New research shows that flu is a trigger of heart attacks

...ound that 11,892 people died from acute myocardial infarction (AMI) (47.8% men and 52.2% women), and 23,000 died from chronic ischaemic heart disease (IHD) (40.1% men and 59.9% women). The peaks in deaths from both AMI and IHD coincided with the times when influenza epidemics and acute respiratory disease (ARD)...

Protein therapy may reduce infarct size in heart attack patients

In a study presented today at the American College of Cardiology’s Innovation in Intervention: i2 Summit in New Orleans, La., a team from the Duke Clinical Research Institute presented the results from a Phase 1 study evalua...

Statins have neutral effect on risk of cancer

...ls, statins reduced the risk of a first myocardial infarction (heart attack) and overall mortality. With long-term follow-up and collection of cancer data in a majority of studies, insight into the risk of cancer among statin-naïve persons and statin users can be derived," the authors write. C. Michael White,...

Survival of heart patients on beta-blockers varies greatly with genetic variation

...ar says. "Data from patients with acute myocardial infarction have shown that beta-blockers are generally effective. They are known to decrease the size of the infarct and seem to prolong survival, on average." Recent research, however, reveals that variations in the beta-adrenergic receptor genes affect the b...
