Introduction and objectives
There is little information on the use of transcatheter aortic valve implantation in patients with severe aortic stenosis and porcelain aorta. The primary aim of this study was to analyze death from any cause after CoreValve® implantation in patients with severe aortic stenosis, with and without porcelain aorta.Methods
In this multicenter, observational prospective study, carried out in 3 hospitals, percutaneous aortic valves were implanted in 449 patients with severely calcified aortic stenosis. Of these, 36 (8%) met the criteria for porcelain aorta. The primary end-point was death from any cause at 2 years.Results
Patients with porcelain aorta more frequently had extracardiac vascular disease (11 [30.6%] vs 49 [11.9%]; P=.002), prior coronary revascularization (15 [41.7%] vs 98 [23.7%]; P=.017), and dyslipidemia (26 [72.2%] vs 186 [45%]; P=.02). In these patients, there was greater use of general anesthesia (15 [41.7%] vs 111 [16.9%]; P=.058) and axillary access (9 [25%] vs 34 [8.2%]; P=.004). The success rate of the procedure (94.4 vs 97.3%; P=.28) and the incidence of complications (7 [19.4%] vs 48 [11.6%]; P=.20) were similar in both groups. There were no statistically significant differences in the primary end point at 24 months of follow-up (8 [22.2%] vs 66 [16%]; P=.33). The only predictive variable for the primary end point was the presence of complications during implantation (hazard ratio=2.6; 95% confidence interval, 1.5-4.5; P=.001).Conclusions
In patients with aortic stenosis and porcelain aorta unsuitable for surgery, percutaneous implantation of the CoreValve® self-expanding valve prosthesis is safe and feasible.Full English text available from: www.revespcardiol.org/en 相似文献2.

Introduction and objectives
The arterial switch operation is currently the preferred surgical approach for complete transposition of the great arteries. We sought to determine the mid-term results of this intervention.Methods
A single-institution retrospective review of clinical records of all consecutive patients who underwent the arterial switch surgery between 1985 and 2010.Results
Overall, the operation was performed on 155 patients (68% boys) at a median age of 13 days: 64% with an intact septum, 46% with a ventricular septal defect, and 4.5% with associated aortic arch anomaly. The usual coronary pattern was found in 63%. Palliative surgery was performed prior to arterial switch in 6.5%. In all, 137 perioperative survivors were followed for a median of 6 years. Late mortality was 2.9%, of which 50% was due to coronary complications. Eighteen percent required surgical and/or percutaneous reintervention: 95.6% for right-sided obstruction and 4.3% for aortic regurgitation. At last follow-up, 92% had functional class I symptoms and 95% were free of arrhythmias. The left ventricular ejection fraction was greater than 55% in 95%, 28% had neoaortic regurgitation (78% mild regurgitation), and 31% had right ventricular outflow tract obstruction with a mean gradient according to echocardiography greater than 25 mmHg.Conclusions
Mid-term survival of patients after arterial switch operation is excellent and their functional status is good. However, a few patients have residual lesions and a need for further intervention during follow-up, mostly for right-sided obstructions. Late mortality was uncommon and was related to coronary complications. Neoaortic root dilation and regurgitation are not major issues in early adulthood, but the long-term course of these lesions is still unknown.Full English text available from:www.revespcardiol.org/en 相似文献3.

Introduction and objectives
The prognostic value of chronic total occlusion in nonculprit coronary arteries in patients with myocardial infarction undergoing primary angioplasty remains controversial. Several publications have described different methodologies and conflicting findings. In addition, causes of death were not reported. Our aim is to analyze the prognostic impact of chronic total occlusion in nonculprit coronary arteries and the role of left ventricular ejection fraction in this analysis.Methods
Prospective inclusion of consecutive patients with ST-segment elevation myocardial infarction who underwent primary angioplasty. We recorded baseline characteristics, in-hospital clinical course, and mortality and its causes during follow-up. We assessed the impact of chronic total occlusion on mortality using Cox regression analysis.Results
Chronic total occlusion in nonculprit arteries was present in 125 of 1176 patients (10.6%); in 79 of these 125 patients, chronic total occlusion was present in the proximal segments. The mean follow-up was 339 days; 64 (5.8%) patients died during the first 6 months. Patients with chronic total occlusions had more comorbidities, poorer ventricular function, and higher mortality (hazard ratio=2.79; 95% confidence interval, 1.71-4.56). Chronic total occlusion was also associated with noncardiac death (hazard ratio=3.83; 95% confidence interval, 2.10-7.01). Chronic total occlusion in proximal segments was associated with both cardiac (hazard ratio=3.22; 95% confidence interval, 1.42-7.30) and noncardiac deaths (hazard ratio=3.43; 95% confidence interval, 1.67-7.06). The multivariate analysis performed without including left ventricular ejection fraction showed a significant association between chronic total occlusion and mortality. However, when left ventricular ejection fraction was included in the analysis, this association was nonsignificant (hazard ratio=1.76; 95% confidence interval, 0.85-3.65; P=.166).Conclusions
Chronic total occlusion in this clinical setting identified patients at higher risk with more comorbidities and higher mortality, but did not behave as an independent predictor of mortality when left ventricular ejection fraction was included in the analysis.Full English text available from:www.revespcardiol.org/en 相似文献4.

