Why the study?
Although echocardiographic LV hypertrophy is linked to all-cause and cardiovascular mortality, little was known regarding its association with sudden death.
Does increased left ventricular mass and hypertrophy increase the risk of sudden death in adults >=40 years of age?
Does increased left ventricular mass and hypertrophy increase the risk of sudden death in adults >=40 years of age?
Echocardiographic left ventricular hypertrophy is associated with a more than twofold increased risk of sudden death, independent of known risk factors.
No takes yet. Share an insight, caveat, or question.
May enhance sudden death risk stratification via echo LV mass; leaves open whether LVH regression prevents events.
Haider et al. (1998) studied this question.
