Now research conducted in fruit flies, rats and monkeys by scientists at Johns Hopkins, UC San Diego, and other institutions reveals that levels of a protein called vinculin increase with age to alter the shape and performance of cardiac muscle cells — a healthy adaptive change that helps sustain heart muscle vitality over many decades.
Despite the intense activity and high hopes that surround the use of stem cells to reverse heart disease, scientists still face multiple roadblocks before the treatment will be ready for clinical prime time. Researchers are now finding ways to maximize the healing potential of stem cells by helping them overcome the inhospitable conditions of a damaged heart – bringing the promise of stem cell therapy for heart disease one step closer to reality.
For healing the heart after a heart attack, stem cell therapies show promise but are slow to implement. Researchers develop a new treatment called microsphere therapy that can be kept on-hand and administered more readily than stem cells.

It may be better for patients to resume taking their blood pressure medication sooner after surgery than previously thought. A new study published in the Online First edition of Anesthesiology, the official medical journal of the American Society of Anesthesiologists® (ASA®), found resuming angiotensin receptor blockers (ARBs), common medications used to treat high blood pressure, within two days after surgery decreased death rates in the first month following surgery.
Day in and day out, millions of people with diabetes test their blood sugar levels. And many may wonder if all the careful eating, exercise and medication it takes to keep those levels under control is really worth it. A major new study should encourage them to keep going -- and prompt them to work with their doctors on reducing their cardiovascular risk.
After reviewing outcomes from thousands of cases, researchers at Johns Hopkins report that patients with blocked neck arteries who undergo carotid stenting to prop open the narrowed blood vessels fare decidedly worse if their surgeons re-inflate a tiny balloon in the vessel after the mesh stent is in place.
Few heart specialists make use of published information about interactions between drugs used to treat cardiovascular disease and the genetic variations that affect how patients respond to them. So physicians at U Chicago and Stanford combed through the literature on the pharmacogenomics of the leading cardiovascular drugs and compiled summaries.
The importance of preventing hypertension is reinforced by a study showing anti-hypertension medicines can increase stroke risk by 248 percent, according to new UAB School of Public Health research published in the journal Stroke.
A new report from UAB demonstrates that clinical and genetic factors affecting dose requirements for warfarin vary by race. The study, published online today in Blood, proposes race-specific equations to help clinicians better calculate warfarin dosage.
Simple measures of kidney function and damage may be just as good at predicting who is at risk for heart failure and death from heart attack and stroke as traditional tests of cholesterol levels and blood pressure, new Johns Hopkins Bloomberg School of Public Health-led research suggests.
HDL, the “good cholesterol” helps remove fat from artery walls, reversing the process that leads to heart disease. Yet recent drug trials and genetic studies suggest that pushing HDL levels higher doesn’t reduce the risk of heart disease. Now, an epidemiological study shows that a person’s HDL function—the efficiency of HDL molecules at removing cholesterol—may be a better measure of coronary heart disease risk and target for heart-protecting drugs.
Carbon monoxide is typically associated with brain injury and neurological symptoms. But a new study led by investigators at Beth Israel Deaconess Medical Center suggests that when administered in small, carefully controlled amounts, CO may actually protect the brain from damage following hemorrhagic stroke.

A diabetes drug may have benefits beyond lower blood sugar in patients with HIV. New research from Washington University School of Medicine in St. Louis suggests the drug may prevent cardiovascular problems because it works to reduce inflammation that is linked to heart disease and stroke in these patients. The drug both improved metabolism and reduced inflammation in HIV-positive adults on antiretroviral therapy.
Adults over 50 who have persistent symptoms of depression may have twice the risk of stroke as those who do not, according to a new study led by researchers at Harvard T.H. Chan School of Public Health. Researchers found that stroke risk remains higher even after symptoms of depression go away, particularly for women.

The culmination of two decades of research, a new study reveals the genetic causes of a curious, rare syndrome that manifests as hypertension (high blood pressure) accompanied by short fingers (brachydactyly type E). Six, unrelated families with the syndrome come from across the globe – United States, Turkey, France, South America, and two from Canada – yet share mutations that cluster in a small region of phosphodiesterase 3A (PDE3A). Functional studies imply the mutations change resistance of blood vessels, an underappreciated mechanism for regulating blood pressure. The findings, published in Nature Genetics, suggest new directions for investigating causes of hypertension in the general population.
The Lariat device is associated with a significant incidence of death and urgent cardiac surgery during its frequent off-label use to prevent stroke in patients with the irregular heartbeat known as atrial fibrillation. Following a systematic review of case reports and an FDA safety database, researchers are calling for formal controlled investigations into the safety and efficacy of off-label use of the Lariat device, which has never been approved for treatment of this condition.
Frailty among older people with cardiovascular disease appears to be more predictive than age for gauging their risk of heart attack, stroke and death, according to an international study that included researchers at Duke Medicine.
