Impact of Diabetes Mellitus on Ischemic Events in Men and Women After Percutaneous Coronary Intervention

Efficacy and Safety of Thirty-Day Dual-Antiplatelet Therapy Following Complex Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis

The optimal duration of DAPT after complex PCI remains under investigation. The purpose of this systematic review and meta-analysis was to explore the safety and efficacy of a one-month therapy period versus a longer duration of DAPT after complex PCI. We systematically screened three major databases, searching for randomized controlled trials or sub-analyses of them, which compared shortened DAPT (S-DAPT), namely, one month, and longer DAPT (L-DAPT), namely, more than three months. The primary endpoint was any Net Adverse Clinical Event (NACE), and the secondary was any MACE (Major Adverse Cardiac Event), its components (mortality, myocardial infarction, stroke, and stent thrombosis), and major bleeding events. Three studies were included in the analysis, with a total of 6275 patients. Shortening DAPT to 30 days after complex PCI did not increase the risk of NACEs (OR: 0.77, 95% CI: 0.52-1.14), MACEs, mortality, myocardial infractions, stroke, or stent thrombosis. Pooled major bleeding incidence was reduced, but this finding was not statistically significant. This systematic review and meta-analysis showed that one-month DAPT did not differ compared to a longer duration of DAPT after complex PCI in terms of safety and efficacy endpoints. Further studies are still required to confirm these findings.

Impact of chronic kidney disease and diabetes on clinical outcomes in women undergoing PCI

BACKGROUND

For women undergoing drug-eluting stent (DES) implantation, the individual and combined impact of chronic kidney disease (CKD) and diabetes mellitus (DM) on outcomes is uncertain.

AIMS

We sought to assess the impact of CKD and DM on prognosis in women after DES implantation.

METHODS

We pooled patient-level data on women from 26 randomised controlled trials comparing stent types. Women receiving DES were stratified into 4 groups based on CKD (defined as creatine clearance <60 mL/min) and DM status. The primary outcome at 3 years after percutaneous coronary intervention was the composite of all-cause death or myocardial infarction (MI); secondary outcomes included cardiac death, stent thrombosis and target lesion revascularisation.

RESULTS

Among 4,269 women, 1,822 (42.7%) had no CKD/DM, 978 (22.9%) had CKD alone, 981 (23.0%) had DM alone, and 488 (11.4%) had both conditions. The risk of all-cause death or MI was not increased in women with CKD alone (adjusted hazard ratio [adj. HR] 1.19, 95% confidence interval [CI]: 0.88-1.61) nor DM alone (adj. HR 1.27, 95% CI: 0.94-1.70), but was significantly higher in women with both conditions (adj. HR 2.64, 95% CI: 1.95-3.56; interaction p-value <0.001). CKD and DM in combination were associated with an increased risk of all secondary outcomes, whereas alone, each condition was only associated with all-cause death and cardiac death.

CONCLUSIONS

Among women receiving DES, the combined presence of CKD and DM was associated with a higher risk of the composite of death or MI and of any secondary outcome, whereas alone, each condition was associated with an increase in all-cause and cardiac death.

Feminism, gender medicine and beyond: a feminist analysis of "gender medicine"

The feminist women's health movement empowered women's knowledge regarding their health and battled against paternalistic and oppressive practices within healthcare systems. Gender Medicine (GM) is a new discipline that studies the effect of sex/gender on general health. The international society for gender medicine (IGM) was embraced by the FDA and granted funds by the European Union to formulate policies for medical practice and research.We conducted a review of IGM publications and policy statements in scientific journals and popular media. We found that while biological differences between men and women are emphasized, the impact of society on women is under- represented. The effect of gender-related violence, race, ethnic conflicts, poverty, immigration and discrimination on women's health is seldom recognized. Contrary to feminist practice, GM is practiced by physicians and scientists, neglecting voices of other disciplines and of women themselves.In this article we show that while GM may promote some aspects of women's health, at the same time it reaffirms conservative positions on sex and gender that can serve to justify discrimination and disregard the impact of society on women's lives and health. An alternative approach, that integrates feminist thinking and practices into medical science, practice and policies is likely to result in a deep and beneficiary change in women's health worldwide.

