RESUMO

Introduction: Evidence regarding the impact of prophylactic implantation of venoarterial extracorporeal membrane oxygenation (VA-ECMO) for elective high-risk percutaneous coronary intervention (PCI) is limited. The purpose of this paper is to evaluate the outcome during index hospitalization and 3 years after interventions. Methods: This is an observational retrospective study including all patients undergoing elective, high-risk PCI and receiving VA-ECMO for cardiopulmonary support. Primary endpoints were in-hospital and 3- year major adverse cardiovascular and cerebrovascular event (MACCE) rates. Secondary endpoints were vascular complications, bleeding, and procedural success. Results: Nine patients were included in total. All patients were considered inoperable by the local heart team, and 1 patient had a previous coronary artery bypass graft (CABG). All patients were hospitalized for an acute heart failure episode 30 days before the index procedure. Severe left ventricular dysfunction was present in 8 patients. The main target vessel was the left main coronary artery in 5 cases. Complex PCI techniques were used: bifurcations with 2 stents in 8 patients, rotational atherectomy was performed in 3, and coronary lithoplasty in 1 case. PCI was successful in all of the patients with revascularization of all target and additional lesions. Eight of the 9 patients survived for at least 30 days after the procedure, and 7 patients survived for 3 years after the procedure. Regarding the complication rate, 2 patients suffered from limb ischemia and were treated by an antegrade perfusion, 1 patient had a femoral perforation that needed surgical repair, 6 patients had a hematoma, 5 patients had a significant drop in hemoglobin of more than 2 g/dl and received blood transfusions, 2 patients were treated for septicemia, and 2 patients needed hemodialysis. Conclusions: Prophylactic use of VA-ECMO in elective patients is an acceptable strategy for revascularization by high-risk coronary percutaneous interventions with good long-term outcomes for patients considered inoperable when a clear clinical benefit is expected. Regarding the potential risk of complications due to a VA-ECMO system, the selection of candidates in our series was based on a multiparameter analysis. The two main triggers in favor of prophylactic VA-ECMO in our studies were the presence of a recent heart failure episode and the high probability of periprocedural prolonged impairment of the coronary flow through the major epicardial artery.

RESUMO

OBJECTIVE: Terminal 6q deletion is a rare genetic condition associated with a neurodevelopmental disorder characterized by intellectual disability and structural brain anomalies. Interestingly, a similar phenotype is observed in patients harboring pathogenic variants in the DLL1 gene. Our study aimed to further characterize the prenatal phenotype of this syndrome as well as to attempt to establish phenotype-genotype correlations. METHOD: We collected ultrasound findings from 22 fetuses diagnosed with a pure 6qter deletion. We reviewed the literature and compared our 22 cases with 14 fetuses previously reported as well as with patients with heterozygous DLL1 pathogenic variants. RESULTS: Brain structural alterations were observed in all fetuses. The most common findings (>70%) were cerebellar hypoplasia, ventriculomegaly, and corpus callosum abnormalities. Gyration abnormalities were observed in 46% of cases. Occasional findings included cerebral heterotopia, aqueductal stenosis, vertebral malformations, dysmorphic features, and kidney abnormalities. CONCLUSION: This is the first series of fetuses diagnosed with pure terminal 6q deletion. Based on our findings, we emphasize the prenatal sonographic anomalies, which may suggest the syndrome. Furthermore, this study highlights the importance of chromosomal microarray analysis to search for submicroscopic deletions of the 6q27 region involving the DLL1 gene in fetuses with these malformations.

