We adapted and validated the NULL-EASE score (without laboratory tests) in an independent, multiethnic Asian cohort of patients with out-of-hospital cardiac arrest. METHODS AND RESULTS: Using the Singapore OHCA registry, we included consecutive adult patients with out-of-hospital cardiac arrest who survived to hospital admission between April 2010 to December 2020. In-hospital mortality was the primary outcome. Logistic regression analyses were performed with STATA MP v18. Of 3274 patients (median age 64, interquartile range 54-75; 67.9% male) included in the study, 2476 (75.6%) had in-hospital mortality. NULL-EASE score was significantly lower in survivors compared with nonsurvivors (median [inter quartile range] 3 [1-4] versus 6 [4-7]; P<0.001) and strongly predictive of mortality (area under receiver operating characteristic, 0.81 [95% CI, 0.79-0.83]). Patients with a score of ≥3 had higher odds of mortality (adjusted odds ratio, 8.11 [95% CI, 6.57-10.00]) when compared with those with lower scores, after adjusting for sex, residential arrest, diabetes, respiratory disease, and stroke. A cutoff value of ≥3 predicted mortality with 92.2% sensitivity, 84.1% positive predictive value, 46.1% specificity, and 65.5% negative predictive value. NULL-EASE score performed better in younger compared with older patients (area under receiver operating characteristic, 0.82 versus 0.77, P=0.008). CONCLUSIONS: The NULL-EASE score has good discriminative performance (sensitivity and accuracy) in our multiethnic Asian cohort, but the cutoff of ≥3 falls short of the desired level of specificity for therapeutic decision-making.

Real-world evidence of early rhythm control in patients with atrial fibrillation: A systematic review and meta-analysis.

BACKGROUND: The favorable benefits of early rhythm control (ERC) therapy in newly diagnosed patients with atrial fibrillation (AF) have been demonstrated in the EAST-AFNET 4 trial. However, the generalizability and applicability of ERC in real-world clinical settings remain inconclusive. METHODS: We conducted a systematic search of the PubMed and Embase databases to identify observational studies published between January 2020 and February 2024 that focused on real-world evidence pertaining to ERC. The effectiveness and safety outcomes in our study were analogous to those evaluated in the EAST-AFNET 4 trial. RESULTS: A total of 4 observational studies that fulfilled the inclusion criteria of EAST-AFNET 4 were included, involving 130,970 patients with AF, 30.7% of whom received ERC therapy. In our pooled analysis using the fixed-effects model, compared with rate control, ERC significantly decreased the occurrence risk of the primary composite outcome (hazard ratio [HR] 0.86, 95% confidence interval[CI] 0.82-0.91), cardiovascular death (HR 0.87, 95% CI 0.78-0.98), stroke (HR 0.80, 95% CI 0.73-0.87), and hospitalization with worsening heart failure (HR 0.91, 95% CI 0.84-0.99) or acute coronary syndrome (HR 0.72, 95% CI 0.59-0.87). In terms of safety outcomes, there were no differences in the composite safety outcome (HR 1.00, 95% CI 0.95-1.05) and all-cause death (HR 0.93, 95% CI 0.82-1.06) between the two studied groups. CONCLUSIONS: ERC therapy showed favorable effectiveness outcomes compared with rate control, whereas the safety outcomes between the two therapeutic strategies did not differ significantly, supporting the benefits of ERC therapy over rate control in selected real-world patients with AF. REGISTRATION: The study protocol was registered to PROSPERO (CRD42023443569).

Remote rhythm monitoring using a photoplethysmography smartphone application after cardioversion for atrial fibrillation.

Aims: Direct current cardioversion (DCCV) is a commonly utilized rhythm control technique for atrial fibrillation. Follow-up typically comprises a hospital visit for 12-lead electrocardiogram (ECG) two weeks post-DCCV. We report the feasibility, costs, and environmental benefit of remote photoplethysmography (PPG) monitoring as an alternative. Methods and results: We retrospectively analysed DCCV cases at our centre from May 2020 to October 2022. Patients were stratified into those with remote PPG follow-up and those with traditional 12-lead ECG follow-up. Monitoring type was decided by the specialist nurse performing the DCCV at the time of the procedure after discussing with the patient and offering them both options if appropriate. Outcomes included the proportion of patients who underwent PPG monitoring, patient compliance and experience, and cost, travel, and environmental impact. Four hundred sixteen patients underwent 461 acutely successful DCCV procedures. Two hundred forty-six underwent PPG follow-up whilst 214 underwent ECG follow-up. Patient compliance was high (PPG 89.4% vs. ECG 89.8%; P > 0.999) and the majority of PPG users (90%) found the app easy to use. Sinus rhythm was maintained in 71.1% (PPG) and 64.7% (ECG) of patients (P = 0.161). Twenty-nine (11.8%) PPG patients subsequently required an ECG either due to non-compliance, technical failure, or inconclusive PPG readings. Despite this, mean healthcare costs (£47.91 vs. £135 per patient; P < 0.001) and median cost to the patient (£0 vs. £5.97; P < 0.001) were lower with PPG. Median travel time per patient (0 vs. 44 min; P < 0.001) and CO2 emissions (0 vs. 3.59 kg; P < 0.001) were also lower with PPG. No safety issues were identified. Conclusion: Remote PPG monitoring is a viable method of assessing for arrhythmia recurrence post-DCCV. This approach may save patients significant travel time, reduce environmental CO2 emission, and be cost saving in a publicly-funded healthcare system.

