Acute coronary syndrome in patients treated by vitamin K antagonists or non-vitamin K antagonist oral anticoagulants: Proposed management algorithm for the first 48hours.

Around 10% of patients with acute coronary syndrome are treated by vitamin K antagonists or non-vitamin K antagonist oral anticoagulants for various indications. The initial management of these patients is highly complex, and new guidelines specify that, only during percutaneous coronary intervention, a bolus of unfractionated heparin is recommended in one of the following circumstances: (1) if the patient is receiving a non-vitamin K antagonist oral anticoagulant; or (2) if the international normalized ratio is<2.5 in a patient being treated with a vitamin K antagonist. In this review, we report on five key messages essential for the management of these patients. There are no randomized studies to date, and we propose two diagnostic and/or therapeutic decision algorithms. However, randomized studies are needed to validate these strategies.

Characteristics and prognosis of patients with elevated triglycerides in acute myocardial infarction: observational data from a large database over a 17-year period: High triglycerides in acute myocardial infarction.

From a large regional registry, we aimed to address the characteristics and prognosis of patients with elevated triglycerides (TG) among patients hospitalized for an acute myocardial infarction (MI). From the multicenter database of the RICO survey, all consecutive patients hospitalized for an acute MI (2001-2017) and alive at discharge were included. Among the 10,667 patients included, 17.7% had elevated TG. When compared with patients with TG ≤ 200 mg/dL, patients with high TG (>200 mg/dL) were 10 years younger, had a higher BMI, were more frequently men, diabetic, and smokers. At 1-year follow-up, recurrent ischemic events were more frequent in elevated TG patients. In multivariate logistic regression analysis, high TG (OR (95%CI): 1.356 (1.095-1.679)) remained an independent estimate for recurrent ischemic events, even after adjustment for confounding factors. In our large population-based cohort, elevated TG are common in acute MI, and associated with residual risk of recurrent ischemic events, beyond traditional prognostic markers.

Diagnostic and prognostic impact of new pathophysiology-based categorization of type 1 and type 2 myocardial infarction: data from the French RICO survey.

BACKGROUND: A new classification of type 1 and 2 myocardial infarction (MI) derived from the fourth universal definition of MI (UDMI) has been recently proposed, based on pathophysiology of coronary artery disease (CAD). We assessed the impact of this new MI categorization on epidemiology and outcomes, considering type 1 MI (T1MI) and type 2 MI (T2MI), with and without CAD. METHODS: Retrospective study including all consecutive patients hospitalized for an acute MI in a multicenter database (RICO). MI was defined according to current UDMI. Rates and outcomes of T1MI and T2MI were addressed according to the new classification. RESULTS: Among the 4,573 patients included in our study, 3,710 patients (81.1%) were initially diagnosed with T1M1 and 863 (18.9%) with T2MI. After reclassification, 96 T2MI patients were moved into the T1MI category. Out of the remaining 767 patients with T2MI, 567 underwent coronary angiography, and were adjudicated as type 2A MI (68.6%) with obstructive CAD, and type 2B MI (31.4%) without obstructive CAD. When compared with T1MI and T2BMI, T2AMI patients had worse in-hospital outcomes, including severe heart failure (P < .001), atrial fibrillation or flutter (P < .001) and severe bleeding (P < .001). Kaplan-Meier 1-year survival curves showed higher all-cause and CV causes mortality in T2AMI patients compared to T1MI and T2BMI (P < .001). In multivariate Cox regression analysis, type of MI was independent predictor of death. CONCLUSION: Our large observational multicenter study shows major disparities in mortality according to type of MI and support the relevance of the new MI classification to improve risk classification, taking into account CAD in T2MI. Our findings may help identifying specific phenotypes and considering personalized diagnostic and management strategies.

Nephrotic syndrome and acute coronary syndrome in children, teenagers and young adults: Systematic literature review.

