Introduction and objectives
Smoking is one of the most prevalent risk factors in acute coronary syndrome patients. The aim of this study was to assess the attitudes of cardiologists to the smoking habits of these patientsMethods
A prospective multicenter registry of acute coronary syndrome patients. The primary endpoint was defined as smoking abstinence and the secondary endpoint as the incidence of all-cause mortality or nonfatal myocardial infarction.Results
The study population included 715 patients; 365 were current smokers. During follow-up (median, 375,0 days [interquartile range, 359.3-406.0 days]), 110 patients (30.6%) received smoking cessation support (19.7% at hospital discharge and 37.6% at month 3), specialized units and varenicline being the strategies most frequently used. No clinical differences were observed between patients who received smoking cessation support and those who did not, except for a higher prevalence of previous coronary heart disease in those who received support. In the multivariate analysis, the only variable independently associated with receiving smoking cessation support was previous coronary heart disease (odds ratio =3.16; 95% confidence interval, 1.64-6.11; P<.01). The abstinence rate was 72.3% at month 3 and 67.9% at 1 year; no differences were observed between the patients who received smoking cessation support and those who did not. During follow-up, a nonsignificant trend toward a lower incidence of the secondary endpoint was observed among the patients who were smokers at the time of acute coronary syndrome and who achieved abstinence (P=.07).Conclusions
Use of smoking cessation support strategies is limited in acute coronary syndrome patients and is more widespread among those with previous coronary heart disease.Full English text available from:www.revespcardiol.org 相似文献2.

Introduction and objectives
We performed a pooled analysis based on patient-level data from the TITAX-AMI and BASE-ACS trials to evaluate the outcome of titanium-nitride-oxide-coated bioactive stents vs drug-eluting stents in patients with ST-segment elevation myocardial infarction at 2-year follow-up.Methods
The TITAX-AMI trial compared bioactive stents with paclitaxel-eluting stents in 425 patients with acute myocardial infarction. The BASE-ACS trial compared bioactive stents with everolimus-eluting stents in 827 patients with acute coronary syndrome. The primary endpoint for the pooled analysis was major adverse cardiac events: a composite of cardiac death, recurrent myocardial infarction, or ischemia-driven target lesion revascularization at 2-year follow-up.Results
The pooled analysis included 501 patients; 245 received bioactive stents, and 256 received drug-eluting stents. The pooled bioactive stent group was associated with a risk ratio of 0.85 for major adverse cardiac events (95% confidence interval, 0.53-1.35; P = .49) compared to the pooled drug-eluting stent group. Similarly, the pooled bioactive stent group was associated with a risk ratio of 0.71 for cardiac death (95% confidence interval, 0.26-1.95; P = .51), 0.44 for recurrent myocardial infarction (95% confidence interval, 0.20-0.97; P = .04), and 1.39 for ischemia-driven target lesion revascularization (95% confidence interval, 0.74-2.59; P = .30), compared to the pooled drug-eluting stent group. These results were confirmed by propensity-score adjusted analysis of the combined datasets.Conclusions
In patients with ST-segment elevation myocardial infarction, bioactive stents were associated with lower rates of recurrent myocardial infarction compared to drug-eluting stents at 2-year follow-up; yet, the rates of cardiac death and ischemia-driven target lesion revascularization were similar.Full English text available from: www.revespcardiol.org/en 相似文献3.

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4.

