Flecainide to Prevent Atrial Arrhythmia after Patent Foramen Ovale Closure, the AFLOAT Study: A Randomized Clinical Trial.

BACKGROUND: The real incidence of atrial arrhythmia (AA) after patent foramen ovale (PFO) closure and whether this complication can be prevented remain unknown. This study assessed if flecainide is effective to prevent AA during the first 3 months after PFO closure, and if 6 months treatment by flecainide is more effective than 3 months to prevent AA after PFO closure. METHODS: AFLOAT is a prospective, multicentre, randomized, open-label, superiority trial with a blind evaluation of all the endpoints (PROBE design). Patients were randomized in a 1:1:1 ratio after PFO closure to receive flecainide (150 mg once a day in a sustained-release (SR) dose) for 3 months, flecainide (150 mg od SR dose) for 6 months, or no additional treatment (standard-of-care) for 6 months. The primary endpoint was the percentage of patients with at least one episode AA (≥30s) recorded within 3 months after PFO closure on long-term monitoring with an insertable cardiac monitor (ICM). The secondary endpoint was the percentage of patients with at least one episode of AA (≥30s) recorded with ICM during the 3-6 months period after PFO closure. RESULTS: 186 patients were included (mean age 54 years, male 68.8%) and AA (≥30s) occurred in 53 (28.5%) patients during the 6-month follow-up; 86.8% of these AA events occurred in the first month after PFO closure. The primary outcome occurred in 33/123 (26.8%) and 16/63 (25.4%) patients receiving flecainide for at least 3 months or standard of care, respectively [Risk Difference (RD) 1.4%; 95% confidence interval (CI) -12.9% to 13.8%, NS]. The secondary endpoint occurred in 3/60 (5.0%), 4/63 (6.3%), and 5/63 (7.9%) patients receiving flecainide 6 months, 3 months or standard of care, respectively [RD -2.9%; 95% CI -12.7% to 6.9%, and RD -1.6%; 95% CI -11.8% to 8.6%, respectively]. CONCLUSIONS: In the first 6 months following successful PFO closure, AA (≥30s) occurred in 28.5% of cases, mostly in the first month after the procedure. Flecainide did not prevent AA after PFO closure.

Prognostic impact of high-intensity lipid-lowering therapy under-prescription after acute myocardial infarction in women.

AIMS: Women are less likely to receive lipid-lowering therapy (LLT) after acute myocardial infarction (AMI). We analysed whether this under-prescription currently persists and has an impact on long-term outcomes. METHODS AND RESULTS: The FAST-MI programme consists of nationwide registries including all patients admitted for AMI ≤ 48 h from onset over a 1 month period in 2005, 2010, and 2015, with long-term follow-up. This analysis focused on high-intensity LLT (atorvastatin ≥ 40 mg or equivalent, or any combination of statin and ezetimibe) in women and men. Women accounted for 28% (N = 3547) of the 12 659 patients. At discharge, high-intensity LLT was significantly less prescribed in women [54 vs. 68% in men, P < 0.001, adjusted odds ratio (OR) 0.78(95% confidence interval (CI) 0.71-0.87)], a trend that did not improve over time: 2005, 25 vs. 35% (P = 0.14); 2010, 66 vs. 79% (P < 0.001); 2015, 67 vs. 79.5% (P = 0.001). In contrast, female sex was not associated with a lack of other recommended treatments at discharge: beta-blockers [adjusted OR 0.98(95% CI 0.88-1.10), P = 0.78], or renin-angiotensin blockers [adjusted OR 0.94(95% CI 0.85-1.03), P = 0.18]. High-intensity LLT at discharge was significantly associated with improved 5 year survival and infarct- and stroke-free survival in women [adjusted hazard ratios (HR) 0.74(95% CI 0.64-0.86), P < 0.001 and adjusted HR: 0.81(95% CI: 0.74-0.89); P < 0.001, respectively]. Similar results were found using a propensity score-matched analysis [HR for 5 year survival in women with high-intensity LLT: 0.82(95% CI 0.70-0.98), P = 0.03]. CONCLUSION: Women suffer from a bias regarding the prescription of high-intensity LLT after AMI, which did not attenuate between 2005 and 2015, with potential consequences on both survival and risk of cardiovascular events.

