老年急性冠状动脉综合征患者性别分析

目的初步探讨老年急性冠状动脉综合征(ACS)患者冠状动脉病变程度以及危险因素的差异。方法选择年龄≥60岁的ACS患者462例,其中ST段抬高急性心肌梗死患者237例,非ST段抬高急性心肌梗死患者55例,不稳定性心绞痛患者170例,分析比较男性和女性患者ACS临床分型,高血压、糖尿病、高脂血症、吸烟等危险因素伴发情况,冠状动脉病变程度及各项生化指标。结果与男性比较,女性患者年龄、糖尿病、高脂血症明显升高(P0.05,P0.01);非ST段抬高急性心肌梗死、不稳定性心绞痛、2支病变、3支病变、≥2个危险因素、TC和LDL-C均明显升高,血尿酸及入院血清总胆红素明显降低(P0.01)。结论男性多表现为ST段抬高,女性多表现为非ST段抬高。男性单支病变较多,女性多支病变及合并危险因素较男性多。应激情况下男性的氧化应激激活和抗氧化能力优于女性。     

老年女性急性ST段抬高心肌梗死患者临床及冠状动脉造影特点分析

目的探讨老年女性急性ST段抬高心肌梗死患者临床及冠状动脉造影特点。方法选择经急诊PCI诊治的年龄>60岁女性急性ST段抬高心肌梗死患者90例为老年女性组;另收集同期年龄匹配的男性急性ST段抬高心肌梗死患者190例为老年男性组,对比老年女性ST段抬高心肌梗死患者的临床及冠状动脉造影特点。结果老年女性组吸烟史及糖尿病患病率明显低于老年男性组,LDL-C、高敏C反应蛋白、白细胞介素6水平明显高于老年男性组,差异有统计学意义(P<0.05,P<0.01);老年女性组平均发病年龄明显高于老年男性组,3支病变比例明显低于老年男性组,差异有统计学意义(P<0.05,P<0.01)。结论女性心肌梗死发病年龄较晚,3支病变比例低;肥胖、LDL-C升高及炎性反应是女性心肌梗死的重要危险因素。     

非ST段抬高急性冠状动脉综合征危险分层

非ST段抬高急性冠状动脉综合征（NSTEACS）是急性冠状动脉综合征中的一种,隶属于冠状动脉粥样硬化性心脏病。NSTEACS主要由不稳定型心绞痛（UA）和非ST段抬高心肌梗死（NSTEMI）两部分构成,后者80%~90%演变为非Q波性急性心肌梗死（NQWMI）,10%~20%演变为Q波性急性心肌梗死（QWMI）。NSTEACS的病理生理基础是冠状动脉内不稳定的粥样硬化斑块在一系列炎症因子刺激下发生溃疡、破裂,以激活局部血小板,使其发生聚集,形成血栓导致血管不完全闭塞,可进一步发展为完全闭塞[1]。临床可有多种表现,包括劳力后胸前区疼痛（可由劳累、情绪激动、饱食、受寒引起）,持续性胸前区疼痛等,其流行病学特征与冠心病一致,患者年龄多在40岁以上,男性多于女性。在临床特征方面,NSTEACS的患者相对于ST段抬高急性冠状动脉综合征患者较少发生梗死相关血管完全闭塞（20%~30%）,但多支血管病变和陈旧性心肌梗死发生率较ST段抬高者多见,且更多合并糖尿病、高血压、心力衰竭和外周血管疾病,故其病死率与ST段抬高急性冠状动脉综合征患者相似,约为12%[2]。     

女性急性ST段抬高型心肌梗死患者的临床特点

目的探讨女性急性ST段抬高型心肌梗死患者的临床特点。方法选取2014年9月至2016年12月首都医科大学附属北京天坛医院心血管内科诊断为急性ST段抬高型心肌梗死并行急诊冠状动脉造影的患者452例,按性别分为两组,女性组102例,男性组350例。回顾性分析患者一般临床资料、冠状动脉造影、实验室检查、心脏功能和结构及住院期间病死率。结果与男性组相比,女性组发病年龄大[(66.4±10.6)岁比(58.4±11.1)岁,P0.001],就诊时间晚[(4.6±4.9)h比(2.6±1.9)h,P0.001],GRACE评分高(206.5±45.1比186.7±50.5,P0.001)。此外,女性单支血管病变比例低(14.7%比32.6%,P=0.037),术后发生慢血流及使用IABP比例高(11.8%比4.6%,P=0.008;11.8%比5.4%,P=0.026)。女性组的肌酸激酶同工酶MB、高敏肌钙蛋白I和B型利钠肽峰值均显著高于男性组,超声心动图显示左心室射血分数显著低于男性组(53.9%±10.3%比57.9%±8.2%,P0.001)。女性组的住院期间病死率显著高于男性组(7.8%比2.3%,P=0.013)。结论女性急性ST段抬高型心肌梗死患者发病年龄大,就诊时间晚,冠状动脉造影显示病变重,血管开通后发生慢血流比例高,术后心功能差,住院病死率高。     

