Intravascular Imaging-Guided Optimization of Complex Percutaneous Coronary Intervention by Sex: A Subgroup Analysis of the RENOVATE-COMPLEX-PCI Trial. JAMA Cardiol 2024; 9:466-474. [PMID: 38568686 PMCID: PMC10993152 DOI: 10.1001/jamacardio.2024.0291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 02/02/2024] [Indexed: 04/06/2024]
Abstract
Importance There have been heterogeneous results related to sex differences in prognosis after percutaneous coronary artery intervention (PCI) for complex coronary artery lesions. Objective To evaluate potential differences in outcomes with intravascular imaging-guided PCI of complex coronary artery lesions between women and men. Design, Setting, and Participants This prespecified substudy evaluates the interaction of sex in the investigator-initiated, open-label, multicenter RENOVATE-COMPLEX-PCI randomized clinical trial, which demonstrated the superiority of intravascular imaging-guided PCI compared with angiography-guided PCI in patients with complex coronary artery lesions. The trial was conducted at 20 sites in Korea. Patients with complex coronary artery lesions undergoing PCI were enrolled between May 2018 and May 2021, and the median (IQR) follow-up period was 2.1 (1.4-3.0) years. Data were analyzed from December 2022 to December 2023. Interventions After diagnostic coronary angiography, eligible patients were randomly assigned in a 2:1 ratio to receive intravascular imaging-guided PCI or angiography-guided PCI. The choice and timing of the intravascular imaging device were left to the operators' discretion. Main Outcomes and Measures The primary end point was target vessel failure, defined as a composite of cardiac death, target vessel-related myocardial infarction, or clinically driven target vessel revascularization. Secondary end points included individual components of the primary end point. Results Of 1639 included patients, 339 (20.7%) were women, and the mean (SD) age was 65.6 (10.2) years. There was no difference in the risk of the primary end point between women and men (9.4% vs 8.3%; adjusted hazard ratio [HR], 1.39; 95% CI, 0.89-2.18; P = .15). Intravascular imaging-guided PCI tended to have lower incidence of the primary end point than angiography-guided PCI in both women (5.2% vs 14.5%; adjusted HR, 0.34; 95% CI, 0.15-0.78; P = .01) and men (8.3% vs 11.7%; adjusted HR, 0.72; 95% CI, 0.49-1.05; P = .09) without significant interaction (P for interaction = .86). Conclusions and Relevance In patients undergoing complex PCI, compared with angiographic guidance, intravascular imaging guidance was associated with similar reduction in the risk of target vessel failure among women and men. The treatment benefit of intravascular imaging-guided PCI showed no significant interaction between treatment strategy and sex. Trial Registration ClinicalTrials.gov Identifier: NCT03381872.

Sex differences in outcomes after acute coronary syndrome vary with age: a New Zealand national study. EUROPEAN HEART JOURNAL. ACUTE CARDIOVASCULAR CARE 2024; 13:284-292. [PMID: 38085048 PMCID: PMC10927026 DOI: 10.1093/ehjacc/zuad151] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 12/04/2023] [Accepted: 12/07/2023] [Indexed: 03/13/2024]
Abstract
AIMS This study investigated age-specific sex differences in short- and long-term clinical outcomes following hospitalization for a first-time acute coronary syndrome (ACS) in New Zealand (NZ). METHODS AND RESULTS Using linked national health datasets, people admitted to hospital for a first-time ACS between January 2010 and December 2016 were included. Analyses were stratified by sex and 10-year age groups. Logistic and Cox regression were used to assess in-hospital death and from discharge the primary outcome of time to first cardiovascular (CV) readmission or death and other secondary outcomes at 30 days and 2 years. Among 63 245 people (mean age 69 years, 40% women), women were older than men at the time of the ACS admission (mean age 73 vs. 66 years), with a higher comorbidity burden. Overall compared with men, women experienced higher rates of unadjusted in-hospital death (10% vs. 7%), 30-day (16% vs. 12%) and 2-year (44% vs. 34%) death, or CV readmission (all P < 0.001). Age group-specific analyses showed sex differences in outcomes varied with age, with younger women (<65 years) at higher risk than men and older women (≥85 years) at lower risk than men: unadjusted hazard ratio of 2-year death or CV readmission for women aged 18-44 years = 1.51 [95% confidence interval (CI) 1.21-1.84] and aged ≥85 years = 0.88 (95% CI 0.83-0.93). The increased risk for younger women was no longer significant after multivariable adjustment whereas the increased risk for older men remained. CONCLUSION Men and women admitted with first-time ACS have differing age and comorbidity profiles, resulting in contrasting age-specific sex differences in the risk of adverse outcomes between the youngest and oldest age groups.

Management of cardiac emergencies in women: a clinical consensus statement of the Association for Acute CardioVascular Care (ACVC), the European Association of Percutaneous Cardiovascular Interventions (EAPCI), the Heart Failure Association (HFA), and the European Heart Rhythm Association (EHRA) of the ESC, and the ESC Working Group on Cardiovascular Pharmacotherapy. EUROPEAN HEART JOURNAL OPEN 2024; 4:oeae011. [PMID: 38628674 PMCID: PMC11020263 DOI: 10.1093/ehjopen/oeae011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/10/2024] [Accepted: 02/22/2024] [Indexed: 04/19/2024]
Abstract
Cardiac emergencies in women, such as acute coronary syndromes, acute heart failure, and cardiac arrest, are associated with a high risk of adverse outcomes and mortality. Although women historically have been significantly underrepresented in clinical studies of these diseases, the guideline-recommended treatment for these emergencies is generally the same for both sexes. Still, women are less likely to receive evidence-based treatment compared to men. Furthermore, specific diseases affecting predominantly or exclusively women, such as spontaneous coronary dissection, myocardial infarction with non-obstructive coronary arteries, takotsubo cardiomyopathy, and peripartum cardiomyopathy, require specialized attention in terms of both diagnosis and management. In this clinical consensus statement, we summarize current knowledge on therapeutic management of these emergencies in women. Key statements and specific quality indicators are suggested to achieve equal and specific care for both sexes. Finally, we discuss several gaps in evidence and encourage further studies designed and powered with adequate attention for sex-specific analysis.

