...case some of the plaques start to shrink, almost imperceptibly at first, as the fatty material in its core migrates back into the bloodstream. Blood begins flowing more smoothly through the rejuvenated artery, and two years later, only 50% of the passage is blocked. The seemingly inexorable advance of cardiovascular disease has been reversed, and as the plaque continues to shrink, the risk of a heart attack has largely passed...
Each year Americans consume millions of pounds of French fries at fast-food outlets. While the potatoes are innocent enough, the leading chains have traditionally deep fried them in oil that contains beef tallow. That substance contains cholesterol and saturated fat, both considered archenemies of the cardiovascular system. Phil Sokolof of Omaha, a wealthy businessman and health-food zealot, has been leading a public campaign to urge the franchises to stop using saturated fat to cook their fries...
...maximum force with which the heart expels blood; the 90 indicates diastolic pressure, the strength of blood flow between beats.) But in this study of nearly 1,000 patients, the researchers found that even people with a mean blood pressure of 130/94 already showed the warning signs of cardiovascular problems. The muscle in their hearts had become less elastic, and failed to relax completely between contractions...
Attempts to reach Sakharov's home in Moscow by telephone were unsuccessful. Sakharov had suffered from angina, but during a visit to the United States in December 1988, doctors at Massachusetts General Hospital determined he did not need heart surgery or a pacemaker after cardiovascular tests...
While this and earlier studies agree on the health benefits of regular, moderate exercise, no one is sure of the physiological mechanisms involved. It may be that exercise increases coronary blood flow, decreases clotting or both, which would limit the blood-vessel blockages that cause cardiovascular problems. And some scientists speculate that exercise increases bowel motility, a factor in avoiding colon cancer. Those questions may be answered in part by the next phase of the investigation, which is expected to include more than 40,000 people. Such speculations are literally academic, though. For the average man or woman, the message...
