Highlights
- •Adult height is inversely associated with the risk of coronary artery disease (CAD).
- •We tested the association with the extent of CAD on angiography.
- •We found that shorter height is associated with greater angiographic extent of CAD.
Abstract
Background and aims
Shorter stature is an established risk factor for coronary artery disease (CAD), but
less is known about its association with extent of the disease.
Methods
We assessed the relationship between self-reported height and angiographic findings
in 7706 men and 3572 women identified from a nationwide coronary angiography registry
in Iceland.
Results
After adjustment for traditional cardiovascular risk factors, a standard deviation
decrease in height associated with a greater likelihood of significant CAD (defined
as ≥50% luminal diameter stenosis) both in men (adjusted odds ratio [ORadj]: 1.24, 95% confidence interval [CI]: 1.18, 1.31; p = 3.2 × 10−16) and women (ORadj = 1.10, 95% CI: 1.02, 1.18; p = 0.012). In partial proportional odds logistic regression models, a standard deviation
decrease in height was associated with higher odds of having greater extent of CAD
in men (ORadj = 1.19, 95% CI: 1.15, 1.25; p = 1.5 × 10−16) and women (ORadj = 1.09, 95% CI: 1.02, 1.16; p = 0.014). When limited to patients with significant CAD, the association was statistically
significant in men (ORadj = 1.08, 95% CI: 1.03, 1.14; p = 0.0022) but not in women (p = 0.56).
Conclusions
Our findings show that shorter stature is associated with greater extent of coronary
atherosclerosis in a large unselected population of individuals undergoing coronary
angiography. This relationship appears to be sex-dependent, with stronger effects
in men than in women.