Introduction and objectives
Quantification of myocardial area-at-risk after acute myocardial infarction has major clinical implications and can be determined by cardiovascular magnetic resonance. The Bypass Angioplasty Revascularization Investigation Myocardial Jeopardy Index (BARI) and Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease (APPROACH) angiographic scores have been widely used for rapid myocardial area-at-risk estimation but have not been directly validated. Our objective was to compare the myocardial area-at-risk estimated by BARI and APPROACH angiographic scores with those determined by cardiovascular magnetic resonance.Methods
In a prospective study, cardiovascular magnetic resonance was performed in 70 patients with a first successfully-reperfused ST-segment elevation acute myocardial infarction in the first week after percutaneous coronary intervention. Myocardial area-at-risk was obtained both by analysis of T2-short tau inversion recovery sequences and calculation of infarct endocardial surface area with late enhancement sequences. These results were compared with those of BARI and APPROACH scores.Results
BARI and APPROACH showed a statistically significant correlation with T2-short tau inversion recovery for myocardial area-at-risk estimation (BARI, intraclass correlation coefficient=0.72; P<.001; APPROACH, intraclass correlation coefficient=0.69; P<.001). Better correlations were observed for anterior acute myocardial infarction than for other locations (BARI, intraclass correlation coefficient=0.73 vs 0.63; APPROACH, intraclass correlation coefficient=0.68 vs 0.50). Infarct endocardial surface area showed a good correlation with both angiographic scores (BARI, intraclass correlation coefficient=0.72; P<.001; with APPROACH, intraclass correlation coefficient=0.70; P<.001).Conclusions
BARI and APPROACH angiographic scores allow reliable estimation of myocardial area-at-risk in current clinical practice, particularly in anterior infarctions.Full English text available from:www.revespcardiol.org 相似文献5.

Introduction and objectives
A standardized protocol of emergent transfer for primary percutaneous coronary intervention for patients with ST elevation myocardial infarction, defined as the Infarction Code, was implemented in June 2009 in the Catalan regional health system. The objective of this study was to evaluate the impact of the new protocol on delay times, number of procedures and clinical characteristics compared with the previous period in the population of patients referred to our hospital.Methods
All consecutive patients undergoing primary percutaneous coronary intervention in our hospital were prospectively registered. The clinical characteristics, delay times and mortality in the follow-up of the protocol implementation period (June 2009-May 2010) were analyzed and compared with the previous year (June 2008-May 2009).Results
During the protocol period, 514 patients were included, compared with 241 in the previous year. Age, cardiovascular risk factors, anterior myocardial infarction and procedure characteristics were similar in the 2 groups. The first medical contact to balloon time was lower in the protocol period (median time 120 min vs 88 min; P<.001). Patients in the protocol period showed a trend toward less severe disease (Killip III, rescue angioplasty). The multivariate regression analysis showed a significant association between 1-year mortality and age, Killip class≥ III at admission, anterior infarction and 3-vessel disease.Conclusions
The introduction of the Infarction Code program increased the number of patients treated by primary percutaneous coronary intervention with a reduction in delay times and better clinical characteristics at presentation.Full English text available from:www.revespcardiol.org 相似文献6.
Introduction and objectives
Coronary heart disease is the second cause of death in Chilean women, with higher mortality among women, especially at younger ages. The objective was to analyze in-hospital case-fatality by sex and age in patients with acute myocardial infarction in Chile and to evaluate associated factors.Methods
From the nationwide hospital admissions database and the GEMI registry (a multicenter registry), we selected all cases of acute myocardial infarction (code: I.21) that occurred between 2001 and 2007 in Chile. We estimated odds ratios for in-hospital case-fatality in women by age (crude and adjusted for clinical characteristics and treatment).Results
In total, 49 287 cases of acute myocardial infarction were hospitalized, 31.3% of them women; 9278 patients were incorporated in the GEMI registry (27.1% women). In-hospital case-fatality was higher (P<.001) in women than men (national database, 20.4% vs 11.3%; GEMI, 14.2% vs 7.3%, irrespective of age. In-hospital case-fatality risk was higher in women aged<45 years: national odds ratio=2.3 (95% confidence interval, 1.5-3.3) and GEMI, odds ratio=2.7 (1.1-6.8). The estimated risk was lower in women aged 75 or more years in both databases, 1.3 (1.2-2.4) and 1.5 (1.2-1.9), respectively. Younger women less often received statins, odds ratio=0.7 (0.6-0.8); acetylsalicylic acid, odds ratio=0.4 (0.2-0.6); betablockers, odds ratio=0.8 (0.6-0.9), and thrombolytics, odds ratio=0.6 (0.5-0.8). An interaction was found between Killip class and sex. After adjusting for covariates, women aged<55 years with ST-segment elevation myocardial infarction and Killip class I-II, had the highest risk, odds ratio=4.3 (2.1-8.9).Conclusions
In the context of a Latin American country, women aged<55 years with ST-segment elevation myocardial infarction and Killip class I-II had a higher risk of death. Known risk factors do not completely explain this excess of risk.Full English text available from:www.revespcardiol.org/en. 相似文献7.

