Sex and the Risk of Atheromatous and Non-Atheromatous 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 (ACVD) and non-atheromatous (N-ACVD) CVD is unknown. Assessing this interaction was the principal goal of this study. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: Adults enrolled in the CKD-Renal Epidemiology and Information Network (CKD-REIN) cohort from from 2013 to 2020, a nationally representative sample of 40 nephrology clinics in France. EXPOSURE: Sex. OUTCOMES: Fatal and non-fatal composite ACVD events (ischaemic coronary, cerebral, and peripheral artery disease) and composite N-ACVD events (heart failure, haemorrhagic 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. 69; mean estimated glomerular filtration rate [eGFR], 32±12 vs. 33±12 mL/min/1.73m2) were studied. Over a median follow-up of 5.0 (interquartile range, 4.8;5.2) years, the ACVD rate (per 100 patient-years) was significantly lower in women than men: 2.1 (95% confidence interval: 1.6-2.5) vs 3.6 (3.2-4.0) (P<0.01), while the N-ACVD rate was not: 5.7 (5.0-6.5) vs 6.4 (5.8-7.0) (P=0.55). N-ACVD 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 hazard ratio for women compared to men was 0.42 (0.25;0.71) at 45 mL/min/1.73m2 and gradually attenuated at lower levels of eGFR, reaching 1.00 (0.62;1.63) at 16 mL/min/1.73m2. In contrast, the N-ACVD hazard did not differ between the sexes across the eGFR range studied. LIMITATIONS: Cardiovascular biomarkers and sex hormones were not assessed. CONCLUSION: This study shows how the lower risk of ACVD among women compared to men attenuates fully with kidney disease progression. The equal risk of N-ACVD between sexes across CKD stages and its steeper association with eGFR suggest an important contribution of CKD to the development of this CVD type.

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.

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.

Impact of chronic total occlusion and revascularization strategy in patients with infarct-related cardiogenic shock: A subanalysis of the culprit-shock trial.

BACKGROUND: The impact of coronary artery chronic total occlusion (CTO) and its management with percutaneous coronary intervention (PCI) in the setting of myocardial infarction (MI) related cardiogenic shock (CS) remains unclear. METHODS: This is a pre-specified analysis from the culprit-lesion-only PCI vs multivessel PCI in CS (CULPRIT-SHOCK) trial which randomized patients presenting with MI and multivessel disease complicated by CS to a culprit-lesion-only or immediate multivessel PCI strategy. CTO was defined by central core-laboratory evaluation. The independent associations between the presence of CTO and adverse outcomes at 30 days and 1 year were assessed using multivariate logistics models. RESULTS: A noninfarct related CTO was present in 157 of 667 (23.5%) analyzed patients. Patients presenting with CTO had more frequent diabetes mellitus or prior PCI but less frequently presented with ST segment elevation MI as index event. The presence of CTO was associated with higher rate of death at 30 days (adjusted Odds ratio 1.63; 95% confidence interval [CI] 1.01-2.60). Rate of death at 1 year was also increased but did not reach statistical significance (adjusted Odds ratio 1.62; 95%CI 0.99-2.66). Compare to immediate multivessel PCI, a strategy of culprit-lesion-only PCI was associated with lower rates of death or renal replacement therapy at 30 days in patients with and without CTO (Odds ratio 0.79 95%CI 0.42-1.49 and Odds ratio 0.67 95%CI 0.48-0.96, respectively), without significant interaction (P = .68). CONCLUSIONS: In patients with MI-related CS and multivessel disease, the presence of CTO is associated with adverse outcomes while a strategy of culprit-lesion-only PCI seems beneficial regardless of the presence of CTO.

Occurrence of pulmonary embolism related to COVID-19.

