Nanoparticles - possible alternative to drug eluting stents
Researchers at MIT and Harvard Medical School have built targeted nanoparticles that can cling to artery walls and slowly release medicine, an advance that potentially provides an alternative to drug-releasing stents in some patients with cardiovascular disease.

Heart stem/progenitor cells improve mouse heart function after a heart attack
A team of researchers, at Tokyo Women's Medical University, Japan, and Chiba University Graduate School of Medicine, Japan, has found that transplanting sheets of clonally expanded heart cells expressing the protein Sca-1 (cells that are heart stem/progenitor cells and that the authors term CPCs) improves heart function after a heart attack in mice.

Delayed enhancement cardiovascular magnetic resonance to detect non-Q wave heart attacks
In a paper published by PLoS Medicine, Han W. Kim and colleagues from the Duke Cardiovascular Magnetic Resonance Center, United States of America, use a recently developed technique to detect heart damage in patients who don't have symptoms or abnormalities in the electrocardiogram (ECG) that are usually associated with a heart attack ( myocardial infarction ).

Bivalirudin during primary angioplasty better than heparin and glycoprotein IIb/IIIa inhibitors (GPI).
A study led by Gregg W. Stone, M.D., professor of medicine at Columbia University Medical Center/NewYork-Presbyterian and chairman of the Cardiovascular Research Foundation, has shown that heart attack patients who were administered the direct thrombin inhibitor bivalirudin during primary angioplasty had a reduced rate of adverse clinical events, a lower rate of major bleeding, and a lower mortality rate than those who were treated with a regimen of heparin and glycoprotein IIb/IIIa inhibitors (GPI).

Intermittent hypoxic treatment for reduced myocardial infarction and lethal arrhythmias
Researchers at the University of North Texas Health Science Center, Fort Worth, Texas have demonstrated that, contrary to prevailing dogma, hypoxia can be remarkably beneficial to the heart. These discoveries, to be reported in the June 2008 issue of Experimental Biology and Medicine, may lead to a new paradigm to protect hearts of patients at risk of coronary disease. Hypoxia is generally considered harmful to the heart, since a steady supply of oxygen is required to maintain cardiac function. However, this research has demonstrated that a 20 day program of brief, repetitive, moderate reductions in the amount of oxygen in the arterial blood induce adaptations which increase the heart’s resistance to the more severe insult of a heart attack.

Clopidogrel does not increase postoperative bleeding risk in patients with Acute Coronary Syndrome
Aspirin combined with clopidogrel is the treatment of choice for acute coronary syndromes. Although the maintenance of aspirin until surgery does not affect postoperative bleeding after coronary artery bypass graft (CABG) surgery, the latter may be dramatically increased when clopidogrel is continued over a period of 5 days preoperatively.

New genetic biomarkers could predict coronary heart disease
New genetic markers may be able to predict whether a person is likely to have coronary heart disease (CAD) in the future. Research carried out by Dr. M. Balasubramanyam and Dr.V.Mohan at the Madras Diabetes Research Foundation (India) shows that people who are pre-diabetic or who have Type 2 diabetes have much shorter telomeres1 and, since these people are prone to CAD, an early test could indicate their susceptibility and help them to alter their lifestyle to avoid or delay the onset of the disease. This work will be presented by Dr Adaikala Koteswari at the Society for Experimental Biologyâs Annual Main Meeting on Sunday 1st April 2007.

Adding abciximab to the antithrombotic regimen significantly reduces post-stent complications
Patients admitted to the hospital with an acute coronary syndrome (ACS) are often treated with a catheter-based procedure known as percutaneous coronary intervention, or PCI. But doctors are unclear about the optimal antithrombotic therapy to prescribe after procedure to prevent clotting, and new research suggests a possible alternative, according to a study presented today at the American College of Cardiology's 55th Annual Scientific Session. ACC.06 is the premier cardiovascular medical meeting, bringing together more than 30,000 cardiologists to further breakthroughs in cardiovascular medicine.

These findings, which are the first to establish a link between serotonin messages in the brain and atherosclerosis, could lead to an entirely new strategy for preventing heart disease and stroke, say the researchers.

Diabetic black men have less atherosclerosis
In a surprising outcome, investigators at Wake Forest University Baptist Medical Center found that diabetic black men have dramatically lower amounts of atherosclerosis, or hardening of the arteries, than diabetic white men.
This result was also observed in the face of increased thickness of carotid artery walls in black diabetic subjects. Increased wall thickness is widely accepted including by the U.S. Food and Drug Administration as a marker for atherosclerosis and a predictor of coronary heart disease, so the result was surprising.

C-reactive protein can be an early indicator of stiffened arteries
The Mayo Clinic collaborative study with researchers from the University of Michigan looked at 214 men and women with an average age of 59, who had no history of heart attack or stroke. Results suggest that low grade inflammation is associated with arterial stiffness (hardening). This inflammation may be a potential mechanism through which C-reactive protein is related to heart attack and stroke, and why testing for C-reactive protein in a blood test may be an effective early warning test for asymptomatic, or presymptomatic heart disease.
