title: [Myocardial ischemia detected by Holter monitoring: analysis of therapeutical trials realised in stable angina].
abstract: Silent myocardial ischaemia is the most frequent consequence of coronary artery disease and occurs in almost 70 per cent to 80 per cent of ischaemic episodes. In some studies, it has some predictive value of cardiovascular events either in stable or unstable angina or after myocardial infarction. In this last case, one year mortality is 30 per cent and 11 per cent respectively with and without silent ischaemia that has been recorded on the 8th day after myocardial infarction. This review has focused on controlled studies in patients with angina and Holter recorded ischaemia. Nitrates are very likely to be active substances on Holter recorded angina but no controlled studies have been performed to really demonstrate it. The efficacy of beta-blocking agents is well established with a 60 per cent reduction in the number of ischaemic events and a 80 per cent reduction in total ischaemic duration. Nifedipine efficacy appears lower than that of beta-blockers with an evaluated mean reduction of 39 per cent for the number of events and of 43 per cent for duration of episodes. Diltiazem induces a 48 per cent reduction of both ischaemic parameters. For drug associations, addition of a calcium antagonist to a beta-blocking agent provides only little benefit. The relationship between anti-ischaemic efficacy and long term prevention of cardiovascular events remains to be established for a given anti-ischaemic therapy.
