Abstract
INTRODUCTION Cardiac surgery may induce acute kidney injury and the need for renal replacement therapy. It is also associated with higher hospital costs, morbidity and mortality. The aims of this study were to investigate predictors of cardiac surgery associated acute kidney injury in our population and to determine the burden of acute kidney injury in elective cardiac surgery, evaluating the potential cost effectiveness of preventing it through the application of the Kidney Disease: Improving Global Outcomes bundle of care to high-risk patient groups identified by the [TIMP-2]x[IGFBP7] used as a screening test. MATERIAL AND METHODS In a University Hospital single-center retrospective cohort study we analyzed a consecutive sample of adults who underwent elective cardiac surgery between January and March 2015. A total of 276 patients were admitted during the study period. Data from all patients was analyzed until hospital discharge or the patient's death. The economic analysis was performed from the hospital costs' perspective. RESULTS Cardiac surgery associated acute kidney injury occurred in 86 patients (31%). After adjustment, higher preoperative serum creatinine (mg/L, ORadj = 1.09; 95% CI: 1.01 - 1.17), lower preoperative hemoglobin (g/dL, ORadj = 0.79; 95% CI: 0.67 - 0.94), chronic systemic hypertension (ORadj = 5.00; 95% CI: 1.67 - 15.02), an increase in cardiopulmonary bypass time (min, ORadj = 1.01; 95% CI: 1.00 - 1.01) and perioperative use of sodium nitroprusside (ORadj = 6.33; 95% CI: 1.80 - 22.28) remained significantly associated with cardiac surgery related acute kidney injury. The expected cumulative surplus cost for the hospital linked with cardiac surgery associated acute kidney injury (86 patients) was €120 695.84. Based on a median absolute risk reduction of 16.6%, by dosing kidney damage biomarkers in every patient and using preventive measures in high-risk patients, we would expect a break-even point upon screening 78 patients, which would translate, in our patient cohort, into an overall cost benefit of €7145. CONCLUSION Preoperative hemoglobin, serum creatinine, systemic hypertension, cardiopulmonary bypass time and perioperative use of sodium nitroprusside were independent predictors of cardiac surgery associated acute kidney injury. Our cost-effectiveness modelling suggests that the use of kidney structural damage biomarkers combined with an early prevention strategy could be associated with potential cost savings.

Abstract
BACKGROUND Sexual dimorphisms are well recognized in various cardiac diseases such as ischemic cardiomyopathy (ICM), hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). Thorough understanding of the underlying genetic programs is crucial to optimize treatment strategies specified for each gender. By performing meta-analysis and microarray analysis, we sought to comprehensively characterize the sexual dimorphisms in the healthy and diseased heart at the level of both mRNA and miRNA transcriptome. RESULTS Existing mRNA microarray data of both mouse and human heart were integrated, identifying dozens/ hundreds of sexually dimorphic genes in healthy heart, ICM, HCM, and DCM. These sexually dimorphic genes overrepresented gene ontologies (GOs) important for cardiac homeostasis. Further, microarray of miRNA, isolated from mouse sham left ventricle (LV) (n = 6 & n = 5 for male & female) and chronic MI LV (n = 19 & n = 19) and from human normal LV (n = 6 & n = 6) and ICM LV (n = 4 & n = 5), was conducted. This revealed that 13 mouse miRNAs are sexually dimorphic in MI and 6 in normal heart. In human, 3 miRNAs were sexually dimorphic in ICM and 15 in normal heart. These data revealed miRNA-mRNA networks that operate in a sexually-biased fashion. CONCLUSIONS mRNA and miRNA transcriptome of normal and disease heart show significant sex differences, which might impact the cardiac homeostasis. Together this study provides the first comprehensive picture of the genome-wide program underlying the heart sexual dimorphisms, laying the foundation for gender specific treatment strategies.

Abstract
Factors predisposing the older person with acute myocardial infarction (MI) to develop heart failure (HF) include an increased prevalence of MI, multivessel coronary artery disease, decreased left ventricular (LV) contractile reserve, impairment of LV diastolic relaxation, increased hypertension, LV hypertrophy, diabetes mellitus, valvular heart disease, and renal insufficiency. HF associated with acute MI should be treated with a loop diuretic. The use of nitrates, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, aldosterone antagonists, beta-blockers, digoxin, and positive inotropic drugs; treatment of arrhythmias and mechanical complications; and indications for use of implantable cardioverter-defibrillators and cardiac resynchronization is discussed.

Abstract
Evidence showing higher acute myocardial infarction (AMI) mortality rates among female compared with male inpatients has stimulated interest in whether this disparity is the result of biological factors or differences in the provision of healthcare services. We investigated the impact of sex on in-hospital mortality rates due to AMI, and evaluated the contribution of differences in the delivery of optimal medical services for AMI.We retrospectively constructed a dataset of 85,329 new patients admitted to Korean hospitals with AMI between 2003 and 2007 from the Korea National Health Insurance Claims Database. We used the claims database to provide information about treatment after admission or death for each patient.Proportionally more female than male patients aged 65 years or older had complications; however, proportionally fewer female patients underwent invasive procedures. Female patients had a higher in-hospital mortality rate than males (21.2% vs 14.6%, odds ratio [OR] 1.58, 95% confidence interval [CI] 1.52-1.64). The probability of death within 30 days after admission remained higher for females than males after adjusting for demographic characteristics and severity (OR 1.08, 95% CI 1.04-1.13). After additionally adjusting for invasive and medical management, the probability of death within 30 days did not differ between males and females (OR 1.04, 95% CI 0.99-1.08). A similar trend was revealed by an additional analysis of patients according to younger (<65 years) and older (≥65 years) age groups.The higher in-hospital mortality rates after AMI in Korean female patients was associated with a lower procedure rate. Evidence indicating that AMI symptoms differ according to sex highlights the need for health policies and public education programs that raise awareness of sex-related differences in early AMI symptoms to increase the incidence of appropriate early treatment in females.

Abstract
The total number of deaths from cardiovascular diseases (CVD) is greater for women than for men, although the mean age at manifestation of CVD is about 10 years older. However, the annual number of cases treated for CVD in acute hospital settings in men exceeds that of women by 50 %. Remarkable gender differences exist in terms of morphological and physiological conditions (e.g. mean coronary vessel diameter; ability to adapt to protective exercise-induced myocardial hypertrophy), as well as of the frequency and clinical significance of somatic risk factors (e.g. smoking). Female body weight increases after menopause and the body shape assumes a more android fat distribution. Women report higher levels of unspecific and affective symptoms. They suffer more from anxiety and depression than men; however, the secondary impact on CVD onset may be less pronounced. The post-acute CVD course is more complicated in women, mainly because they are older and suffer more from multi-morbidity. Whilst male CVD patients aim for a rapid recovery, physical fitness and an increased life expectancy, female patients seek relief from everyday challenges, the maintenance of their independence and emotional support.

