Computer Versus Human in Interpreting Echocardiograms

On single still images drawn from all 15 views, the model achieved an average overall accuracy of 91.7 percent  compared to an average of 79.4 percent for board-certified echocardiograpers classifying a subset of the same test images.   Highlights Computers Are More Accurate Than Echocardiographers in Interpreting Echocardiograms Imaging is a critical part of medical diagnosis; Interpreting medical images typically requires extensive training and practice and is a complex and time-intensive process Deep learning, specifically using convolutional neural networks (CNNs), is… Keep Reading

Height and Heart Disease Risk

  Lower than Average Height Increases Risk of Heart Disease   Highlights For every 2.5 inches below average height, risk of heart disease increased about 14 percent; this was more pronounced in men than women.  200,000 people in the United Kingdom were studied. For every 2.5 inches below average height, risk of heart disease increased about 14 percent; this was more pronounced in men than women.   The risk of getting heart disease due to your height is much less than… Keep Reading

Five Early Warning Signs of a Heart Attack

Highlights Early Warnings Symptoms of a Heart Attack Dr. O’Keefe-McCarthy cited a number of previous studies that have suggested women tend to experience more warning symptoms compared with men. Women tend to experience less prodromal chest pain, but reported more episodes of fatigue, anxiety, and head-related symptoms such as headache or dizziness compared with their male counterparts. Dr. McSweeney and her colleagues identified the five specific prodromal symptoms that appear to be most predictive of future cardiac events: –Unusual fatigue –Discomfort in… Keep Reading

Most Diagnostic Tests Miss Heart Attacks

  63% of the myocardial infarctions identified by cardiosvacular medical imaging were missed in routine medical care,  Highlights Most Heart Attacks Are Missed in Routine Medical Care Unrecognised heart attacks  refer to sub-clinical events that are missed in routine medical care but are picked up by electrocardiogram (ECG) or by cardiovascular magnetic resonance (CMR) imaging, which is more accurate.  63% (156 out of 247) of the myocardial infarctions identified by CMR were missed in routine medical care,” said Dr Acharya.… Keep Reading

Effects of Weather on Heart Failure

 Lag effects of temperature and other meteorological parameters on heart failure events were limited but present.  -Highlights- Dropping temperatures and changes in atmospheric pressure can lead to an increase in the risk of heart failure for elderly people. We measured the lag effects of temperature, relative humidity, atmospheric pressure and fine particulate matter (PM2.5) on hospitalizations and deaths for heart failure in elderly diagnosed with this disease on a 10-year period in the province of Quebec, Canada. We observed an… Keep Reading
