Abstract
OBJECTIVES Previous studies demonstrated women presenting with acute coronary syndrome (ACS) have poor outcomes when compared with men 'the gender gap phenomenon'. The impact of prior coronary artery bypass graft (CABG) on women presenting with ACS is unknown. We hypothesised that the gender gap is altered in ACS patients with prior CABG. The aim of this study was to evaluate patients presenting with ACS according to their gender and history of prior CABG. DESIGN Retrospective, observational (cohort) study. SETTING Data were collected from hospital-based registry of patients hospitalised with ACS in Doha, Qatar, from 1991 through 2010. The data were analysed according to their gender and history of prior CABG. PARTICIPANTS A total of 16 750 consecutive patients with ACS were studied. In total, 693 (4.3%) patients had prior CABG; among them 125 (18%) patients were women. PRIMARY AND SECONDARY OUTCOME MEASURES Comparisons of clinical characteristics, inhospital treatment, and outcomes, including inhospital mortality and stroke were made. RESULTS Women with or without prior CABG were older, less likely to be smokers, but more likely to have diabetes mellitus (DM), hypertension and renal impairment than men (p=0.001). Women were less likely to receive reperfusion and early invasive therapies. When compared with men, women without prior CABG carried higher inhospital mortality (11% vs 4.9%; p=0.001) and stroke rates (0.9% vs 0.3%; p=0.001). Female gender was independent predictor of poor outcome. Among prior CABG patients, despite the fact that women had worse baseline characteristics and were less likely to receive evidence-based therapy, there were no significant differences in mortality or stroke rates between the two groups. CONCLUSIONS Consistent with the world literature, women presenting with ACS and without prior CABG had higher death rates compared with men. Patients with prior CABG had comparable death rates regardless of the gender status.

Abstract
BACKGROUND The question of whether gender-related disparities still exist in the treatment and outcomes of patients presenting with acute coronary syndromes (ACS) remains controversial. Using data from 4 registries spanning a decade, we sought to determine whether sex-related differences have persisted over time and to examine the treating physician's rationale for adopting a conservative management strategy in women compared with men. METHODS From 1999 to 2008, 14,196 Canadian patients with non-ST-segment elevation ACS were recruited into the Acute Coronary Syndrome I (ACSI), ACSII, Global Registry of Acute Coronary Events (GRACE/GRACE(2)), and Canadian Registry of Acute Coronary Events (CANRACE) prospective multicenter registries. RESULTS Women in the study population were found to be significantly older than men and were more likely to have a history of heart failure, diabetes, or hypertension. Fewer women were treated with thienopyridines, heparin, and glycoprotein IIb/IIIa inhibitors compared with men in GRACE and CANRACE. Female gender was independently associated with a lower in-hospital use of coronary angiography (adjusted odds ratio 0.76, 95% CI 0.69-0.84, P < .001) and higher in-hospital mortality (adjusted odds ratio 1.26, 95% CI 1.02-1.56, P = .036), irrespective of age (P for interaction =.76). Underestimation of patient risk was the most common reason for not pursuing an invasive strategy in both men and women. CONCLUSIONS Despite temporal increases in the use of invasive cardiac procedures, women with ACS are still more likely to be treated conservatively, which may be due to underestimation of patient risk. Furthermore, they have worse in-hospital outcomes. Greater awareness of this paradox may assist in bridging the gap between current guidelines and management practices.

Abstract
OBJECTIVE In ST elevation myocardial infarction women received less evidence-based medicine and had worse outcome during the fibrinolytic era. With the shift to primary percutaneous coronary intervention (pPCI) as preferred reperfusion strategy, the authors aimed to investigate whether these gender differences has diminished. DESIGN, SETTING AND PARTICIPANTS Cohort study including consecutive ST elevation myocardial infarction patients registered 1998-2000 (n=15 697) and 2004-2006 (n=14 380) in the Register of Information and Knowledge about Swedish Heart Intensive care Admissions. OUTCOME MEASURES 1. Use of evidence-based medicine such as reperfusion therapy (pPCI or fibrinolysis) and evidence-based drugs at discharge. 2. Inhospital and 1-year mortality. RESULTS Of those who got reperfusion therapy, pPCI was the choice in 9% in the early period compared with 68% in the late period. In the early period, reperfusion therapy was given to 63% of women versus 71% of men, p<0.001. Corresponding figures in the late period were 64% vs 75%, p<0.001. After multivariable adjustments, the ORs (women vs men) were 0.86 (95% CI 0.78 to 0.94) in the early and 0.80 (95% CI 0.73 to 0.89) in the late period. As regards evidence-based secondary preventive drugs at discharge in hospital survivors (platelet inhibitors, statins, ACE inhibitors/angiotensin receptor blockers and β-blockers), there were small gender differences in the early period. In the late period, women had 14%-25% less chance of receiving these drugs, OR 0.75 (95% CI 0.68 to 0.81) through 0.86 (95% CI 0.73 to 1.00). In both periods, multivariable-adjusted inhospital mortality was higher in women, OR 1.18 (95% CI 1.02 to 1.36) and 1.21 (1.00 to 1.46). One-year mortality was gender equal, HR 0.95 (95% CI 0.87 to 1.05) and 0.96 (0.86 to 1.08), after adding evidence-based medicine to the multivariable adjustments. CONCLUSION In spite of an intense gender debate, focus on guideline adherence and the change in reperfusion strategy, the last decade gender differences in use of reperfusion therapy and evidence-based therapy at discharge did not decline during the study period, rather the opposite. Moreover, higher mortality in women persisted.

