Abstract
BACKGROUND Takotsubo syndrome (TTS) and its differentiation from anterior wall ST-elevation myocardial infarction on electrocardiography (ECG) has been a debate. METHODS Six studies comparing ECG changes in TTS and AW-STEMI were identified. The primary endpoint was reciprocal changes, presence of Q-waves, and QT-interval. An unadjusted odds ratio (OR) with a 95% confidence interval (CI) was calculated using Review Manager (RevMan) 5.3. RESULTS Six studies consisting of 1090 patients (TTS = 220, AW-STEMI = 870) were included. Reciprocal changes on ECG were less commonly associated with TTS than AW STEMI with OR of 0.05 and 95%CI- 0.02-0.11 (P-<0.00001). Q-wave presence on ECG was comparable between the groups with OR-0.68, 95%CI-0.08-5.63 (p-0.72). QT interval on ECG was comparable between the two groups with OR-1.09, 95%CI-0.63-1.54 (p-<0.00001). There was minimal publication bias among the studies. CONCLUSION AW STEMI is associated with reciprocal changes. Q-waves and QT interval has no differentiating significance between AW STEMI and TTS.

Abstract
OBJECTIVES This study addresses the incidence, trends, and impact of nosocomial infections (NI) on the outcomes of patients admitted with ST-segment elevation myocardial infarction (STEMI) and cardiogenic shock (STEMI-CS) using the United States National Inpatient Sample (NIS) database. METHODS We analyzed data from 105,184 STEMI-CS patients using the NIS database from the years 2005-2014. NI was defined as infections of more than or equal to three days, comprising of central line-associated bloodstream infection (CLABSI), urinary tract infection (UTI), hospital-acquired pneumonia (HAP), Clostridium difficile infection (CDI), bacteremia, and skin related infections. Outcomes of the impact of NI on STEMI-CS included in-hospital mortality, length of hospital stay (LOS) and costs. Significant associations of NI in patients admitted with STEMI-CS were also identified. RESULTS Overall, 19.1% (20,137) of patients admitted with STEMI-CS developed NI. Trends of NI have decreased from 2005-2014. The most common NI were UTI (9.2%), followed by HAP (6.8%), CLABSI (1.5%), bacteremia (1.5%), skin related infections (1.5%), and CDI (1.3%). The strongest association of developing a NI was increasing LOS (7-9 days; OR: 1.99; 95% CI: 1.75-2.26; >9 days; OR: 4.51; 95% CI: 4.04-5.04 compared to 4-6 days as reference). Increased mortality risk among patients with NI was significant, especially those with sepsis-associated NI compared to those without sepsis (OR: 2.95; 95% CI: 2.72-3.20). Patients with NI were found to be associated with significantly longer LOS and higher costs, irrespective of percutaneous mechanical circulatory support placement. CONCLUSIONS NI were common among patients with STEMI-CS. Those who developed NI were at a greater risk of in-hospital mortality, increased LOS and costs.

Abstract
Coronavirus Disease 2019 (COVID-19) is a rapidly progressing global pandemic that may present with a variety of cardiac manifestations including, but not limited to, myocardial injury, myocardial infarction, arrhythmias, heart failure, cardiomyopathy, shock, thromboembolism, and cardiac arrest. These cardiovascular effects are worse in patients who have pre-existing cardiac conditions such as coronary artery disease, hypertension, diabetes mellitus, and coagulation abnormalities. Other predisposing risk factors include advanced age, immunocompromised state, and underlying systemic inflammatory conditions. Here we review the cellular pathophysiology, clinical manifestations and treatment modalities of the cardiac manifestations seen in patients with COVID-19.

Abstract
Acute mechanical circulatory support (MCS) devices are widely used in cardiogenic shock (CS) despite a lack of high-quality clinical evidence to guide their use. Multiple devices exist across a spectrum from modest to complete support, and each is associated with unique risks. In this review, we summarize existing data on complications associated with the three most widely used acute MCS platforms: the intra-aortic balloon pump (IABP), Impella systems, and veno-arterial extracorporeal membrane oxygenation (VA-ECMO). We review evidence from available randomized trials and highlight challenges comparing complication rates from case series and comparative observational studies where a lack of granular data precludes appropriate matching of patients by CS severity. We further offer a series of best practices to help shock practitioners minimize the risk of MCS-associated complications and ensure the best possible outcomes for patients.