Introduction and objectives
To compare the 3-year incidence of major events in patients with bifurcation lesions treated with provisional sirolimus-eluting stents vs everolimus-eluting stents.Methods
A pooled analysis of 2 prospective randomized trials with similar methodology (SEAside and CORpal) was performed. In these trials, 443 patients with bifurcation lesions were randomly assigned to treatment with either sirolimus-eluting stents or everolimus-eluting stents. The clinical follow-up was extended up to 3 years to assess major adverse cardiovascular events (death or acute myocardial infarction or target vessel revascularization).Results
At 3 years, survival free of major adverse cardiovascular events was 93.2% vs 91.3% in the everolimus-eluting stent group vs the sirolimus-eluting stent group (P = .16). Exploratory land-mark analysis for late events (occurring after 12 months) showed significantly fewer major adverse cardiovascular events in the everolimus-eluting stent group: 1.4% vs 5.4% in the sirolimus-eluting stent group (P = .02).Conclusions
Provisional stenting with either sirolimus-eluting stents or everolimus-eluting stents in bifurcation lesions is associated with low rates of major adverse events at 3-years’ follow-up. The results of a subanalysis of events beyond 1 year, showing a lower event rate with everolimus-eluting stents than with sirolimus-eluting stents, suggest that studies exploring the long-term clinical benefit of the latest generation of drug-eluting stents are warranted.Full English text available from: www.revespcardiol.org/en 相似文献8.

Introduction and objectives
A variety of cardiac magnetic resonance indexes predict mid-term prognosis in ST-segment elevation myocardial infarction patients. The extent of transmural necrosis permits simple and accurate prediction of systolic recovery. However, its long-term prognostic value beyond a comprehensive clinical and cardiac magnetic resonance evaluation is unknown. We hypothesized that a simple semiquantitative assessment of the extent of transmural necrosis is the best resonance index to predict long-term outcome soon after a first ST-segment elevation myocardial infarction.Methods
One week after a first ST-segment elevation myocardial infarction we carried out a comprehensive quantification of several resonance parameters in 206 consecutive patients. A semiquantitative assessment (altered number of segments in the 17-segment model) of edema, baseline and post-dobutamine wall motion abnormalities, first pass perfusion, microvascular obstruction, and the extent of transmural necrosis was also performed.Results
During follow-up (median 51 months), 29 patients suffered a major adverse cardiac event (8 cardiac deaths, 11 nonfatal myocardial infarctions, and 10 readmissions for heart failure). Major cardiac events were associated with more severely altered quantitative and semiquantitative resonance indexes. After a comprehensive multivariate adjustment, the extent of transmural necrosis was the only resonance index independently related to the major cardiac event rate (hazard ratio=1.34 [1.19-1.51] per each additional segment displaying >50% transmural necrosis, P<.001).Conclusions
A simple and non-time consuming semiquantitative analysis of the extent of transmural necrosis is the most powerful cardiac magnetic resonance index to predict long-term outcome soon after a first ST-segment elevation myocardial infarction.Full English text available from: www.revespcardiol.org/en 相似文献9.