Abstract
Accurate and readily available systems for risk stratification and a wide array of antithrombotic agents, on top of classical anti-ischemic drugs, provide the noninvasive cardiologist admitting the patient in the CCU with an effective and reliable armamentarium for the safe management of most patients with ACS. From the interventionalist's perspective, the immediate knowledge of the coronary anatomy yields the most valuable information to address the most appropriate treatment. The sooner angiography is performed the higher the benefit for patients at moderate to high risk, but if performed by expert teams and with the correct use of modern drugs and devices, the invasive approach has the potential to reduce costs and length of hospital stay also in low-risk patients. Although still some reluctance remains to equalize treatment strategies for patients with STEMI to those with NSTEMI, such differences will likely disappear in the near future with upcoming new evidence. Cardiac surgery may represent a life-saving alternative for patients presenting with NSTEMI evolving in cardiogenic shock or with mechanical complications, or in patients unsuitable for PCI or with failed PCI attempts. In stabilized conditions after the treatment of the culprit lesion, patients with severe multivessel disease may benefit from cardiac surgery to complete myocardial revascularization. Indications for CABG in this setting should be evaluated in the context of a local "heart team" or through prespecified protocols in centers without cardiac surgery on site.

Abstract
BACKGROUND There is conflicting evidence regarding sex-based differences in myocardial salvage and clinical outcome in patients after ST-elevation myocardial infarction (STEMI). The aim of this study was to investigate whether there are sex-associated differences in infarct characteristics (myocardial salvage, infarct size, microvascular obstruction) and clinical outcome in STEMI patients who are reperfused by primary angioplasty. METHODS AND RESULTS In this study, we included 96 women and 239 men with STEMI undergoing primary angioplasty <12 hours after symptom onset. T2-weighted and contrast-enhanced cardiac MRI was used to assess myocardial salvage, infarct size, and microvascular obstruction. The primary clinical end point was mortality within 6 months after the index event. The amount of myocardium at risk and final infarct size did not differ significantly between women and men. Consequently, myocardial salvage was similar between groups (P=0.36). Women had a higher in-hospital (3% versus 10%; P=0.03) and 30-day (5% versus 11%; P=0.05) mortality rate than did men. Six months after infarction, no significant sex differences in survival were obvious (11% versus 7%; P=0.21). After adjustment for baseline differences (age, diabetes, hypertension), female sex was not an independent predictor of mortality and major adverse cardiac events. CONCLUSIONS The efficacy of primary percutaneous coronary intervention (myocardial salvage) in patients with STEMI is not sex dependent. Although women STEMI patients had worse unadjusted in-hospital and 30-day clinical outcomes than did men, multivariate analysis revealed that the observed sex-based differences in early death after STEMI were likely related to differences in baseline risk and clinical characteristics.

Abstract
Coronary disease is a major cause of death and disability. From 1975 to 2000, coronary mortality was reduced by half. Better treatments and reduction of risk factors are the main causes. This phenomenon is observed in most developed countries, but mortality from coronary heart disease continues to increase in developing countries. In-hospital mortality of ST elevation myocardial infarction (STEMI) is in the range of 7 to 10% in registries. In infarction without ST segment elevation (NSTEMI), in-hospital mortality is around 5%. More recent studies found a similar in-hospital mortality for STEMI and NSTEMI. Because of patient selection and monitoring, mortality in clinical trials is much lower. After adjustment for the extent of coronary disease, age, risk factors, history of myocardial infarction, the excess mortality observed in women is fading. Many clinical, biological and laboratory parameters are associated with mortality in myocardial infarction. They refer to the immediate risk of death (ventricular rhythm disturbances, shock…), the extent of infarction (number of leads with ST elevation on the ECG, release of biomarkers, ejection fraction…), the presence of heart failure, the failure of reperfusion and the patient's baseline risk (age, renal function…). Risk scores, and more specifically the GRACE risk score, synthesize these different markers to predict the risk of death in a given patient. However, their use for the treatment of myocardial only concerns NSTEMI. Only a limited number of mechanical or pharmacological interventions reduces mortality of heart attack. The main benefits are observed with reperfusion by thrombolysis or primary angioplasty in STEMI, aspirin, heparin, beta-blockers, angiotensin converting enzyme inhibitors. Some medications such as bivalirudin and fondaparinux reduce mortality by decreasing the incidence of hemorrhagic complications. The guidelines classify interventions according to their benefit and especially their ability to reduce mortality. Organized care systems that improve implementation of guidelines also reduce mortality. Finally, some new therapeutic approaches such as post-conditioning and new therapeutic classes offer encouraging prospects for further reducing the mortality of myocardial infarction.

