Radiation exposure in interventional cardiology: a narrative review of health effects and novel approaches to ensure radiation safety

In plain language

This review of 35 studies summarizes reported links between occupational radiation and cataract, chromosomal damage, cancer, cardiovascular and orthopedic problems in cath lab staff, and outlines shielding, dose-reduction, training and newer protection systems. Evidence is largely observational.

What it found

A cited meta-analysis found posterior lens opacity significantly more common in interventional cardiologists than controls, with no difference for cortical or nuclear opacity.
Key figures: Relative risk (RR) =3.21; 95% confidence interval (CI): 2.14, 4.83; 8 studies, 2,559 subjects
Reported case series of brain tumors in interventional physicians, many left-sided, though risk cannot be reliably quantified.
Key figures: six interventional cardiologists and three interventional radiologists
In a survey of 615 participants, orthopedic problems were common and associated with years of exposure; cancer prevalence trended higher in women.
Key figures: 19.5% orthopedic problems (P=0.001 with years); cancer 4.4% vs. 1.8%, P=0.07
Radiology and cardiology workers showed higher chromosomal aberration and micronucleus frequencies than matched controls.
Key figures: 30 radiology, 30 cardiology workers, 27 controls
A cited meta-analysis linked radiation exposure to higher dementia risk per 100 mSv.
Key figures: RR 1.11 (95% CI: 1.04, 1.18; P=0.001)

Limits to keep in mind

Narrative review of 35 studies with qualitative synthesis and no pooled analysis; much cited evidence comes from case series, cross-sectional biomarker studies, self-report surveys and non-medical worker cohorts, so causal links are not established.