RESUMO

According to the literature, tiny amounts of transition metals in airborne fine particles (PM2.5) may induce proinflammatory cell response through reactive oxygen species production. The solubility of particle-bound metals in physiological fluids, i.e. the metal bioaccessibility is driven by factors such as the solution chemical composition, the contact time with the particles, and the solid-to-liquid phase ratio (S/L). In this work, PM2.5-bound metal bioaccessibility was assessed in various physiological-like solutions including cell culture media in order to evidence the potential impact on normal human bronchial epithelial cells (NHBE) when studying the cytotoxicity and inflammatory responses of PM2.5 towards the target bronchial compartment. Different fluids (H2O, PBS, LHC-9 culture medium, Gamble and human respiratory mucus collected from COPD patients), various S/L conditions (from 1/6000 to 1/100,000) and exposure times (6, 24 and 72h) were tested on urban PM2.5 samples. In addition, metals' total, soluble and insoluble fractions from PM2.5 in LHC-9 were deposited on NHBE cells (BEAS-2B) to measure their cytotoxicity and inflammatory potential (i.e., G6PDH activity, secretion of IL-6 and IL-8). The bioaccessibility is solution-dependent. A higher salinity or organic content may increase or inhibit the bioaccessibiliy according to the element, as observed in the complex mucus matrix. Decreasing the S/L ratio also affect the bioaccessibility depending on the solution tested while the exposure time appears less critical. The LHC-9 culture medium appears to be a good physiological proxy as it induces metal bioaccessibilities close to the mucus values and is little affected by S/L ratios or exposure time. Only the insoluble fraction can be linked to the PM2.5-induced cytotoxicity. By contrast, both soluble and insoluble fractions can be related to the secretion of cytokines. The metal bioaccessibility in LHC-9 of the total, soluble, and insoluble fractions of the PM2.5 under study did not explain alone, the cytotoxicity nor the inflammatory response observed in BEAS-2B cells. These findings confirm the urgent need to perform further toxicological studies to better evaluate the synergistic effect of both bioaccessible particle-bound metals and organic species.

RESUMO

OBJECTIVE: To develop a new predictive model of maximal heart rate based on two walking tests at different speeds (comfortable and brisk walking) as an alternative to a cardiopulmonary exercise test during cardiac rehabilitation. DESIGN: Evaluation of a clinical assessment tool. SETTING: A Cardiac Rehabilitation Department in France. SUBJECTS: A total of 148 patients (133 men), mean age of 59 ±9 years, at the end of an outpatient cardiac rehabilitation programme. MAIN MEASURES: Patients successively performed a 6-minute walk test, a 200 m fast-walk test (200mFWT), and a cardiopulmonary exercise test, with measure of heart rate at the end of each test. An all-possible regression procedure was used to determine the best predictive regression models of maximal heart rate. The best model was compared with the Fox equation in term of predictive error of maximal heart rate using the paired t-test. RESULTS: Results of the two walking tests correlated significantly with maximal heart rate determined during the cardiopulmonary exercise test, whereas anthropometric parameters and resting heart rate did not. The simplified predictive model with the most acceptable mean error was: maximal heart rate = 130 - 0.6 × age + 0.3 × HR200mFWT (R(2) = 0.24). This model was superior to the Fox formula (R(2) = 0.138). The relationship between training target heart rate calculated from measured reserve heart rate and that established using this predictive model was statistically significant (r = 0.528, p < 10(-6)). CONCLUSIONS: A formula combining heart rate measured during a safe simple fast walk test and age is more efficient than an equation only including age to predict maximal heart rate and training target heart rate.

RESUMO

OBJECTIVES: The French government voted a new law in February 2016 called the Claeys-Leonetti Law, which established the right to deep and continuous sedation, confirmed the ban on euthanasia and ruled out physician-assisted suicide. The aim of this work was to gather the opinion of patients on continuous sedation and the legalisation of medical assistance in dying and to explore determinants associated with favourable and unfavourable opinions. METHODS: This was a French national prospective multicentre study between 2016 and 2020. RESULTS: 331 patients with incurable cancer suffering from locally advanced or metastatic cancer in 14 palliative care units were interviewed. 48.6% of participants expressed a favourable opinion about physician-assisted suicide and 27.2% an unfavourable opinion about its legalisation. Regarding euthanasia, 52% of patients were in favour of its legalisation. In univariate analysis, the only factor determining opinion was belief in God. CONCLUSIONS: While most healthy French people are in favour of legalising euthanasia, only half of palliative care patients expressed this opinion. Medical palliative care specialists were largely opposed to euthanasia. The only determining factor identified was a cultural factor that was independent of the other studied variables. This common factor was found in other studies conducted on cohorts from other countries. This study contributes to the knowledge and thinking about the impact of patients' personal beliefs and values regarding their opinions about euthanasia and assisted suicide. TRIAL REGISTRATION NUMBER: NCT03664856.