Abstract
BACKGROUND The Myocardial Infarction Network Essen was initiated in order to establish a standardized procedure with immediate reopening of the infarcted vessel for patients with ST-elevation myocardial infarction (STEMI) in the city of Essen, Germany. The present study aims to evaluate gender-related differences in presentation of disease and clinical outcome. HYPOTHESIS Gender is associated with differences in presentation and outcome of STEMI. METHODS All patients with STEMI were included without exception. Parameters such as risk profile, mortality, and relevant time intervals were documented. The follow-up period was 1 year. RESULTS For this study, 1365 patients (72.1% male) were recruited. Women were significantly older, with higher prevalence of diabetes (28.1% vs 20.3%, P = 0.004) and hypertension (76.5% vs 64.8%, P<0.0005). Analysis of time intervals between symptoms to actions showed no significant differences. However, women tended to wait longer before calling for medical assistance (358 vs 331 min, P = 0.091). In-hospital mortality was comparable with respect to gender, whereas women had higher 1-year mortality (18.6% vs 13.2%). Age and diabetes were associated with a higher mortality. Adjusted for age, gender is no longer an independent risk factor. In the follow-up period, significantly more women were readmitted to the hospital without a difference in the frequency of reangiography, surgery, or target-vessel revascularization. CONCLUSIONS The present data display a successful implementation of a standardized procedure in patients with STEMI. Although differences between genders are not as obvious as expected, efforts should be taken to perform a gender-specific risk analysis as well as to promote education about proper behavior in case of new onset of angina.

Abstract
The greater mortality observed in women compared to men after acute myocardial infarction remains unexplained. Using an analysis of pairs, matched on a conditional probability of being male (propensity score), we assessed the effect of the baseline characteristics and management on 30-day mortality. Consecutive patients were included from January 2006 to December 2007. Two propensity scores (for being male) were calculated, 1 from the baseline characteristics and 1 from both the baseline characteristics and treatment. Two matched cohorts were composed using 1:1 matching and computed using the best 8 digits of the propensity score. Paired analyses were performed using conditional regression analysis. During the study period, 3,510 patients were included in the registry; 1,119 (32%) were women. Compared to the men, the women were 10 years older, had more co-morbidities, less often underwent angiography and reperfusion, and received less medical treatment. The 30-day mortality rate was 12.3% (130 of 1,060) for the women and 7.2% (167 of 2,324) for the men (p <0.001). The 2 matched populations represented 1,298 and 1,168 patients. After matching using the baseline characteristics, the only difference in treatment was a lower rate of angiography and reperfusion, with a trend toward greater 30-day mortality in women. After matching using both baseline characteristics and treatment, the 30-day mortality was similar for the men and women, suggesting that the increased use of invasive procedures in women could potentially be beneficial. In conclusion, compared to men, the 30-day mortality is greater in women and explained primarily by differences in baseline characteristics and to a lesser degree by differences in management. The difference in the use of invasive procedures persisted after matching by characteristics. In contrast, after matching using the baseline characteristics and treatment, the 30-day mortality was comparable across the genders.

Abstract
BACKGROUND There is no angiographically demonstrable obstructive coronary artery disease (CAD) in a significant minority of patients with myocardial infarction, particularly women. We sought to determine the mechanism(s) of myocardial infarction in this setting using multiple imaging techniques. METHODS AND RESULTS Women with myocardial infarction were enrolled prospectively, before angiography, if possible. Women with ≥50% angiographic stenosis or use of vasospastic agents were excluded. Intravascular ultrasound was performed during angiography; cardiac magnetic resonance imaging was performed within 1 week. Fifty women (age, 57±13 years) had median peak troponin of 1.60 ng/mL; 11 had ST-segment elevation. Median diameter stenosis of the worst lesion was 20% by angiography; 15 patients (30%) had normal angiograms. Plaque disruption was observed in 16 of 42 patients (38%) undergoing intravascular ultrasound. There were abnormal myocardial cardiac magnetic resonance imaging findings in 26 of 44 patients (59%) undergoing cardiac magnetic resonance imaging, late gadolinium enhancement (LGE) in 17 patients, and T2 signal hyperintensity indicating edema in 9 additional patients. The most common LGE pattern was ischemic (transmural/subendocardial). Nonischemic LGE patterns (midmyocardial/subepicardial) were also observed. Although LGE was infrequent with plaque disruption, T2 signal hyperintensity was common with plaque disruption. CONCLUSIONS Plaque rupture and ulceration are common in women with myocardial infarction without angiographically demonstrable obstructive coronary artery disease. In addition, LGE is common in this cohort of women, with an ischemic pattern of injury most evident. Vasospasm and embolism are possible mechanisms of ischemic LGE without plaque disruption. Intravascular ultrasound and cardiac magnetic resonance imaging provide complementary mechanistic insights into female myocardial infarction patients without obstructive coronary artery disease and may be useful in identifying potential causes and therapies.