Recent reports have suggested an increased risk of pulmonary embolism (PE) related to COVID-19. The aim of this cohort study is to compare the incidence of PE during a 3-year period and to assess the characteristics of PE in COVID-19. We studied consecutive patients presenting with PE (January 2017-April 2020). Clinical presentation, computed tomography (CT) and biological markers were systematically assessed. We recorded the global number of hospitalizations during the COVID-19 pandemic and during the same period in 2018-2019. We included 347 patients: 326 without COVID-19 and 21 with COVID-19. Patients with COVID-19 experienced more likely dyspnea (p=0.04), had lower arterial oxygen saturation (p<0.001), higher C-reactive protein and white blood cell (WBC) count (p<0.0001 and p=0.001, respectively), and a significantly higher in-hospital mortality (14% versus 3.4%, p=0.04). Among COVID-19 patients, diagnosis of PE was performed at admission in 38% (n=8). COVID-19 patients with diagnosis of PE during hospitalization (n=13) had significantly more dyspnea (p=0.04), lower arterial oxygen saturation (p=0.01), less proximal PE (p=0.02), and higher heart rate (p=0.009), CT severity score (p=0.001), C-reactive protein (p=0.006) and WBC count (p=0.04). During the COVID-19 outbreak, a 97.4% increase of PE incidence was observed as compared to 2017-2019 and the proportion of hospitalizations related to PE was 3.7% versus 1.3% in 2018-2019 (p<0.0001). In conclusion, the COVID-19 pandemic leads to a dramatic increased incidence of PE. Physicians should be aware that PE may be diagnosed at admission, but also after several days of hospitalization, with a different clinical, CT and biological features of thrombotic disease.

Impact of Coronavirus Disease 2019 outbreak on acute coronary syndrome admissions: four weeks to reverse the trend.

Data whether the COVID-19 outbreak impacts the acute coronary syndromes (ACS) admissions and the time required to reverse the downward curve are scarce. We included all consecutive patients referred for an ACS who underwent PCI from February 17, 2020 to April 26, 2020 in a high-volume PCI coronary care unit. We compared the number of ACS patients in 2020 to the same period in 2018 and 2019. Predictors of adverse outcome in ST-elevation myocardial infarction (STEMI) patients were recorded: symptom-onset-to-first medical contact (FMC), and FMC-to-sheath insertion times. During the studied period (calendar weeks 8-17, 2018-2020), 144 ACS patients were included. In 2020, we observed two distinct phases in the ACS admissions: a first significant fall, with a relative reduction of 73%, from the week of lockdown (week 12) to 3 weeks later and then an increase of ACS. Median symptom-onset-to-FMC time was significantly higher in 2020 than in the two previous years (600 min [298-632] versus 121 min [55-291], p < 0.001). Median FMC-to-sheath insertion did not differ significantly (93 min [81-131] in 2020 versus 90 min [67-137] in 2018-2019, p = 0.57). The main findings are (1) a pattern of a U-curve in ACS admissions, with a first decrease in ACS admissions and a return to "normality" 4 weeks after; (2) a significant increase in the total ischemic time exclusively due to an increase in the symptom-onset-to-first-medical-contact time.

[Interventional cardiology in the elderly, at the time of TAVI and left atrial appendage occlusion]. / Cardiologie interventionnelle chez le sujet âgé.

Interventional cardiology is increasingly being offered to frail elderly people thanks to significant technical progress. Transcatheter aortic valve implantation allows the treatment of aortic stenosis by implanting an aortic bioprosthesis through a catheter, without surgery. The left atrial appendage occlusion limits the risk of ischemic stroke in patients with atrial fibrillation who have a contraindication to anticoagulants. These procedures remain invasive and must be proposed after multidisciplinary consultation.

Radial versus femoral artery access for percutaneous coronary artery intervention in patients with acute myocardial infarction and multivessel disease complicated by cardiogenic shock: Subanalysis from the CULPRIT-SHOCK trial.