Abstract
BACKGROUND Current drug therapy for acute heart failure syndromes (AHFS) consists mainly of diuretics supplemented by vasodilators or inotropes. Nitrates have been used as vasodilators in AHFS for many years and have been shown to improve some aspects of AHFS in some small studies. The aim of this review was to determine the clinical efficacy and safety of nitrate vasodilators in AHFS. OBJECTIVES To quantify the effect of different nitrate preparations (isosorbide dinitrate and nitroglycerin) and the effect of route of administration of nitrates on clinical outcome, and to evaluate the safety and tolerability of nitrates in the management of AHFS. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3), MEDLINE (1950 to July week 2 2011) and EMBASE (1980 to week 28 2011). We searched the Current Controlled Trials MetaRegister of Clinical Trials (compiled by Current Science) (July 2011). We checked the reference lists of trials and contacted trial authors. We imposed no language restriction. SELECTION CRITERIA Randomised controlled trials comparing nitrates (isosorbide dinitrate and nitroglycerin) with alternative interventions (frusemide and morphine, frusemide alone, hydralazine, prenalterol, intravenous nesiritide and placebo) in the management of AHFS in adults aged 18 and over. DATA COLLECTION AND ANALYSIS Two authors independently performed data extraction. Two authors performed trial quality assessment. We used mean difference (MD), odds ratio (OR) and 95% confidence intervals (CI) to measure effect sizes. Two authors independently assessed and rated the methodological quality of each trial using the Cochrane Collaboration tool for assessing risk of bias. MAIN RESULTS Four studies (634 participants) met the inclusion criteria. Two of the included studies included only patients with AHFS following acute myocardial infarction (AMI); one study excluded patients with overt AMI; and one study included participants with AHFS with and without acute coronary syndromes.Based on a single study, there was no significant difference in the rapidity of symptom relief between intravenous nitroglycerin/N-acetylcysteine and intravenous frusemide/morphine after 30 minutes (fixed-effect MD -0.30, 95% CI -0.65 to 0.05), 60 minutes (fixed-effect MD -0.20, 95% CI -0.65 to 0.25), three hours (fixed-effect MD 0.20, 95% CI -0.27 to 0.67) and 24 hours (fixed-effect MD 0.00, 95% CI -0.31 to 0.31). There is no evidence to support a difference in AHFS patients receiving intravenous nitrate vasodilator therapy or alternative interventions with regard to the following outcome measures: requirement for mechanical ventilation, systolic blood pressure (SBP) change after three hours and 24 hours, diastolic blood pressure (DBP) change after 30, 60 and 90 minutes, heart rate change at 30 minutes, 60 minutes, three hours and 24 hours, pulmonary artery occlusion pressure (PAOP) change after three hours and 18 hours, cardiac output (CO) change at 90 minutes and three hours and progression to myocardial infarction. There is a significantly higher incidence of adverse events after three hours with nitroglycerin compared with placebo (odds ratio 2.29, 95% CI 1.26 to 4.16) based on a single study. There was no consistent evidence to support a difference in AHFS patients receiving intravenous nitrate vasodilator therapy or alternative interventions with regard to the following secondary outcome measures: SBP change after 30 and 60 minutes, heart rate change after 90 minutes, and PAOP change after 90 minutes. None of the included studies reported healthcare costs as an outcome measure. There were no data reported by any of the studies relating to the acceptability of the treatment to the patients (patient satisfaction scores).Overall there was a paucity of relevant quality data in the included studies. Assessment of overall risk of bias in these studies was limited as three of the studies did not give sufficient detail to allow assessment of potential risk of bias. AUTHORS' CONCLUSIONS There appears to be no significant difference between nitrate vasodilator therapy and alternative interventions in the treatment of AHFS, with regard to symptom relief and haemodynamic variables. Nitrates may be associated with a lower incidence of adverse effects after three hours compared with placebo. However, there is a lack of data to draw any firm conclusions concerning the use of nitrates in AHFS because current evidence is based on few low-quality studies.

Abstract
OBJECTIVE Younger, but not older, women have a higher mortality than men of similar age after a myocardial infarction (MI). We sought to determine whether this relationship is true for both ST elevation MI (STEMI) and non-ST elevation MI (NSTEMI). DESIGN Retrospective cohort study. SETTING 1057 USA hospitals participant in the National Registry of Myocardial Infarction between 2000 and 2006. PATIENTS 126 172 STEMI and 235 257 NSTEMI patients. MAIN OUTCOME MEASURE Hospital death. RESULTS For both STEMI and NSTEMI, the younger the patient's age, the greater the excess mortality risk for women compared with men, while older women fared similarly (STEMI) or better (NSTEMI) than men (p<0.0001 for the age-sex interaction). In STEMI, the unadjusted women-to-men RR was 1.68 (95% CI 1.41 to 2.01), 1.78 (1.59 to 1.99), 1.45 (1.34 to 1.57), 1.08 (1.02 to 1.14) and 1.03 (0.98 to 1.07) for age <50 years, age 50-59, age 60-69, age 70-79 and age 80-89, respectively. For NSTEMI, corresponding unadjusted RRs were 1.56 (1.31 to 1.85), 1.42 (1.27 to 1.58), 1.17 (1.09 to 1.25), 0.92 (0.88 to 0.96) and 0.86 (0.83 to 0.89). After adjusting for risk status, the excess risk for younger women compared with men decreased to approximately 15-20%, while a better survival of older NSTEMI women compared with men persisted. CONCLUSIONS Sex-related differences in short-term mortality are age-dependent in both STEMI and NSTEMI patients.

Abstract
BACKGROUND AND OBJECTIVES Randomized trials have demonstrated that primary angioplasty is more effective than intravenous thrombolysis in reducing mortality and morbidity in patients with acute myocardial infarction (AMI). The aim of this study was to assess the in-hospital mortality of patients with AMI admitted to the only tertiary care center in Kosovo, where coronary percutaneous intervention procedures are unavailable. We also assessed the impact of age and gender on in-hospital mortality. PATIENTS AND METHODS Consecutive patients with the diagnosis of AMI, admitted in our institution between 1999 and 2007, were included in this retrospective study. RESULTS Of 2848 patients (mean age 61+/-11.3 years, 73.4% males) admitted with AMI, 292 (10.25%) patients died during in-hospital stay. The overall in-hospital mortality was 12.3% for women and 9.5% for men (P<.05). Women were significantly older than men (64.2+/-11 years vs 59.7+/-11.8 years, P<.05). Mean length of stay was 12.0+/-94 for women and 10.7+/-7.6 for men. From 1999 to 2007 there was an increase in the age of patients with AMI but the mortality rate remained stable. CONCLUSIONS Compared to developed countries, patients with AMI in Kosovo present at an earlier age but have a higher mortality rate. Women with AMI had a significantly higher in-hospital mortality rate than men. The lack of percutaneous coronary intervention procedures in AMI patients may have contributed to the high in-hospital mortality in our population.