Factors Associated With Hospital Mortality in Acute Myocardial Infarction. KARDIOLOGIIA 2023; 63:29-35. [PMID: 38088110 DOI: 10.18087/cardio.2023.11.n2406] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Accepted: 02/10/2023] [Indexed: 12/18/2023]
Abstract
Aim To determine clinical and laboratory parameters associated with in-hospital mortality in patients with acute myocardial infarction and to develop a multifactorial prognostic model of in-hospital mortality.Material and methods This was a study based on the 2019-2020 Registry of acute coronary syndrome of the Tyumen Cardiology Research Center, a branch of the Tomsk National Research Medical Center. The study included 477 patients with ST-segment elevation acute myocardial infarction (AMI), 617 patients with non-ST segment elevation AMI, and 26 patients with unspecified AMI. In-hospital mortality was 6.0 % (n=67). Clinical and laboratory parameters were assessed on the day of admission. The separation power of indicators associated with in-hospital mortality was determined using a ROC analysis. The data array of each quantitative parameter was converted into a binary variable according to the obtained cut-off thresholds, followed by creation of a multifactorial model for predicting in-hospital mortality using a stepwise analysis with backward inclusion (Wald). The null hypothesis was rejected at p<0.05.Results The multivariate model for prediction of in-hospital mortality included age (cut-off, 72 years), OR 3.0 (95 % CI: 1.5-5.6); modified shock index (cut-off threshold, 0.87), OR 1.5 (95 % CI: 1.1-2.0); creatine phosphokinase-MB (cut-off threshold, 32.8 U / L), OR 4.1 (95 % CI: 2.2-7.7); hemoglobin (121.5 g / l), OR 1.7 (95 % CI: 1.2-2.3); leukocytes (11.5×109 / l), OR 1.9 (95 % CI: 1.3-2.6); glomerular filtration rate (60.9 ml / min), OR 1.7 (95 % CI: 1.2-2.2); left ventricular ejection fraction (42.5 %), OR 4.1 (95 % CI: 2.0-8.3); and size of myocardial asynergy (32.5 %), OR 2.6 (95 % CI: 1.4-5.0).Conclusions Independent predictors of in-hospital mortality in AMI are age, modified shock index, creatine phosphokinase-MB, peripheral blood leukocyte count, hemoglobin concentration, left ventricular ejection fraction, size of myocardial asynergy, and glomerular filtration rate. The in-hospital mortality model had a high predictive potential: AUC 0.930 (95 % CI: 0.905-0.954; p <0.001) with a cutoff threshold of 0.15; sensitivity 0.851, and specificity 0.850.

Impact of Sex- and Gender-Related Factors on Length of Stay Following Non-ST-Segment-Elevation Myocardial Infarction: A Multicountry Analysis. J Am Heart Assoc 2023; 12:e028553. [PMID: 37489737 PMCID: PMC10492965 DOI: 10.1161/jaha.122.028553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Accepted: 03/30/2023] [Indexed: 07/26/2023]
Abstract
Background Gender-related factors are psycho-socio-cultural characteristics and are associated with adverse clinical outcomes in acute myocardial infarction, independent of sex. Whether sex- and gender-related factors contribute to the substantial heterogeneity in hospital length of stay (LOS) among patients with non-ST-segment-elevation myocardial infarction remains unknown. Methods and Results This observational cohort study combined and analyzed data from the GENESIS-PRAXY (Gender and Sex Determinants of Cardiovascular Disease: From Bench to Beyond Premature Acute Coronary Syndrome study), EVA (Endocrine Vascular Disease Approach study), and VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI [Acute Myocardial Infarction] Patients study) cohorts of adults hospitalized across Canada, the United States, Switzerland, Italy, Spain, and Australia for non-ST-segment-elevation myocardial infarction. In total, 5219 participants were assessed for eligibility. Sixty-three patients were excluded for missing LOS, and 2938 were excluded because of no non-ST-segment-elevation myocardial infarction diagnosis. In total, 2218 participants were analyzed (66% women; mean±SD age, 48.5±7.9 years; 67.8% in the United States). Individuals with longer LOS (51%) were more likely to be White race, were more likely to have diabetes, hypertension, and a lower income, and were less likely to be employed and have completed secondary education. No univariate association between sex and LOS was observed. In the adjusted multivariable model, age (0.62 d/10 y; P<0.001), unemployment (0.63 days; P=0.01), and some of countries included relative to Canada (Italy, 4.1 days; Spain, 1.7 days; and the United States, -1.0 days; all P<0.001) were independently associated with longer LOS. Medical history mediated the effect of employment on LOS. No interaction between sex and employment was observed. Longer LOS was associated with increased 12-month all-cause mortality. Conclusions Older age, unemployment, and country of hospitalization were independent predictors of LOS, regardless of sex. Individuals employed with non-ST-segment-elevation myocardial infarction were more likely to experience shorter LOS. Sociocultural factors represent a potential target for improvement in health care expenditure and resource allocation.

Thirty-Day Unplanned Readmissions Following Elective and Acute Percutaneous Coronary Intervention. Heart Lung Circ 2023; 32:619-628. [PMID: 37003938 DOI: 10.1016/j.hlc.2023.02.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 12/04/2022] [Accepted: 02/28/2023] [Indexed: 04/03/2023]
Abstract
BACKGROUND Prior studies have reported a high rate of unplanned readmissions following acute percutaneous coronary intervention (PCI). Data outside the USA comparing 30-day unplanned readmissions following elective PCI to those who undergo acute PCI remain limited. METHODS Patients who underwent a PCI procedure in Australia and New Zealand between 2010 and 2015 were included. We determined the rates, causes and predictors of 30-day unplanned readmissions, as well as rates of repeat revascularisation procedures, for patients who underwent an elective or acute PCI. Predictors of readmissions were identified using logistic regression. RESULTS A total of 199,686 PCI encounters were included, of which 74,890 (37.5%) were elective and 124,796 (62.5%) were acute procedures. Overall, 10.6% of patients had at least one unplanned readmission within 30 days of discharge with lower rates following elective PCI (7.0%) compared to acute PCI (12.7%) (p<0.01). Non-specific chest pain was the commonest cause of readmission after elective and acute PCI, accounting for 20.7% and 21.5% of readmission diagnoses, respectively. Readmissions for acute myocardial infarction (13.0% vs 4.6%, p<0.01) and heart failure (6.5% vs 3.3%, p<0.01) were higher following acute PCI compared to elective PCI. Among readmitted patients, 16.7% had a coronary catheterisation, 12.2% had a PCI and 0.7% had coronary artery bypass surgery. Multivariable predictors of 30-day unplanned readmission included female sex and comorbidities such as heart failure, metastatic disease, chronic lung disease and renal failure (p<0.0001 for all). CONCLUSIONS Unplanned readmissions following elective or acute PCI are high. Clinical and quality-control measures are required to prevent avoidable readmissions in both settings.

Abstract
BACKGROUND There is a scarcity of studies comparing the clinical outcomes after percutaneous coronary intervention (PCI) for women and men stratified by the presentation of acute coronary syndromes (ACS) or stable coronary artery disease (CAD).Methods and Results: The study population included 26,316 patients who underwent PCI (ACS: n=11,119, stable CAD: n=15,197) from the CREDO-Kyoto PCI/CABG registry Cohort-2 and Cohort-3. The primary outcome was all-cause death. Among patients with ACS, women as compared with men were much older. Among patients with stable CAD, women were also older than men, but with smaller difference. The cumulative 5-year incidence of all-cause death was significantly higher in women than in men in the ACS group (26.2% and 17.9%, log rank P<0.001). In contrast, it was significantly lower in women than in men in the stable CAD group (14.2% and 15.8%, log rank P=0.005). After adjusting confounders, women as compared with men were associated with significantly lower long-term mortality risk with stable CAD but not with ACS (hazard ratio [HR]: 0.75, 95% confidence interval [CI]: 0.69-0.82, P<0.001, and HR: 0.92, 95% CI: 0.84-1.01, P=0.07, respectively). There was a significant interaction between the clinical presentation and the mortality risk of women relative to men (interaction P=0.002). CONCLUSIONS Compared with men, women had significantly lower adjusted mortality risk after PCI among patients with stable CAD, but not among those with ACS.

