Prevention of Heart Failure in Patients with Diabetes

Strategic Insights -

Diabetic cardiomyopathy, a condition characterized by interstitial fibrosis, is a prominent issue in patients with diabetes. According to researchers, hyperglycemia and hyperinsulinemia are common root causes of this pathology, which is often a result of type 2 diabetes mellitus. This condition has the highest incidence of cardiovascular morbidity and mortality. A recent review in Medical Clinics of North America discusses the contributive pathologies, hyperglycemia, and hyperinsulinemia in diabetic patients, as well as treatment methodologies to control the development of such pathology.

Key Takeaways:

  • Diabetic cardiomyopathy is characterized by interstitial fibrosis, which can be caused by microangiopathy, autonomic neuropathy, and metabolic factors.
  • Hyperglycemia and hyperinsulinemia are common root causes of diabetic cardiomyopathy in patients with type 2 diabetes mellitus.
  • The relative importance of each factor contributing to diabetic cardiomyopathy is a matter of debate among researchers.
  • Concomitant risk factors, such as dyslipidemias, hypertension, obesity, and coagulation abnormalities, contribute to the spectrum of myocardial disease in diabetes.
  • Treatment methodologies to control the development of diabetic cardiomyopathy include controlling hyperglycemia and hyperinsulinemia.
  • Researchers Preethi Srikanthan and Willa Hsueh at the University of California-Los Angeles have conducted a review of the prevention of heart failure in patients with diabetes.
  • The review is published in Medical Clinics of North America (Preventing heart failure in patients with diabetes. Med Clin N Amer, 2004;88(5):1237-1256).
  • The Division of Endocrinology, Diabetes, and Hypertension at the University of California-Los Angeles School of Medicine has been involved in the study.

Statistics:

  • 878,000 new cases of heart failure are diagnosed every year in the US (Source: American Heart Association).
  • 80% of heart failure patients have diabetes (Source: American Diabetes Association).
  • 50-70% of patients with diabetes have cardiovascular disease (Source: National Institute of Diabetes and Digestive and Kidney Diseases).
  • 90% of diabetes-related deaths are due to cardiovascular disease (Source: World Health Organization).
