This past weekend, two veteran law enforcement officers suffered fatal heart attacks while running the Los Angeles Marathon. They demonstrate the three to four-fold increase in risk of sudden cardiac death in men compared to women. An estimated 6% to 17% of all sudden cardiac deaths in men occur during extreme exertion.
Not only […]

Care After Heart Attack Not Fair

If you’re a woman, a member of a minority group, or one of the elderly, take care to find a doctor who truly understands and respects your special needs. In a recent study, researchers found people in these categories are less likely to receive adequate care after a heart attack. They are often taken […]

Public Defibrillators Save Lives

Defibrillators may soon be saving lives all over Canada. Various health initiatives, including the Durham Cardiac Safe Community Program, want to place defibrillators in public places, such as sports arenas and shopping malls.
Not only do the defibrillators save lives upon immediate use, they also send a signal to emergency workers automatically when they’re removed […]

Homocysteine and Heart Attacks

One of the frustrating things about studying heart disease is the lack of consistent data regarding risk factors. In two recent studies presented at the American College of Cardiology annual meeting, lower levels of homocysteine did NOT appear to decrease the risk of heart disease and stroke. These findings contradict the study I presented […]

Folic Acid Reduces Death from Stroke

Stroke mortality rates in both the United States and Canada dropped after folic acid fortification of enriched grain products, such as cereals and breads, took place in 1998. In England and Wales, where no folic acid fortification took place, no change in the rate of deaths from stroke was observed. Folic acid appears […]

Pregnancy complications were associated with:

Smoking Bans in Ireland Reduce Coronary Heart Disease Deaths

Next year, smoking will be banned in UK pubs, clubs and workplaces. The ban should result in a drop in deaths from coronary artery heart disease. Ireland, which banned smoking in public places in 2004, has already observed a 50% decrease, partly attributable to lifestyle changes, especially smoking and diet.
I don’t think anyone […]

Statin Drug Rosuvastatin Reverses Atherosclerosis

Statin drugs, such as rosuvastatin aka Crestor, are commonly prescribed to lower blood cholesterol levels and stabilize fatty plaques in arteries. New evidence suggests that high doses of rosuvastatin may go one step further to break down fatty deposts and reverse atherosclerosis.
Instead of the usual 10 mg or 20 mg dose per […]

Anti-Clotting Drug Plavix Has No Clear Benefit

If one is good and another too, together they must be doubly good?! Not so in the case of anti-clotting drug Plavix. In combination with aspirin, it did not prevent heart attacks in high risk people any better than aspirin alone.
Dr. Marc A. Pfeffer of Harvard Medical School and Dr. John A. Jarcho […]
