- Background A routine invasive (RI) strategy in non-ST-segment elevation acute coronary syndromes (NSTE ACS) has been associated with better outcome compared with a selective invasive (SI) strategy in men, but results in women have yielded disparate results. The aim of this study was to assess gender differences in long-term outcome with an SI compared with an RI strategy in NSTE ACS. Methods Individual patient data were obtained from the FRISC II trial, ICTUS trial, and RITA 3 trial for a collaborative meta-analysis. Results Men treated with an RI strategy had significantly lower rate of the primary outcome 5-year cardiovascular (CV) death/myocardial infarction (MI) compared with men treated with an SI strategy (15.6% vs 19.8%, P = .001); risk-adjusted hazards ratio (HR) 0.73 (95% CI 0.63-0.86). In contrast, there was little impact of an RI compared with an SI strategy on the primary outcome among women (16.5% vs 15.1%, P = .324); risk-adjusted HR 1.13 (95% CI 0.89-1.43), interaction P = .01. For the individual components of the primary outcome, a similar pattern was seen with lower rate of MI (adjusted HR 0.69, 95% CI 0.57-0.83) and CV death (adjusted HR 0.71, 95% CI 0.56-0.89) in men but without obvious difference in women in MI (adjusted HR 1.13, 95% CI 0.85-1.50) or CV death (adjusted HR 0.97, 95% CI 0.68-1.39). Conclusions In this meta-analysis comparing an SI and RI strategy, benefit from an RI strategy during long-term follow-up was confirmed in men. Conversely, in women, there was no evidence of benefit.

- Acute Coronary Syndromes are the most frequent manifestations of coronary heart disease (CHD). Gender differences in treatment intensity, including differences in level of care, have been reported. Also differences in benefit from certain treatments, especially invasive treatment, have been discussed. Finally, differences in outcome between men and women have been proposed. Results have been inconsistent, partly depending on if and how adjustment for differences in background characteristics has been made.

- Aims To assess gender differences in outcome with an early invasive or non-invasive strategy in patients with non-ST-elevation acute coronary syndromes (NSTE ACS). less thanbrgreater than less thanbrgreater thanMethods and results We included 46 455 patients [14 819 women (32%) and 31 636 men (68%)] from the SWEDEHEART register, with NSTE ACS, between 2000 and 2006, and followed them for 1 year. In the non-invasive strategy arm, the relative risk (RR) of death was (women vs. men) 1.02 [95% confidence interval (CI), 0.94-1.11] and in the invasive strategy arm 1.12 (95% CI, 0.96-1.29). After adjustment for baseline differences between the genders, with propensity score and discharge medication, there was a similar trend towards better outcome among women in both the early non-invasive cohort [RR 0.90 (95% CI, 0.82-0.99)] and the early invasive cohort [RR 0.90 (95% CI, 0.76-1.06)], although it did not reach statistical significance in the early invasive cohort. Results were similar with the combined endpoint death/myocardial infarction. An early invasive treatment was associated with a marked, and similar, mortality reduction in women [RR 0.46 (95% CI, 0.38-0.55)] and men [RR 0.45 (95% CI, 0.40-0.52)], without interaction with gender. less thanbrgreater than less thanbrgreater thanConclusion In this large cohort of patients with NSTE ACS, reflecting real-life management, women and men had similar and better outcome associated with an invasive strategy.

- BACKGROUND: For the large population of elderly patients with cardiovascular disease, it is crucial to identify clinically relevant measures of biological age and their contribution to risk. Frailty is denoting decreased physiological reserves and increased vulnerability. We analysed the manner in which the variable frailty is associated with 1-year outcomes for elderly non-ST-segment elevation myocardial infarction (NSTEMI) patients. METHODS AND RESULTS: Patients aged 75 years or older, with diagnosed NSTEMI were included at three centres, and clinical data including judgment of frailty were collected prospectively. Frailty was defined according to the Canadian Study of Health and Aging Clinical Frailty Scale. Of 307 patients, 149 (48.5%) were considered frail. By Cox regression analyses, frailty was found to be independently associated with 1-year mortality after adjusting for cardiovascular risk and comorbid conditions (hazard ratio 4.3, 95% CI 2.4-7.8). The time to the first event was significantly shorter for frail patients than for nonfrail (34 days, 95% CI 10-58, p = 0.005). CONCLUSIONS: Frailty is strongly and independently associated with 1-year mortality. The combined use of frailty and comorbidity may constitute an important risk prediction concept in regard to cardiovascular patients with complex needs.