Abstract
This article addresses issues related to acute myocardial infarction (MI) complicated by heart failure, particularly in elderly patients. Findings have shown that acute MI complicated by congestive heart failure (CHF) is associated with a high mortality, and that women with acute MI are more likely to be older and to develop CHF than men with acute MI. In general, management of CHF complicating acute MI is similar in older and younger patients. Actions discussed include hemodynamic monitoring; the administration of oxygen; and the use of morphine, diuretics, nitroglycerin, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, spironolactone, beta-blockers, calcium channel blockers, magnesium, digoxin, and positive inotropic drugs. The article also discusses measures for treating arrhythmias and for diagnosing mechanical complications.

Abstract
STUDY OBJECTIVES To assess the effect of gender on the in-hospital management of patients with acute inferior or posterior myocardial infarction (MI). DESIGN Retrospective analysis of clinical records. Gender differences in management and prognosis were assessed by stepwise multiple logistic regression analysis. SETTING University, large-volume, tertiary hospital. PATIENTS We studied 1,178 consecutive patients admitted to our coronary care unit with an acute inferior or posterior MI, and evaluated the influence of gender on clinical management and outcome. INTERVENTIONS None. MEASUREMENTS AND RESULTS Women were older (73 years vs 66 years), had a higher prevalence of diabetes and hypertension, presented later (8 h vs 6 h after symptom onset), and had a higher in-hospital mortality rate (26% vs 9%) [all p values < 0.01]. Women underwent reperfusion therapy (45% vs 61%, p < 0.01), noninvasive studies (30% vs 62%, p < 0.001), and coronary angiography (34% vs 48%, p < 0.01) less often than men. Multivariable analysis revealed that female gender was an independent predictor of a lower use of noninvasive studies (odds ratio [OR], 0.41; 95% confidence interval [CI], 0.24 to 0.63; p < 0.005) and coronary angiography (OR, 0.59; 95% CI, 0.37 to 0.93; p = 0.02). A significant interaction between age and gender was found (p = 0.002); therefore, women > or = 75 years old had a much lower probability of undergoing noninvasive tests and coronary angiography than men of the same age. CONCLUSION Despite their worse prognosis, women undergo noninvasive studies and coronary angiography less frequently than men after an acute inferior or posterior MI. The gender gap increases in patients > or = 75 years old.

Abstract
AIMS To evaluate the effect of thrombolysis on mortality and its causes in older patients with acute myocardial infarction (AMI). METHODS AND RESULTS An analysis of 706 consecutive patients > or =75 years old with a first AMI enrolled in the PPRIMM75 registry showed that although there were important differences in baseline characteristics among patients treated with thrombolysis, primary angioplasty (PA) and those who did not receive reperfusion therapy, 30 day mortality did not differ (29, 25, and 32%, respectively). The main cause of death in patients treated with thrombolysis was cardiac rupture (54%), whereas most of the other patients died in cardiogenic shock. Patients who received thrombolysis had a higher (P<0.0001) incidence of free wall rupture (FWR) (17.1%) compared with those who did not receive reperfusion therapy (7.9%) or who underwent PA (4.9%). By multivariable analysis, patients treated with thrombolytic therapy (TT) showed an excess risk of FWR (OR, 3.62; 95% CI, 1.79-7.33), a hazard not observed in patients who underwent PA. When compared with patients who did not receive reperfusion therapy, the odds ratio of 30 day mortality was 1.07 (95% CI, 0.65-1.76) for patients treated with thrombolysis and 0.78 (95% CI, 0.45-1.34) for those who underwent PA. The figures for 24 month mortality were 0.78 (95% CI, 0.65-1.76) and 0.67 (95% CI, 0.28-0.81), respectively. CONCLUSION Treatment of first AMI with TT increases the risk of FWR in very old patients, a risk not observed in patients treated with PA.

Abstract
BACKGROUND Both acute renal failure (ARF) and female sex are strongly associated with mortality after open-heart surgery. This study analyzes the effect of sex and race on the incidence of ARF after open-heart surgery and its influence on mortality. METHODS A total of 24,660 patients underwent open-heart surgery at the Cleveland Clinic Foundation (Cleveland, OH) from 1993 to 2000. The primary outcome was ARF defined as ARF requiring dialysis, 50% or greater decline in glomerular filtration rate (GFR) not requiring dialysis, or 50% or greater decline in GFR relative to baseline or requirement of dialysis. The secondary outcome was all-cause hospital mortality. RESULTS The overall frequency of ARF requiring dialysis after open-heart surgery was 1.82%. The frequency was greater in women (2.36%) than men (1.60%; P < 0.0001) and blacks (2.94%) than nonblacks (1.70%; P < 0.0001) by univariate analysis. By multivariate analysis, risk for ARF requiring dialysis in women was 1.61 (confidence interval [CI], 1.27 to 2.05; P < 0.0001), but race was not a risk factor. The overall postoperative mortality rate was 2.2%, and for patients with ARF requiring dialysis, it was 61.2% (women, 68.6% versus men, 56.5%; P = 0.01) with an odds ratio of 49.29, whereas in patients with ARF not requiring dialysis, it was 14.1% (women, 13.3% versus men 14.6%; P = 0.63) with an odds ratio of 7.18. CONCLUSION Female sex is an independent risk factor for developing ARF after open-heart surgery. The influence of race on risk for ARF is less clear. Regardless of its definition, ARF is strikingly associated with a high risk for mortality.

Abstract
The pathogenesis, clinical course, and treatment of chronic heart failure (HF) are different in elderly women from those of patients recruited in the landmark trials of chronic HF. Patients included in these landmark trials were predominantly men whose age was 10-15 years younger than the average age of patients with chronic HF in the United States. Diastolic dysfunction resulting in impaired left ventricular (LV) filling is the preponderant LV functional alteration that leads to chronic HF in elderly women. Gender differences in the LV remodeling process that accompanies chronic cardiac pressure are likely to be responsible for the preponderance of LV diastolic dysfunction over systolic dysfunction in elderly women. In response to chronic pressure overload, the LV wall becomes thicker in women than in men. Consequently, in response to chronic pressure overload, women are able to normalize LV wall stress and preserve LV systolic function to a greater extent than men. However, impaired LV filling is an undesirable consequence of the greater increase in LV wall thickness in women. Thus, clinical observations and therapeutic guidelines derived from data collected in the landmark trials of chronic HF may not apply to elderly women with chronic HF. In view of the lack of evidence-based information needed to guide the management of elderly women with chronic HF, special attention should be given to include a substantial number of elderly women in future therapeutic trials recruiting patients with chronic HF.