非ST段抬高急性心肌梗死患者的临床特点及不良事件发生率分析

目的探讨非ST段抬高急性心肌梗死的临床特点及住院不良事件发生率。方法回顾性分析我院急性心肌梗死患者105例,分为ST段抬高组（n=68）和非ST段抬高组（n=37）,分析比较两组患者的冠状动脉造影特点及住院不良事件发生率。结果冠状动脉造影示病变血管数差异无显著性意义（P〉0．05）;非ST段抬高组以老年人多见（71％）,其中〉60岁的女性患者占41％,相关血管不完全闭塞比例较高、累及非主支血管较多,且梗死相关血管周围多有侧支循环形成。非ST段抬高组总住院不良事件（包括心力衰竭、再次心肌梗死、再次冠脉介入治疗和脑卒中等）的发生率明显较低,差异有显著性意义（P〈0．01）,但住院病死率和消化道出血发生率差异无显著性意义（P〉0．05）。结论非ST段抬高者以老年、女性患者居多,临床表现和冠状动脉造影的结果不典型,但有较好的近期预后。     

aVR导联ST段改变对急性非ST段抬高型心肌梗死相关血管的判定及临床意义

目的探讨体表心电图a VR导联ST段改变对急性非ST段抬高型心肌梗死病人梗死相关血管(IRA)的判定及临床意义。方法回顾性分析230例临床确诊为急性非ST段抬高型心肌梗死病人的临床资料、心电图及冠状动脉造影结果。依据心电图a VR导联ST段变化将病例分为A组(ST抬高组)、B组(ST下移组)和C组(ST无偏移组)。结果冠状动脉造影结果:ST抬高组左主干病变、左前降支病变的发生率明显高于ST下移组和ST无偏移组,差异有统计学意义(P0.05);ST下移组左回旋支病变及右冠状动脉病变的发生率明显高于ST抬高组和ST无偏移组,差异有统计学意义(P0.05);ST抬高组和ST下移组双支病变及三支病变的发生率明显高于ST无偏移组,差异均有统计学意义(P0.05)。a VR导联ST段抬高组、下移组主要不良心血管事件发生率均明显高于ST无偏移组(P0.05)。结论急性非ST段抬高型心肌梗死病人如果伴有a VR导联ST段抬高或下移可能提示梗死相关血管为左主干病变、左前降支病变、左回旋支病变、右冠状动脉病变或严重的多支病变,且住院期间不良心血管事件发生率增高。a VR导联ST段改变对急性非ST段抬高型心肌梗死病人梗死相关血管的判定及临床预后均具有重要的临床指导意义。     

首次急性ST段抬高与非ST段抬高心肌梗死患者临床及冠状动脉病变特点比较

目的回顾性分析比较首次发生急性ST段抬高心肌梗死与非ST段抬高心肌梗死的临床及冠状动脉病变的特点。方法选择首次急性ST段抬高心肌梗死患者50例(ST段抬高组)和急性非ST段抬高心肌梗死患者50例(非ST段抬高组),均行冠状动脉造影检查,对其发病特点、临床表现、并发症、心功能以及冠状动脉病变进行回顾性分析。结果 ST段抬高组起病急,主要以剧烈胸痛为主,就诊时间较早,非ST段抬高组首发症状多样。ST段抬高组总并发症、室性心律失常、窦性心动过缓及传导阻滞发生率明显高于非ST段抬高组(P<0.01),左心室射血分数明显低于非ST段抬高组(P<0.05)。与ST段抬高组比较,非ST段抬高组冠状动脉病变血管支数较多,3支病变、侧支循环比例较高(P<0.05,P<0.01)。结论急性ST段抬高心肌梗死起病急,并发症多,影响心功能,应积极尽快实施血运重建,以开通梗死相关血管,但急性非ST段抬高心肌梗死冠状动脉病变往往较重。急性心肌梗死的近期预后与起病急缓、透壁性心肌坏死范围等有关。     

