Precision Medicine for Heart Failure: using ?omics? technologies to find the roa
09/12/2019 | Author: Kory J. Lavine MD, PhD and, Charles E. Canter, MD | Precision and personalized approaches to health care hold incredible promise to improve patient outcomes across the spectrum of health care disciplines.
Peripheral Artery Disease Supervised Exercise Therapy: Solvitur Ambulando
08/26/2019 | Author: Elizabeth Ratchford, MD, FSVM | Exercise plays a fundamental role in the treatment of peripheral artery disease (PAD) based on a wealth of data from clinical trials and meta-analyses dating back to the 1960s.
Hepatic Mechanisms of Action in the Triglyceride-Lowering Effect of Omega-3 Fatt
08/19/2019 | Author: Joanne Hsieh, PhD | The atherosclerotic cardiovascular disease (ASCVD) risk posed by hypertriglyceridemia has become clear with Mendelian randomization studies, which use genetic variants in the human population to naturally assign individuals to a ?control? or ?treatment? group.
Understanding Perfusion Evaluation in Critical Limb Ischemia: Mission Possible
08/12/2019 | Author: Tarek A. Hammad, MD | As per the 2016 AHA/ACC guidelines on the management of patients with lower extremity peripheral artery disease, critical limb ischemia was defined as ?a condition characterized by chronic (?2 week) ischemic rest pain, nonhealing wound/ulcers, or gangrene in 1 or both legs attributable to objectively proven arterial occlusive disease.?
Living in the Era of the Fontan: Failure Should Simply Not be an Option
07/01/2019 | Authors: Jordan D. Awerbach, MD, MPH & Richard A. Krasuski, MD | Pediatric and adult congenital cardiology have undergone dramatic changes over the past 50 years. Nowhere is this better illustrated than in the evolution of treatment for single ventricle anatomy. The Fontan circulation works off the premise that a subpulmonary ventricle is not required to advance blood through the pulmonary vascular bed.
Commentary: Diabetes and Heart Failure, the Double-Edged Sword: Strategies to Co
06/06/2019 | Author: Prakash Deedwania, MD, FAHA | Diabetes mellitus (DM) and Heart Failure (HF) are major public health problems that are increasing throughout the world.
AHA Statement on HIV and Cardiovascular Disease: Clinical Strategies and Future
06/03/2019 | Author: Virginia A. Triant, MD, MPH | Widespread use of antiretroviral therapy (ART) coupled with strategies to expand testing and promote engagement in care has transformed human immunodeficiency virus (HIV) to a chronic disease with a near-normal lifespan.
Evolving Classification and Diagnostic Schemes in Childhood Cardiomyopathies
05/28/2019 | Author: Susan W. Denfield, MD | Since the original phenotypic classification of cardiomyopathies by the World Health Organization (WHO), as dilated (DCM), hypertrophic (HCM) and restrictive (RCM), a number of revised classification schemes have been proposed and published. In the 1980 WHO report cardiomyopathies were defined as heart muscle diseases of unknown cause, while heart muscle disease with a known cause (infective, metabolic/endocrine, storage or infiltrative diseases) were labeled as specific heart muscle disease.
Clinical Cardiovascular Genetics Programs: A Call to Action and a Roadmap
05/23/2019 | Author: Svati H. Shah, MD, MS, MHS, FAHA | I often ask my clinical colleagues, ?How often do you diagnose a patient with a monogenic disease?? Recent attention has been focused on the hope of precision medicine and understanding how genetics contributes to common disease risk and drug response.
The Past, Present, and Future of Cardiac Rehabilitation
05/13/2019 | Nanette Kass Wenger, MD, MACC, MACP, FAHA, MAACVPR | Cardiac rehabilitation is defined as ?the provision of comprehensive long-term services involving medical evaluation; prescriptive exercise; cardiac risk factor modification; and education, counseling, and behavioral interventions.
A Food Systems Perspective for Helping to Achieve AHA Dietary Goals
04/29/2019 | Author: Christopher Gardner, PhD | Food and health are interconnected in many complex ways. Unraveling the complexities involves looking at these connections from multiple perspectives. Nutrients important for health are usually consumed in the context of foods. A characteristic combination of foods can be identified as a food pattern (e.g., Mediterranean).
Exercise-focused Rehabilitation for Cancer Survivors: Creating a CORE Component
04/08/2019 | Author: Kim Dittus, MD, PhD | The publication of the AHA statement, Cardio-Oncology Rehabilitation (CORE) to Manage Cardiovascular Outcomes in Cancer Patients and Survivors, represents a breakthrough for exercise to become standard of care for cancer survivors. Incorporating exercise as part of cancer care has taken a long time.
Insights from the AHA Scientific Statement on Managing Arrhythmias in Patients w
04/04/2019 | Author: Jim Cheung, MD, FACC, FHRS | Left ventricular assist devices (LVADs) have become a mainstay therapy for patients with advanced heart failure by significantly reducing morbidity and mortality. Consequently, the use of LVADs has increased rapidly over recent years.
Myocardial Infarction without Coronary Arterial Obstruction: The Mysterious MINO
03/27/2019 | Author: Joseph S. Alpert, MD | The first time that I heard the term MINOCA, it made me think that perhaps this referred to an ancient civilization in Greece contemporaries of the Minoans on Crete. I imagined the following headline: ?Archeologists unearth the remains of one of the cities of Minoca in northern Greece?. Of course, for cardiologists, MINOCA has nothing to do with ancient Greece.
Are the Lessons Learned From Animal Models of Hypertension Applicable to the Cli
03/14/2019 | Author: Patricia Martinez Quinones, MD and R Clinton Webb, PhD, FAHA | One in three adults in the U.S. has diagnosed high blood pressure. However, taking into consideration the 2017 Hypertension Clinical Guidelines by the AHA and ACC, 130/80 mm Hg rather than 140/90 mm Hg is considered elevated arterial blood pressure.