Lipid-lowering therapy (LLT) is under-prescribed in women after acute myocardial infarction (AMI). Whether this difference persists over time and influences long-term outcomes is unclear. Women still suffer from insufficient prescription of high-intensity LLT at discharge after an AMI, even in the most recent years of the study, with a 5 year survival significantly reduced in women who did not receive high-dose LLT Propensity score matched analysis showed similar results on survival and cardiovascular events.

Sex and the Risk of Atheromatous and Nonatheromatous Cardiovascular Disease in CKD: Findings From the CKD-REIN Cohort Study.

RATIONALE & OBJECTIVE: Sex differences in cardiovascular disease (CVD) are well established, but whether chronic kidney disease (CKD) modifies these risk differences and whether they differ between atheromatous CVD (ACVD) and nonatheromatous CVD (NACVD) is unknown. Assessing this interaction was the principal goal of this study. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: Adults enrolled in the CKD-REIN (CKD-Renal Epidemiology and Information Network) cohort, a nationally representative sample of 40 nephrology clinics in France, from 2013 to 2020. EXPOSURE: Sex. OUTCOMES: Fatal and nonfatal composite ACVD events (ischemic coronary, cerebral, and peripheral artery disease) and composite NACVD events (heart failure, hemorrhagic stroke, and arrhythmias). ANALYTICAL APPROACH: Multivariable cause-specific Cox proportional hazards models. RESULTS: 1,044 women and 1,976 men with moderate to severe CKD (median age, 67 vs 69y; mean estimated glomerular filtration rate [eGFR], 32±12 vs 33±12mL/min/1.73m2) were studied. During a median follow-up of 5.0 (IQR, 4.8-5.2) years, the ACVD rate (per 100 patient-years) was significantly lower in women than in men, at 2.1 (95% CI, 1.6-2.5) versus 3.6 (3.2-4.0; P<0.01), whereas the NACVD rate was not, at 5.7 (5.0-6.5) versus 6.4 (5.8-7.0; P=0.55). NACVD had a steeper relationship with eGFR than did ACVD. There was an interaction (P<0.01) between sex and baseline eGFR and the ACVD hazard: the adjusted HR for women versus men was 0.42 (0.25-0.71) at 45mL/min/1.73m2 and gradually attenuated at lower levels of eGFR, reaching 1.00 (0.62-1.63) at 16mL/min/1.73m2. In contrast, the NACVD hazard did not differ between sexes across the eGFR range studied. LIMITATIONS: Cardiovascular biomarkers and sex hormones were not assessed. CONCLUSIONS: This study shows how the lower risk of ACVD among women versus men attenuates fully with kidney disease progression. The equal risk of NACVD between sexes across CKD stages and its steeper association with eGFR suggest an important contribution of CKD to the development of this CVD type. PLAIN-LANGUAGE SUMMARY: Sex differences in the risks of atheromatous and nonatheromatous cardiovascular disease (CVD) are well established in the general population. If or how chronic kidney disease (CKD) might modify these risks is unknown. In this large cohort of 3,010 patients with CKD, women had a lower risk than men of atheromatous CVDs such as coronary artery disease or stroke when they were at an early stage of CKD. This advantage, partly due to women's better cardiovascular risk profile, tended to attenuate as CKD progressed to kidney failure. In contrast, the risk of nonatheromatous CVDs such as heart failure for women with CKD appeared similar to that of men with CKD at all kidney function levels.

Tricuspid annular plane systolic excursion over systolic pulmonary artery pressure prognostic value for in-hospital adverse events in patients hospitalized for acute coronary syndrome.