Abstract
PURPOSE The effects of survival after myocardial infarction on the prevalence of chronic heart failure have not been well characterized. We reviewed studies of the incidence, mortality, and predictors of heart failure after myocardial infarction, and suggest directions for further research. METHODS AND RESULTS We conducted a review of the literature from 1978 to 2000. Of 33 identified articles, 18 (55%) included heart failure as a primary endpoint. The mean in-hospital incidence of heart failure after myocardial infarction differed significantly by study design; it was highest in population-based studies and lowest in clinical trials (37% vs. 18%, P <0.01). Only 10 studies reported the incidence of subsequent heart failure. One-year mortality ranged from 16% to 39% and showed no improvement with time. Patients with in-hospital heart failure after myocardial infarction had a two- to sixfold greater in-hospital mortality and up to a fivefold increased 1-year mortality compared with patients without heart failure. The most consistent risk factors for the development of heart failure after myocardial infarction were advanced age, female sex, diabetes, and an increased heart rate at the time of admission. CONCLUSIONS The reported incidence of, and mortality from, heart failure after myocardial infarction varies by study design. Additional research on the etiology and prognosis of late heart failure after myocardial infarction is needed.

Abstract
OBJECTIVE To study gender differences in clinical status at the time of coronary revascularisation. DESIGN Retrospective study of clinical records. Two stage stratified cluster sampling was used to select a nationally representative sample of patients receiving a coronary revascularisation procedure in 1997. SETTING All of Spain. MAIN OUTCOME MEASURES Odds ratios (OR) in men and women for different clinical and diagnostic variables related with coronary disease. A logistic regression model was developed to estimate the association between coronary symptoms and gender. RESULTS In the univariate analysis the prevalence of the following risk factors for coronary heart disease was higher in women than in men: obesity (OR=1.8), hypertension (OR=2.9) and diabetes (OR=2.1). High surgical risk was also more prevalent among women (OR=2.6). In the logistic regression analysis women's risk of being symptomatic at the time of revascularisation was more than double that of men (OR=2.4). CONCLUSIONS Women have more severe coronary symptoms at the time of coronary revascularisation than do men. These results suggest that women receive revascularisation at a more advanced stage of coronary disease. Further research is needed to clarify what social, cultural or biological factors may be implicated in the gender differences observed.

Abstract
OBJECTIVES This study sought to determine the short- and long-term outcome of primary coronary angioplasty and thrombolytic therapy for acute myocardial infarction (AMI) in patients older than 75 years of age. BACKGROUND The benefit of reperfusion therapy in elderly patients with AMI is uncertain, although elderly people account for a large proportion of deaths. METHODS We randomly assigned a total of 87 patients with an AMI who were older than 75 years to treatment with angioplasty or intravenous (IV) streptokinase. Clinical outcome was measured by taking the end points of death and the combination of death, reinfarction or stroke during follow-up. RESULTS The primary end point, a composite of death, reinfarction or stroke, at 30 days had occurred in 4 (9%) patients in the angioplasty group as compared with 12 (29%) in the thrombolysis group (p = 0.01, relative risk [RR]: 4.3, 95% confidence interval [CI]: 1.2 to 20.0). At one year the corresponding figures were 6 (13%) and 18 (44%), respectively (p = 0.001, RR: 5.2, 95% CI: 1.7 to 18.1). CONCLUSIONS In this series of patients with AMI who were older than 75 years, primary coronary angioplasty had a significant clinical benefit when compared with IV streptokinase therapy.

Abstract
OBJECTIVE The ADA Study was designed to know the usual action guidelines in Spain for the diagnosis and treatment in a cohort of patients who had a recent atherothrombotic event. PATIENTS AND METHODS Cross-sectional, observational, multicenter epidemiologic study (294 hospitals) with a total of 3,512 patients enrolled. Patients had had an atherothrombotic event in the coronary or cerebral vascular territory in the previous month or were diagnosed of symptomatic peripheral arterial disease within the last 3 months. A total of 237 investigators (155 cardiologists, 113 neurologists, and 79 vascular surgeons) participated in the study. RESULTS 54.9% of patients in the study had a previous atherothrombotic event. Of these, 63.1% were on antithrombotic therapy; after the second episode, 2.6% of patients were on no preventive therapy. A great disparity and an excessive number of diagnostic tests was found to confirm the diagnosis of the current atherothrombotic event, which is in contrast with a small percentage of patients who had exams performed to confirm or rule out the atherothrombotic involvement in other vascular territories. CONCLUSIONS An appropriate protocol should be established for the diagnosis and therapy of patients with the likelihood of having clinical manifestations due to an ahterothrombotic event.

Abstract
BACKGROUND Worsening of heart failure in patients with myocardial infarction is seldom studied, elderly patients often are not included, and multivariate analysis is uncommon. AIMS The prospective PRIMA study (Prise en charge de l'Infarctus du Myocarde Aigu; management of acute myocardial infarction) sought to determine the incidence of heart failure worsening, its risk factors, and its prognostic importance in patients with myocardial infarction, regardless of age and hospital facilities, in the "real world" in a region in France, using multivariate analysis. METHODS Data were prospectively collected in all patients with myocardial infarction admitted in all hospitals in three departments in the Rhône-Alpes region in France between September 1, 1993 and January 31, 1995. RESULTS Among 2,507 patients, 33% were in Killip classes II-IV at admission. Four hundred and sixteen patients (17%) had worsening of Killip class during the first five days. In-hospital mortality (overall: 14%) increased dramatically with Killip class at admission (9% in class I; 62% in class IV) and with worsening of Killip class during the first five days (36% vs 8% if no worsening). In multivariate analysis, older age, diabetes mellitus and anterior Q-wave myocardial infarction were significant predictors of Killip class at admission and of its worsening. The significant predictors of in-hospital mortality were older age, Killip class III at admission and worsening of Killip class during the first five days. CONCLUSION This large, unselected cohort revealed that among patients with myocardial infarction, heart failure and its worsening are frequent, especially in the elderly, and dramatically worsen the in-hospital mortality.

Abstract
We examined short and long term outcomes of MI in a consecutive series of 169 men and 50 women who were followed for an average of 3.5 years. Similar percentages of men and women were admitted to medical intensive care, received in-patient cardiac rehabilitation, quit smoking at one year, were still smoking, were taking a lipid lowering drug or had returned to work at one year, underwent coronary angiography at 3.5 years or had died by 3.5 years. The lack of gender difference in outcome may reflect an absence of gender bias in the management of men and women with MI in southwest Scotland.

