The Effect Of Mock Code Blue Simulations And Dedicated Advanced Cardiac Life Support Didactics On Resident Perceived Competency., Dallis Q Ngo, Christina Vu, Thien Nguyen, Patricia Sotolongo, Manika Talati, Nikki Zahabi, Katrina Platt

Articles, Abstracts, and Reports

In-hospital cardiac or pulmonary arrest is associated with high mortality. In the USA, approximately 200,000 of these events occur and are associated with overall survival rates of 18%-20%. Despite advances in resuscitative methods, the probability of intact survival also remains unfavorable. Though many factors play a role, we believe a large portion of a patient's survival is dependent on the competency of the leader of the code blue or resuscitative team's efforts. Newly minted physicians who enter medical training in their respective residencies are equipped with a wide range of clinical competency in regards to hands-on experience and aptitude with …

Progress In The Seasonal Variations Of Blood Lipids: A Mini-Review., Xiaochun Ma, Haichen Yan, Haizhou Zhang, Mansen Wang, Qunye Zhang, Xiaoming Zhou

Articles, Abstracts, and Reports

The seasonal variations of blood lipids have recently gained increasing interest in this field of lipid metabolism. Elucidating the seasonal patterns of blood lipids is particularly helpful for the prevention and treatment of cardiovascular and cerebrovascular diseases. However, the previous results remain controversial and the underlying mechanisms are still unclear. This mini-review is focused on summarizing the literature relevant to the seasonal variability of blood lipid parameters, as well as on discussing its significance in clinical diagnoses and management decisions.

Abstract 219: Use Of Machine Learning Models To Identify Atherosclerotic Cardiovascular Disease Patients At Very High Risk For Future Events In A Multi-State Health Care System, Hsin-Fang Li, Amir Ali, Kateri Spinelli, A Sajja, Ss Virani, Ss Martin, Tyler J Gluckman

Articles, Abstracts, and Reports

Background: In the 2018 AHA/ACC Blood Cholesterol Guideline, it is recommended that ASCVD patients be classified as very high-risk (VHR) vs not-VHR (NVHR) to guide treatment decisions. This has important implications for ezetimibe and PCSK9 inhibitor eligibility. We aimed to develop a tool that could assist in more easily identifying VHR patients based on machine learning (ML) techniques. This approach offers a powerful, assumption-free alternative to conventional methods, such as logistic regression, to identify potential interactions among risk factors while incorporating the hierarchy of interaction among variables.

Method: We used EHR-derived ICD-10 codes to identify patients within our health system …

Articles, Abstracts, and Reports

Background

Despite guidelines supporting FFR/iFR to guide PCI, these modalities remain underutilized. We sought to characterize factors associated with FFR/iFR use in patients undergoing index PCI for an acute coronary syndrome (ACS) or stable ischemic heart disease (SIHD).

Methods

ICD-9/10 codes were used to identify patients undergoing PCI and receiving FFR/iFR for an ACS (n=1,042,896) or SIHD (n=255,213) in a Medicare claims database from Jan. 1, 2013-June 30, 2018. Patients with functional/anatomical testing were excluded (5d prior in ACS; 60d prior in SIHD). Individuals with FFR/iFR performed 1-60 days prior to PCI were also excluded to limit analysis to non-staged …

Clinical Characteristics Of Patients Classified As Very High Risk And Not Very High Risk Based On The 2018 Aha/Acc Multi-Society Cholesterol Guideline, Aparna Sajja, Amir Ali, Hsin-Fang Li, Kateri Spinelli, Salim S. Virani, Seth Shay Martin, Tyler J Gluckman

Articles, Abstracts, and Reports

Background

The 2018 AHA/ACC Cholesterol Guideline recommendation to classify ASCVD patients as very high-risk (VHR) vs not-VHR (NVHR) has important implications for ezetimibe and PCSK9 inhibitor eligibility. We aimed to define the clinical characteristics of these two groups within a large multi-state healthcare system in the Western U.S.

