...severe heart attack at the age of 46, in mid-1955, Johnson subjected himself to 13 years of the most grueling, tension-ridden work. Yet during that period, his health seemed generally good. Cardiologists reviewing Johnson's medical history see evidence that for him, as for many another cardiac patient, frustration or the slower pace of retirement can be more lethal than the strain of a highly active life...
...Just how much exercise is right for the cardiac patient? Faced with this question, doctors have searched for easy means for the patient to determine when his heart has exceeded a safe rate. A team of German researchers now appears to have found one. Physicist Hans Stephan and Drs. Hans Stoboy and Adalbert Schaede have developed a device called a Cardiomed that monitors the working heart and tells when it is not beating at the proper rate. Not much larger than a billfold, the battery-operated gadget checks on the heart through electrodes stuck on the chest. It emits...
...different interests and career ambitions, the two earnest high school students also have something in common: a life-threatening genetic defect. Both suffer from Cooley's anemia (thalassemia major), a hereditary blood disease resulting in deficient synthesis of hemoglobin, the oxygen-carrying component of blood. Their condition causes cardiac and other complications that kill most of its victims in their teen-age years. The pale, often undersized youngsters may have bone deformities and enlarged spleens and livers; they tire easily and frequently miss school...
Helpful Guilt. Some post-cardiac patients have followed the lead of SPORTS ILLUSTRATED Senior Editor Tex Maule and jogged their way back to health on their own. But as Maule acknowledges in his recently published Running Scarred (Saturday Review Press; $6.95), unsupervised exercise is dangerous. For one thing, few doctors -or cardiac patients-are as familiar with the physiology of exercise as the Y's trained instructors. For another, most people need constant encouragement to remain with any calisthenics program. Says John Bazikian, 68, a retired New Yorker who suffered from mild angina pectoris three years ago: "With...
Berry hopes his precautions will make medication unnecessary. "Prescribing a cardiac drug on the lunar surface from 250,000 miles away would be a first that I would prefer to avoid," he says. But Berry hopes to score a first by learning-with greater precision than last time-how much potassium is lost by astronauts traveling and working in space. To do this, he determined the preflight potassium levels of each of the Apollo 16 astronauts. He has also asked them to bring back urine samples from a test to be conducted during the flight, and is confident that...
