rapid style of speech. A sense of time urgency leads to restlessness, impatience, and acceleration of most activities. This in turn may result in irritability and the enhanced potential for type-A hostility and anger. Type-A individuals are thus at an increased risk of developing coronary heart disease. The type-A behaviour pattern is defined as an action-emotion complex involving10: (1) behavioural dispositions (e.g., ambitiousness, aggressiveness, competitiveness, and impatience). (2) specific behaviours (e.g., muscle tenseness, alertness, rapid and emphatic speech stylistics, and accelerated pace of most activities). (3) emotional responses (e.g., irritation, hostility, and anger). Comparatively, type-A persons are more risky to develop coronary heart disease than type-B

individuals, whose manners and behaviours are relaxed. The risk, however, is independent of the risk factors. Not all physicians are convinced that type-A behaviour pattern is a risk factor, and thousands of studies and researches are currently being done by experts on this topic. THE CARDIAC REHAB PROGRAM This program at the Credit Valley Hospital is designed to help patients with coronary artery disease lower their overall risk, and to prevent any further attacks. It provides rehabilitation for patients who are likely to have heart attacks, have had heart attacks, or had a recent surgery. Most patients come to this one-hour class two nights a week, which takes place outside the physiotherapy department. The class is ran by volunteers, and is usually supervised by a

kinesiologist. The patients come in a little before 6:00 pm, and have their blood pressure taken. At six o’clock, volunteers will take the patients through a fifteen-minute warm-up. After the warm-up, the patients will go on with their exercise for half an hour. The patients can choose from walking, rowing machines, stationary bicycles, and arm ergometer, or a combination of two or more as their exercise. Each patient is reassessed once a month, in order to keep track of their progress. Volunteers will ask the patient being reassessed a series of questions, which includes frequency of exercise, type of exercise program, problems with exercise, etc. About 6:30, when the patients are near the peak of their exercise, the ones being reassessed will have to have their pulse and

blood pressure measured; to see if they have reached their “target heart rate”, and to see if their blood pressure goes up as expected. At about 6:45, the patients end their exercise and cool-down begins. Cool-down is in a way similar to warm-up, only this helps the patients to relax their hearts, as well as their body after a half-hour workout. After cool-down most patients have their blood pressure taken again just to make sure nothing unusual occurs. CONCLUSION Angina pectoris is not a disease which affect a person’s heart permanently, but to encounter angina pain means something is wrong. The pain is the heart’s distress signal, a built-in warning device indicating that the heart has reached its maximum workload. Upon experiencing angina, precautions should be taken.

A person’s lifestyle plays a major role in determining the chance of developing heart diseases. If people do not learn how to prevent it themselves, coronary artery disease will remain as the single biggest killer in the world, by far.