Myocardial infarction is rare in children, teenagers and young adults (aged<20 years). The most common aetiologies identified include Kawasaki disease, familial hypercholesterolaemia, collagen vascular disease-induced coronary arteritis, substance abuse (cocaine, glue sniffing), trauma, complications of congenital heart disease surgery, genetic disorders (such as progeria), coronary artery embolism, occult malignancy and several other rare conditions. Nephrotic syndrome is a very rare cause of myocardial infarction, but it is probably underestimated. The purpose of this review was to determine the current state of knowledge on acute coronary syndrome related to nephrotic syndrome. We thus performed a comprehensive structured literature search of the Medline database for articles published between January 1st, 1969 and December 31st, 2021. Myocardial infarction in young adults can be broadly divided into two groups: cases of angiographically normal coronary arteries; and cases of coronary artery disease of varying aetiology. There are several possible mechanisms underlying the association between acute coronary syndrome and nephrotic syndrome: (1) coronary thrombosis related to hypercoagulability and/or platelet hyperactivity; (2) atherosclerosis related to hyperlipidaemia; and (3) drug treatment. All of these mechanisms must be evaluated systematically in the acute phase of disease because they evolve rapidly with the treatment of nephrotic syndrome. In this review, we propose a decision algorithm for the management of acute coronary syndrome in the context of nephrotic syndrome. The final part of the review presents the short- and medium-term therapeutic strategies available. Thromboembolism related to nephrotic syndrome is a rare non-atherosclerotic cause of acute coronary syndrome, and prospective studies are needed to evaluate a systematic approach with personalized therapeutic strategies.

Cardiac screening before returning to elite sport after SARS-CoV-2 infection.

BACKGROUND: SARS-CoV-2 infection can induce cardiac damage. Therefore, in the absence of clear data, a cardiac evaluation was recommended for athletes before returning to play after recent SARS-CoV-2 infection. AIM: To assess the proportion of anomalies detected by this cardiac screening. METHODS: We reviewed the medical files of elite athletes referred for cardiac evaluation before returning to play after a non-hospitalized SARS-CoV-2 infection (based on a positive polymerase chain reaction or antigen test) from March 2020 to July 2021 in 12 French centres. RESULTS: A total of 554 elite athletes (professional or national level) were included (median age 22 years, 72.0% male). An electrocardiogram (ECG), echocardiogram and exercise test were performed in 551 (99.5%), 497 (89.7%) and 293 (52.9%) athletes, respectively. We found anomalies with a potential link with SARS-CoV-2 infection in four ECGs (0.7%), three echocardiograms (0.6%) and three exercise tests (1.0%). Cardiac magnetic resonance imaging was performed in 34 athletes (6.1%), mostly due to abnormal first-line examinations, and was abnormal in one (2.9%). The rates of those abnormalities were not higher among athletes with cardiac symptoms or more severe forms of non-hospitalized SARS-CoV-2 infection. Only one athlete had a possible SARS-CoV-2 myocarditis and sport was temporally contraindicated. None had a major cardiac event declared during the follow-up. CONCLUSION: The proportion of cardiac involvement after non-hospitalized forms of SARS-CoV-2 infection in athletes are very low. Systematic cardiac screening before returning to play seems to be unnecessary.

High lipoprotein(a) levels predict severity of coronary artery disease in patients hospitalized for acute myocardial infarction. Data from the French RICO survey.

BACKGROUND: Lipoprotein(a) (Lp(a)) is a well-recognized independent risk factor for atherosclerotic cardiovascular disease (ASCVD). However, limited data are available on the relationship between coronary artery disease (CAD) burden and Lp(a) levels in patients with acute myocardial infarction (MI). OBJECTIVE: The objective of this study was to assess the severity of CAD according to Lp(a) levels from a French regional registry of acute MI. METHODS: CAD burden was assessed in 1213 consecutive patients hospitalized for acute MI in 2019-2020 who underwent coronary angiography. Patients were compared according to their Lp(a) levels: <50 mg/dL (normal), ≥50 mg/dL and ≤100 mg/dL (high) and >100 mg/dL (very high). RESULTS: The prevalence of high and very high Lp(a) was 13% and 6%, respectively. Median age, and rates of diabetes and smoking were similar in all groups. Patients with high or very high Lp(a) were more often under statin therapy, their corrected LDL-cholesterol levels were lower and previous ASCVD rates higher. When compared with lower levels, patients with very high Lp(a) levels had more elevated SYNTAX scores and more frequent multivessel disease. By multivariate logistic regression analysis, the odd ratio for the estimate of multivessel disease was the highest for patients with Lp(a) >100 mg/dL. Moreover, there was a gradual increase in the number of in-hospital deaths across the three Lp(a) groups (p=0.028). CONCLUSIONS: In real-world patients hospitalized for acute MI in France, very high Lp(a) levels are independently associated with a severe CAD burden, supporting the need for systematic screening of Lp(a) in these patients.

