Background: Risk stratifying patients with cardiogenic shock (CS) is a major unmet need. The recently proposed Society for Cardiovascular Angiography and Interventions (SCAI) stages as an approach to identify patients at risk for in-hospital mortality remains under investigation. We studied the utility of the SCAI stages and further explored the impact of hemodynamic congestion on clinical outcomes. Methods: The CS Working Group registry includes patients with CS from 8 medical centers enrolled between 2016 and 2019. Patients were classified by the maximum SCAI stage (B–E) reached during their hospital stay according to drug and device utilization. In-hospital mortality was evaluated for association with SCAI stages and hemodynamic congestion. Results: Of the 1414 patients with CS, the majority were due to decompensated heart failure (50%) or myocardial infarction (MI; 35%). In-hospital mortality was 31% for the total cohort, but higher among patients with MI (41% versus 26%, MI versus heart failure, P <0.0001). Risk for in-hospital mortality was associated with increasing SCAI stage (odds ratio [95% CI], 3.25 [2.63–4.02]) in both MI and heart failure cohorts. Hemodynamic data was available in 1116 (79%) patients. Elevated biventricular filling pressures were common among patients with CS, and right atrial pressure was associated with increased mortality and higher SCAI Stage. Conclusions: Our findings support an association between the proposed SCAI staging system and in-hospital mortality among patient with heart failure and MI. We further identify that venous congestion is common and identifies patients with CS at high risk for in-hospital mortality. These findings provide may inform future management protocols and clinical studies.

Background : Cardiogenic shock occurring in the setting of advanced heart failure (HF-CS) is increasingly common. However, recent studies have focused almost exclusively on acute myocardial infarction related cardiogenic shock. We sought to define clinical, hemodynamic, metabolic, and treatment parameters associated with clinical outcomes among HF-CS patients, using data from the Cardiogenic Shock Working Group (CSWG) Registry. Methods : Patients with HF-CS were identified from the multi-center CSWG registry and divided into 3 outcome categories assessed at hospital discharge: mortality, heart replacement therapy (HRT: durable ventricular assist device [VAD] or orthotopic heart transplant [OHT]), or native heart survival (NHS). Clinical characteristics, hemodynamic, laboratory parameters, drug therapies, acute mechanical circulatory support device (AMCS) utilization, and Society of Cardiovascular Angiography and Intervention (SCAI) stages were compared across the 3 outcome cohorts. Results : Of the 712 HF-CS patients identified, 180 (25.3%) died during their index admission, 277 (38.9%) underwent HRT (durable VAD or OHT), and 255 (35.8%) experienced NHS without HRT. Patients who died had the highest right atrial pressure and heart rate and the lowest mean arterial pressure of the 3 outcome groups (p<0.01 for all). Biventricular and isolated left-ventricular congestion were common among patients who died or underwent HRT, respectively. Lactate, blood urea nitrogen, serum creatinine, and aspartate aminotransferase were highest in HF-CS patients experiencing in-hospital death. Intra-aortic balloon pump (IABP) was the most commonly used AMCS device in the overall cohort and among patients receiving HRT. Patients receiving more than one AMCS device had the highest in-hospital mortality rate irrespective of the number of vasoactive drugs used. Mortality decreased with deteriorating SCAI stages (stage B: 0%, stage C: 10.7%, stage D: 29.4%, stage E: 54.5%, 1-way ANOVA = <0.001). Conclusions : Patients with HF-CS experiencing in-hospital mortality had a high prevalence of biventricular congestion and markers of end-organ hypoperfusion. Substantial heterogeneity exists with use of AMCS in HF-CS with IABP being the most common device used and high rates of in-hospital mortality after exposure to more than one AMCS device.