Abstract
BACKGROUND Bleeding complications and acute limb ischemia (ALI) are devastating vascular complications in patients with ST-segment elevation myocardial infarction (STEMI). Cardiogenic shock (CS) can further increase this risk due to multiorgan failure. In the contemporary era, percutaneous mechanical circulatory support is commonly used for management of CS. We hypothesized that vascular complications may be an important determinant of clinical outcomes for CS due to STEMI (CS-STEMI). OBJECTIVE We evaluated 10-year national trends, resource utilization and outcomes of bleeding complications, and ALI in CS-STEMI. METHODS We performed a retrospective cohort study of CS-STEMI patients from a large U.S. national database (National Inpatient Sample) between 2005 and 2014. Events were then divided into four different groups: no MCS, with intra-aortic balloon pump, percutaneous ventricular assist device includes Impella or Tandem Heart or extracorporeal membrane oxygenation. RESULTS Bleeding complications and ALI were observed in 31,389 (18.2%) and 1,628 (0.9%) out of 172,491 admissions with CS-STEMI, respectively. Between 2005 and 2014, overall trends increased for ALI; however, the number of bleeding events decreased. ALI was associated with increased in-hospital mortality in comparison to those without any ALI. However, bleeding complications were not associated with increased in-hospital mortality. Compared to patients without complications, both bleeding and ALI were associated with increased length of stay (LOS) and hospitalization costs. CONCLUSIONS Bleeding and ALI are common complications associated with CS-STEMI in the contemporary era. Both complications are associated with increased hospital costs and LOS. These findings highlight the need to develop algorithms focused on vascular safety in CS-STEMI.

Abstract
We assessed the trend of palliative care (PC) referrals and its effect on hospitalization cost and length of stay (LOS) in ruptured aortic aneurysm (rAA). The Nationwide Inpatient Sample from 2005 to 2014 was used to identify admissions with age ≥50 and rAA. A total of 54 134 rAA admissions were identified and 5019 (9.3%) had PC referrals. During the study period, PC referral rate increased from 0.97% to 15.3% ( P trend < .0001). Length of stay (1.7 vs 2.8 days, adjusted mean ratio [aMR] = 0.62, 95% confidence interval [CI]: 0.58-0.66), and cost (US$7778 vs US$13 575, aMR = 0.57, 95% CI: 0.52-0.63) were significantly lower in rAA admissions that did not undergo interventions. In the percutaneous repair group, LOS was similar but the cost was higher (US$61 759 vs US$52 260, aMR = 1.18, 95% CI: 1.05-1.30), whereas in surgical repair group, LOS was shorter (4.6 vs 5.9 days, aMR = 0.77, 95% CI: 0.73-0.82) but the cost was higher (US$59 755 vs US$52 523, aMR = 1.14, 95% CI: 1.02-1.28). Palliative care could shorten LOS and save hospitalization cost in rAA admissions not a candidate for repair. Further studies are required to investigate the variable effects of PC on rAA.

Abstract
To evaluate the impact of chronic thrombocytopenia (cTCP) on outcomes of transcatheter valvular procedures such as aortic valve implantation (TAVI), MitraClip, permanent pacemaker (PPM), implantable-cardioverter defibrillator (ICD), cardiac resynchronization therapy (CRT), left atrial appendage closure, and pericardiocentesis. Impact of cTCP on clinical outcomes following TAVI, Mitraclip, PPM, ICD, CRT, left atrial appendage closure, and pericardiocentesis procedures is not well described. Utilizing the National Inpatient Sample and (ICD-9-CM) procedural codes, we evaluated patients (age ≥18 years) who underwent these procedures, from January 1, 2009 to December 31, 2014, with or without cTCP as a chronic condition variable indicator. Propensity score matching model implemented to derive 2 matched groups. Propensity score matching created 47,292 and 47,351 hospitalizations matched pairs with and without cTCP, respectively. Patients with cTCP were older (mean age, 74.27 vs 72.26 years; absolute standardized differences [ASD] = 15.6) and less likely to be female (36.76% vs 43.74%, ASD = -14.31). They experienced higher in-hospital mortality (3.0% vs 2.0%; odds ratio [OR], 1.53; 95% confidence interval [CI], 1.27 to 1.83) and higher odds of vascular injury requiring surgery (2.63% vs 1.10%; OR, 2.43; 95% CI, 1.93 to 3.05). Postoperative hematoma and bleeding were 2-fold higher (4.57% vs 2.24%; OR, 2.08; 95% CI, 1.77 to 2.45) and 3-fold higher (6.34% vs 2.45%; OR, 2.69; 95% CI, 2.31 to 3.13) respectively among cTCP patients. They had greater health-care cost ($47,163 vs $35,763, p <0.0001) and longer hospital stay (mean 9.26 days vs 6.84 days, p <0.0001). In conclusion, cTCP patients had higher risk of complications after TAVI, MitraClip, PPM, ICD, CRT, left atrial appendage closure, and pericardiocentesis, including a 1.5-fold increased risk of in-hospital mortality.