Mortality and Heart Failure Hospitalization Among Young Adults With and Without Cardiogenic Shock After Acute Myocardial Infarction. J Card Fail 2023; 29:18-29. [PMID: 36130688 PMCID: PMC10403806 DOI: 10.1016/j.cardfail.2022.08.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 08/15/2022] [Accepted: 08/22/2022] [Indexed: 01/17/2023]
Abstract
OBJECTIVES To investigate risk factors and outcomes of cardiogenic shock complicating acute myocardial infarction (AMI-CS) in young patients with AMI. BACKGROUND AMI-CS is associated with high morbidity and mortality rates. Data regarding AMI-CS in younger individuals are limited. METHODS AND RESULTS Consecutive patients with type 1 AMI aged 18-50 years admitted to 2 large tertiary-care academic centers were included, and they were adjudicated as having cardiogenic shock (CS) by physician review of electronic medical records using the Society for Cardiovascular Angiography and Interventions CS classification system. Outcomes included all-cause mortality (ACM), cardiovascular mortality (CVM) and 1-year hospitalization for heart failure (HHF). In addition to using the full population, matching was also used to define a comparator group in the non-CS cohort. Among 2097 patients (mean age 44 ± 5.1 years, 74% white, 19% female), AMI-CS was present in 148 (7%). Independent risk factors of AMI-CS included ST-segment elevation myocardial infarction, left main disease, out-of-hospital cardiac arrest, female sex, peripheral vascular disease, and diabetes. Over median follow-up of 11.2 years, young patients with AMI-CS had a significantly higher risk of ACM (adjusted HR 2.84, 95% CI 1.68-4.81; P < 0.001), CVM (adjusted HR 4.01, 95% CI 2.17-7.71; P < 0.001), and 1-year HHF (adjusted HR 5.99, 95% CI 2.04-17.61; P = 0.001) compared with matched non-AMI-CS patients. Over the course of the study, there was an increase in the incidence of AMI-CS among young patients with MI as well as rising mortality rates for patients with both AMI-CS and non-AMI-CS. CONCLUSIONS Of young patients with AMI, 7% developed AMI-CS, which was associated with a significantly elevated risk of mortality and HHF.

Sex-specific evaluation and redevelopment of the GRACE score in non-ST-segment elevation acute coronary syndromes in populations from the UK and Switzerland: a multinational analysis with external cohort validation. Lancet 2022; 400:744-756. [PMID: 36049493 DOI: 10.1016/s0140-6736(22)01483-0] [Citation(s) in RCA: 33] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 07/24/2022] [Accepted: 07/25/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND The Global Registry of Acute Coronary Events (GRACE) 2.0 score was developed and validated in predominantly male patient populations. We aimed to assess its sex-specific performance in non-ST-segment elevation acute coronary syndromes (NSTE-ACS) and to develop an improved score (GRACE 3.0) that accounts for sex differences in disease characteristics. METHODS We evaluated the GRACE 2.0 score in 420 781 consecutive patients with NSTE-ACS in contemporary nationwide cohorts from the UK and Switzerland. Machine learning models to predict in-hospital mortality were informed by the GRACE variables and developed in sex-disaggregated data from 386 591 patients from England, Wales, and Northern Ireland (split into a training cohort of 309 083 [80·0%] patients and a validation cohort of 77 508 [20·0%] patients). External validation of the GRACE 3.0 score was done in 20 727 patients from Switzerland. FINDINGS Between Jan 1, 2005, and Aug 27, 2020, 400 054 patients with NSTE-ACS in the UK and 20 727 patients with NSTE-ACS in Switzerland were included in the study. Discrimination of in-hospital death by the GRACE 2.0 score was good in male patients (area under the receiver operating characteristic curve [AUC] 0·86, 95% CI 0·86-0·86) and notably lower in female patients (0·82, 95% CI 0·81-0·82; p<0·0001). The GRACE 2.0 score underestimated in-hospital mortality risk in female patients, favouring their incorrect stratification to the low-to-intermediate risk group, for which the score does not indicate early invasive treatment. Accounting for sex differences, GRACE 3.0 showed superior discrimination and good calibration with an AUC of 0·91 (95% CI 0·89-0·92) in male patients and 0·87 (95% CI 0·84-0·89) in female patients in an external cohort validation. GRACE 3·0 led to a clinically relevant reclassification of female patients to the high-risk group. INTERPRETATION The GRACE 2.0 score has limited discriminatory performance and underestimates in-hospital mortality in female patients with NSTE-ACS. The GRACE 3.0 score performs better in men and women and reduces sex inequalities in risk stratification.

Abstract
Among patients presenting with acute myocardial infarction (AMI), the proportion of young individuals has increased in recent years. Although coronary atherosclerosis is less extensive in young patients with AMI, with higher prevalence of single-vessel disease and rare left main involvement, the long-term prognosis is not benign. Young patients with AMI with obstructive coronary artery disease have similar risk factors as older patients except for higher prevalence of smoking, lipid disorders, and family history of premature coronary artery disease, and lower prevalence of diabetes mellitus and hypertension. Smoking cessation is by far the most effective secondary preventive measure. Myocardial infarction with nonobstructive coronary arteries is a relatively common clinical entity (10%-20%) among young patients with AMI, with intravascular and cardiac magnetic resonance imaging being key for diagnosis and potentially treatment. Spontaneous coronary artery dissection is a frequent pathogenetic mechanism of AMI among young women, requiring a high degree of suspicion, especially in the peripartum period.

Abstract
BACKGROUND Sex differences in clinical characteristics and in-hospital outcomes among patients with non-ST-segment-elevation myocardial infarction have been described in Western countries, but whether these differences exist in China is unknown. METHODS We used a 2-stage random sampling design to create a nationally representative sample of patients admitted to 151 Chinese hospitals for non-ST-segment-elevation myocardial infarction in 2006, 2011, and 2015 and examined sex differences in clinical profiles, treatments, and in-hospital outcomes over this time. Multivariable logistic regression models adjusting for age or other potentially confounding clinical covariates were used to estimate these sex-specific differences. RESULTS Among 4611 patients, the proportion of women (39.8%) was unchanged between 2006 and 2015. Women were older with higher rates of hypertension, diabetes, and dyslipidemia. Among patients without contraindications, women were less likely to receive treatments than men, with significant differences for aspirin in 2015 (90.3% versus 93.9%) and for invasive strategy in 2011 (28.7% versus 45.7%) and 2015 (34.0% versus 48.4%). After adjusting for age, such differences in aspirin and invasive strategy in 2015 were not significant, but the difference in invasive strategy in 2011 persisted. The sex gaps in the use of invasive strategy did not narrow. From 2006 to 2015, a significant decrease in in-hospital mortality was observed in men (from 16.9% to 8.7%), but not in women (from 11.8% to 12.0%), with significant interaction between sex and study year (P=0.023). After adjustment, in-hospital mortality in women was significantly lower than men in 2006, but not in 2011 or 2015. CONCLUSIONS Sex differences in cardiovascular risk factors and invasive strategy after non-ST-segment-elevation myocardial infarction were observed between 2011 and 2015 in China. Although sex gaps in in-hospital mortality were largely explained by age differences, efforts to narrow sex-related disparities in quality of care should remain a focus. REGISTRATION URL: http://www.