Introduction and objectives
Our objective was to assess the prognostic value of NT-proBNP in patients with asymptomatic moderate/severe aortic stenosis and to validate an adapted Monin score using natriuretic peptide levels in our setting.Methods
Prospective study of 237 patients with degenerative asymptomatic moderate/severe aortic stenosis. NT-proBNP was determined in all patients, who were then followed up clinically. The adapted Monin score was defined as follows: (peak velocity [m/s]×2)+(logn NT-proBNP×1.5)(+1.5 if woman). A clinical event was defined as surgery, hospital admission due to angina, heart failure or syncope, or death.Results
A total of 51% were women, and the mean age was 74 years. Mean (SD) echocardiographic values were as follows: peak velocity 4.14 (0.87) m/s; mean gradient, 43.2 (16.0) mmHg; aortic valve area, 0.87 (0.72) cm2, and aortic valve area index, 0.49 (0.14) cm2/m2. The median NT-pro-BNP value was 490.0 [198.0-1312.0] pg/mL. There were 153 events during follow-up (median 18 months). The optimum NT-proBNP cut-point was 515 pg/mL, giving event-free survival rates at 1 and 2 years of 93% and 57%, respectively, in patients with NT-proBNP <515 pg/mL compared with 50% and 31% in those with NT-proBNP >515 pg/mL. Patients were divided into quartiles based on the Monin score. Event-free survival at 1 and 2 years was 87% and 79% in the first quartile, compared with 45% and 28% in the fourth quartile, respectively.Conclusions
NT-proBNP determination provides prognostic information in patients with asymptomatic moderate/severe aortic stenosis. The adapted Monin score is useful in our setting and allows a more precise prognosis than does the use of NT-proBNP alone.Full English text available from:www.revespcardiol.org/en 相似文献5.

Introduction and objectives
Scarce research has been performed in ambulatory patients with chronic heart failure in the Mediterranean area. Our aim was to describe survival trends in our target population and the impact of prognostic factors.Methods
We carried out a population-based retrospective cohort study in Catalonia (north-east Spain) of 5659 ambulatory patients (60% women; mean age 77 [10] years) with incident chronic heart failure. Eligible patients were selected from the electronic patient records of primary care practices from 2005 and were followed-up until 2007.Results
During the follow-up period deaths occurred in 950 patients (16.8%). Survival after the onset of chronic heart failure at 1, 2, and 3 years was 90%, 80%, 69%, respectively. No significant differences in survival were found between men and women (P=.13). Cox proportional hazard modelling confirmed an increased risk of death with older age (hazard ratio=1.06; 95% confidence interval, 1.06-1.07), diabetes mellitus (hazard ratio=1.53; 95% confidence interval, 1.33-1.76), chronic kidney disease (hazard ratio=1.73; 95% confidence interval, 1.45-2.05), and ischemic heart disease (hazard ratio=1.18; 95% confidence interval, 1.02-1.36). Hypertension (hazard ratio=0,73; 95% confidence interval, 0,64-0,84) had a protective effect.Conclusions
Service planning and prevention programs should take into consideration the relatively high survival rates found in our area and the effect of prognostic factors that can help to identify high risk patients.Full English text available from:www.revespcardiol.org/en 相似文献6.