Objective. To identify outcomes of patients undergoing emergency transcatheter aortic valve replacement (TAVR) and determine predictors of in-hospital mortality. Background. Emergency TAVR has emerged as a viable treatment strategy for patients with decompensated severe aortic stenosis and/or regurgitation; however, data on patients undergoing emergency TAVR are limited. Methods. All emergency TAVR procedures were identified from a single tertiary academic center between January 2015 and August 2018. Results. 31 patients underwent emergency TAVR due to cardiogenic shock (26 patients), electrical instability with incessant ventricular tachycardia (2 patients), severe refractory angina (2 patients), and decompensated heart failure with hypoxemic respiratory failure requiring mechanical ventilation (1 patient). Mechanical circulatory support (MCS) was used in 16 (51.6%). MCS initiation occurred immediately prior to TAVR in 10 patients and placed post-TAVR in 6 patients. 6 patients died before hospital discharge (in-hospital mortality 19.4%). 1-year and 2-year survival rates were 61.0% and 55.9%, respectively. Univariate predictors of in-hospital mortality were preprocedural pulmonary artery pulsatility index (PAPi) ≤1.8 (66.7% vs. 20.0%, p=0.01), intraprocedural cardiopulmonary resuscitation (CPR) (83.3% vs 4.0%, p≤0.001), acute kidney injury post-TAVR (80.0% vs. 4.2%, p≤0.001), initiation of dialysis post-TAVR (60.0% vs. 4.2%, p≤0.001), and MCS initiation post-TAVR (50.0% vs. 12.0%, p=0.03). MCS initiation before TAVR was associated with improved survival compared with post-TAVR initiation. Conclusion. Emergency TAVR in extreme risk patients with acute decompensated heart failure or cardiogenic shock secondary to severe aortic valve disease is associated with high in-hospital mortality rates. Careful patient selection taking into account right heart function, assessed by PAPi, and early utilization of MCS may improve survival following emergency TAVR.

Patients At Risk

Heart failure and cardiogenic shock are important causes of perioperative morbidity and mortality that require prompt recognition prior to the institution of specialized monitoring and treatment, including the consideration of circulatory assist devices. Patients at risk for perioperative heart failure require special consideration with respect to preoperative evaluation, medical optimization prior to proceeding with surgery, and monitoring throughout the perioperative period. The intraoperative and postoperative management need to be carefully planned in order to avoid the development of acute decompensated heart failure and cardiogenic shock. This chapter reviews the perioperative assessment and management of heart failure patients as well as the management of perioperative cardiogenic shock.

Introduction: Contemporary in-hospital mortality rates for patients presenting with acute myocardial infarction (AMI) and cardiogenic shock (CS) remain as high as 50%. The impact of comorbid lower extremity peripheral artery disease (LE-PAD) is unknown. Hypothesis: LE-PAD is associated with higher morbidity and mortality in patients presenting with CS and AMI. Methods: Medicare beneficiaries hospitalized with CS related to AMI from 10/2015-6/2017 were identified. PAD status was defined by the inpatient billing codes present in the year prior to presentation. Outcomes included in-hospital mortality, amputation, peripheral revascularization, and 6-month mortality. Adjusted regression models were used to evaluate outcomes. A subgroup analysis included patients requiring mechanical circulatory support (MCS). Results: Among 45,144 patients, 5.9% (N=2,651) had LE-PAD. The average age was 77.8±7.9, 59.8% were male and 83.0% were white. Cumulative in-hospital mortality was 46.8%, with greater risk among LE-PAD patients (55.2% vs 46.3%; adjusted OR 1.52, 95% CI 1.39-1.65). LE-PAD patients also had greater adjusted risk of in-hospital amputation (1.5% vs 0.2%; OR 3.23, 95% CI: 2.16-4.83), peripheral revascularization rates (1.4% vs 0.4%; OR 1.54, 95% CI: 1.06-2.23), and 6-month mortality (43.2% vs 23.7%; HR 2.06, 95% CI: 1.80-2.35). MCS was less frequently utilized in LE-PAD (20.1% vs. 38.1%, p<0.01). Adjusted in-hospital mortality, amputation and peripheral revascularization rates were comparable between LE-PAD and non-LE-PAD patients who received MCS. Non-MCS LE-PAD patients had a 2.28 fold higher adjusted 6-month mortality compared with MCS LE-PAD patients (95% CI 1.60-3.11; Figure). Conclusions: Comorbid PAD is associated with worse limb outcomes and mortality among patients with AMI and CS. Although MCS was less likely to be used in LE-PAD patients, in-hospital mortality and limb complication rates were comparable to non-LE-PAD MCS patients.