Preexisting atrial fibrillation and myocardial infarction: only 10% of infarcts directly linked to atrial fibrillation.

The aim of the study was to evaluate the incidence and prognosis of type 1 myocardial infarction (T1MI) and type 2 MI (T2MI) in patients with acute MI and known atrial fibrillation (AF) to identify MI directly linked to AF. Among the 669 patients, four patients with hyperthyroidism were excluded, and among the remaining 665 patients, about two-thirds were diagnosed with T1MI, and the remaining third were diagnosed with T2MI. AF was the direct cause of MI in 9.8% of our overall population [1.8% of T1MI type C (coronary embolism), 4.9% of T2MI type A and 3.1% of T2MI type B]. Among patients with T2MI, 30-day mortality was lower when the trigger was AF than for the other triggers, for both type 2A (6% vs. 11%) and type 2B (0% vs. 13%). Most cases of AF-related MI are, thus, T2MI, for which therapeutic guidelines are lacking. Given the diverse triggers in T2MI, a specific approach using etiological patterns is needed to properly determine the optimal therapeutic.

Coronary artery embolism and acute coronary syndrome: A critical appraisal of existing data.

The occurrence of coronary artery embolism (CE) has been associated with various clinical conditions, including aortic and mitral prosthetic heart valve implantation, atrial fibrillation (AF), dilated cardiomyopathy, neoplasia, infective endocarditis, atrial septal defect, cardiac tumors, and hypercoagulable states. CE is also a rare cause of myocardial infarction (MI), with a prevalence of about 5%, a figure probably underestimated. The purpose of this article was to determine the current state of knowledge on acute coronary syndrome (ACS) related to CE. We thus performed a comprehensive structured literature search of the MEDLINE database for articles published between 1 January 1990 and 31 December 2021. The diagnosis of CE remains difficult despite the currently used Shibata classification, which is based on major criteria, including angiographic characteristics: globular filling defects, saddle thrombi or multiple filling defects and absence of atherosclerosis in the coronary arteries. Suspected or confirmed CE requires the identification of an etiology. There are only two published series on CE, including about 50 cases each. The three main causes in these series were: 1) atrial fibrillation (73% vs 28.3%), 2) cardiomyopathy (9.4% vs 25%) and 3) malignancy (9.6% vs 15.1%). Finally, 26.3% of the MI patients with CE had no identifiable cause of CE. When anatomically possible, analyzing the thrombus after thrombectomy may help. MI due to CE requires systematic assessment of other locations, i.e. multiple coronary and extracardiac locations. Simultaneous systemic embolization to the brain (67%), limbs (25%), kidneys (25%) or spleen (4%) is frequent, occurring in approximately 25% of CE-related MI. In the setting of acute MI, CE is associated with significant morbidity and mortality. Coronary artery thromboembolism is a rare, non-atherosclerotic, cause of ACS, and prospective studies are needed to evaluate a systematic diagnostic approach and personalized therapeutic strategies.

Cardiovascular Risk Among Patients Who Smoke: Risk Profiles and Differences by Sex.

