The authors reviewed some of the most relevant studies dedicated to the assessment of the effects of the antihypertensive drugs on the stress-induced cardiovascular changes. The rises in both blood pressure and heart rate turned out not to be significantly altered by calcium channel blockers, ACE inhibitors, moxonidine, nor beta-blockers, whereas they seemed to be slightly blunted by alpha-blocking drugs. However, since baseline blood pressure was significantly lower in treated hypertensives than in placebo-given patients, all antihypertensive drugs eventually resulted in a lower blood pressure level during stress, as compared with untreated patients. Regarding white coat effect, which has to be considered as a very particular stress, it appeared to be lowered to the same extent by placebo and antihypertensive drugs; moreover, its changes were not associated with any clinical beneficial effect.
