We studied 108 patients who sustained an acute myocardial infarction (AMI) by means of echocardiography, pulsed doppler (PD) and Doppler color flow imaging (CD). We evaluate the presence of mitral ...regurgitation (MR) and it relationship to the site of the AMI and also to the ventricular function. The incidence of MR was 50.92%, (55/108), it was detected in higher percentage when the AMI was inferior (61.8%) than when anterior (39.6%). The correlation with the ejection fraction (EF) was only significative when the AMI was anterior. The incidence of MR was 57.1% when the EF was below 25%. CD had better diagnostic capabilities independently of the site of the AMI, (48% vs 32.1% when the AMI was anterior and 76.1% vs 52.6% when it was inferior).
Thirty healthy individuals with no history of cardiovascular disease were studied to determine the electrocardiographic effects of maximal exercise immediately followed by ingestion of ice water. The ...subjects were subgrouped according to their training into (A) high (N = 5), (B) moderate (N = 14) and (C) low (N = 11) levels. Electrocardiograms (ECGs) were taken at rest and at rest with ingestion of ice water followed by maximal stress tests. Maximal stress tests were repeated followed by ingestion of ice water at the beginning of and at 2, 3, 6 and 9 minutes of recuperation. The stress test combining maximal effort and ice water ingestion was positive in all members of Group A, in 4 from Group B and in 1 from Group C. A stress test associating maximal effort with ice water ingestion is a useful method of detecting subjects susceptible to changes in ECG which appear to be secondary to coronary spasm. It has a low cost it is simple to perform and represents minimal risk.
