[Individualising antihypertensive therapy in patients with diabetes. A guideline by the Austrian Diabetes Association (update 2023)]

Hypertension is one of the most important comorbidities of diabetes, contributing significantly to death and leading to macrovascular and microvascular complications. When assessing the medical priorities for patients with diabetes, treating hypertension should be a primary consideration. In the present review practical approaches to hypertension in diabetes, including individualized targets for preventing specific complications are discussed according to current evidence and guidelines. Blood pressure values of about 130/80 mm Hg are associated with the best outcome; most importantly, at least blood pressure values < 140/90 mm Hg should be achieved in most patients. Angiotensin converting enzyme inhibitors or angiotensin receptor blockers should be preferred in patients with diabetes, especially in those who also have albuminuria or coronary artery disease. Most patients with diabetes require combination therapy to achieve blood pressure goals; agents with proven cardiovascular benefit should be used (including, besides angiotensin converting enzyme inhibitors and alternatively angiotensin receptor blockers, dihydropyridin-calcium antagonists and thiazide diuretics), preferable in single-pill combinations. Once the target is achieved, antihypertensive drugs should be continued. Newer antidiabetic medications such as SGLT-2-inhibitors or GLP1-receptor agonists have also antihypertensive effects.

Hypertension is one of the most important comorbidities of diabetes, contributing significantly to death and leads to macrovascular and microvascular complications. When assessing the medical priorities for patients with diabetes, treating hypertension should be a primary consideration. In the present review practical approaches to hypertension in diabetes, including individualized targets for preventing specific complications are discussed according to current studies and guidelines. According to recent studies, blood pressure values of about 130/80 mm Hg are associated with the best outcome. Angiotensin converting enzyme inhibitors and angiotensin receptor blockers are the most effective drugs for treating hypertension in diabetes. Calcium antagonists or diuretics are acceptable as second-line agents. Once the target is achieved, antihypertensive drugs should be continued. Newer antidiabetic medications such as SGLT-2-inhibitors or GLP1-receptor agonists have also antihypertensive effects.

Assessment of dipyridamole stress echocardiography for risk stratification of diabetic patients

BACKGROUND

Despite advances in medical therapy, cardiovascular disease, mainly coronary artery disease (CAD), remains the leading cause of mortality among patients with diabetes mellitus (DM). The objective of the present study was to assess the effectiveness of dipyridamole stress echocardiography in identify diabetic patients at high risk for cardiovascular events.

METHODS

Dipyridamole stress echocardiography was administered to 483 diabetic patients (294 women; mean age 63.41 ± 11.28 years) between July 2006 and December 2012.

RESULTS

Follow-up data were available for 264 patients (163 women; mean age 64.3 ± 10.5 years): 250 with a negative stress echocardiography and 14 with a positive stress echo. During a mean follow-up time of 18 ± 14 months, a cardiovascular event occurred in 18 (6.8%) patients, 12 (4.8%) in patients with a negative stress echo (n = 250) during a mean follow-up period of 20 ± 16 months and 6 (42%) in patients with positive stress echo (n = 14) during a mean follow-up of 13 ± 13 months. The positive and negative predictive values of stress echocardiography were 42% and 96% respectively. The accuracy value was 92%. A Cox regression model showed that CAD (hazard ratio [HR] 5.4, 95% confidence interval [CI] 1.9-15.4; p = 0.002) and positive stress echocardiography (HR 7.1, 95% CI 2.5-20.5; p < 0.001) were significant predictors of cardiovascular events.

CONCLUSIONS

For patients with diabetes, a negative dipyridamole stress echocardiogram predicts favorable outcome during the first year of follow-up. A new stress imaging test should be done after 12 months in diabetic patients.
