Researchers at Johns Hopkins have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells turn out to share similar means for regulating ion intake, they say. Both types of channels are critical to life. Having the right concentrations of sodium and calcium ions in cells enables healthy brain communication, heart contraction and many other processes. The new evidence is likely to aid development of drugs for channel-linked diseases ranging from epilepsy to heart ailments to muscle weakness.
By analyzing the number of times scientists were cited in others’ papers, the company Thomson Reuters has created a new list of the top 3,215 most highly cited—and therefore most influential— researchers in the world. Seventeen are from the Johns Hopkins University School of Medicine.
New animal studies by Johns Hopkins cardiovascular researchers strongly suggest that sildenafil, the erectile dysfunction drug sold as Viagra and now under consideration as a treatment for heart failure, affects males and females very differently.
Traditional first-line checks of such heart disease risk factors as cholesterol, blood pressure and smoking habits aren’t nearly good enough to identify cardiovascular disease in otherwise healthy, young firefighters, according to results of a small Johns Hopkins study.
A type of cell that builds mouse hearts can renew itself, Johns Hopkins researchers report. They say the discovery, which likely applies to such cells in humans as well, may pave the way to using them to repair hearts damaged by disease — or even grow new heart tissue for transplantation.
Men with long-term HIV infections are at higher risk than uninfected men of developing plaque in their coronary arteries, regardless of their other risk factors for coronary artery disease, according to results of a study led by Johns Hopkins researchers. A report on the research appears in the April 1 issue of Annals of Internal Medicine.
In a study that began in a pair of infant siblings with a rare heart defect, Johns Hopkins researchers say they have identified a key molecular switch that regulates heart cell division and normally turns the process off around the time of birth. Their research, they report, could advance efforts to turn the process back on and regenerate heart tissue damaged by heart attacks or disease.
A new study shows that coronary artery calcium (CAC) screening, an assessment tool that is not currently recommended for people considered at low risk, should play a more prominent role in helping determine a person's risk for heart attack and heart disease-related death, as well as the need for angioplasty or bypass surgery. CAC screening provides a direct measure of calcium deposits in heart arteries and is easily obtained on a computed tomography (CT) scan.
Johns Hopkins researchers have developed a more accurate way to calculate low-density lipoprotein (LDL) cholesterol, the so-called "bad" form of blood fat that can lead to hardening of the arteries and increase the risk of heart attack and stroke. If confirmed and adopted by medical laboratories that routinely calculate blood cholesterol for patients, the researchers say their formula would give patients and their doctors a much more accurate assessment of LDL cholesterol.
A new study highlights the importance of exercise and physical fitness among people with stable coronary artery disease. Researchers at the Johns Hopkins University School of Medicine and Henry Ford Hospital found that higher levels of physical fitness lower the risk of having heart attacks and increase survival in those with coronary artery disease, whether or not they have had a procedure to open up their blocked arteries.
A review of dozens of studies on the use of statin medications to prevent heart attacks shows that the commonly prescribed drugs pose no threat to short-term memory, and that they may even protect against dementia when taken for more than one year. The Johns Hopkins researchers who conducted the systematic review say the results should offer more clarity and reassurance to patients and the doctors who prescribe the statin medications.
Johns Hopkins Medicine has teamed up with a local philanthropic foundation to provide automated external defibrillators (AEDs), to 10 Baltimore City middle schools for use, if needed, during sporting events and practices. The portable devices, which are used to shock the heart back into a normal rhythm, can save the life of a student athlete, coach or spectator who collapses during practice or a game due to a heart rhythm disorder that causes sudden cardiac arrest.
Irene Pollin, a passionate health advocate and founder of a national organization devoted to heart disease prevention in women, has made a $10 million gift to the Ciccarone Center for the Prevention of Heart Disease. Her donation also establishes the Kenneth Jay Pollin Professorship in Cardiology and will launch pivotal research on heart disease prevention.
A large, multi-center study led by Johns Hopkins researchers has found a significant link between lifestyle factors and heart health, adding even more evidence in support of regular exercise, eating a Mediterranean-style diet, keeping a normal weight and, most importantly, not smoking.