Introduction and objectives
The angiographic and clinical efficacy of polymer-free sirolimus-eluting stents vs polymer-based paclitaxel-eluting stents remain a matter of debate. We sought to investigate angiographic and clinical measures of efficacy of polymer-free sirolimus-eluting stents vs polymer-based paclitaxel-eluting stents.Methods
Patient data from the randomized intracoronary stenting and angiographic restenosis-test equivalence between the 2 drug-eluting stents (ISAR-TEST) clinical trial and the LIPSIA Yukon clinical trial (randomized comparison of a polymer-free sirolimus-eluting stent vs a polymer-based paclitaxel-eluting stent in patients with diabetes mellitus) were pooled. The angiographic (primary) endpoint was in-stent late lumen loss at 6 months to 9 months. The clinical (secondary) endpoints were death or myocardial infarction, cardiac death or myocardial infarction, target lesion revascularization, and myocardial infarction.Results
A total of 686 patients (polymer-free sirolimus-eluting stents, n=345 vs polymer-based paclitaxel-eluting stents, n=341) and 751 lesions (polymer-free sirolimus-eluting stents, n=383 vs polymer-based paclitaxel-eluting stents, n=368) were included in the study. Control angiography (606 lesions, 80.6%) showed comparable in-stent late lumen loss for polymer-free sirolimus-eluting stents vs polymer-based paclitaxel-eluting stents (0,53 [0,59] mm vs 0,46 [0,57] mm; P=.15). Median follow-up was 34.8 months. Polymer-free sirolimus-eluting stents and polymer-based paclitaxel-eluting stents were associated with comparable risk of death or myocardial infarction (relative risk=1.17; 95% confidence interval, 0,49-2.80; P=.71), cardiac death or myocardial infarction (relative risk=1.17; 95% confidence interval, 0,72-1.89; P=.50), target lesion revascularization (relative risk=0,98; 95% confidence interval, 0,65-1.47; P=.93), and myocardial infarction (relative risk=1.79; 95% confidence interval, 0,85-3.76; P=.12).Conclusions
In this pooled analysis, polymer-free sirolimus-eluting stents were comparable to polymer-based paclitaxel-eluting stents with respect to both angiographic and clinical efficacy.Full English text available from:www.revespcardiol.org. 相似文献10.

Introduction and objectives
Acute myocardial infarction is responsible for most of the deaths in developed countries and for a very large number of hospital admissions. Specifically in Spain, each year about 140 000 deaths and 5 million hospital stays are due to acute myocardial infarction, corresponding to health care costs reaching 15% of total expenditure. Therefore, this paper presents an exhaustive analysis of acute myocardial infarction and the related prognosis, such as recurrence and mortality.Methods
This observational study was carried out in Spain. Data were obtained using the Hospital Discharge Administrative Database from 2000 through 2007, inclusive. Specifically, 12 096 cases of acute myocardial infarction (8606 women and 3490 men) were reported during this period, with 2395 readmissions for this diagnosis. Readmissions were analyzed for frequency and duration using logistic regression and the Wang survival model. Mortality was analyzed using logistic regression.Results
Readmission rates were 50% for patients younger than 45 years and 38% for those older than 75 years (P<.001). Men were readmitted more frequently than women throughout the follow-up period. Variables related to hospital mortality from acute myocardial infarction were the presence of diabetes, previous ischemic heart disease, and cerebrovascular disease.Conclusions
Mid-term hospital readmissions are highly frequent in acute myocardial infarction survivors. Male sex, previous coronary heart disease, and the number of classical cardiovascular risk factors are the major risk predictors of this readmission. Our results highlight the need for improved medical care during acute myocardial infarction admission, integrated into secondary prevention programs.Full English text available from:www.revespcardiol.org 相似文献11.

Introduction and objectives
Oxygen saturation by pulse oximetry is commonly used for monitoring critical patients, but its utility as a diagnostic marker of acute heart failure has not been assessed. This study analyzed the diagnostic role of oxygen saturation by pulse oximetry in a series of patients with acute myocardial infarction.Methods
In a prospective observational cohort study of 220 consecutive patients with acute myocardial infarction, data collection included baseline oxygen saturation by pulse oximetry (without oxygen), physiologic measurements, Killip class and data from portable chest radiography, recorded at the same hour on each of the first three days after admission. Patients were followed up for one year.Results
There were 612 assessments. Baseline oxygen saturation by pulse oximetry decreased progressively in relation to the presence and the severity of acute heart failure assessed by Killip classes 1 to 3 (mean: 95, 92 and 85, respectively; P<.001) or by Radiology Score 0 to 4 (95, 94, 92, 89 and 83, respectively; P<.001), with a correlation coefficient of 0.66 and 0.63, respectively. Receiver operating characteristic curves disclosed the cut-off of oxygen saturation by pulse oximetry<93 to have the greatest area, with a sensitivity of 65%, specificity 90%, and overall test accuracy 83%. Patients grouped according to lowest oxygen saturation by pulse oximetry showed significantly different rates of one-year mortality or rehospitalization for heart failure.Conclusions
Baseline oxygen saturation by pulse oximetry is useful in establishing the diagnosis and severity of heart failure in acute settings such as myocardial infarction and may have prognostic implications.The diagnosis may be suspected when baseline oxygen saturation by pulse oximetry is <93.Full English text available from:www.revespcardiol.org 相似文献12.

