Goodbye Login Hello Heart Scan
2017/10/24
Forget fingerprint computer identification or retinal scanning. A University at Buffalo-led team has developed a computer security system using the dimensions of your heart as your identifier.The syst...
A team of biomedical engineering researchers, led by the University of Minnesota, has created a revolutionary 3D-bioprinted patch that can help heal scarred heart tissue after a heart attack. The disc...
3D-printed heart-on-a-chip with integrated sensors
3D-printed heart-on-a-chip integrated sensors
2016/11/4
Harvard University researchers have made the first entirely 3D-printed organ-on-a-chip with integrated sensing. Built by a fully automated, digital manufacturing procedure, the 3D-printed heart-on-a-...
Both cardiac cells in the heart and neurons in the brain communicate by electrical signals, and these messages of communication travel fast from cell to cell as 'excitation waves'. Interestingly, such...
Exercise Training Improves Heart Rate Variability after Methamphetamine Dependency
HRV SUBSTANCE,USE AUTONOMIC,NERVOUS,SYSTEM PARASYMPATHETIC,ACTIVITY
2017/5/23
Heart rate variability (HRV) reflects a healthy autonomic nervous system and is increased with physical training. Methamphetamine dependence (MD) causes autonomic dysfunction and diminished HRV. We co...
Atrial fibrillation ablation in patients with heart failure review
Atrial Fibrillation Ablation Heart Failure
2013/2/19
Atrial fibrillation and heart failure often coexist in patients with advanced heart failure symptoms. The result, in addition to a significant impact on quality of life, is an increase in the risk of ...
Spectrum of congenital heart diseases in an African population: A necropsy study
Congenital Heart Diseases Necropsy
2013/2/19
Background: The spectrum and incidence of congenital heart diseases amongst African population are not well defined in literature. There is the need to further elucidate the spectrum and epidemiology ...
Aged rat heart: Modulation of age-related respiratory defects decreases ischemic-reflow injury
Mitochondria Cytochrome Oxidase Complex III Myocardial Infarction Aging
2013/1/29
Myocardial injury increases in the elderly heart during ischemia and reperfusion. Mitochondria, the key targets and sources of injury during ischemia and reperfusion, sustain ischemic damage to the el...
Value of Orthostatic Hypotension as a Prognostic Bed-Side Test in Heart Failure
Orthostatic Hypotension Heart Failure
2013/2/20
Background: Neurohumoral compensatory mechanisms play an important role in stabilizing the functional activity of patients with heart failure using the arms of autonomic nervous system. Orthostatic Hy...
Impact of Mitral Valve Repair in Patients with End-Stage Congestive Heart Failure
Mitral Valve Repair Mitral Regurgitation Heart Failure
2013/2/20
Objective: The utility of mitral valve repair in patients with Mitral Regurgitation (MR) and advanced CHF remains controversial. Methods: 37 patients with MR and Left Ventricular Ejection Fraction (LV...
Lifestyle changes in coronary heart disease—Effects of cardiac rehabilitation programs with focus on intensity, duration and content—A systematic review
Coronary Heart Disease Secondary Prevention
2013/1/31
Background: Although coronary heart disease (CHD) is the most common cause of death worldwide the literature shows a wide variation in the arrangement of cardiac rehabilitation and achieved lifestyle ...

Malfunction Valve Mechanical Valve Thromboembolism
2013/2/20
Objective: Valve thrombosis defined as any thrombus not caused by infection attached to or near an operated valve that occludes part of the blood flow path and interferes with valve function. Treatmen...
Prediction of maximal heart rate percent during constant intensity efforts on trained subjects
Heart Rate Percent Treadmill Exercise Prediction Triangular Test
2013/1/30
The purpose of this study is to evaluate the relationship between %HRmax and %vVO2max at constant efforts made at different intensities. In randomized order, males healthy subjects (Age: 25 ± 7 years,...
