Hello student, in this question it mentions that a 65 year old patient has complained of chest pain during workout and there needs to be some tests done but before that the doctor also finds out that the person smokes.

So coming to the first question, the symptoms that shows he is suffering from coronary artery disease is based on the symptom that he is suffering or experiencing chest pain which leads to a lot of discomfort when the heart is under stress, when it has to do a lot of work when the heart rate goes up so the condition aggravates during that situation which suggests that he is suffering from coronary artery disease.
01:22
Why? because coronary artery disease is caused due to buildup in the coronary arteries which supplies blood to the heart and other parts of the body.
01:39
So because there is buildup, there can be blockage.
01:46
Because there is blockage, the heart needs to do more work, needs to pump more so that blood can be supplied to all parts of the body which is the reason why the person feels discomfort during exercise.
02:12
Coming to the next question, why is it important to test the heart under stress and not at rest? because when the heart is under stress and if tests are conducted then the test will be able to give accurate results about how well or how efficient the heart works under stress that is when it has to pump more blood.

So it is under this condition that the test will give a result whether the heart is healthy or not...
