Table 1 Clinical characteristics of the studied groups: patients with MI aged < 50 years (MI < 50), patients with MI aged ≥50 years (MI ≥ 50) and young people without history of MI/CAD aged < 50 years (no-MI < 50); ns – not significant, a - data for TG and glucose showed as median and 25-75th quartile (variables with non-normal distribution)

From: Younger age of patients with myocardial infarction is associated with a higher number of relatives with a history of premature atherosclerosis