Is it high time to leave the chronic disease care of rural older people to village doctors in China: Insights from a population-based atrial fibrillation screening study.

OBJECTIVE: No study has systematically investigated the quality of long-term care delivered to the rural older people with chronic diseases, such as atrial fibrillation (AF) in China. This study aims to provide contemporary data on the prevalence and awareness of AF among the older population in rural China and to evaluate healthcare knowledge and delivery by village doctors. DESIGN: A cross-sectional study. SETTING: Rural villages in Daqiao and Xiaoji towns of Jiangsu Province, China. PARTICIPANTS: Rural population aged ≥65 years. OUTCOME MEASURES: AF was identified using 12-lead electrocardiography in the first-step (government-led health examination) and single-lead electrocardiography in the second-step (in-house AF screening). Questionnaire surveys were designed for the AF patients and their village doctors. RESULTS: Among 31,342 permanent residents, 12,630 (40.3 %) declined, 7,956 (25.3 %) participated in the first-step and 10,756 (34.3 %) in the second-step. The overall AF detection rate was 4.3 % (810/18,712). Of the 810 AF patients (mean age 76.1±5.9 years; 51.4 % female), 51.5 % were illiterate, only 2.6 % could use smartphone applications, and 8.1 % lived with their children. Common risk factors were older age, men, hypertension, diabetes, prior stroke, vascular disease, and congestive heart failure. Among the 402 patients with known AF, 367 were at high risk of stroke and 10.9 % (40/367) were anticoagulated. Only 17.6 % patients with known hypertension had blood pressure level <140/90 mmHg, and 6.0 % with known diabetes had a fasting blood glucose level ≤6.1 mmol/L. Only 7.3 % (9/122) village doctors reported having the knowledge of integrated care AF management. CONCLUSIONS: This study identified AF in 4.3 %, but AF management was suboptimal in rural China. The current village doctor-dominant rural healthcare system is far from delivering standardized AF management for older patients in rural China. There is an urgent need to empower the village doctors in optimising the care of AF patients.

Routine cardiac biomarkers for the prediction of incident major adverse cardiac events in patients with glomerulonephritis: a real-world analysis using a global federated database.

RATIONALE & OBJECTIVE: Glomerulonephritis (GN) is a leading cause of chronic kidney disease (CKD). Major adverse cardiovascular events (MACE) are prolific in CKD. The risk of MACE in GN cohorts is multifactorial. We investigated the prognostic significance of routine cardiac biomarkers, Troponin I and N-terminal pro-BNP (NT-proBNP) in predicting MACE within 5 years of GN diagnosis. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Data were obtained from TriNetX, a global federated health research network of electronic health records (EHR). EXPOSURE OR PREDICTOR: Biomarker thresholds: Troponin I: 18 ng/L, NT-proBNP: 400 pg/mL. OUTCOMES: Primary outcome: Incidence of major adverse cardiovascular events (MACE). SECONDARY OUTCOME: was the risk for each individual component of the composite outcome. ANALYTICAL APPROACH: 1:1 propensity score matching using logistic regression. Cox proportional hazard models were used to assess the association of cardiac biomarkers with the primary and secondary outcomes, reported as Hazard Ratio (HR) and 95% confidence intervals (CI). Survival analysis was performed which estimates the probability of an outcome over a 5-year follow-up from the index event. RESULTS: Following PSM, 34,974 and 18,218 patients were analysed in the Troponin I and NTproBNP cohorts, respectively. In the Troponin I all cause GN cohort, 3,222 (9%) developed composite MACE outcome HR 1.79; (95% CI, 1.70, 1.88, p < 0.0001). In the NTproBNP GN cohort, 1,686 (9%) developed composite MACE outcome HR 1.99; (95% CI, 1.86, 2.14, p < 0.0001). LIMITATIONS: The data are derived from EHR for administrative purposes; therefore, there is the potential for data errors or missing data. CONCLUSIONS: In GN, routinely available cardiac biomarkers can predict incident MACE. The results suggest the clinical need for cardiovascular and mortality risk profiling in glomerular disease using a combination of clinical and laboratory variables.

SGLT2 Inhibitors, but Not GLP-1 Receptor Agonists, Reduce Incidence of Gout in People Living With Type 2 Diabetes Across the Therapeutic Spectrum.