Abstract
AIM The guideline for coronary artery revascularization replaces the 2011 coronary artery bypass graft surgery and the 2011 and 2015 percutaneous coronary intervention guidelines, providing a patient-centric approach to guide clinicians in the treatment of patients with significant coronary artery disease undergoing coronary revascularization as well as the supporting documentation to encourage their use. METHODS A comprehensive literature search was conducted from May 2019 to September 2019, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Collaboration, CINHL Complete, and other relevant databases. Additional relevant studies, published through May 2021, were also considered. Structure: Coronary artery disease remains a leading cause of morbidity and mortality globally. Coronary revascularization is an important therapeutic option when managing patients with coronary artery disease. The 2021 coronary artery revascularization guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to managing patients with coronary artery disease who are being considered for coronary revascularization, with the intent to improve quality of care and align with patients' interests.

Abstract
AIM The guideline for coronary artery revascularization replaces the 2011 coronary artery bypass graft surgery and the 2011 and 2015 percutaneous coronary intervention guidelines, providing a patient-centric approach to guide clinicians in the treatment of patients with significant coronary artery disease undergoing coronary revascularization as well as the supporting documentation to encourage their use. METHODS A comprehensive literature search was conducted from May 2019 to September 2019, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Collaboration, CINHL Complete, and other relevant databases. Additional relevant studies, published through May 2021, were also considered. STRUCTURE Coronary artery disease remains a leading cause of morbidity and mortality globally. Coronary revascularization is an important therapeutic option when managing patients with coronary artery disease. The 2021 coronary artery revascularization guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to managing patients with coronary artery disease who are being considered for coronary revascularization, with the intent to improve quality of care and align with patients' interests.

Prognosis Impact of Diabetes in Elderly Women and Men with Non-ST Elevation Acute Coronary Syndrome. J Clin Med 2021; 10:jcm10194403. [PMID: 34640420 PMCID: PMC8509190 DOI: 10.3390/jcm10194403] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 09/15/2021] [Accepted: 09/21/2021] [Indexed: 01/30/2023] Open
Abstract
Few studies have addressed to date the interaction between sex and diabetes mellitus (DM) in the prognosis of elderly patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). Our aim was to address the role of DM in the prognosis of non-selected elderly patients with NSTEACS according to sex. A retrospective analysis from 11 Spanish NSTEACS registries was conducted, including patients aged ≥70 years. The primary end point was one-year all-cause mortality. A total of 7211 patients were included, 2,770 (38.4%) were women, and 39.9% had DM. Compared with the men, the women were older (79.95 ± 5.75 vs. 78.45 ± 5.43 years, p < 0.001) and more often had a history of hypertension (77% vs. 83.1%, p < 0.01). Anemia and chronic kidney disease were both more common in women. On the other hand, they less frequently had a prior history of arteriosclerotic cardiovascular disease or comorbidities such as peripheral artery disease and chronic pulmonary disease. Women showed a worse clinical profile on admission, though an invasive approach and in-hospital revascularization were both more often performed in men (p < 0.001). At a one-year follow-up, 1090 patients (15%) had died, without a difference between sexes. Male sex was an independent predictor of mortality (HR = 1.15, 95% CI 1.01 to 1.32, p = 0.035), and there was a significant interaction between sex and DM (p = 0.002). DM was strongly associated with mortality in women (HR: 1.45, 95% CI = 1.18–1.78; p < 0.001), but not in men (HR: 0.98, 95% CI = 0.84–1.14; p = 0.787). In conclusion, DM is associated with mortality in older women with NSTEACS, but not in men.

Management of acute coronary syndromes in older adults. Eur Heart J 2021; 43:1542-1553. [PMID: 34347065 DOI: 10.1093/eurheartj/ehab391] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 04/03/2021] [Accepted: 06/03/2021] [Indexed: 12/22/2022] Open
Abstract
Older patients are underrepresented in prospective studies and randomized clinical trials of acute coronary syndromes (ACS). Over the last decade, a few specific trials have been conducted in this population, allowing more evidence-based management. Older adults are a heterogeneous, complex, and high-risk group whose management requires a multidimensional clinical approach beyond coronary anatomic variables. This review focuses on available data informing evidence-based interventional and pharmacological approaches for older adults with ACS, including guideline-directed management. Overall, an invasive approach appears to demonstrate a better benefit-risk ratio compared to a conservative one across the ACS spectrum, even considering patients' clinical complexity and multiple comorbidities. Conversely, more powerful strategies of antithrombotic therapy for secondary prevention have been associated with increased bleeding events and no benefit in terms of mortality reduction. An interdisciplinary evaluation with geriatric assessment should always be considered to achieve a holistic approach and optimize any treatment on the basis of the underlying biological vulnerability.

Patient Risk Interpretation of Symptoms Model (PRISM): How Patients Assess Cardiac Risk. J Gen Intern Med 2021; 36:2205-2211. [PMID: 34100233 PMCID: PMC8342696 DOI: 10.1007/s11606-021-06770-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Accepted: 03/29/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND While there is a prevailing perception that coronary artery disease (CAD) is a "man's disease," little is known about the factors which influence cardiac risk assessment and whether it varies by gender. OBJECTIVES 1) Qualitatively capture the complexity of cardiac risk assessment from a patient-centered perspective. 2) Explore how risk assessment may vary by gender. 3) Quantitatively validate qualitative findings among a new sample. DESIGN This study was conducted in two parts: (1) semi-structured in-depth interviews were audio-recorded, transcribed verbatim, and analyzed using modified grounded theory; (2) emergent themes were surveyed in a separate sample to validate findings quantitatively. Differences were estimated using 2-tailed t-tests and kappa. PARTICIPANTS Participants who were referred for their first elective coronary angiogram for suspected CAD with at least 1 prior abnormal test were recruited from a tertiary care hospital. MAIN MEASURES Patient-centered themes were derived from part one. In part two, patients estimated the probability that their symptoms were heart-related at multiple time points. RESULTS Part 1 included 14 men and 17 women (mean age=63.3±11.8 years). Part 2 included 237 patients, of which 109 (46%) were women (mean age=66.0±11.3 years). Part 1 revealed that patients' risk assessment evolves in three distinct phases, which were captured using an Ishikawa framework entitled "Patient Risk Interpretation of Symptoms Model" (PRISM). Part 2 validated PRISM findings; while patients were more likely to attribute their symptoms to CAD over time (phase 1 vs. 3: 21% vs. 73%, p<0.001), women were marginally less likely than men to perceive symptoms as heart-related by phase 3 (67% women vs. 78% men, p=0.054). CONCLUSIONS Patient assessment of CAD risk evolves, and women are more likely to underestimate their risk than men. PRISM may be used as a clinical aid to optimize patient-centered care. Future studies should validate PRISM in different clinical settings.