AIMS: Although several studies have shown that the right ventricular to pulmonary artery (RV-PA) coupling, assessed by the ratio between tricuspid annular plane systolic excursion and systolic pulmonary artery pressure (TAPSE/sPAP) using echocardiography, is strongly associated with cardiovascular events, its prognostic value is not established in acute coronary syndrome (ACS). We aimed to assess the in-hospital prognostic value of TAPSE/sPAP among patients hospitalized for ACS in a retrospective analysis from the prospective ADDICT-ICCU study. METHODS AND RESULTS: A total of 481 consecutive patients hospitalized in intensive cardiac care unit [mean age 65 ± 13 years, 73% of male, 46% ST-elevation myocardial infarction (STEMI)] for ACS [either STEMI or non-STEMI (NSTEMI)] with TAPSE/sPAP available were included in this prospective French multicentric study (39 centres). The primary outcome was in-hospital major adverse cardiovascular events (MACEs) defined as all-cause death, resuscitated cardiac arrest, or cardiogenic shock and occurred in 33 (7%) patients. Receiver operating characteristic curve analysis identified 0.55 mm/mmHg as the best TAPSE/sPAP cut-off to predict in-hospital MACEs. TAPSE/sPAP <0.55 was associated with in-hospital MACEs, even after adjustment with comorbidities [odds ratio (OR): 19.1, 95% confidence interval (CI) 7.78-54.8], clinical severity including left ventricular ejection fraction (OR: 14.4, 95% CI 5.70-41.7), and propensity-matched population analysis (OR: 22.8, 95% CI 7.83-97.2, all P < 0.001). After adjustment, TAPSE/sPAP <0.55 showed the best improvement in model discrimination and reclassification above traditional prognosticators (C-statistic improvement: 0.16; global χ2 improvement: 52.8; likelihood ratio test P < 0.001) with similar results for both STEMI and NSTEMI subgroups. CONCLUSION: A low RV-PA coupling defined as TAPSE/sPAP ratio <0.55 was independently associated with in-hospital MACEs and provided incremental prognostic value over traditional prognosticators in patients hospitalized for ACS.

In-hospital prognosis of acute ST-elevation myocardial infarction in patients with recent recreational drug use.

AIMS: Although recreational drug use may induce ST-elevated myocardial infarction (STEMI), its prevalence in patients hospitalized in intensive cardiac care units (ICCUs), as well as its short-term cardiovascular consequences, remains unknown. We aimed to assess the in-hospital prognosis of STEMI in patients with recreational drug use from the ADDICT-ICCU study. METHODS AND RESULTS: From 7-22 April 2021, recreational drug use was detected prospectively by a systematic urine multidrug test in all consecutive patients admitted for STEMI in 39 ICCUs across France. The primary endpoint was major adverse cardiac events (MACEs) defined by death, resuscitated cardiac arrest, or cardiogenic shock. Among the 325 patients (age 62 ± 13 years, 79% men), 41 (12.6%) had a positive multidrug test (cannabis: 11.1%, opioids: 4.6%, cocaine: 1.2%, 3,4-methylenedioxymethamphetamine: 0.6%). The prevalence increased to 34.0% in patients under 50 years of age. Recreational drug users were more frequently men (93% vs. 77%, p = 0.02), younger (50 ± 12 years vs. 63 ± 13 years, P < 0.001), and more active smokers (78% vs. 34%, P < 0.001). During hospitalization, 17 MACEs occurred (5.2%), including 6 deaths (1.8%), 10 cardiogenic shocks (3.1%), and 7 resuscitated cardiac arrests (2.2%). Major adverse cardiac events (17.1% vs. 3.5%, P < 0.001) and ventricular arrhythmia (9.8% vs. 1.4%, P = 0.01) were more frequent in recreational drug users. Use of recreational drugs was associated with more MACEs after adjustment for comorbidities (odds ratio = 13.1; 95% confidence interval: 3.4-54.6). CONCLUSION: In patients with STEMI, recreational drug use is prevalent, especially in patients under 50 years of age, and is independently associated with an increase of MACEs with more ventricular arrhythmia.