RESUMO

OBJECTIVE: The objective of the study was to evaluate the use of 17 alpha-hydroxyprogesterone caproate (17P) to reduce preterm delivery in women with a twin pregnancy and short cervix. STUDY DESIGN: This open-label, multicenter, randomized controlled trial included women with a twin pregnancy between 24(+0) and 31(+6) weeks of gestation who were asymptomatic and had a cervical length of 25 mm or less measured by routine transvaginal ultrasound. Women were randomized to receive (or not) 500 mg of intramuscular 17P, repeated twice weekly until 36 weeks or preterm delivery. The primary outcome was time from randomization to delivery. Analysis was performed according to the intent-to-treat principle. RESULTS: The 17P and control groups did not differ significantly for median [interquartile range] time to delivery: 45 (26-62) and 51 (36-66) days, respectively. However, treatment with 17P was associated with a significant increase in the rate of preterm delivery before 32 weeks. CONCLUSION: Twice-weekly injections of 17P did not prolong pregnancy significantly in asymptomatic women with a twin pregnancy and short cervix.

RESUMO

BACKGROUND AND AIM: Periodontal disease, including bone loss, is thought to be involved in coronary artery disease. Multiple complex coronary lesions relate to multifocal destabilization of coronary plaques. We investigated whether bone loss could be associated with the presence of multiple complex coronary lesions. METHODS: This cross-sectional study included 150 patients with recent myocardial infarction (<1 month). Multiple complex coronary lesions were determined at coronary angiography. A panoramic dental X-ray including bone loss >50% was performed. Patients with no or simple complex lesions were compared to patients with multiple complex lesions. RESULTS: Over 20% of patients had multiple complex coronary lesions. Patients with multiple complex lesion were less likely to be women and more likely to have multivessel disease or elevated C-reactive protein (CRP) than patients with no or single complex lesion. Bone loss >50% tended to be more frequent in patients with multiple complex lesions (p = 0.063). In multivariate analysis, multivessel disease, gender and CRP were associated with multiple complex lesion. Bone loss >50% increased the risk of multiple complex lesion. CONCLUSION: Bone loss was associated with complex multiple coronary lesions, beyond systemic inflammation. These findings may bear important clinical implications for the prevention and treatment of coronary artery disease.

RESUMO

This study aimed to evaluate the perception and long-term effects of an educative consultation performed before cardiac rehabilitation discharge. The patient and the referring nurse summed up the educative interventions, and filled a personalized form summarizing tertiary prevention goals. Fifty patients were contacted by mail at 11 ± 1 months, and called at 4.2 ± 0.2 years after discharge, to evaluate their satisfaction and assess cardiovascular risk factors (CVRF) control. Mail response rate was 82%, and 90% of patients believed that it had encouraged them to adopt a healthier lifestyle. Almost half the number of patients declared that they considered the nurse intervention as positive. Telephone response rate was 54%. Most long-term effects were better than usually reported in the field of multidisciplinary secondary prevention of CVRF. Patients felt that this educational action was positive, even though highlighting this role of nurses seems necessary. Additional controlled trials are needed to provide rigorous validation of this strategy.

RESUMO

OBJECTIVE: To estimate the minimal clinically important difference (MCID) for the 6-minute walk test (6MWT) and the 200-m fast-walk test (FWT) in patients with coronary artery disease (CAD) during a cardiac rehabilitation program. DESIGN: Prospective study using distribution- and anchor-based methods. SETTING: Outpatients from a cardiac rehabilitation unit. PARTICIPANTS: Stable patients with CAD (N=81; 77 men; mean±SD age, 58.1±8.7y) enrolled 31±12.1 days after an acute coronary syndrome (ACS). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: 6MWT and 200-m FWT results before and after an 8-week cardiac rehabilitation program and at the 6th and 12th sessions. Patients and physiotherapists who supervised the training were asked to provide a global rating of perceived change in walking ability while blinded to changes in walk test performances. RESULTS: Mean change in 6MWT distance (6MWD) in patients who reported no change was -6.5m versus 23.3m in those who believed their performance had improved (P<.001). This result was consistent with the MCID determined by using the distribution method (23m). Considering a 25-m cutoff, positive and negative predictive values were 0.9 and .63, respectively. Conversely, there was no difference in 200-m FWT performance between these 2 groups (0.1 vs -1.4s, respectively). There was poor agreement with the physiotherapist's perceived change. CONCLUSIONS: The MCID for 6MWD in patients with CAD after ACS was 25m. This result will help physicians interpret 6MWD change and help researchers estimate sample sizes in further studies using 6MWD as an endpoint.

