ABSTRACT

OBJECTIVE: To evaluate contemporary national trends of morbidity, mortality, and healthcare utilization in patients with mitral regurgitation (MR) and co-existing chronic liver disease (CLD) undergoing transcatheter mitral valve repair (TMVR). METHODS: The National Inpatient Sample (NIS) was used to assess trends in patients undergoing TMVR between January 2012 and December 2017. Propensity match analysis was done to compare it to subjects without underlying CLD. Logistic regression analysis was used to identify predictors of in-hospital mortality. RESULTS: Of 15,270 patients undergoing TMVR, 569 (3.7%) had coexisting CLD. Patients with CLD had a higher proportion of males (61.3 vs 52.6%; p < .01), congestive heart failure (6.9 vs 1.0%; p < .01), renal failure (42.2 vs 36.7%; p < .01), and peripheral vascular disease (19.3 vs 12.5%; p < .01). After propensity matching subjects with CLD had significantly higher hospital mortality (19.8 vs 4.6%; p < .01), acute kidney injury (46.1 vs 37.8%; p < .01), cardiogenic shock (25.4 vs 12.1%; p < .01), mechanical ventilation (26.3 vs 14.0; p < .01), pneumothorax (6.6 vs <2%.; p < .01), length of stay (5 vs 9 days), and average cost of hospitalization (209,573 vs 250,587 $; p < .01). Over the years, in-hospital mortality in patients receiving TMVR has improved in both patients with (from 33.3 in 2013 to 22.2% in 2017) and without CLD (from 2.7 in 2011 to 1.6% in 2017). CONCLUSION: Patients with MR undergoing TMVR, with coexisting CLD bear substantially higher comorbidities, complication rates, and inpatient mortality compared with those without CLD. A favorable temporal trend of in-hospital mortality among these subjects is noteworthy.

ABSTRACT

OBJECTIVE: To assess contemporary national trends of comorbidities, outcomes, and health care resource utilization in patients with aortic stenosis (AS) and end-stage renal disease (ESRD) undergoing transcatheter and surgical aortic valve replacement (TAVR and SAVR). METHODS AND RESULTS: The National-Inpatient-Sample was used to study trends in patients with AS and ESRD undergoing TAVR and SAVR between January 2012 and December 2017. Of 12,550 patients, 5,735 underwent TAVR and 6,815 underwent SAVR. Over the years, the utilization of SAVR declined (from 82.0 to 37.7%); and increased for TAVR (from 18.0 to 62.3%; p < .001). Patients receiving TAVR were older (74.6 [9.1] vs. 66.8 years [9.1]), had a higher proportion of females (37.1 vs. 32.5%), Caucasians (68.7 vs. 60.9%) and Asian /Pacific Islanders (3.1 vs. 2.7%; p < .001 for all). The TAVR patients, despite having higher comorbidity burden (anemia, coronary artery disease, chronic pulmonary disease, congestive heart failure, cerebrovascular disease, and peripheral vascular disease) had lower inpatient mortality and complications (ST-elevation myocardial infarction, pneumonia, pneumothorax, pulmonary embolism, cardiogenic shock, cardiac arrest, and need for mechanical ventilators and vasopressors). The median length of stay (13.9-6.5 days; p < .001) and cost of stay ($311,538.16 to $255,693.40; p < .001) reduced with TAVR; but remained unchanged with SAVR. Higher proportion of patients was discharged home after TAVR vs. SAVR. CONCLUSION: Among patients with AS and ESRD, despite providing therapy to subjects with higher comorbidity burden, TAVR was associated with lower inpatient mortality, complications, length of stay, cost of care, and higher home disposition rates when compared with SAVR.

ABSTRACT

Evidence-based recommendations for clinical practice are intended to help health care providers and patients make decisions, minimize inappropriate practice variation, promote effective resource use, improve clinical outcomes, and direct future research. The Society for Cardiovascular Angiography and Interventions (SCAI) has been engaged in the creation and dissemination of clinical guidance documents since the 1990s. These documents are a cornerstone of the society's education, advocacy, and quality improvement initiatives. The publications committee is charged with oversight of SCAI's clinical documents program and has created this manual of standard operating procedures to ensure consistency, methodological rigor, and transparency in the development and endorsement of the society's documents. The manual is intended for use by the publications committee, document writing groups, external collaborators, SCAI representatives, peer reviewers, and anyone seeking information about the SCAI documents program.