Sex differences in 1-year clinical outcomes after percutaneous coronary intervention with COMBO stents: From the COMBO collaboration

BACKGROUND

The COMBO drug eluting stent is a novel device with luminal endothelial progenitor cell capture technology for rapid homogeneous endothelialization.

METHODS AND RESULTS

We examined for sex differences in 1-year outcomes after COMBO stenting from the COMBO collaboration, a pooled patient-level dataset from the MASCOT and REMEDEE multicenter registries. The primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, target vessel-myocardial infarction (TV-MI), or clinically driven target lesion revascularization (CD-TLR). Secondary outcomes included stent thrombosis (ST). Adjusted outcomes were assessed using Cox regression methods. The study included 861 (23.8%) women and 2,753 (76.2%) men. Women were older with higher prevalence of several comorbidities including diabetes mellitus. Risk of 1-year TLF was similar in both sexes (3.8% vs. 3.9%, HR 0.92, 95% CI 0.59-1.42, p = .70), without sex differences in the incidence of cardiac death (1.6% vs. 1.5%, p = .78), TV-MI (1.5% vs. 1.1%, p = .32), or CD-TLR (2.0% vs. 2.2%, p = .67). Definite or probable ST occurred in 0.4% women and 1.0% men (HR 0.26, 95% CI 0.06-1.11, p = .069).

CONCLUSIONS

Despite greater clinical risks at baseline, women treated with COMBO stents had similarly low 1-year TLF and other ischemic outcomes compared to men.

Acute myocardial infarction in the young with diabetes mellitus- national inpatient sample study with sex-based difference in outcomes

BACKGROUND

Mortality after AMI is on the decreasing trend; however, this favorable trend is not observed in the young, especially women. Therefore, we conducted a retrospective analysis using the Nationwide Inpatient Sample (NIS) to identify sex-based outcomes following AMI in young with diabetes.

METHODS

NIS 2010-2014 was used to identify all patients with AMI using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Men (N = 30,950) and women (N = 17,928) patients diagnosed with diabetes were identified and stratified as young if age >18 and <45 years.

RESULTS

Young women with AMI and concomitant diabetes having a higher burden of overall traditional and non-traditional comorbidities. NSTEMI was the major presentation in women as compared to men. Young women with AMI and concomitant diabetes were less likely to receive revascularization with PCI [51.1% vs. 58.2%; OR 0.86, CI 0.78-0.94] or CABG [7.9% vs. 10.1%; OR 0.64, CI 0.54-0.75]. Adjusted all-cause in-hospital mortality did not differ significantly between the two groups [OR 1.06, CI 0.74-1.52]. Women had lower odds of developing cardiogenic shock, ventricular arrhythmias, and AKI, and were more likely to develop major bleeding requiring transfusion, and mitral regurgitation.

CONCLUSION

There were significant differences between young men and women with diabetes in terms of baseline characteristics and clinical presentation, use of revascularization, and cardiac complications, yet overall, in-hospital mortality does not appear to differ. More studies are needed to identify the interaction of sex and diabetes in young AMI population, and areas for practice improvement.

Impact of Diabetes Mellitus in Women Undergoing Percutaneous Coronary Intervention With Drug-Eluting Stents

BACKGROUND

Data examining the impact of diabetes mellitus (DM) on ischemic risk after percutaneous coronary intervention in women are limited as most clinical trial participants are male. We evaluated (1) the impact of DM on ischemic outcomes in women undergoing drug-eluting stent (DES) implantation and (2) whether the outcomes of new- versus early-generation DES vary by DM status.