One-year mortality in NSTEMI patients is unaffected by timing of PCI within the first week of admission: Results of a real-world cohort analysis. Catheter Cardiovasc Interv 2021; 98:E661-E667. [PMID: 34263520 DOI: 10.1002/ccd.29873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 06/24/2021] [Accepted: 07/05/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVES We aimed to explore the impact of time to percutaneous coronary intervention (PCI) (T2P) on 1-year mortality in non-ST-elevation myocardial infarction (NSTEMI) patients. BACKGROUND The current guidelines recommend an early invasive strategy for NSTEMI patients. However, impact of an early invasive strategy on mortality is a matter of debate. For that reason, real world data are of great value to determine the optimal treatment window. METHODS This retrospective single center cohort study was performed in a high-volume PCI center in Amsterdam, The Netherlands. Intermediate- and high-risk NSTEMI patients undergoing PCI were included. The main discriminant was timing of PCI after admission (T2P), stratified according to different time windows (<24 h, 24-72 h, 72 h-7 days or >7 days). We analyzed 1-year mortality and the time distribution of overall survival. RESULTS In total, 848 patients treated between January 1, 2016 and January 1, 2018 were included in the analysis. T2P was <24 h in 145 patients, 24-72 h in 192 patients, 72 h-7 days in 275 patients, and >7 days in 236 patients. The mean GRACE-risk score was 127.1 (SD 28.7), 130.0 (33.1), 133.8 (32.1), and 148.7 (34.6) respectively, p = <0.001. After adjusting for confounders, 1-year mortality in patients with T2P <24 h did not significantly differ when compared with T2P 24-72 h (OR = 1.08; 95% CI = 0.33-3.51) and T2P 72 h-7 days (OR 1.72; 95% CI = 0.57-5.21) but was significantly higher in T2P >7 days (OR = 3.20; 95% CI = 1.06-9.68). CONCLUSIONS In an unselected cohort of patients with NSTEMI, treatment by PCI <24 h did not lead to improved survival as compared to aT2P <7 days strategy. Delay in PCI >7 days after admission resulted in worse outcome.

Abstract
BACKGROUND The purpose of this study is to investigate the impact of oxygen therapy on cardiovascular outcomes in relation to sex in patients with confirmed myocardial infarction (MI). METHODS The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction trial randomized 6,629 patients to oxygen at 6 L/min for 6-12 hours or ambient air. In the present subgroup analysis including 5,010 patients (1,388 women and 3,622 men) with confirmed MI, we report the effect of supplemental oxygen on the composite of all-cause death, rehospitalization with MI, or heart failure at long-term follow-up, stratified according to sex. RESULTS Event rate for the composite endpoint was 18.1% in women allocated to oxygen, compared to 21.4% in women allocated to ambient air (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.65-1.05). In men, the incidence was 13.6% in patients allocated to oxygen compared to 13.3% in patients allocated to ambient air (HR 1.03, 95% CI 0.86-1.23). No significant interaction in relation to sex was found (P= .16). Irrespective of allocated treatment, the composite endpoint occurred more often in women compared to men (19.7 vs 13.4%, HR 1.51; 95% CI, 1.30-1.75). After adjustment for age alone, there was no difference between the sexes (HR 1.06, 95% CI 0.91-1.24), which remained consistent after multivariate adjustment. CONCLUSION Oxygen therapy in normoxemic MI patients did not significantly affect all-cause mortality or rehospitalization for MI or heart failure in women or men. The observed worse outcome in women was explained by differences in baseline characteristics, especially age.

Female sex as an independent predictor of high bleeding risk among East Asian percutaneous coronary intervention patients: A sex difference analysis. J Cardiol 2021; 78:431-438.

Abstract
BACKGROUND Sex differences in the outcomes following percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) have been identified in Western countries. However, data on the long-term outcomes for bleeding events, particularly in East Asia where the aging population is growing rapidly and consists predominantly of women, remain scarce. METHODS We analyzed 2,494 ACS survivors from a multicenter PCI registry who underwent PCI between 2009 and 2012. The primary outcome was readmission for major bleeding at 2 years. Survival curves were generated with the cumulative incidence function. The adjusted hazard ratios were evaluated for the primary outcomes by sex using (1) Fine-Gray models and (2) Cox regression models. RESULTS There were 548 women (22.0%) in this cohort. The women were older (73.7 ± 10.8 years vs. 65.4 ± 11.8 years, p < 0.001), had a lower body mass index (23.0 ± 3.9 vs. 24.3 ± 3.6, p < 0.001), and had more comorbidities such as renal failure (49.4% vs. 36.3%, p < 0.001) and previous heart failure (8.4% vs. 4.5%, p < 0.001). Fewer women were discharged with statins (81.9% vs. 86.5%, p = 0.025) or beta blockers (70.6% vs. 77.1%, p = 0.007). During the 2-year follow-up, the unadjusted readmission rates for bleeding were higher among women (4.9% versus 2.4% at 2 years after discharge). Multivariable competing risk analysis with the Fine-Gray model and Cox regression model further demonstrated that female sex was associated with a higher risk of bleeding. CONCLUSIONS Among patients treated with PCI, women had a higher incidence of bleeding events requiring readmission. Sex disparities in the etiologies of readmission following PCI suggest the need for targeted treatment strategies. A strict follow-up after discharge could be beneficial for women to further reduce their risk.

Abstract
BACKGROUND Women with acute coronary syndrome (ACS) generally present with more comorbidities and experience worse clinical outcomes compared with males. However, it is unclear whether this represents genuine sex-related difference or stems from clinical, procedural and socioeconomic factors. METHODS We analyzed consecutive patients undergoing percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI), non-STEMI or unstable angina at a single tertiary-care center. Exclusion criteria were unknown sex, age < 18 years and PCI with bare metal stent or without stent placement. The study population was stratified according to sex. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE) defined as the composite of death, spontaneous myocardial infarction, or stroke at 1 year. Secondary endpoints were individual components of MACCE, target vessel revascularization (TVR) and clinically significant bleeding. RESULTS Of the 7362 patients included, 5031 (68.3%) were men and 2331 (31.7%) women. Women were older and presented with a higher burden of comorbidities while men had more complex coronary anatomy. The incidence of 1 year MACCE was significantly higher among women (8.0% versus 5.6%; p < 0.01) compared to men. Women also experienced a higher rate of bleeding (2.3% vs. 1.4%; p = 0.02) while there were no differences between groups in terms of TVR (8.1% vs. 7.8%; p-value = 0.83). Differences in outcomes were attenuated after multivariable adjustment. Findings were consistent across ACS subgroups. CONCLUSIONS In a contemporary ACS population treated with drug-eluting stents, women experienced a higher crude rate of 1-year MACCE. This was no longer apparent after accounting for baseline imbalances.