ABSTRACT

The mortality effects and risk-benefit profile of low dose rivaroxaban (2.5 mg twice daily) in patients with coronary heart disease are not completely understood. Five randomized controlled trials (26,110 patients) were selected using PubMed and Cochrane library till April 2019. The background antiplatelet therapy was aspirin in 3 trials, P2Y12 inhibitor in 1 trial, and in 1 trial 65% patients received aspirin and 35% were on dual antiplatelet therapy (DAPT). The outcomes of interest were cardiovascular mortality, all-cause mortality, myocardial infarction (MI), stroke and major bleeding events. Random effects hazard ratios (HR) with 95% confidence intervals (CI) were calculated. Low dose rivaroxaban did not reduce the risk of cardiovascular mortality (HR 0.90, 95% CI 0.73-1.11, P = 0.34) or all-cause mortality (HR 0.91, 95% CI 0.74-1.12, P = 0.38) compared with control. However, low dose rivaroxaban was associated with reduction in MI (HR 0.85, 95% CI 0.73-0.99, P = 0.04), and stroke (HR 0.59, 95%CI 0.48-0.73, P < 0.001) at the expense of major bleeding (HR 1.64, 95% CI 1.39-1.94, P < 0.001) compared with control. These effects did not vary according to acute coronary syndrome or stable coronary heart disease (P-interaction > 0.05). The use of low dose rivaroxaban in patients with coronary heart disease predominantly receiving antiplatelet monotherapy did not reduce cardiovascular or all-cause mortality. The benefits of preventing MI and stroke were balanced by increased risk of major bleeding.

ABSTRACT

Background: The role of nutritional supplements and dietary interventions in preventing mortality and cardiovascular disease (CVD) outcomes is unclear. Purpose: To examine evidence about the effects of nutritional supplements and dietary interventions on mortality and cardiovascular outcomes in adults. Data Sources: PubMed, CINAHL, and the Cochrane Library from inception until March 2019; ClinicalTrials.gov (10 March 2019); journal Web sites; and reference lists. Study Selection: English-language, randomized controlled trials (RCTs) and meta-analyses of RCTs that assessed the effects of nutritional supplements or dietary interventions on all-cause mortality or cardiovascular outcomes, such as death, myocardial infarction, stroke, and coronary heart disease. Data Extraction: Two independent investigators abstracted data, assessed the quality of evidence, and rated the certainty of evidence. Data Synthesis: Nine systematic reviews and 4 new RCTs were selected that encompassed a total of 277 trials, 24 interventions, and 992 129 participants. A total of 105 meta-analyses were generated. There was moderate-certainty evidence that reduced salt intake decreased the risk for all-cause mortality in normotensive participants (risk ratio [RR], 0.90 [95% CI, 0.85 to 0.95]) and cardiovascular mortality in hypertensive participants (RR, 0.67 [CI, 0.46 to 0.99]). Low-certainty evidence showed that omega-3 long-chain polyunsaturated fatty acid (LC-PUFA) was associated with reduced risk for myocardial infarction (RR, 0.92 [CI, 0.85 to 0.99]) and coronary heart disease (RR, 0.93 [CI, 0.89 to 0.98]). Folic acid was associated with lower risk for stroke (RR, 0.80 [CI, 0.67 to 0.96]; low certainty), whereas calcium plus vitamin D increased the risk for stroke (RR, 1.17 [CI, 1.05 to 1.30]; moderate certainty). Other nutritional supplements, such as vitamin B6, vitamin A, multivitamins, antioxidants, and iron and dietary interventions, such as reduced fat intake, had no significant effect on mortality or cardiovascular disease outcomes (very low- to moderate-certainty evidence). Limitations: Suboptimal quality and certainty of evidence. Conclusion: Reduced salt intake, omega-3 LC-PUFA use, and folate supplementation could reduce risk for some cardiovascular outcomes in adults. Combined calcium plus vitamin D might increase risk for stroke. Primary Funding Source: None.