Worsening of heart failure in patients with myocardial infarction is seldom studied, elderly patients often are not included, and multivariate analysis is uncommon. The prospective PRIMA study (Prise en charge de l'Infarctus du Myocarde Aigu; management of acute myocardial infarction) sought to determine the incidence of worsening heart failure, its risk factors, and its prognostic importance in patients with myocardial infarction, regardless of age and hospital facilities, in the 'real world' in a region in France, using multivariate analysis. Data were prospectively collected in all patients with myocardial infarction admitted in all hospitals in three departments in the Rhône--Alpes region in France between 1 September 1993 and 31 January 1995. Among the 2507 patients included, 33% were in Killip classes II--IV at admission. After exclusion of patients with admission Killip class IV, 416 patients (17% of the cohort, 24% of women and 14% of men) had worsening of Killip class during the first 5 days. In-hospital mortality (overall, 14%) increased dramatically with Killip class at admission (9% in class I, 62% in class IV) and with worsening of Killip class during the first 5 days (36.5 vs. 8.5% if no worsening). In multivariate analysis, older age, diabetes mellitus and anterior Q-wave myocardial infarction were significant predictors of Killip class at admission and of its worsening; Killip class >I at admission was a significant predictor of Killip-class worsening. The significant predictors of in-hospital mortality were older age, Killip class III at admission and worsening of Killip class during the first 5 days. This large, unselected cohort revealed that, among patients with myocardial infarction, heart failure and its worsening are frequent, especially in the elderly, and dramatically worsen the in-hospital mortality.

Abstract
In comparing the cause of death and other cardiac morphologic findings among 60 women and 40 men aged >75 years who died of acute myocardial infarction, we found that women died more often from mechanical complications than left ventricular pump failure. Women had cardiomegaly, nonanterior location of acute myocardial infarction, healed myocardial infarcts, and dilated left ventricular cavity less often than men.

Abstract
Patients with atrial fibrillation (AF) report impaired health-related quality of life (QOL). Differences between men and women with AF have not been described and personality attributes such as somatization (tendency to amplify benign bodily sensations) may mediate potential gender differences in QOL. Patients with AF (n = 264, 59% men) who participated in the Canadian Trial of Atrial Fibrillation (n = 403) completed validated QOL questionnaires at baseline, 3 months, and 12 months after antiarrhythmic drug treatment. Women were significantly older than men and a greater proportion had hypertension, but other cardiac variables did not differ between women and men. At baseline, after controlling for significant clinical and demographic factors, women reported worse physical health (p = 0.002) and functional capacity (p < 0.001), but not mental health or general well-being. Women also had more frequent and severe cardiac symptoms than men (both p < 0.001). Physical health improved significantly from baseline to 3 months for women (p = 0.002), but not for men (p = 0.066). Conversely, mental health improved for men (p = 0.007), but not for women. Cardiac symptom frequency and severity improved over time for women and men (all p < 0.001). Tendency to somatize predicted poor QOL, and women had higher scores than men (p = 0.023). However, after controlling for somatization, women still had worse physical function, functional capacity, and symptom burden than men. Independent of cardiac disease severity and age, women with AF had significantly more impaired QOL than men, specifically on domains related to physical rather than emotional functioning. Personality attributes may have a role in influencing QOL outcomes.

Abstract
The short- and long-term mortality of patients greater than 75 years of age with acute myocardial infarction is still very high. These patients have been excluded from most randomized controlled trials designed to test interventions directed to improve the outcome of acute myocardial infarction. Contrary to young-old patients (65-74 years) in whom the benefit obtained with these interventions is even greater than that observed in younger patients, there is a lack of information concerning the optimal treatment of acute myocardial infarction in the oldest patients. Research specifically directed to assess the optimal reperfusion strategy and coadjuvant therapies in patients greater than 75 years old is critically important. The causes for such high mortality are still poorly understood. Several clinical observations suggest that old patients with acute myocardial infarction have specific pathophysiologic behaviors. As the knowledge of the mechanisms of disease is, in clinical practice, the basis of therapy development, clinical and basic research designed to elucidate the specific pathophysiological mechanisms and causes of the high mortality in the oldest patients with acute myocardial infarction should be regarded as a priority in geriatric cardiovascular research.

Abstract
In every year since 1984, cardiovascular disease has claimed the lives of more women than men. Data from randomized trials indicate that gender contributes to increased mortality after myocardial infarction independent of other risk factors, but additional confounding variables cannot be discounted. Data from registry databases indicate that women are less likely to receive medically proven therapies for myocardial infarction. Women experience more vague symptoms, which may account for underuse of effective therapies. In addition, they may benefit less from thrombolytic therapy than men. Increased use of thrombolytic therapy has resulted in a continued decrease in cardiovascular deaths for men, but not for women. It is unclear if this disparity is a result of inequitable access to therapy or decreased efficacy of these agents in women.

Abstract
Older people with congestive heart failure associated with acute myocardial infarction should be treated with loop diuretic therapy. Class I indications for the use of early intravenous beta blockade in patients with acute myocardial infarction are patients without a contraindication to beta blockers who can be treated within 12 hours of onset of myocardial infarction; patients with continuing or recurrent ischemic pain; and patients with tachyarrythmias, such as atrial fibrillation with a rapid ventricular rate. Class I indications for the use of angiotensin-converting enzyme inhibitors during acute myocardial infarction are (1) patients within the first 24 hours of onset of a suspected acute myocardial infarction with ST segment elevation in two or more anterior precordial leads or with clinical heart failure in the absence of significant hypotension or contraindications to the use of angiotensin-converting enzyme inhibitors, (2) patients with myocardial infarction and a left ventricular ejection fraction of less then 40%, (3) and patients with clinical heart failure on the basis of systolic pump dysfunction during and after convalescence from acute myocardial infarction. No class I indications exist for using calcium channel blockers or magnesium during acute myocardial infarction.