METHODS AND RESULTS

We pooled patient-level data of 10 448 women undergoing percutaneous coronary intervention with DES from 26 randomized trials. Baseline characteristics and 3-year clinical outcomes were stratified according to DM status (noninsulin-dependent and insulin-dependent) and DES generation. The primary end point was the composite of all-cause death or myocardial infarction. Secondary end points were definite or probable stent thrombosis and target lesion revascularization. Compared with women without DM (n=7154, 68.5%), adjusted risks (adjusted hazard ratios [95% CI]) for death or myocardial infarction among women with noninsulin-dependent DM (n=2241, 21.4%) and insulin-dependent DM (n=1053, 10.1%) were 1.30 (1.11-1.53) and 1.71 (1.41-2.07), respectively ( P_trend<0.001). Similar trends were observed for def/prob stent thrombosis and target lesion revascularization. Compared with early-generation DES, use of newer-generation DES was associated with significant reductions in death or myocardial infarction in the absence of DM whereas differences were nonsignificant in the presence of DM, with similar findings for def/prob stent thrombosis and target lesion revascularization.

CONCLUSIONS

The presence of DM is associated with substantial, graded, and durable risks for ischemic events among women undergoing percutaneous coronary intervention with DES. The safety and efficacy profile of newer-generation DES is preserved among women without DM, while benefits are nonsignificant among women with DM.

Acute myocardial infarction in young women: current perspectives

Acute myocardial infarction (AMI) is the leading cause of death in women worldwide. Every year, in the USA alone, more than 30,000 young women <55 years of age are hospitalized with AMI. In recent decades, the incidence of AMI is increasing in younger women in the context of increasing metabolic syndrome, diabetes mellitus, and non-traditional risk factors such as stress, anxiety, and depression. Although women are classically considered to present with atypical chest pain, several observational data confirm that men and women experience similar rates of chest pain, with some differences in intensity, duration, radiation, and the choice of descriptors. Women also experience more number of symptoms and more prodromal symptoms compared with men. Suboptimal awareness, sociocultural and financial reasons result in pre-hospital delays in women and lower rates of access to care with resulting undertreatment with guideline-directed therapies. Causes of AMI in young women include plaque-related MI, microvascular dysfunction or vasospasm, and spontaneous coronary artery dissection. Compared with men, women have greater in-hospital, early and late mortality, as a result of baseline comorbidities. Post-AMI women have lower referral to cardiac rehabilitation with more dropouts, lower levels of physical activity, and poorer improvements in health status compared with men, with higher inflammatory levels at 1-year from index presentation. Future strategies should focus on primary and secondary prevention, adherence, and post-AMI health-related quality of life. This review discusses the current evidence in the epidemiology, diagnosis, and treatment of AMI in young women.

Diabetes and number of years of life lost with and without cardiovascular disease: a multi-state homogeneous semi-Markov model

AIMS

We quantified the impact of type 2 diabetes on incidence of non-fatal cardiovascular disease (CVD) and mortality, considering CVD as a continuum from occurrence of diabetes to the end point, and estimated the 15-year life expectancy with and without CVD.

METHODS

A total of 7239 Iranian adults (3246 men), aged ≥ 30 years, were followed from 1999 to 2014. We applied a multi-state semi-Markov model with three transitions including CVD-free to non-fatal CVD, CVD-free to death and non-fatal CVD to death, and studied the influence of diabetes on each transition rate, stratifying by sex and adjusting for confounders.

RESULTS

Diabetes was significantly associated with increased risk of non-fatal CVD in men [hazard ratio, 1.70 (1.36-3.53)] and women [2.19 (1.74-2.77)], and of all-cause death [2.72 (2.03-3.63) and 1.92 (1.37-2.67) in men and women, respectively]. An increased risk of mortality was found only among diabetic men, when non-fatal CVD was occurred [2.19 (1.36-3.53)]. Men with diabetes experienced first non-fatal CVD and death without CVD 1.7 and 1.4 years, respectively, earlier than those without diabetes; the corresponding values were 1.4 and 0.7 years for women. Moreover, diabetic men lived 1.3 years less than non-diabetic counterparts when non-fatal CVD was occurred.

CONCLUSIONS

Diabetes increased the risk of non-fatal CVD events and all-cause mortality and consequently decreased the number of years lived without CVD. A decrease in LE was found only among diabetic men compared to non-diabetics after non-fatal CVD occurred.