RESUMO

Bats undertaking seasonal migration between summer roosts and wintering areas can cross large areas of open sea. Given the known impact of onshore wind turbines on bats, concerns were raised on whether offshore wind farms pose risks to bats. Better comprehension of the phenology and weather conditions of offshore bat migration are considered as research priorities for bat conservation and provide a scientific basis for mitigating the impact of offshore wind turbines on bats. This study investigated the weather conditions linked to the migratory activity of Pipistrellus bats at multiple near- and offshore locations in the Belgian part of the North Sea. We found a positive relationship between migratory activity and ambient temperature and atmospheric pressure and a negative relationship with wind speed. The activity was highest with a wind direction between NE and SE, which may favor offshore migration towards the UK. Further, we found a clear negative relationship between the number of detections and the distance from the coast. At the nearshore survey location, the number of detections was up to 24 times higher compared to the offshore locations. Our results can support mitigation strategies to reduce offshore wind farm effects on bats and offer guidance in the siting process of new offshore wind farms.

RESUMO

OBJECTIVES: Venovenous extracorporeal membrane oxygenation has been largely used in patients with refractory acute respiratory distress syndrome due to coronavirus disease 2019. Few data on long-term pulmonary function among venovenous extracorporeal membrane oxygenation survivors are available. DESIGN: Retrospective, observational cohort. SETTING: Two mixed medical-surgical tertiary (30 beds) and secondary (22 beds) ICUs. PATIENTS: All critically ill adult coronavirus disease 2019 survivors treated with venovenous extracorporeal membrane oxygenation between March 10, and April 30, 2020. MEASUREMENTS AND MAIN RESULTS: The last available lung function and 6-minute walking tests, performed after a median of 178 days (ranges, 72-232 d) from ICU admission, were analyzed. Among the 32 coronavirus disease 2019 patients treated by venovenous extracorporeal membrane oxygenation during the study period, 11 (34%; median age 56 yr; median duration of mechanical ventilation and extracorporeal membrane oxygenation therapy of 26 and 15 d, respectively) were successfully weaned and discharged home. Spirometry was performed in nine patients; the volumetric lung function was preserved, that is, median forced vital capacity was 83% of predicted value (51-99% of predicted value), and median forced expiratory volume in 1 second was 82% of predicted value (60-99% of predicted value). Also, the median residual volume and the lung capacity were 100% of predicted value (50-140% of predicted value) and 90% of predicted value (50-100% of predicted value); only the diffusion capacity of the lung for carbon monoxide and 6-minute walking test were decreased (58% of predicted value [37-95% of predicted value] and 468 meters (365-625 meters), corresponding to [63-90% of predicted value], respectively). CONCLUSIONS: Among survivors from severe coronavirus disease 2019 pneumonia treated with venovenous extracorporeal membrane oxygenation, preserved long-term volumetric lung function with decreased diffusion capacity of lung carbon monoxide was observed.

RESUMO

BACKGROUND: An elevated body mass index (BMI) has been reported to be associated with a lower rate of death after acute myocardial infarction (AMI). However, waist circumference (WC) may be a better marker of cardiovascular risk than BMI. We used data from a contemporary French population-based cohort of patients with AMI to analyze the impact of WC and BMI on death rates. METHODS AND RESULTS: We evaluated 2229 consecutive patients with AMI. Patients were classified according to BMI as normal, overweight, obese, and very obese (BMI <25, 25 to 29.9, 30 to 34.5, and >35 kg/m(2), respectively) and as increased waistline (WC >88/102 cm for women/men) or normal. Half of the patients were overweight (n=1044), and one quarter were obese (n=397) or very obese (n=128). Increased WC was present in half of the patients (n=1110). Increased BMI was associated with a reduced death rate, with a 5% risk reduction for each unit increase in BMI (hazard ratio, 0.95; 95% CI, 0.93 to 0.98; P<0.001). In contrast, WC as a continuous variable had no impact on all-cause death (P=0.20). After adjustment for baseline predictors of death, BMI was not independently predictive of death. The group of patients with high WC but low BMI had increased 1-year death rate. CONCLUSIONS: Neither BMI nor WC independently predicts death after AMI. Much of the inverse relationship between BMI and the rate of death after AMI is due to confounding by characteristics associated with survival. This study emphasizes the need to measure both BMI and WC because patients with a high WC and low BMI are at high risk of death.