INTRODUCTION: Smoking is particularly harmful to the cardiovascular system, and smoking-cessation is a key target for cardiovascular prevention. From a large nationwide database on subjects who visited smoking-cessation services, this study assessed the profile and abstinence rate comparing female with male smokers at high cardiovascular risk. METHODS: This was an observational study from the French smoking-cessation services cohort (French national cohort Consultations de Dépendance Tabagique) between 2001 and 2018. Inclusion criteria were being aged ≥18 years and having ≥1 cardiovascular risk factor. Abstinence was self-reported (stopping cigarettes or other tobacco products use ≥28 consecutive days) and confirmed by exhaled carbon monoxide <10 parts per million. Analysis was conducted in 2021. RESULTS: Among 36,864 people who smoke, 15,407 (42%) were women. Women were 3 years younger (48 vs 51 years, p<0.001) and more educated (≥high school diploma: 54% vs 45%, p<0.001) than men. The burden of cardiovascular risk factors was slightly lower in women than in men and, for hypercholesterolemia, hypertension, diabetes, and cardiovascular diseases, were half as frequent in women as they were in men (16% vs 32%, p<0.001). However, women suffered more often from obesity, respiratory diseases, and anxiety‒depression symptoms (53% vs 39%, p<0.001). Finally, although women were less nicotine dependent, their abstinence rate was slightly lower (52.6% vs 55.2%, p<0.001). CONCLUSIONS: Women who smoked had a high burden of risk factors, especially obesity and elevated rates of lung diseases, and a lower abstinence rate, with more common anxiety‒depression symptoms. Men who smoked had a higher prevalence of cardiovascular disease, higher nicotine dependence, and coaddictions. These findings highlight the need to strengthen cardiovascular prevention strategies through comprehensive sex-tailored smoking-cessation interventions.

Mid-Term Mortality in Older Anemic Patients with Type 2 Myocardial Infarction: Does Blood Transfusion sImprove Prognosis?

(1) Anemia often predisposes older patients to type 2 myocardial infarction (T2MI). However, the management of this frequent association remains uncertain. We aimed to evaluate the impact of red blood cell transfusion during the acute phase of T2MI in older anemic inpatients. (2) Methods and results: We performed a retrospective study using a French regional database. One hundred and seventy-eight patients aged 65 years or older, presenting with a T2MI and anemia, were selected. Patients were split into two groups: one that received a red blood cell transfusion (≥1 red blood cell unit) and one that did not. A propensity score was built to adjust for potential confounders, and the association between transfusion and 30-day mortality was evaluated with an inverse propensity score weighted Cox model. Transfusion was not associated with 30-day all-cause mortality (propensity score weighted hazard ratio (HR) 1.59 (0.55-4.56), p = 0.38). However, 1-year all-cause mortality was significantly higher in the transfusion group (propensity score weighted HR 2.47 (1.22-4.97), p = 0.011). (3) Conclusion: Our findings in older adults with anemia suggest that blood transfusion in the acute phase of T2MI could not be associated with improved short-term prognosis. Prospective studies are urgently needed to assess the impact of transfusion on longer-term prognosis.

Smoking in Patients With Chronic Cardiovascular Disease During COVID-19 Lockdown.

Objectives: This cross-sectional study aims to investigate health-related behaviors including tobacco consumption among patients with cardiovascular diseases (CVD), during the first COVID-19-related lockdown. Methods: After 5 weeks of COVID-19 lockdown, 220 patients with chronic coronary syndromes (CCS) and 124 with congestive heart failure (CHF) answered a phone questionnaire. Results: Among these 344 patients, 43 (12.5%) were current smokers, and none had quit during the lockdown. When compared with non-smokers, smokers were 15 years younger, more often diabetic, more likely to live in an urban than a rural lockdown location, and more often in the CCS cohort (p = 0.011). Smokers described greater psychological impairment, but their rates of decrease in physical activity and of increase in screen time were similar to non-smokers. More than one-third (13/43) increased their tobacco consumption, which was mainly related to stress or boredom, but not driven by media messages on a protective effect of nicotine. Conclusions: During the first COVID-19 lockdown, we found a decrease in favorable lifestyle behaviors among patients with CVD. Strikingly, one-third of smokers with CCS or CHF increased their tobacco consumption. Given the major impact of persistent smoking in patients with CVD, this highlights the need for targeted prevention strategies, in particular during such periods.

New horizons in Type 2 myocardial infarction: pathogenesis, assessment and management of an emerging geriatric disease.

