Abstract

BACKGROUND:

Cardiovascular risk factors of the diabetic patient should be treated as aggressively as those of the nondiabetic patient who has had a myocardial infarction. beta-Blockers are established to reduce cardiovascular risk in patients with hypertension, coronary heart disease, and heart failure. Despite this benefit of beta-blockers, physicians have been reluctant to use them in patients with diabetes, in whom they are even more effective, because of the negative effects on carbohydrate and lipid metabolism.

OBJECTIVE:

This paper reviews (based on a Medline literature search to December 2004) the relationship between diabetes and cardiovascular risk factors, describes the metabolic consequences of insulin resistance, and discusses the impact of different beta-blockers on the treatment of cardiovascular disease in patients with diabetes.

RESULTS:

There is a large cardioprotective benefit with the use of beta-blockers in patients with diabetes; however, metabolic risks are associated with some beta-blockers. Newer, vasodilating, nonselective beta-blockers do not have the same adverse metabolic consequences observed with earlier beta-blockers. Recent evidence has shown that they have a neutral effect on metabolic parameters and lipid profile. They do not promote insulin resistance and can be used safely in heart failure patients with diabetes.

CONCLUSIONS:

Nonselective vasodilating beta-blockers, such as carvedilol, may be used in patients with cardiovascular disease and diabetes without the same negative metabolic consequences seen with the use of earlier generation beta-blockers.