The Impact

Postoperative atrial fibrillation (PoAF) is a common complication in up to 40% of patients after cardiac surgery, increasing morbidity, hospital stay and costs. The myocardial substrate underlying PoAF is not fully characterized. The objective was to assess the impact of atrial fibrosis on incident AF and define the fibrosis threshold level predictive of PoAF. Methods: Right atrial appendages removed from patients undergoing elective CABG with no history of AF or class III/IV heart failure were used to characterize the ratio of collagen to myocardium (Masson’s trichrome; NIH ImageJ software; Fig A), which was correlated with incident AF. Percentage burden of fibrosis predictive of PoAF with high sensitivity and specificity was determined by ROC curve. Results: Of 28 patients (67±10 years, 64% males), 15 had PoAF. There were no age, gender or comorbidity differences between groups. Compared to the group that remained in sinus rhythm, patients with PoAF had a significantly higher ratio of extracellular collagen to myocardium (45±16% vs. 5±4%, p <0.001; Fig B). A threshold ratio of 12.7% collagen to myocardium (ROC area under the curve 0.997; z statistic 137; P<0.0001) with 96% sensitivity and 97% specificity identified those with PoAF (Fig C). A classification system based on histological extent of atrial fibrosis is proposed for identifying patients at risk for PoAF (Fig D). Conclusion: Ongoing studies will confirm the predictive value of this new classification system for identifying the atrial substrate predisposing PoAF and correlate with preoperative cardiac imaging and circulatory serum biomarkers to provide a novel noninvasive tool to stratify patients at risk for PoAF.

Introduction: There has been little focus on hospitalized acute decompensated heart failure (ADHF) that develops after admission, which may occur because of comorbid conditions, over-administration of fluid or post-surgical complications. Aims: To compare patient characteristics, case fatality, and hospital length of stay (LOS) associated with ADHF that develops after hospital admission as compared to those with ADHF at admission. Methods: Hospitalizations with possible ADHF were sampled, based on HF ICD codes, among those aged > 55 years from the four communities of the Atherosclerosis Risk in Communities Study (2005-2010). Medical records were abstracted with events classified by physician panel or computer classified. Case fatality was obtained through the National Death Index. We identified 4,503 (unweighted) events with definite/probable ADHF, after excluding those with unknown time of decompensation (n=81), hospital transfers (n=102), and race other than black or white (n=118). Demographic and clinical characteristics were compared by ADHF onset (at/after admission). Logistic regression was used to evaluate the association of ADHF onset with in-hospital mortality, and 28-days and one-year mortality, adjusted for demographics and comorbidity. Linear regression was used to evaluate the association of ADHF onset with log-transformed hospital LOS, adjusted for demographics. All analyses were weighted to account for the stratified sampling design. Results: Of 21,052 (weighted) ADHF events, 7.4% (n=1561) developed ADHF after admission. Patients with ADHF occurring after admission were older (mean: 79 vs. 75 years), and more likely white and female. Those with ADHF at admission were more likely to have a positive smoking history, COPD, and to be on dialysis. Presence of diabetes, hypertension and coronary artery disease were not significantly different between groups. In hospital mortality (16.5% vs. 6.3%; OR= 2.7, 95% CI=1.9-3.8) and 28-day mortality (23.9% vs. 10.1%; OR= 2.4, 95% CI=1.7-3.4) was higher among those who developed ADHF after admission. One-year case fatality was similar (39.4% vs. 33.6%; OR= 1.2, 95% CI=0.9-1.6). Unadjusted mean LOS was longer for those with ADHF occurring after admission (12.8 days, 95% CI=11.8-13.8) than those with ADHF at admission (7.2 days, 95% CI=6.8-7.6). The adjusted and geometric mean LOS was 1.3 days (95% CI=1.2-1.4) longer for those who developed ADHF after admission. Conclusion: Although patients with ADHF onset after admission were slightly older, differences in comorbidity do not indicate an easily identifiable subgroup for closer in-hospital monitoring. Development of ADHF after admission was associated with an alarmingly high early case fatality and longer hospital LOS compared to those with ADHF at hospital admission.
