Currently, echocardiography is the most accepted tool for diagnosing t
he left ventricular hypertrophy that characterizes hypertensive heart
disease; electrocardiography is not adequately sensitive. The symptoms
and signs of coronary artery disease (CAD) and of hypertensive heart
disease are similar and include angina, myocardial infarction, systoli
c and diastolic heart failure, atrial fibrillation, ventricular ectopy
, and sudden death. Thallium stress testing is useful for excluding si
gnificant CAD; a positive test requires cardiac catheterization to eli
minate large-vessel disease as the cause of myocardial ischemia. Regre
ssion of left ventricular hypertrophy is a treatment goal.
