Sex-based differences in outcomes after percutaneous coronary intervention for acute myocardial infarction: a report from TRANSLATE-ACS.

ABSTRACT: Data regarding sex-based outcomes after percutaneous coronary intervention (PCI) for myocardial infarction are mixed. We sought to examine whether sex differences in outcomes exist in contemporary practice.We examined acute myocardial infarction patients undergoing PCI between April 2010 and October 2012 at 210 US hospitals participating in the Treatment with Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events after Acute Coronary Syndrome (TRANSLATE-ACS) observational study. Outcomes included 1-year risk of major adverse cardiac events and bleeding according to Global Utilization of Strategies To Open Occluded Arteries (GUSTO) and Bleeding Academic Research Consortium (BARC) definitions. Among 6218 patients, 27.5% (n=1712) were female. Compared with men, women were older, had more comorbidities, and had lower functional status. Use of multivessel PCI and drug-eluting stents was similar between sexes, while women received less prasugrel. Unadjusted cumulative incidence of 1-year major adverse cardiac events was higher for women than for men (15.7% versus 13.6%, P=0.02), but female sex was no longer associated with higher incidence of major adverse cardiac events after multivariable adjustment (hazard ratio 0.98, 95% CI 0.83 to 1.15). Female sex was associated with higher risks of post-PCI GUSTO bleeding (9.1% versus 5.7%, P<0.0001) and postdischarge BARC bleeding (39.6% versus 27.9%, P<0.0001). Differences persisted after adjustment (GUSTO: hazard ratio 1.32, 95% CI 1.06 to 1.64; BARC: incidence rate ratio 1.42, 95% CI 1.27 to 1.56).Female and male myocardial infarction patients undergoing PCI differ regarding demographic, clinical, and treatment profiles. These differences appear to explain the higher observed major adverse cardiac event rate but not higher adjusted bleeding risk for women versus men.

Project description:Among patients with acute myocardial infarction (MI) who have multivessel disease, it is unclear if multivessel percutaneous coronary intervention (PCI) improves clinical and quality-of-life outcomes compared with culprit-only intervention. We sought to compare clinical and quality-of-life outcomes between multivessel and culprit-only PCI.Among 6061 patients with acute MI who have multivessel disease in the TRANSLATE-ACS (Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome) study, we used inverse probability-weighted propensity adjustment to study the associations between multivessel and culprit-only intervention during the index PCI and major adverse cardiovascular events, unplanned all-cause readmission, and angina frequency at 6 weeks and 1 year. Multivessel PCI was performed in 1208 (20%) of patients with MI who had multivessel disease. Relative to the culprit-only intervention, patients receiving multivessel PCI were similarly aged and more likely to be seen with non-ST-segment elevation MI or cardiogenic shock. At 6 weeks, the initial multivessel PCI strategy was associated with lower major adverse cardiovascular events and unplanned readmission risks, whereas angina frequency was not significantly different between multivessel and culprit-only PCI. At 1 year, major adverse cardiovascular event risk was persistently lower in the multivessel PCI group (adjusted hazard ratio, 0.84; 95% confidence interval, 0.72-0.99), whereas long-term readmission risk (adjusted hazard ratio, 0.94; 95% confidence interval, 0.84-1.04) and angina frequency were similar between groups (adjusted odds ratio, 1.01; 95% confidence interval, 0.82-1.24). Similar associations were seen when patients with ST-segment elevation MI and non-ST-segment elevation MI were examined separately.Among patients with acute MI who have multivessel disease, multivessel PCI was associated with lower risk of all-cause readmission at 6 weeks and lower risk of major adverse cardiovascular events at 6 weeks and 1 year. However, similar short- and long-term angina frequencies were noted.

Project description:Background Hospitalization for acute myocardial infarction (MI) in the United States is both common and expensive, but those features alone provide little insight into cost-saving opportunities. Methods and Results To understand the cost drivers during hospitalization for acute MI and in the following year, we prospectively studied 11 969 patients with acute MI undergoing percutaneous coronary intervention at 233 US hospitals (2010-2013) from the TRANSLATE-ACS (Treatment With ADP Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome) registry. Baseline costs were collected in a random subset (n=4619 patients, 54% ST-segment-elevation MI [STEMI]), while follow-up costs out to 1 year were collected for all patients. The mean index length of stay was 3.1 days (for both STEMI and non-STEMI) and mean intensive care unit length of stay was 1.2 days (1.4 days for STEMI and 1.0 days for non-STEMI). Index hospital costs averaged $18 931 ($19 327 for STEMI, $18 465 for non-STEMI), with 45% catheterization laboratory-related and 20% attributable to postprocedure hospital stay. Patient factors, including severity of illness and extent of coronary disease, and hospital characteristics, including for profit status and geographic region, identified significant variations in cost. Intensive care was used for 53% of non-STEMI and increased costs by $3282. Postdischarge 1-year costs averaged $8037, and 48% of patients were rehospitalized (half within 2 months and 57% with a cardiovascular diagnosis). Conclusions While much of the cost of patients with acute MI treated with percutaneous coronary intervention is probably not modifiable by the care team, cost reductions are still possible through quality-preserving practice efficiencies, such as need-based use rather than routine use of intensive care unit for patients with stable non-STEMI.