ABSTRACT

Background and Purpose- The role of aspirin plus clopidogrel (A+C) therapy compared with aspirin monotherapy in patients presenting with acute ischemic stroke (IS) or transient ischemic attack remains uncertain. We conducted this study to determine the optimal period of efficacy and safety of A+C compared with aspirin monotherapy. Methods- Ten randomized controlled trials (15 434 patients) were selected using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) (inception June 2018) comparing A+C with aspirin monotherapy in patients with transient ischemic attack or IS. The primary efficacy outcome was recurrent IS, and the primary safety outcome was major bleeding. The secondary outcomes were major adverse cardiovascular events (composite of stroke, myocardial infarction, and cardiovascular mortality) and all-cause mortality. We stratified analysis based on the short- (≤1 month), intermediate- (≤3 month), and long-term (>3 month) A+C therapy. Effects were estimated as relative risk (RR) with 95% CI. Results- A+C significantly reduced the risk of recurrent IS at short-term (RR, 0.53; 95% CI, 0.37-0.78) and intermediate-term (RR, 0.72; 95% CI, 0.58-0.90) durations. Similarly, major adverse cardiovascular event was significantly reduced by short-term (RR, 0.68; 95% CI, 0.60-0.78) and intermediate-term (RR, 0.76; 95% CI, 0.61-0.94) A+C therapy. However, long-term A+C did not yield beneficial effect in terms of recurrent IS (RR, 0.81; 95% CI, 0.63-1.04) and major adverse cardiovascular events (RR, 0.87; 95% CI, 0.71-1.07). Intermediate-term (RR, 2.58; 95% CI, 1.19-5.60) and long-term (RR, 1.87; 95% CI, 1.36-2.56) A+C regimens significantly increased the risk of major bleeding as opposed to short-term A+C (RR, 1.82; 95% CI, 0.91-3.62). Excessive all-cause mortality was limited to long-term A+C (RR, 1.45; 95% CI, 1.10-1.93). Conclusions- Short-term A+C is more effective and equally safe in comparison to aspirin alone in patients with acute IS or transient ischemic attack.

ABSTRACT

AIM: The objective of this article is to review the contemporary literature on the use of antithrombotic therapy in patients with atrial fibrillation (AF) and coronary artery disease after undergoing percutaneous coronary intervention (PCI). Special consideration was given to the type and duration of therapy, treatment strategies for the elderly (≥65 years of age), and strategies to reduce bleeding. METHODS: Relevant studies were searched through MEDLINE/PubMed, Web of Science, Cochrane Library, ClinicalTrials.gov, and Google Scholar. Of the 236 publications retrieved, 76 were considered relevant including 35 randomized controlled trials, 17 meta-analyses, 16 observational studies, and 8 published major guidelines. RESULTS: Most trials, meta-analyses, and guidelines support 1 month of triple therapy (TT) with an oral anticoagulant (OAC), dual antiplatelet agents (DAPT) with aspirin (ASA)/clopidogrel, and, afterward, dual therapy (DT) with OAC and single antiplatelet agent for an additional 11 months, or alternatively DT alone for 12 months after PCI. Individual consideration is given to the risk and impact of stent thrombosis (ST), thromboembolism, and bleeding. Several trials and meta-analyses have also suggested that shorter DAPT duration (≤6 months) may be safer than longer therapy (≥6 months) when weighing the risk of bleeding with ischemic outcomes, especially with newer generation drug-eluting stents. The selective use of proton-pump inhibitors in patients prone to gastrointestinal bleeding who are subjected to prolonged exposure with TT or DT may be beneficial. In the elderly, the risk of bleeding from TT, compared with DT, outweighs the benefit of reducing ischemic events. CONCLUSIONS: In conclusion, tailoring therapy to the individual patient is recommended considering the ischemic and bleeding risk as well as the risk of thromboembolism. For most patients with AF, 1 month of TT and subsequently DT for additional 11 months are recommended.