RESUMO

BACKGROUND AND AIM: We aimed to investigate cardiovascular risk factors and health behaviours prospectively in a large population of French amateur rugby players. METHODS: An anonymous questionnaire was displayed to rugby players aged over 12 years enrolled in the 2014-2015 French amateur rugby championship from the Burgundy region (n = 5140). Questions addressed awareness on: (a) cardiovascular prevention; (b) tobacco, alcohol and highly caffeinated beverages consumption; and (c) adherence to prevention guidelines (ECG checks, training in basic life support, avoidance of sports practice during fever/infectious episodes). RESULTS: Among the 640 participants who completed the questionnaires, most were male (90%) and were aged under 35 years (80%). Almost half had basic life support training (42%), but only a minority attended an ECG check-up before licensing (37%), and only a few were aware of the cardiovascular prevention information campaign (17%), similarly across the age groups. Surprisingly, playing rugby with fever was commonly reported (44%) and was even more frequent in young women (55%). A high number of respondents were current smokers (35%), of whom most reported consumption less than 2 hours before/after a rugby session. Alcohol drinkers were frequent (69%), of whom most (79%) drank alcohol less than 2 hours before/after a match. Highly caffeinated beverages consumption (34%) was high, particularly in younger players (39%). Half highly caffeinated beverages consumption was in the setting of a rugby session, even greater in women and mainly motivated by performance enhancement (34%). CONCLUSION: Our findings from a representative regional cohort may help to identify targets for cardiovascular prevention through the development of educational programmes aiming to improve the knowledge and behaviour of amateur rugby players.

RESUMO

OBJECTIVES: The goal of the present study was to test the impact of ST segment resolution (STR) after rescue percutaneous coronary intervention (PCI) on the short-term prognosis. BACKGROUND: The prognostic value of STR after rescue PCI for acute ST elevation myocardial infarction (STEMI) remains undetermined. METHODS: From the French regional database, we analyzed 168 consecutive patients with STEMI and failed lysis, defined by <50 percent STR, who underwent rescue PCI. Patients were classified into two groups according to the degree of STR from the maximal ST-elevation measured on the single worst ECG lead before lysis and after rescue PCI: the without STR group (<50% STR) vs. the with STR group (> or =50%). RESULTS: After rescue PCI, 26 (15%) patients did not have STR and 142 (85%) patients did. No difference was observed between the two groups regarding baseline characteristics, risk factors, and median time delay either from symptom onset to thrombolysis or from failed lysis to rescue PCI. We observed a lower proportion of patients with TIMI 2/3 flow post PCI in the without STR group (respectively 61% vs. 97%, P < 0.001) but an increased use of intra-aortic balloon counterpulsation (34% vs. 8%, P < 0.001) in this group. Thirty-day mortality was markedly higher in the without STR group than in the with STR group (27% vs. 9% respectively, P = 0.025). Moreover, multivariate analysis showed that absence of STR (OR: 5.65; 95% CI: 1.24-25.67), was an independent prognostic factor for mortality. CONCLUSIONS: We showed for the first time that analysis of ST-segment resolution may be a simple reliable tool to identify patients at high risk after rescue PCI, and may provide useful information for the elaboration of therapeutic strategies.