- Background: For the large and growing population of elderly patients with cardiovascular disease, it is important to identify clinically relevant measures of biological age and their contribution to risk. Frailty is an emerging concept in medicine denoting increased vulnerability and decreased physiological reserves. We analyzed the manner in which the variable frailty predicts short-term outcomes for elderly non-ST-segment elevation myocardial infarction patients. Methods and results: Patients aged ≥ 75 years, with diagnosed non-ST-segment elevation myocardial infarction were included at 3 centers, and clinical data including judgment of frailty were collected prospectively. Frailty was defined according to the Canadian Study of Health and Aging Clinical Frailty Scale. The impact of the comorbid conditions on risk was quantified by the coronary artery disease-specific index. Of 307 patients, 149 (48.5%) were considered frail. By multiple logistic regression, frailty was found to be strongly and independently associated with risk for the primary composite outcome (death from any cause, myocardial reinfarction, revascularization due to ischemia, hospitalization for any cause, major bleeding, stroke/transient ischemic attack, and need for dialysis up to 1 month after inclusion) (odds ratio, 2.2; 95% confidence interval, 1.3-3.7) in-hospital mortality (odds ratio, 4.6; 95% confidence interval, 1.3-16.8), and 1-month mortality (odds ratio, 4.7; 95% confidence interval, 1.7-13.0). Conclusions: Frailty is strongly and independently associated with in-hospital mortality, 1-month mortality, prolonged hospital care, and the primary composite outcome. The combined use of frailty and comorbidity may constitute an ultimate risk prediciton concept in regard to cardiovascular patients with complex needs.

- Objective To evaluate if female gender is associated with renal insufficiency in patients with ST-elevation myocardial infarction (STEMI) and if there is a gender difference in the prognostic importance of renal insufficiency in STEMI. Design Single-centre observational study. Setting One tertiary cardiac centre. Patients All consecutive patients with STEMI planned for primary percutaneous coronary intervention in one Swedish county in 2005 (98 women and 176 men). Main outcome measures Logistic regression analyses were conducted to evaluate the predictors of renal insufficiency, associations between estimated glomerular filtration rate (eGFR) and outcome in each gender and a possible interaction between gender and eGFR regarding outcome. Results Renal insufficiency was defined as eGFR less than 60 ml/min per 1.73 m(2). 67% of women had renal insufficiency compared with 26% of men, OR 5.06 (95% CI 2.66 to 9.59) after multivariable adjustment. In women each 10 ml/min per 1.73 m 2 increment of eGFR was associated with a 63% risk reduction for 1-year mortality, OR 0.37 (95% CI 0.15 to 0.89). No such association was found in men, OR 1.05 (95% CI 0.63 to 1.76). A trend towards a significant interaction between gender and eGFR regarding 1-year mortality was found, OR 2.05 (95% CI 0.93 to 4.50). Conclusions A considerable gender difference in the prevalence of renal insufficiency in STEMI was found and renal insufficiency seemed to be a more important prognostic marker in women. These results are important as previous STEMI studies have shown higher multivariable adjusted mortality in women than in men but renal function has seldom been taken into consideration.

- Objectives The purpose of this study was to conduct a meta-analysis to examine an invasive or conservative strategy in diabetic versus nondiabetic patients. Background Diabetic patients are at increased risk of cardiovascular events after an acute coronary syndrome, yet it remains unknown whether they derive enhanced benefit from an invasive strategy.Methods Randomized trials comparing an invasive versus conservative treatment strategy were identified. The prevalence of cardiovascular events through 12 months was reported for each trial, stratified by diabetes mellitus status and randomized treatment strategy. Relative risk (RR) ratios and absolute risk reductions were combined using random-effects models.Results Data were combined across 9 trials comprising 9,904 subjects of whom 1,789 (18.1%) had diabetes mellitus. The RRs for death, nonfatal myocardial infarction (MI), or rehospitalization with an acute coronary syndrome for an invasive versus conservative strategy were similar between diabetic patients (RR: 0.87; 95% confidence interval [CI]: 0.73 to 1.03) and nondiabetic patients (RR: 0.86; 95% CI: 0.70 to 1.06; p interaction = 0.83). An invasive strategy reduced nonfatal MI in diabetic patients (RR: 0.71; 95% CI: 0.55 to 0.92), but not in nondiabetic patients (RR: 0.98; 95% CI: 0.74 to 1.29; p interaction = 0.09). The absolute risk reduction in MI with an invasive strategy was greater in diabetic than nondiabetic patients (absolute risk reduction: 3.7% vs. 0.1%; p interaction = 0.02). There were no differences in death or stroke between groups (p interactions 0.68 and 0.20, respectively).Conclusions An early invasive strategy yielded similar RR reductions in overall cardiovascular events in diabetic and nondiabetic patients. However, an invasive strategy appeared to reduce recurrent nonfatal MI to a greater extent in diabetic patients. These data support the updated guidelines that recommend an invasive strategy for patients with diabetes mellitus and non-ST-segment elevation acute coronary syndromes.