Abstract
Aims This study aims to evaluate the impact of the combination of cardiogenic shock (CS) and cardiac arrest (CA) complicating non‐ST‐segment elevation myocardial infarction (NSTEMI). Methods and results Adult (>18 years) NSTEMI admissions using the National Inpatient Sample database (2000 to 2017) were stratified by the presence of CA and/or CS. Outcomes of interest included in‐hospital mortality, early coronary angiography, hospitalization costs, and length of stay. Of the 7 302 447 hospitalizations due to NSTEMI, 147 795 (2.0%) had CS only, 155 522 (2.1%) had CA only, and 41 360 (0.6%) had both CS and CA. Compared with 2000, the adjusted odds ratios (ORs) and 95% confidence interval (CIs) for CS, CA, and both CS and CA in 2017 were 3.75 (3.58–3.92), 1.46 (1.42–1.50), and 4.52 (4.16–4.87), respectively (all P < 0.001). The CS + CA (61.2%) cohort had higher multiorgan failure than CS (42.3%) and CA only (32.0%) cohorts, P < 0.001. The CA only cohort had lower rates of overall (52% vs. 59–60%) and early (17% vs. 18–27%) angiography compared with the other groups (all P < 0.001). CS + CA admissions had higher in‐hospital mortality compared with those with CS alone (aOR 4.12 [95% CI 4.00–4.24]), CA alone (aOR 1.69 [95% CI 1.65–1.74]), or without CS/CA (aOR 22.66 [95% CI 22.06–23.27]). The presence of CS, either alone or with CA, was associated with higher hospitalization costs and longer hospital length of stay. Conclusions The combination of CS and CA is associated with higher rates of acute non‐cardiac organ failure and in‐hospital mortality in NSTEMI admissions as compared with those with either CS or CA alone.

Abstract
BACKGROUND Women are underrepresented across cardiovascular clinical trials. Whether women are more likely than men to prematurely discontinue study drug or withdraw consent once enrolled in a clinical trial is unknown. METHODS Eleven phase 3/4 TIMI (Thrombolysis in Myocardial Infarction) trials were included (135 879 men and 51 812 women [28%]). The association between sex and premature study drug discontinuation and withdrawal of consent were examined by multivariable logistic regression after adjusting for potential confounders in each individual trial and combining the individual point estimates in random effects models. RESULTS After adjusting for baseline differences, women had 22% higher odds of premature drug discontinuation (adjusted odds ratio [ORadj], 1.22 [95% CI, 1.16-1.28]; P<0.001) compared with men. Qualitatively consistent results were observed for women versus men in the placebo arms (ORadj, 1.20 [95% CI, 1.13-1.27]) and active therapy arms (ORadj, 1.23 [95% CI, 1.17-1.30)]; there was some evidence for regional heterogeneity (P interaction <0.001). Of those who stopped study drug prematurely, a similar proportion of men and women in the active arm stopped because of an adverse event (36% for both; P=0.60). Women were also more likely to withdraw consent compared with men (ORadj, 1.26 [95% CI, 1.17-1.36]; P<0.001). CONCLUSIONS Women were more likely than men to prematurely discontinue study drug and withdraw consent across cardiovascular outcome trials. Premature study drug discontinuation was not explained by baseline differences by sex or a higher proportion of adverse events. Future trials should better capture reasons for drug discontinuation and withdrawal of consent to understand barriers to continued study drug use and clinical trial participation, particularly among women.

Abstract
OBJECTIVE To assess the impact of female sex on the incidence, management, and outcomes of myocardial infarction (MI) in different age groups. METHODS Patients admitted with ST-elevation MI (STEMI) and non-ST-elevation MI (NSTEMI), between January 1, 2003, and December 31, 2015, were identified in the National Inpatient Sample. We compared STEMI and NSTEMI rates, management patterns, and in-hospital morbidity and mortality in men and women stratified into 4 age groups (<45, 45 to 64, 65 to 84, and ≥85 years of age). RESULTS A total of 6,720,639 weighted hospitalizations for MI (79.8% NSTEMI, and 20.2% STEMI) were included. The incidence rate of hospitalizations for MI was lower in women than men across all age groups. Women were less likely than men to undergo coronary angiography, revascularization, or to use circulatory-support devices. These differences were consistent across all age groups. Adjusted odds of death for women (vs men) varied by age: odds ratio (95% confidence interval) 1.08 (0.97 to 1.20), 1.05 (1.02 to 1.08), 0.92 (0.91 to 0.94), and 0.86 (0.85 to 0.88) for NSTEMI, and 1.15 (1.04 to 1.27), 1.22 (1.18 to 1.26), 1.09 (1.06 to 1.11), and 0.97 (0.94 to 0.99), for STEMI, in age groups (<45, 45 to 64, 65 to 84, and ≥85), respectively. The magnitude of differences in complications between men and women was higher in younger and middle-age patients. CONCLUSION Compared with men, women have lower incidence of MI and less likelihood of undergoing invasive treatment regardless of age. However, post-MI outcomes are age specific. The negative impact of female sex on most outcomes was most pronounced in young and middle-aged women.

Abstract
OBJECTIVE The platelet phenotype in certain patients and clinical contexts may differ from healthy conditions. We evaluated platelet activation through specific receptors in healthy men and women, comparing this to patients presenting with ST-segment-elevation myocardial infarction and non-ST-segment-elevation myocardial infarction. Approach and Results: We identified independent predictors of platelet activation through certain receptors and a murine MI model further explored these findings. Platelets from healthy women and female mice are more reactive through PARs (protease-activated receptors) compared with platelets from men and male mice. Multivariate regression analyses revealed male sex and non-ST-segment-elevation myocardial infarction as independent predictors of enhanced PAR1 activation in human platelets. Platelet PAR1 signaling decreased in women and increased in men during MI which was the opposite of what was observed during healthy conditions. Similarly, in mice, thrombin-mediated platelet activation was greater in healthy females compared with males, and lesser in females compared with males at the time of MI. CONCLUSIONS Sex-specific signaling in platelets seems to be a cross-species phenomenon. The divergent platelet phenotype in males and females at the time of MI suggests a sex-specific antiplatelet drug regimen should be prospectively evaluated.

Abstract
BACKGROUND Risk factors for further bleeding and ischemic events after acute coronary syndrome (ACS) often overlap. Little is known about sex-based differences in the management and outcomes of ACS patients according to their combined bleeding-ischemic risk. METHODS All ACS hospitalizations in the United Kingdom (2010-2017) were retrospectively analyzed, stratified by sex and bleeding-ischemic risk combination (using CRUSADE and GRACE scores). Multivariable logistic regression was performed to examine association between risk-groups and 1) receipt of guideline-recommended management and 2) in-hospital outcomes. RESULTS Of 584,360 patients, a third of males (32.3%) and females (32.6%) were in the dual high-risk group (High CRUSADE- High GRACE). In comparison to the dual low-risk group (Low CRUSADE-Low GRACE), the dual high-risk patients of both sexes were 59-83% less likely to receive inpatient revascularisation (PCI or CABG) and 50% less likely to receive dual antiplatelet therapy (DAPT) on discharge, with a significant increase in odds of MACE (~8 to 9-fold), all-cause and cardiac mortality (25 to 35-fold), and bleeding (78-91%). The greatest difference in management and clinical outcomes between sexes was found in the dual-high risk group where females were less likely to receive guideline-recommended therapy (revascularisation and DAPT), compared to males, and were more likely to experience MACE, all-cause and cardiac mortality. CONCLUSION ACS patients with dual high-risk for bleeding and recurrent ischemia, especially females, are less likely to receive guideline-recommended therapy and experience significantly worse outcomes. Novel strategies are needed to effectively manage this highly prevalent, complex patient group and address the under-treatment of females.