Abstract
Background Patients with immune thrombocytopenic purpura (ITP) admitted with acute myocardial infarction (AMI) may be challenging to manage given their increased risk of bleeding complications. There is limited evidence in the literature guiding appropriate interventions in this population. The objective of this study is to determine the difference in clinical outcomes in AMI patients with and without ITP. Methods Using the United States national inpatient sample database, adults aged ≥18 years, who were hospitalized between 2007 and 2014 for AMI, were identified. Among those, patients with ITP were selected. A propensity‐matched cohort analysis was performed. The primary outcome was in‐hospital mortality. Secondary outcomes were coronary revascularization procedures, bleeding and cardiovascular complications, and length of stay (LOS). Results The propensity‐matched cohort included 851 ITP and 851 non‐ITP hospitalizations for AMI. There was no difference in mortality between ITP and non‐ITP patients with AMI (6% vs7.3%, OR:0.81; 95% CI:0.55‐1.19; P = .3). When compared to non‐ITP patients, ITP patients with AMI underwent fewer revascularization procedures (40.9% vs 45.9%, OR:0.81; 95% CI:0.67‐0.98; P = .03), but had a higher use of bare metal stents (15.4% vs 11.3%, OR:1.43; 95% CI:1.08‐1.90; P = .01), increased risk of bleeding complications (OR:1.80; CI:1.36‐2.38; P < .0001) and increased length of hospital stay (6.14 vs 5.4 days; mean ratio: 1.14; CI:1.05‐1.23; P = .002). More cardiovascular complications were observed in patients requiring transfusions. Conclusions Patients with ITP admitted for AMI had a similar in‐hospital mortality risk, but a significantly higher risk of bleeding complications and a longer LOS compared to those without ITP. Further studies are needed to assess optimal management strategies of AMI that minimize complications while improving outcomes in this population.

Abstract
Abstract
Background
There is scarce evidence reflecting the clinical outcomes in patients with Idiopathic Thrombocytopenic Purpura (ITP) and Acute Myocardial Infarction (AMI). The ITP patient population is at higher risk of bleeding complications due to low platelet counts and difficulty in managing their antiplatelet and anticoagulation therapy. In our study, we sought to assess clinical outcomes of ITP patients admitted with AMI using the US national inpatient sample (NIS) database.
Purpose
To determine difference in in-hospital mortality, clinical complications, and length of stay (LOS) in AMI patients with and without ITP.
Methods
We identified adults aged ≥18 years hospitalized from 2005 to 2014 with AMI as their primary diagnosis utilizing ICD-9 codes 410.0 to 410.92. Patients with ITP were identified using ICD-9 code 287.31. The primary outcome was in-hospital mortality. Secondary outcomes included coronary revascularization procedures (PCI and CABG), and in-hospital complications including bleeding (intracranial, epistaxis, GI, and GU bleeding, hematoma, and bleeding requiring transfusion), cardiac complications, transfusions, acute ischemic stroke (AIS), and LOS. A propensity-matched cohort accounting for demographic characteristics, comorbidities, and cardiovascular risk factors, was created to compare these outcomes. Patients with secondary causes of ITP such as HIV, pregnancy, sepsis, SLE, malignancy were excluded.
Results
A total of 1108034 AMI admissions, of which 1002 with ITP, were identified. In the unmatched group, patients with ITP were older, and had more comorbidities (diabetes mellitus; hypothyroidism; atrial fibrillation; previous history of cardiovascular, peripheral, and end stage renal disease; all p<0.05). In the AMI population, 851 ITP and 851 non-ITP admissions were propensity-matched. Figure 1 illustrates the primary and secondary outcomes of the study among the propensity-matched study groups. Although there was no difference in short-term mortality between the ITP and non-ITP patients with AMI, patients with ITP were less likely to undergo coronary revascularization possibly because of thrombocytopenia. Patients with ITP had significantly more bleeding complications and transfusions. We observed in our study that patients with ITP had a significantly longer LOS compared to non-ITP patients (6.1 vs 5.4 days, with a mean ratio of 1.14 (95% CI: 1.05,1.23)).
Conclusion
In the large population of patients included in the NIS database, patients with ITP admitted with AMI, have a significantly higher rate of bleeding complications, undergo less PCI and have a longer LOS compared to AMI patients without ITP. There are no current guidelines by ACC/AHA/ESC regarding management of patients with AMI and thrombocytopenia. These results warrant further investigation through randomized controlled trials including patients with thrombocytopenia to assess long term outcomes and to define optimal management in this population.