Flecainide to prevent atrial arrhythmia after patent foramen ovale closure, Rationale and design of the randomized AFLOAT study.

INTRODUCTION: Atrial arrhythmia is the most common complication of patent foramen ovale (PFO) closure. The real incidence of post-PFO closure atrial arrhytmia and whether this complication can be prevented is unknown. METHODS/DESIGN: The Assessment of Flecainide to Lower the PFO closure risk of Atrial fibrillation or Tachycardia (AFLOAT) trial is a prospective, national, multicentre, randomized, open-label, superiority trial with a blind evaluation of all the endpoints (PROBE design). A total of 186 patients are randomized in a 1:1:1 ratio immediately after PFO closure to receive Flecainide (150 mg per day in a single sustained-release (SR) dose) for 6 months (Group 1), Flecainide (150 mg per day in a single SR dose) for 3 months (Group 2), or no additional treatment (standard of care) for 6 months (Group 3). The primary endpoint is the percentage of patients with at least one episode of symptomatic or asymptomatic atrial arrhythmia episode (≥30 s) recorded within 3 months after PFO closure on long-term monitoring with an insertable cardiac monitor. Whether 3 months of treatment is sufficient compared to 6 months will be analysed as a secondary objective of the study. CONCLUSION: AFLOAT is the first trial to test the hypothesis that a short treatment with oral Flecainide can prevent the new-onset of atrial arrhythmia after PFO closure.

Comparison of three echo-guidance techniques in percutaneous patent foramen ovale closure for stroke prevention: Conventional transoesophageal, microprobe transoesophageal and intracardiac echocardiography.

BACKGROUND: Recent randomized trials have demonstrated a consistent reduction in recurrent stroke after percutaneous transcatheter patent foramen ovale closure versus medical therapy in patients with recent cryptogenic stroke. AIM: To compare the safety and efficacy of intracardiac echocardiography-guided and microprobe transoesophageal echocardiography-guided patent foramen ovale closure under local anaesthesia with transoesophageal echocardiography-guided patent foramen ovale closure under general anaesthesia. METHODS: This prospective observational single-centre study included 194 consecutive patients scheduled for patent foramen ovale closure for secondary prevention of stroke from February 2018 to December 2019. Patients were asked to choose between an intracardiac echocardiography-guided, microprobe transoesophageal echocardiography-guided or transoesophageal echocardiography-guided procedure. The primary endpoint was the rate of successful closure at 6 months, defined as correct positioning of the device without severe shunt on 6-month contrast echocardiography. RESULTS: Successful closure was high and did not differ between groups: 97.8% (95% confidence interval 88.5-99.9%) in the intracardiac echocardiography-guided group versus 96.9% (95% confidence interval 83.8-99.9%) in the microprobe transoesophageal echocardiography-guided group and 99.1% (95% confidence interval 95.3-99.9%) in the transoesophageal echocardiography-guided group (P=0.63). Adverse events related to patent foramen ovale closure were low and did not differ between groups. CONCLUSION: Our preliminary real-world experience suggests good efficacy and safety with intracardiac echocardiography and microprobe transoesophageal echocardiography guidance compared with conventional transoesophageal echocardiography guidance for percutaneous transcatheter patent foramen ovale closure in recurrent stroke prevention.

Rationale and design of the ARAMIS trial: Anakinra versus placebo, a double blind randomized controlled trial for the treatment of acute myocarditis.

