Medical researchers are increasingly turning to mobile devices such as smartphones and watches as a way to monitor patients in trials, an approach they hope improves participation and accuracy but that also has limitations.
If the tactic catches on, it could prove another selling point for products such as Apple Inc.’s watch, which thus far has failed to gain the type of widespread adoption the iPhone and iPad have enjoyed.
The company last week released an app that will enable it to test the Apple Watch’s ability to track irregular heart rhythms as part of a study done in collaboration with Stanford University researchers. The study is the latest aiming to tap the ubiquity…

Apple's study doesn't directly address USPSTF's biggest concern. "The million-dollar question, the one we really need to have answered, is whether people who screen for arrhythmias have fewer strokes, long-term, than those who don't," Landefeld says. The present study is designed primarily to see how Apple’s AF detection compares with a dedicated heart monitor—not how the people who receive AF alerts fare in the long haul.
The findings were published in the journal PLOS Biology. The team focused on a protein called p27, which is known among other things to influence the cell cycle. The team found that caffeine triggered the movement of p27 into the mitochondria of heart cells in mice, and in particular, the migration of the heart’s endothelial cells, which line the blood vessels. How well the endothelial cells were able to migrate, they found, relied strongly on the presence of p27, which again is bolstered by caffeine. The protein also had a couple of other cardiovascular benefits: It protected heart muscle cells from dying after heart attack was induced in some of the mice. And it triggered one type of cells, fibroblasts, to differentiate into cells containing contractile fiber, essential for good heart function.
Women are needlessly dying because research and treatment of cardiovascular disease is focused on men. It's time for equity in heart health as well as in Hollywood.
In this nationwide real world study covering 16 years of hospital admissions for myocardial infarction with symptom onset documented to the nearest minute, Christmas, and Midsummer holidays were associated with higher risk of myocardial infarction, particularly in older and sicker patients, suggesting a role of external triggers in vulnerable individuals.
Meta-analysis of 11 aspirin therapy clinical trials finds no reduction in cardiovascular events, increased risk of major bleeding.

You’ve most likely heard of medical reports touting the effectiveness of a diet plan, a new drug, a supplement, or medical procedure. You may have even decided on a course of action based on these findings, only to find out later that they have been refuted by new studies.
Strikingly, the odds are that the studies that influenced your decision, and possibly the decision of your doctor, were wrong.
For Dr. Piero Anversa, the fall from scientific grace has been long, and the landing hard. Researchers worldwide once hailed his research as revolutionary, promising the seemingly impossible: a way to grow new heart cells to replace those lost in heart attacks and heart failure, leading killers in the United States. But Harvard Medical School and Brigham and Women’s Hospital in Boston, his former employers, this month accused Dr. Anversa and his laboratory of extensive scientific malpractice.
According to new research published in European Heart Journal: Acute Cardiovascular Care from the European Society of Cardiology, women wait longer than men to get help when they have cardiovascular problems. Researchers notes in a recent press release about the study that people often think that heart attacks mostly happen to men, but they’re just as common in women. In fact, heart disease is the leading cause of death in both men and women, according to the press release.
Many people routinely take nutritional supplements such as vitamin D and fish oil in the hopes of staving off major killers like cancer and heart disease. But the evidence about the possible benefits of the supplements has been mixed. Now, long-awaited government-funded research has produced some of the clearest evidence yet about the usefulness of taking the supplements. And the results — published in two papers — are mostly disappointing.
Analysis: Brexit will have an impact both on patients needing drug trials and academics seeking funding, says health correspondent Alex Matthews-King
Company’s app will enable it to test smartwatch’s ability to track irregular heart rhythms as part of a study with Stanford.
Since 1949, the AHA has invested more than $4.3 billion in research
to enhance our knowledge of cardiovascular diseases and stroke.
We fund life-saving heart research and work to improve heart disease prevention and care for all Australians.
The Heart Research Institute is an internationally recognised medical research institute that performs groundbreaking cardiovascular research. Our work stretches far and wide.
We inspire and invest in pioneering medical research, ground-breaking training and education, and in communities to improve their heart health for themselves. They are things we’re proud to have done for over 50 years and pushes us to do more.
The mission of the ISHR is to promote the discovery and dissemination of knowledge in the cardiovascular sciences on a world-wide basis.
MCRF's mission is to prolong and improve the quality of life in the communities we serve by conducting and disseminating findings of high quality cardiovascular clinical research.
Cardiovascular disease (CVD) is the number one killer of women in the United States. Long thought of as primarily affecting men, we now know that CVD including heart disease, hypertension, and stroke also affects a substantial number of women. Experts estimate that one in two women will die of heart disease or stroke, compared with one in 25 women who will die of breast cancer.
Australian Heart Research (AHR) is passionate and determined to improve heart health and #beatheartdisease through advances in knowledge and research.