Introduction and objectives
It is uncertain whether side branch predilatation before main vessel stenting is necessary. We evaluated the effect of side branch predilatation on outcomes in percutaneous coronary intervention for true nonleft main bifurcation determined by the Medina classification using the provisional approach.Methods
Target vessel failures (composite of cardiac death, myocardial infarction, or target vessel revascularization) were compared between patients who underwent side branch predilatation (predilatation group, n = 175) and those who did not (nonpredilatation group, n = 662).Results
Final kissing-balloon inflation (57.1% vs 35.8%; P < .001) was performed more frequently and the cross-over rate to a 2-stent technique (14.9% vs 5.1%; P < .001) was higher in the predilatation group. During a median follow-up of 21 months, the predilatation group had a higher incidence of target vessel failures (14.3% vs 6.8%; P = .002) and target vessel revascularization (12.0% vs 5.6%; P = .003), but not of cardiac death or myocardial infarction compared with the nonpredilatation group. On multivariate analysis, side branch predilatation was associated with a higher occurrence of target vessel failures (adjusted hazard ratio = 2.11; 95% confidence interval, 1.27-3.50; P = .004). These results remained consistent after a propensity score-matched population analysis (for target vessel failures, adjusted hazard ratio = 2.63; 95% confidence interval, 1.09-6.34; P = .0031) and they were also constant among the various subgroups, according to the bifurcation angle, calcification, and diameter stenosis of the side branch.Conclusions
Side branch predilatation before main vessel stenting may be associated with an increased risk of repeat revascularization in patients with true nonleft main bifurcation treated by the provisional approach.Trial registration: ClinicalTrials.gov number: NCT00851526.Full English text available from: www.revespcardiol.org/en 相似文献8.

Introduction and objectives
Blood pressure measurement methods and conditions are determinants of hypertension diagnosis. A recent British guideline recommends systematic 24-h ambulatory blood pressure monitoring. However, these devices are not available at all health centers and they can only be used by 1 patient per day. The aim of this study was to test a new blood pressure recording method to see if it gave the same diagnostic results as 24-h blood pressure monitoring.Methods
One-hour blood pressure monitoring under routine clinical practice conditions was compared with standard method of day time recording by analyzing the coefficient of correlation and Bland-Altman plots. The Kappa index was used to calculate degree of agreement. Method sensitivity and specificity were also analyzed.Results
Of the 102 participants, 89 (87.3%) obtained the same diagnosis regardless of method, with high between-method agreement (κ= 0.81; 95% confidence interval, 0.71-0.91). We observed robust correlations between diastolic (r = 0.85) and systolic blood pressure (r = 0.76) readings. Sensitivity and specificity for the new method for diagnosing white coat hypertension were 85.2% (95% confidence interval 67.5%-94.1%) and 92% (95% confidence interval, 83.6%-96.3%), respectively.Conclusions
One-hour blood pressure monitoring is a valid and reliable method for diagnosing hypertension and for classifying hypertension subpopulations, especially in white coat hypertension and refractory hypertension. This also leads to a more productive use of monitoring instruments.Full English text available from:www.revespcardiol.org/en 相似文献9.

Introduction and objectives
The clinical impact of patient-prosthesis mismatch on the outcome in octogenarians who undergo surgery for aortic valve replacement due to severe stenosis is unknown. Our objective was to quantify the frequency of some degree of patient-prosthesis mismatch and its impact on mortality and life quality.Methods
We analyzed all the octogenarian patients who underwent surgery for aortic valve replacement due to severe stenosis in our center from February 2004 to April 2009. Patient-prosthesis mismatch was considered to exist when the indexed effective orifice area was ≤0.85 cm2/m2. The influence of patient-prosthesis mismatch on in-hospital mortality, medium-term survival, and New York Heart Association functional class was studied using an analysis adjusted for propensity score.Results
Of 149 patients studied, 61.7% had some degree of patient-prosthesis mismatch (mean follow-up was 32.71±14.42 months). After adjusting for propensity score, there were no differences in in-hospital mortality (odds ratio=0.75; 95% confidence interval, 0.15-3.58; P=.72), medium-term survival (hazard ratio=1; 95% confidence interval, 0.36-2.78; P=.99) or functional class during follow-up (odds ratio=1.46; 95% confidence interval, 0.073-29.24; P=.8).Conclusions
Although moderate patient-prosthesis mismatch is a very common finding in octogenarian patients who undergo aortic valve replacement, its influence on mortality and quality of life does not seem to be relevant. The biological profile of elderly patients with lower metabolic requirements and limited physical activity could justify the results obtained.Full English text available from: www.revespcardiol.org 相似文献12.

