Abstract
Objective Prognostic indicators in acute coronary syndrome (ACS) would aid in decision-making and identifying high-risk patients. The systemic immune-inflammation index (SII) has good prognostic value in many diseases; however, its use has not been reported for ACS. We aimed to determine the associations between the SII and outcomes in patients with ACS, with adjustment for confounders. Methods In this retrospective cohort study, we used the MIMIC-III (Multiparameter Intelligent Monitoring in Intensive Care) database and the eICU Collaborative Research Database. The primary outcome was 30-day mortality. Cox regression analysis was performed to determine the relationship between the SII and patient outcomes, and we conducted subgroup analysis and smooth curve fitting. Results We identified 4699 patients with ACS: 1741 women and 2949 men, mean age 82.8±29.7 years, and mean SII 72.58±12.9. For 30-day all-cause mortality, the unadjusted hazard ratio (HR) (95% confidence interval [CI]) of SII <69.4 and SII >88.8 were 1.25 (1.04, 1.50) and 1.38 (1.15, 1.65), respectively. With SII >88.8, this association remained significant after adjustment for numerous potential confounders: HR 1.27 (1.06, 1.52). A similar relationship was observed for 90-day and 1-year all-cause mortality. Conclusions SII is a promising prognostic indicator for unselected patients with ACS. This finding needs to be confirmed in prospective studies.

Abstract
BACKGROUND AND OBJECTIVES Previous researches have reported the controversial results regarding the gender difference in clinical outcomes of patients with coronary artery disease after percutaneous coronary intervention. Hence, this systematic review and meta-analysis was designed to investigate whether gender difference existed in patients with coronary artery disease after percutaneous coronary intervention. METHODS PubMed, Embase, and the Cochrane Library database were searched up to February 10, 2018. Studies comparing the gender-specific effect on clinical outcomes of patients with coronary artery disease after percutaneous coronary intervention were identified, to analyze mortality, major adverse cardiovascular events (MACE) and revascularization. Statistical software RevMan was utilized in this meta-analysis. RESULTS A total of 49 studies, involving 1,032,828 patients (774,115 males and 258,713 females) reporting gender-specific outcomes, were included in this study. The in-hospital mortality, 30-day mortality, 1-year mortality, and at least 2-years mortality in male patients with coronary artery disease after percutaneous coronary intervention were significantly lower than those of females (odds ratio [OR] 0.58 95% confidence interval [CI] 0.52-0.63, P < .001; OR 0.64, 95% CI 0.61-0.66, P = .04; OR 0.67, 95% CI 0.60-0.75, P < .001 and OR 0.71, 95% CI 0.63-0.79, P = .005, respectively). The MACE was significantly decreased in male subjects after initial percutaneous coronary intervention compared with females in <1-year or at least 1-year (OR 0.67, 95% CI 0.56-0.80, P < .001 and OR 0.84, 95% CI 0.76-0.93, P < .001). The male patients after percutaneous coronary intervention harbored higher rate of revascularization compared with females for at least 1-year (OR 1.17, 95% CI 1.00-1.36, P < .001), while the rate of revascularization in male patients for < 1-year was lower than that of females (OR 0.93, 95% CI 0.69-1.26, P < .001). CONCLUSIONS The systematic review and meta-analysis suggests that the prognosis of male patients with coronary artery disease after percutaneous coronary intervention is better than that of females, except for long-term revascularization.

Abstract
A meta-analysis to determine the impact of gender on mortality in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS): PubMed, EMBASE, and Cochrane Library, was systematically searched. Two investigators independently reviewed retrieved articles and assessed eligibility. Unadjusted mortality rates or adjusted effect estimates regarding gender-specific short-term and long-term all-cause mortality were identified. A total of 30 studies involving 358,827 patients with NSTE-ACS (129, 632 women and 229,195 men) were identified. In the unadjusted analysis, women had significantly higher risk of short-term all-cause mortality (RR 1.37; 95% CI 1.26-1.49; P < 0.00001) and long-term all-cause mortality (RR 1.18; 95% CI 1.07-1.31; P = 0.001) compared with men. However, when a meta-analysis was performed using adjusted effect estimates, the association between women and higher risk of short-term mortality (RR 0.99; 95% CI 0.91-1.07; P = 0.74) and long-term all-cause mortality (RR 0.84; 95% CI 0.68-1.03; P = 0.09) was markedly attenuated. Adjusted short-term and long-term all-cause mortality appeared similar in women and men. In conclusion, women with NSTE-ACS have higher short-term and long-term mortality compared with men. However, gender differences do not differ following adjustment for baseline cardiovascular risk factors and clinical differences.

