advancement.

(4) a continuous involvement in multiple and diverse

functions subject to time restrictions.

(5) habitual propensity to accelerate the rate of

execution of most physical and mental functions.

(6) extraordinary mental and physical alertness.

(7) aggressive and hostile feelings.

The enhanced competitiveness of type-A persons leads to an

aggressive and ambitious achievement orientation, increased mental

and physical alertness, muscular tension, and an explosive and

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.