Introduction and objectives
Delayed diagnosis of hypertension may result in inadequate blood pressure control and increased cardiovascular risk. The aim of this study was to estimate the delay in hypertension diagnosis in patients with type 2 diabetes and the likelihood of a diagnosis within a suitable period (first 6 months), and to analyze the patient and physician characteristics associated with delayed diagnosis.Methods
Retrospective dynamic cohort study, with a 7-year follow-up in primary care, of 8074 adult patients with diabetes who met the diagnostic criteria for hypertension. Two thresholds were considered: 140/90 mmHg and 130/80 mmHg. The time elapsed between meeting these criteria and recording the diagnosis was estimated; the time course of the likelihood of a missed diagnosis and the variables associated with correct diagnosis were assessed by Kaplan-Meier survival analysis and logistic regression analysis, respectively.Results
The mean diagnostic delay was 8.9 (15.4) months in patients with blood pressure≥140/90 mmHg compared to 15.2 (19.6) months for those with <140/90 mmHg (P<.001). The main variables associated with correct diagnosis were baseline blood pressure ≥140/90 mmHg (odds ratio=2.77; 95% confidence interval, 2.44-3.15), no history of acute myocardial infarction (odds ratio=2.23; 95% confidence interval, 1.67-2.99), obesity (odds ratio=1.70; 95% confidence interval, 1.44-1.99), absence of depression (odds ratio=1.63; 95% confidence interval, 1.27-2.08), female sex (odds ratio=1.29; 95% confidence interval, 1.14-1.46), older age, and taking more intensive antidiabetic therapy. There was an inverse relationship with the age of physicians and a direct relationship with their professional stability.Conclusions
The mean diagnostic delay in hypertension among diabetic patients was greater than 6 months and varied according to the diagnostic threshold used. Patients with baseline blood pressure≥140/90 mmHg were more likely to receive a timely diagnosis.Full English text available from:www.revespcardiol.org/en 相似文献13.

Introduction and objectives
Urokinase-type plasminogen activator, which is encoded by the PLAU gene, plays a prominent role during collateral arterial growth. We investigated whether the PLAU P141L (C > T) polymorphism, which causes a mutation in the kringle domain of the protein, is associated with coronary collateral circulation in a cohort of 676 patients with coronary artery disease.Methods
The polymorphism was genotyped in blood samples using a TaqMan-based genotyping assay, and collateral circulation was assessed by the Rentrop method. Multivariate logistic regression models adjusted by clinically relevant variables to estimate odds ratios were used to examine associations of PLAU P141L allelic variants and genotypes with collateral circulation.Results
Patients with poor collateral circulation (Rentrop 0-1; n = 547) showed a higher frequency of the TT genotype than those with good collateral circulation (Rentrop 2-3; n = 129; P = .020). The T allele variant was also more common in patients with poor collateral circulation (P = .006). The odds ratio of having poorly developed collaterals in patients bearing the T allele (adjusted for clinically relevant variables) was statistically significant under the dominant model (odds ratio =1.83 [95% confidence interval, 1.16-2.90]; P = .010) and the additive model (odds ratio =1.73 [95% confidence interval, 1.14-2.62]; P = .009).Conclusions
An association was found between coronary collateral circulation and the PLAU P141L polymorphism. Patients with the 141L variant are at greater risk of developing poor coronary collateral circulation.Full English text available from: www.revespcardiol.org/en 相似文献14.

Introduction and objectives
The objectives of this study were to analyze the association between two genetic variants (rs2200733 and rs7193343) in a Spanish population and the risk of developing atrial fibrillation, and to carry out a systematic review and meta-analysis of these associations.Methods
We performed a case-control study involving 257 case patients with atrial fibrillation and 379 controls. The case patients were individuals who had donated samples to the Spanish National DNA Bank; the controls were participating in a population-based cross-sectional study. Genotyping was carried out using a TaqMan assay. We conducted a systematic literature search in which 2 independent reviewers extracted the necessary information. The study involved a meta-analysis, a heterogeneity analysis, and a meta-regression analysis to identify the variables that explain the heterogeneity across studies.Results
In our population, the presence of atrial fibrillation was found to be associated with rs2200733 (odds ratio = 1.87; 95% confidence interval, 1.30-2.70), but not with rs7193343 (odds ratio = 1.18; 95% confidence interval, 0.80-1.73). In the meta-analysis, we observed an association between atrial fibrillation and both variants: odds ratio = 1.71 (95% confidence interval, 1.54-1.90) for rs2200733 and odds ratio = 1.18 (95% confidence interval, 1.11-1.25) for rs7193343. We observed heterogeneity among the studies dealing with the association between rs2200733 and atrial fibrillation, partially related to the study design, and the strength of association was greater in case-control studies (odds ratio = 1.83) than in cohort studies (odds ratio = 1.41).Conclusions
Variants rs2200733 and rs7193343 are associated with a higher risk of atrial fibrillation. Case-control studies tend to overestimate the strength of association between these genetic variants and atrial fibrillation.Full English text available from:www.revespcardiol.org/en 相似文献15.

