Abstract
Aims:
Since desmin expression is diminished in vascular smooth muscle cells during reparative processes, we wanted to study whether a common intragenic single nucleotide polymorphism at nucleotide position 828 (rs1058261) of the DES gene associates with hypertension, cerebrovascular complications, and all cardiovascular events in the Tampere adult population cardiovascular risk (TAMRISK) study.
Materials and Methods:
A Finnish periodic health examination cohort of 336 subjects with diagnosed hypertension and 473 controls were analyzed. Samples were genotyped for polymorphism using TaqMan techniques. Prevalence of ischemic heart diseases, incidence of cerebrovascular diseases, and transient cerebral ischemic attacks (TIAs) were obtained by self-report and the National Hospital Discharge Registry (HILMO).
Results:
There was no association of any of the rs1058261 genotypes with hypertension at the age of 50. When the subjects were followed to the age of 60, after adjustment for gender and body mass index, subjects with the genotype CC had higher incidence of cerebrovascular events (cerebrovascular diseases and TIA) (4.1%) compared with the T allele (1.6%) (p = 0.046). In addition, those with CC genotype had a higher incidence of all combined cardiovascular events (12.8%) compared with subjects with the T allele (8.5%) (p = 0.028).
Conclusions:
Our findings suggest that variations in the DES gene may be involved in cardiovascular disease.