In what promises to be an eye-opener for many doctors and patients who routinely depend on cholesterol testing, a study led by researchers at the Johns Hopkins University School of Medicine found that the standard formula used for decades to calculate low-density lipoprotein (LDL) cholesterol levels is often inaccurate.

A detailed study of heart muscle function in mice has uncovered evidence to explain why exercise is beneficial for heart function in type 2 diabetes. The research team, led by scientists at the Johns Hopkins University School of Medicine, found that greater amounts of fatty acids used by the heart during stressful conditions like exercise can counteract the detrimental effects of excess glucose and improve the diabetic heart’s pumping ability in several ways. The findings also shed light on the complex chain of events that lead to diabetic cardiomyopathy, a form of heart failure that is a life-threatening complication of type 2 diabetes.
It is a cellular component so scarce, some scientists even doubted its existence, and many others gave up searching for its molecular structure. Now a team led by researchers at Johns Hopkins has defined the protein structural composition of mitoKATP, a potassium channel in the mitochondria of the heart and other organs that is known to protect against tissue damage due to a heart attack or stroke. Importantly, the newly found channel strongly improves heart cell survival, demonstrating an essential life-saving role.
Since its founding, The Johns Hopkins Hospital has broken new ground, led the field in medicine and made history in countless ways. Just one of the hospital’s many historic achievements is that it was consecutively ranked #1 in the nation for 21 years out of the 23 in which U.S. News & World Report has held its annual rankings of U.S. hospitals. This year, the hospital is again ranked #1 nationally in five specialties, and it is ranked #2 overall in the nation.
Johns Hopkins researchers have discovered that a single protein molecule may hold the key to turning cardiac stem cells into blood vessels or muscle tissue, a finding that may lead to better ways to treat heart attack patients.
Years of planning, construction and designing every detail of a magnificent, 1.6-million-square-foot hospital building finally came to fruition on May 1 when The Johns Hopkins Hospital officially opened the new facility. A carefully choreographed move of several hundred patients from the original Johns Hopkins Hospital into The Charlotte R. Bloomberg Children’s Center and the Sheikh Zayed Tower took place on April 29 and 30, right before the official opening.
A seminar and workshops on the latest research advances and treatments for a heart condition known as ARVD—one of the leading causes of sudden death among teenagers, young adults and young athletes. More than 200 patients and their family members from 25 states across the U.S. and Canada will attend.
Patients with heart and vascular disease will be cared for in spacious, state-of-the-art private rooms when Johns Hopkins opens its new building to the first patients on April 29. The Johns Hopkins Heart and Vascular Institute occupies a major part of the 1.6 million-square-foot facility, which has 560 all-private patient rooms with private baths and 33 expansive operating rooms.
JWriting the first commentary for a new feature in the Journal of the American Medical Association (JAMA), called Viewpoint, Johns Hopkins cardiologists make the case for why a 55-year-old man with a 10 percent estimated risk of heart attack over the next 10 years should be offered statin medication. They were invited to debate a professor who argues against prescribing statins for "primary" prevention-for those who have not had a cardiovascular event, such as a heart attack-even though they may be considered at "intermediate" risk because of elevated cholesterol or other factors. Readers are then invited to vote on which viewpoint they endorse.
Patients who have non-emergency angioplasty to open blocked heart vessels have no greater risk of death or complications when they have the procedure at hospitals without cardiac surgery backup. That is the conclusion of a national a study to assess the safety and effectiveness of such procedures at community hospitals.
Overweight people who shed pounds, especially belly fat, can improve the function of their blood vessels no matter whether they are on a low-carb or a low-fat diet, according to a study being presented by Johns Hopkins researchers at an American Heart Association scientific meeting in San Diego on March 13 that is focused on cardiovascular disease prevention.
Coronary calcium in heart arteries provides important clues about risk, even among younger and elderly patients and those without traditional risk factors, according to new studies.
A team of Johns Hopkins researchers has uncovered further evidence of the benefits of a balanced diet that replaces white bread and pasta carbohydrates with unsaturated fat from avocados, olive oil and nuts — foods typical of the so-called “Mediterranean diet.”
