Flu shot halves risk of heart attack or stroke in people with history of heart attack

The flu vaccine may not only ward off serious complications from influenza, it may also reduce the risk of heart attack or stroke by more than 50 per cent among those who have had a heart attack, according to new research led by Dr. Jacob Udell, a cardiologist at Women's College Hospital and clinician-scientist at the University of Toronto. What's more, the vaccine's heart protective effects may be even greater among those who receive a more potent vaccine. "Our study provides solid evidence that the flu shot helps prevent heart disease in vulnerable patients - with the best protection in the highest risk patients," Dr. Udell said. "These findings are extraordinary given the potential for this vaccine to serve as yearly preventative therapy for patients with heart disease, the leading cause of death among men and women in North America." Published recently in the Journal of the American Medical Association, the study reviewed six clinical trials on heart health in people who received the flu vaccine. The studies included more than 6,700 patients with a history of heart disease