Background
The diagnosis of pulmonary embolism (PE) is often complicated by the presence of chronic obstructive pulmonary disease (COPD). Some studies have suggested that patients with PE and concomitant COPD have a worse prognosis than patients without COPD.Patients and methods
Outpatients diagnosed with acute symptomatic PE at a university tertiary care hospital were prospectively included in the study. Clinical characteristics, time between onset of symptoms and diagnosis, and outcome were analyzed according to presence or absence of COPD. The primary endpoint was all-cause deaths at 3 months.Results
Of 882 patients with a confirmed diagnosis of acute symptomatic PE, 8% (95% confidence interval [CI], 6%–9%) had COPD. Patients with COPD were significantly more likely to have a delay in diagnosis of more than 3 days and to have a low pretest probability of pulmonary embolism according to a standardized clinical score. The total number of deaths during 3 months of follow-up was 128 (14%; 95% CI, 12%–17%). Factors significantly associated with mortality from all causes were a history of cancer or immobilization, systolic blood pressure less than 100 mm Hg, and arterial oxyhemoglobin saturation less than 90%. COPD was significantly associated with PE-related death in the logistic regression analysis (relative risk, 2.2; 95% CI, 1.0–5.1).Conclusions
Patients with COPD and PE more often have a lower pretest probability and a longer delay in diagnosis of PE. COPD is significantly associated with PE-related death in the 3 months following diagnosis. 相似文献16.

Introduction and objectives
In patients with heart failure, left ventricular ejection fraction ≤35% and sinus rhythm without conditions such as atrial fibrillation, thrombus or history of thromboembolic events, the use of anticoagulation is controversial. Our objective was to evaluate the anticoagulation strategy in these patients, variables associated with its use, and its effects on various cardiovascular events.Methods
Of the patients included in the REDINSCOR registry with left ventricular ejection fraction ≤35% and sinus rhythm without other anticoagulation indications (including patients with heart failure from 19 Spanish centres), we compared those who received this treatment with the remaining patients.Results
Between 2007 and 2010, 2263 patients were included, of whom 902 had left ventricular ejection fraction ≤35% and sinus rhythm. Of these, 237 (26%) were receiving anticoagulation therapy. Variables associated with this treatment were a lower left ventricular ejection fraction, ischemic etiology, advanced functional class, wider QRS, larger left atrial diameter, and hospitalization. After 21(11-32) months of median follow-up, there were no significant differences in total mortality (14% versus 12.5%) or stroke (0.8% versus 0.9%). A propensity score adjusted multivariate analysis showed a reduction in a combined end-point including cardiac death, heart transplantation, coronary revascularization, and cardiovascular hospitalization (hazard ratio: 0.74; 95% confidence interval, 0.56-0.97; P=.03) in patients receiving anticoagulation therapy. No information regarding bleeding was collected in the follow-up.Conclusions
In a large and contemporary series of patients with heart failure, left ventricular ejection fraction ≤35% and sinus rhythm, 26% received anticoagulation therapy. This was not associated with lower mortality or stroke incidence, although there was a reduction in major cardiac events.Full English text available from:www.revespcardiol.org 相似文献17.

Introduction and objectives
Peritoneal dialysis has been proposed as a therapeutic alternative for patients with refractory congestive heart failure. The objective of this study was to assess its effect on long-term clinical outcomes in patients with advanced heart failure and renal dysfunction.Methods
A total of 62 patients with advanced heart failure (class III/IV), renal dysfunction (glomerular filtration<60 mL/min/1.73 m2), persistent fluid congestion despite loop diuretic treatment and at least 2 previous hospitalizations for heart failure were invited to participate in a continuous ambulatory peritoneal dialysis program. Of these, 34 patients were excluded and adjudicated as controls. The most important reasons for exclusion were refusal to participate, inability to perform the technique and abdominal wall defects. The primary endpoint was all-cause mortality and the composite of death/readmission for heart failure. To account for baseline imbalance, a propensity score was estimated and used as a weight in all analyses.Results
The peritoneal dialysis (n=28) and control groups (n=34) were alike in all baseline covariates. During a median follow-up of 16 months, 39 (62.9%) died, 21 (33.9%) patients were rehospitalization for heart failure, and 42 (67.8%) experienced the composite endpoint. In the propensity score-adjusted models, peritoneal dialysis (vs control group) was associated with a substantial reduction in the risk of mortality using complete follow-up (hazard ratio=0.40; 95% confidence interval, 0.21-0.75; P=.005), mortality using days alive and out of hospital (hazard ratio=0.39; 95% confidence interval, 0.21-0.74; P=.004) and the composite endpoint (hazard ratio=0.32; 95% confidence interval, 0.17-0.61; P=.001).Conclusions
In refractory congestive heart failure with concomitant renal dysfunction, peritoneal dialysis was associated with long-term improvement in clinical outcomes.Full English text available from:www.revespcardiol.org 相似文献18.