If your doctor says you have a negative stress test, or that your cholesterol or blood pressure are normal, how assured can you be that you're not likely to have a heart attack in the next seven to 10 years? Assessing traditional risk factors, such as age, high blood pressure, cholesterol, smoking and family history can estimate a person's risk, but the picture is not always clear-cut. Some newer tests can be offered to provide reassurance or guidance about the need for medications or further testing.
Hospitals that do not have cardiac surgery capability can perform nonemergency angioplasty and stent implantation as safely as hospitals that do offer cardiac surgery. That is the finding of the nation’s first large, randomized study to assess whether patients do just as well having nonemergency angioplasty performed at smaller, community hospitals that do not offer cardiac surgery.
Doctors at Johns Hopkins have shown that during an increasingly popular type of breast-reconstruction surgery, they can safely preserve the internal mammary artery, in case it is needed for future cardiac surgery.
Magnetic Resonance Imaging (MRI), an important diagnostic test, has traditionally been off limits to more than 2 million people in the United States who have an implanted pacemaker to regulate heart rhythms or an implanted defibrillator to prevent sudden cardiac death. Now, in a study published in the October 4 issue of Annals of Internal Medicine, cardiologists at Johns Hopkins report that a protocol they developed has proved effective in enabling patients with implanted cardiac devices to safely undergo an MRI scan.
Each year in the United States, more than 200,000 people have a cardiac defibrillator implanted in their chest to deliver a high-voltage shock to prevent sudden cardiac death from a life-threatening arrhythmia. While it’s a necessary and effective preventive therapy, those who’ve experienced a defibrillator shock say it’s painful, and some studies suggest that the shock can damage heart muscle.
Johns Hopkins experts in arrhythmogenic right ventricular dysplasia (ARVD) have defined a set of criteria that could be used to assess a patient’s need for an implanted defibrillator to prevent sudden death. In a study to be published in the September 27 issue of the Journal of the American College of Cardiology that is now online, the researchers report that using those criteria, they were able to separate the patients at high risk for a life-threatening irregular heart rhythm from those with low risk.
Heart specialists at Johns Hopkins have figured out how a widely used pacemaker for heart failure, which makes both sides of the heart beat together to pump effectively, works at the biological level. Their findings, published in the September 14 issue of Science Translational Medicine, may open the door to drugs or genetic therapies that mimic the effect of the pacemaker and to new ways to use pacemakers for a wider range of heart failure patients.
The presence of calcium in coronary arteries is a much better predictor of heart attack and stroke than C-reactive protein among people with normal levels of LDL cholesterol, according to a study of more than 2,000 people led by a Johns Hopkins heart specialist.
Johns Hopkins scientists have launched a pioneering research program to create, for the first time, human platelet cells from stem cells in order to study inherited blood clotting abnormalities ranging from clots that cause heart attacks and stroke to bleeding disorders.

Tomaselli, M.D., professor and director of the Division of Cardiology at the Johns Hopkins University School of Medicine, will become president of the American Heart Association (AHA), the nation’s leading voluntary health organization focused on cardiovascular disease and stroke, on July 1.
Overweight and obese people looking to drop some pounds and considering one of the popular low-carbohydrate diets, along with moderate exercise, need not worry that the higher proportion of fat in such a program compared to a low-fat, high-carb diet may harm their arteries, suggests a pair of new studies by heart and vascular researchers at Johns Hopkins.
Coronary computed tomographic (CT) angiography, which can detect plaque buildup in heart vessels, is sometimes used as a screening tool to assess the risk for a heart attack. However, the usefulness of the test on low-risk patients who do not have coronary symptoms, such as chest pain, has been unclear.
Harry C. “Hal” Dietz, III, M.D., the Victor A.

A study of more than 14,000 men and women whose hearts stopped suddenly suggests that the chances of survival are very high if such cardiac arrests are witnessed in large public venues, including airports, sports arenas or malls. The reasons, researchers say, are that almost four out of five such cases appear to be due to a survivable type of heart rhythm disruption and that big places with lots of people are more likely to have an automated external defibrillator, or AED device, handy, along with those who can apply it as well as CPR.
A study among almost 50,000 people worldwide has identified DNA sequence variations linked with the heart’s electrical rhythm in several surprising regions among 22 locations across the human genome.
