According to The Lancet Diabetes & Endocrinology, the results of the two studies showed that people with prediabetes who were able to bring their blood sugar levels back to normal had significantly lower rates of death from cardiovascular disease and hospitalization due to heart failure.
The scientists followed the participants for 20 to 30 years, comparing those whose prediabetes returned with those whose blood sugar levels remained high. They observed that people with prediabetes whose blood glucose levels returned to normal had a nearly 50 to 60% lower risk of death from cardiovascular disease or hospitalization due to heart failure, and their risk of heart attacks and strokes was also significantly reduced.
The return of prediabetes indicators to normal was determined based on several indicators, including the HbA1c test, which reflects the average blood sugar level over the past two to three months.
The researchers emphasized that a healthy lifestyle is an important factor in itself for preventing cardiovascular disease, but the return of blood sugar levels to their normal values may play a key role in long-term protection of the heart, thus complementing standard preventive measures for preventing cardiovascular disease.