BACKGROUND: Acute myocarditis is an inflammation of the myocardium that can cause life-threatening events. However, anti-inflammatory strategies did not reduce the risk of clinical outcomes in randomized trials. Recently, experimental studies have suggested that specific blockade of the interleukin-1ß immune innate pathway could be effective in acute myocarditis. AIM: To test the hypothesis that inhibition of the interleukin-1ß immune innate pathway can reduce the risk of clinical events in acute myocarditis. METHODS: The "Anakinra versus placebo double blind Randomized controlled trial for the treatment of Acute MyocarditIS" (ARAMIS) trial (ClinicalTrials.gov identifier: NCT03018834) is a national multicentre randomized parallel-group double blind study among symptomatic patients with elevated cardiac troponin and cardiac magnetic resonance-proven acute myocarditis. Patients (n=120) are randomized within 72hours of hospital admission to receive a daily subcutaneous dose of anakinra 100mg or placebo during the hospitalization, in addition to standard of care, including an angiotensin-converting enzyme inhibitor and a beta-blocker. The primary endpoint is the number of days alive free from any myocarditis complication, including ventricular arrhythmias, heart failure, recurrent chest pain requiring medication and ventricular dysfunction (defined as left ventricular ejection fraction<50%), from randomization to 28 days after hospital discharge. At 28 days after discharge, patients with normal left ventricular ejection fraction are then randomized to angiotensin-converting enzyme inhibitor continuation or discontinuation and all patients are followed for 1 year, with regular left ventricular function evaluation. CONCLUSIONS: ARAMIS is the first trial evaluating inhibition of the interleukin-1ß immune innate pathway in the setting of acute myocarditis. Although of small size, it will be the largest randomized trial in acute myocarditis, a serious and poorly studied cardiac condition.

Prevalence of prediabetes and undiagnosed diabetes in a large urban middle-aged population: the CARVAR 92 cohort.

BACKGROUND: The aim of this study was to assess the prevalence of prediabetes and unknown diabetes and its long-term change in a large middle-aged urban population. METHODS: We conducted a screening campaign between 2007 and 2018 for cardiovascular risk factors in the western suburbs of Paris including subjects aged 40-70 (CARVAR 92). Among subjects who reported no previous diabetes, prediabetes and undiagnosed diabetes were defined as follows: fasting plasma glucose (FPG) ≥ 6.1 mmol/l (110 mg/dl) and < 7 mmol/l (126 mg/dl) for prediabetes according to WHO criteria (FPG between 5.6 and 6.9 mmol/l according to ADA criteria) and FPG ≥ 7.0 mmol/l for undiagnosed diabetes. RESULTS: Of the 32,721 subjects in the CARVAR 92 cohort, 32,675 were included in this analysis. The median age of the patients was 56 years [30, 94], 45.4% were male, 5.9% had known diabetes, 36.4% were overweight and 18.7% obese. Among patients without previously known diabetes (n = 30,759), 8.1% had prediabetes according to WHO criteria (27.2% according to ADA criteria) and 2.3% had diabetes. Subjects with prediabetes and unknown diabetes were more likely to be male, older, and overweight or obese than non-diabetic subjects. From 2007 to 2018, the prevalence of prediabetes, unknown diabetes, and known diabetes decreased, except for prediabetes which remained stable for people aged 55-64. CONCLUSION: The prevalence of prediabetes and unknown diabetes remains high but decreased during a 12-year period. About one-quarter of diabetes cases remain undiagnosed. Our results highlight that there is still a room for screening and cardiovascular prevention campaigns. TRIAL REGISTRATION: IRB00012437.

Electrocardiogram abnormalities and prognosis in COVID-19.