Project description:Infective endocarditis (IE) is still a condition with high mortality and morbidity, especially in the elderly, and in patients with prosthetic valves. The concept of "time-to-therapy" plays a key role for the prompt management of IE and related complications, and the currently available multimodality imaging may play a key role in this setting. Myocardial ischemia due to extrinsic coronary compression from an aortic abscess is an extremely rare condition where the optimal therapeutic strategy has not been defined yet. We present herein the first case of a patient with ST elevation myocardial infarction caused by an aortic root abscess treated with percutaneous stent implantation.An 82-year-old woman with a history of atrial fibrillation, chronic renal failure, anemia and a bioprosthetic aortic valve replacement performed in 2014, was admitted to hospital with profound asthenia and a pyrexia of unknown origin. Because of high clinical suspicion of endocarditis, a trans-esophageal echocardiogram was performed. Empirical broad-spectrum antimicrobial therapy was initiated, followed by targeted treatment based on the results of blood cultures (Staphylococcus aureus). The echocardiogram did not show vegetations and the patient was managed conservatively. She suddenly deteriorated, due to an acute coronary syndrome (ACS) with anterior ST segment elevation. An urgent angiogram was performed, and extrinsic compression of the left coronary system, due to an aortic root abscess, was suspected. After discussion with the surgical team, percutaneous revascularization was attempted, aiming to restore satisfactory hemodynamics, in order to plan surgery. Unfortunately, the patient rapidly developed cardiogenic shock, with multi organ failure, and died in less than 24 h.Patients with fever, and significant risk factors for endocarditis, who develop ACS, need a prompt diagnostic work up, including trans-esophageal echocardiography. At present, the specific timing of echocardiographic follow-up and surgical intervention is still a matter of debate, and our case aims to highlight the importance of this aspect in the management of endocarditis, in order to avoid severe complications that adversely affect patient prognosis.

Project description:Background Sex differences in health status outcomes after percutaneous coronary intervention among patients without acute myocardial infarction are not well described. Methods and Results A total of 2237 patients (33.4% women) without acute myocardial infarction undergoing percutaneous coronary intervention were enrolled from 39 Chinese tertiary hospitals in the PEACE (China Patient-centered Evaluative Assessment of Cardiac Events) prospective percutaneous coronary intervention study. Data were collected immediately before and 1 year following percutaneous coronary intervention. Health status was measured using the disease-specific Seattle Angina Questionnaire (SAQ) Angina Frequency and Quality of Life domains, as well as the SAQ Summary Score. Among the study population, women were older, more often single, had lower levels of education, and had a higher prevalence of cardiac risk factors such as hypertension and diabetes mellitus. Women had lower mean 1-year SAQ Angina Frequency scores (mean±SD, 91.0±17.3 versus 93.9±13.3; P<0.01), SAQ Quality of Life scores (mean±SD, 67.3±23.0 versus 70.6±21.6; P<0.01), and SAQ Summary Scores (mean±SD, 81.6±13.8 versus 84.8±11.9; P<0.01), a difference of marginal clinical significance that persisted after multivariable adjustment. A slightly larger improvement in the SAQ Summary Score was observed in women as compared with men (20.9±22.6 versus 18.5±21.3; P=0.007) in unadjusted analysis. However, women were less likely to achieve clinically significant improvement in SAQ Angina Frequency (adjusted odds ratio, 0.67; 95% CI, 0.45-1.00) and SAQ Quality of Life (adjusted odds ratio, 0.73; 95% CI, 0.56-0.96) after adjustment. Conclusions There were no clinically significant differences in 1-year health status outcomes and improvement in health status by sex among patients without acute myocardial infarction following percutaneous coronary intervention. However, female sex was associated with poorer 1-year health status and a lower likelihood of experiencing clinically improvement in health status.
