Heart & Stroke Emergencies


It is important to know the signs and symptoms of a heart attack and stroke. The following information on angina, strokes and myocardial infarction can save your life or that of a loved one.

In the past few years, clot-busting drugs, angioplasty and other techniques have revolutionized the way paramedics and emergency room personnel treat heart and stroke emergencies. A few years ago, stroke victims were sent off for physical rehabilitation, but today, if the onset of a stroke can be detected rapidly, most victims can benefit from emergency drug therapy that can often reverse the debilitating effects of a stroke. The same drug therapy and treatment also applies to victims of certain types of heart attacks.