Abstract
OBJECTIVE To investigate possible gender differences in patients with acute myocardial infarction (AMI) and without significant stenoses on coronary angiography (CAG) regarding prognosis and use of secondary preventive medication. DESIGN Nationwide register-based cohort study. PATIENTS By compiling data from Danish registries, we identified 20,800 patients hospitalized with AMI during 2005-2007. We included the 834 women and 761 men without significant stenoses on CAG who were discharged and alive after 60 days. MAIN OUTCOME MEASURES All-cause mortality, recurrent AMI, and redeeming a prescription for a lipid-lowering drug, beta-blocker, clopidogrel, or aspirin within 60 days of discharge. RESULTS During follow-up, 97 women and 60 men died, resulting in a crude female/male hazard ratio (HR) of 1.51 (95% CI 1.09-2.08). After adjustment for age, time-period, and comorbidity, the gender difference was attenuated (HR 1.22, 95% CI 0.86-1.72). AMI recurrence was experienced by 28 women and 29 men with a female/male HR 0.88 (95% CI 0.52-1.48). After multivariable adjustment results were similar (HR 0.84, 95% CI 0.50-1.43). More women than men redeemed a prescription for lipid-lowering drugs with no differences in other medication. In the adjusted models lipid-lowering drugs, beta-blockers, clopidogrel, and aspirin were all redeemed equally with odds ratio (OR) 1.25 (95% CI 0.99-1.59), OR 1.10 (95% CI 0.88-1.37), OR 1.09 (95% CI 0.88-1.34), and OR 1.13 (95% CI 0.90-1.42), respectively. CONCLUSION Our study shows that in a population of patients with a first admission for AMI and no significant stenoses on CAG, women share the same prospects as men regarding long-term prognosis and the extent of secondary preventive medical treatment.

Abstract
Declining trends in case fatality (CF) of MI events have been generally reported in western countries. It is, however, not clear whether the development has been equally beneficial in both sexes. Data from two large population based registers, FINAMI and the Finnish National Cardiovascular Disease Register (CVDR) were used to determine whether the CF of incident MI events has declined less in women than in men. All patients aged 35 and over were included. CF was calculated for different time periods after the onset of the MI event, the main emphasis was in pre-hospital, 28-day, and 1-year CF. Figures were compared between two study periods: 1994-1996 and 2000-2002. A total of 6,342 incident MI events were recorded in FINAMI and 117,632 events in CVDR during the study periods. Comparison between the two study periods showed that the CF was generally declining. However, a slower decline in short-term CF was seen among young (aged<55 years) women (P for sex by study period interaction in pre-hospital CF=0.028 in FINAMI and 0.003 in CVDR, and for 28-day CF P=0.016 in FINAMI and <0.0001 in CVDR). In conclusion, the short and long-term prognosis of MI events has improved in both sexes. Pre-hospital CF has declined less among younger women than among men and among older women. This slower decline in early CF was responsible for the slower improvement in 28-day and 1-year prognosis in young women.

Abstract
BACKGROUND/OBJECTIVES To describe the evolution of the therapeutic practices over 10 years of follow-up of acute myocardial infarction (AMI) in Charleroi and to analyse the factors influencing the choice of treatments and the mortality of these patients. METHODS The Charleroi register of ischaemic cardiopathies is the oldest register of infarctions in the French-speaking community of Belgium and is one of the very rare registers that allows identifying tendencies over 25 years. Analyses presented hereafter relate only patients in the 25-69-year age range over time from 1998 to 2007. The data were analysed in five periods of 2 years. Treatment evolutions over time were analysed using chi-squared tests for trend and logistic regression analyses identify factors influencing the type of treatment. RESULTS The present study shows a marked increase in the utilization of percutaneous transluminal coronary angioplasty (PTCA) between 1998-1999 and 2006-2007. The use of thrombolytic agents on approximately one-third of the patients treated remained fairly stable between 1998 and 2007. A lower proportion of patients with a history of AMI received thrombolytic agents. Thrombolysis seems beneficial for men and without effect for women. The use of β-blockers continued to increase until the 2000-2001 period and remained fairly stable for the two following periods. 42% of patients were administered three medications (angiotensin-converting enzyme inhibitors, antiplatelet drugs, and β-blockers). Association of PTCA with antiplatelet drugs, β-blockers, and thrombolysis was observed for 58.7, 50.6, and 25.7%, respectively. These associations were still observed after adjustment for gender, age, and comorbidity. The factors associated with fatality were specifically old-aged patients, antecedents of diabetes, hypercholesterolaemia and oral antiplatelet drugs, and β-blockers therapies and PTCA. CONCLUSIONS The evolution of the therapeutic data on AMI in this register confirms the use and the efficacy of thrombolytic therapy. PTCA becomes the main coronary reperfusion treatment with less risk of bleeding. Angiotensin-converting enzyme inhibitors were without effect on mortality.