Variation in treatment strategy for non-ST segment elevation myocardial infarction: A multilevel methodological approach. Int J Cardiol 2020; 328:35-39. [PMID: 33278418 DOI: 10.1016/j.ijcard.2020.11.059] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 09/17/2020] [Accepted: 11/27/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Variations by hospital and region in the selection of an early invasive strategy (EIS) after non-ST-segment elevation myocardial infarction (NSTEMI) in patients with high-risk criteria are unknown. METHODS We evaluated the data of 7037 patients with NSTEMI from 20 hospitals of 3 regions from the Korean Acute Myocardial Infarction Registry-National Institute of Health database. We used hierarchical generalized linear mixed-models to estimate region- and hospital-level variation in the selection of an EIS after adjusting for patient-level high-risk criteria. We explored the variation using the median rate ratio (MRR), which estimates the relative difference in the risk ratios of two hypothetically identical patients at two different sites. RESULTS An EIS was selected in 84.4% of patients. At the hospital level, the median selection rate was 80.4%. At the region level, the median selection rate was 74.9% in the east region, 81.3% in the north region, and 83.9% in the west region, respectively. After adjusting for patient-level covariates, we found significant hospital- (MRR 2.19, 95% confidence interval [CI]: 1.74-3.03) and region-level (MRR 1.88, 95%CI: 1.26-5.44) variation in the selection of an EIS. Among patient-level factors, male sex, ongoing chest pain, history of coronary artery disease or acute heart failure, and GRACE risk score > 140 were independently associated with the selection of an EIS. CONCLUSIONS We observed significant hospital- and region-level variation in the selection of an EIS after NSTEMI in high-risk patients. Quality improvement efforts are required to standardize decision making and to improve clinical outcomes.

Comparison of Outcomes of Coronary Revascularization for Acute Myocardial Infarction in Men Versus Women. Am J Cardiol 2020; 132:1-7. [PMID: 32773227 DOI: 10.1016/j.amjcard.2020.07.014] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 07/02/2020] [Accepted: 07/03/2020] [Indexed: 11/25/2022]
Abstract
This study sought to examine the differences in the characteristics and outcomes between men and women who underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for acute myocardial infarction (AMI) in contemporary US practice. The Nationwide Inpatient Sample was used to identify patients who underwent revascularization for AMI between January 1, 2003 and December 31, 2016. The primary outcome was in-hospital mortality. Propensity score matching was utilized to account for differences in baseline characteristics. In total, 3,603,142 patients were included, of whom only 1,180,436 (33%) were women. Compared with men, women were older and had higher prevalence of key co-morbidities including diabetes, hypertension, congestive heart failure, and chronic kidney and lung disease (p <0.001). In the PCI cohort, women were significantly less likely to undergo multivessel PCI, to receive mechanical circulatory support, or to undergo atherectomy. In the CABG group, women were more likely to have concomitant valve surgery. In the propensity-matched cohorts, in-hospital mortality was higher for women than men regardless of revascularization strategy: 7.6% versus 6.6% for PCI in ST-elevation myocardial infarction, 2.0% versus 1.9% for PCI in non-ST-elevation myocardial infarction, and 5.7% versus 4.3% for CABG in any AMI (p <0.001). Women also had higher rates of major complications, longer hospitalizations, higher costs, and were less likely to be discharged home (vs nursing facility). These sex-based differences persisted over the study 14-year period. In conclusion, in a contemporary nationwide analysis of propensity score-matched patients, women who undergo revascularization for AMI have worse in-hospital outcomes than men regardless of revascularization mode.

Sex-related impacts on clinical outcomes after percutaneous coronary intervention. Sci Rep 2020; 10:15262. [PMID: 32943716 PMCID: PMC7498594 DOI: 10.1038/s41598-020-72296-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Accepted: 08/28/2020] [Indexed: 11/16/2022] Open
Abstract
The aim of this study is to investigate sex-related impacts on clinical outcomes after percutaneous coronary intervention (PCI). We analyzed 90,305 patients (29.0% of women) with the first episode of coronary artery disease who underwent PCI from the Korean National Health Insurance claims database between July 2013 and June 2017. Women were significantly older than men (71.5 ± 10.5 vs. 61.8 ± 11.7 years, p < 0.001). The study population had a median follow-up of 2.2 years (interquartile range, 1.2–3.3). In the propensity-score matched angina population (15,104 pairs), the in-hospital mortality of women was not different from men (odds ratio, 0.87; 95% confidence interval: 0.71–1.08, p = 0.202). However, the post-discharge mortality of women was significantly lower (hazard ratio, 0.74; 95% confidence interval: 0.69–0.80, p < 0.001) than that of men. In the propensity-score matched acute myocardial infarction (AMI) population (8,775 pairs), the in-hospital mortality of women was significantly higher than that of men (odds ratio, 1.19; 95% confidence interval: 1.05–1.34, p = 0.006). Meanwhile, there was no difference in mortality after discharge (hazard ratio, 0.98; 95% confidence interval: 0.91–1.06, p = 0.605). The post-discharge mortality of women was not higher than men under the contemporary PCI treatment. Altered sex-related impacts on clinical outcomes might be attributed to improved medical and procedural strategies.

Sex Disparities in Myocardial Infarction: Biology or Bias? Heart Lung Circ 2020; 30:18-26. [PMID: 32861583 DOI: 10.1016/j.hlc.2020.06.025] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 05/19/2020] [Accepted: 06/28/2020] [Indexed: 12/31/2022]
Abstract
Women have generally worse outcomes after myocardial infarction (MI) compared to men. The reasons for these disparities are multifactorial. At the beginning is the notion-widespread in the community and health care providers-that women are at low risk for MI. This can impact on primary prevention of cardiovascular disease in women, with lower use of preventative therapies and lifestyle counselling. It can also lead to delays in presentation in the event of an acute MI, both at the patient and health care provider level. This is of particular concern in the case of ST elevation MI (STEMI), where "time is muscle". Even after first medical contact, women with acute MI experience delays to diagnosis with less timely reperfusion and percutaneous coronary intervention (PCI). Compared to men, women are less likely to undergo invasive diagnostic testing or PCI. After being diagnosed with a STEMI, women receive less guideline-directed medical therapy and potent antiplatelets than men. The consequences of these discrepancies are significant-with higher mortality, major cardiovascular events and bleeding after MI in women compared to men. We review the sex disparities in pathophysiology, risk factors, presentation, diagnosis, treatment, and outcomes for acute MI, to answer the question: are they due to biology or bias, or both?