Background: COVID-19 is a major pandemic with potential cardiovascular complications. Few studies have focused on electrocardiogram (ECG) modifications in COVID-19 patients. Method and results: We reviewed from our database all patients referred to our hospital for COVID-19 between January 1st, 2020, and December 31st, 2020: 669 patients were included and 98 patients died from COVID-19 (14.6%). We systematically analyzed ECG at admission and during hospitalization if available. ECG was abnormal at admission in 478 patients (71.4%) and was more frequently abnormal in patients who did not survive (88.8 vs. 68.5%, p < 0.001). The most common ECG abnormalities associated with death were left anterior fascicular block (39.8 vs. 20.0% among alive patients, p < 0.001), left and right bundle branch blocks (p = 0.002 and p = 0.02, respectively), S1Q3 pattern (14.3 vs. 6.0%, p = 0.006). In multivariate analysis, at admission, the presence of left bundle branch block remained statistically related to death [OR = 3.82, 95% confidence interval (CI): 1.52-9.28, p < 0.01], as well as S1Q3 pattern (OR = 3.17, 95% CI: 1.38-7.03, p < 0.01) and repolarization abnormalities (OR = 2.41, 95% CI: 1.40-4.14, p < 0.01).On ECG performed during hospitalization, the occurrence of new repolarization abnormality was significantly related to death (OR = 2.72, 95% CI: 1.14-6.54, p = 0.02), as well as a new S1Q3 pattern (OR = 13.23, 95% CI: 1.49-286.56, p = 0.03) and new supraventricular arrhythmia (OR = 3.8, 95% CI: 1.11-13.35, p = 0.03). Conclusion: The presence of abnormal ECG during COVID-19 is frequent. Physicians should be aware of the usefulness of ECG for risk stratification during COVID-19.

Supraventricular Arrhythmia Following Patent Foramen Ovale Percutaneous Closure.

BACKGROUND: Randomized studies have reported low rates of atrial fibrillation (AF) after patent foramen ovale (PFO) closure (<6%) but have relied on patient-reported symptomatic episodes, so the true incidence and timing of AF after PFO closure remain unknown. OBJECTIVES: The aim of this study was to prospectively determine the incidence, timing, and determinants of supraventricular arrhythmia following PFO closure on the basis of loop recorder monitoring. METHODS: Cardiac monitoring was proposed to all patients after PFO closure from June 2018 to October 2021 at a single center by means of implantable loop recorder monitoring in patients considered at higher risk for AF (age ≥ 55 years, associated cardiovascular risk factors, prior palpitations, or documented supraventricular ectopic activity) or 4-week external loop recorder monitoring in other patients. The primary endpoint was the incidence of AF, atrial flutter, or supraventricular tachycardia lasting >30 seconds within 28 days of the procedure. Determinants of the primary endpoint were assessed using a stepwise logistic regression model. RESULTS: A total of 225 patients were included. The primary endpoint occurred in 47 patients (20.9%), including 13 (9.9%) and 24 (28.9%) among patients monitored with external loop recorders and implantable loop recorders, respectively. Overall, the median delay from procedure to arrhythmia was 14.0 days (IQR: 6.5-19.0 days), and one-half of these patients reported symptomatic episodes. Determinants of the primary endpoint were older age (adjusted OR: 1.67 per 10-year increase; 95% CI: 1.18-2.36), device left disc diameter ≥25 mm (adjusted OR: 2.67; 95% CI: 1.19-5.98) and male sex (adjusted OR: 4.78; 95% CI: 1.96-11.66). CONCLUSIONS: Using loop recorder monitoring for ≥28 days, supraventricular arrhythmia was diagnosed in 1 in 5 patients, with a median delay of 14 days, suggesting that this postprocedural event has so far been underestimated.

Usefulness of Longitudinal Strain Adjusted to Regional Thickness in Hypertrophic Cardiomyopathy.

