Despite advances in drug and device technology, health care delivery, and research infrastructure, cardiogenic shock (CS) continues to have nearly 50% in‐hospital mortality. In patients with CS, both the initial severity of Society for Cardiovascular Angiography and Intervention CS and its subsequent trajectory predicts the clinical outcomes. Accordingly, delayed initial recognition and failure to escalate or deescalate treatment can significantly affect the outcomes of CS. Traditional assessment methods, with the exception of blood pressure measurement, require a high index of suspicion and frequent reassessment by the clinical team. Electronic medical record‐based detection has been successfully implemented in acute and critical care patients with septic shock and acute kidney injury. In CS, electronic medical record‐based studies have largely focused on using models to predict outcomes in patients with CS, with limited data on electronic medical record‐based tools to assist with either predicting CS or providing real time alerts when escalation or de‐escalation might be indicated. Early detection of CS may be associated with detection of earlier Society for Cardiovascular Angiography and Intervention stages of CS and potentially prevent deterioration to higher stages. In this review, we seek to highlight a blueprint for electronic medical record‐based detection of CS that focuses on reproducibility, convenience, clinical decision support, and research aspects.

ABSTRACT There are limited and conflicting data on sex and urban‐rural disparities in outcomes of patients with pulmonary embolism (PE) in the reproductive age group. Our object was to assess sex disparities in the reproductive age group cohort. All adult non‐elective admissions in the reproductive age group (18−49 years) with a primary diagnosis of PE and with no missing sex/age data were identified using the National Inpatient Sample. Females and males were stratified into rural and urban location based on hospital information. Outcomes of interest included in‐hospital mortality, complication rates, variations in management, total hospitalization costs, and length of stay. During 01/01/2016 to 12/31/2020, 180,898 PE admissions aged 18−49 years were identified (rural—12,319 [6.8%]). Females comprised 54.8% and 55.1% of the rural and urban cohorts, respectively. Overall, compared to males, females in urban and rural regions had largely comparable rates of definitive PE interventions, except lower rates of catheter directed therapy (4.7 vs. 3.6%, p < 0.001) in females admitted to urban hospitals. Despite younger age, higher comorbidity, and lower utilization of PE interventions, females in both regions had similar unadjusted in‐hospital mortality (rural 1.1% vs. 1.0%; p = 0.93 and urban 1.8% vs. 1.7%; p = 0.78) and hospitalization costs compared to males. In conclusion, females of reproductive age group had comparable in‐hospital outcomes to males in both urban and rural areas. Females in urban areas had lower utilization of advanced PE interventions, potentially indicating selective management strategies in different settings.

Background TAILOR‐PCI (Tailored Antiplatelet Initiation to Lessen Outcomes due to decreased Clopidogrel Response After Percutaneous Coronary Intervention) studied genotype‐guided selection of antiplatelet therapy after percutaneous coronary intervention versus conventional therapy with clopidogrel. The presence of CYP2C19 loss‐of‐function alleles in patients treated with clopidogrel may be associated with increased risk for ischemic events. We report a prespecified sex‐specific analysis of genotyping and associated cardiovascular outcomes from this study. Methods and Results Associations between sex and major adverse cardiac events (MACE: cardiovascular death, myocardial infarction, stroke, stent thrombosis, and severe recurrent ischemia) and Bleeding Academic Research Consortium (BARC) bleeding at 12 months were analyzed using Cox proportional‐hazards models. Among 5276 randomized patients, loss‐of‐function carriers were observed in ≈36% of both sexes, and >80% of carriers were heterozygotes. At 12 months, after adjustment for baseline differences, risks of MACE (HR , 1.28 [0.97 to 1.68]; P =0.088) and BARC bleeding (hazard ratio [HR], 1.36 [0.91 to 2.05]; P =0.14) were comparable among women and men. There were no significant interactions between sex and treatment strategy for MACE interaction P value ( P int =0.59) or BARC bleeding ( P int =0.47) nor for sex and genotype (MACE P int =0.15, and BARC bleeding P int =0.60). Conclusions CYP2C19 loss‐of‐function alleles were present in ≈1 in 3 women and men. Women had similar adjusted risks of MACE and bleeding as men following percutaneous coronary intervention. Genotype‐guided therapy did not significantly reduce the risk of MACE or bleeding relative to conventional therapy for both sexes.