ABSTRACT

Aims: To assess whether continuous positive airway pressure (CPAP) therapy reduces major adverse cardiovascular events (MACE) in patients with moderate-to-severe obstructive sleep apnoea (OSA). Methods and results: A total of 235 articles were recovered using MEDLINE, EMBASE and Cochrane library (inception-December 2016) and references contained in the identified articles. Seven randomized controlled trials (RCTs) were selected for final analysis. Analysis of 4268 patients demonstrated non-significant 26% relative risk reduction in MACE with CPAP [risk ratio (RR) 0.74; 95% confidence interval (CI) 0.47-1.17; P = 0.19, I2 = 48%]. A series of sensitivity analyses suggested that increased CPAP usage time yielded significant risk reduction in MACE. and stroke. Subgroup analysis revealed that CPAP adherence time ≥4 hours (h)/night reduced the risk of MACE by 57% (RR 0.43; 95% CI 0.23-0.80; P = 0.01, I2 = 0%). CPAP therapy showed no beneficial effect on myocardial infarction (MI), all-cause mortality, atrial fibrillation/flutter (AF), or heart failure (HF) (P > 0.05). CPAP had positive effect on mood and reduced the daytime sleepiness [Epworth Sleepiness Scale (ESS): mean difference (MD) -2.50, 95% CI - 3.62, -1.39; P < 0.001, I2 = 81%]. Conclusion: CPAP therapy might reduce MACE and stroke among subjects with CPAP time exceeding 4 h/night. Additional randomized trials mandating adequate CPAP time adherence are required to confirm this impression.

ABSTRACT

OBJECTIVE: To investigate the safety and efficacy of percutaneous coronary interventions (PCI) versus coronary artery bypass graft (CABG) surgery for left main coronary artery (LMCA) disease. METHODS: Six randomised controlled trials (RCTs) were reviewed by searching PubMed/Medline, Embase and the Cochrane Library. Estimates were pooled according to random effects model. Binary outcomes were reported as risk ratio (RR) and continuous outcomes were reported as mean difference (MD) with 95% confidence interval (CI). RESULTS: 3794 patients were randomised into PCI and CABG arms. Mean age of the total population was 64.7 years, 74.4% were male and mean Logistic EURO score (LES) was 2.9. When compared with CABG, patients treated with PCI had reduced risk of major adverse cardiovascular events (MACE) at 30 days: (RR: 0.55; 95% CI, 0.41-0.75; p<0.001; I2=0) but similar risk at 1year (RR: 1.15; 95% CI, 0.92-1.45; p=0.22; I2=0). Five years MACE rates favoured CABG (RR: 1.32; 95% CI, 1.13-1.53; p<0.001; I2=0) driven by a higher rate of target vessel revascularisation (TVR) (RR: 1.71; 95%CI, 1.38-2.12; p<0.001; I2=0) and myocardial infarction (MI) (RR: 1.97; 95%CI, 1.28-3.04; p<0.001; I2=22). Percutaneous coronary intervention was comparatively a safer procedure with lower rates of periprocedural adverse events including MI, stroke, bleeding events and need for blood transfusions. CONCLUSION: Percutaneous coronary intervention reduced MACE at 30days with comparable MACE at 1year. However, CABG was a more effective modality when considering mid- to long-term outcomes. PCI is a safer procedure with regards to periprocedural adverse events.

ABSTRACT

Acute ST-elevation myocardial (STEMI) infarction due to septic embolism is rare and management strategies differ from those applied to atherothrombotic STEMI. A 70-year-old male with aortic valve endocarditis and persistent bacteremia developed acute inferior wall STEMI due to septic embolism. Due to inferior STEMI accompanied by hemodynamic instability, coronary angiography and primary PCI (stenting) to a totally occluded right coronary artery (RCA) was performed. Despite excellent immediate angiographic results and hemodynamic stabilization, repeat angiogram two weeks later showed mycotic aneurysms at the site of stent placement. Patient later suffered from intracranial hemorrhage and splenic infarct and had worsening aortic regurgitation, prompting surgical aortic valve replacement with bypass of the RCA. Despite aggressive medical, interventional and surgical management, he expired four weeks after the surgery. Selection of an optimal revascularization strategy in this scenario is unclear with a potential harm from standard therapies. We have reviewed prior reports and summarized results in a tabular form.