Abstract
BACKGROUND Previous studies have suggested that women with acute myocardial infarction receive less aggressive therapy than men. We used data from the Cooperative Cardiovascular Project to determine whether women and men who were ideal candidates for therapy after acute myocardial infarction were treated differently. METHODS Information was abstracted from the charts of 138,956 Medicare beneficiaries (49 percent of them women) who had an acute myocardial infarction in 1994 or 1995. Multivariate analysis was used to assess differences between women and men in the medications administered, the procedures used, the assignment of do-not-resuscitate status, and 30-day mortality. RESULTS Among ideal candidates for therapy, women in all age groups were less likely to undergo diagnostic catheterization than men. The difference was especially pronounced among older women; for a woman 85 years of age or older, the adjusted relative risk was 0.75 (95 percent confidence interval, 0.68 to 0.83). Women were somewhat less likely than men to receive thrombolytic therapy within 60 minutes (adjusted relative risk, 0.93; 95 percent confidence interval, 0.90 to 0.96) or to receive aspirin within 24 hours after arrival at the hospital (adjusted relative risk, 0.96; 95 percent confidence interval, 0.95 to 0.97), but they were equally likely to receive beta-blockers (adjusted relative risk, 0.99; 95 percent confidence interval, 0.95 to 1.03) and somewhat more likely to receive angiotensin-converting-enzyme inhibitors (adjusted relative risk, 1.05; 95 percent confidence interval, 1.02 to 1.08). Women were more likely than men to have a do-not-resuscitate order in their records (adjusted relative risk, 1.26; 95 percent confidence interval, 1.22 to 1.29). After adjustment, women and men had similar 30-day mortality rates (hazard ratio, 1.02; 95 percent confidence interval, 0.99 to 1.04). CONCLUSIONS As compared with men, women receive somewhat less aggressive treatment during the early management of acute myocardial infarction. However, many of these differences are small, and there is no apparent effect on early mortality.

Abstract
The progressive aging of the population is associated with an increase in the proportion of very old patients (greater than 75 years) hospitalized with acute myocardial infarction. The lack of evidence regarding the efficacy of most therapeutic interventions for acute myocardial infarction in these patients is leading to a significant degree of uncertainty in the cardiology community with respect to their optimal management. When aggressive treatment (defined as a therapeutic strategy designed to obtain and maintain a patent infarct-related coronary artery at an early moment) of acute myocardial infarction is considered in very old patients, three main questions should be addressed: why should we treat? Whom should we treat? And how should we treat? To answer these questions, the authors reviewed the data available in the literature as well as new data from the PPRIMM75 (Pronóstico del PRimer Infarto de Miocardio en Mayores de 75 aÃ+/-os) Registry, a large, prospective database of patients aged 75 years or older, admitted to a single coronary care unit in Madrid, Spain, for their first acute myocardial infarction during the last decade.

Abstract
OBJECTIVES In this study we evaluate gender differences in affective adaptation and health perception in patients 6 months after stent implantation. BACKGROUND Assessment of gender-specific behavioral strategies to cope with serious cardiac disease conditions has not been given much attention until now. Preliminary data suggest greater impairments in female patients, which might be of clinical relevance. METHODS Three hundred seventeen patients were eligible for the 6-month follow-up investigation, 78 (24.6%) of whom were women. The women were significantly older but did not differ from men in their cardiac risk features and treatment procedures. There were no gender differences in prevalence of hypertension, hypercholesterolemia, and family history. Men had a significantly higher prevalence of smoking than women, whereas women had a significantly higher prevalence of diabetes than men. A structured interview and a standardized psychodiagnostic assessment was carried out, which covered domains of affective dysfunction (depression, anxiety, intrusion, and avoidance), vegetative symptoms (sleeping disorders), and parameters of negative health perception. RESULTS There were no significant gender differences in the prevalence of depressive symptoms. Women exhibited higher mean values of anxiety than men, which did not reach significance. Sleeping disorders were significantly more prevalent in women. The absolute level of being distressed by intrusive thoughts and avoidance behavior related to the severe underlying disease process was low in the total group of patients examined. Measurable gender differences did not emerge. Fifty-one (16.5%) patients exhibited pessimistic anticipation of dire consequences and severe signs of negative health perception (NHP group). There was a trend, although not statistically significant, toward more women being in the NHP group. The distribution of cardiac risk factors, however, was completely balanced in the NHP(+) and NHP(-) patient groups. Objective somatic cardiac disease parameters did not account for the negative health perception. NHP was, however, associated with significantly more prestent angina pectoris (p < 0.040) and poststent angina pectoris (p < 0.0001). High levels of anxiety, depression, and of disturbed sleep also led to a sharp separation between patients with high degrees of an anticipated incapacitation due to the disease process. Univariate regression analysis suggested an effect of female gender on the occurrence of NHP (odds ratio 1. 70; 95% CI 0.88 to 3.25), which was of borderline significance. Control for confounders in a multiple regression model, however, eliminated the gender effect (odds ratio 1.04, 95% CI 0.48 to 2.23). Poststent chest pain (odds ratio 7.75, 95% CI 3.28 to 18.32) and sleeping disorders (odds ratio 1.32, 95% CI 1.16 to 1.51) were identified as the most powerful confounders of the gender-NHP association. CONCLUSION Contrary to expectation, women were not per se more distressed than men in all areas of adaptation of the midterm course after stent implantation, although the higher levels of anxiety and sleeping disorders in women deserve attention. A considerable proportion of patients exhibited a pessimistic disease perspective independent of their somatic status, which was associated with affective morbidity. The tendency toward more negative health perception in women may be due to their more frequent occurrence of chest pain and sleeping disorders.

Abstract
Historically, risk stratification for survivors of acute myocardial infarction (AMI) has centered on 3 principles: assessment of left ventricular function, detection of residual myocardial ischemia, and estimation of the risk for sudden cardiac death. Although these factors still have important prognostic implications for these patients, our ability to predict adverse cardiac events has significantly improved over the last several years. Recent studies have identified powerful predictors of adverse cardiac events available from the patient history, physical examination, initial electrocardiogram, and blood testing early in the evaluation of patients with AMI. Numerous studies performed in patients receiving early reperfusion therapy with either thrombolysis or primary angioplasty have emphasized the importance of a patent infarct related artery for long-term survival. The predictive value of a variety of noninvasive and invasive tests to predict myocardial electrical instability have been under active investigation in patients receiving early reperfusion therapy. The current understanding of the clinically important predictors of clinical outcomes in survivors of AMI is reviewed in this article.

Abstract
In the recent years, new possibilities have emerged in the diagnosis and management of acute myocardial infarction with ST segment elevation and its complications. Moreover, a deep transformation has taken place in the health care system organization, particularly in aspects related to care of patients presenting non-traumatic chest pain, both in pre-hospital and hospital areas. All these issues warrant a consensus document in Spain dealing with the role that these important changes should play in the whole management of myocardial infarction patients. This document revises and updates all the main clinical issues of acute myocardial infarction patients from the moment they contact with the health care system outside the hospital until they return home, after staying at the coronary care unit and the general hospitalization ward. All those aspects are considered not only in the uncomplicated myocardial infarction but also in the complicated one. This review also includes a set of recommendations on structural and organisational aspects, mainly referred to the prehospital and emergency levels.