Abstract
Although differences diminish with age, outcomes are overall worse for women compared to men who present with suspected acute coronary syndrome. The reasons for this discrepancy are multifactorial, including sex-related differences in atherosclerosis biology and fluid dynamics, as well as a premature conclusion by providers that chest pain must be noncardiac in the absence of obstructive coronary artery disease. In this review of existing literature, we explore the diverse differential diagnosis in this unique set of patients. Especially in women with persistent symptoms, absence of occlusive disease should prompt consideration for subangiographic plaque disruption, epicardial or microvascular endothelial dysfunction, transient neurohormonal imbalance predisposing to Takotsubo cardiomyopathy or spontaneous coronary artery dissection, underlying systemic inflammatory conditions, thromboembolic disease, myocarditis, and sequelae of congenital heart disease. As always, a thorough history and attentive physical exam will help guide further work-up, which in many cases may warrant noninvasive imaging, such as contrast-enhanced echocardiography, cardiac magnetic resonance imaging, or positron emission tomography, with their respective means of measuring myocardial perfusion and myocardial tissue pathology. Lastly, intracoronary imaging such as intravascular ultrasound and optical coherence tomography and invasive diagnostic methods such as coronary reactivity testing continue to add to our understanding that what appear to be atypical presentations of ischemic heart disease in women may in fact be typical presentations of pathologic cousin entities that remain incompletely defined.

Abstract
Cardiovascular disease is the leading cause of death amongst women, with acute coronary syndromes (ACS) representing a significant proportion. It has been reported that in women presenting with ACS there is underdiagnosis and consequent undertreatment leading to an increase in hospital and long-term mortality. Several factors have to be taken into account, including lack of awareness both at patient and at physician level. Women are generally not aware of the cardiovascular risk and symptoms, often atypical, and therefore wait longer to seek medical attention. In addition, physicians often underestimate the risk of ACS in women leading to a further delay in accurate diagnosis and timely appropriate treatment, including cardiac catheterisation and primary percutaneous coronary intervention, with consequent delayed revascularisation times. It has been acknowledged by the European Society of Cardiology that gender disparities do exist, with a Class I, Level of Evidence B recommendation that both genders should be treated in the same way when presenting with ACS. However, there is still a lack of awareness and the mission of Women in Innovation, in association with Stent for Life, is to change the perception of women with ACS and to achieve prompt diagnosis and treatment.

Abstract
BACKGROUND This study was performed to assess the influence of sex on drug therapy and long-term outcomes in acute coronary syndrome (ACS) patients who underwent percutaneous coronary intervention (PCI). METHODS This is a retrospective cohort study of ACS patients who underwent PCI [women (n=8,884) and men (n=23,937)] between January 1, 2006, and December 31, 2007, with at least a 1-year follow-up, based on the National Health Insurance Research Database in Taiwan. Propensity score was used to identify a 1:1 matched cohort (n=17,768) for multivariable adjustment. The influence of sex on drug therapy and outcomes was examined by multivariate logistic regression and multivariable Cox proportional hazards regression. RESULTS Female patients had an 18% and 12% lower likelihood of receiving aspirin (adjusted odds ratio [OR(adj)]=0.82, 95% confidence interval [CI]=0.77-0.88) and clopidogrel (OR(adj)=0.88, 95% CI=0.81-0.95), respectively, than male patients but had a 17% and 22% higher likelihood of receiving beta-blockers (OR(adj)=1.17, 95% CI=1.10-1.24) and statins (OR(adj)=1.22, 95% CI=1.14-1.29), respectively, than male patients in the matched cohort. The adjusted hazard ratio (HR(adj)) of rehospitalization for revascularization in women was 0.84 (95% CI=0.79-0.90) compared with men after at least a 1-year follow-up in the matched cohort. CONCLUSIONS Female patients with ACS who underwent PCI were less likely to receive aspirin and clopidogrel but were more likely to receive beta-blockers and statins than male patients. Male sex was associated with a higher risk of rehospitalization for revascularization than female sex.