急性非ST段抬高性心肌梗死患者冠状动脉病变特点及其临床意义

目的分析急性非ST段抬高性心肌梗死患者冠状动脉病变特点及其临床意义。方法选择冠状动脉造影资料与临床资料完整的急性非ST段抬高性心肌梗死83例,以及同期急性ST段抬高性心肌梗死109例,分别就冠状动脉病变支数、狭窄程度、侧枝循环形成情况及临床特征进行对比分析。结果急性非ST段抬高性心肌梗死患者单支病变较ST段抬高性心肌梗死患者少(P<0.05),非ST段抬高性心肌梗死患者三支病变较ST段抬高性心肌梗死患者多(P<0.05),非ST段抬高性心肌梗死患者≥90%的狭窄病变较ST段抬高性心肌梗死患者多,但<90%的狭窄病变较ST段抬高性心肌梗死患者少(P<0.05),而两组间血管100%闭塞情况相似(P>0.05);非ST段抬高性心肌梗死患者Ⅱ级以上的侧枝循环较ST段抬高性心肌梗死患者多见(P<0.05);非ST段抬高性心肌梗死患者既往心绞痛与陈旧性心肌梗死病史多见(P<0.05),肌酸激酶同工酶峰值较ST段抬高性心肌梗死组明显要低(P<0.01),急性肺水肿、心源性休克、致死性心律失常等严重急性并发症比ST段抬高性心肌梗死组明显要少(P<0.05),左心室射血分数、住院期间死亡率和随访3年的冠心病死亡率与ST段抬高性心肌梗死组相似(P>0.05),而梗死后心绞痛比ST段抬高性心肌梗死组则明显增多(P<0.05)。结论急性非ST段抬高性心肌梗死冠状动脉病变相对复杂,多支及严重狭窄病变多,发作前多已有缺血预适应,且侧枝循环多见,这是心肌梗死形成非ST段抬高的主要原因,也决定了非ST段抬高性心肌梗死患者的临床特征。     

急性冠脉综合征心电图改变的相关因素分析

目的分析急性冠脉综合征患者心电图改变的相关因素。方法对急性冠脉综合征患者进行回归性分析,按心电图类型进行一般资料与冠脉造影结果的相关性分析。结果一般资料、吸烟史、血脂异常、糖尿病与高血压对其产生影响,相关性分析可知,冠脉造影结果中不稳定型心绞痛(UAP)单支、双支及三支病变发生率分别为58.0%、25.9%、16.1%,非ST段抬高型心肌梗死(NSTEMI)患者单支、双支及三支病变发病率分别为26.4%、32.2%、41.4%,与ST段抬高心肌梗死(STEMI)患者的单支、双支及三支病变发病率比较有统计学意义(P0.05)。STMEI患者ST段抬高振幅、冠脉病变支数与狭窄程度有相关性(P0.05)。NSTEMI患者的ST低振幅、冠脉病变支数与狭窄程度具有相关性(P0.05)。STMEI患者ST段抬高振幅与冠脉病变支数与狭窄程度的有相关性(r=0.393,P=0.006)。结论心电图指标可以初步判断冠状动脉的病变支数与狭窄程度,能够帮助结合冠脉造影术提供更为早期、及时有效的治疗及预后价值。     

35岁以下急性心肌梗死患者危险因素及冠状动脉特征

目的:探讨年龄≤35岁急性心肌梗死(AMI)患者的危险因素及冠状动脉病变特点。方法:回顾我院2010年10月至2011年12月,行冠状动脉造影的年龄≤35岁96例(A组)和200例年龄35岁AMI患者的临床和冠状动脉造影资料,分析其冠心病危险因素及冠状动脉病变特点等。结果:与年龄35岁AMI患者相比,≤35岁患者在男性、超质量、肥胖、吸烟及急性ST段抬高型心肌梗死比例较高(96.5%vs.70.0%;75%vs.45.5%;35.4%vs.17.5%;72.9%vs.49.0%;93.8%vs.79.5%,P0.05),而高血压、糖尿病及血脂异常较低(P0.05)。≤35岁患者中,12例患者冠状动脉造影正常,单支病变发生率高;而年龄35岁AMI患者以3支血管病变为主。结论:≤35岁AMI患者的主要危险因素是吸烟和肥胖,大部分为ST段抬高型AMI,病变以单支冠状动脉病变为主。     

老年急性冠脉综合征的临床研究

目的 探讨老年男性与女性患者急性冠脉综合征(ACS)、冠脉高危因素、冠脉造影结构、冠脉血管再通术、住院期间死亡及复发心梗的特点.方法 177例ACS老年患者,诊断为ST段抬高AMI、非ST段抬高AMI及不稳定型心绞痛,行冠脉造影检查.结果 老年男性患者心梗史、冠脉再通史、周围血管病变史、吸烟史均高于女性,冠脉高危因素高于女性.结论 老年男性比女性患者有更高的三支血管病变发生,因ACS住院的老年患者冠脉高危因素及完全性闭塞病变比例更高.     