Type 2 myocardial infarction (MI) is characterised by a functional imbalance between myocardial oxygen supply and demand in the absence of a thrombotic process, leading to myocardial necrosis. This type of MI was relatively unknown among clinicians until the third universal definition of MI was published in 2017, differentiating Type 2 from Type 1 MI, which follows an acute atherothrombotic event. The pathogenesis, diagnostic and therapeutic aspects of Type 2 MI are described in the present review. Type 2 MI is a condition that is strongly linked to age because of vascular ageing concerning both epicardic vessels and microcirculation, age-related atherosclerosis and stress maladaptation. This condition predominantly affects multimorbid individuals with a history of cardiovascular disease. However, the conditions that lead to the functional imbalance between oxygen supply and demand are frequently extra-cardiac (e.g. pneumonia or anaemia). The great heterogeneity of the underlying etiological factors requires a comprehensive approach that is tailored to each case. In the absence of evidence for the benefit of invasive reperfusion strategies, the treatment of Type 2 MI remains to date essentially based on the restoration of the balance between oxygen supply and demand. For older co-morbid patients with Type 2 MI, geriatricians and cardiologists need to work together to optimise etiological investigations, treatment and prevention of predisposing conditions and precipitating factors.

COVID-19 Lockdown in Patients with Chronic Diseases: A Cross-Sectional Study.

Background: We aimed to investigate the impact of the first COVID-19 lockdown on medication adherence, physician access, lifestyle behaviours, and mental health in patients with chronic conditions. Methods: A cross-sectional phone survey was conducted in 1274 housebound adults recruited from 8 regional chronic disease cohorts (CLEO CD study: NCT04390126). Results: Medication adherence was 97%; 305 (41%) patients declared that at least one scheduled visit with a physician was missed during the first lockdown. The main changes in lifestyle behaviours were deterioration in sleep time (duration and/or quality; 71%), increase in screen time (46%), and decrease in physical activity (46%). Nineteen percent experienced psychological distress (Kessler-6 score ≥ 5). An urban living place (OR, 1.76 vs. rural; 95% CI, 1.32−2.33; p = 10−4), worse self-reported mental health (OR, 1.62 vs. about the same or better; 95% CI, 1.17−2.25; p = 0.003), and a K6 score ≥ 5 (OR, 1.52 vs. <5; 95% CI, 1.05−2.21; p = 0.03) were independent factors associated with at least one unhealthy behaviour. Conclusions: Encouraging results were observed in terms of medication adherence. Caution is needed in chronic disease patients living in urban places as well as those presenting psychological distress and worse self-reported mental health to reduce unhealthy behaviours.

Environmental noise exposure is associated with atherothrombotic risk.

There is growing evidence that environmental noise exposure could increase the risk of atherothrombotic events, including acute myocardial infarction (MI). We analysed the burden of environmental noise on atherothrombotic risk in MI patients. From the RICO survey, 879 consecutive MI patients included from 2004 to 2008 and living in an urban unit of > 237,000 inhabitants were analysed. Atherothrombotic risk was calculated using the TRS-2P score. TRS-2P categories were split into low (TRS-2P = 0/1) (40.8%), medium-low (TRS-2P = 2) (25.7%), medium-high (TRS-2P = 3) (21.8%) and high risk (TRS-2P ≥ 4) (11.6%). Noise exposure was associated with atherothrombotic risk, with the LAeq,24 h (OR (95% CI): 1.165 (1.026-1.324)) and Lnight (OR (95CI): 1.157 (1.031-1.298)), for each 10 dB(A) increase. After adjustment, noise exposure remained a predictor of atherothrombotic risk, with LAeq,24 h (OR (95% CI): 1.162 (1.011-1.337)) and with Lnight (OR (95% CI): 1.159 (1.019-1.317)). The relationship with transportation Lnight was significant for men (OR (95% CI): 1.260 (1.078-1.472)) but not for women (OR (95% CI): 0.959 (0.763-1.205)). We found a significant association between residential traffic noise exposure and atherothrombotic risk in men but not in women. These results could have major consequences for secondary prevention.

Tobacco-related cardiovascular risk in women: New issues and therapeutic perspectives.