Abstract
Transcatheter aortic valve implantation (TAVI) has been used to treat high surgical risk cohorts but has been expanded to treat low-to-intermediate risk cohort as well. We performed a systematic review and meta-analysis to compare the outcomes between TAVI and surgical aortic valve replacement (SAVR) in low-to-intermediate risk cohort. We queried PUBMED, EMBASE, and ClinicalTrial.gov for relevant articles. Randomized controlled trials that compared at least one of the outcomes of interest between TAVI and SAVR were included. Risk ratio (RR) and 95% confidence interval (CI) were pooled with a random-effects model to compare the risk of the primary outcome between the 2 procedures. The primary outcome was a composite of all-cause mortality or disabling/major stroke at 1 year. Seven studies with a total of 7,143 patients (3,665 TAVI) were included. All-cause mortality or disabling/major stroke at 30 days (6 studies, RR 0.71, 95% CI 0.49 to 1.03) was similar between TAVI and SAVR but was significantly lower in TAVI at 1 year (5 studies, RR 0.81, 95% CI 0.67 to 0.98). All-cause mortality was similar at both 30 days (7 studies, RR 0.90, 95% CI 0.67 to 1.21) and 1 year (6 studies, RR 0.89, 95% CI 0.76 to 1.04). Disabling/major stroke was similar between the 2 procedures (6 studies, RR 0.69, 95% CI 0.42 to 1.12) at 30 days but was significantly lower in TAVI at 1 year (5 studies RR 0.71, 95% CI 0.51 to 0.98). Age, gender, diabetes, and surgical risk score did not modulate the primary outcome. TAVI had a significantly lower composite of all-cause mortality or disabling/major stroke at 1 year compared with SAVR in low-to-intermediate surgical risk cohort.

Abstract
Background:
Ventricular septal defect (VSD) is a lethal complication of acute myocardial infarction (AMI) and is often associated with cardiogenic shock. The optimal form of percutaneous mechanical circulatory support (MCS) for AMI-VSD is unknown.
Methods and Results:
We used a previously validated cardiovascular model to simulate AMI-VSD with parameters adjusted to replicate average hemodynamics reported in the literature, including a pulmonary-to-systemic blood flow ratio of 3.0. We then predicted effects of different types of percutaneous MCS (including intra-aortic balloon pumping, Impella, TandemHeart, and extracorporeal membrane oxygenation) on pressures and flows throughout the cardiovascular system. The simulation replicated all major hemodynamic parameters reported in the literature with AMI-VSD. Inotropes and vasopressors worsened left-to-right shunting, whereas vasodilators decreased shunting at the expense of worsening hypotension. All MCS devices increased forward blood flow and arterial pressure but other effects varied among devices. Impella 5.0 provided the greatest degree of pulmonary capillary wedge pressure reductions and decreased left-to-right shunting. Extracorporeal membrane oxygenation worsened pulmonary capillary wedge pressure and shunting, which could be improved by adding Impella or passive left ventricular vent. Pulmonary-to-systemic blood flow ratio could not be reduced below 2.0, and pulmonary flows remained high with all forms of MCS.
Conclusions:
Although no form of percutaneous MCS normalized hemodynamics in AMI-VSD, pulmonary capillary wedge pressure and shunting were worsened by extracorporeal membrane oxygenation and improved by Impella. Accordingly, based on hemodynamics alone, Impella provides the optimal form of support in AMI-VSD. However, other factors, including team experience, device availability, potential for tissue ingestion, and clinical characteristics, need to be considered when choosing a percutaneous MCS device for AMI-VSD.

Abstract
BACKGROUND Myocarditis may be associated with hemodynamic instability and portends a poor prognosis when associated with cardiogenic shock (CS). There are limited data available on the incidence of in-hospital mortality, CS, and utilization of mechanical circulatory support (MCS) devices in these patients. METHODS We queried the 2005-2014 National Inpatient Sample databases to identify all patients aged >18 years with myocarditis in the United States. RESULTS The number of reported cases of myocarditis per 1 million gradually increased from 95 in 2005 to 144 in 2014 (Pfor trend <.01). The trend and incidence of endomyocardial biopsy remained the same despite the increase in clinical diagnosis. Overall, in-hospital mortality was 4.43% of total admissions without a change in overall trend over the study period. We also observed a significant increase in the incidence of CS from 6.94% in 2005 to 11.99% in 2014 (Pfor trend <.01). There was a parallel increase in the utilization of advanced MCS devices during the same time period such as extracorporeal membrane oxygenation or percutaneous cardiopulmonary support (0.32% in 2005 to 2.1% in 2014; P< .01) and percutaneous ventricular assist devices such as Impella/tandem heart (0.176% in 2005 to 1.75% in 2014; P< .01). CONCLUSION Although the incidence of myocarditis has increased in the last decade, the in-hospital mortality has remained the same despite increases in the incidence of CS, possibly reflecting the benefits of increased usage of advanced MCS devices. We noted that increasing age, presence of multiple comorbidities and CS were associated with an increase in in-patient mortality.
