Q. How CAD Patients Response in Hypertenstion?

An exercise rise in systolic blood pressure (over 200 mm Hg) has been used as a reason to terminate exercise in some centers. Sheps and coworkers found that when diastolic pressure increased with exercise, it identified a subset of patients with a higher probability of coronary artery disease.

Hypotensive Response

Systolic hypotension during exercise occurs under a number of circumstances that must be clearly identified in orders to assess its significance.

Many normal persons as well as those with cardiac pathology extend exercise beyond their aerobic threshold. At this point which is usually around 60 per cent or more of their maximum capacity, they have a more rapid increase in heart rate and ventilation and the systolic blood pressure levels off and then begins to fall because of increasing acidosis. When exercise is stopped, this decrease will rapidly abate and the systolic pressure will rebound to a point considerably greater than that recorded at the end of exercise.
