[Early coronary heart disease together with tyoe II diabetes mellitus in persons of Hindustani origin].
OBJECTIVE
To investigate the association between early coronary heart disease and non insulin dependent diabetes mellitus in South Asian patients in the Netherlands, a homogeneous population which descends from Indian immigrants to Surinam in the late nineteenth century.


METHODS
Case control study.


METHODS
University hospital Leiden.


METHODS
South Asian patients (n = 38) and control patients (n = 76) were identified in an automated data base comprising all patients who had aortocoronary surgery in the period January 1st 1990 to January 1st 1993. Control patients were from the general population and matched for calendar time. Patients' characteristics such as the onset of coronary heart disease and the presence of non insulin dependent diabetes mellitus were obtained from the medical records at the time of surgery.


RESULTS
The onset of coronary heart disease in South Asian patients occurred about eight years earlier than in control patients (49.8 versus 58.2 years; 95% confidence interval of the difference: 4.3-12.5). Non insulin dependent diabetes mellitus was about four times more frequent in South Asian patients (50% versus 13%; 19-54). This difference was the same after correction for differences in sex, age, and body mass index.


CONCLUSIONS
Diabetes mellitus caused by insulin resistance significantly contributes to early coronary heart disease in South Asian immigrant patients, in accordance with the literature on the present population of India. These findings strengthen the belief that genetic factor are important in the development of insulin resistance and atherosclerosis.
