We aimed to compare clinical outcomes of invasive management with medical management in patients with NSTEMI-CKD. Methods and Results We identified NSTEMI and CKD stages 3, 4, 5, and end-stage renal disease admissions using <i>International Classification of Diseases, Tenth Revision, Clinical Modification</i> (<i>ICD-10-CM</i>) codes from the Nationwide Readmission Database 2016 to 2018. Patients were stratified into invasive and medical management. Primary outcome was mortality (in-hospital and 6 months after discharge). Secondary outcomes were in-hospital postprocedural complications (acute kidney injury requiring dialysis, major bleeding) and postdischarge 6-month safety and major adverse cardiovascular events. Out of 141 052 patients with NSTEMI-CKD, 85 875 (60.9%) were treated with invasive management, whereas 55 177 (39.1%) patients were managed medically. In propensity-score matched cohorts, invasive strategy was associated with lower in-hospital (CKD 3: odds ratio [OR], 0.47 [95% CI, 0.43-0.51]; <i>P</i><0.001; CKD 4: OR, 0.79 [95% CI, 0.69-0.89]; <i>P</i><0.001; CKD 5: OR, 0.72 [95% CI, 0.49-1.06]; <i>P</i>=0.096; end-stage renal disease: OR, 0.51 [95% CI, 0.46-0.56]; <i>P</i><0.001) and 6-month mortality.

However, data on peripartum cardiovascular complications remain limited. Hence, we investigated trends, outcomes, and predictors of cardiovascular complications associated with PCOS diagnosis during delivery hospitalizations in the United States. Methods and Results We used data from the National Inpatient Sample (2002–2019). International Classification of Diseases, Ninth Revision (ICD‐9), or International Classification of Diseases, Tenth Revision (ICD‐10), codes were used to identify delivery hospitalizations and PCOS diagnosis. A total of 71 436 308 weighted hospitalizations for deliveries were identified, of which 0.3% were among women with PCOS (n=195 675). The prevalence of PCOS, and obesity among those with PCOS, increased during the study period. Women with PCOS were older (median, 31 versus 28 years; P<0.01) and had a higher prevalence of diabetes, obesity, and dyslipidemia. After adjustment for age, race and ethnicity, comorbidities, insurance, and income, PCOS remained an independent predictor of cardiovascular complications, including preeclampsia (adjusted odds ratio [OR], 1.56 [95% CI, 1.54–1.59]; P<0.01), eclampsia (adjusted OR, 1.58 [95% CI, 1.54–1.59]; P<0.01), peripartum cardiomyopathy (adjusted OR, 1.79 [95% CI, 1.49–2.13]; P<0.01), and heart failure (adjusted OR, 1.76 [95% CI, 1.27–2.45]; P<0.01), compared with no PCOS. Moreover, delivery hospitalizations among women with PCOS were associated with increased length (3 versus 2 days; P<0.01) and cost of hospitalization ($4901 versus $3616; P<0.01). Conclusions Women with PCOS had a higher risk of preeclampsia/eclampsia, peripartum cardiomyopathy, and heart failure during delivery hospitalizations. Moreover, delivery hospitalizations among women with PCOS diagnosis were associated with increased length and cost of hospitalization. This signifies the importance of prepregnancy consultation and optimization for cardiometabolic health to improve maternal and neonatal outcomes.","PeriodicalId":17189,"journal":{"name":"Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84207401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After careful exclusion of cases with missing values and a prior AF diagnosis, AF prediction models were developed from the derivation cohort of 25 584 patients without AF at baseline. In the internal/external validation cohort of 117 523 patients, the model using 6 clinical features and 5 ECG diagnoses showed the highest performance for 3‐year new‐onset AF prediction (C‐statistic, 0.796 [95% CI, 0.785–0.806]).