ABSTRACT

Membrane pathology tends to complicate the postprocedural course of open sinus lift by ostio-meatal complex (OMC) obstruction and consequent acute sinusitis. The objective of this study was to evaluate the outcome of subjects with considerable sinus membrane pathology undergoing maxillary sinus floor augmentation and simultaneous implant placement using the minimal invasive antral membrane balloon elevation (MIAMBE) method. This study was a retrospective chart review of MIAMBE procedures performed in the presence of significant sinus membrane pathology. Sixteen patients with maxillary sinus membrane thickening in well-ventilated OMC as determined by dental computerized tomography underwent sinus augmentation and simultaneous implant placement using the MIAMBE technique. All 16 procedures were successfully concluded without significant procedural or postprocedural complications or implant failure. Post MIAMBE membrane pathology regressed or disappeared in 8 patients (50%) or remained unchanged in 6 patients (37.5%), while in 2 patients the sinus membrane pathology was limited to evaluation by periapical X rays. Sinus augmentation using the MIAMBE technique can be performed safely in asymptomatic patients in the presence of sinus membrane pathology if the OMC is not obstructed. In a significant proportion of these cases, complete resolution of the membrane pathology after MIAMBE is observed. When compared to open sinus lift, OMC obstruction is less likely to occur when employing the MIAMBE method.

ABSTRACT

OBJECTIVES: The purpose of this study was to compare the efficacy and safety of intracoronary (IC) nitroprusside and intravenous adenosine (IVA) for assessing fractional flow reserve (FFR). BACKGROUND: IV infusion of adenosine is a standard method to achieve a coronary hyperemia for FFR measurement. However, adenosine is expensive, causes multiple side effects, and is contraindicated in patients with reactive airway disease. Sodium nitroprusside (NTP) is a strong coronary vasodilator but its efficacy and safety for assessing FFR is not well established. METHODS: We compared FFR response and side effects profile of IC NTP and IVA. Bolus of NTP at a dose of 100 µg and IVA (140 µg/kg/min) were used to achieve coronary hyperemia. RESULTS: We evaluated 75 lesions in 53 patients (60% male) mean age 61.6 ± 13.9 years. Mean FFR after NTP was similar to FFR after adenosine (0.836 ± 0.107 vs. 0.856 ± 0.106; P = 0.26; r = 0.91, P < 0.001). NTP induced maximal stable hyperemia within 10 sec (mean: 6.4 ± 1) which lasted consistently between 38 and 60 sec (mean 51 ± 7.5). NTP caused significant (14%), but asymptomatic decrease in mean blood pressure which returned to baseline within 60 sec. Adenosine caused shortness of breath in 26%, headache and flushing in 19%, and transient second degree heart block in 6% of patients. No adverse symptoms were reported after NTP. CONCLUSIONS: IC NTP is as effective as IVA for measuring FFR. NTP is better tolerated by patients. Since NTP is inexpensive, readily available, well tolerated, and safe, it may be a better choice for FFR assessment.

ABSTRACT

Stress-induced cardiomyopathy (SIC) is characterized by reversible left ventricular (LV) systolic dysfunction, which appears to be triggered by an intense, stressful event in the absence of significant coronary artery disease. It manifests typically with transient left ventricular wall motion abnormalities (WMA) involving the apical and/or mid-ventricular myocardial segments, associated with minimal troponin rise (<5 ng/ml), and typical EGG changes. Described are 3 cases of stress-induced cardiomyopathy with atypical distribution of wall motion abnormalities. Possible contributing mechanisms to the pathogenesis and the variability in WMA are discussed.

ABSTRACT

Described is challenging trans-catheter aortic valve replacement (TAVR) procedure done via tortuous iliofemoral access with prior endovascular aneurysm repair. Detailed pre-procedural planning enabled the operators to overcome the challenges while employing the following 4 strategies: Although trans-EVAR TAVR remains somewhat unpredictable, especially these 4 strategies may simplify and reduce the inherent failure rate of such procedures.