经皮冠状动脉介入治疗的3 049例男性和1 878例女性老年患者的临床特征及其性别差异

目的：观察确诊为冠心病并行经皮冠状动脉介入治疗（PCI）的老年患者的临床特征,分析冠心病危险因素在不同性别人群中的差异以及不同性别患者PCI预后的差异。方法本研究回顾性地分析自2008年7月至2012年11月在沈阳军区总医院年龄＞65岁确诊为冠心病并行PCI治疗的患者4927例,按性别分为两组,其中男性3049例,女性1878例,统计其临床特征、冠状动脉造影及PCI结果、围术期抗栓治疗药物及其他心血管药物的使用情况、院内主要心脑血管不良事件（MACCE）的发生情况,分析总结两组患者各自的特点及差异。结果冠心病危险因素中,男性患者吸烟比例和肾功能不全的发病率较女性高（51.5% vs 15.3%,P＜0.01;22.1% vs 15.3%,P＜0.01）;而女性患者体质量指数[（24.8±4.4） vs （24.5±3.7）kg/m2,P＜0.05]和发病年龄更高[（72.6±4.8） vs （72.2±5.4）岁,P＜0.01],患有高血压、糖尿病的患者比例也较男性高（70.5%vs 60.8%,P＜0.01;32.2%vs 24.9%,P＜0.01）。两组术后MACCE发生率差异无统计学意义,但女性死亡率高于男性（0.6% vs 0.1%,P＜0.01）。结论在接受PCI的人群中,老年女性较男性拥有更多的冠心病危险因素,且PCI预后也较男性差。     

The dilemma of success: percutaneous coronary interventions in patients > or = 75 years of age-successful but associated with higher vascular complications and cardiac mortality.

Elderly patients are increasingly referred to percutaneous coronary interventions (PCIs). Recent reports suggest complications rates are declining in the elderly. We sought to determine whether procedural and in-hospital outcomes are different in patients aged > or = 75 years undergoing nonemergent PCI as compared to patients age < 75 years. The outcome of 266 consecutive patients age > or = 75 years undergoing nonemergent PCI was compared to that of 1,681 consecutive patients age < 75 years. Compared with younger patients, greater proportions of elderly patients were women and had a history of hypertension, peripheral vascular disease, and cerebral vascular events. Elderly patients had more extensive coronary involvement. Procedural success was similar in both groups (94%). The in-hospital cardiac death rate was significantly higher in the elderly patients (2.3% vs. 0.7%; P = 0.03). Aged patients also had a significantly higher incidence of vascular and bleeding complications. Blood transfusion was required more often in the elderly group (4.5% vs. 2.6%; P = 0.07). The hospitalization length was significantly higher in the elderly group (4.1 +/- 6.0 vs. 2.5 +/- 4.3 day; P = 0.0004). By multivariate logistic regression (adjusted for baseline clinical and angiographic variables), age > or = 75 years was found to be an independent predictor of in-hospital cardiac death (odds ratio = 3.9; 95% CI = 1.3-11.5; P = 0.015). Although PCI is technically successful in patients aged > or = 75 years; it is associated with more acute cardiac and vascular complications and higher in-hospital cardiac mortality.     

75岁以上老人经皮冠状动脉介入治疗后短期疗效的性别差异

目的：研究≥75岁的冠心病患者行经皮冠状动脉介入治疗（PCI）术后住院期间的疗效是否有性别差异。方法从2005年1月到2010年12月502名接受了PCI术的≥75岁老年患者入选本研究,其中36.5%为女性,63.5%为男性。对不同性别患者临床特点和住院期间的疗效进行了比较。结果502名患者年龄为（78.5±3.2）岁,平均住院日（23.2±6.5）d。男性与女性相比,ST段抬高型心肌梗死的发病率高,而心力衰竭的发病率低。男性与女性住院期间的手术成功率（94.3%vs 94.5%, P＝1.000）和死亡率（1.3%vs 3.5%,P＝0.093）差异没有统计学意义。结论在≥75岁的老年冠心病患者中行PCI手术具有高成功率和可接受的死亡率。尽管男性的基础临床情况更差一些,但在接受PCI术的老年患者中,住院期间的结果没有性别差异。     