Abstract
Age and female gender have been associated with poor prognosis in acute myocardial infarction (AMI). Data currently available about the prognostic significance of gender in AMI might well have led to inappropriate/incomplete conclusions. A multicenter, prospective study on 1239 patients with AMI was conducted. Clinical characteristics, complications during the acute phase and one-year follow-up were monitored. Women constituted 24.1% of all patients. Female patients were older with more prevalence of diabetes, hypertension, and previous congestive heart failure. Compared with men, the following complications were more frequently found in women: heart failure, 43% vs. 22% (p < 0.001); reinfarction, 5% vs. 2% (p < 0.05); use of pacemaker, 7% vs. 4% (p < 0.05). Women had higher mortality: early, during the first 24 hours post-admission, 10.7 vs. 3.1%; in-hospital, 23% vs. 8.1%; and 1-year, 33.7% vs. 16% (p < 0.001 for all the 3 cases of mortality). In the age-groups considered (<65, 65-74, and > or =75 years), 1-year mortality increased exponentially with ageing in men: 7.8%, 21.3%, and 38.9%, whereas in women the figures were: 15.3%, 41.5%, and 38.8%. Multivariate analysis showed that, among other variables, age and female gender had independent prognostic value for in-hospital mortality whereas gender lost its prognostic significantly for 1-year mortality. Multivariate analysis restricted to those patients aged over 75 years showed that age but not gender had independent prognostic value. In conclusion, age and female sex have independent prognostic value for predicting mortality in patients with AMI. Mortality increases exponentially with ageing in men whereas it stabilises in the case of women over 65 years. Female gender loses its independent value for predicting mortality in patients over 75 years.

Abstract
BACKGROUND There is conflicting information about whether short-term mortality after myocardial infarction is higher among women than among men after adjustment for age and other prognostic factors. We hypothesized that younger, but not older, women have higher mortality rates during hospitalization than their male peers. METHODS We analyzed data on 384,878 patients (155,565 women and 229,313 men) who were 30 to 89 years of age and who had been enrolled in the National Registry of Myocardial Infarction 2 between June 1994 and January 1998. Patients who had been transferred from or to other hospitals were excluded. RESULTS The overall mortality rate during hospitalization was 16.7 percent among the women and 11.5 percent among the men. Sex-based differences in the rates varied according to age. Among patients less than 50 years of age, the mortality rate for the women was more than twice that for the men. The difference in the rates decreased with increasing age and was no longer significant after the age of 74 (P< 0.001 for the interaction between sex and age). Logistic-regression analysis showed that the odds of death were 11.1 percent greater for women than for men with every five-year decrease in age (95 percent confidence interval, 10.1 to 12.1 percent). Differences in medical history, the clinical severity of the infarction, and early management accounted for only about one third of the difference in the risk. After adjustment for these factors, women still had a higher risk of death for every five years of decreasing age (increase in the odds of death, 7.0 percent; 95 percent confidence interval, 5.9 to 8.1 percent). CONCLUSIONS After myocardial infarction, younger women, but not older women, have higher rates of death during hospitalization than men of the same age. The younger the age of the patients, the higher the risk of death among women relative to men. Younger women with myocardial infarction represent a high-risk group deserving of special study.

Abstract
A prospective study of acute myocardial infarction was carried out in 1239 patients in order to assess both the prognostic significance of diabetes mellitus and the clinical characteristics associated with age and gender. Diabetes mellitus (DM) was found in 386 cases, often associated with old age, female gender, and more prevalent history of angina, heart failure, and hypertension. DM patients were admitted later and they were less likely to receive thrombolytic therapy, 47.9 vs. 58.1% (P<0.001). Complications more often associated with DM were: heart failure, 45 vs. 24.5% (P<0.01), and early, in-hospital and 1-year mortalities, 7.2 vs. 3.9% (P<0.05), 17.6 vs. 9.1% (P<0.001), and 29.2 vs. 16.2% (P<0.001), respectively. Compared with diabetic men, diabetic women were older and had a more prevalent history of hypertension and congestive heart failure. Diabetic women also had a higher rate of heart failure during hospitalisation, and of mortality, than diabetic men: early: 11.7 vs. 4.5% (P<0.01); in-hospital: 29.6 vs. 10.3% (P<0.001); and 1-year: 42.7 vs. 21.1% (P>0.001). DM was not selected by the multivariate analysis as a variable with independent prognostic value for mortality. In separate multivariate analysis for diabetic and non-diabetic patients, female gender had independent prognostic value for mortality only in the case of the diabetic population.

Abstract
To assess the current incidence and meaning of left bundle-branch block associated with acute myocardial infarction we studied 1,239 patients consecutively admitted in three hospitals. Left bundle branch block was present in 42 cases (3.3%). Compared to the patients without left bundle-branch block, those with left bundle-branch block were older (70 +/- 8.8 versus 63.9 +/- 11.4 years; p < 0.001), and had a more prevalent history of diabetes, angina, myocardial infarction and heart failure. Left bundle-branch block was associated more frequently with female gender and poor left ventricular ejection fraction. Patients with left bundle branch block were admitted with a longer interval from the onset of the symptoms (7.8 +/- 6.3 versus 5.4 +/- 6.7 hours; p < 0.01) and received in a lesser rate thrombolytics agents (21% versus 56%; p < 0.001), than those without left bundle-branch block. Complications significatively associated with left bundle-branch block were: complete AV block; heart failure and one-year mortality (40.4% versus 19.5%, p < 0.01). Female gender, age and heart failure were independent predictors of mortality whereas left bundle-branch block was not. In conclusion, current incidence of left bundle-branch block in acute myocardial infarction is lower than that referred in the pre-thrombolytic era. Left bundle-branch block is accompanied by a low rate of thrombolysis, whereas a higher mortality rate of these patients seems to depend on their clinical characteristics.

Abstract
OBJECTIVES The prognostic importance of gender in hospitalized patients has been poorly studied. The current study compared in-hospital death rates between men and women after adjusting for severity of illness. DESIGN Retrospective cohort study. PATIENTS 89,793 eligible patients with 6 common nonsurgical diagnoses who were discharged from 30 hospitals in Northeast Ohio in 1991 to 1993. METHODS Admission severity of illness (ie, predicted risk of death) was calculated using multivariable models that were based on data abstracted from patients' clinical records (ROC curve areas, 0.83-0.90). In hospital death rates were then adjusted for predicted risks of death and other covariates using logistic regression analysis. RESULTS Adjusted odds of death were higher (P < 0.05) in men, compared with women, for 4 diagnoses (stroke [OR, 1.60]; obstructive airway disease [OR, 1.38]; gastrointestinal hemorrhage [OR 1.32]; pneumonia [OR, 1.18]) and similar for two diagnoses (congestive heart failure [OR, 1.12]; and acute myocardial infarction [OR, 0.97]). These differences were somewhat attenuated by excluding patients discharged to skilled nursing facilities or other hospitals from analysis; nonetheless, the odds of death in men remained higher for 3 diagnoses. CONCLUSIONS The findings indicate that inhospital death rates are generally higher in men than in women, after adjusting for severity of illness. In addition, the risk of in-hospital death in men and women was influenced by diagnosis. These differences may reflect gender-related variation in the utilization of hospital services, the effectiveness of care, over- or underestimation of severity of illness, or biological differences in men and women.