Chronic stress may partially explain these disparities. This study identified underlying stress profiles of older US adults, analyzed stress profiles in relation to hypertension and diabetes, examined the distribution of stress profiles by race and ethnicity, and assessed patterns of change in latent classes of stress over time. Methods and Results Latent class analysis was conducted with a nationally representative sample of older US adults who completed 3 waves of the HRS (Health and Retirement Study) (ie, 2010 [n=6863], 2014 [n=4995], and 2018 [n=3089]). Latent classes of stress in 2010 (ie, stress profiles) were identified using 15 indicators of unmet needs within 5 categories (ie, physiological, safety/security, belonging, esteem, and self‐fulfillment). Hypertension and diabetes status were examined as outcomes of latent class membership at 3 time points, and race and ethnicity were examined in association with class membership, adjusting for sociodemographic covariates. Finally, a latent transition analysis examined the stability of latent class membership and racial and ethnic differences in the patterns of stress profiles experienced from 2010 to 2018. Five classes were identified: Generally Unmet Needs (13% of sample), Generally Met Needs (42% of sample), Unmet Self‐Efficacy/Goal Needs (12% of sample), Unmet Financial Needs (20% of sample), and Unmet Social Belonging Needs (13% of sample). Compared with the Generally Met Needs class, the Generally Unmet Needs class had higher odds of hypertension (odds ratio [OR], 1.80; [95% CI, 1.35–2.39]) and diabetes (OR, 1.94; [95% CI, 1.45–2.59]), and the Unmet Financial Needs class had higher odds of diabetes (OR, 1.50; [95% CI, 1.10–2.05]). Non‐Hispanic Black participants compared with non‐Hispanic White participants had higher odds of being members of the Generally Unmet Needs, Unmet Self‐Efficacy/Goal Needs, and Unmet Financial Needs classes (OR, 2.70; [95% CI, 1.59–4.58]; OR, 1.99; [95% CI, 1.15–3.43]; and OR, 4.74; [95% CI, 3.32–6.76], respectively). Class membership remained relatively stable over time, with 93% of participants remaining in Generally Met Needs and 78% of participants remaining in Generally Unmet Needs across time points. Compared with non‐Hispanic White participants, non‐Hispanic Black participants had lower odds of Generally Met Needs class membership at any time point (OR, 0.60; [95% CI, 0.42–0.84]) and had lower odds of moving into the Generally Met Needs class and higher odds of moving into the Unmet Financial Needs class from 2010 to 2014 (OR, 0.33; [95% CI, 0.13–0.86]; and OR, 3.02; [95% CI, 1.16–7.87], respectively).

In addition, there are reports indicating that RhoA‐ROCK (rho associated coiled‐coil containing protein kinase) activation is essential for VEGF (vascular endothelial growth factor)‐mediated angiogenesis, whereas other work suggests VEGF‐antagonistic effects of the RhoA‐ROCK axis. Methods and Results To elucidate this issue, we examined human umbilical vein endothelial cells and human coronary artery endothelial cells after stable overexpression (lentiviral transduction) of constitutively active (G14V/Q63L), dominant‐negative (T19N), or wild‐type RhoA using a series of in vitro angiogenesis assays (proliferation, migration, tube formation, angiogenic sprouting, endothelial cell viability) and a human umbilical vein endothelial cells xenograft assay in immune‐incompetent NOD scid gamma mice in vivo. Here, we report that expression of active and wild‐type RhoA but not dominant‐negative RhoA significantly inhibited endothelial cell proliferation, migration, tube formation, and angiogenic sprouting in vitro. Moreover, active RhoA increased endothelial cell death in vitro and decreased human umbilical vein endothelial cell‐related angiogenesis in vivo. Inhibition of RhoA by C3 transferase antagonized the inhibitory effects of RhoA and strongly enhanced VEGF‐induced angiogenic sprouting in control‐treated cells. In contrast, inhibition of RhoA effectors ROCK1/2 and LIMK1/2 (LIM domain kinase 1/2) did not significantly affect RhoA‐related effects, but increased angiogenic sprouting and migration of control‐treated cells. In agreement with these data, VEGF did not activate RhoA in human umbilical vein endothelial cells as measured by a Förster resonance energy transfer–based biosensor. Furthermore, global transcriptome and subsequent bioinformatic gene ontology enrichment analyses revealed that constitutively active RhoA induced a differentially expressed gene pattern that was enriched for gene ontology biological process terms associated with mitotic nuclear division, cell proliferation, cell motility, and cell adhesion, which included a significant decrease in VEGFR‐2 (vascular endothelial growth factor receptor 2) and NOS3 (nitric oxide synthase 3) expression. Conclusions Our data demonstrate that increased RhoA activity has the potential to trigger endothelial dysfunction and antiangiogenic effects independently of its well‐characterized downstream effectors ROCK and LIMK.","PeriodicalId":17189,"journal":{"name":"Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80458402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods and Results We conducted a systematic search of Embase, MEDLINE, and Cochrane Central Register of Controlled Trials databases to identify studies comparing outcomes between patients requiring resheathing/repositioning during TAVI and those who did not. Random‐effects meta‐analyses were used to estimate the association of resheathing compared with no resheathing with clinical outcomes after TAVI. Seven studies including 4501 participants (pooled mean age, 80.9±7.4 years; 54% women; and 1374 [30.5%] patients requiring resheathing/repositioning) were included in this study. No significant differences between the 2 groups were identified with regards to safety: 30‐day mortality (n=3125; odds ratio [OR], 0.74 [95% confidence interval [CI], 0.41–1.33]; I 2=0%), stroke (n=4121; OR, 1.09 [95% CI, 0.74–1.62]; I 2=0%), coronary obstruction (n=3000; OR, 2.35 [95% CI, 0.17–33.47]; I 2=75%), major vascular complications (n=3125; OR, 0.92 [95% CI, 0.66–1.33]; I 2=0%), major bleeding (n=3125; OR, 1.13 [95% CI, 0.94–2.01]; I 2=39%), acute kidney injury (n=3495; OR, 1.30 [95% CI, 0.64–2.62]; I 2=44%), and efficacy outcomes: device success (n=1196; OR, 0.77 [95% CI, 0.51–1.14]; I 2=0%), need for a second valve (n=3170; OR, 2.86 [95% CI, 0.96–8.48]; I 2=62%), significant (moderate or higher) paravalvular leak (n=1151; OR, 1.53 [95% CI, 0.83–2.80]; I 2=0%), and permanent pacemaker implantation (n=1908; OR, 1.04 [95% CI, 0.68–1.57]; I 2=58%).

