[Heart failure. Cardiovascular autonomic neuropathy in patients with diabetes mellitus]

Area of Science:

• Cardiology
• Endocrinology
• Autonomic Nervous System Research

Context:

• Diabetes mellitus significantly reduces life expectancy.
• Cardiac autonomic neuropathy (CAN) is a major contributing factor, alongside coronary heart disease and diabetic cardiomyopathy.
• CAN impairs cardiovascular autonomic control, leading to serious complications.

Purpose:

• To highlight the prevalence and impact of cardiac autonomic neuropathy in diabetes mellitus.
• To emphasize the symptoms and diagnostic methods for CAN.
• To underscore the importance of early detection and intervention for CAN in diabetic patients.

Summary:

• Cardiac autonomic neuropathy (CAN) is a common complication in diabetes mellitus, affecting cardiovascular control.
• Symptoms include reduced heart rate variability, fixed heart rate, symptomatic hypotension, reduced ejection fraction, arrhythmias, and sudden cardiac death.
• Prevalence increases with age, affecting approximately 38-44% of diabetic patients aged 40-70.

Impact:

• Early identification of CAN through cardiovascular autonomic testing is vital for initiating prompt therapy.
• Managing CAN can potentially improve outcomes and mitigate the reduced life expectancy associated with diabetes mellitus.
• This research underscores the need for integrated cardiovascular monitoring in diabetes care.
