Arterial hypertension is a major risk factor for myocardial infarction and cardiovascular disease. The presence of left-ventricular hypertrophy in hypertensive patients is associated with a risk of mortality from cardiovascular disease three times greater than the risk with hypertension alone. Hypertension is also associated with an increased mortality and morbidity following myocardial revascularization. This risk is further augmented when left ventricular hypertrophy is present. Calculation of the ventricular mass by echocardiographic methods seems important, particularly in patients with hypertension and poor preoperative left-ventricular function (LVEF < or = 40%), in order to estimate operative risks. In this high-risk group the outcome of surgical revascularization can be improved by utilizing a preoperative intra-aortic balloon support.