PURPOSE: This study aimed to evaluate the relative association between sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1Ra) with the incidence of gout in patients with type 2 diabetes (T2D) using real-world data. METHODS: We conducted a cohort study using data from TriNetX (an international federated database). We included patients commenced on metformin or insulin, either alone or with an SGLT2i or GLP-1Ra, at least 2 years prior to date of analysis. We propensity score matched (PSM) (1:1) for 26 relevant characteristics. Time to event analysis was performed to assess the incidence of gout, all-cause mortality (positive control), and herpes zoster infection (negative control) at 5 years following drug initiation. FINDINGS: Prior to PSM, the cohort numbers were as follows: metformin control, 1,111,449; SGLT2i with metformin, 101,706; GLP-1Ra with metformin, 110,180, insulin control, 1,398,066; SGLT2i with insulin, 68,697; and GLP-1Ra with insulin, 99,693. SGLT2i with metformin demonstrated a statistically significant decreased incidence of gout at 5 years compared to the metformin control cohort (HR 0.75 [95% CI 0.69-0.82], P < 0.0001). Similarly, SGLT2i with insulin demonstrated a statistically significant decreased incidence of gout at 5 years compared to the insulin control cohort (HR 0.83 [95% CI 0.74-0.92], P < 0.0001). Conversely, no significant disparity in gout incidence was observed between the use of GLP-1Ra and matched controls. Subgroup analysis showed an associated reduced incidence of gout with SGLT2i use compared to GLP-1Ra, in groups using metformin (HR 0.77 [95% CI 0.70-0.86], P < 0.0001) or insulin (HR 0.82 [95% CI 0.73-0.91)], P < 0.0001). IMPLICATIONS: In this large-scale real-world study, SGLT2i use was associated with a lower incidence of gout in patients with T2D compared to both insulin and metformin controls. These findings suggest the potential of SGLT2i as a promising therapeutic option for treating gout in this population.

Usefulness of the C2HEST score to predict new onset atrial fibrillation. A systematic review and meta-analysis on >11 million subjects.

BACKGROUND: The incidence of new-onset atrial fibrillation (NOAF) is increasing in the last decades. NOAF is associated with worse long-term prognosis. The C2HEST score has been recently proposed to stratify the risk of NOAF. Pooled data on the performance of the C2HEST score are lacking. METHODS: Systematic review and meta-analysis of observational studies reporting data on NOAF according to the C2HEST score. We searched PubMed, Web of Science and Google scholar databases without time restrictions until June 2023 according to PRISMA guidelines. Meta-analysis of the area under the curve (AUC) with 95% confidence interval (95% CI) and a sensitivity analysis according to setting of care and countries were performed. RESULTS: Of 360 studies, 17 were included in the analysis accounting for 11,067,496 subjects/patients with 307,869 NOAF cases. Mean age ranged from 41.3 to 71.2 years. The prevalence of women ranged from 10.6 to 54.75%. The pooled analysis gave an AUC of .70 (95% CI .66-.74). A subgroup analysis on studies from general population/primary care yielded an AUC of 0.69 (95% CI 0.64-0.75). In the subgroup of patients with cardiovascular disease, the AUC was .71 (.69-.79). The C2HEST score performed similarly in Asian (AUC .72, 95% CI .68-.77), and in Western patients (AUC .68, 95% CI .62-.75). The best performance was observed in studies with a mean age <50 years (n = 3,144,704 with 25,538 NOAF, AUC .78, 95% CI .76-.79). CONCLUSION: The C2HEST score may be used to predict NOAF in primary and secondary prevention patients, and in patients across different countries. Early detection of NOAF may aid prompt initiation of management and follow-up, potentially leading to a reduction of AF-related complications.

The Modified Risk of Paradoxical Embolism Score Is Associated with Patent Foramen Ovale in Patients with Ischemic Stroke: A Nationwide US Analysis.

BACKGROUND: The Risk of Paradoxical Embolism (RoPE) score was developed to identify stroke-related patent foramen ovale (PFO) in patients with cryptogenic stroke. METHODS: We conducted a retrospective analysis of the 2016 to 2020 National Inpatient Sample to determine the performance of the modified RoPE score in identifying the presence of a PFO in patients with acute ischemic stroke (AIS). RESULTS: A total of 3,338,805 hospital admissions for AIS were analysed and 3.0% had PFO. Patients with PFO were younger compared to those without a PFO (median 63 years vs. 71 years, p < 0.001) and fewer were female (46.1% vs. 49.7%, p < 0.001). The patients with PFO had greater mean modified RoPE scores (4.0 vs. 3.3, p < 0.001). The area under the curve for the RoPE score in predicting PFOs was 0.625 (95%CI 0.620-0.629). The best diagnostic power of the RoPE score was achieved with a cut-off point of ≥4 where the sensitivity was 55% and the specificity was 64.2%. A cut-off point of ≥5 increased the specificity (83.1%) at the expense of sensitivity (35.8%). The strongest predictor of PFOs was deep vein thrombosis (OR 3.97, 95%CI 3.76-4.20). CONCLUSIONS: The modified RoPE score had modest predictive value in identifying patients with PFO among patients admitted with AIS.
