Left ventricular hypertrophy and myocardial ischemia in systemic hypertension

Considerable attention has properly been focused in recent years on electrocardiographic abnormalities in patients with essential hypertension. It has been well established that both voltage evidence of left ventricular (LV) hypertrophy and LV hypertrophy and strain are ominous risk factors. A better understanding of the strain pattern in patients with LV hypertrophy has arisen from experimental animal studies showing how an increase in cardiac mass can lead to myocardial ischemia and from clinical studies showing that the patient with LV hypertrophy and strain is at risk from myocardial ischemia as a consequence of both associated coronary artery disease and increased LV mass. All the clinical syndromes associated with myocardial ischemia are increased in patients with LV hypertrophy and therefore earlier recognition of both cardiac involvement and myocardial ischemia is likely to improve survival in this particularly high-risk group of patients.