RESUMO

OBJECTIVE: The prognosis of patients with acute myocardial infarction (MI), according to the new criteria for impaired fasting glucose (IFG) (FG 100-126 mg/dl), has not been evaluated. RESEARCH DESIGN AND METHODS: A total of 2353 patients with acute MI and surviving at d 5 after admission were analyzed for short-term morbidity and mortality. FG was obtained at d 4 and 5. Patients were classified as diabetes mellitus (known diabetes or FG > or = 126 mg/dl), high IFG (110 < or = FG < 126 mg/dl), low IFG (100 < or = FG < 110 mg/dl), and normal fasting glucose (NFG) (FG < 100 mg/dl). RESULTS: Among the 2353 patients, 968 (41%) had diabetes mellitus, 262 (11%) had high IFG, 332 (14%) had low IFG, and 791 (34%) had NFG. Compared with NFG patients, 30-d cardiovascular mortality was increased in high but not low IFG subjects. In-hospital heart failure was increased in high IFG subjects (42 vs. 20% for NFG, P < 0.0001) but not low IFG subjects (21 vs. 20%). High IFG, but not low IFG, was an independent factor associated with 30-d cardiovascular mortality [odds ratio 2.33 (1.55-3.47)] and in-hospital heart failure [odds ratio 1.70 (1.36-2.07)]. The optimal threshold levels of FG on the receiver-operating characteristic curves were 114 and 112 mg/dl to predict mortality and in-hospital heart failure, respectively. CONCLUSION: The present study, based on a nonselected cohort of MI patients, underscores the high prevalence of IFG (25%) and highlights the clinical relevance of 110 mg/dl, but not 100 mg/dl, as a cutoff value to define the risk for worse outcome.

RESUMO

BACKGROUND: We aimed to investigate the determinants and outcomes of multiple complex lesions (MCLs) on coronary angiography in patients with an acute myocardial infarction. METHODS: One thousand one hundred fifty-two consecutive nonselected myocardial infarction patients who underwent coronary angiography within 24 hours after admission were analyzed. A complex lesion was defined by the presence of thrombus, ulceration, irregular plaque, and flow impairment. Patients with < or = 1 complex lesion were considered with single complex lesion (SCL), and patients with > 1 complex lesions with MCLs. RESULTS: Multiple complex lesions were identified in 360 patients (31%). Patients from the MCL group were older and had a higher rate of cardiovascular risk factors but were less likely to be smokers when compared with the SCL group. Patients with MCLs were more likely to have altered left ventricular ejection fraction and multivessel disease and showed a trend toward an increased median time delay to revascularization (360 vs 285 minutes; P = .070). Moreover, the C-reactive protein (CRP) plasma levels increased with the number of CLs. By multivariate analysis, multivessel disease and CRP level were associated with the presence of MCLs. When compared with the SCL group, patients with MCLs had a higher risk of inhospital cardiogenic shock (18% vs 11%; P = .005) and 30-day mortality (11% vs 6%; P = .002). At 1-year follow-up, the presence of MCLs was an independent predictive factor of death. CONCLUSIONS: This study shows that the presence of MCLs is associated with worse outcomes and that risk factors such as CRP are able to identify patients at a high risk for MCLs.

RESUMO

BACKGROUND: Randomized studies have shown a reduction in cardiovascular events associated with low doses of statin among hypertensive patients at only moderate cardiovascular risk. The hypothesis of the present study was that statin therapy initiated during hospitalization could improve the long-term outcome after acute myocardial infarction (MI) in hypertensive patients. METHODS: From the French regional obserRvatoire des Infarctus de Côte d'Or (RICO) survey, 1076 patients with a history of hypertension, surviving acute MI were included. Patients on statin therapy initiated before their hospitalization were excluded from the study. Patients were categorized into two groups based on whether or not statin treatment was initiated during the hospital stay. RESULTS: Patients in the statin group were younger (70 years [range, 58 to 77 years] v 75 years [range, 65 to 82 years], P < .001) and were more likely to have hypercholesterolemia (42% v 28 %, P < .001). No differences were observed between the two groups for LDL-cholesterol levels on admission. At 1-year follow-up, cardiovascular mortality and rehospitalization for heart failure were lower in the statin group (respectively, 5% v 15%, P < .001; 5% v 7%, P < .001). Multivariate analysis showed that statin therapy was associated with decreased mortality (hazard ratio [95% confidence interval; CI]: 0.58 [0.32-0.98], P = .035) independently of either hypercholesterolemia, the use of beta-blockers, angiotensin-converting enzyme inhibitors, or diuretics, but not with a decreased incidence of heart failure (hazard ratio [95% CI]: 0.88 [0.55-1.23], P = .152). CONCLUSIONS: In this observational study, the long-term benefits of statin therapy initiated in-hospital in hypertensive patients after acute MI was demonstrated. These findings may have implications for treatment optimization of hypertensive patients in secondary prevention.

