ANGINA: CHOOSE YOUR EXERCISE CAREFULLY
Exercise won’t kill you, but choose it wisely. Don’t opt for explosive exercise, such as weightlifting. The action of lifting weights or straining muscles while holding your breath, known as the Valsalva maneuver, is harmful, not beneficial. If you are not a fully trained weightlifter, it can cause a sudden drop in the blood returning from the lower body to the heart. At best it can make you dizzy; at worst it can make you unconscious. If you already have a poor flow of blood through a coronary artery, the Valsalva maneuver can be the final insult, bringing on a heart attack. The same may occur in explosive sports like squash. Golf is more leisurely, and probably better for you.
If you are thinking of taking up a sport, take a few lessons from a professional first. It will give you an idea of how you will like it, and make it much easier to enjoy.