Background
Acute myocardial infarction is the most dangerous complication of coronary atherothrombosis. There are several disparities in regard to its management around the world. The aim of this study is to analyze the specificities of management of acute myocardial infarction in Morocco.Methods
FES-AMI (Fès Acute Myocardial Infarction) is a prospective monocentric registry conducted in cardiology department of Hassan II university hospital in Fès. In this registry, we enrolled patients with acute myocardial infarction who presented within 5 days after symptom onset.Results
From January 2005 to August 2015, we enrolled 1835 patients. Seventy-five percent of patients were males and mean age was 60 years old. Fifty-one percent of patients were smokers, 27% were hypertensives and 14% were diabetics. Sixty-six percent of patients had more than 2 risk factors. Time from symptom onset to hospital admission was less than six hours for 40% of the patients. Thirty-six percent of patients were admitted more than twelve hours after the onset of chest pain. Only 37% of patients received reperfusion therapy, 31% with in-hospital thrombolysis and 6% with primary angioplasty. In-hospital mortality was 7.6%.Conclusion
The patients enrolled in our registry have late presentation of acute myocardial infarction and less rate of reperfusion therapy. Furthermore, the majority of our patients have multiple risk factors and this result underlines the failure of preventive interventions. 相似文献13.

Introduction and objectives
Encouraging results at long-term follow-up have been reported from non-randomized registries and randomized trials following percutaneous coronary intervention with drug-eluting stent implantation for unprotected left main stenosis. However, information on very long-term (>5-year) outcomes is limited. The aim of this study was to assess the very long-term outcomes (6-years) following drug-eluting stent implantation for left main disease.Methods
All consecutive patients with unprotected left main stenosis electively treated with drug-eluting stent implantation, between March 2002 and May 2005, were analyzed according to the location of the left main lesion (distal bifurcation vs ostial/body).Results
The study included 149 patients: 113 with distal bifurcation and 36 with ostial/body lesion. Triple-vessel disease was significantly higher in the distal than in the ostial/body group (52.2% vs 33.2%, P=.05). At 6-years of follow-up, the cumulative major adverse cardiovascular event rate was 41.6% (45.1% distal vs 30.6% ostial/body, P=0.1), including 18.8% any death (22.1% distal vs 8.3% ostial/body, P=.08), 3.4% myocardial infarction (3.5% distal vs 2.8% ostial/body, P=1), and 15.4% target lesion revascularization (18.6% distal vs 5.6% ostial/body, P=.06). The composite of cardiac death and myocardial infarction was 10.7% (13.3% distal vs 2.8% ostial/body, P=.1) while the definite/probable stent thrombosis rate was 1.4% (all in the distal group).Conclusions
At 6-year clinical follow-up, percutaneous coronary intervention with drug-eluting stent implantation for unprotected left main disease was associated with acceptable rates of cardiac death, myocardial infarction and stent thrombosis. Favorable long-term outcomes in ostial/body lesions compared to distal bifurcation lesions were confirmed at long-term clinical follow-up.Full English text available from:www.revespcardiol.org/en 相似文献14.

