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.
Hopkins Study Finds MRI Tests Safe for People with Implanted Cardiac Devices When Certain Guidelines ...
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.
Contradicting the long-held medical belief that the risk of cardiovascular death for women spikes sharply after menopause, new research from Johns Hopkins suggests instead that heart disease mortality rates in women progress at a constant rate as they age.
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.
