Platypnea-Orthodeoxia Syndrome: Positional Reversal of the Interatrial Pressure Gradient Demonstrated by Atrial Septal Motion

Serio Farris and Serio M Kerala
Abstract

Platypnea-Orthodeoxia Syndrome (POS) is a rare clinical syndrome characterized by dyspnea and hypoxemia while upright that are relieved when the patient is supine. A right to left shunt in combination with several hypothesized hemodynamic or structural factors are needed to develop the syndrome. It is an important source of dyspnea in a small percentage of often-elderly patients. The exact mechanism for the positional increase in the shunt has remained elusive.

Adenosine Stress Myocardial Perfusion Scintigraphy and Echocardiography Application with Same Infusion

Zehra Pinar Koc, Necati Dagli, Tansel Ansal Balci, Ilgin Karaca, Ferat Kepenek and Tolga Cakmak
Abstract

Stress Echo was performed by an experienced cardiologist and MPS results were interpreted by an experienced nuclear medicine physician who didn't know stress Echo results according to 17 segment models. Sixteen patients underwent coronary angiography. Ischemia territory size in both the adenosine stress Echo and MPS were recorded and compared in segment and in patient basis.

A Case of Coronary Artery Spasm Associated with Lisdexamfetamine Use

Harmony R Reynolds and Leon H Charney
Abstract

Coronary artery spasm is a cause of myocardial infarction with non-obstructive coronary arteries (MINOCA). Coronary spasm may occur spontaneously or in response to prescribed or illicit drugs. Myocardial injury and cardiomyopathies have been reported in association with the use of stimulants in children and adults with attention deficit hyperactivity disorder (ADHD).

Improving Atherosclerotic Cardiovascular Risk Documentation and Consequent Preventive Management in the Electronic Medical Records of Diabetic Patients

Muna aseel, Amal Al-Ali, Zelaikha Alwahedi and Mohamed Salem
Abstract

Proper documentation of Atherosclerotic Cardiovascular Disease (ASCVD) risk score and its consequent management in the newly applied electronic medical records (EMR) for diabetic's patients attending non-communicable diseases clinic in West Bay Health Center is less than ideal during Jan 2015 and Feb 2015. Poor documentation of ASCVD risk score and its consequent management will result in improper management for type 2 diabetic patients, and it will lead to undesirable consequences.

Effect of Exercise Training on Heart Sympathetic Activity and Lung Function in Mexican obese Adolescents

Benigno Linares-Segovia, Estela Nunez Lemus, Manuel Lara Marquez, Rogelio Torres Guzman, Juan Manuel Guizar-Mendoza and Norma Amador-Licona
Abstract

Introduction: The aim of this study was to evaluate the short term effect of a moderate-intensity physical activity program on heart sympathetic activity and lung function in Mexican obese adolescents. Materials and methods: We performed a longitudinal study in 38 healthy obese adolescents (24 female and 14 male). Subjects were submitted to aerobic exercise training during 90 minutes for 16 weeks, 5 days per week. Before and after the intervention program, blood pressure, anthropometric measurements, glucose, insulin, and leptin levels were evaluated, spirometry and 60 minutes electrocardiograph monitoring were performed.

Temporal Trends in Insertion of Implantable Cardioverter Defibrillators from an Australian Regional Tertiary Centre's Perspective

Harsh V Thakkar and John V Amerena
Abstract

Implantable Cardioverter Defibrillator (ICD) therapy is now standard therapy for prevention of Sudden Cardiac Death (SCD) in high-risk patients. In 2006, the Medical Services Advisory Committee (MSAC) reviewed the role of ICDs and approved them to be used for both primary and secondary prevention. This study reviews the temporal trends in indications for insertion of ICD at Geelong Cardiology Practice (GCP).

Radial-Linear Ablation in Peri-pulmonary Vein Area Prevents Inducible Atrial Fibrillation in Dogs

Xue Zhao, Yinxiang Zhu, Xiang Mei, Jiayou Zhang, Jianqiang Hu, Wenliang Lu, Xingui Guo, Li Dai, Kailei Shi and Zhenguo Liu
Abstract

A total of 22 dogs of both sexes (5-7 years old) were divided into two groups: 10 in control and 12 in ablation group. Multiple radial-linear lesions were created from PV orifice to peri-PV area in the dogs with CARTO guidance. The control animals went through the same procedure except ablation. AF inducibility was evaluated before and immediately after the procedure. All animals had inducible AF (100%) by atrial pacing combined with or without isoproterenol at baseline.