Abstract
While outcomes for ST-segment-elevation myocardial infarction has significantly decreased over the last years, patients presenting with non-ST-segment-elevation acute coronary syndromes (NSTEACS) still have a rather high mortality. Longer term mortality over 4 years is about double the mortality after a ST-segment-elevation myocardial infarction. The reason for the poorer prognosis is unclear but is very likely to be partially explained by the generally older age of NSTEACS patients. The optimal therapy for NSTEACS is less well defined. In this review, the authors specifically discuss the role of coronary angiography, how to decide which patient should undergo this procedure and whether there is an optimal time point. The review provides an up-to-date discussion about the best treatment strategies for NSTEACS.

Abstract
BACKGROUND It is under discussion whether female patients with non-ST-elevation myocardial infarction (NSTEMI) benefit from routine invasive treatment strategy. We accordingly applied our data from the Berlin Myocardial Infarction Registry (BMIR) to analyze the association between early percutaneous coronary intervention (PCI) and hospital mortality in NSTEMI patients. METHODS Data prospectively collected in the BMIR between 2004 and 2008 from 2808 patients (m=1820/w=988) directly admitted to hospitals with 24-h PCI facilities were included in the analysis. After adjustment for confounding variables, we compared in-hospital mortality for patients of both sexes with vs. without early PCI. RESULTS Women with NSTEMI were, on average, 7years older than men and demonstrated significantly more comorbidities. A GPIIb/IIIa antagonist was applied in women less often than in men (31.4% vs. 38.4%, p=0.001), and an early PCI was also performed less often in women than in men (64.0% vs. 76.2%, p<0.001). In-hospital mortality was higher in women than in men (5.4% vs. 3.6%, p=0.027). In female patients with NSTEMI, after adjustment for differences in patients' characteristics, hospital mortality did not differ between those treated with early PCI and those managed conservatively (OR: 1.24, 95% CI 0.53-2.91). In contrast, hospital mortality in male patients was lower in those treated with an early PCI (OR: 0.41, 95% CI 0.21-0.78). CONCLUSION In our clinical registry, early PCI in female patients with NSTEMI was not associated with lower hospital mortality. Further randomized-controlled trials are needed to better understand which women may benefit from early invasive therapy, and under which conditions such benefits are possible.

Abstract
Introduction: Prior studies have demonstrated evidence of a disparity in the treatment and outcome of male compared to female patients undergoing percutaneous coronary intervention (PCI). Materials and Methods: From a dedicated database, we retrospectively analysed all consecutive patients with acute coronary syndrome (ACS) admitted to our institution for PCI in 2008. Baseline and procedural characteristics as well as complications were then evaluated for male patients (n = 331) as compared with female patients (n = 137). Results: Women were noted to be older at the time of presentation (66.1 ± 10.0 vs 60.7 ± 11.6 years, P <0.00001), the groups were otherwise well matched in terms of baseline characteristics. Female patients were treated with significantly smaller diameter stents (2.86 ± 0.44 vs 2.96 ± 0.50 mm, P = 0.04), though the proportion of drug-eluting stents was similar (53.7% vs 50.5%, P = 0.5). Female patients were significantly less likely to receive optimal medical therapy with lesser use of glycoprotein IIb/IIIa inhibitor (26.3% vs 55.3%, P <0.0000001), and beta-blockers (83.9% vs 90.9%, P = 0.04). At 30 days, there were no differences in the rate of major adverse cerebrovascular or cardiac events (2.9% vs 3.9%, P = 0.8), though females had a significantly higher rate of femoral access site pseudoaneurysm (4.4% vs 0.9%, P = 0.02). Conclusions: There remains evidence for continued gender disparity in contemporary practice; despite evidence for efficacy in ACS patients, females received a notably lower use of glycoprotein IIb/IIIa inhibitors and beta-blockers. Women are also significantly more likely to develop femoral access site complications with pseudoaneurysm development; it is important therefore to optimise procedures for sheath removal in female patients or give strong consideration to the use of radial access site.

