Background: The role of body composition as a risk factor for adverse outcomesduring coronary artery bypass surgery (CABG) has been controversial. The goal of this study was to evaluate the effect of body weight on mortality in patients undergoing CABG.

Method: Using a large NIS database and ICD-10 coding for different bodyweight categories, we evaluated the effect of cachexia, overweight, obesity, and morbid obesity on in-hospital mortality after CABG.

Background: Breast implants interfere with myocardial perfusion imaging (SPECT) and echocardiographic windows leading to increased false positive results. To validate this concept, we hypothesized that patients with breast implants should have higher positive cardiac testing and coronary angiogram with lower percutaneous coronary intervention (PCI) rates compared to women without a breast implant.

Methods: Using ICD 10 codes for breast implants, abnormal results of cardiac functional study, coronary angiogram, and percutaneous coronary interventions, we evaluated any association between these parameters in adult women with breast implants utilizing the National Inpatient Sample (NIS) database.

Article Synopsis
  • * ACCS may not respond well to typical treatments like inotropes and fluids, making glucocorticoid administration crucial for survival, which emphasizes the importance of early detection of AI.
  • * The study reviews case reports linking acute cardiomyopathies to AI and discusses possible mechanisms, urging physicians to consider AI as a possible cause in critically ill patients with cardiogenic shock.

The obesity paradox has been observed in patients with cardiovascular disease. The goal of this study was to evaluate whether obesity has a protective effect in patients presenting with an ST elevation myocardial infarction (STEMI). Using the large Nationwide Inpatient (NIS) sample database, we evaluated the mortality in patients with a STEMI based on weight categories.

Introduction: The left atrium (LA) size can change due to cardiac pathologies like heart failure and aging. While the link between LA enlargement and left ventricular (LV) dysfunction is acknowledged, this study aims to assess the negative predictive value of normal LA size concerning the severity of LV systolic function in a large cohort undergoing diagnostic echocardiography.

Methods: This retrospective cohort study, conducted at the University of California, Irvine Medical Center from 1984 to 1998, aimed to elucidate the negative predictive value of normal LA size measured by M-mode and two-dimensional echocardiography in a large cohort undergoing diagnostic assessment.

Depression has been suggested to increase the risk of cardiovascular disease, but many studies assessed depression after heart disease onset. This study evaluated the association between depression and myocardial infarction (MI) using a large inpatient database. We analyzed patients from the National Inpatient Sample hospitals from 2005 to 2020, selecting those aged >30 with ICD-9 and ICD-10 codes for segment elevation (ST) elevation myocardial infarction (STEMI), non-ST elevation myocardial elevation (NSTEMI) and major depression.

Background: Advanced chronic kidney disease (ACKD) is common in patients undergoing percutaneous coronary intervention (PCI). Post-PCI bleeding has been shown to increase mortality and remains an important challenge in these patients. Previous studies have shown increased post-PCI bleeding in CKD patients but often ACKD patients are excluded from these trials.

Background: PTSD leads to increased levels of stress hormones and dysregulation of the autonomic nervous system which may trigger cardiac events. The goal of this study is to evaluate any association between PTSD and the occurrence of STEMI and NSTEMI using a large database.

Method: Using the Nationwide Inpatient Sample (NIS) and ICD-9 codes from 2005 to 2014 (n=1,621,382), we performed a univariate chi-square analysis of in-hospital occurrence of STEMI and NSTEMI in patients greater than 40 years of age with and without PTSD.

Background: Percutaneous coronary intervention (PCI) in patients with bifurcation lesions is associated with higher complexity and adverse outcomes. The goal of this study was to evaluate the inpatient outcomes of patients with PCI of bifurcation lesions.

Methods: The National Inpatient Sample (NIS) database, years 2016-2020, was studied using ICD 10 codes.

Introduction: Coronary perforation is one of the major complications of percutaneous coronary intervention (PCI). The goal of this study was to evaluate adverse outcomes and mortality in patients suffering from coronary perforation during PCI above the age of 30.

Methods: The National Inpatient Sample (NIS) database, years 2016-2020, was studied using ICD 10 codes.

The goal of this study was to evaluate the effect of extracorporeal membrane oxygenation (ECMO) on mortality in patients with cardiogenic shock excluding Impella and IABP use. The large Nationwide Inpatient Sample (NIS) database was utilized to study any association between the use of ECMO in adults over the age of 18 and mortality and complications with a diagnosis of cardiogenic shocks. ICD-10 codes for ECMO and cardiogenic shock for the available years 2016-2020 were utilized.

Background: Breast implants interfere may interfere with surface ECG recording. The goal of this study was to evaluate if the presence of breast implants can lead to abnormal electrocardiogram (ECG) using a large database in adults.

Methods: Using ICD 10 codes for breast implants and abnormal ECG, we evaluated any association between abnormal ECG coding in adult women with breast implants compared to women without breast implants utilizing the National Inpatient Sample (NIS) database.

Background: Advanced chronic kidney disease (ACKD) is common in patients undergoing percutaneous coronary intervention (PCI) and is associated with adverse outcomes. These patients are often excluded from revascularization studies. The goal of this study was to evaluate the impact of ACKD in patients undergoing PCI.

Colchicine is one of the established drugs of choice for post-myocardial infarction (MI) induced pericarditis, given its anti-inflammatory properties. Recently, colchicine received FDA approval for secondary prevention of atherosclerotic cardiovascular disease, which leads to concerns regarding its anti-healing effects on myocardial tissue post-infarction. We present a case of a suspected colchicine-induced myocardial rupture in an elderly male, who presented with a syncopal episode while on colchicine three weeks after the late presentation of infero-posterior ST-elevation myocardial infarction.

Background: The prevalence of hypertrophic cardiomyopathy (HCM) can be silent and can present with sudden death as the first manifestation of this disease. The goal of this study was to evaluate any association between reported physical symptoms with the presence of suspected HCM.

Method: The Anthony Bates Foundation has been performing screening echocardiography across the United States for prevention of sudden death since 2001.

Impella and intra-aortic balloon pumps (IABP) are commonly utilized in patients with cardiogenic shock. However, the effect on mortality remains controversial. The goal of this study was to evaluate the effect of Impella and IABP on mortality in patients with cardiogenic shock the large Nationwide Inpatient Sample (NIS) database was utilized to study any association between the use of IABP or Impella on outcome.

Background: Aortic regurgitation (AR) is associated with increasing age, rheumatic heart disease, and a bicuspid aortic valve, but its association with other comorbidities and race is less known. The purpose of this study was to investigate any association between AR and comorbid conditions in older adults above 40.

Method: The large Nationwide Inpatient Sample database was utilized for our study using uni- and multivariate analysis.

Atrial septal abnormalities are common congenital lesions that remain asymptomatic in many patients until adulthood. Adults with atrial septal defects (ASD) most commonly have ostium secundum ASD. Transcatheter closure has become increasingly popular in recent years as a successful alternative method to surgery for treating ASD and patent foramen ovale (PFO).

Background: Patients with hypertrophic cardiomyopathy (HCM) usually have abnormal electrocardiograms consistent with left ventricular hypertrophy (LVH). The goal of this study was to evaluate the prevalence of abnormal ECG findings (LVH, T wave inversion, left bundle branch block, and left atrial enlargement) in participants with suspected HCM detected during screening echocardiography.

Method: The Anthony Bates Foundation has been performing screening echocardiography across the United States for the prevention of sudden death since 2001.