Abstract
Ischemic heart disease (IHD) is a leading cause of morbidity in the United States and worldwide. In women, it is the leading cause of death in all age groups except young women who rarely have clinically evident disease. However, when young women less than age 50 develop IHD, they are at high risk for mortality. This may be due in part to delay in diagnosis or less aggressive treatment. Young women may be less aggressively treated with medical therapies and percutaneous or surgical interventions despite studies that have shown benefit in women as well as men. Young women are an especially important population to target for treatment and study since prevention of IHD during this stage of life can have great personal and societal health consequences. Epidemiological studies, including the INTERHEART study, have identified risk factors including hypertension, diabetes, metabolic syndrome, smoking, and sedentary lifestyle that explain much of IHD in women. Several factors, including diabetes, metabolic syndrome, and tobacco use, are stronger predictors of IHD in young women as compared with older women. Healthcare practitioners who encounter young women should aggressively treat risk factors, maintain an appropriate index of suspicion for IHD, and treat acute coronary syndromes promptly and intensively to reduce the burden of IHD in young women.

Abstract
Women who present with coronary artery disease have different characteristics, undergo different treatment, and have a different prognosis than men. The increasing use of coronary stenting has improved the outcome of percutaneous coronary intervention (PCI). However, little is known about the outcomes for men versus women after PCI, especially for those presenting with a diagnosis of acute coronary syndrome. Thus, we compared the baseline features, management, and long-term outlook of men versus women undergoing PCI. All consecutive patients who had undergone PCI with stents at our center from July 1, 2002 to June 30, 2004 were identified retrospectively. The primary end point was the long-term rate of major adverse cardiac events (i.e., death, infarction, and repeat revascularization). The secondary end points were the individual components of the major adverse cardiac events and stent thrombosis. A total of 833 patients were included, 210 women (25.2%) and 623 men (75.8%). The women were significantly older (70.9 vs 63 years, p <0.001) and more often had diabetes mellitus (36.2% vs 21.0%, p <0.001) and hypertension (82.3% vs 73.7%, p = 0.006). The number of drug-eluting stents and the length were significantly lower in the female patients. The incidence of major adverse cardiac events after a median follow-up of 60 months was similar for both women and men (38.8% vs 46.4%, p = 0.075), with a trend toward greater mortality rate for women (21.2% vs 15.4%, p = 0.090). All other end points occurred with similar frequencies. Only in the subgroup of ST-segment elevation myocardial infarction were the rates of death significantly greater for the women than for the men (20.0% vs 8.1%; p = 0.029). In conclusion, very long-term follow-up of women undergoing PCI with coronary artery stenting resulted in similar rates of cardiac event compared to those of men, but greater care should be given to women presenting with ST-segment elevation myocardial infarction. Also, despite their greater baseline risk profile, women were significantly less likely to have received effective treatment, the use of including drug-eluting stents.

Abstract
Each year, the American Heart Association (AHA), in conjunction with the Centers for Disease Control and Prevention, the National Institutes of Health, and other government agencies, brings together the most up-to-date statistics on heart disease, stroke, other vascular diseases, and their risk factors and presents them in its Heart Disease and Stroke Statistical Update. The Statistical Update is a valuable resource for researchers, clinicians, healthcare policy makers, media professionals, the lay public, and many others who seek the best national data available on disease morbidity and mortality and the risks, quality of care, medical procedures and operations, and costs associated with the management of these diseases in a single document. Indeed, since 1999, the Statistical Update has been cited more than 8700 times in the literature (including citations of all annual versions). In 2009 alone, the various Statistical Updates were cited ≈1600 times (data from ISI Web of Science). In recent years, the Statistical Update has undergone some major changes with the addition of new chapters and major updates across multiple areas. For this year’s edition, the Statistics Committee, which produces the document for the AHA, updated all of the current chapters with the most recent nationally representative data and inclusion of relevant articles from the literature over the past year and added a new chapter detailing how family history and genetics play a role in cardiovascular disease (CVD) risk. Also, the 2011 Statistical Update is a major source for monitoring both cardiovascular health and disease in the population, with a focus on progress toward achievement of the AHA’s 2020 Impact Goals. Below are a few highlights from this year’s Update.

Abstract
OBJECTIVE Gender differences in the clinical presentation and management of patients with acute coronary syndrome (ACS) have been reported in different parts of the world with contradicting results. We aimed at investigating the presence of gender bias in patients admitted with ACS to Aseer Central Hospital (ACH). METHODS A retrospective cohort of all consecutive patients admitted to ACH with the diagnosis of ACS, during the period between the 1st of June 2007 and the 31st of May 2009 was studied. Data on demographic and clinical profiles, management and outcomes of ACS patients were collected and compared for both genders. RESULTS The present study included 148 females and 397 males. Females were significantly older than males (62.9 ± 14.2 vs. 60 ± 13.4, respectively, P < 0.03), were less likely ever to have smoked (0.7% vs. 26.2%, respectively, P < 0.001), less likely to have had a history of hyperlipidemia (10.8% vs. 22.2%, respectively, P < 0.003) or family history of ischemic heart disease (10.1% vs. 18.9%, respectively, P < 0.014). Female patients presented more with atypical presentation (42.6% vs. 28.9%, respectively, P < 0.003), more with unstable angina (72.3% vs. 50.4%, respectively, P < 0.001), and less with ST-elevation myocardial infarction (18.9% vs. 40.8%, respectively, P < 0.001). Furthermore, they had significantly lower levels of hemoglobin compared to males (12.9 ± 2.3 vs. 14.5 ± 2.2 g/L, respectively, P < 0.001), and higher levels of high density lipoprotein (1.1 ± 0.4 vs. 0.98 ± 0.4 mmol/L, respectively, P < 0.008). Left ventricular ejection fraction was significantly higher in female patients compared to males (50.9 ± 14 vs. 45.8 ± 14, respectively, P < 0.003). Coronary angiography showed a higher rate of normal findings (29.3% vs. 8.9%, respectively, P < 0.001) and less severe disease (46.7% vs. 60.3%, respectively, P < 0.027) in women, however, they were less likely to undergo invasive revascularization procedures (31% vs. 42.8%, respectively, P < 0.013). No significant differences were found between both sexes regarding in-hospital mortality or re-infarction rates. CONCLUSION We documented gender differences in both clinical presentation as well as management of patients admitted with ACS to ACH. However, there were no significant differences between both genders regarding the clinical in-hospital outcomes. Emphasis should be made to avoid such bias in the future.

