A guide for Gensini Score calculation

We have read with great interest the recent article by Wang et al. [1], in which the researchers investigate the effects of leukocyte telomere length and mitochondrial DNA copy number, alone or in combination, on coronary artery disease (CAD) risk and severity in the Chinese population. As reported by the authors, the angiographic burden of CAD was quantified by the modified Gensini Score.
