Myocardial infarction subacute

Platelet aggregation appears to be of pivotal importance in several acute or subacute coronary syndromes acute myocardial infarction (MI), unstable angina (UA), postangioplasty ischemia, and poststent-...

There were no differences in the activities of serum transaminases, lactate dehydrogenase, or creatine kinase in patients with myocardial infarction who received an 18-hour infusion of urokinase compared with patients who received glucose alone (38), but subacute alterations of liver function tests have been described with streptokinase and anistreplase (39). Unexplained increases in transaminase activities have been reported in almost 25% of patients treated with streptokinase (40). In view of the greater prominence of liver dysfunction with streptokinase than with alteplase it could be wiser to choose alteplase rather than streptokinase in patients with previous impaired hepatic function (41). 

Figure 2.2 (A) A patient with myocardial infarction of anteroseptal zone in a subacute phase (1) normal recording that displays extension of Q waves up to V6 (qrs). Small changes in the placement of precordial V3-V6 leads have significantly modified the morphology of QRS, now being qR in a lead V6. Therefore, according to the...

Figure 4.66 Above (A) Acute phase of evolving Q-wave myocardial infarction of anteroseptal zone. There is a huge ST-segment elevation, especially in I, VL and from V2 to V5, QRS >0.12 s and morphology of complete RBBB that was not present in previous ECG. (B) Twenty-four hours later RBBB have disappeared and subacute anterior extensive infarction becomes evident. There is ST-segment elevation from V1 to V4. The transient presence of new...
