In isolated systolic high blood pressure (isolated systolic hypertension, or ISH), systolic blood pressure is elevated (130 mm Hg or higher), but diastolic blood pressure stays below 80 mm Hg. This type of high blood pressure is more common in older adults, especially older women. In fact, the majority of people older than 60 who have hypertension have isolated systolic hypertension.
The results, which were published in the Journal of Human Hypertension, showed that those with higher cholesterol levels had significantly higher blood pressure levels during exercise than those with lower cholesterol levels. The researchers concluded that even mildly increased cholesterol levels could influence blood pressure. They added that cholesterol seems to mess up how blood vessels contract and release, which can also affect the pressure needed to push blood through them.
To learn more about isolated systolic hypertension in young adults, researchers analyzed data from the Chicago Heart Association Detection Project in Industry Study, which tracked the health of more than 25,000 young adults for 30 years. After comparing the blood pressure and health outcomes of participants, researchers found that among women, isolated systolic hypertension more than doubled risk of death and increased risk of heart disease by 55%. In men, isolated systolic hypertension increased risk of heart disease by 23% and heart-related death by 28%. Among both men and women, isolated systolic hypertension increased heart risks just as much or more than having higher than normal overall blood pressure.
Instead of an arbitrary goal to “lose weight,” talk with your doctor about a healthy weight for you. The Centers for Disease Control and Prevention (CDC) recommends a weight loss goal of one to two pounds a week. That means starting off eating 500 calories less per day than what you normally eat. Then decide on what physical activity you can start in order to reach that goal. If exercising five nights a week is too hard to work into your schedule, aim for one more night than what you’re doing right now. When that fits comfortably into your schedule, add another night.