Abstract
BACKGROUND Progress in management of acute myocardial infarction (AMI) might have changed the effect of gender on mortality. METHODS From May 1981 to November 2002, 1984 consecutive patients with AMI underwent emergency coronary angiography. They were divided into three groups in chronological order: group I (1981-1988, n=564); group II (1989-1995, n=678); and group III (1997-2002, n=742). Multi-variable analysis was performed using Cox's proportional hazard regression, adjusting baseline clinical and angiographical variables. RESULTS There were 405 women (20%). Thrombolysis was most frequently performed in group I (50%), balloon angioplasty in group II (71%), and stent in group III (66%), with no difference in the allocation of reperfusion therapy between men and women. Three-year mortality was significantly higher in women than in men in group I (27% vs 18%, p=0.03) and group II (23% vs 15%, p=0.048). In group III, there was no significant difference in 3-year mortality (12% vs 10%, p=0.66) between women and men. Women were associated with higher age, more diabetes, more hypertension, fewer current smokers, and less previous infarction than men. Multi-variable analysis showed that sex was not an independent predictor of 3-year mortality in the three groups. CONCLUSIONS Women with AMI who were treated mostly with primary intervention using stent in the contemporary era had similar mortality to men.

Abstract
OBJECTIVE Women with acute coronary syndromes (ACS) have worse outcomes than men. Data on sex differences of culprit plaque characteristics are lacking. Intravascular optical coherence tomography (OCT) is a high-resolution imaging technique capable of in-vivo plaque characterization. The aim of this study was to compare culprit plaque characteristics in women and men presenting with ACS. METHODS Patients undergoing coronary angiography after ACS were enrolled. We performed OCT imaging on the culprit lesions. Previously validated criteria for OCT plaque characterization were used: lipid was quantified on cross-sectional image and lipid-rich plaque was defined as > or = 2 involved quadrants; fibrous cap thickness was measured at the thinnest point and thin-cap fibroatheroma was defined as lipid-rich plaque with fibrous cap thickness less than 65 microm. RESULTS Forty-two patients (33 men and nine women) were included. No significant sex differences were found in baseline characteristics. Lipid-rich plaques were identified in majority of patients. No significant difference, however, was seen in the frequency of lipid-rich plaques, thin-cap fibroatheroma or minimum fibrous cap thickness (79 vs. 89%; 45 vs. 67%; 53.8 vs. 45.4 microm, respectively; P=NS) between men and women. Incidence of calcification, thrombus and plaque disruption were also similar. CONCLUSIONS No significant sex difference was seen in culprit plaque characteristics determined by OCT imaging in patients who presented with ACS.

Abstract
PURPOSE OF REVIEW There are some striking sex differences regarding presentation, symptoms and sign, diagnosis, and treatment of coronary artery disease. Historically, healthcare delivery to women has been plagued with treatment bias favoring men. This review will present relevant cardiovascular physiologic sex differences, current treatment options for coronary artery disease both surgical and medical, and clinical outcomes of such treatments. RECENT FINDINGS In the past, pharmacologic and interventional studies generally excluded women from their subjects. As a result, women have been traditionally treated based on the findings in their male counterparts. Recent studies examining sex differences in the treatment of coronary artery disease have given new insight into the hormonal and behavioral influences associated with coronary artery disease. Finally, these studies have drawn attention to possibly inadvertent discrepancies in the way men and women are treated for coronary artery disease. SUMMARY Despite significant advances in medical and surgical approaches to treat coronary artery disease, it remains and will continue to be the most important healthcare challenge of the 21st century. Whereas efforts are underway to encourage inclusion of more women in therapeutic trials, the educational process, particularly in medical school, needs to broadly address sex specific pathophysiology and treatment, rather than relying on sub-subspecialty training for optimizing healthcare delivery in women.

Abstract
Acute coronary syndrome (ACS) is common in women, yet we have less sex-specific data in women than in men as a result of lower enrollment in clinical trials and low rates of sex-specific reporting. Women are generally older with more comorbidities when diagnosed with ACS. Women with ACS are less likely than men to be referred for invasive evaluation and procedures and are more likely to have normal coronary arteries when they are referred for coronary angiography. For reasons that are not well understood, women have higher rates of bleeding complications compared with men. This higher bleeding rate is consistently seen in many trials. There are 3 major randomized, controlled trials that compared early invasive therapy with conservative strategy for ACS. Two of these trials found higher rates of myocardial infarction (MI) and death at 1 year in women treated with early invasive strategy, whereas the third trial found a reduction in the composite end point of rehospitalization, MI, and death at 180 days in women treated with early invasive strategy. Sex differences have also been seen in glycoprotein (GP) IIb/IIIa use in women with an increase in death and MI noted for GP use in women with ACS. Continued and increased numbers of women in clinical studies of ACS as well as increased rates of sex-specific reporting will allow us to offer optimal quality care for women and men with ACS.
