Heart and blood vessel disease is a known complication of Type 2 diabetes. Scientists at the Shanghai Institute for Endocrine and Metabolic Diseases conducted a study to learn whether prediabetes could also put patients in danger.
Their study, reported on in the medical journal Hypertension in February 2015, included 1609 participants diagnosed with prediabetes who lived in Shanghai, southern China. By the end of 12 years, 10.1 percent of the study participants were diagnosed with Type 2 diabetes. Prediabetics with normal blood pressure readings did not show a high risk of heart and blood vessel disease, but prediabetics with high blood pressure readings did.
The prediabetic participants with high blood pressure readings had more than twice the risk of heart and blood vessel disease as the healthy participants, and diabetics with high blood pressure readings had more than three times the risk.