Introduction and objectives
Patients with a current acute coronary syndrome and previous ischemic heart disease, peripheral arterial disease, or cerebrovascular disease are reported to have a poorer outcome than those without these previous conditions. It is uncertain whether this association with outcome is observed at long-term follow-up.Methods
Prospective observational study, including 4247 patients with ST-segment elevation myocardial infarction. Detailed clinical data and information on previous ischemic heart disease, peripheral arterial disease, and cerebrovascular disease («vascular burden») were recorded. Multivariate models were performed for in-hospital and long-term (median, 7.2 years) all-cause mortality.Results
One vascular territory was affected in 1131 (26.6%) patients and ≥ 2 territories in 221 (5.2%). The total in-hospital mortality rate was 12.3% and the long-term incidence density was 3.5 deaths per 100 patient-years. A background of previous ischemic heart disease (odds ratio = 0.83; P = .35), peripheral arterial disease (odds ratio = 1.30; P=.34), or cerebrovascular disease (stroke) (odds ratio = 1.15; P = .59) was not independently predictive of in-hospital death. In an adjusted model, previous cerebrovascular disease and previous peripheral arterial disease were both predictors of mortality at long-term follow-up (hazard ratio = 1.57; P < .001; and hazard ratio = 1.34; P = .001; respectively). Patients with ≥ 2 diseased vascular territories showed higher long-term mortality (hazard ratio = 2.35; P < .001), but not higher in-hospital mortality (odds ratio = 1.07; P = .844).Conclusions
In patients with a diagnosis of ST-segment elevation acute myocardial infarction, the previous vascular burden determines greater long-term mortality. Considered individually, previous cerebrovascular disease and peripheral arterial disease were predictors of mortality at long-term after hospital discharge.Full English text available from: www.revespcardiol.org/en 相似文献15.

Background
There are limited data informing the optimal treatment strategy for acute myocardial infarction in the oldest old (aged ≥85 years). The study aim was to examine whether decade-long increases in guideline-based cardiac medication use mediate declines in post-discharge mortality among oldest old patients hospitalized with acute myocardial infarction.Methods
The study sample included 1137 patients aged ≥85 years hospitalized in 6 biennial periods between 1997 and 2007 for acute myocardial infarction at all 11 greater Worcester, Massachusetts, medical centers. We examined trends in 90-day survival after hospital discharge and guideline-based medication use (aspirin, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers, lipid-lowering agents) for acute myocardial infarction during hospitalization and at discharge. Sequential multivariable Cox regression models examined the relationship among guideline-based medication use, study year, and 90-day post-discharge survival rates.Results
Patients hospitalized between 2003 and 2007 experienced higher 90-day survival rates than those hospitalized between 1997 and 2001 (69.1% vs 59.8%, P < .05). Between 1997 and 2007, the average number of guideline-based medications prescribed at discharge increased significantly (1.8 to 2.9, P < .001). The unadjusted hazard ratio for 90-day post-discharge mortality in 2003-2007 compared with 1997-2001 was 0.73 (95% confidence interval, 0.60-0.89); after adjustment for patient characteristics and guideline-based cardiac medication use, this relationship was no longer significant (hazard ratio, 1.26; 95% confidence interval, 1.00-1.58).Conclusions
Between 1997 and 2007, 90-day survival improved among a population-based sample of patients aged ≥85 years hospitalized for acute myocardial infarction. This encouraging trend was explained by increased use of guideline-based medications. 相似文献16.

Introduction and objectives
There is extensive controversy exists on whether cardiac resynchronization therapy corrects electrical or mechanical asynchrony. The aim of this study was to determine if there is a correlation between electrical and mechanical sequences and if myocardial scar has any relevant impact.Methods
Six patients with normal left ventricular function and 12 patients with left ventricular dysfunction and left bundle branch block, treated with cardiac resynchronization therapy, were studied. Real-time three-dimensional echocardiography and electroanatomical mapping were performed in all patients and, where applicable, before and after therapy. Magnetic resonance was performed for evaluation of myocardial scar. Images were postprocessed and mechanical and electrical activation sequences were defined and time differences between the first and last ventricular segment to be activated were determined. Response to therapy was defined as a reduction in left ventricular end-systolic volume ≥ 15% after 12 months of follow-up.Results
Good correlation between electrical and mechanical timings was found in patients with normal left ventricular function (r2 = 0.88; P = .005) but not in those with left ventricular dysfunction (r2 = 0.02; P = not significant). After therapy, both timings and sequences were modified and improved, except in those with myocardial scar.Conclusions
Despite a close electromechanical relationship in normal left ventricular function, there is no significant correlation in patients with dysfunction. Although resynchronization therapy improves this correlation, the changes in electrical activation may not yield similar changes in left ventricular mechanics particularly depending on the underlying myocardial substrate.Full English text available from: www.revespcardiol.org\en 相似文献17.