Background. We assessed the usefulness of a longitudinal strain adjusted to regional thickness in hypertrophic cardiomyopathy (HCM). Indeed, with conventional software, the width of the region of interest (ROI) is the same over the entire myocardial wall, wherein the software analyzes only partially the left ventricular (LV) hypertrophic segments. Methods. We included 110 patients: 55 patients with HCM (HCM group) and 55 healthy subjects (age- and sex-matched control group). The global longitudinal strain (GLS) and regional strain for each of the 17 segments was calculated with standard software (for two groups) and with software adjusted to the myocardial wall thickness (for the HCM group). Results. GLS was significantly decreased in the HCM group compared to the control group (−15.1 ± 4.8% versus −20.5 ± 4.3%, p < 0.0001). In the HCM group, GLS (standard method versus adjusted to thickness) measurements were not significantly different (p = 0.34). Interestingly, the regional strain adjusted to thickness was significantly lower than the standard strain in the hypertrophic segments, especially in the basal inferoseptal segment (p = 0.0002), median inferoseptal segment (p < 0.001) and median anteroseptal segment (p = 0.02). The strain adjusted to thickness was still significantly lower in the most hypertrophic segments (≥20 mm) (−3.7 ± 3%, versus −5.9 ± 4.4%, p = 0.049 in the basal inferoseptal segment and −5.7 ± 3.5% versus −8.3 ± 4.5%, p = 0.0007 in the median inferoseptal segment). In the segments with significant myocardial fibrosis, the longitudinal strain adjusted to thickness was significantly lower than the conventional strain (−8.3 ± 3.3% versus −11.4 ± 4.5%, p = 0.002). The analysis of the strain adjusted to thickness had a better feasibility (97.5% versus 99%, p = 0.01). Conclusions. The analysis of a longitudinal strain adjusted to regional thickness is feasible in HCM and allows a better evaluation of myocardial deformation, especially in the most LV hypertrophic segments.

Outcomes Following Patent Foramen Ovale Percutaneous Closure According to the Delay From Last Ischemic Event.

BACKGROUND: Randomised controlled trials evaluating percutaneous closure of patent foramen ovale (PFO) have included only patients with a recent embolic event. We aimed to evaluate outcomes after percutaneous PFO closure according to the delay from the last embolic episode. METHODS: This international ambispective cohort included consecutive patients from 2 centres in France and Canada undergoing PFO closure for secondary prevention of a paradoxical embolic event. The primary end point was the composite of stroke or transient ischemic attack (TIA). A logistic regression model was used to evaluate determinants of late PFO closure procedures. RESULTS: A total of 1179 patients (mean age 49 ± 12.7 years; 44.4% female) underwent PFO closure from 2001 to 2021. The median delay from last embolic event to procedure was 6.0 (interquartile range 3.4-11.2) months. The determinants of late PFO closure procedure were the centre (France vs Canada; adjusted odds ratio [aOR] 1.65, 95% confidence interval [CI] 1.25-2.19), year of procedure (since 2018 vs before 2018; aOR 1.43, 95% CI 1.08-1.90), female sex (aOR 1.63, 95% CI 1.28-2.07), and lower risk of paradoxical embolism score (aOR 1.10, 95% CI 1.03-1.19). After a median follow-up of 2.61 (1.13-7.25) years, the incidence rate of first stroke or TIA did not differ between early and late PFO procedures, with 0.51 vs 0.29 events per 100 patient-years, respectively (incidence rate ratio 1.74, 95% CI 0.66-5.08; P = 0.24), and the timing of PFO closure was not associated with the occurrence of stroke or TIA in univariate analysis (hazard ratio 0.54, 95% CI 0.22-1.34) for late vs early closure). CONCLUSIONS: This analysis provides indirect evidence that the delay from the last ischemic event does not affect outcomes after PFO closure for secondary prevention.

Relevance of Cardiovascular Risk Factors Screening in People Aged over 65 Years: Results from a Large French Urban Population (The CARVAR92 Study).

BACKGROUND: Cardiovascular disease is the leading cause of death and disability in older people. Traditional cardiovascular risk factors (CVRFs) still have an impact on cardiovascular risk among older people. Nevertheless, screening campaigns rarely target subjects aged over 65 years. This study aimed to assess the distribution and relevance of conventional CVRF screening in people aged over 65 years. METHODS: Between 2007 and 2018, among a screening CVRF campaign in the western suburbs of Paris (32,692 subjects), we individualized 6,577 subjects aged 65 years and over. All conventional CVRFs have been systematically assessed. RESULTS: The screening allowed to suspect hypertension in a larger proportion of subjects over 65 years compared to subjects under 65 years (27% vs. 18%, p < 0.0001). Hypertension control was higher in women compared to men but not significantly different in the age-groups (p = 0.91). Screening for diabetes mellitus was positive in 3% of older subjects and 2.4% in younger (p = 0.005). Risk assessment with dedicated score (SCORE O.P.) allowed to move toward a low-risk estimation, resulting in the diminution of intermediate risk group in women over 65 years (from 68 to 61%, p < 0.001). CONCLUSIONS: Screening CVRFs especially hypertension remains relevant in people aged over 65 years as it enables to detect unknown CVRFs in numerous subjects. Increasing awareness of CVRFs may be the first step to CVRF control, which is known to be efficient on cardiovascular mortality and functional autonomy in later life.