Abstract
OBJECTIVE To assess the sex difference in hospital mortality following ST elevation myocardial infarction (STEMI) in China. DESIGN Observational study of patients enrolled into a large trial, adjusting for age, presenting characteristics and hospital treatments using logistic regression. SETTINGS 1250 hospitals in China during 1999-2005. PATIENTS 42 683 STEMI patients, including 31 309 men and 11 374 women. INTERVENTION In the original trial, all patients received 162 mg of aspirin plus 75 mg of clopidogrel daily or matching placebo and metoprolol (15 mg intravenous then 200 mg oral daily) or matching placebo. All other aspects of patients' treatments were at the discretion of responsible doctors. MAJOR OUTCOMES Hospital mortality from any cause during the scheduled trial treatment period (ie, up to 4 weeks in hospital). RESULTS Overall, 8% of the patients died in hospital, with the crude hospital mortality being twice as high in women as in men (12.6% vs 6.3%). After adjusting for age, the sex difference in hospital mortality attenuated but remained highly significant (OR 1.54; 95% CI 1.43 to 1.66). Further adjustment for other baseline characteristics and for the treatments given in hospital had little effect on the sex difference in hospital mortality (OR 1.50, 95% CI 1.38 to 1.62). The difference in hospital mortality was greater at a younger age, with the adjusted ORs being 2.14, 1.70, 1.48 and 1.18, respectively, for ages <55, 55-64, 65-74 and ≥75 years (p=0.0001 for trend). CONCLUSION Compared with men of the same age, women had approximately a 50% higher mortality following hospital admission for STEMI, with a particularly higher excess risk at age <55 years.

Abstract
BACKGROUND historically, women with ST elevation myocardial infarction (STEMI) have had a higher mortality compared with men. It is unclear if these differences persist among patients undergoing contemporary primary percutaneous coronary intervention (PCI) with focus on early reperfusion. METHODS we assessed the impact of sex on the outcome of 8,771 patients with acute STEMI who underwent primary PCI from 2003 to 2008 at 32 hospitals participating in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium PCI registry. A propensity-matched analysis was performed to adjust for differences in baseline characteristics and comorbidities between men and women. RESULTS twenty-nine percent of the cohort was female. Compared with men, women were older and had more comorbidity. Female sex was associated with a higher unadjusted in-hospital mortality (6.02% vs 3.45%, odds ratio [OR] 1.79, 95% CI 1.45-2.22, P < .0001) and higher risk of contrast-induced nephropathy (OR 1.75, P < .0001), vascular complications (OR 2.13, P < .0001), and postprocedure transfusion (OR 2.84, P < .0001). The gap in sex-specific mortality narrowed over time. In a propensity-matched analysis, female sex was associated with a higher rate of transfusion (OR 1.88, 95% CI 1.57-2.24, P < .0001) and vascular complications (OR 1.65, 95% CI 1.26-2.14, P < .0002); but there was no difference in mortality (OR 1.30, 95% CI 0.98-1.72, P = .07). CONCLUSIONS women make up approximately one third of patients undergoing primary PCI for STEMI. Female sex is associated with an apparent hazard of increased mortality among patients undergoing primary PCI for STEMI, but this difference is likely explained by older age and worse baseline comorbidities among women.

Abstract
Cardiovascular disease (CVD) is the leading cause of death in women, and knowledge of the clinical consequences of atherosclerosis and CVD in women has grown tremendously over the past 20 years. Research efforts have increased and many reports on various aspects of ischaemic heart disease (IHD) in women have been published highlighting sex differences in pathophysiology, presentation, and treatment of IHD. Data, however, remain limited. A description of the state of the science, with recognition of the shortcomings of current data, is necessary to guide future research and move the field forward. In this report, we identify gaps in existing literature and make recommendations for future research. Women largely share similar cardiovascular risk factors for IHD with men; however, women with suspected or confirmed IHD have less coronary atherosclerosis than men, even though they are older and have more cardiovascular risk factors than men. Coronary endothelial dysfunction and microvascular disease have been proposed as important determinants in the aetiology and prognosis of IHD in women, but research is limited on whether sex differences in these mechanisms truly exist. Differences in the epidemiology of IHD between women and men remain largely unexplained, as we are still unable to explain why women are protected towards IHD until older age compared with men. Eventually, a better understanding of these processes and mechanisms may improve the prevention and the clinical management of IHD in women.

