Association of Chromosome 9p21 With Subsequent Coronary Heart Disease Events

Abstract

Background: Genetic variation at chromosome 9p21 is a recognized risk factor for coronary heart disease (CHD). However, its effect on disease progression and subsequent events is unclear, raising questions about its value for stratification of residual risk.

Methods: A variant at chromosome 9p21 (rs1333049) was tested for association with subsequent events during follow-up in 103 357 Europeans with established CHD at baseline from the GENIUS-CHD (Genetics of Subsequent Coronary Heart Disease) Consortium (73.1% male, mean age 62.9 years). The primary outcome, subsequent CHD death or myocardial infarction (CHD death/myocardial infarction), occurred in 13 040 of the 93 115 participants with available outcome data. Effect estimates were compared with case/control risk obtained from the CARDIoGRAMplusC4D consortium (Coronary Artery Disease Genome-wide Replication and Meta-analysis [CARDIoGRAM] plus The Coronary Artery Disease [C4D] Genetics) including 47 222 CHD cases and 122 264 controls free of CHD.

Results: Meta-analyses revealed no significant association between chromosome 9p21 and the primary outcome of CHD death/myocardial infarction among those with established CHD at baseline (GENIUS-CHD odds ratio, 1.02; 95% CI, 0.99-1.05). This contrasted with a strong association in CARDIoGRAMPlusC4D odds ratio 1.20; 95% CI, 1.18-1.22; P for interaction <0.001 compared with the GENIUS-CHD estimate. Similarly, no clear associations were identified for additional subsequent outcomes, including all-cause death, although we found a modest positive association between chromosome 9p21 and subsequent revascularization (odds ratio, 1.07; 95% CI, 1.04-1.09).

Conclusions: In contrast to studies comparing individuals with CHD to disease-free controls, we found no clear association between genetic variation at chromosome 9p21 and risk of subsequent acute CHD events when all individuals had CHD at baseline. However, the association with subsequent revascularization may support the postulated mechanism of chromosome 9p21 for promoting atheroma development.

Association between chromosome 9p21 and subsequent coronary heart disease (CHD) events in all participants with baseline CHD (GENIUS-CHD [Genetics of Subsequent Coronary Heart Disease]) compared with association in CHD cases and CHD-free controls (CARDIoGRAMPlusC4D). For the CARDIoGRAMPlusC4D consortium (Coronary Artery Disease Genome wide Replication and Meta-analysis [CARDIoGRAM] plus The Coronary Artery Disease [C4D] Genetics) meta-analysis estimate, 6 studies (LURIC, LIFE-Heart [The Leipzig Heart Study], GoDARTS [Genetics of Diabetes Audit and Research in Tayside Scotland], OHGS [Ottawa Heart Genomics Study], PROSPER [Prospective Study of Pravastatin in the Elderly at Risk], WTCCC [Welcome Trust Case Control Consortium]) were excluded as they were also included in GENIUS-CHD. Estimates for GENIUS-CHD are also presented by subtype of CHD at baseline, including acute coronary syndrome (ACS), stable coronary artery disease (CAD) without prior myocardial infarction (MI; CAD/no MI), and stable CAD with prior MI (CAD/MI). All estimates were adjusted for age and sex.

Association between chromosome 9p21 and secondary outcomes in participants with baseline CHD, within GENIUS-CHD (Genetics of Subsequent Coronary Heart Disease). All meta-analysis estimates were adjusted for age and sex. CHD indicates coronary heart disease; CVD, cardiovascular disease; MI, myocardial infarction; and OR, odds ratio.