As it is rare, short‐term mortality is difficult to use as a primary outcome for clinical studies. We proposed “ICU‐30” as a binary composite “poor” outcome consisting of: (1) mortality within 30 days, (2) intensive care unit (ICU) admission ≥30 days, or (3) ICU readmission before day 30. To measure the utility of this composite, we assessed its prognostic properties for 6‐ and 12‐month mortality. Methods and Results This was a retrospective single‐center cohort study of neonates requiring cardiopulmonary bypass between 2013 and 2020. Mortality among patients with and without the ICU‐30 outcome was compared using log‐rank tests and Cox regression. Areas under the receiver operating characteristic curves assessed the ability of the composite to predict 12‐month mortality. In 887 neonates, 232 (26.2%) experienced the ICU‐30 outcome, with more prolonged ICU stays and readmissions (both ≥9%) than 30‐day mortality (4.2%). ICU‐30 was associated with higher rates of 6‐ and 12‐month mortality (log‐rank P<0.001) and predicted 12‐month mortality with area under the receiver operating characteristic of 0.81 (95% CI, 0.77–0.85). In 30‐day survivors, both prolonged ICU stay (hazard ratio, 12.3; 95% CI, 6.70–22.7; P<0.001) and ICU readmission (hazard ratio, 2.99; 95% CI, 1.17–7.63; P=0.02) were associated with 12‐month mortality. Conclusions ICU‐30, a composite outcome of mortality, ICU length of stay, or ICU readmission by 30 days was associated with 6‐ and 12‐month mortality in neonates requiring cardiopulmonary bypass.

This work investigated the effects of mesenchymal stem cells (MSCs)–secreted EVs–derived miR‐200b‐3p on cardiomyocyte apoptosis and inflammatory response after myocardial infarction (MI) through targeting BCL2L11 (Bcl‐2–like protein 11) . Methods and Results EVs from MSCs were isolated and identified. EVs from MSCs with transfection of miR‐200b‐3p for overexpression were injected into MI mice. The effect of miR‐200b‐3p on cardiac function, infarction area, myocardial fibrosis, cardiomyocyte apoptosis, and inflammatory response was determined in MI mice. The targeting relationship between miR‐200b‐3p and BCL2L11 was verified, and the interaction between BCL2L11 and NLR family pyrin domain containing 1 (NLRP1) was also verified. MI mice were injected with an overexpressing BCL2L11 lentiviral vector to clarify whether BCL2L11 can regulate the effect of miR‐200b‐3p on MI mice. EVs from MSCs were successfully extracted. MSCs‐EVs improved cardiac function and reduced infarction area, apoptosis of cardiomyocytes, myocardial fibrosis, and inflammation in MI mice. Upregulation of miR‐200b‐3p further enhanced the effects of MSCs‐EVs on the myocardial injury of MI mice. BCL2L11 was targeted by miR‐200b‐3p and bound to NLRP1. Upregulation of BCL2L11 negated the role of miR‐200b‐3p–modified MSCs‐EVs in MI mice. Conclusions A summary was obtained that miR‐200b‐3p–encapsulated MSCs‐EVs protect against MI‐induced apoptosis of cardiomyocytes and inflammation via suppressing BCL2L11.","PeriodicalId":17189,"journal":{"name":"Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79136178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