BACKGROUND: Smoking is the main modifiable risk factor for stroke and myocardial infarction, particularly in women; its prevalence in France is evolving, and new patterns of nicotine consumption have emerged. AIMS: To present contemporary data on smoking prevalence and the use of electronic cigarettes, and to describe current knowledge of the cardiovascular risk specificities and the effectiveness of withdrawal methods in women. METHOD: We identified studies by searching the MEDLINE bibliographic database between 1995 and 2020, and the Weekly Epidemiological Bulletin (Bulletin Épidémiologique Hebdomadaire) published by the French health authorities. RESULT: In recent years, smoking prevalence among French women has decreased overall, except in the oldest age group (aged>55 years). At the same time, the incidence of hospitalization for cardiovascular events has increased worryingly among women smokers aged<65 years. Active smoking in women is associated with an increased risk of premature myocardial infarction, and a risk of stroke that increases with the number of cigarettes consumed per day; it is also responsible for increased cardiovascular events in women taking oestrogen-progestin contraception. Quitting smoking reverses these effects in the long term, and women are just as likely to quit smoking as men. CONCLUSIONS: Stopping smoking must be a priority objective for women smokers, for primary and secondary prevention, and they should systematically be offered a validated method of cessation or even electronic cigarettes.

Smoking and Vaping in Amateur Rugby Players, Coaches and Referees: Findings from a Regional Survey Might Help to Define Prevention Targets.

A high prevalence of cigarette smoking has been documented in France, and new patterns of tobacco and nicotine consumption are emerging, especially in some sports. In the amateur rugby population, data are scarce on harmful consumption and on the awareness of the risk of smoking. We analyzed the consumption of tobacco and other nicotine products in French amateur players, coaches and referees. Amateur players (>12 years old), coaches and referees participating in the Burgundy amateur championship were invited to answer an electronic, anonymous questionnaire during the 2017-2018 sport season. Among the 683 subjects (gender ratio M/F = 0.9), 176 (25.8%) were current smokers, including 32.4% of the referees and 28.2% of the coaches. The prevalence of smokers was higher in females (37.5%) than in males (24.6%). Most (86.4%) smoked within 2 h before/after a rugby session. Only 28 subjects (4.1%) usually vaped; 21 of them (75%) vaped within 2 h before/after a rugby session. Other tobacco or nicotine products were infrequent. The awareness about the risks of smoking before/after sport was incomplete, including in coaches and referees. The prevalence of cigarette smoking is alarming across the whole spectrum of rugby amateur actors. Education programs are urgently needed to reduce tobacco consumption in this at-risk population.

Coronary lesion complexity in patients with heterozygous familial hypercholesterolemia hospitalized for acute myocardial infarction: data from the RICO survey.

BACKGROUND: Although patients with familial heterozygous hypercholesterolemia (FH) have a high risk of early myocardial infarction (MI), the coronary artery disease (CAD) burden in FH patients with acute MI remains to be investigated. METHODS: The data for all consecutive patients hospitalized in 2012-2019 for an acute MI and who underwent coronary angiography were collected from a multicenter database (RICO database). FH (n = 120) was diagnosed using Dutch Lipid Clinic Network criteria (score ≥ 6). We compared the angiographic features of MI patients with and without FH (score 0-2) (n = 234) after matching for age, sex, and diabetes (1:2). RESULTS: Although LDL-cholesterol was high (208 [174-239] mg/dl), less than half of FH patients had chronic statin treatment. When compared with non-FH patients, FH increased the extent of CAD (as assessed by SYNTAX score; P = 0.005), and was associated with more frequent multivessel disease (P = 0.004), multiple complex lesions (P = 0.022) and significant stenosis location on left circumflex and right coronary arteries. Moreover, FH patients had more multiple lesions, with an increased rate of bifurcation lesions or calcifications (P = 0.021 and P = 0.036, respectively). In multivariate analysis, LDL-cholesterol levels (OR 1.948; 95% CI 1.090-3.480, P = 0.024) remained an independent estimator of anatomical complexity of coronary lesions, in addition to age (OR 1.035; 95% CI 1.014-1.057, P = 0.001). CONCLUSIONS: FH patients with acute MI had more severe CAD, characterized by complex anatomical features that are mainly dependent on the LDL-cholesterol burden. Our findings reinforce the need for more aggressive preventive strategies in these high-risk patients, and for intensive lipid-lowering therapy as secondary prevention.
