No—among people with diabetes, both high readings and a top number below 100 mm Hg were linked to a higher risk of sudden cardiac arrest. Sudden cardiac arrest means the heart suddenly stops pumping blood. The study used South Korean national health insurance data from 4,593,706 people. All had a national health screening in 2012. Researchers compared blood pressure and cardiac arrest risk across three groups. There were 3,097,423 people without diabetes, 1,034,563 with raised blood sugar below the diabetes range, and 461,720 with diabetes. For Blood Pressure — Systolic, the top number in a reading, the pattern depended on diabetes status. People with both high blood pressure and diabetes had the highest overall risk. Yet the difference in risk linked to blood pressure was larger in people without diabetes. Among people with diabetes, risk was higher at both ends of the range. High readings were linked to greater risk, but so were readings below 100 mm Hg. The source does not give the size of that added risk. It also does not establish one best target for everyone. These were links found in health records, not proof that low readings caused cardiac arrest. For BioSocial members, the takeaway is that lower is not always better. Tracking your usual range can offer more context than celebrating your lowest reading. When comparing notes with the community, diabetes status matters too. A similar number may not carry the same meaning for everyone. This study supports a more thoughtful conversation about patterns, rather than a race toward lower numbers. What patterns have you noticed in your readings over time, especially if you live with diabetes?
