Vigorous exercise in previously inactive individuals over age 35 carries a high risk of fatal or nonfatal heart attacks or sudden death. Therefore, do not rush to get superfit. Get fit slowly over three to six months, remembering that fitness is a relative term — fit to do what?
In addition, we emphasize that simple exercises such as walking two miles in a half hour or when possible four miles in an hour, climbing stairs, or peddling a statio¬nary bicycle for 15 minutes are excellent, safe exercises. Walking is always helpful and ‘‘never’’ causes a heart attack. It does not increase blood pressure, instead it improves circulation in the legs and may have a favorable influence on blood clotting. Therefore, if you walk, you may win the race.
Exercise has important benefits, but it cannot be expected to halt the progression or complications of coronary artery disease, and attention to aggressive control of known risk factors is necessary. Exercise prescriptions for patients who have heart disease, especially coronary heart disease, are discussed in the chapter Heart Attacks.