Sex Differences in the Outcomes of Elderly Patients with Acute Coronary Syndrome. Cardiol Res Pract 2020; 2020:5091490. [PMID: 32454999 PMCID: PMC7240792 DOI: 10.1155/2020/5091490] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Revised: 03/25/2020] [Accepted: 04/06/2020] [Indexed: 01/08/2023] Open
Abstract
Background The impact of sex on the outcome of patients with acute coronary syndrome (ACS) has been suggested, but little is known about its impact on elderly patients with ACS. Methods This study analyzed the impact of sex on in-hospital and 1-year outcomes of elderly (≥75 years of age) patients with ACS hospitalized in our department between January 2013 and December 2017. Results A total of 711 patients were included: 273 (38.4%) women and 438 (61.6%) men. Their age ranged from 75 to 94 years, similar between women and men. Women had more comorbidities (hypertension (79.5% vs. 72.8%, p=0.050), diabetes mellitus (35.2% vs. 26.5%, p=0.014), and hyperuricemia (39.9% vs. 32.4%, p=0.042)) and had a higher prevalence of non-ST-segment elevation ACS (NSTE-ACS) (79.5% vs. 71.2%, p=0.014) than men. The prevalence of current smoking (56.5% vs. 5.4%, p < 0.001), creatinine levels (124.4 ± 98.6 vs. 89.9 ± 54.1, p < 0.001), and revascularization rate (39.7% vs. 30.0%, p=0.022) were higher, and troponin TnT and NT-proBNP tended to be higher in men than in women. The in-hospital mortality rate was similar (3.5% vs. 4.4%, p=0.693), but the 1-year mortality rate was lower in women than in men (14.7% vs. 21.7%, p=0.020). The multivariable analysis showed that female sex was a protective factor for 1-year mortality in all patients (OR = 0.565, 95% CI 0.351–0.908, p=0.018) and in patients with STEMI (OR = 0.416, 95% CI 0.184–0.940, p=0.035) after adjustment. Conclusions Among the elderly patients with ACS, the 1-year mortality rate was lower in women than in men, which could be associated with comorbidities and ACS type.

Abstract
Background No studies from the Arabian Gulf region have taken age into account when examining sex differences in ST-segment-elevation myocardial infarction (STEMI) presentation and outcomes. We examined the relationship between sex differences and presenting characteristics, revascularization procedures, and in-hospital mortality after accounting for age in patients hospitalized with STEMI in the Arabian Gulf region from 2005 to 2017. Methods and Results This study was a pooled analysis of 31 620 patients with a diagnosis of acute coronary syndrome enrolled in 7 Arabian Gulf registries. Of these, 15 532 patients aged ≥18 years were hospitalized with a primary diagnosis of STEMI. A multiple variable regression model was used to assess sex differences in revascularization, in-hospital mortality, and 1-year mortality. Odds ratios and 95% CIs were calculated. Women were, on average, 8.5 years older than men (mean age: 61.7 versus 53.2 years; absolute standard mean difference: 68.9%). The age-stratified analysis showed that younger women (aged <65 years) with STEMI were more likely to seek acute medical care and were less likely to receive thrombolytic therapies or primary percutaneous coronary intervention and guideline-recommended pharmacotherapy than men. Women had higher crude in-hospital mortality than men, driven mainly by younger age (46-55 years, odds ratio: 2.60 [95% CI, 1.80-3.7]; P<0.001; 56-65 years, odds ratio: 2.32 [95% CI, 1.75-3.08]; P<0.001; and 66-75 years, odds ratio: 1.79 [95% CI, 1.33-2.41]; P<0.001). Younger women had higher adjusted in-hospital and 1-year mortality rates than younger men (P<0.001). Conclusions Younger women (aged ≤65 years) with STEMI were less likely to receive guideline-recommended pharmacotherapy and revascularization than younger men during hospitalization and had higher in-hospital and 1-year mortality rates.

Abstract
Background This study aims to investigate the gender differences in treatment strategies among non-ST-segment elevation myocardial infarction (NSTEMI) patients ≥80 years old in China. Methods A total of 190 consecutive NSTEMI patients ≥80 years old in Fuwai Hospital were included from 2014 to 2017. These patients were grouped by gender, and sub-grouped by conservative treatment or invasive treatment. The clinical characteristics, medical history, discharge drug used, and prognosis were collected and compared between these two treatment strategies. Results There were significant differences between these two treatment strategies in terms of GRACE grade, history of myocardial infarction (MI), after coronary artery bypass grafting (CABG), III grade, renal dysfunction, anemia, and use of diuretic (P<0.05). In addition, the age, creatinine and Killip class of female patients, and the death and good prognosis of male patients were found to be significantly different between these two treatment strategies (P<0.05). The multivariate logistic regression analysis revealed that the death of males was significantly associated with treatment strategies in the multivariable logistic regression analysis (P<0.05). In addition, the Kaplan-Meier survival analyses revealed that the survival rates of invasive strategy were significantly higher, when compared to that of conservative strategy in males (P=0.001) and females (P=0.015). Conclusions There were gender differences in treatment strategies among NSTEMI patients ≥80 years old. The difference in treatment strategies in males was more pronounced than in females, in terms of long-term survival rate.

Abstract
OBJECTIVE Current guidelines recommend a risk-adjusted early invasive strategy (EIS) in patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). The present study assesses the application if this strategy, the conditioning factors and prognostic impact upon patients with NSTEACS admitted to Intensive Cardiac Care Units (ICCU). DESIGN A prospective cohort study was carried out. SETTING The ICCUs of 8 hospitals in Catalonia (Spain). PATIENTS Consecutive patients with NSTEACS between October 2017 and March 2018. The risk profile was defined by the European Society of Cardiology criteria. INTERVENTIONS EIS was defined as the performance of coronary angiography within the first 6hours in patients at very high-risk or within 24hours in high-risk patients. OUTCOME VARIABLES Mortality or readmission at 6 months. RESULTS A total of 629 patients were included (mean age 66.6 years), of whom 225 (35.9%) were at very high risk, and 392 (62.6%) at high risk. Most patients (96.2%) underwent an invasive strategy. EIS was performed in 284 patients (45.6%), especially younger patients with fewer comorbidities. These patients had a shorter ICCU and hospital stay, as well as a lesser incidence of ACS, revascularization and death or readmission at 6 months. After adjusting for confounders, the association between EIS and death or readmission at 6 months remained significant (hazard ratio: .66, 95% confidence interval .45-.97; P=.035). CONCLUSIONS The EIS was performed in a minority of NSTEACS admitted to ICCU, being associated with better outcomes.

Abstract
OBJECTIVES The number of elderly patients undergoing coronary revascularization is steadily increasing, and data on the impact of gender on outcomes are scarce. This study sought to assess gender-related differences in outcomes in elderly patients with acute coronary syndromes (ACS). METHODS We investigated outcomes in elderly ACS patients referred for coronary angiography and prospectively enrolled in the Swiss ACS Cohort between December 2009 and October 2012. Adjudicated major adverse cardiovascular and cerebrovascular events (MACCE) included all-cause death, non-fatal myocardial infarction, clinically indicated repeat coronary revascularization, definite stent thrombosis, and transient ischemic attack/stroke. RESULTS Among 2,168 patients recruited, 481 (22%) patients were >75 years of age (37% women). In patients >75 years, 1-year MACCE rates were 15% and 23% in women and men (OR 0.59, 95% CI 0.36-0.97, P = 0.04), respectively, and differences remained significant after adjustments for baseline variables (adjusted OR 0.48, 95% CI 0.26-0.90, P = 0.02). Women >75 years had a lower cardiovascular mortality (6% versus 12%, adjusted OR 0.31, 95% CI 0.12-0.81, P = 0.02). In patients ≤75 years, 1-year MACCE rates did not differ between gender (10% and 8% for women and men, adjusted OR 1.28, 95% CI 0.77-2.14, P = 0.34). Rates of TIMI major bleeding for women and men were 4% and 4% in patients >75 years (P = 0.96), and 5% and 3% in those ≤75 years (P = 0.11). CONCLUSIONS The low rates of MACCE observed in elderly women in this patient cohort suggest that with current interventional strategies the gender gap in ACS management has been attenuated.
