    Diabetic patients exhibit altered cardiovascular responses during exercise, including lower maximum heart rates and increased diastolic blood pressure, particularly in males. These findings suggest potential cardiovascular risks in asymptomatic diabetes.

    Area of Science:

    • Cardiology
    • Endocrinology
    • Exercise Physiology

    Background:

    • Cardiovascular disease is a major complication in diabetic patients.
    • Understanding exercise response is crucial for managing diabetes and preventing complications.

    Purpose of the Study:

    • To investigate the cardiovascular response to submaximal bicycle exercise in asymptomatic diabetic patients compared to healthy controls.
    • To identify potential differences in heart rate, blood pressure, and electrocardiographic changes during and after exercise.

    Main Methods:

    • A group of 19 asymptomatic diabetic patients (18-39 years) and 18 age-matched healthy controls underwent submaximal bicycle exercise testing.
    • Cardiovascular parameters including heart rate, systolic and diastolic blood pressure, and electrocardiogram (ECG) were monitored.

    Main Results:

    • Diabetic patients achieved a significantly lower maximum heart rate (159.4 bpm) than controls (175.9 bpm).
    • Diabetic males reached maximum heart rate at a lower workload and exhibited a greater increase in diastolic blood pressure during exercise and post-exercise compared to healthy males.
    • Elevated diastolic blood pressure post-exercise was noted in older diabetics.

    Conclusions:

    • Asymptomatic diabetic patients demonstrate impaired cardiovascular adaptation to exercise.
    • Diabetic males show a more pronounced hypertensive response to exercise.
    • These findings highlight the importance of cardiovascular monitoring in diabetic individuals, even in the absence of symptoms.
