Hartslag helpt botbreuken en dood voorspellen.*

Uit een ruim 10 jarige studie onder ruim 9.000 vrouwen van 65 en ouder blijkt dat zij, met een hartslag van 80 of meer, 60% meer kans hebben op botbreuken, 40 meer kans op doodgaan en 50% meer kans op een hartziekte..

- How quickly the heart pumps blood may affect the risk of bone fracture and death in elderly women, new research suggests. In a study of more than 9,000 elderly women, those with the fastest resting heart rates--80 or more beats per minute--were 60% more likely to have a hip, pelvis or rib fracture than women with slower tickers. For vertebral fractures, the risk was 90% higher. Women with fast-beating hearts also were 40% more likely to die from any cause and 50% more likely to die from heart disease. Researchers took into account many factors that could have influenced the results, including age, weight, overall health, physical activity and smoking, but these factors did not explain the increased risk of fracture and death. The results "suggest that lowering heart rate may be beneficial in decreasing the risk of osteoporotic fractures and mortality.," An "obvious intervention" for women with a heart rate greater than 80, Kado said, is exercise, which has many health benefits. "However, more investigation is needed to confirm our study findings, especially with regard to fracture risk," she said. The study included 9,702 women aged 65 and older from four different communities in the US. The researchers did not include men or black women, since these groups have low risks of hip fracture. Participants were enrolled in the study between 1986 and 1988, at which time they had their pulse measured after resting for 5 minutes. Participants were followed through March of 1998.