ABSTRACT

Background Sodium-glucose cotransporter-2 (SGLT2) inhibitors reduce atherosclerotic cardiovascular disease (ASCVD) events in patients with prior ASCVD and type 2 diabetes; however, this benefit is uncertain in patients without established ASCVD. Methods and Results Large-scale cardiovascular outcome randomized controlled trials or their prespecified subgroup analyses were selected, evaluating SGLT2 inhibitors versus placebo for primary prevention of ASCVD (inception, March 2023). The primary outcome was atherosclerotic major adverse cardiovascular events (MACEs), which was a composite of cardiovascular mortality, myocardial infarction, and stroke. The secondary outcomes were individual components of MACEs and all-cause mortality. The outcomes were reported as random-effect relative risk (RR) with a 95% CI. This analysis, comprising 23 987 patients enrolled in 5 randomized controlled trials with a mean follow-up duration of ≈135 weeks, found no significant reduction in atherosclerotic MACEs with SGLT2 inhibitors in comparison to placebo (RR, 0.85 [95% CI, 0.71-1.01]; P=0.07; I2=44). There were no significant differences in cardiovascular mortality (RR, 0.93 [95% CI, 0.77-1.14]; P=0.50; I2=0), myocardial infarction (RR, 0.88 [95% CI, 0.69-1.11]; P=0.28; I2=23), and stroke (RR, 0.84 [95% CI, 0.62-1.16]; P=0.29; I2=46). SGLT2 inhibitors significantly improved all-cause mortality (RR, 0.85 [95% CI, 0.72-1.0]; P=0.04; I2=23). On subgroup analyses, the use of SGLT2 inhibitors led to significant reductions in MACEs (RR, 0.74 [95% CI, 0.61-0.89]; P=0.001), myocardial infarction (RR, 0.67 [95% CI, 0.47-0.97]; P=0.03), and stroke (RR, 0.61 [95% CI, 0.41-0.91]; P=0.01) primarily in patients with chronic kidney disease along with type 2 diabetes, whereas these benefits were not observed in patients with type 2 diabetes without chronic kidney disease. Conclusions SGLT2 inhibitors significantly reduced atherosclerotic MACEs in subjects having both chronic kidney disease and type 2 diabetes without established ASCVD.

ABSTRACT

The association of repeat revascularization after percutaneous coronary intervention (PCI) with mortality is uncertain. To assess the association of repeat revascularization after PCI with mortality in patients with coronary artery disease (CAD). We identified randomized controlled trials comparing PCI with coronary artery bypass graft (CABG) or optimal medical therapy (OMT) using electronic databases through January 1, 2022. We performed a random-effects meta-regression between repeat revascularization rates after PCI (absolute risk difference [%] between PCI and CABG or OMT) with the relative risks (RR) of mortality. We assessed surrogacy of repeat revascularization for mortality using the coefficient of determination (R2), with threshold of 0.80. In 33 trials (21,735 patients), at median follow-up of 4 (2-7) years, repeat revascularization was higher after PCI than CABG [RR: 2.45 (95% confidence interval, 1.99-3.03)], but lower vs OMT [RR: 0.64 (0.46-0.88)]. Overall, meta-regression showed that repeat revascularization rates after PCI had no significant association with all-cause mortality [RR: 1.01 (0.99-1.02); R2=0.10) or cardiovascular mortality [RR: 1.01 (CI: 0.99-1.03); R2=0.09]. In PCI vs CABG (R2=0.0) or PCI vs OMT trials (R2=0.28), repeat revascularization did not meet the threshold for surrogacy for all-cause or cardiovascular mortality (R2=0.0). We observed concordant results for subgroup analyses (enrollment time, follow-up, sample size, risk of bias, stent types, and coronary artery disease), and multivariable analysis adjusted for demographics, comorbidities, risk of bias, MI, and follow-up duration. In summary, this meta-regression did not establish repeat revascularization after PCI as a surrogate for all-cause or cardiovascular mortality.

ABSTRACT

Atrophic edentulous anterior maxilla is a challenging site for implant placement and has been successfully treated surgically by anterior maxillary osteoplasty. This procedure is associated with considerable discomfort, morbidity, and cost-and consequently reduced patient acceptance. The efficacy and safety of minimally invasive bone augmentation of the posterior maxilla has not been extended thus far to the anterior subnasal maxilla. We present 2 representative cases in which minimally invasive subnasal floor elevation was performed along with minimally invasive antral membrane balloon elevation. Both segments underwent bone grafting and implant placement during the same sitting. Minimally invasive anterior maxilla bone augmentation appears to be feasible. Designated instruments for alveolar ridge splitting and nasal mucosa elevation are likely to further enhance this initial favorable experience.