AbstractBackgroundThere is a paucity of data regarding the sex‐related differences in the trends and outcomes of trans‐septal transcatheter mitral valve replacement (TS‐TMVR).MethodsThe Nationwide Readmissions Database (2015–2018) was queried for admissions for TS‐TMVR. Propensity matched analysis was conducted to compare outcomes with hospitalizations for TS‐TMVR among women versus men. The main study outcome was in‐hospital mortality.ResultsOur final analysis included 2063 hospitalizations for TS‐TMVR; of whom, 58.1% were women. The proportion of women among those undergoing TS‐TMVR increased from 50% in 2015 to 60.2% in 2018 (Ptrend = 0.04). Compared with men, women undergoing TS‐TMVR were slightly younger, and had a distinct profile of comorbidities. After matching, there was no significant difference in in‐hospital mortality among women versus men undergoing TS‐TMVR (7.8% vs. 6.1%, OR = 1.30; 95% CI: 0.79–2.13). Subgroup analyzes showed an interaction toward higher mortality with women versus men among patients with CKD (Pinteraction = 0.07). There were no significant differences between women and men in in‐hospital complications or length of stay after TS‐TMVR. Compared with men, women undergoing TS‐TMVR were more likely to be discharged to a nursing facility (17.7% vs. 11.5%, p = 0.01) and had higher rates of 30‐day readmissions (22.4% vs. 13.6%, p = 0.01).ConclusionThis nationwide analysis showed an increase in the proportion of women among patients undergoing TS‐TMVR during the study years. There were no differences in in‐hospital mortality, in‐hospital complications, or length of stay between both sexes following TS‐TMVR. Women were more likely to be discharged to nursing facilities and had higher rates of readmission at 30 days even after propensity matching.

Background Elderly patients have a higher burden of comorbidities that influence clinical outcomes. We aimed to compare in‐hospital outcomes in patients ≥80 years old to younger patients, and to determine the factors associated with increased risk of major adverse events (MAE) after left atrial appendage closure. Methods and Results The National Inpatient Sample was used to identify discharges after left atrial appendage closure between October 2015 and December 2018. The primary outcome was in‐hospital MAE defined as the composite of postprocedural bleeding, vascular and cardiac complications, acute kidney injury, stroke, and death. A total of 6779 hospitalizations were identified, of which, 2371 (35%) were ≥80 years old and 4408 (65%) were <80 years old. Patients ≥80 years old experienced a higher rate of MAE compared with those aged <80 years old (6.0% versus 4.6%, P =0.01), and this difference was driven by a numerically higher rate of cardiac complications (2.4% versus 1.8%, P =0.09) and death (0.3% versus 0.1%, P =0.05) among individuals ≥80 years old. In patients ≥80 years old, higher odds of in‐hospital MAE were observed in women (1.61‐fold), and those with preprocedural congestive heart failure (≈2‐fold), diabetes (≈1.5‐fold), renal disease (≈2.6‐fold), anemia (≈2.7‐fold), and dementia (≈5‐fold). In patients <80 years old, a higher risk of in‐hospital MAE was encountered among women (≈1.4‐fold) and those with diabetes (≈1.3‐fold), renal disease (≈2.6‐fold), anemia (≈2‐fold), and dyslipidemia (≈1.2‐fold). Conclusions Patients ≥80 years old had higher rates of in‐hospital MAE compared with patients aged <80 years old. Female sex and the presence of heart failure, diabetes, renal disease, and anemia were factors associated with in‐hospital MAE among both groups.

Background— A significant proportion of patients requiring aortic valve replacement (AVR) have undergone prior coronary artery bypass grafting (CABG). Reoperative heart surgery is associated with increased risk. Data on relative utilization and comparative outcomes of transcatheter (TAVR) versus surgical AVR (SAVR) in patients with prior CABG are limited. Methods and Results— We queried the 2012 to 2014 National Inpatient Sample databases to identify isolated AVR hospitalizations in adults with prior CABG. In-hospital outcomes of TAVR versus SAVR were compared using propensity-matched analysis. Of 147 395 AVRs, 15 055 (10.2%) were in patients with prior CABG. The number of TAVRs in patients with prior CABG increased from 1615 in 2012 to 4400 in 2014, whereas the number of SAVRs decreased from 2285 to 1895 ( P trend <0.001). There were 3880 records in each group in the matched cohort. Compared with SAVR, TAVR was associated with similar in-hospital mortality (2.3% versus 2.4%; P =0.71) but lower incidence of myocardial infarction (1.5% versus 3.4%; P <0.001), stroke (1.4% versus 2.7%; P <0.001), bleeding complications (10.6% versus 24.6%; P <0.001), and acute kidney injury (16.2% versus 19.3%; P <0.001). Requirement for prior permanent pacemaker was higher in the TAVR cohort, whereas the incidence of vascular complications and acute kidney injury requiring dialysis was similar in the 2 groups. Average length of stay was shorter in patients undergoing TAVR. Conclusions— TAVR is being increasingly used as the preferred modality of AVR in patients with prior CABG. Compared with SAVR, TAVR is associated with similar in-hospital mortality but lower rates of in-hospital complications in this important subset of patients.
