France: An increase in coronary artery calcium score (CACS) in asymptomatic diabetes patients is strongly associated with an increased risk of mortality and/or fatal and non-fatal cardiovascular events, says a recent study in the Journal of Diabetes and its Complications. This implies that CACS can help to make a decision to start preventive drug therapy in diabetics. 

Diabetes' pharmacological management is based mostly on the assessment of cardiovascular risk. For this purpose, CACS is proposed with a soft (class IIb) recommendation, as its prognostic implication in different subsets requires further evidence. Thus, Mamadou Adama Sow, University of Limoges, Limoges, France, and colleagues carried out a systematic review and meta-analysis to address the high CACS prevalence, its prognostic value, and determinants in diabetes, with a special focus on different sex and ethnic groups.

For this purpose, the researchers conducted a systematic review of the published literature in several databases between 01/2000 and 01/2021. Original studies were included if they presented data on the determinants, prevalence, and prognosis of high CACS in diabetes patients without known cardiovascular disease. 

Pooled odds ratios (OR) for CACS determinants and Relative Risk (RR) for CACS prognostic values were calculated on all-cause mortality and/or fatal and non-fatal CV events in different categories using random-effects models. A total of 23 studies consisting of 20,999 patients were included. 

The findings of the study were as follows:

  • Female sex and black ethnicity presented the lowest prevalence of CACS>0.
  • Age, male sex, non-black ethnicity, and diabetes duration were identified as risk factors for high CACS.
  • Among the 10 studies (n = 110,396 person-years) with prognostic data, the pooled RR for the occurrence of all-cause death and/or cardiovascular events were 4.03, 5.87 and 9.04 respectively for CACS>0 vs. CACS = 0, CACS≥100 vs. CACS<10 and CACS≥400 vs. CACS<10. For similar CACS, these RR were greater in women than in men.

"Our meta-analysis shows that in asymptomatic patients with diabetes the increase in CACS is strongly associated with an increased risk for all-cause mortality and/or fatal and non-fatal CV events," the authors concluded.