Abstract
OBJECTIVE To examine the effect of gender differences among older adults hospitalized for an acute myocardial infarction (AMI) on subsequent health outcomes. DESIGN Secondary analysis of the Longitudinal Study on Aging. Data from baseline interviews (1984) and three biennial (1986, 1988, and 1990) re-interviews were linked to Medicare hospitalization and National Death Index records for 1984-1991. PARTICIPANTS A total of 6071 community-dwelling adults aged 70 years or older at baseline. METHODS Pooled and stratified multivariable models were used to examine gender differences in the independent effects of being hospitalized for an AMI on all-cause mortality, the risk and volume of subsequent hospitalization, and increases in the number of functional limitations. Two comparison groups were used. RESULTS Three hundred fifty-seven AMI cases (6%; 172 women and 185 men) were compared with 3976 hospitalized controls and 1738 nonhospitalized controls. The risk of all-cause mortality for AMI cases was greater than that for either hospitalized controls or nonhospitalized controls (referent), and this increased risk was significantly (P < .001) stronger for women (adjusted hazards ratio (AHR) = 14.24, 95%CI = 10.99, 18.46) than for men (AHR = 9.91, 95%CI = 7.75, 12.67). Overall, AMI cases were also more likely to be hospitalized subsequently than the hospitalized controls (referent; adjusted odds ratio (AOR) = 1.47, 95%CI = 1.17, 1.85), although in the stratified analysis this association held for men (AOR = 1.73, 95%CI = 1.25, 2.41) but not for women (AOR = 1.25, 95%CI = .90, 1.73). Among those subsequently hospitalized, both women and men AMI cases consumed more hospital resources than the hospitalized controls, and there were gender differences suggesting that the effects on total charges and length of stay were greater for women than for men with AMI. Finally, although the AMI cases had greater adjusted mean increases in the number of instrumental activities of daily living limitations and lower body limitations than the nonhospitalized controls, they were no worse off than the hospitalized controls, and there were no gender differences in those effects. CONCLUSION Relative to the appropriate comparison groups, hospitalization for an AMI increases the risk of death and the total costs and lengths of stay of subsequent hospitalizations for women more than for men. Therefore, increased primary prevention, diagnosis, and treatment efforts should be directed toward women.

Abstract
The majority of patients presenting with acute coronary disease or undergoing coronary revascularization procedures are older than age 65. Disability rates are very high in these patient populations, particularly in women, the older-old, and patients with clinical manifestations of angina pectoris or chronic heart failure. The presence of mental depression is also an important determinant of poor physical functioning. Cardiac rehabilitation has been demonstrated to safely increase aerobic capacity, muscular strength, and endurance in older coronary populations.

Abstract
Although considerable information is available regarding the prognosis after acute myocardial infarction (AMI) in Western populations, little is known about the fate of Japanese subjects after AMI. The purpose of this study was to assess short-term mortality and factors influencing it after AMI in Japan. From April 1993 to December 1995, 1,014 patients with AMI from 41 hospitals in Yamagata Prefecture were registered by cardiologists for the prospective survey. Among patients who died within 28 days after the onset of AMI, immediate causes of death were examined and the clinical profiles of these subjects were compared with those of patients that survived. Early death occurred in 184 patients (short-term mortality 18%). Patients who died were significantly older than survivors (76.1+/-9.4 vs 67.6+/-11.8 years, p<0.01). They were also more likely to be women (50% vs 31%, p<0.01), to have had hypertension (64% vs 54%, p<0.05), diabetes mellitus (29% vs 20%, p<0.02), prior MI (17% vs 12%, p<0.05), or Killip class III or IV disease (63% vs 15%, p<0.01), and were significantly less likely to be current smokers (26% vs 45%, p<0.01) or to have been treated with reperfusion therapy (27% vs 63%, p<0.01). Multivariate logistic analysis demonstrated that independent predictors of early death were Killip class III or IV and advanced age. Reperfusion therapy was a negative predictor of death. Patients who died had arrived at hospital earlier than patients who survived. Mortality as a result of heart failure, cardiac rupture, or arrhythmia fell exponentially after the onset of AMI. Thus, the predictors of short-term mortality were similar to those reported in Western populations. More deaths occurred just after the onset of disease, suggesting that early therapy is important in reducing short-term mortality.

Abstract
Several studies have indicated that women sustaining a myocardial infarction have a higher unadjusted short-term (i.e., in-hospital or 30-day) mortality than men. The advanced age of women at the time of presentation appears to be the major factor contributing to their worse prognosis relative to men. Controlling for age eliminates the association between female gender and increased mortality in most, but not all studies. This article reviews the data on age and other factors that might explain why women with a myocardial infarction fare worse then men.

Abstract
BACKGROUND After myocardial infarction, women have higher rates of recurrent coronary events than men. This is caused, at least in part, by a higher prevalence of obesity-related coronary risk factors such as hyperlipidemia, hypertension, sedentary lifestyle, insulin resistance, and diabetes. We studied the relationship between measures of body fat distribution, body composition, aerobic fitness, and dietary intake and several coronary risk factors including lipids, glucose, and insulin levels. METHODS The study population included 20 women > 60 years of age with recently diagnosed coronary heart disease and a comparison group of 50 healthy women with low-risk coronary risk profiles. Dependent variables included lipid subfractions (fasting, triglycerides, high-density lipoprotein [HDL] cholesterol, and low-density lipoprotein [LDL] cholesterol), glucose levels, and serum insulin levels. RESULTS Waist-to-hip ratio (WHR) was the best predictor of serum triglyceride levels (r = .65, P = .002), HDL cholesterol level (r = .46, P = .05), and fasting serum insulin levels (r = .76, P < .001) whereas peak oxygen consumption (Peak VO2) was the best predictor of LDL cholesterol (r = .73, P < .001). In a combined population of the 20 coronary patients and 50 healthy age-matched controls, WHR remained the best predictor of serum triglyceride levels (r = .57, P < .001) and insulin levels (r = .63, P < .001) and Peak V02 was the best predictor of HDL (r = .40, P < .001) and LDL cholesterol (r = .57, P = .004). CONCLUSIONS Body fat distribution and peak aerobic fitness, both modifiable factors, are significant predictors of risk factors for second coronary events in older female coronary patients.
