...first clue is often the catastrophe itself: a fatal heart attack. But the events that set the stage for disaster, like those preceding an earthquake, have been occurring for years beneath the surface, painless and unnoticed. The culprit is silent ischemia, an intermittent interruption of blood flow to the heart, which kills tens of thousands of seemingly healthy Americans each year. Doctors estimate that the condition, undetected, exists in an additional 3 million to 4 million people known to have heart disease and further increases the likelihood they will suffer a heart attack...
Although silent ischemia was identified nearly two decades ago, the attention it received at last week's annual scientific meeting of the American Heart Association in Dallas reflected a growing awareness that it is a formidable medical problem. Says Cardiologist William Shell, of the University of California, Los Angeles: "It may be silent, but it can be deadly...
...Hopkins team, led by Cardiologist Sidney Gottlieb, examined 103 heartattack patients who seemed to be recovering without complications or pain and found that 30 were having ischemic episodes. One year later nine (30%) of these people had died from heart attacks. Of the 73 without silent ischemia, only eight (11%) had suffered fatal heart attacks. "If you have had a heart attack and you have ischemia," Gottlieb concluded, "you may have a three times greater risk of dying...
...draft. Their language, however, was somewhat different from grandma's. Said Dr. Irwin Gabriel Spiesman of Maywood, Ill., making a clean breast of it to 99 other experts in Atlantic City: "Rapid cooling of most cutaneous surfaces produces a reflex vasoconstriction [tightening of blood vessels] and ischemia [lack of blood] leading to lowered mucous membrane temperature of the upper respiratory tract...
...Thomas Lewis, editor of the English journal, Heart, described experiments into the cause of peripheral neuritis, a disease affecting the nerves, producing intense pain, usually in the extremities. He found the cause was a deficiency of blood in the nerves, a condition known as ischemia...
