[On the possibility of accelerating thrombolytic therapy in the acute phase of myocardial infarction: efficacy of and tolerance to the infusion of 1.5 million units of streptokinase in 30 minutes].

To evaluate efficacy and tolerability of the systemic infusion of 1,500,000 streptokinase units in 30', we treated 26 consecutive patients with acute myocardial infarction within 3 hours of the onset of chest pain. They were 23 men and 3 women, mean age was 59 +/- 8 years. None of them had a history of previous myocardial infarction.

Exercise radionuclide ventriculography after uncomplicated myocardial infarction: what could we gain from the analysis of LVEF throughout the whole test?

To assess the usefulness of a step by step evaluation of exercise left ventricular ejection fraction (LVEF), 219 consecutive patients with recent uncomplicated myocardial infarction and 30 normal subjects underwent a symptom-limited cycloergometer test followed by exercise radionuclide ventriculography (ExRNV). LVEF was monitored throughout the whole test. 49 patients underwent coronary arteriography for clinical reasons.

[Effects of isometric exercise on the right ventricular function and on the pulmonary circulation, in normal subjects (author's transl)].

The pulmonary circulatory response and right ventricular haemodynamics were assessed in normal subjects who sustained hand-grip exercise (HG) at 50% of the maximum voluntary contraction (M.V.C.
