动态心电图监测变异型心绞痛发作的临床价值

变异型心绞痛比稳定型心绞痛少见．容易发展为急性心肌梗死(AMI)并室性心动过速或室颤引起猝死。但心电图表现多为正常。我们回顾本院2000年3月～2002年12月门诊及住院100例变异型心绞痛患者,在心电图检查正常的情况下．经24h动态心电图(DCG)监测发现100例患者均发生不同类型的心律失常、心肌缺血、心肌损伤等。     

Continuous electrocardiographic recording in Prinzmetal's variant angina pectoris: A report of four cases

Four patients with Prinzmetal''s variant angina pectoris were subjected to continuous electrocardiographic recording. In three of them several episodes of ST segment elevation unaccompanied by pain were recorded. In one patient, identical electrocardiographic alterations were observed both in presence or in absence of pain, while in the others a good correlation was evident between pain and severity of the electrocardiographic abnormalities. In two patients transmural myocardial infarction complicated the course of the angina. In contrast to the classical findings, in these patients the attacks of chest pain did not cease after the infarction, but became more frequent and severe. The electrocardiographic alterations of the anginal episodes occurred in the same myocardial areas involved by the infarction, so that a reversible superposition of electrocardiographic signs of acute ischaemia on those of recent necrosis was observed.Continuous electrocardiographic recording provided the best means of investigation of these patients with the variant form of angina pectoris.

Clinical effects of nitrendipine on variant angina pectoris

The clinical effects of nitrendipine, a new calcium antagonist, were investigated in a single-blind test on 21 patients with variant angina pectoris. The efficacy of the drug was evaluated on the basis of frequency of anginal attacks and Holter electrocardiographic findings during different treatment periods at doses of 10 mg once a day (period I) and 20 mg once a day (period II). The number of anginal attacks decreased significantly from a pretreatment level of 2.1 +/- 0.3 per day to 0.7 +/- 0.2 per day in treatment period I and 0.3 +/- 0.1 per day in treatment period II (p less than 0.01, p less than 0.001, respectively). The consumption of sublingual nitroglycerin tablets decreased significantly in both treatment periods in comparison with the observation period before treatment (p less than 0.01, p less than 0.001, respectively). In 20 patients with continuous ECG monitoring, the frequency of ST-segment elevation was 4.5 +/- 1.0 per day during the pretreatment period; it decreased significantly to 0.9 +/- 0.6 per day in treatment period I and 0.5 +/- 0.3 per day in treatment period II (p less than 0.01, p less than 0.001, respectively). The duration and the maximum magnitude of ST-segment elevation also improved significantly in both treatment periods. These results demonstrate the efficacy of nitrendipine in the treatment of variant angina at a single daily dose of 10 mg.
