Top 5 Causes Of Diabetic Cardiomyopathy

Diabetic cardiomyopathy is a medical condition associated with the heart muscle disorder in diabetic people. It disables the heart to circulate blood effectively throughout the body. This state is also known as the heart failure in which fluids accumulate in the lungs or legs. Diabetic cardiomyopathy is known to affect the lower chamber of the heart and tremendously hinder the quality of life.

This medical condition also leads to the inability of the heart to pump effectively. The diabetic cardiomyopathy is reported to increase with the rise in the number of cases of diabetes. It is very important to understand the causes of diabetic cardiomyopathy to ascertain what leads to this chronic ailment of the heart in diabetic people.

Main Causes of Diabetic Cardiomyopathy

Altered Usage of Fuel

A healthy heart derives most part of the energy from the fatty acids and some part from glucose. However, in case of death of some tissues or during failure of the heart, the usage of cardiac glucose increases and the fat consumption reduces. In case of diabetic cardiomyopathy, heart uses more fat than glucose in comparison with healthy hearts.

This is an opposite situation of how hearts work towards modifying the fuel usage during the heart failure or infarction. In diabetes, the cardiac glucose metabolism reduces due to lack of sufficient insulin, insulin resistance or abundance of fatty acids.


Obesity is one of the main causes of diabetic cardiomyopathy. This condition may be a result of an unhealthy lifestyle and lack of exercise.

If this condition is not treated and brought under control, then it may affect your heart and in worst case may lead to heart failure. If you notice that you are gaining weight uncontrollably, then it is wise to check with your doctor, for it may be a potent cause of diabetic cardiomyopathy.


Hypertension is a term that is used to explain high blood pressure. If the reading of the blood pressure is higher than 120 over 80, then this reading is considered to denote hypertension. A lot of people may experience high blood pressure owing to different reasons such as stress or depression. When diabetes combines with hypertension, it may cause diabetic cardiomyopathy and adversely affect your heart. If you notice that you are facing problems due to high blood pressure, then it is recommended that you check with your heart specialist.

Autonomic Neuropathy

Autonomic neuropathy is one of the main causes of diabetic cardiomyopathy. Though the heart is capable of functioning without the help of the nervous system, it is innervated with autonomic nerves.

This helps to regulate the heart beat as per the demands, before any hormonal release. In diabetic cardiomyopathy, the autonomic innervations of the myocardium are modified, which contributes to the myocardial dysfunction.


Microangiopathy is one of the major causes of diabetic cardiomyopathy. It is characterized as the endothelial fibrosis in the heart’s coronary microvasculature. The improper functioning of the endothelium leads to damaged reserve of the myocardial blood flow. It is reported that almost 50 percent of the patients suffering from diabetic cardiomyopathy reports pathologic proof for microangiopathy.
