New therapy could preserve vessel function after heart attack

Scientists have identified the process that causes blood vessels to constrict during and after a heart attack. They've also demonstrated that delivering a vital molecule that is depleted during this process directly to those blood vessels can reverse damage and help restore blood flow. 
Pittsburgh scientists identify human source of stem cells with potential to repair muscle

For the first time, scientists at Children's Hospital of Pittsburgh of UPMC have discovered a unique population of adult stem cells derived from human muscle that could be used to treat muscle injuries and diseases such as heart attack and muscular dystrophy.

New research at The University of Nottingham is paving the way for techniques that use stem cells to repair the damage caused by heart attacks.
Air pollution link to clogged arteries

Should we be watching our exposure to airborne pollution as well as our cholesterol levels? Research now indicates that air pollution has a role to play in atherosclerosis (artery hardening), which can contribute to heart attacks or strokes.
Cardiac patches stimulate regeneration, improve function after heart attack

When human hearts are injured, as during a heart attack, healthy tissue normally can't regrow. Researchers now demonstrate in rats that a sponge-like patch, soaked in a compound called periostin and placed over the injury, can not only get heart cells to begin dividing and making copies of themselves again, but also improves heart function. Their findings appear in the July 15 online edition of Nature Medicine.
Metabolic syndrome -- don't blame the belly fat

Abdominal fat, the spare tire that many of us carry, has long been implicated as a primary suspect in causing the metabolic syndrome, a cluster of conditions that includes the most dangerous heart attack risk factors: prediabetes, diabetes, high blood pressure, and changes in cholesterol. But researchers have found that insulin resistance in skeletal muscle leads to alterations in energy storage that set the stage for the metabolic syndrome.
Depression lingers for female heart attack victims

Women who have suffered heart attacks have higher rates of lingering depressive symptoms compared to their male counterparts.
South Asian Scots have increased risk of heart attacks

Scots of South Asian descent are significantly more likely to suffer a heart attack than the rest of the Scottish population, according to a report published in the online open access journal BMC Public Health. The good news is that they are also more likely to survive this traumatic event than their non-Asian countrymen.
Blood pressure drugs may keep arteries clean: study

Blood pressure drugs beta-blockers can help keep arteries from clogging up, researchers said on Monday in a report that helps explain how the drugs prevent heart attack and sudden heart death.

The government gave hospitals around the country a public report card Thursday that measures their performance in the treatment of patients suffering from heart attacks or heart failure.
Estrogen is safe for most, new study finds
Reviver submitted, created time 1 year 5 months (www.chron.com)
The latest piece of evidence, in today's New England Journal of Medicine, shows that taking estrogen for seven years or more after menopause reduces calcification of the arteries — one of the key indicators of atherosclerosis — by as much as 60 percent. High levels of calcification are generally considered a predictor of increased risk for a heart attack.
Patients Weigh Options Amid Avandia Risk

"Pat Russo tried different drugs to control her diabetes before settling on Avandia, a widely prescribed diabetes pill now under scrutiny. She has taken it for three years, but on Tuesday phoned her doctor when she read news reports that it might raise the risk of heart attack."
Common Genetic Variation is Linked to Substantial Risk in Heart Attack

A common genetic variation on chromosome 9p21 is linked to a substantial increase in risk for heart attack, according to a new international research study. The findings are published today in the online edition of Science, and will appear in an upcoming printed edition of the journal.
A Genetic Clue to Heart Disease
newsdigg submitted, created time 1 year 6 months (sciencenow.sciencemag.org)
Researchers have used a new gene-hunting technique to pinpoint a novel genetic variant that raises some people's odds of having a heart attack. The results, reported online today in Science, suggest a possible new contributor to heart disease and could lead to a genetic test to pinpoint people who are susceptible.
Heart attack death rate in hospitals cut in half in 6 years
channel submitted, created time 1 year 6 months (www.cnn.com)
In just six years, death rates and heart failure in hospitalized heart attack patients have fallen sharply, most likely because of better treatment, the largest international study of its kind suggests.
