Interplanetary shocks lacking type II radio bursts [PDF]

Astrophys.J.710:1111-1126,2010, 2009
We report on the radio-emission characteristics of 222 interplanetary (IP) shocks. A surprisingly large fraction of the IP shocks (~34%) is radio quiet (i.e., the shocks lacked type II radio bursts). The CMEs associated with the RQ shocks are generally slow (average speed ~535 km/s) and only ~40% of the CMEs were halos.

Dual Antiplatelet Therapy Prior to Percutaneous Coronary Intervention for Acute Coronary Syndrome: Prevalence and Outcomes in Contemporary Practice

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Dual antiplatelet therapy (DAPT) is standard following percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). Preloading is the practice of administering both aspirin and a P2Y12 inhibitor before PCI. DAPT preloading is common practice, however clinical trial evidence demonstrating benefit is lacking.

Mechanical circulatory support in cardiogenic shock

Journal of Intensive Care, 2023
Cardiogenic shock is a complex and diverse pathological condition characterized by reduced myocardial contractility. The goal of treatment of cardiogenic shock is to improve abnormal hemodynamics and maintain adequate tissue perfusion in organs.

Safety and Efficacy of a Plug‐Based Vascular Closure Device After Percutaneous Microaxial Flow Pump in the Treatment of Complex and High‐Risk Indicated Patients

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Femoral large‐bore vascular access is an important and constantly increasing technique in interventional treatment. Temporary circulatory support in complex and high‐risk indicated patients (CHIP) presents a challenge in terms of postinterventional access site closure.

Pediatric cardiogenic shock: Current perspectives

Archives of Medicine and Health Sciences, 2015
Cardiogenic shock is a pathophysiologic state where an abnormality of cardiac function is responsible for the failure of the cardiovascular system to meet the metabolic needs of the body tissues.Though it is less common than hypovolemia as the primary ...

Recycling cardiogenic artifacts in impedance pneumography [PDF]

arXiv, 2018
Purpose: Biomedical sensors often exhibit cardiogenic artifacts which, while distorting the signal of interest, carry useful hemodynamic information. We propose an algorithm to remove and extract hemodynamic information from these cardiogenic artifacts.

Shock Waves and Energy Dissipation in Magnetohydrodynamic Turbulence [PDF]

, 2018
Shock waves play an important role in turbulent astrophysical media by compressing the gas and dissipating the turbulent energy into the thermal energy. We here study shocks in magnetohydrodynamic turbulence using high-resolution simulations. Turbulent Mach numbers of $\mathcal{M}_\text{turb}=0.5-7$ and initial magnetic fields of plasma beta $\beta_0=0.

Hypocalcemic cardiomyopathy presenting as cardiogenic shock

Annals of Pediatric Cardiology, 2011
Hypocalcemia is a less known but treatable cause for dilated cardiomyopathy, leading to severe heart failure in children. Cardiogenic shock related to hypocalcemic cardiomyopathy is a rare event.

Six years of continuous mechanical circulatory support following chronic graft failure

Artificial Organs, Volume 47, Issue 1, Page 214-216, January 2023., 2023
Re‐transplantation is the preferred treatment for patients with chronic heart transplant failure. If re‐transplantation is not a viable option due to the patient's comorbidities, left ventricle assist device can be used as the destination treatment. An interdisciplinary approach with thorough follow‐up can help in the early detection and treatment of ...

Spontaneous Coronary Artery Dissection with Cardiogenic Shock in the United States

Reviews in Cardiovascular Medicine
Background: Spontaneous coronary artery dissection (SCAD) is defined as a non-traumatic separation of the epicardial coronary artery walls that creates a false lumen.