Methods

We performed a retrospective cohort analysis of patients defined as having ASCVD in 2018 using EHR ICD-10 codes. VHR was defined by ≥2 major ASCVD events (ACS ≤12 months, history of MI >12 months, ischemic stroke, or symptomatic PAD) or 1 major ASCVD event and ≥2 high-risk conditions (age ≥65, DM, …

Comparison Of Echocardiographic Outcomes Following Transcatheter Aortic Valve Replacement With Edwards S3 23 Mm Versus Medtronic Evolut 26 Mm Valves, Michael Ring, Ruyun Jin, Rollie Parrish, Brydan Curtis, Matthew Forrester, Branden Reynolds, Sameer Gafoor

Articles, Abstracts, and Reports

Background

Patients with small aortic valve annulus (SAVA) undergoing TAVR are prone to higher post TAVR trans-valve gradients. In many such patients, the choice of TAVR valve commonly involves choosing between the Edwards S3 23 mm (ES23) versus the Medtronic Evolut 26 mm (ME26). The supraannular design of the Evolut has been touted as providing superior hemodynamics in SAVA. We sought to compare performance of these two valves in SAVA, particularly in regard to occurrence of elevated trans-valve gradients.

Methods

We queried the Providence St Joseph Health STS/ACC TVT Registry database for patients undergoing TAVR for SAVA with either the …

Implementation Of A Cardiogenic Shock Protocol And Data Review Process Is Associated With Improved In-Hospital Survival, Adrienne Jones, Renee Swanson, Kateri Spinelli, Joshua Remick, Daniel Westerdahl, Jill M Gelow, David Hotchkin, Jason Wells, Tim Lewis, Robert Kim, Jeff Robinson, Roxanna Barr, Sarah Ramelli, Jacob Abraham

Articles, Abstracts, and Reports

Background: Despite increasing use of mechanical circulatory support devices (MCS), cardiogenic shock (CS) mortality is persistently high, with worsening outcomes in later stages of CS. Delays in diagnosis and practice variation may contribute to in-hospital mortality.

Methods: In June 2018, we devised and implemented a CS protocol at two hospitals from one health system in Portland, OR. The CS protocol was designed to promote early CS recognition, rapid notification of a multi-disciplinary specialty team lead by a heart failure cardiologist, invasive hemodynamic evaluation, and institution of MCS as appropriate. CS was defined by widely accepted clinical and hemodynamic criteria. Patient …

A Case Of Blunt Trauma-Induced St-Elevation Myocardial Infarction Sustained During A Prison Brawl., Zachary T Clark, Natalie Thiel, John Perry, Michael R Minckler

Articles, Abstracts, and Reports

Myocardial infarction (MI) is a serious and time-sensitive condition. MIs are typically seen in patients with coronary artery disease (CAD) and are caused by the rupture of an atherosclerotic plaque due to factors contributing to plaque instability. However, this case illustrates that plaque rupture can also be caused by blunt trauma to the chest. Considering MI as a possible result of chest trauma may decrease time from presentation to diagnosis and treatment and, therefore, improve outcomes in similar cases, particularly when patients presents unusually or with very few risk factors for MI.

Articles, Abstracts, and Reports

BACKGROUND: Advancement in the surgical techniques should translate into better outcome. The goal of this study was to evaluate mortality trends from aortic valve surgery in the United State using large inpatient database.

METHOD: The Nationwide Inpatient Sample (NIS) database was used to calculate the age-adjusted mortality rate from aortic valve surgery from 1988 to 2011 in the United State using ICD-9 coding for aortic valve surgery.

RESULTS: We found that age adjusted mortality rate from aortic valve surgery gradually decreased from 1988 until end of study in 2011 to the lowest level with elimination of gender gap that was …

Investigating The Effects Of Brainstem Neuronal Adaptation On Cardiovascular Homeostasis., James H Park, Jonathan Gorky, Babatunde Ogunnaike, Rajanikanth Vadigepalli, James S Schwaber

Articles, Abstracts, and Reports

Central coordination of cardiovascular function is accomplished, in part, by the baroreceptor reflex, a multi-input multi-output physiological control system that regulates the activity of the parasympathetic and sympathetic nervous systems via interactions among multiple brainstem nuclei. Recent single-cell analyses within the brain revealed that individual neurons within and across brain nuclei exhibit distinct transcriptional states contributing to neuronal function. Such transcriptional heterogeneity complicates the task of understanding how neurons within and across brain nuclei organize and function to process multiple inputs and coordinate cardiovascular functions within the larger context of the baroreceptor reflex. However, prior analysis of brainstem neurons revealed …
