Recurrent Acute Myocardial Infarction In Patients With Immune Thrombocytopenic Purpura, Fengyi Shen, Tonga Nfor, Tanvir Bajwa

Journal of Patient-Centered Research and Reviews

Immune thrombocytopenic purpura (ITP), also known as idiopathic thrombocytopenic purpura, is an acquired immune-mediated disease of adults and children characterized by a transient or persistent decrease of platelets and, depending upon the degree of thrombocytopenia, an increased risk of bleeding. The use of standard treatments for acute myocardial infarction (AMI), such as antiplatelet agents and anticoagulants, pose serious problems in patients with ITP due to the potential higher risk of bleeding complications. There are no current guidelines available for management of ITP patients with AMI. In this brief review of the limited available literature, we discuss the proposed pathophysiological link …

Integrated Guidance On The Care Of Familial Hypercholesterolaemia From The International Fh Foundation., Gerald F Watts, Samuel Gidding, Anthony S Wierzbicki, Peter P Toth, Rodrigo Alonso, W Virgil Brown, Eric Bruckert, Joep Defesche, Khoo Kah Lin, Michael Livingston, Pedro Mata, Klaus G Parhofer, Frederick J Raal, Raul D Santos, Eric J G Sijbrands, William G Simpson, David R Sullivan, Andrey V Susekov, Brian Tomlinson, Albert Wiegman, Shizuya Yamashita, John J P Kastelein

Familial hypercholesterolaemia (FH) is a dominantly inherited disorder present from birth that markedly elevates plasma low-density lipoprotein (LDL) cholesterol and causes premature coronary heart disease. There are at least 20million people with FH worldwide, but the majority remain undetected and current treatment is often suboptimal. To address this major gap in coronary prevention we present, from an international perspective, consensus-based guidance on the care of FH. The guidance was generated from seminars and workshops held at an international symposium. The recommendations focus on the detection, diagnosis, assessment and management of FH in adults and children, and set guidelines for clinical …

Addressing The Controversy Of Rate-Versus-Rhythm Control In Atrial Fibrillation, Tahmeed Contractor, Vadim Levin, Ravi Desai, Francis E Marchlinski

Vadim A Levin MD

Atrial fibrillation is the most common sustained cardiac arrhythmia and significantly increases patient risk of stroke, cardiomyopathy, and mortality. Rate versus rhythm control as the "best" treatment strategy remains an issue of considerable, ongoing debate. A multitude of clinical trials have compared the 2 strategies and have not shown any benefit of one approach over the other. However, the trials were conducted in specific subgroups of patients and demonstrated low success rates with antiarrhythmic drug (AAD) therapy and a high incidence of adverse AAD effects. Sub-analyses of the trials have confirmed that successful rhythm control with sinus rhythm restoration is …

Induction Of Autophagy Restores The Loss Of Sevoflurane Cardiac Preconditioning Seen With Prolonged Ischemic Insult., Mayumi Shiomi, Masami Miyamae, Genzou Takemura, Kazuhiro Kaneda, Yoshitaka Inamura, Anna Onishi, Shizuka Koshinuma, Yoshihiro Momota, Toshiaki Minami, Vincent M. Figueredo, M.D.

Sevoflurane preconditioning against myocardial ischemia-reperfusion injury is lost if the ischemic insult is too long. Emerging evidence suggests that induction of autophagy may also confer cardioprotection against ischemia-reperfusion injury. We examined whether induction of autophagy prolongs sevoflurane preconditioning protection during a longer ischemic insult. Isolated guinea pigs hearts were subjected to 30 or 45 min ischemia, followed by 120 min reperfusion (control). Anesthetic preconditioning was elicited with 2% sevoflurane for 10 min prior to ischemia (SEVO-30, SEVO-45). Chloramphenicol (autophagy upregulator, 300 µM) was administered starting 20 min before ischemia and throughout reperfusion in SEVO-45 (SEVO-45+CAP). To inhibit autophagy, 3-methyladenine (10 …

Cardiac Rehabilitation Programmes For Low-Risk Patients And Leisure Athletes: A Potential Paradox, Wendy Bjerke, Stu Steinman, Vincent Cotto

All PTHMS Faculty Publications

Background: Athletes are enrolled in cardiac rehabilitation (CR) programmes in small numbers and require unique diagnostic testing and training considerations. Additionally, many physiotherapists, exercise physiologists, athletic trainers and physicians lack experience treating athletes in CR due to their limited exposure to these types of patients. Content: This analysis distinguishes athletes from typical CR patients within the context of diagnostic testing, assessment, exercise prescription, and management. Several case studies present unique challenges and approaches to the rehabilitation of athletes in a CR setting. Conclusions: Athletes enrolled in CR should be treated and trained according to their abilities and goals. Combining traditional …

OBJECTIVES: To assess variation in feeding practice at hospital discharge after the Norwood procedure, factors associated with tube feeding, and associations among site, feeding mode, and growth before stage II.

STUDY DESIGN: From May 2005 to July 2008, 555 subjects from 15 centers were enrolled in the Pediatric Heart Network Single Ventricle Reconstruction Trial; 432 survivors with feeding data at hospital discharge after the Norwood procedure were analyzed.

RESULTS: Demographic and clinical variables were compared among 4 feeding modes: oral only (n = 140), oral/tube (n = 195), nasogastric tube (N-tube) only (n = 40), and gastrostomy tube (G-tube) only …

Galectin-1 In Early Acute Myocardial Infarction, Suhail Al-Salam, Satwat Hashmi

Department of Biological & Biomedical Sciences

Myocardial infarction (MI) is the most serious manifestation of coronary artery disease and the cause of significant mortality and morbidity worldwide. Galectin-1(GAL-1), a divalent 14.5-kDa protein, is present both inside and outside cells, and has both intracellular and extracellular functions. Hypoxia inducible factor-1 alpha (HIF-1α) is a transcription factor mediating early and late responses to myocardial ischemia. Identification of the pattern of expression of GAL-1 and HIF-1α in the heart during the first 24 hours following acute MI will help in understanding early molecular changes in this event and may provide methods to overcome serious complications. Mouse model of MI …

Update On Ranolazine In The Management Of Angina., J Nicolás Codolosa, Subroto Acharjee, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

Mortality rates attributable to coronary heart disease have declined in recent years, possibly related to changes in clinical presentation patterns and use of proven secondary prevention strategies. Chronic stable angina (CSA) remains prevalent, and the goal of treatment is control of symptoms and reduction in cardiovascular events. Ranolazine is a selective inhibitor of the late sodium current in myocytes with anti-ischemic and metabolic properties. It was approved by the US Food and Drug Administration in 2006 for use in patients with CSA. Multiple, randomized, placebo-controlled trials have shown that ranolazine improves functional capacity and decreases anginal episodes in CSA patients, …

Stress And Strain Adaptation In Load-Dependent Remodeling Of The Embryonic Left Ventricle, Christine Buffinton

Christine M Buffinton

Altered pressure in the developing left ventricle (LV) results in altered morphology and tissue material properties. Mechanical stress and strain may play a role in the regulating process. This study showed that confocal microscopy, three-dimensional reconstruction, and finite element analysis can provide a detailed model of stress and strain in the trabeculated embryonic heart. The method was used to test the hypothesis that end-diastolic strains are normalized after altered loading of the LV during the stages of trabecular compaction and chamber formation. Stage-29 chick LVs subjected to pressure overload and underload at stage 21 were reconstructed with full trabecular morphology …