Gender-based outcomes among patients with diabetes mellitus after percutaneous coronary intervention in the drug-eluting stent era

Diabetes mellitus has a greater effect on mortality rates due to coronary artery disease in women than in men. Although women undergoing coronary intervention in general have a higher frequency of adverse outcomes than men, the effect of gender among diabetic patients on clinical outcomes after percutaneous coronary intervention (PCI) has not been well established in the drug-eluting stent (DES) era. We have investigated the impact of gender on long-term clinical outcome in these high risk populations. We enrolled 404 consecutive patients (74 women and 330 men) with diabetes mellitus who underwent elective PCI (85% with DES). We evaluated the incidence of major adverse cardiac events (MACE), which is a composite of total all-cause death, acute coronary syndrome (ACS), and target lesion revascularization (TLR) during a period of 4 years after coronary intervention. The women were significantly older, more likely to have dyslipidemia, and had significantly higher systolic blood pressure and LDL-C values than men. The use of insulin and angiotensin receptor blockers was more frequent among the women (32.4% versus 21.0%, P = 0.04 and 60.8% versus 39.8%, P < 0.01, respectively). The angiographic profiles of both were comparable. At four-year clinical follow-up, cumulative incidence of MACE was identical between the women and the men (16.2% versus 15.5%, P = 0.90; adjusted HR 1.23, 95% CI 0.61-2.50, P = 0.56). Although the baseline characteristics of the women were worse, clinical outcomes did not significantly differ between women and men among diabetic patients after elective PCI.     

Mortality, risk indicators of death, mode of death and symptoms of angina pectoris during 5 years after coronary artery bypass grafting in men and women

AIM: To describe mortality, risk indicators of death, mode of death and symptoms of angina pectoris during 5 years after coronary artery bypass grafting in women and men. SAMPLE: All patients in western Sweden who underwent coronary artery bypass grafting without concomitant valve surgery and without previously performed coronary artery bypass grafting between June 1988 and June 1991. RESULTS: In all, 2000 patients participated in the evaluation, 381 (19%) of whom were women. Compared to men, who had a 5-year mortality of 13.3%, women had a relative risk of death of 1.4 (95% CI 1.0-1.8; P = 0.03). Renal dysfunction interacted significantly (P = 0.048) with gender, in that the differences were more marked in patients without renal dysfunction. When adjusting for differences at baseline, the relative risk of death amongst women was 1.0 (95% CL 0.7-1.3). Compared to men, women had an increased risk of in-hospital death and death associated with stroke. However, amongst the patients who died, the place and mode of death appeared to be similar in women and men. Amongst survivors after 5 years, women had more symptoms of angina pectoris than men. CONCLUSION: During 5 years after coronary artery bypass grafting, women had an increased mortality compared to men; renal dysfunction seemed to interact with female gender regarding mortality. Women had a higher risk of in-hospital death and death associated with stroke. However, the adjusted relative risk of death during 5 years was equal in women and men. Amongst survivors, women suffered more from angina pectoris than men.     

Diabetes mellitus: clinical presentation and outcome in men and women with acute coronary syndromes. Data from the Euro Heart Survey ACS.

AIMS: To study clinical presentation, in-hospital course and short-term prognosis in men and women with diabetes mellitus and acute coronary syndromes (ACS). METHODS: Men (n = 6488, 21.2% with diabetes) and 2809 women (28.7% with diabetes) < or = 80 years old, with a discharge diagnosis of ACS were prospectively enrolled in the Euro Heart Survey of ACS. RESULTS: Women with diabetes were more likely to present with ST elevation than non-diabetic women, a difference that became more marked after adjustment for differences in smoking, hypertension, obesity, medication and prior disease [adjusted odds ratio (OR) 1.46 (1.20, 1.78)], whereas there was little difference between diabetic and non-diabetic men [adjusted OR 0.99 (0.86, 1.14)]. In addition, women with diabetes were more likely to develop Q-wave myocardial infarction (MI) than non-diabetic women [adjusted OR 1.61 (1.30, 1.99)], while there was no difference between men with and without diabetes [adjusted OR 0.99 (0.85, 1.15)]. There were significant interactions between sex, diabetes and presenting with ST-elevation ACS (P < 0.001), and Q-wave MI (P < 0.001), respectively. Of the women with diabetes, 7.4% died in hospital, compared with 3.6% of non-diabetic women [adjusted OR 2.13 (1.39, 3.26)], whereas corresponding mortality rates in men with and without diabetes were 4.1% and 3.3%, respectively [OR 1.13 (0.76, 1.67)] (P for diabetes-sex interaction 0.021). CONCLUSION: In women with ACS, diabetes is associated with higher risk of presenting with ST-elevation ACS, developing Q-wave MI, and of in-hospital mortality, whereas in men with ACS diabetes is not significantly associated with increased risk of either. These findings suggest a differential effect of diabetes on the pathophysiology of ACS based on the patient's sex.     