Abstract
OBJECTIVE To assess gender-related differences in the presentation, management, and in-hospital outcomes among acute coronary syndrome (ACS) patients from Oman. METHODS Data were analyzed from 1579 consecutive ACS patients from Oman during May 8, 2006 to June 6, 2006 and January 29, 2007 to June 29, 2007, as part of Gulf RACE (Registry of Acute Coronary Events). Analyses were conducted using univariate and multivariate statistical techniques. RESULTS In this study, 608 (39%) patients were women with mean age 62 ± 12 vs. 57 ± 13 years (p < 0.001). More women were seen in the older age groups (age <55 years: 25% vs. 43%, 55-74 years: 60% vs. 49% and >75 years: 15% vs. 8%; p < 0.001). Women had higher frequencies of diabetes, hypertension, hyperlipidemia, obesity, angina, and aspirin use, but less history of smoking. Women were significantly less likely to have ischemic chest pain, ST-elevation myocardial infarction (STEMI), non-STEMI and were more likely to have dyspnea, unstable angina, ST depression and left bundle branch block. Both groups received ACS medications and cardiac catheterization equally; however, women received anticoagulants (88% vs. 79%; p < 0.001), angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) (70% vs. 65%; p = 0.050) more and clopidogrel less (20% vs. 29%; p < 0.001). Women experienced more recurrent ischemia and heart failure but with similar in-hospital mortality (4.6% vs. 4.3%) even after adjusting for age (p = 0.500). CONCLUSIONS Women admitted with ACS were older than men, had more risk factors, presented differently with no difference in hospital mortality. This is similar to Gulf RACE study except for mortality. Women received anticoagulants/ACEIs /ARBs more but were under-treated with clopidogrel.

Abstract
Chest pain is one of the most common symptoms driving patients to a physician's office or the hospital's emergency department. In approximately half of the cases, chest pain is of cardiac origin, either ischemic cardiac or nonischemic cardiac disease. The other half is due to noncardiac causes, primarily esophageal disorder. Pain from either origin may occur in the same patient. In addition, psychological and psychiatric factors play a significant role in the perception and severity of the chest pain, irrespective of its cause. Chest pain of ischemic cardiac disease is called angina pectoris. Stable angina may be the prelude of ischemic cardiac disease; and for this reason, it is essential to ensure a correct diagnosis. In most cases, further testing, such as exercise testing and angiography, should be considered. The more severe form of chest pain, unstable angina, also requires a firm diagnosis because it indicates severe coronary disease and is the earliest manifestation of acute myocardial infarction. Once a diagnosis of stable or unstable angina is established, and if a decision is made not to use invasive therapy, such as coronary bypass, percutaneous transluminal coronary angioplasty, or stent insertion, effective medical treatment of associated cardiac risk factors is a must. Acute myocardial infarction occurring after a diagnosis of angina greatly increases the risk of subsequent death. Chest pain in women warrants added attention because women underestimate their likelihood to have coronary heart disease. A factor that complicates the clinical assessment of patients with chest pain (both cardiac and noncardiac in origin) is the relatively common presence of psychological and psychiatric conditions such as depression or panic disorder. These factors have been found to cause or worsen chest pain; but unfortunately, they may not be easily detected. Noncardiac chest pain represents the remaining half of all cases of chest pain. Although there are a number of causes, gastroesophageal disorders are by far the most prevalent, especially gastroesophageal reflux disease. Fortunately, this disease can be diagnosed and treated effectively by proton-pump inhibitors. The other types of non-gastroesophageal reflux disease-related noncardiac chest pain are more difficult to diagnose and treat. In conclusion, the cause of chest pain must be accurately diagnosed; and treatment must be pursued according to the cause, especially if the cause is of cardiac origin.

Abstract
Female mammals have long been neglected in biomedical research. The NIH mandated enrollment of women in human clinical trials in 1993, but no similar initiatives exist to foster research on female animals. We reviewed sex bias in research on mammals in 10 biological fields for 2009 and their historical precedents. Male bias was evident in 8 disciplines and most prominent in neuroscience, with single-sex studies of male animals outnumbering those of females 5.5 to 1. In the past half-century, male bias in non-human studies has increased while declining in human studies. Studies of both sexes frequently fail to analyze results by sex. Underrepresentation of females in animal models of disease is also commonplace, and our understanding of female biology is compromised by these deficiencies. The majority of articles in several journals are conducted on rats and mice to the exclusion of other useful animal models. The belief that non-human female mammals are intrinsically more variable than males and too troublesome for routine inclusion in research protocols is without foundation. We recommend that when only one sex is studied, this should be indicated in article titles, and that funding agencies favor proposals that investigate both sexes and analyze data by sex.

