Do extremely old persons have a genetically favourable profile which has protected them from cardiovascular death? We have tried to answer this question by measuring DNA polymorphisms of selected cardiovascular risk indicators [factor VII, FVII (R/Q353, intron 7 (37bp)n, and -323ins10), beta fibrinogen (-455G/A), plasminogen activator inhibitor type 1, PAI-1 (-675(4G/5G)), tissue plasminogen activator, t-PA (intron 8 ins311), platelet receptor glycoprotein IIb/IIIa, GPIIb/IIIa (L/P33), prothrombin (20210G/A), methylene tetrahydrofolate reductase, MTHFR (A/V114), angiotensin converting enzyme, ACE (intron 16 ins287), and angiotensinogen (M/T235)]. Blood was collected from 187 unselected Danish centenarians, and 201 healthy Danish blood donors, aged 20-64 years (mean age 42 years). Genomic DNA was amplified using PCR and the genotype was determined by RFLP methods or allele-specific amplification followed by agarose gel electrophoresis. The frequencies of the high-risk alleles in centenarians were: for FVII R/Q353 0.91; for FVII intron 7 (37bp)n 0.67; for FVII-323 ins10 0.90; for fibrinogen 0.16; for PAI-1 0.52; for t-PA 0.59; for GPIIb/IIIa 0.16; for prothrombin 0.008; for MTHFR 0.33; for ACE 0.52; and for angiotensinogen 0.36. Comparable frequencies were observed in the blood donors. Subgroup analysis of men and women separately gave similar results. The genotype frequencies in the centenarians and the blood donors were similar for all polymorphisms, and this study suggests that common variations in genes associated with cardiovascular risk do not contribute significantly to longevity.