BACKGROUND: The use and impact of transradial artery access (TRA) compared to transfemoral artery access (TFA) in patients undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (MI) complicated by cardiogenic shock (CS) remain unclear. METHODS: This is a post hoc analysis of the CULPRIT-SHOCK trial where patients presenting with MI and multivessel disease complicated by CS were randomized to a strategy of culprit-lesion-only or immediate multivessel PCI. Arterial access was left at operator's discretion. Adjudicated outcomes of interest were the composite of death or renal replacement therapy (RRT) at 30 days and 1 year. Multivariate logistic models were used to assess the association between the arterial access and outcomes. RESULTS: Among the 673 analyzed patients, TRA and TFA were successfully performed in 118 (17.5%) and 555 (82.5%) patients, respectively. Compared to TFA, TRA was associated with a lower 30-day rate of death or RRT (37.3% vs 53.2%, adjusted odds ratio [aOR]: 0.57; 95% confidence interval [CI] 0.34-0.96), a lower 30-day rate of death (34.7% vs 49.7%; aOR: 0.56; 95% CI 0.33-0.96), and a lower 30-day rate of RRT (5.9% vs 15.9%; aOR: 0.40; 95% CI 0.16-0.97). No significant differences were observed regarding the 30-day risks of type 3 or 5 Bleeding Academic Research Consortium bleeding and stroke. The observed reduction of death or RRT and death with TRA was no longer significant at 1 year (44.9% vs 57.8%; aOR: 0.85; 95% CI 0.50-1.45 and 42.4% vs 55.5%, aOR: 0.78; 95% CI 0.46-1.32, respectively). CONCLUSIONS: In patients undergoing PCI for acute MI complicated by CS, TRA may be associated with improved early outcomes, although the reason for this finding needs further research.

Blunting periprocedural myocardial necrosis: Rationale and design of the randomized ALPHEUS study.

BACKGROUND: Clopidogrel associated with aspirin is the recommended treatment for patients undergoing elective percutaneous coronary intervention (PCI). Although severe PCI-related events are rare, evidence suggests that PCI-related myocardial infarction and myocardial injury are frequent complications that can impact the clinical prognosis of the patients. Antiplatelet therapy with a potent P2Y12 receptor inhibitor such as ticagrelor may reduce periprocedural ischemic complications while maintaining a similar safety profile as compared with conventional dual antiplatelet therapy by aspirin and clopidogrel in this setting. METHODS: Assessment of Loading with the P2Y12 inhibitor ticagrelor or clopidogrel to Halt ischemic Events in patients Undergoing elective coronary Stenting (ALPHEUS) (NCT02617290) is an international, multicenter, randomized, parallel-group, open-label study in patients with stable coronary artery disease who are planned for an elective PCI. In total, 1,900 patients will be randomized before a planned PCI to a loading dose of ticagrelor 180 mg or a loading dose of clopidogrel (300 or 600 mg) in addition to aspirin. Patients will then receive a dual antiplatelet therapy with aspirin and ticagrelor 90 mg twice daily or clopidogrel 75 mg once daily for 30 days. The primary ischemic end point is PCI-related myocardial infarction (myocardial infarction type 4a or 4b) or major myocardial injury within 48 hours (or at hospital discharge if earlier) after elective PCI/stent. Safety will be evaluated by major bleeding events (Bleeding Academic Research Consortium type 3 or 5) at 48 hours (or discharge if it occurs earlier). CONCLUSION: ALPHEUS is the first properly sized trial comparing ticagrelor to clopidogrel in the setting of elective PCI and is especially designed to show a reduction in periprocedural events, a surrogate end point for mortality.

Periprocedural myocardial infarction and injury in elective coronary stenting.