Introduction and objectives
High baseline levels of interleukin-6 and C-reactive protein confer an increased risk of mortality in non-ST-segment elevation acute coronary syndrome. The aim of the study was to determine whether serial measurements of interleukin-6 and high-sensitivity C-reactive protein provide additional information to baseline measurements for risk stratification of non-ST-segment elevation acute coronary syndrome.Methods
Two hundred and sixteen consecutive patients with non-ST-segment elevation acute coronary syndrome were prospectively included. Blood samples were obtained within 24 h of hospital admission and at 30 days of follow-up. The endpoint was a composite of all-cause death, nonfatal myocardial infarction, or acute decompensated heart failure.Results
Both interleukin-6 and high-sensitivity C-reactive protein levels decreased from day 1 to day 30, regardless of adverse events (both P<.001). Interleukin-6 levels at 2 time points (interleukin-6 day 1, per pg/mL; hazard ratio=1.006, 95% confidence interval, 1.002-1.010; P=.002 and interleukin-6 day 30, per pg/mL; hazard ratio=1.047, 95% confidence interval, 1.021-1.075; P<.001) were independent predictors of adverse events, whereas high-sensitivity C-reactive protein day 1 and high-sensitivity C-reactive protein day 30 levels were not. Patients with interleukin-6 day 1≤8.24 pg/mL and interleukin-6 day 30≤4.45 pg/mL had the lowest event rates (4.7%), whereas those with both above the median values had the highest event rates (35%). After addition of interleukin-6 day 30 to the multivariate model, C-index increased from 0.71 (95% confidence interval, 0.63-0.78) to 0.80 (95% confidence interval, 0.72-0.86), P=.042, and net reclassification improvement was 0.39 (95% confidence interval, 0.14-0.64; P=.002).Conclusions
In this population, both interleukin-6 and high-sensitivity C-reactive protein concentrations decreased after the acute phase. Serial samples of interleukin-6 concentrations improved the prognostic risk stratification of these patients.Full English text available from:www.revespcardiol.org/en 相似文献19.

Introduction and objectives
To analyze sex-based differences in clinical characteristics, management, and 28-day and 7-year prognosis after a first myocardial infarction.Methods
Between 2001 and 2003, 2042 first myocardial infarction patients were consecutively registered in 6 Spanish hospitals. Clinical characteristics, management, and 28-day case-fatality were prospectively recorded. Seven-year vital status was also ascertained by data linkage with the National Mortality Index.Results
The registry included 449 women and 1593 men with a first myocardial infarction. Compared with men, women were older, had a higher prevalence of hypertension and diabetes, and were more likely to receive angiotensin-converting enzyme inhibitors but were less likely to receive beta-blockers or thrombolysis. No differences were observed in use of invasive procedures. More women had non-ST-segment elevation and unclassified myocardial infarction than men (37.9% vs 31.3% and 9.8% vs 6.1%, respectively; both P<.001). Case-fatality at 28 days was similar in women and men (5.57% vs 4.46%; P=.39). After multivariate adjustment, the odds ratio of 28-day mortality for men was 1.06 (95% confidence interval: 0.49-2.27; P=.883) compared with women. After multivariate adjustment, men had higher 7-year mortality than women, hazard ratio 1.93 (95% confidence interval: 1.46-2.56; P<.001).Conclusions
There are demographic and clinical differences between men and women with a first myocardial infarction. The short-term prognosis of a first myocardial infarction in this century is similar in both sexes. However, the long-term vital prognosis after a first myocardial infarction is worse in men than in women. These results are observed in both ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction events.Full English text available from:www.revespcardiol.org/en 相似文献20.
