Prevalence, predisposing factors, and prognosis of clinically unrecognized myocardial in-farction in the elderly. If You Have High Blood Pressure, Have It in Tokyo Men in the U.S. with high blood pressure are more likely to die from a heart attack than their middle-aged peers in Tokyo, a new study has found. Although genetics may play a role, researchers believe that differences in diet have the greatest impact. Researchers followed 12,031 men in six geographic areas and found that for each ten-point increase in systolic blood pressure, risk of death rose 28 percent. However, men with equal blood pressure rates were more likely to die if they lived in Northern Europe or the U.S. as opposed to Japan or the Mediterranean.
Researchers note that diets in the latter group contained less meat and dairy products.
The relationship between blood pressure and mortality due to coronary heart disease among men in different parts of the world. Seven countries study research group. While the dairy industry has claimed that calcium lowers blood pressure, its effect, if any, is trivial, as was again confirmed by a new study. For six months, University of South Carolina researchers followed 193 men and women, one group taking a placebo and the other taking calcium carbonate tablets twice daily. Blood pressure was measured several times throughout the trial and ultimately showed calcium to have no significant effect on blood pressure.
