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.

Myocardial Infarction and Heart Attack


Myocardial infarction is often called a 'Heart Attack'. Also known as an M.I., a myocardial infarction results from a lack of blood flow to an area of the heart causing the destruction of heart muscle tissue to occur .

What causes a heart attack?

A heart attack occurs when the blood supply to the heart is either partially or completely blocked. The blockage can be caused by plaque buildup (deposits of fat like substances) in one or more of the coronary arteries that are responsible for feeding the heart muscle. The plaque can rupture or tear creating a blockage. With the blood flow to the heart completely blocked the cells of the heart are then deprived of their much needed oxygen and nutrients, death of heart tissue results.