冠心病患者经皮冠状动脉介入治疗死亡率的性别差异

目的确定经皮冠状动脉介入治疗(PCI)后死亡率是否存在性别差异以及女性是否是影响死亡率的独立预测因素。方法回顾性分析2004年7月1日至2005年9月30日北京安贞医院行单纯PCI治疗的2 493名患者(男性1 860例,女性633例),并进行随访,记录临床特征及随访数据。按照性别分组比较两组之间住院死亡率和总死亡率的差异。结果女性年龄较大,术前合并主要疾病的比例较男性高,而左室射血分数(LVEF)较男性好,既往心肌梗死病史及血运重建史较男性少。女性患者术后住院死亡率约是男性的10倍(女性1.1%,男性0.1%,P<0.001);中位数随访时间555 d,随访率93.4%,女性总死亡率高于男性(5%比2%,P=0.003),总死亡风险是男性的2.6倍(HR2.631,95%CI1.217~5.687,P=0.014)。结论女性PCI术后住院死亡率及总死亡率均高于男性。女性是总死亡率的独立危险因素。     

性别和年龄对中国人冠状动脉旁路移植术后住院病死率的影响

目的确定中国人冠状动脉旁路移植术后住院病死率是否存在性别差异以及该差异是否与年龄相关.方法回顾性分析1997年1月1日至2001年12月31日阜外心血管病医院外科全部接受冠状动脉旁路移植术的患者共2682例（男性2316例,女性366例）.按照性别和年龄分组调查它们之间的围手术期并发症及手术后住院病死率的差异.结果女性术前合并主要疾病的比例比男性高,术后并发症多,但她们术前的左心室射血分数较男性好,且冠状动脉病变数量少.然而,女性患者的术后住院病死率是男性的3倍（女性3.01%,男性1.12%,P=0.001）,病死率的性别差异在低龄组更有统计学意义（女性2.6%,男性0.5%,P=0.001,ORs：4.844,95%可信区间：1.549～15.142）,在老年患者中则无统计学意义（女性3.7%,男性2.4%,P=0.383）.结论中国女性冠状动脉旁路移植术的住院病死率高于男性,特别是低龄女性.低龄组女性是住院病死率的独立危险因素.死亡率的性别差异随年龄增加而减少.需要进一步的研究来阐明病死率的性别差异在低龄组更显著的原因.     

Comparison of results of percutaneous coronary intervention for non-ST-elevation acute myocardial infarction or unstable angina pectoris in men versus women

Previous randomized trials have addressed the impact of gender on outcomes, showing worse results in women assigned to invasive strategies compared with men with non-ST-elevation (NSTE) acute coronary syndrome (ACS). However, there is still a significant amount of controversy on strategies of treatment on the basis of gender. This study evaluated the impact of gender on treatment strategies and outcomes in patients with NSTE ACS in a high-volume, single-site tertiary center. We identified 1,197 consecutive patients with NSTE ACS (381 women, 816 men) who underwent percutaneous coronary intervention during their index hospitalizations. Patients were stratified by gender and baseline clinical and angiographic characteristics, and in-hospital and 9-month clinical outcomes were compared between the 2 groups. There were clear differences in baseline characteristics between men and women with ACS at presentation. Women were, on average, slightly older than men, with more hypertension and morbid obesity, but there were no differences in racial backgrounds or the prevalence of diabetes or dyslipidemia, nor were there treatment disparities in pharmacologic interventions. Women and men with ACS had similar rates of percutaneous coronary intervention on index admission. Women had a greater incidence of bleeding complications requiring blood transfusions. Overall, in-hospital and 9-month event-free survival were equivalent for the 2 genders. In conclusion, in this single-site observational study, patients with NSTE ACS who underwent angiography followed by percutaneous coronary intervention demonstrated no significant gender differences in treatment or in-hospital or 9-month event-free survival. From these results, interventional strategies should not be based on gender.
