CARDIO inCode® Score is a genetic test for the evaluation of the coronary genetic load based on a Polygenic Risk Score and a further cardiovascular risk assessment (the risk of having a coronary event in the next 10 years).
Genetics make a 50% contribution to the development of cardiovascular events (Zdravkovic et al., 2002; Wienke et al., 2005; Elosua et al., 2009; Roberts R, 2018; O’Sullivan et al, 2022), and there is a direct, linear association between the genetic load and the risk of coronary events (both incident and recurrent) (Lluis-Ganella et al., 2010; Lluis-Ganella et al., 2012; Mega et al, 2015; Natarajan et al., 2017; Rincón et al., 2020; Marston et al., 2020; Damask et al, 2020; Emdin et al., 2020).
A significant proportion of events (up to 60% in the Spanish population) take place in individuals classified in the low and moderate risk groups based on classical cardiovascular risk factors (Marrugat et al., 2011; Iribarren et al., 2016).
The inclusion of the genetic load in the clinical assessment makes it possible to attain a more accurate and reliable overall cardiovascular risk evaluation, and identify those patients at highest risk, for whom to adjust therapy and therapeutic goals to their new cardiovascular risk level.
With CARDIO inCode® Score, 5% of patients in the low-risk group and 14% of those in the moderate-risk group are reclassified to higher risk categories (Iribarren et al., 2016).
Genes/variants analysed and technology
These genetic variants are associated with ischaemic heart disease and are independent of classical cardiovascular risk factors (Lluis-Ganella et al., 2010; Lluis-Ganella et al., 2012). These variants have been identified in Genome-Wide Association studies or GWAs.
- Patients with classical cardiovascular risk factors
- Patients with other risk factors (overweight or obesity, hypertriglyceridaemia, etc.)
- Patients with intermediate/moderate 10-year cardiovascular risk
- Patients with a family history of ischaemic heart disease, especially if in first-degree relatives and/or at young ages
- Siblings of patients with a high coronary genetic load (high genetic risk or in quintile 5)
- As part of a general medical check-up
CARDIO inCode® Score is the only available genetic test for the assessment of cardiovascular risk that measures the patient’s coronary genetic load and integrates it into current clinical risk estimation functions (Framingham, REGICOR, SCORE Low Risk, SCORE High Risk, or Pooled Cohort Equation).
This allows reporting of cardiovascular risk without and with the coronary genetic load, enabling patient’s reclassification into higher risk categories. It also allows for the detection of individuals in the intermediate/moderate risk categories with a high coronary genetic load (in quintile 5) who are not currently reclassified.
In addition, CARDIO inCode® Score is the only test that has been validated in over 75,000 individuals from different population origins (Spanish, European Americans, Latin Americans, African Americans, and Asians).