Aims: To assess the incidence, risk factors and prognosis of periprocedural myocardial infarction (MI) and myocardial injury in patients undergoing elective percutaneous coronary intervention (PCI). Methods and results: We included all consecutive patients who underwent elective PCI with a negative troponin level at admission from 1 January 2014 to 31 December 2015. The primary endpoint was defined as the composite of periprocedural MI (Type 4a MI), stent thrombosis (Type 4b MI), and myocardial injury according to the Third universal definition of MI. Multivariable analysis was performed to identify independent predictors of periprocedural MI and myocardial injury and its relation to 30-day and 1-year clinical outcome. Of the 1390 elective PCI patients, the primary endpoint occurred in 28.7% of patients, including 7.0% of Type 4a MI, 0.14% of Type 4b MI, and 21.6% of myocardial injury. Independent risk factors for the occurrence of the primary endpoint were left main PCI, total stent length >30 mm, multiple stenting, chronic kidney disease (estimated glomerular filtration rate <60 mL/min) and age >75 years. At 30 days, patients with periprocedural MI and myocardial injury had a higher rate of cardiovascular events [5.5% vs. 1.2%, adjusted hazard ratio (adjHR) = 3.8, 95% confidence interval (CI) 1.9-6.9; P < 0.001] mainly driven by ischaemic events (3.2% vs. 0.6%, HR 5.9, 95% CI 2.9-20; P < 0.0001). At 1-year, the risk of ischemic events remained higher in the periprocedural MI and myocardial injury group (adjHR = 1.7, 95% CI 1.1-2.6; P = 0.004). Conclusions: Periprocedural MI and injury are frequent complications of elective PCI associated with an increased rate of cardiovascular events at 30 days and 1 year.

Platelet reactivity in human immunodeficiency virus infected patients on dual antiplatelet therapy for an acute coronary syndrome: the EVERE2ST-HIV study.

AIM: To explore platelet reactivity on dual antiplatelet therapy (DAPT) of acute coronary syndrome (ACS) patients infected with HIV. METHODS AND RESULTS: Acute coronary syndrome patients infected with HIV (n = 80) were matched to ACS patients without HIV (n = 160) on age, sex, diabetes, and DAPT (aspirin 100%, clopidogrel 68%, prasugrel 31%, ticagrelor 1%). Platelet reactivity was evaluated after ACS (>30 days) by measuring residual platelet aggregation (RPA) to aspirin and to P2Y12 inhibitors with light transmission aggregometry (LTA), VerifyNow aspirin assay (ARU), and P2Y12 assay (PRU) and with the VASP platelet reactivity index (VASP-PRI). Proportion of patients with high residual platelet reactivity (HPR) was evaluated. HIV-infected ACS patients had higher levels of platelet reactivity in response to P2Y12 inhibitors (RPA: 23.8 ± 2.7% vs. 15.3 ± 1.3%; P = 0.001; PRU: 132 ± 10 vs. 107.4 ± 6.6; P = 0.04; and VASP-PRI: 45.2 ± 2.6% vs. 32.0 ± 2.0%; P < 0.001) and to aspirin (RPA: 3.6 ± 1.5% vs. 0.4 ± 0.1%; P = 0.004 and ARU: 442 ± 11 vs. 407 ± 5; P = 0.002) compared with non-HIV. HIV-infection was independently associated with increased platelet reactivity regardless of the test used (RPA: P = 0.005; PRU: P < 0.001 and VASP-PRI: P < 0.001) and a higher proportion of HPR (OR = 7.6; P < 0.001; OR = 2.06; P = 0.06; OR = 2.91; P = 0.004, respectively) in response to P2Y12 inhibitors. Similar results were found with aspirin. Protease inhibitors use was associated with increased platelet reactivity and higher rate of HPR. CONCLUSIONS: Acute coronary syndrome patients infected with HIV have increased levels of platelet reactivity and higher prevalence of HPR to P2Y12 inhibitors and aspirin than non-HIV patients. These results could provide potential explanations for the observed increase risk of recurrent ischemic events in the HIV-infected population.

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.

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.

TAPSE/sPAP 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: 481 consecutive patients hospitalized in intensive cardiac care unit (mean age 65±13 years, 73% of male, 46% STEMI) for ACS (either ST-elevation [STEMI] or non-ST-elevation [NSTEMI] myocardial infarction) with TAPSE/sPAP available were included in this prospective French multicentric study (39 centers). 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. ROC-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 (OR:19.1, 95%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 chi-square improvement: 52.8; LR-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.

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.

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.

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.

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.

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.