Mortality from myocardial infarction is declining in high income countries, but the magnitude of this decline could differ between countries. We sought to compare the mortality trends from myocardial infarction between Spain and the United States.Methods
This was an observational retrospective study. Crude data were obtained from public databases. Standardized mortality rates were calculated for the last 17 years available for both countries (1990 to 2006), and stratified by age and sex. Joinpoint regression analysis was used for the trends analysis and projections.Results
There has been a steady decline in mortality from myocardial infarction in both countries from 1990 to 2006. However, the magnitude of this decline was greater in the United States (relative reductions in men: 42.7% [Spain] and 59.7% [United States], and in women: 40% [Spain] and 57.4% [United States]). The estimated annual percentages of decline in mortality were greater in the United States (men: −10.7%, women: −5.1%) than in Spain (men: −1.9%, women: −5.1%). Projections for 2012 suggest that the mortality from myocardial infarction will be lower in men in the United States (53.33/100 000) than in Spain (81.52/100 000), while for women it will be equal (32.56/100 000 in the United States and 33.56/100 000 in Spain).Conclusions
The decline in mortality from myocardial infarction has been more pronounced in the United States than in Spain, and projections for upcoming years suggest in the United States it will evolve to rates below those expected in Spain for men and equal rates for women.Full English text available from:www.revespcardiol.org 相似文献18.

Introduction
Clostridium difficile is responsible for a spectrum of diseases known as “Clostridium difficile infection” (CDI). It is currently the leading cause of nosocomial diarrhea in developed countries. This infection has been associated with both increased hospital stay and mortality, and to a greater likelihood of readmission. In our country these undesirable effects have not yet been characterized. Our objective was to quantify the increase in hospital stay attributable to infection by C. difficile.Methods
A retrospective cohort study matched by age, sex and admission date, was conducted in a tertiary care university hospital during an outbreak of nosocomial transmission of CDI.Results
The cohort study included 38 infected, and 76 non-infected patients. Patients who developed CDI showed a higher proportion of malnutrition at admission (OR = 10.3; 3.6 to 29.6), were exposed to a wider range of antibiotics (mean difference = 1.5; 0.7-2.2), had a higher mortality (31.6% vs. 6.6% of controls, P < .001), and a longer hospital stay (median 31.5 days versus 5.5 days for controls, P < .001). After adjustment, infection by C. difficile was associated with an increase in hospital stay of 4 days (P < .001).Conclusions
C. difficile infection has important consequences on the length of hospital stay, and therefore on health costs. 相似文献19.
Introduction and objectives
The Working Group on Cardiac Catheterization and Interventional Cardiology presents a yearly report on the data collected for the national registry. This information shows how procedures are distributed throughout Spain and makes comparisons with other countries feasible.Methods
Institutions provided their data voluntarily (online) and were analyzed by the Working Group's Steering Committee.Results
Data were provided by 108 hospitals (72 public and 36 private) that mainly treat adults, Covering 138 480 diagnostic procedures, 123 746 of which were coronary angiograms, slightly more than the year before, with a rate of 3008 coronary angiograms per million population. Percutaneous coronary interventions decreased slightly to 63 202 procedures with a rate of 1373 interventions per million population. Of the 94 701 stents implanted, 61% were drug-eluting stents. In the acute phase of myocardial infarction, 15 491 coronary interventions were performed, 9.4% more than in 2010, representing 24.6% of the total number of coronary interventions. The most frequent intervention for adult congenital heart disease was atrial septal defect closure (298 procedures). Percutaneous mitral valvuloplasty continued to decrease (286 procedures) and percutaneous aortic valve implantations increased, but at a slower pace than in the previous year, with 770 units implanted in 2011.Conclusions
The greatest increase in activity has occurred in the field of myocardial infarction and percutaneous aortic valve implantation. The number of other procedures, both diagnostic and therapeutic, remained stable.Full English text available from: www.revespcardiol.org 相似文献20.