RESUMO

Hyperglycemia has been shown to be a powerful predictor of worse outcome after ST-segment-elevation myocardial infarction (STEMI), which could be related to impaired myocardial reperfusion. This study investigated the association between hyperglycemia and ST-segment resolution (STR) after thrombolysis. From the French regional Observatoire des Infarctus de Côte-d'Or survey, admission glucose in 371 patients with STEMIs who were treated by lysis<12 hours was analyzed. The single worst lead electrocardiogram before and 90 minutes after lysis was analyzed, and patients were divided into 3 groups according to the degree of STR: none (<30%), partial (30% to 70%), or complete (>or=70%). Of the 371 patients, 101 (27.2%) had no STR, 124 (33.4%) had partial STR, and 146 (39.4%) had complete STR. STR decreased with increasing glycemia (p=0.029), and patients with hyperglycemia (glycemia>or=11 mmol/L) were more likely to have no STR. Moreover, hyperglycemia was an independent predictor of incomplete STR even after adjustment for potential confounders (odds ratio 2.348, 95% confidence interval 1.212 to 4.547). In conclusion, the present study suggests a strong association between hyperglycemia and electrocardiographic signs of reperfusion in patients with STEMIs after lysis and suggests the usefulness of evaluating early glycemic control in the setting of reperfusion for acute myocardial infarction.

RESUMO

BACKGROUND: The impact of metabolic syndrome after acute myocardial infarction (AMI) has not yet been studied. In a population-based sample of patients with AMI, we sought to determine the prevalence of metabolic syndrome in patients with AMI, its impact on hospital outcomes, and to assess the relative influence of each of the components of the National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III definition of metabolic syndrome on the risk of death and heart failure. METHODS: A total of 633 unselected, consecutive patients hospitalized with AMI were categorized according to the NCEP ATP III metabolic syndrome criteria (presence of >/=3 of the following: hyperglycemia; triglyceride level >/=150 mg/dL [>/=1.7 mmol/L]; high-density lipoprotein cholesterol level <40 mg/dL [<1.04 mmol/L] in men and <50 mg/dL [<1.30 mmol/L] in women; blood pressure >/=130/85 mm Hg; and waist circumference >102 cm in men or 88 cm in women). RESULTS: Among the 633 patients, 290 (46%) fulfilled the criteria for metabolic syndrome. Patients with metabolic syndrome were older and more likely to be women. Acute myocardial infarction characteristics and left ventricular ejection fraction rates were similar for both groups. In-hospital case fatality was higher in patients with metabolic syndrome compared with those without, as was the incidence of severe heart failure (Killip class >II). In multivariate analysis, metabolic syndrome was a strong and independent predictor of severe heart failure, but not in-hospital death. Analysis of the predictive value of each of the 5 metabolic syndrome components for severe heart failure showed that hyperglycemia was the major determinant (odds ratio, 3.31; 95% confidence interval, 1.86-5.87). CONCLUSIONS: In an unselected population of patients with AMI, the prevalence of metabolic syndrome was high. Metabolic syndrome appeared associated with worse in-hospital outcome, with a higher risk of development of severe heart failure. Among metabolic syndrome components, hyperglycemia was the main correlate of the risk of development of severe heart failure during AMI.

RESUMO

We report a case of deliberate ingestion of 12.5 g chloral hydrate in a 25-year-old psychiatric patient. Coma and life-threatening ventricular dysrhythmias were observed soon after ingestion. Repeated electrocardiographic examination was consistent with ischemic changes appearing on day 3. They were associated with segmental abnormal left ventricular wall motion by echocardiography. A coronary angiogram was performed and was normal. Toxic metabolites of chloral hydrate, trichloroethanol and trichloroacetic acid were found in the urine until day 7. This case illustrates that with halogenated aliphatic hydrocarbons, sustained changes in cardiac contractility may occur in addition to early life-threatening ventricular dysrhythmias.