Abstract
BACKGROUND To analyze the in-hospital complication rate in women suffering from non-ST elevation myocardial infarction treated with percutaneous coronary intervention (PCI) compared to men. METHODS The files of 479 consecutive patients (133 women and 346 men) suffering from a Non STEMI (Non ST-segment elevation myocardial infarction) between the January 1st 2006 and March 21st 2009 were retrospectively analyzed with special attention to every single complication occurring during hospital stay. Data were analyzed using nonparametric tests and are reported as median unless otherwise specified. A p value < .05 was considered significant. RESULTS As compared to men, women were significantly older (75.8 vs. 65.2 years; p < .005). All cardiovascular risk factors but tobacco and hypertension were similar between the groups: men were noticeably more often smoker (p < .0001) and women more hypertensive (p < .005). No difference was noticed for pre-hospital cardiovascular drug treatment. However women were slightly more severe at entry (more Killip class IV; p = .0023; higher GRACE score for in-hospital death - p = .008 and CRUSADE score for bleeding - p < .0001). All the patients underwent PCI of the infarct-related artery after 24 or 48 hrs post admission without sex-related difference either for timing of PCI or primary success rate. During hospitalization, 130 complications were recorded. Though the event rate was slightly higher in women (30% vs. 26% - p = NS), no single event was significantly gender related. The logistic regression identified age and CRP concentration as the only predictive variables in the whole group. After splitting for genders, these parameters were still predictive of events in men. In women however, CRP was the only one with a borderline p value. CONCLUSIONS Our study does not support any gender difference for in-hospital adverse events in patients treated invasively for an acute coronary syndrome without ST-segment elevation and elevated troponin.

Abstract
BACKGROUND Awareness of cardiovascular disease (CVD) risk has been linked to taking preventive action in women. The purpose of this study was to assess contemporary awareness of CVD risk and barriers to prevention in a nationally representative sample of women and to evaluate trends since 1997 from similar triennial surveys. METHODS AND RESULTS A standardized survey about awareness of CVD risk was completed in 2009 by 1142 women >or=25 years of age, contacted through random digit dialing oversampled for racial/ethnic minorities, and by 1158 women contacted online. There was a significant increase in the proportion of women aware that CVD is the leading cause of death since 1997 (P for trend=<0.0001). Awareness among telephone participants was greater in 2009 compared with 1997 (54% versus 30%, P<0.0001) but not different from 2006 (57%). In multivariate analysis, African American and Hispanic women were significantly less aware than white women, although the gap has narrowed since 1997. Only 53% of women said they would call 9-1-1 if they thought they were having symptoms of a heart attack. The majority of women cited therapies to prevent CVD that are not evidence-based. Common barriers to prevention were family/caretaking responsibilities (51%) and confusion in the media (42%). Community-level changes women thought would be helpful were access to healthy foods (91%), public recreation facilities (80%), and nutrition information in restaurants (79%). CONCLUSIONS Awareness of CVD as the leading cause of death among women has nearly doubled since 1997 but is stabilizing and continues to lag in racial/ethnic minorities. Numerous misperceptions and barriers to prevention persist and women strongly favored environmental approaches to facilitate preventive action.

Abstract
BACKGROUND Women with non-ST-segment elevation myocardial infarction (NSTEMI) who undergo coronary angiography have no obstructive coronary lesions more often than men. Sex-specific characteristics and outcomes of patients without obstructive coronary artery disease (CAD) have not been described previously. METHODS Using data from NSTEMI patients enrolled in CRUSADE from 2001 to 2005, we evaluated differences in clinical features and in-hospital outcomes between men and women with no obstructive CAD. RESULTS After excluding patients with missing catheterization and sex data (n = 1,494), previous coronary artery bypass grafting or percutaneous coronary intervention (47,907), catheterization contraindications (n = 6,588), and missing obstructive CAD status (n = 1,565), there were 55,514 patients (68.4%) with NSTE acute coronary syndromes (ACS) who underwent angiography (among women, 62.1% [21,294/34,290], and among men, 73% [34,220/46,875]; P < .001). Among these, a total of 5,538 patients (10.0%) had nonnonobstructive CAD-15.1% (3,221/21,294) of women and 6.8% (2,317/34,220) of men (P < .0001). In patients without obstructive CAD, women were as likely as men to have MI (troponin elevation in 89% vs 87%, P = .37). Women and men were equally likely to have larger troponin elevations (58.9% vs 58.6% with troponin >5x upper limit of normal, P = .69, respectively). In NSTEMI patients without obstructive CAD, in-hospital death (0.6% women vs 0.7% men) and cardiogenic shock (1.0% women vs 0.7% men) were infrequent. CONCLUSIONS Among NSTE ACS patients undergoing coronary angiography, absence of obstructive CAD is more common in women than men. Although nonobstructive CAD was twice as common among women with NSTEMI, sex differences in characteristics and outcomes were similar to those found with obstructive CAD. Unadjusted in-hospital outcomes of NSTEMI patients with nonobstructive CAD are favorable in both sexes. Whether the underlying pathophysiology of NSTE ACS without documentation of obstructive CAD is different between women and men requires further study.
