Document Summary
Ischemia/angina usually occurs if there is a minimum of a 70% blockage in one or multiple coronary arteries. Exercise may be inappropriate for patients who get angina at < Goal of exercise should be to increase the anginal and ischemic thresholds. Patients should be taught to recognize the symptoms of angina and report them immediately. Exercise should be stopped if patient"s angina is a 3 or 4 on an angina scale. Prolonged warm-up and cool-down (> 10 mins. ) may be recommended for some patients to prevent early onset of angina or ischemia. Upper body exercises may bring on angina more readily than lower body exercises. Patients who get angina should avoid cold weather and should carry nitroglycerin if it has been prescribed to them. Some physicians recommend that nitroglycerin be taken prophylactically (before exercise) Staff should be well aware of how to emergently handle a patient who gets angina.