ABSTRACT

V-stenting (VS) and simultaneously kissing stents (SKS) upfront 2-stent strategies for treating large diameter bifurcations and especially distal left main coronary artery (LMCA) disease. Former teaching suggests that the minimal requirements for VS and SKS requires 8F guiding catheters or 7.5F sheathless guide. Presented is the "2-Step refinement" of SKS and VS that can be executed via conventional 6F guide without any additional equipment. In view of the simplicity and suitability for unstable subjects with acute coronary syndromes; "2 Step SKS and VS" should be in the armamentarium of all advanced interventionalists.

ABSTRACT

Background Evaluating premature (<65 years of age) mortality because of acute myocardial infarction (AMI) by demographic and regional characteristics may inform public health interventions. Methods and Results We used the Centers for Disease Control and Prevention's WONDER (Wide-Ranging Online Data for Epidemiologic Research) death certificate database to examine premature (<65 years of age) age-adjusted AMI mortality rates per 100 000 and average annual percentage change from 1999 to 2019. Overall, the age-adjusted AMI mortality rate was 13.4 (95% CI, 13.3-13.5). Middle-aged adults, men, non-Hispanic Black adults, and rural counties had higher mortality than young adults, women, NH White adults, and urban counties, respectively. Between 1999 and 2019, the age-adjusted AMI mortality rate decreased at an average annual percentage change of -3.4 per year (95% CI, -3.6 to -3.3), with the average annual percentage change showing higher decline in age-adjusted AMI mortality rates among large (-4.2 per year [95% CI, -4.4 to -4.0]), and medium/small metros (-3.3 per year [95% CI, -3.5 to -3.1]) than rural counties (-2.4 per year [95% CI, -2.8 to -1.9]). Age-adjusted AMI mortality rates >90th percentile were distributed in the Southern states, and those with mortality <10th percentile were clustered in the Western and Northeastern states. After an initial decline between 1999 and 2011 (-4.3 per year [95% CI, -4.6 to -4.1]), the average annual percentage change showed deceleration in mortality since 2011 (-2.1 per year [95% CI, -2.4 to -1.8]). These trends were consistent across both sexes, all ethnicities and races, and urban/rural counties. Conclusions During the past 20 years, decline in premature AMI mortality has slowed down in the United States since 2011, with considerable heterogeneity across demographic groups, states, and urbanicity. Systemic efforts are mandated to address cardiovascular health disparities and outcomes among nonelderly adults.

ABSTRACT

OBJECTIVES: Recent heart failure studies have suggested that inflammatory and immune system activation are associated with increased levels of cytokines, chemokines and inflammatory proteins during acutely decompensated heart failure. The objectives of this substudy were to evaluate the role of neurohormonal and inflammatory activation in the pathogenesis and outcome of acute heart failure (AHF) and the correlation between biomarker levels and clinical outcomes. METHODS: Serum levels of B-type natriuretic peptide-32 (BNP-32), endothelin-1 (ET-1), norepinephrine, troponins I and T, C-reactive protein (CRP), von Willebrand factor, plasminogen activator inhibitor-1, interleukin-6 (IL-6) and tissue plasminogen activator (TPA) were measured at baseline, 24 and 48 h and 7 and 30 days in 112 patients with AHF recruited to the Value of Endothelin Receptor Inhibition with Tezosentan in Acute Heart Failure Study neurohormonal substudy. RESULTS: On univariable analysis, CRP, BNP and ET-1 were predictive of worsening heart failure by day 30; when considered together, only CRP and BNP were significantly associated with this outcome. On adjustment for age, baseline blood pressure, serum sodium and serum creatinine, only age and BNP remained significant. CRP, IL-6 and TPA levels were significantly correlated with 180-day mortality on univariable analysis. CONCLUSION: Circulating markers of inflammation may be useful in gauging prognosis in patients with AHF.