Prevalence of familial hypercholesterolaemia in patients presenting with premature acute coronary syndrome.

BACKGROUND: Familial hypercholesterolaemia (FH) is responsible for severe hypercholesterolaemia and premature cardiovascular morbidity and mortality. The first clinical event is typically an acute coronary syndrome. Unfortunately, FH is largely underdiagnosed in the general population. AIMS: To assess the prevalence of clinical FH among patients with premature (aged≤50 years) acute myocardial infarction (MI) and compare it with FH prevalence in a control population. METHODS: We reviewed in our database all patients with premature MI (aged≤50 years) referred to Ambroise Paré Hospital from 2014 to 2018. FH prevalence was estimated via the Dutch Lipid Clinic Network score, based on personal and family history of premature cardiovascular disease and low-density lipoprotein cholesterol concentrations. FH was "possible" with a score between 3 and 5 points, "probable" with a score between 6 and 8 and "definite" with a score above 8. FH prevalence in young patients with MI was then compared with FH prevalence in a general population of the same age from the CARVAR 92 prospective cohort. RESULTS: Of the 457 patients with premature MI, 29 (6%) had "probable" or "definite" FH. In the CARVAR 92 cohort, 16 (0.16%) of 9900 subjects aged≤50 years had "probable" or "definite" FH. FH prevalence was 39 times greater among patients with premature MI than in the control population (P<0.0001). In multivariable analysis, FH was strongly associated with MI (adjusted odds ratio 38.4, 95% confidence interval 19.1-79.4). CONCLUSIONS: FH is>30-fold more common in patients referred for premature MI than in the general population; this highlights the need for FH screening after a first MI to enhance lipid-lowering therapy and allow early identification of family members.

Screening of Native Valvular Heart Disease Using a Pocket-Sized Transthoracic Echocardiographic Device.

BACKGROUND: The authors assessed the performance of pocket-sized transthoracic echocardiography (pTTE) compared with standard transthoracic echocardiography (sTTE) and auscultation for early screening of valvular heart disease (VHD). Early diagnosis of significant VHD is a challenge, but it enables appropriate follow-up and implementation of the best therapeutic strategy. METHODS: sTTE, pTTE, and auscultation were performed by three different experienced physicians on 284 unselected patients. All cases of VHD detected by each of these three techniques were noted. sTTE was the gold standard. Each physician performed one examination and was blinded to the results of other examinations. RESULTS: We diagnosed a total of 301 cases of VHD, with a large predominance of regurgitant lesions: 269 cases (89.3%) of regurgitant VHD and 32 (10.7%) of stenotic VHD. pTTE was highly sensitive (85.7%) and specific (97.9%) for screening for VHD, while auscultation detected only 54.1%. All significant cases of VHD (at least mild severity) were detected on pTTE. The weighted κ coefficient between pTTE and sTTE for the assessment of mitral regurgitation was 0.71 (95% CI, 0.70-0.72), indicating good agreement. The weighted κ coefficients between pTTE and sTTE for the assessment of aortic regurgitation and aortic stenosis were 0.97 (95% CI, 0.96-0.98) and 0.98 (95% CI, 0.97-0.99), respectively, indicating excellent agreement. CONCLUSIONS: pTTE performed by physicians with level III competency in echocardiography is reliable for identifying significant VHD and should be proposed as a new screening tool.
