  • Title: Further studies on the effect of meals on electrocardiographic pattern in patients with chronic ischaemic heart disease (angima pectoris) and normal electrocardiogram at rest.
    Author: Krupa W.
    Journal: Cor Vasa; 1977; 19(6):437-43. PubMed ID: 610995.
    Abstract:
    The study included 380 subjects divided into 3 groups. Group I comprised 148 patients with angina pectoris and normal resting ECG. Group II included 172 patients with angina pectoris and ECG changes (52 with changes of the ST-T at rest, 120 patients after myocardial infarction). Group III [control] comprised 60 young healthy volunteers aged 21--24 years. In all subjects the ECG was recorded in the morning before breakfast, and then 30 and 60 min. after breakfast. On the following day, Master's test I was performed in group I and III and when its result was negative, Master's test II was carried out. In patients of group I, ST-T changes developed after meals in 113 cases (76.4%) and after Master's tests in 118 cases [79.7%]. In group II, ST-T changes became more intense in 97 [56.3%]. In the control group, ECG changes developed after meals in one case [1.6%] and after Master's tests in two [3.2%]. It is concluded that ECG examination after meals may be a valuable diagnositc test of ischaemic heart disease in patients with normal resting ECG in the period without anginal attacks when contraindications to Master's tests are present.
